Dear Shareholders:

The Meeting

You are invited to attend a special meeting (the “Meeting”) of the holders (“Shareholders”) of common shares (“Denison Shares”) of Denison Mines Corp. (“Denison” or the “Corporation”) to be held at the St. Andrew’s Club and Conference Centre, 150 King Street West, Toronto, Ontario on June 25, 2012 at 10:00 a.m. (Toronto time).

Meeting Matters

At the Meeting, pursuant to an interim order of the Ontario Superior Court of Justice (Commercial List) dated May 28, 2012, you will be asked to consider and vote upon a special resolution (the “Arrangement Resolution”) respecting a plan of arrangement (the “Arrangement”) under the Business Corporations Act (Ontario) whereby immediately following the acquisition (the “Purchase and Sale Transaction”) by Energy Fuels Inc. (“Energy Fuels”) of (a) all of the shares of Denison’s subsidiaries holding all of Denison’s mining assets and operations located in the United States of America (the “US Mining Division”) in exchange for payment of Cdn$10.00, and (b) all of the intercompany debt owed by the US Mining Division to Denison (the “Acquired Debt”) in exchange for a promissory note (the “EFI Note”) with a principal amount equal to the aggregate fair market value of 425,441,494 common shares (“EFI Shares”) of Energy Fuels (or approximately 42,544,149 EFI Shares if the EFI Shares are consolidated on a 10-for-1 basis prior to the Arrangement) (collectively, the “EFI Payment Shares”), Denison will complete a reorganization of its capital pursuant to which each issued and outstanding Denison Share will be exchanged for one new common share of Denison (a “New Denison Share”) and an assignment by Denison of a portion of the EFI Note on a pro rata basis. EFI will then repay the EFI Note by issuing the EFI Payment Shares directly to Shareholders in full and final satisfaction of the EFI Note.

The Arrangement and its Effect on Shareholders

If the Arrangement is approved, the US Mining Division and the Acquired Debt will be transferred to Energy Fuels and, pursuant to the reorganization of capital of Denison, Shareholders of record on June 28, 2012 will receive for each Denison Share held one New Denison Share (issued in exchange for the existing Denison Shares) and approximately 1.106 EFI Shares (or approximately 0.1106 of an EFI Share if the EFI Shares are consolidated on a 10-for-1 basis prior to the Arrangement) in repayment of the EFI Note on the effective date of the Arrangement (the “Effective Date”) and the Shareholders will in aggregate own approximately 66.5% of the issued and outstanding EFI Shares. Subject to the approval of the shareholders of Energy Fuels, Energy Fuels expects that it will consolidate the EFI Shares on a 10-for-1 basis subsequent to the Effective Date.

If the requisite Shareholder, regulatory and other approvals are obtained, and if the other conditions to the Arrangement becoming effective are satisfied or waived, it is expected that the Effective Date will be on or about June 29, 2012. As the distribution of the EFI Payment Shares is conditional on the completion of the Purchase and Sale Transaction, the Toronto Stock Exchange (the “TSX”) and the NYSE MKT LLC (the “NYSE MKT”) have approved the use by Denison of Due Bills (as such term is defined in the TSX Company Manual) such that ex-distribution trading of the Denison Shares will commence at the opening of the TSX and the NYSE MKT on the first trading day after the Effective Date, expected to be on or about July 3, 2012 for the TSX and on or about July 2, 2012 for the NYSE MKT. Additional information respecting Due Bills and the trading procedures to be followed are included in the accompanying Information Circular.

- i -

Benefits of the Arrangement

Denison’s Board of Directors (the “Denison Board”) and management believe that proceeding with the proposed Arrangement will provide benefits to Denison and the Shareholders, including, among others, that: the Arrangement will allow Denison to employ more focused operational strategies best suited to growing value in the exploration and development aspects of its business such as its high-profile Wheeler River project in the Athabasca Basin region of northern Saskatchewan and its Mutanga project in Zambia; the Arrangement allows for the continued participation by Shareholders in the US Mining Division’s assets through Energy Fuels; following the completion of the Arrangement, Energy Fuels is expected to emerge as one of the largest solely US pure-play uranium producers and one of the largest holders of US-based uranium; the Arrangement provides for consideration to be received by Shareholders which is, in the opinion of Haywood Securities Inc., fair, from a financial point of view, to Shareholders; the Arrangement preserves the Denison Board’s ability to respond, in accordance with its fiduciary duties, to unsolicited proposals that are more favourable to Shareholders than the Arrangement; is supported by Shareholders holding approximately 10.7% of the outstanding Denison Shares who have entered into support agreements with Energy Fuels pursuant to which they have agreed that they will vote in favour of the Arrangement; the Arrangement permits registered Shareholders who oppose the Arrangement to exercise their dissent rights and receive the fair value of their Denison Shares; and the Arrangement must be approved by 66 ²/3% of the votes cast in person or by proxy at the Meeting and by the Ontario Superior Court of Justice (Commercial List), which will consider the fairness of the Arrangement to the Shareholders.

See “Background to and Reasons for the Arrangement – Reasons for the Arrangement” in the accompanying Information Circular.

Approval of the Arrangement

The Arrangement Resolution must be approved by not less than 66 ²/3% of the votes cast by the Shareholders, either in person or by proxy. The Arrangement is also subject to the approval of the Ontario Superior Court of Justice (Commercial List) and receipt of all necessary regulatory approvals including the approval of the TSX and the NYSE MKT.

Fairness and Recommendation of the Denison Board

The Denison Board has unanimously determined that the Arrangement is fair to Shareholders and is in the best interests of the Corporation, has approved the arrangement agreement between Denison and Energy Fuels dated May 23, 2012 (the “Arrangement Agreement”) and recommends that Shareholders vote in favour of the Arrangement Resolution. The Denison Board came to this determination based on, among other things, the opinion of Haywood Securities Inc. that the consideration to be received by Shareholders pursuant to the Arrangement is fair, from a financial point of view to the Shareholders. See “Fairness Opinion” in the accompanying Information Circular.

Certain Shareholders of the Corporation, and their associates, who own in the aggregate approximately 10.7% of the outstanding Denison Shares, have entered into support agreements pursuant to which they have agreed that they will vote in favour of the Arrangement.

Meeting Matters

Included with this letter are a Notice of Special Meeting and Information Circular. The Information Circular contains a detailed description of the Arrangement, the background to and reasons for the Arrangement and copies of the Plan of Arrangement, the Arrangement Agreement and the Arrangement Resolution. We encourage you to consider carefully all of the information in the Information Circular. If you require assistance, you should consult your financial, legal, tax or other professional advisors.

- ii -

Included with this letter is a form of proxy (“Form of Proxy”) for use by Shareholders. It is important that your Denison Shares be represented at the Meeting. Whether or not you plan to attend the Meeting, you are requested to complete, sign, date and return the enclosed Form of Proxy. To be valid, a Form of Proxy must be signed and deposited with Computershare Investor Services Inc. at 100 University Avenue, 9^th Floor, Toronto, Ontario, M5J 2Y1 (Attention: Proxy Department) not later than 5:00 p.m. (Toronto time) on the date that is two days (excluding Saturdays, Sundays and holidays) prior to the commencement of the Meeting, or any adjournment or postponement thereof. Late proxies may be accepted or rejected by the Chair of the Meeting in his discretion and the Chair is under no obligation to accept or reject any particular late proxy. If you are a registered Shareholder on the Meeting date, voting by proxy will not prevent you from voting in person if you choose to attend the Meeting, but will ensure that your vote will be counted if you are unable to attend. A Shareholder who has given a proxy may revoke it in the manner set out in the Information Circular.

On behalf of the Corporation and the Denison Board, I would like to express our gratitude for the support our Shareholders have demonstrated with respect to our decision to take the proposed Arrangement forward. We look forward to seeing you at the Meeting.

Yours very truly,

DENISON MINES CORP.

SUMMARY OF INFORMATION CIRCULAR

The following is a summary of the contents of this Information Circular and should be read together with the more detailed information and financial data and statements contained elsewhere in this Information Circular. This summary is not intended to be complete and is qualified in its entirety by the more detailed information contained elsewhere in this Information Circular. Shareholders should read the entire Information Circular, including the Appendices. Capitalized terms used in this summary and elsewhere in this Information Circular and not otherwise defined are defined in the Glossary, which follows this summary.

The Arrangement

Denison entered into the Arrangement Agreement with Energy Fuels on May 23, 2012. The Arrangement Agreement provides that Energy Fuels will purchase all of the US Mining Division through the acquisition of the Purchased Shares and the Acquired Debt in consideration for the payment of the Share Consideration and issuance of the EFI Note, which EFI Note will be repaid by the issuance by Energy Fuels of the EFI Payment Shares directly to the Shareholders. Immediately following the completion of the Purchase and Sale Transaction, Denison will complete a reorganization of its capital and will issue to Shareholders one New Denison Share in exchange for each Denison Share held and an assignment by Denison of a portion of the EFI Note on a pro rata basis. EFI will then repay the EFI Note by issuing the EFI Payment Shares directly to Shareholders in full and final satisfaction of the EFI Note. Upon completion of the Arrangement, the US Mining Division will be transferred to Energy Fuels and the holders of record of Denison Shares on the Distribution Record Date will remain Shareholders of Denison and will also become EFI Shareholders on the Effective Date, ultimately receiving for each Denison Share:

(a) following the implementation of the Arrangement, one New Denison Share (issued in exchange for each existing Denison Share held), which will have the same attributes as the existing Denison Shares; and

(b) approximately 1.106 EFI Shares (or approximately 0.1106 of an EFI Post-Consolidation Share if the EFI Share Consolidation is completed prior to the Effective Date).

The foregoing exchange ratios are based upon the assumption that 384,660,915 Denison Shares will be outstanding on the Distribution Record Date. A total of 425,441,494 EFI Shares (42,544,149 EFI Shares if the EFI Share Consolidation is completed prior to the Effective Date) will be issued to Shareholders on a pro rata basis based on an exchange ratio reflecting the actual number of Denison Shares outstanding on the Distribution Record Date.

In the event that the number of outstanding Denison Shares on the Distribution Record Date increases or decreases from the expected number of 384,660,915 Denison Shares, whether as a result of the exercise of stock options of Denison, the exercise of Dissent Rights or otherwise, and in the event that the EFI Share Consolidation is completed, the exchange ratios above and other associated calculations will be adjusted accordingly.

If the requisite Shareholder, regulatory and other approvals are obtained, and if the other conditions to the Arrangement becoming effective are satisfied or waived, it is expected at the Effective Date will be on or about June 29, 2012. As the distribution of the EFI Payment Shares is conditional on the completion of the Purchase and Sale Transaction, the TSX and NYSE MKT have approved the use by Denison of Due Bills such that ex-distribution trading of the Denison Shares will commence at the opening of the TSX and the NYSE MKT on the first trading day after the Effective Date, which is currently anticipated to be on or about July 3, 2012 for the TSX and on or about July 2, 2012 for the NYSE MKT. See “Principal Legal Matters – Due Bills”.

Denison encourages Shareholders to read the full text of the Arrangement Agreement as it is the agreement between Denison and Energy Fuels that governs the Arrangement. See “The Arrangement Agreement”. Similarly, Shareholders are encouraged to read the full text of the Plan of Arrangement as it governs the implementation of the Arrangement. See “The Arrangement – Summary of the Arrangement”. The full text of the Arrangement Agreement and the Plan of Arrangement are attached to this Information Circular as Appendix C and Appendix D, respectively.

- ii -

A copy of the Fairness Opinion is attached as Appendix F to this Information Circular and should be read carefully and in its entirety. See “Fairness Opinion” and Appendix F. The Fairness Opinion was provided solely to the Denison Board in its evaluation of the fairness of the consideration to be received by Shareholders pursuant to the Arrangement and the Fairness Opinion may not be relied upon by any other Person. The Fairness Opinion does not address any other aspect of the Arrangement and does not constitute a recommendation to any Shareholder as to how to vote or act with respect to any matters relating to the Arrangement.

Vote Required to Approve the Arrangement

Subject to any further order of the Court, the Interim Order provides that the Arrangement Resolution must be approved by the affirmative vote thereon at the Meeting by at least 66 ²/3% of the Denison Shares held by Shareholders, present in person or represented by proxy at the Meeting and entitled to vote.

Court Approval

The Arrangement requires the Court’s approval of the Final Order. Prior to the mailing of this Information Circular, Denison obtained the Interim Order authorizing and directing Denison to call, hold and conduct the Meeting and to submit the Arrangement to the Shareholders for approval. A copy of the Interim Order is attached as Appendix B to this Information Circular. Subject to the approval of the Arrangement Resolution by the Shareholders, the hearing in respect of the Final Order is expected to take place at the Ontario Superior Court of Justice (Commercial List) in Toronto, Ontario on June 27, 2012. See “Principal Legal Matters – Court Approval and Completion of the Arrangement” and the Interim Order and Notice of Application for the Final Order at Appendix B.

- vii -

Other Conditions and Approvals

The completion of the Arrangement is also subject to a number of additional conditions and receipt of any required regulatory approvals, in addition to approval of the Shareholders and the Court, which are described in more detail under “The Arrangement Agreement – Conditions of Closing”.

Certain Canadian Federal Income Tax Considerations

There are important tax consequences with respect to the Arrangement. See “Canadian Federal Income Tax Considerations”. On the exchange of Class A Common Shares for New Denison Shares and an interest in the EFI Note pursuant to the Arrangement, a Shareholder resident in Canada will be considered to have received a dividend only to the extent that the interest in the principal amount of the EFI Note that is assigned to such Shareholder exceeds the paid-up capital of the Shareholder’s Class A Common Shares. The Corporation estimates that the principal amount of the EFI Note to be distributed to Shareholders will be less than the paid-up capital of the Class A Common Shares at such time and, as a result, no deemed dividend should arise. Provided the Shareholder has an adjusted cost basis in its Denison Shares of an amount greater than or equal to the value of the EFI Note distributed pursuant to the Arrangement, a Shareholder should not recognize a capital gain on the share exchange under the Arrangement or on the repayment of the EFI Note by the issuance of EFI Payment Shares to the Shareholders.

This Information Circular contains a general summary of the principal Canadian federal income tax considerations relevant to residents and non-residents and which relate to the Arrangement, and the above comments are qualified in their entirety by reference to such summary. See “Certain Canadian Federal Income Tax Considerations”. Shareholders should consult their own tax advisors as to the consequences to them of the Arrangement and the receipt of EFI Shares.

Certain US Federal Income Tax Considerations

Subject to the PFIC rules described under “Certain US Federal Income Tax Considerations”, it is the intent of Denison and Energy Fuels that the exchange of the EFI Note for the Purchased Shares and the Acquired Debt will be treated for US federal income tax purposes as an exchange in which gain or loss is recognized, and the distribution by Denison to its Shareholders of interests in the EFI Note will be treated, with respect to each US Shareholder who is a corporation, as a distribution in an amount equal to the fair market value of the EFI Payment Shares to which such shareholder is entitled pursuant to the Arrangement in payment of such Shareholder’s interest in the EFI Note and taxed as a dividend to the extent of Denison’s current and accumulated earnings and profits (“E&P”), next as a return of capital to the extent of such Shareholder’s tax basis in the Denison Shares, and as a capital gain with respect to any balance in excess of such share of E&P and tax basis. No loss will be recognized if the fair market value of the distribution to any US Shareholder exceeds the sum of such Shareholder’s share of Denison’s E&P and such Shareholder’s basis in the Denison Shares. The holding period with respect to the Class A Common Shares received pursuant to the Arrangement will include the holding period of the Denison Shares. The holding period of the EFI Payment Shares received pursuant to the Arrangement will commence on the date such shares are constructively received pursuant to the Arrangement.

A limited discussion of certain material US federal income tax consequences applicable to US Shareholders resulting from the acquisition, ownership and disposition of the EFI Shares received pursuant to the Arrangement is included under the heading “Certain US Federal Income Tax Considerations” below, and the foregoing is qualified in full by the information in that section. US Shareholders are strongly urged to read that section in its entirety.

This Information Circular contains a general summary of the principal US federal income tax considerations relevant to US Residents and Non-US Residents and which relate to the Arrangement, and the above comments are qualified in their entirety by reference to such summary. See “Certain US Federal Income Tax Considerations”. Shareholders should consult their own tax advisors as to the consequences to them of the Arrangement and the receipt of EFI Shares.

Rights of Dissent

Under the Interim Order, registered holders of Denison Shares on the Record Date have the right to dissent from the Arrangement Resolution upon strict compliance with the Dissent Procedures under Section 185 of the OBCA, the Interim Order and Plan of Arrangement, as described under “Rights of Dissenting Shareholders”. Persons who are beneficial holders of Denison Shares should be aware that only registered holders of Denison Shares are entitled to exercise Dissent Rights. See “Rights of Dissenting Shareholders” and Appendix E to this Information Circular.

Unless waived by Denison, it is a condition to the Arrangement becoming effective that rights of dissent in respect of the Arrangement shall not have been exercised in respect of more than 5% of the Denison Shares.

Procedures for Receipt of EFI Payment Shares

Distribution Record Date

Shareholders of record on the Business Day immediately preceding the Effective Date (the Distribution Record Date), which day is currently expected to be June 28, 2012, will be entitled to receive on the Effective Date, for each Denison Share held, one New Denison Share and approximately 1.106 EFI Shares, or 0.1106 of an EFI Post-Consolidation Share if the EFI Share Consolidation is completed prior to the Arrangement.

Fractional Shares

No certificates representing fractional EFI Shares will be issued upon the repayment of the EFI Note. In the event that the repayment of the EFI Note would otherwise result in the issuance to a Shareholder of a number of EFI Shares which is not a whole number, the EFI Shares to be issued to such Shareholder shall be rounded down to the nearest whole number.

Securities Certificates

Class A Common Share Certificates

Recognizing that the Denison Shares shall be renamed and re-designated as Class A Common Shares and that the Class A Common Shares shall be partially exchanged for New Denison Shares, Denison shall not issue replacement share certificates representing the Class A Common Shares.

New Denison Share Certificates

The Plan of Arrangement provides that from and after the Effective Date, share certificates representing Denison Shares not deemed to have been cancelled pursuant to the exercise of dissent rights shall for all purposes be deemed to be share certificates representing New Denison Shares, and no new share certificates shall be issued with respect to the New Denison Shares issued in connection with the Arrangement. Denison is currently undertaking discussions with CDS and DTC regarding the mechanics for Shareholders to receive their New Denison Shares and their EFI Payment Shares. It is possible that, even though the Plan of Arrangement provides that the certificates representing the Denison Shares will continue to represent the New Denison Shares, Denison may be required to replace the certificates representing the Denison Shares with certificates representing the New Denison Shares, including as a result of CDS and/or DTC requiring a new CUSIP/ISIN number for the New Denison Shares. If Shareholders are required to exchange the existing Denison Share certificates with new certificates for the New Denison Shares, Denison will issue a press release prior to the Effective Date to provide Shareholders with information regarding the procedure that will be implemented to issue new replacement share certificates.

EFI Share Certificates

To facilitate the transfer of the EFI Shares to the Shareholders as of the Distribution Record Date, on or immediately prior to the Effective Time, Energy Fuels will deliver or arrange to be delivered to the Depositary certificates representing the EFI Payment Shares for distribution to Shareholders together with an irrevocable direction to distribute and transfer the EFI Payment Shares to Shareholders in accordance with the Plan of Arrangement. For greater certainty, in the event that the EFI Shares are consolidated on a 10-for-1 basis prior to the completion of the Plan of Arrangement, the EFI Shares will be registered and distributed on a post-consolidation basis only.

- ix -

Risk Factors

There are risks associated with the completion of the Arrangement. Some of these risks include: (a) the Arrangement Agreement may be terminated by Denison or Energy Fuels in certain circumstances, in which case the market price for Denison Shares may be adversely affected; and (b) if Shareholders receive EFI Shares, such receipt will be based on a fixed exchange ratio, the number of EFI Shares to be received by Shareholders will not be adjusted based on fluctuations in the market value of EFI Shares. In addition, Shareholders will become shareholders of EFI as a result of the Arrangement and accordingly will be subject to risks associated with the ownership of EFI Shares. See “Risk Factors” and Appendix G “Information Concerning Energy Fuels – Risk Factors”.

Cautionary Note Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

Information concerning the mineral properties of Denison and Energy Fuels included or incorporated by reference in this Information Circular, including Appendix G “Information Concerning Energy Fuels”, has been prepared in accordance with the requirements of Canadian Securities Laws, which differ in material respects from the requirements of US Securities Laws applicable to US companies subject to the reporting and disclosure requirements of the SEC. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time of the reserve determination, and the SEC does not recognize the reporting of mineral deposits which do not meet the SEC Industry Guide definition of “reserve”. In accordance with NI 43-101, the terms “Mineral Reserve”, “Proven Mineral Reserve”, “Probable Mineral Reserve”, “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” used in this Information Circular or in the documents incorporated by reference in this Information Circular have the meanings ascribed to those terms by the CIM, as the CIM Definition Standards for Mineral Resources and Mineral Reserves adopted by the CIM Council, as amended. While the terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are recognized and required by NI 43-101, the SEC does not recognize them. Shareholders who are US persons are cautioned that, except for that portion of the Mineral Resources classified as Mineral Reserves, Mineral Resources do not have demonstrated economic value. Inferred Mineral Resources have a high degree of uncertainty as to their existence as to whether they can be economically or legally mined. Under Canadian Securities Laws, estimates of Inferred Mineral Resources may not form the basis of an economic analysis. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category.

- 14 -

Therefore, Shareholders are cautioned not to assume that all or any part of an Inferred Mineral Resource exists, that it can be economically or legally mined, or that it will ever be upgraded to a higher category. Likewise, Shareholders are cautioned not to assume that all or any part of Measured Mineral Resource or Indicated Mineral Resources will ever be upgraded to Mineral Reserves.

Section 3(a)(10) of the 1933 Act provides an exemption from the registration requirements of the 1933 Act for offers and sales of securities issued in exchange for one or more outstanding securities where the terms and conditions of the issuance and exchange of such securities have been approved by a court authorized to grant such approval after a hearing upon the fairness of the terms and conditions of the issuance and exchange at which all persons to whom the securities will be issued have the right to appear and receive timely and adequate notice thereof. The Court is authorized to conduct a hearing at which the fairness of the terms and conditions of the Arrangement will be considered. The Court issued the Interim Order on May 28, 2012 and, subject to the requisite approval of the Arrangement Resolution by Shareholders, a hearing on the Arrangement will be held on June 27, 2012 at 10:00 a.m. (Toronto time) at the Ontario Superior Court of Justice (Commercial List), 330 University Avenue, Toronto, Ontario, M5G 1R7, or as soon thereafter as is reasonably practicable. All Shareholders are entitled to appear and be heard at this hearing. The Final Order will constitute the basis for the exemption from the registration requirements of the 1933 Act provided by Section 3(a)(10) thereof with respect to the securities to be issued to and exchanged with the Shareholders pursuant to the Arrangement. Prior to the hearing on the Final Order, the Court will be informed of this effect of the Final Order. See “Principal Legal Matters – Court Approval and Completion of the Arrangement”.

This solicitation of proxies is not subject to the requirements of Section 14(a) of the 1934 Act. Accordingly, the solicitation and transactions contemplated in this Information Circular are made in the United States for securities of a Canadian issuer in accordance with Canadian corporate and securities laws, and this Information Circular has been prepared in accordance with disclosure requirements applicable in Canada. Shareholders in the United States should be aware that such requirements are different from those of the United States applicable to registration statements under the 1933 Act, and proxy statements under the 1934 Act.

The financial statements and other financial information included and incorporated by reference in this Information Circular have been prepared in accordance with Canadian GAAP and IFRS, and are subject to Canadian or Australian, as applicable, accepted auditing standards and auditor independence rules, which differ from United States generally accepted accounting principles and United States auditing and auditor independence standards in certain material respects, and thus may not be comparable to financial statements and financial information of United States companies.

Enforcement by the Shareholders of civil liabilities under the United States federal securities laws may be affected adversely by the fact that Denison and Energy Fuels are organized under the laws of a jurisdiction other than the United States, that certain of their respective officers and directors are residents of countries other than the United States, that certain of the experts named in this Information Circular are residents of countries other than the United States and that certain of the assets of Denison and Energy Fuels and such persons may be located outside the United States. Shareholders may not be able to sue such persons in a non-US court for violations of US Securities Laws. It may be difficult or impossible for Shareholders in the United States to effect service of process within the United States upon the parties to the Arrangement, certain of their respective officers and directors or certain of the experts named herein, or to realize, against them, upon judgments of courts of the United States predicated upon civil liabilities under US Securities Laws. In addition, Shareholders should not assume that the courts of Canada: (a) would enforce judgments of United States courts obtained in actions against such persons predicated upon civil liabilities under US Securities Laws; or (b) would enforce, in original actions, liabilities against such persons predicated upon civil liabilities under US Securities Laws.

The New Denison Shares and the EFI Payment Shares to be issued to and exchanged with the Shareholders pursuant to the Arrangement will be freely transferable under US Securities Laws, except by persons who are “affiliates” of Denison or Energy Fuels, as applicable, after the Effective Date or were affiliates of Denison or Energy Fuels, as applicable, within 90 days prior to the Effective Date. Generally, an “affiliate” of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with the issuer. See “The Arrangement – United States Securities Laws Considerations”.

Shareholders should be aware that the Arrangement and the exchange of their Denison Shares for New Denison Shares, interests in the EFI Note, and EFI Payment Shares may have material tax consequences in the United States, including, without limitation, the possibility that the Arrangement is a taxable transaction, in whole or in part, for United States federal income tax purposes. Certain tax considerations applicable to Shareholders subject to United States federal taxation are discussed under the heading “Certain US Federal Income Tax Considerations”. Shareholders who are resident in, or citizens of, the United States should consult their own tax advisors to determine the particular consequences to them of the Arrangement.

THE NEW DENISON SHARES, INTERESTS IN THE EFI NOTE AND THE EFI PAYMENT SHARES ISSUABLE PURSUANT TO THE ARRANGEMENT HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES REGULATORY AUTHORITY OF ANY STATE OF THE UNITED STATES, NOR HAS THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY SUCH STATE REGULATORY AUTHORITY PASSED ON THE ADEQUACY OR ACCURACY OF THIS INFORMATION CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

Neither the Denison Board nor Denison assumes any responsibility for the accuracy or completeness of such information or for any omission on the part of Energy Fuels to disclose facts or events which may affect the accuracy or completeness of any such information.

No person has been authorized to give any information or to make representations in connection with the Arrangement other than those contained in this Information Circular and, if given or made, any such information or representation should not be considered to have been authorized by Denison or Energy Fuels.

GENERAL PROXY MATTERS

Solicitation of Proxies

This Information Circular is furnished in connection with the solicitation of proxies by management of the Corporation for use at the Meeting, for the purposes set forth in this Information Circular and the accompanying Notice of Meeting. Proxies must be received (either directly or through a Shareholder’s broker or other intermediary) by Computershare Investor Services Inc. at 100 University Avenue, 9^th Floor, Toronto, Ontario, M5J 2Y1 (Attention: Proxy Department) not later than 5:00 p.m. on the date that is two days (excluding Saturdays, Sundays and holidays) prior to the commencement of the Meeting, or any adjournment thereof. Shareholders of record at the close of business on May 25, 2012 (being the Meeting Record Date) will be entitled to vote at the Meeting.

- 16 -

The instrument appointing a proxy must be in writing and be executed by the Shareholder or his or her attorney authorized in writing, or if the Shareholder is a corporation, under its corporate seal or by an officer or attorney thereof duly authorized.

The persons named in the enclosed form of proxy or voting instruction form (each referred to as a “Form of Proxy”) are executive officers of Denison. A Shareholder submitting the proxy has the right to appoint a person (who does not have to be a Shareholder) to represent him or her at the Meeting other than the individuals named in the Form of Proxy. To exercise this right, the Shareholder should insert the name of the desired representative in the blank space provided in the Form of Proxy and strike out the name of the management designee, or submit another appropriate proxy and return it in the enclosed envelope. If a Shareholder plans to attend the Meeting and vote his or her Denison Shares in person, the Shareholder must insert his or her own name in the space provided for on the Form of Proxy to appoint themselves as proxyholder and return it in the enclosed envelope without completing the remainder of the Form of Proxy, as such Shareholder’s votes will be taken at the Meeting.

Notice to Beneficial Holders of Denison Shares

The information set forth in this section is of significant importance to a substantial number of Shareholders who do not hold their Denison Shares in their own name. Shareholders who do not hold their Denison Shares in their own name (referred to in this section as “Beneficial Shareholders”) should note that only proxies deposited by Shareholders whose names appear on the records of the Corporation as the registered holders of Denison Shares can be recognized and acted upon at the Meeting. If Denison Shares are listed in an account statement provided to a Shareholder by a broker, then in almost all cases those Denison Shares will not be registered in such Shareholder’s name on the records of the Corporation. Such Denison Shares will more likely be registered under the name of the Shareholder’s broker or an agent of that broker. In Canada, the vast majority of such Denison Shares are registered under the name of “CDS & Co.” the registration name for CDS, which company acts as a nominee for many Canadian brokerage firms. In the United States, the vast majority of such Denison Shares are registered under the name of “Cede & Co.”, the registration name for DTC, which company acts as a nominee for many US brokers firms. Denison Shares held by brokers or their nominees can only be voted for or against resolutions upon the instructions of the Beneficial Shareholder. Without specific instructions, brokers/nominees are prohibited from voting Denison Shares for their clients. The Corporation does not know for whose benefit the Denison Shares registered in the name of CDS & Co. or Cede & Co. are held.

Applicable regulatory policy requires intermediaries/brokers to seek voting instructions from Beneficial Shareholders in advance of securityholders’ meetings. Every intermediary/broker has its own mailing procedures and provides its own return instructions, which should be carefully followed by Beneficial Shareholders in order to ensure that their Denison Shares are voted at the Meeting. The purpose of a Form of Proxy supplied to a Beneficial Shareholder by its broker is limited to instructing the broker how to vote on behalf of the Beneficial Shareholder. The majority of brokers in Canada and the United States now delegate responsibility for obtaining instructions from clients to Broadridge Investor Communications, Inc. (“Broadridge”). Broadridge typically mails a scannable Voting Instruction Form in lieu of the Instrument of Proxy issued by the Corporation. Beneficial Shareholders are requested to complete and return the Voting Instruction Form to Broadridge by mail or facsimile. Alternatively, Beneficial Shareholders can call a toll-free telephone number or access Broadridge’s dedicated voting website (as noted on the Voting Instruction Form) to deliver their voting instructions and vote the Denison Shares held by them. Broadridge then tabulates the results of all instructions received and provides appropriate instructions respecting the voting of Denison Shares to be represented at the Meeting. A Beneficial Shareholder receiving a Voting Instruction Form cannot use that Voting Instruction Form to vote Denison Shares directly at the Meeting as the Voting Instruction Form must be returned as directed by Broadridge well in advance of the Meeting in order to have the Denison Shares voted. Beneficial Shareholders who receive forms of proxies or voting materials from organizations other than Broadridge should complete and return such forms of proxies or voting materials in accordance with the instructions on such materials in order to properly vote their Denison Shares at the Meeting.

Although a Shareholder may not be recognized directly at the Meeting for the purposes of voting their Denison Shares, a Shareholder may attend at the Meeting as a proxyholder and vote their Denison Shares in that capacity. To do this, a Shareholder must enter their own name in the blank space on the Form of Proxy provided to them and return the document to their broker or other intermediary (or the agent of such broker or other intermediary) in accordance with the instructions provided by such broker, intermediary or agent well in advance of the Meeting.

- 17 -

Revocability of Proxy

A registered Shareholder who has submitted a proxy may revoke it at any time prior to the exercise of that proxy. In addition to revocation in any other manner permitted by law, a proxy may be revoked by (a) instrument in writing executed by the registered Shareholder or his or her attorney authorized in writing or, if the Shareholder is a corporation, under its corporate seal or by an officer or attorney thereof duly authorized, and deposited either at the head office of the Corporation at any time prior to 4:30 p.m. (Toronto time) on the last Business Day before the day of the Meeting, or an adjournment or postponement of the Meeting, or with the Chair of the Meeting on the day of the Meeting, and in either case, the proxy will be considered to be revoked or (b) by transmitting, by telephone or electronic means; a revocation that complies with the timing set out in (a) and that is signed by electronic signature that permits a reliable determination that the document was created or communicated by or on behalf of the Shareholder or the attorney, as the case may be.

Beneficial Shareholders should contact their broker, financial institution or other nominee through which their Denison Shares are held in order to revoke any previous submitted proxy or voting instructions.

Persons Making the Solicitation

This solicitation is made by management of the Corporation. The costs incurred in the preparation and mailing of the Form of Proxy, this Information Circular and the accompanying Notice of Meeting will be borne by the Corporation. In addition to the use of mail, proxies may be solicited by personal interviews, or by other means of communication or by the directors, officers and employees of Denison, who will not be remunerated for such activities.

Exercise of Discretion by Proxy

The Denison Shares represented by proxies in favour of management nominees will be voted in accordance with the instructions of the Shareholder on any ballot that may be called for at the Meeting, and where the Shareholder specifies a choice with respect to any matter to be acted upon, the Denison Shares will be voted in accordance with the specification so made.

In the absence of such specification, such Denison Shares will be voted FOR the matters to be acted upon as set out herein, including the Arrangement Resolution. The persons appointed under the Form of Proxy are conferred with discretionary authority with respect to amendments or variations of those matters specified in the Form of Proxy and Notice of Meeting and with respect to any other matters which may properly be brought before the Meeting. If amendments or variations to matters identified in the Notice of Meeting are properly brought before the Meeting, it is the intention of the persons designated in the enclosed Form of Proxy to vote in accordance with their best judgment on such matter or business. At the time of printing this Information Circular, management of Denison knows of no such amendment, variation, or other matter.

Procedure and Votes Required

The Interim Order provides that each registered Shareholder at the close of business on the Record Date will be entitled to receive notice of and to attend the Meeting.

Pursuant to the Interim Order:

• each Denison Share will entitle a Shareholder to one vote at the Meeting, other than Denison Shares for which Dissent Rights have been exercised;

• the number of votes required to pass the Arrangement Resolution shall be not less than 66 ²/3% of the votes cast by Shareholders voting as a single class, either in person or by proxy, in respect of the Arrangement Resolution at the Meeting; and

• the quorum at the Meeting shall consist of two or more persons either present in person or represented by proxy and representing in the aggregate not less than 10% of the outstanding Denison Shares.

BACKGROUND TO AND REASONS FOR THE ARRANGEMENT

Background to the Arrangement

The Denison Board, with the assistance of Denison’s management, continually reviews options available to Denison to ensure that Shareholders’ value is maximized. As part of this ongoing process, the Denison Board held a strategy session in October, 2011, at which it considered the conditions in the uranium market and options for increasing Shareholder value through restructuring of the Corporation. The Denison Board recognized that the challenging uranium market conditions and disproportionate investor focus on Denison’s US-based production business may have the effect of overshadowing the potential of Denison’s exploration and development business. In light of these factors, the Denison Board determined that management should investigate potential corporate development opportunities with a view to potentially separating Denison’s two distinct business segments, being its mid-sized US production business and its global exploration and development business. The Denison Board considered that the separation of these two units may give investors more choice and unlock value by allowing each business unit to focus on its distinct operations. The Denison Board directed management to identify potential opportunities for further consideration. In late October, 2011, Denison engaged Haywood Securities to provide advice with respect to potential corporate development opportunities, including opportunities relating to the separation of its two business segments.

From late October, 2011, to March, 2012, management of Denison, with the assistance of Haywood Securities, identified a limited number of potential counterparties with respect to a transaction of the kind described above. Denison engaged in informal discussions with a number of these potential parties regarding possible transactions, including transactions relating to the disposition of the US Mining Division. None of the preliminary discussions resulted in any formal negotiations.

One of the parties that had been identified as a potential fit to acquire the US Mining Division was Energy Fuels. On March 6, 2012, Ron Hochstein, President and Chief Executive Officer of Denison, and representatives of Haywood Securities met with Stephen P. Antony, President and Chief Executive Officer of Energy Fuels, and representatives of Dundee Securities Ltd. to discuss potential opportunities with respect to a combination of Energy Fuels and the US Mining Division. At the conclusion of the meeting, Messrs. Hochstein and Antony determined to continue discussions with respect to a potential transaction.

On March 8, 2012, at the regularly scheduled meeting of the Denison Board, management presented to the Denison Board a report prepared by Haywood Securities regarding its assessment of potential corporate development opportunities for Denison relating to the separation of the US Mining Division. Although no formal determination with respect to proceeding with such a transaction was made, the Denison Board indicated its support to management to pursue the potential initiatives that had been identified by management and Haywood Securities, including with respect to a potential transaction with Energy Fuels.

Following the March 8, 2012 meeting, management of Denison conducted further discussions with management of Energy Fuels with respect to a potential transaction. Management of Denison felt at that time that a potential transaction with Energy Fuels may represent the most promising prospect for a transaction of the type being contemplated. Denison and Energy Fuels determined to proceed with further discussions and on March 12, 2012, Denison and Energy Fuels entered into a confidentiality agreement which included customary standstill and non-solicitation clauses. Denison ceased discussions with all other parties with which it had been communicating. Denison commenced preliminary due diligence with respect to Energy Fuels and Energy Fuels began preliminary due diligence with respect to the US Mining Division. On March 15, 2012, Denison engaged Haywood Securities to provide advisory services in connection with the potential sale of the US Mining Division to Energy Fuels. During the second half of March, 2012, Denison and Energy Fuels continued their initial due diligence and began preliminary discussions with respect to potential transaction terms. During this period, Denison consulted its legal and tax advisors with respect to the legal, regulatory and tax issues associated with potential structures which would permit Energy Fuels to acquire the US Mining Division for newly issued shares, and for those shares to be distributed to Shareholders. On March 23, 2012, Denison and Energy Fuels entered into a non-binding letter of intent that set forth a framework for continued discussions and negotiation of a transaction agreement, as well as the parties’ initial mutual understanding of the key terms of a potential transaction. Upon the execution of the letter of intent, Denison and Energy Fuels determined to proceed with discussions on an exclusive basis.

- 19 -

Following the execution of the non-binding letter of intent, each of Denison and Energy Fuels commenced more detailed business due diligence, and directed their respective legal counsel and other advisors to conduct more detailed due diligence on the other party’s business and legal structure. Denison and Energy Fuels also commenced negotiation of a binding agreement setting out the terms of the potential transaction.

On April 2, 2012, Mr. Hochstein met with Mr. Antony, as well as Mark Goodman and Richard Patricio, two of Energy Fuels’ directors, in Toronto to discuss more specific transaction terms and structures. Among the topics discussed at this meeting were the Energy Fuels request that two members of the Denison Board be included on the Energy Fuels Board following closing and integration of the Energy Fuels and the US Mining Division management personnel following completion of the transaction to ensure continuity for the business going forward. Denison also raised the desire to retain two members of the US Mining Division staff for its international projects. The parties also discussed matters related to the transaction structure and the nature and value of the consideration to be exchanged in the transaction. On April 4 and 5, 2012, Mr. Hochstein met with Mr. Antony in Denver, Colorado to discuss the potential transaction in more detail. On April 5, 2012, Denison and Energy Fuels reached a general resolution regarding the value for the US Mining Division and corresponding number of EFI Shares to be issued in the transaction.

On April 9, 2012, the Denison Board met to receive an update with respect to the proposed transaction with Energy Fuels. At that time, the Denison Board received an oral fairness opinion from Haywood Securities with respect to the transaction and discussed the key deal terms that were under discussion. The Denison Board indicated its general support in principle of the transaction as proposed, subject to settlement of the terms of the Letter Agreement in a manner satisfactory to the Denison Board. The Denison Board directed management to continue negotiations with Energy Fuels with respect to the completion of the Letter Agreement. On April 16, 2012, Denison and Energy Fuels settled the final terms of the Letter Agreement. Denison’s Board held a meeting to approve the Letter Agreement. At that meeting Haywood Securities confirmed its oral fairness opinion to the Denison Board. Denison and Energy Fuels executed the Letter Agreement that day and announced the transaction to the public.

Following the execution of the Letter Agreement, Denison’s management began preparations for the Denison meeting and commenced negotiation of the terms of the Arrangement Agreement. Denison and Energy Fuels also completed some final confirmatory due diligence during this period, and Denison’s and Energy Fuels’ tax and legal advisors prepared a further detailed analysis of an appropriate structure to carry out the transaction contemplated by the Letter Agreement. The Letter Agreement provided a deadline to enter into the Arrangement Agreement of May 11, 2012. Discussions with respect to the structure of the Plan of Arrangement, as well as the final terms of the Arrangement Agreement and the Support Agreements, were continuing at May 11, 2012. On May 11, 2012, the parties entered into an amendment to the Letter Agreement which extended the Arrangement Agreement deadline date to May 23, 2012.

Between May 11, 2012 and May 23, 2012, Denison and Energy Fuels continued negotiations on the terms of the Arrangement Agreement including the final structure of the Plan of Arrangement. On May 22, 2012 the Denison Board met to consider the Arrangement Agreement. The Denison Board unanimously approved the terms of the Arrangement Agreement. At this meeting Haywood Securities re-confirmed its oral fairness opinion to the Denison Board. On May 23, 2012, Energy Fuels and Denison agreed on the final terms of the Arrangement Agreement and executed the Arrangement Agreement. The Denison Support Agreements and EFI Support Agreements were concurrently executed and delivered by the applicable directors, officers and shareholders of Denison and Energy Fuels.

Reasons for the Arrangement

In the course of its evaluation of the Arrangement, the Denison Board consulted with senior management, legal counsel and Haywood Securities, conducted due diligence and reviewed publicly available information concerning Energy Fuels, and considered a number of factors including, among others, the following:

(a) Strategic Business Focus. The Arrangement will improve and expand Denison’s ability to focus on and pursue both short and long-term objectives and strategies best suited to a uranium exploration and development company.

(b) Increased Market Clarity. The Arrangement and operational focus resulting from the Arrangement is expected to allow investors and analysts to more accurately compare and evaluate Denison against appropriate peers, benchmarks and performance criteria specific to a mining exploration and development company and that this, in turn, will allow Denison to realize the appropriate valuation for its exploration and development assets which may not have been accorded if all of Denison’s assets continued to be held within the same entity.

- 20 -

(c) Continued Participation by Shareholders in the US Mining Division through Energy Fuels. Under the terms of the Arrangement, Shareholders will receive an aggregate of 425,441,494 EFI Shares on a pro rata basis such that, for each Denison Share held on the Distribution Record Date, a Shareholder will receive approximately 1.106 EFI Shares (or 0.1106 of an EFI Post-Consolidation Share in the event that the EFI Share Consolidation is completed before the Effective Date) and as such will continue to participate in any value increases associated with the development and operation of the US Mining Division.

(d) Fairness Opinion. The Denison Board considered the Fairness Opinion of Haywood Securities to the effect that, as of the date thereof and based upon and subject to the scope of the review, analysis undertaken and various assumptions, limitations and qualifications as set forth in the Fairness Opinion, the consideration to be received by Shareholders pursuant to the Arrangement is fair, from a financial point of view to the Shareholders.

(e) The Terms of the Arrangement Agreement. Under the Arrangement Agreement, the Denison Board remains able to respond, in accordance with its fiduciary duties, to unsolicited proposals that are more favourable than the Arrangement.

(f) Support Agreements. Certain Shareholders holding approximately 10.7% of the outstanding Denison Shares have entered into Support Agreements with Energy Fuels pursuant to which they have agreed that they will vote in favour of the Arrangement.

(g) Dissent Rights. Registered Shareholders who oppose the Arrangement may, upon compliance with certain conditions, exercise their Dissent Rights and receive the fair value of their Denison Shares in accordance with the Plan of Arrangement.

(h) Approval Thresholds. The Denison Board considered the fact that the Arrangement Resolution must be approved by 66 ²/3% of the votes cast in person or by proxy at the Meeting. The Arrangement must also be approved by the Court, which will consider the fairness of the Arrangement to all Shareholders.

In the course of its deliberations, the Denison Board also identified and considered a variety of risks, including:

(a) the consideration received by Denison and ultimately distributed to Shareholders will be in the form of the EFI Note, the principal amount of which is repayable in EFI Shares, the number of EFI Shares to be used to repay the EFI Note is a fixed amount, and the number of EFI Shares to be received by Shareholders pursuant to the Arrangement will not be adjusted based on fluctuations in the market value of EFI Shares; and

(b) the risks to the Corporation if the Arrangement is not completed, including the costs to the Corporation in pursuing the Arrangement and the diversion of management attention away from the conduct of the Corporation’s business.

The foregoing summary of the information and factors considered by the Denison Board is not, and is not intended to be, exhaustive. In view of the variety of factors and the amount of information considered in connection with its evaluation of the Arrangement, the Denison Board did not quantify or otherwise attempt to assign any relative weight to each specific factor considered in reaching its conclusion and recommendation. The Denison Board’s recommendation was made after consideration of all of the above-noted factors and in light of its collective knowledge of the business, financial condition and prospects of the Corporation, and was also based upon the advice of Haywood Securities and legal advisors. In addition, individual members of the Denison Board may have assigned different weights to different factors.

Recommendation of the Denison Board

The Denison Board has unanimously determined that the Arrangement is fair to Shareholders and is in the best interests of Denison, and recommends that Shareholders vote FOR the Arrangement Resolution.

The directors and officers of Denison and their associates beneficially own, directly or indirectly, or exercise control or direction over, an aggregate of approximately 2,819,382 Denison Shares, representing approximately 0.7% of the outstanding Denison Shares. Shareholders, holding an aggregate of 41,019,382 Denison Shares, representing approximately 10.7% of the outstanding Denison Shares, have entered into Denison Support Agreements to vote all of their Denison Shares in favour of the Arrangement Resolution.

- 21 -

FAIRNESS OPINION

On April 9, 2012 and April 16, 2012, prior to Denison executing the Letter Agreement, Haywood Securities delivered an oral fairness opinion to the Denison Board. Haywood Securities confirmed the fairness opinion orally at a meeting held May 22, 2012 prior to Denison executing the Arrangement Agreement. On May 23, 2012, Haywood Securities delivered the Fairness Opinion to the Denison Board. Both the oral fairness opinion and the Fairness Opinion provide that, as of the dates thereof and based upon and subject to the scope of the review, analysis undertaken and various assumptions, limitations and qualifications set forth in the Fairness Opinion, the consideration to be received by the Shareholders pursuant to the Arrangement is fair, from a financial point of view to the Shareholders.

The Fairness Opinion addresses the fairness, from a financial point of view, of the consideration to be received by the Shareholders pursuant to the Arrangement and does not address any other aspect of the Arrangement or any related transaction, including any tax consequences of the Arrangement to Denison or Shareholders. The Fairness Opinion does not address the relative merits of the Arrangement or any related transaction as compared to other business strategies or transactions that might be available to Denison, its associates or affiliates and their respective advisors or otherwise or the underlying business decision of Denison to effect the Arrangement or any related transaction. As set forth in the Fairness Opinion, Haywood Securities has relied upon, and assumed the completeness, accuracy and fair presentation of all financial information, business plans, forecasts, and other information, data, advice, opinions, and representations obtained by Haywood Securities from public sources or provided by or on behalf of Denison. Haywood Securities was not asked to prepare, and has not prepared, a formal valuation or appraisal of Denison or any of its respective assets or securities. The Fairness Opinion does not constitute a recommendation to any Shareholder as to how such Shareholder should vote on the Arrangement Resolution, or how to act with respect to any matters relating to the Arrangement.

Under the terms of the engagement of Haywood Securities, Denison has agreed to pay Haywood Securities a fee for delivery of the Fairness Opinion. In addition, Denison has agreed to reimburse Haywood Securities for its reasonable out-of-pocket expenses, and to indemnify Haywood and related parties against liabilities relating to, or arising out of, its engagement.

The Fairness Opinion, as well as the oral fairness opinion provided by Haywood on April 9, 2012 and April 16, 2012 and confirmed on May 22, 2012, was among the important factors considered by the Denison Board in evaluating the Arrangement and unanimously concluding that the Arrangement is in the best interests of Denison and the Shareholders. See “Background to and Reasons for the Arrangement – Reasons for the Arrangement”.

The full text of the Fairness Opinion including the assumptions made, procedures followed, scope of review, matters considered and limitations on the review undertaken by Haywood is attached at Appendix F to this Information Circular. Shareholders are encouraged to read the Fairness Opinion carefully and in its entirety.

THE ARRANGEMENT

The following is a summary only of the material terms of the Arrangement Agreement and the Plan of Arrangement. Shareholders are urged to read the Arrangement Agreement and the Plan of Arrangement, as attached at Appendix C and Appendix D, respectively.

Summary of the Arrangement

If the issuance of the EFI Payment Shares is approved by the requisite number of EFI Shareholders and the Arrangement is approved by the requisite number of Shareholders and the Court, the following transactions will occur sequentially in the following order, among other things:

(a) Denison and Energy Fuels shall complete the Purchase and Sale Transaction pursuant to which Denison shall sell to Energy Fuels, and Energy Fuels shall purchase from Denison (i) all of the Purchased Shares in consideration and payment of the Share Consideration to Denison and (ii) all of the Acquired Debt in consideration for the issuance of the EFI Note to Denison;

- 22 -

(b) each Denison Share held by a Dissenting Shareholder shall be deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all liens, claims and encumbrances, to Denison and Denison shall thereupon be obliged to pay the amount therefor determined and payable in accordance with Article 4 of the Plan of Arrangement, and the name of such holder shall be removed from the central securities register as a holder of Denison Shares and such Denison Shares so transferred to Denison shall thereupon be cancelled;

(c) in the course of a reorganization of capital:

(i) the authorized share capital of Denison shall be reorganized and altered by:

A. renaming and re-designating all of the issued and unissued Denison Shares as the Class A Common Shares which shares shall have the same rights and restrictions as the Denison Shares except that each Class A Common Share shall be entitled to two votes at any meeting of the Shareholders, and

B. creating an unlimited number of the New Denison Shares without par value, with rights, privileges, restrictions and conditions identical to the Denison Shares;

(ii) Denison’s Articles of Amalgamation (as amended) shall be amended to reflect the alterations in section 3.1(c)(i) of the Plan of Arrangement;

(iii) pursuant to the reorganization, each issued and outstanding Class A Common Share shall be exchanged for one New Denison Share and an assignment by Denison of that portion of the principal amount of the EFI Note determined by dividing the fair market value of the EFI Note by the number of Class A Common Shares outstanding;

(iv) the Class A Common Shares, none of which will be allocated and issued once the steps referred to in section 3.1(c)(iii) of the Plan of Arrangement are completed, shall be cancelled and the authorized capital of Denison shall be changed by deleting the Class A Common Shares as a class of shares of Denison;

(v) the amount added to the stated capital of the New Denison Shares shall be the excess, if any, of (1) paid-up capital (as that term is used for the purposes of the Tax Act) of the Denison Shares (other than the Denison Shares held by the Dissenting Shareholders) immediately prior to the Effective Time, less (2) the principal amount of the EFI Note; and the stated capital of the Class A Common Shares shall, for greater certainty, be nil;

No fractional EFI Shares shall be issued. In the event that the repayment of the EFI Note would otherwise result in the issuance to a Shareholder of a number of EFI Shares which is not a whole number, the number of EFI Shares to be issued to such Shareholder shall be rounded down to the nearest whole number.

On or promptly after the Effective Date, Energy Fuels will deliver or arrange to be delivered to the Depositary certificates representing the EFI Payment Shares to be issued to the Shareholders on the repayment of the EFI Note and in accordance with the provisions of the Arrangement, which certificates shall be held by the Depositary as agent and nominee for such Shareholders for distribution to such Shareholders in accordance with the provisions of the Plan of Arrangement.

Subject to the provisions of Article 5 of the Plan of Arrangement, Shareholders (other than Dissenting Shareholders) shall be entitled to receive delivery of the certificates representing the EFI Shares to which they are entitled pursuant to the Arrangement.

- 23 -

Following the completion of these transactions, the US Mining Division will be owned by Energy Fuels and the Shareholders will in aggregate own approximately 66.5% of the issued and outstanding EFI Shares. See “The Arrangement Agreement” and “Information Concerning Energy Fuels After the Arrangement”.

Interests of Certain Persons or Companies in the Matter to be Acted Upon

To the knowledge of the Denison Board and management and except as otherwise disclosed herein, none of senior management or the directors of Denison, or any associate or affiliate thereof, has a material interest, direct or indirect by way of beneficial ownership of securities or otherwise in the Arrangement.

The officers and directors of Denison and their associates and affiliates beneficially own, directly or indirectly, or exercise control or direction over, in the aggregate, 2,819,382 Denison Shares, representing approximately 0.7% of the Denison Shares outstanding as of the close of business on May 25, 2012. All of the Denison Shares held by the executive officers and directors of Denison will be treated in the same fashion under the Arrangement as Denison Shares held by any other Shareholder.

Vote Required to Approve the Arrangement

Subject to any further order of the Court, the Interim Order provides that the Arrangement Resolution must be approved by the affirmative vote thereon at the Meeting by at least 66 ²/3% of the Denison Shares held by Shareholders, present in person or represented by proxy at the Meeting and entitled to vote.

Denison has been advised that each of the members of the Denison Board and Denison’s senior officers intends to vote the Denison Shares he or she beneficially owns in favour of the Arrangement Resolution.

Denison Support Agreements

Certain Shareholders have entered into Denison Support Agreements pursuant to which each has agreed, subject to the terms thereof, among other things, to vote in favour of the Arrangement Resolution, not to sell or transfer any of their Denison Shares to any person other than Energy Fuels, and not to grant a security interest over such Shareholder’s Denison Shares.

Shareholders holding 41,019,382 Denison Shares (approximately 10.7% of the outstanding Denison Shares), have entered into Denison Support Agreements. The Denison Support Agreements can only be terminated: (a) by mutual consent of Energy Fuels and the Shareholder; (b) if the Arrangement Agreement is terminated in accordance with its terms; (c) by the Shareholder if Energy Fuels has not complied in any material respect with its covenants contained in the Denison Support Agreement or if any representation or warranty of Energy Fuels in the Denison Support Agreement is untrue or incorrect in any material respect and, in each case, such non-compliance or inaccuracy is reasonably likely to prevent consummation of the Arrangement and is not curable or, if curable, is not cured by the earlier of: (i) the date that is five days from the date of written notice of such breach; and (ii) the Business Day prior to the Effective Time; provided that at the time of such termination pursuant to the provisions of the Denison Support Agreement by the Shareholder, the Shareholder is not in default in any material respect in the performance of its obligations under the Denison Support Agreement; and (d) by Energy Fuels if the Arrangement Resolution is not approved by the requisite majority of Shareholders.

Canadian Securities Laws Considerations

The EFI Shares distributed to Shareholders under the Arrangement will be issued in reliance on exemptions from the prospectus requirement of applicable Canadian Securities Laws and will generally not be subject to any resale restrictions under applicable Canadian Securities Laws (provided the conditions set out in Subsection 2.6(3) of National Instrument – Resale of Securities, are satisfied). Shareholders should consult with their own financial and legal advisors with respect to the tradability of the EFI Shares received on completion of the Arrangement.

Multilateral Instrument 61-101 Considerations

The Ontario and Québec securities commissions have adopted Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”), which governs transactions that raise the potential for conflicts of interest, including issuer bids, insider bids, related party transactions and business combinations.

- 24 -

The Arrangement does not constitute an issuer bid, an insider bid or a related party transaction for the purposes of MI 61-101. In assessing whether the Arrangement could be considered a “business combination” for the purposes of MI 61-101, Denison reviewed benefits and payments that related parties of Denison are entitled to receive, directly or indirectly, as a consequence of the Arrangement to determine whether any constituted a “collateral benefit”. For these purposes, the only related parties of Denison that are entitled to a benefit, directly or indirectly, as a consequence of the Arrangement are certain senior officers and directors of Denison. Pursuant to the terms of the employment agreement entered into between Denison Mines (USA) Corp. and Philip G. Buck and the employment agreement entered into between International Uranium (USA) Corporation (a predecessor to Denison Mines (USA) Corp.) and David C. Frydenlund, the Arrangement will be considered to be a “change of control” of Denison Mines (USA) Corp. and accordingly, upon the Effective Date, each of Messrs. Buck and Frydenlund would be entitled to resign and receive a severance amount as specified in each such individual’s employment agreement. It is a condition to the completion of the Arrangement that the Additional Director Nominees be appointed as directors of Energy Fuels at or prior to the Effective Time. The Additional Director Nominees are currently expected to be Ron Hochstein, the President and Chief Executive Officer and a director of Denison, and Robert Dengler, a director of Denison. Directors of Energy Fuels are entitled to annual retainer payments as well as per-meeting fees, and members serving as the chairpersons of committees of the EFI Board are entitled to additional retainers. Directors of Energy Fuels may also receive grants of stock options under Energy Fuels’ stock option plan from time to time at the discretion of the EFI Board. See the information circular for Energy Fuels dated January 10, 2012 for Energy Fuels’ annual general and special meeting dated February 10, 2012 under the heading “Executive Compensation – Director Compensation”, which is incorporated by reference herein, for details regarding the fees payable to members of the EFI Board.

None of these benefits or payments is a “collateral benefit” for the purposes of MI 61-101 since: (i) the benefit is not conferred for the purpose, in whole or in part, of increasing the value of the consideration paid to the related party for the Denison Shares relinquished under the Arrangement; (ii) the benefit is not conditional on the related party supporting the Arrangement in any manner, (iii) full particulars of the benefit have been discussed in this Information Circular, and (iv) each of the related parties receiving the benefit exercised control or direction over, or beneficially owned, less than 1% of the outstanding Denison Shares at the date on which the proposed Arrangement was agreed to.

United States Securities Laws Considerations

The New Denison Shares, the interests in the EFI Note, and the EFI Payment Shares to be issued to and exchanged with Shareholders pursuant to the Arrangement have not been and will not be registered under the 1933 Act, and such securities will be issued in reliance upon the exemption from the registration requirements of the 1933 Act provided by Section 3(a)(10) thereof. Section 3(a)(10) exempts the offer and sale of securities issued in exchange for one or more outstanding securities from the general requirement of registration where the terms and conditions of the issuance and exchange of such securities have been approved by any court of competent jurisdiction, after a hearing upon the fairness of the terms and conditions of the issuance and exchange at which all persons to whom the securities will be issued have the right to appear and receive timely and adequate notice thereof. The Court is authorized to conduct a hearing at which the fairness of the terms and conditions of the Arrangement will be considered. The Court granted the Interim Order on May 28, 2012 and, subject to the approval of the Arrangement by Shareholders, a hearing on the Arrangement will be held on June 27, 2012 by the Court. The Court must determine, prior to approving the Final Order, that the terms and conditions of the issuance and exchange of the New Denison Shares, the interest in the EFI Note and the EFI Payment Shares for the Denison Shares is fair to the Shareholders. The Court has been informed that the approval of the Final Order, if obtained, will constitute the basis for the exemption under Section 3(a)(10) of the 1933 Act with respect to the securities to be issued to and exchanged with the Shareholders pursuant to the Arrangement. See “Principal Legal Matters – Court Approval and Completion of the Arrangement”.

The New Denison Shares and EFI Payment Shares issuable pursuant to the Arrangement will be freely transferable under US Securities Laws, except by persons who are “affiliates” of Denison or Energy Fuels, as applicable, after the Effective Date or were affiliates of Denison or Energy Fuels, as applicable, within 90 days prior to the Effective Date. Persons who may be deemed to be “affiliates” of an issuer generally include individuals or entities that control, are controlled by, or are under common control with, the issuer, whether through the ownership of voting securities, by contract or otherwise and generally include executive officers and directors of the issuer as well as principal shareholders of the issuer. Any resale of such New Denison Shares and EFI Payment Shares by such an affiliate (or, if applicable, former affiliate) may be subject to the registration requirements of the 1933 Act, absent an exemption therefrom. Subject to certain limitations, such affiliates (and former affiliates) may resell such New Denison Shares and EFI Payment Shares outside the United States without registration under the 1933 Act pursuant to Regulation S under the 1933 Act. If available, such affiliates (and former affiliates) may also resell such New Denison Shares and EFI Payment Shares pursuant to Rule 144 under the 1933 Act.

- 25 -

Subject to certain limitations, at any time that Denison or Energy Fuels, as applicable, is a “foreign private issuer” (as defined in Rule 405 under the 1933 Act), Shareholders who are affiliates of Denison or Energy Fuels, as applicable, after the Effective Date or within 90 days prior to the Effective Date, solely by virtue of their status as an officer or director of Denison or Energy Fuels, as applicable, may immediately resell the New Denison Shares and EFI Payment Shares they receive under the Arrangement outside the United States without registration under the 1933 Act pursuant to Regulation S under the 1933 Act. Generally, such persons may resell such securities in an “offshore transaction” if (i) no offer is made to a person in the United States, (ii) either (A) at the time the buyer’s buy order is originated, the buyer is outside the United States, or the seller and any person acting on its behalf reasonably believes that the buyer is outside the United States, or (B) the transaction is executed in, on or through a “designated offshore securities market” (which would include a sale through the TSX) and neither the seller nor any person acting on its behalf knows that the transaction has been pre-arranged with a buyer in the United States, (iii) neither the seller, nor any affiliate of the seller nor or any person acting on any of their behalf engages in any “directed selling efforts” in the United States, and (iv) no selling concession, fee or other remuneration is paid in connection with the offer and sale other than the usual and customary broker’s commission that would be received by a person executing such transaction as agent. For the purposes of Regulation S under the 1933 Act, “directed selling efforts” means any activity undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States for any of the securities being offered in the resale transaction. Shareholders who are affiliates of Denison or Energy Fuels, as applicable, after the Effective Date or within 90 days prior to the Effective Date, not solely by virtue of their status as an officer or director of Denison or Energy Fuels, as applicable, will be subject to additional requirements in order to effect resales of the New Denison Shares and EFI Payment Shares under Rule 903 of Regulation S under the 1933 Act.

In general, under Rule 144 of the 1933 Act, persons who are affiliates of Denison or Energy Fuels, as applicable, after the Effective Date (or were affiliates of Denison or Energy Fuels, as applicable, within 90 days prior to the Effective Date) will be entitled to sell, during any three-month period, the New Denison Shares and EFI Payment Shares that they receive in connection with the Arrangement, provided that the number of such securities sold does not exceed the greater of one percent of the then outstanding securities of such class or, if such securities are listed on a United States securities exchange (such as the NYSE MKT) and/or reported through the automated quotation system of a US registered securities association, the average weekly trading volume of such securities during the four calendar week period preceding the date of sale, subject to specified restrictions on manner of sale, filing requirements, aggregation rules and the availability of current public information about Denison or Energy Fuels, as applicable. Unless certain conditions are satisfied, Rule 144 is not available for resales of securities of issuers that have ever had (i) no or nominal operations and (ii) no or nominal assets other than cash and cash equivalents. If Energy Fuels were ever to be deemed to have been such an issuer in its past, Rule 144 under the 1933 Act may be unavailable for resales of the EFI Payment Shares unless and until Energy Fuels has satisfied the applicable conditions. In general terms, the satisfaction of such conditions would require Energy Fuels to have been a registrant under the 1934 Act for at least 12 months, to be in compliance with its reporting obligations thereunder, and to have filed certain information with the SEC for at least 12 months prior to the intended resale.

For purposes of this section, “United States” means the United States of America, its territories and possessions, any State of the United States and the District of Columbia.

The foregoing discussion is only a general overview of certain requirements of federal US Securities Laws applicable to the resale of the New Denison Shares and EFI Payment Shares received upon completion of the Arrangement. All holders of such New Denison Shares and EFI Payment Shares are urged to consult with counsel to ensure that the resale of their New Denison Shares and EFI Payment Shares complies with applicable securities legislation. Further information applicable to Shareholders in the United States is disclosed under “Introduction – Information for United States Shareholders”.

Effects of the Arrangement

If the Arrangement is successfully completed, the US Mining Division will be owned by Energy Fuels and the Shareholders in aggregate will own approximately 66.5% of the issued and outstanding EFI Shares, with the remaining approximately 33.5% of the outstanding EFI Shares to continue to be owned by existing EFI Shareholders.

Expenses

The estimated fees, costs and expenses of Denison in connection with the Arrangement contemplated herein including, without limitation, financial advisors’ fees, filing fees, legal and accounting fees and printing and mailing costs, excluding taxes and severance payments, are anticipated to be approximately Cdn$2,300,000.

Effective Date of the Arrangement

The Arrangement will be effective upon the Effective Date, which will be the date of filing of Articles of Arrangement (and such other documents that are required to give effect to the Arrangement) with the Director. Denison expects the Effective Date to be on or about June 29, 2012.

Other Material Facts

Denison is not aware of any material facts concerning the securities of Denison or any other matter not described in this Information Circular that has not been previously disclosed and is known to Denison but which would reasonably be expected to affect the decision of the Shareholders with respect to the matters to be voted upon at the Meeting.

THE ARRANGEMENT AGREEMENT

The following is a summary only of the material terms of the Arrangement Agreement. Shareholders are urged to read the Arrangement Agreement in its entirety. A copy of the Arrangement Agreement is attached to this Information Circular at Appendix C.

In addition, Energy Fuels has covenanted to not, without the prior consent of Denison, directly or indirectly do, agree to do, or permit to occur any of the following: (a) declare, set aside or pay any dividend or other distribution or payment in respect of any shares of Energy Fuels; (b) other than as provided for in the Arrangement Agreement, adopt resolutions or enter into any agreement providing for the amalgamation, merger, consolidation, reorganization, liquidation, dissolution or any other extraordinary transaction in respect of Energy Fuels or adopt any plan of liquidation; (c) issue, or enter into any agreement providing for the issuance of EFI Shares or securities exchangeable for or convertible into EFI Shares; or (d) reduce its stated capital.

- 27 -

Exclusivity Covenant of Denison and Energy Fuels

Each of Denison and Energy Fuels have agreed that during the term of the Arrangement Agreement, neither it, its affiliates nor any of their respective representatives, officers, directors, employees, advisors or agents will, directly or indirectly, make, solicit or initiate enquiries from, or the submission of proposals or offers from, any other Person relating to any Acquisition Proposal or participate in any discussions or negotiations regarding, or furnish to any other Person any further information with respect to, or otherwise co-operate in any way with, or assist or participate in or facilitate, any effort or attempt by any person to do or seek to do any of the foregoing and, to the extent any such discussions or negotiations have occurred with third parties prior to the date of the Arrangement Agreement, they shall be terminated immediately. Notwithstanding, the foregoing, a Party may participate in any such discussion or negotiations in respect of transactions which would not materially impede the ability of such Party to, in the case of Energy Fuels, complete the Arrangement and, in the case of Denison, complete the Arrangement, including without limitation, a sale of any of the assets of Denison not owned by the Denison US Group, an acquisition of any other assets by Denison or a transaction involving an acquisition of Denison or other business combination which occurs following or subject to the completion of the Arrangement.

A Receiving Party shall promptly (and in any event within 24 hours) notify the Notified Party, at first orally and then in writing, of any proposal, inquiry, offer or request received by the Receiving Party or its Representatives: (i) relating to an Acquisition Proposal or potential Acquisition Proposal or inquiry that could reasonably lead or be expected to lead to an Acquisition Proposal; (ii) for discussions or negotiations in respect of an Acquisition Proposal or potential Acquisition Proposal; or (iii) for non-public information relating to the Receiving Party or a Subsidiary of the Receiving Party, access to properties, books and records or a list of the holders of the Receiving Party shares or the shareholders of any Subsidiary of the Receiving Party. Such notice shall include the identity of the person making such proposal, inquiry, offer or request, a description of the terms and conditions thereof and the Receiving Party shall provide a copy of any Acquisition Proposal and all written communications with such person and such details of the proposal, inquiry, offer or request that the Notified Party may reasonably request. The Receiving Party shall keep the Notified Party promptly and fully informed of the status, including any change to the material terms, of such proposal, inquiry, offer or request and shall respond promptly to all inquiries by the Notified Party with respect thereto.

Following the receipt by the Receiving Party of a bona fide written Acquisition Proposal made after the date of the Arrangement Agreement (that was not solicited, assisted, initiated, knowingly encouraged or facilitated after the date of the Arrangement Agreement in contravention of the provisions of the Arrangement Agreement), the Receiving Party and its Representatives may:

(a) contact the person making such Acquisition Proposal and its Representatives solely for the purpose of clarifying the terms and conditions of such Acquisition Proposal and the likelihood of its consummation so as to determine whether such Acquisition Proposal is, or is reasonably likely to lead to, a Superior Proposal; and

(b) if the Receiving Party Board determines, after consultation with its outside legal and financial advisors, that such Acquisition Proposal is, or is reasonably likely to lead to, a Superior Proposal: (i) furnish information with respect to the Receiving Party and its Subsidiaries to the person making such Acquisition Proposal and its Representatives only if such person has entered into a confidentiality agreement that contains provisions that are not less favourable to the Receiving Party than those contained in the Confidentiality Agreement, and which also includes a standstill covenant that prohibits such person, for a period of six months, from acquiring, or offering to acquire, any equity securities of the Receiving Party, provided that the Receiving Party sends a copy of such confidentiality agreement to the Notified Party promptly following its execution and the Notified Party is promptly provided with a list of, and access to (to the extent not previously provided to the Notified Party) the information provided to such person; and (ii) engage in discussions and negotiations with the person making such Acquisition Proposal and its Representatives provided that all such information access and discussions shall cease during the Match Period.

- 28 -

Notwithstanding subsection 6.1(b) of the Arrangement Agreement, the Receiving Party may (i) enter into an agreement (other than a confidentiality agreement contemplated by (b) above) with respect to an Acquisition Proposal that is a Superior Proposal and/or (ii) withdraw, modify or qualify its approval or recommendation of the Arrangement and recommend or approve an Acquisition Proposal that is a Superior Proposal, provided: (A) the Receiving Party shall have complied with its obligations under the applicable provisions of the Arrangement Agreement; (B) the Receiving Party Board has determined, after consultation with its outside legal and financial advisors, that such Acquisition Proposal is a Superior Proposal; (C) the Receiving Party has delivered a Superior Proposal Notice to the Notified Party; (D) the Match Period has elapsed since the date the Superior Proposal Notice was received by the Notified Party and the exclusivity period of such Party set forth in the Arrangement Agreement shall automatically be extended so as to terminate no earlier than the second Business Day after the end of the Match Period; (E) if the Notified Party has offered to amend the terms of the Arrangement and the Arrangement Agreement during the Match Period pursuant to the following paragraph, such Acquisition Proposal continues to be a Superior Proposal compared to the amendment to the terms of the Arrangement and the Arrangement Agreement offered by the Notified Party at the termination of the Match Period; and (F) the Receiving Party terminates the Arrangement Agreement in compliance with the applicable terms of the Arrangement Agreement and the Receiving Party has previously paid or, concurrently with termination, pays in cash the Denison Non-Completion Fee or the EFI Non-Completion Fee, as applicable, to the Notified Party.

During the Match Period, the Notified Party shall have the opportunity, but not the obligation, to offer to amend the terms of the Arrangement and the Arrangement Agreement and the Receiving Party shall cooperate with the Notified Party with respect thereto, including negotiating in good faith with the Notified Party to enable the Notified Party to make such adjustments to the provisions of the Arrangement and the Arrangement Agreement as the Notified Party deems appropriate and as would enable the Notified Party to proceed with the Arrangement on such adjusted provisions. The Receiving Party Board shall review any such offer by the Notified Party to amend the terms of the Arrangement and the Arrangement Agreement in order to determine, in good faith in the exercise of its fiduciary duties, whether the Notified Party’s offer to amend the Arrangement and the Arrangement Agreement, upon its acceptance, would result in the Acquisition Proposal ceasing to be a Superior Proposal compared to the amendment to the terms of the Arrangement and the Arrangement Agreement offered by the Notified Party. If the Receiving Party Board determines that the Acquisition Proposal would cease to be a Superior Proposal, the Receiving Party and the Notified Party shall enter into an amendment to the Arrangement Agreement reflecting the offer by the Notified Party to amend the terms of the Arrangement and the Arrangement Agreement.

Each successive material modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of the applicable provision of the Arrangement Agreement.

Representations and Warranties

Under the Arrangement Agreement, Energy Fuels and Denison have each made certain customary representations and warranties related to, among other things, due organization, good standing, authorization to enter into the Arrangement Agreement, reporting status, consents required as a result of the transactions contemplated by the Arrangement Agreement, foreign private issuer status, non-investment company status and that the execution and delivery of the Arrangement Agreement will not result in any violation or breach of such Party’s organizational documents or the creation or imposition of any encumbrances over the assets of such Party or its Subsidiaries. The representations and warranties are, in some cases, subject to specified exceptions and qualifications. In addition, Denison has represented that, on April 17, 2012, Denison delivered the requisite notice to KEPCO as required pursuant to the KEPCO SRA and on May 15, 2012 KEPCO provided Denison with notice that it has determined not to exercise its right of first opportunity provided for in the KEPCO SRA.

(b) The representations and warranties made by Denison in the Arrangement Agreement shall be true and correct as of the Effective Date with the same effect as if made on and as of such date (except to the extent that such representations and warranties speak as of an earlier date, in which event such representations and warranties shall be true and correct as of such earlier date), and Denison shall have provided to Energy Fuels a certificate of two officers thereof certifying such accuracy on the Effective Date. No representation or warranty made by Denison under the Arrangement Agreement shall be deemed not to be true and correct if the facts or circumstances that make such representation or warranty untrue or incorrect are disclosed or referred to in the Denison Disclosure Memorandum, or provided for or stated to be exceptions under the Arrangement Agreement.

If the Arrangement is completed, the business and operations of, and an investment in, Energy Fuels will be subject to the various risk factors set forth under the heading entitled “Risk Factors” in Appendix G. Shareholders who will become holders of EFI Shares as a result of the Arrangement should consider carefully the information contained herein and in the materials incorporated by reference. Additional risks and uncertainties, including those currently unknown, may also adversely affect the businesses of Denison and Energy Fuels going forward. In particular, the Arrangement is subject to certain risks including the following.

- 42 -

Termination of the Arrangement Agreement

Each of Denison and Energy Fuels has the right to terminate the Arrangement Agreement in certain circumstances. Accordingly, there is no certainty, nor can Denison provide any assurance, that the Arrangement Agreement will not be terminated by either Denison or Energy Fuels before the completion of the Arrangement. In addition, the completion of the Arrangement is subject to a number of conditions, certain of which are outside the control of Denison or Energy Fuels, including Shareholders and EFI Shareholders approving the Arrangement and Court approval being obtained. There is no certainty, nor can Denison provide any assurance, that these conditions will be satisfied. If any of the required regulatory and third-party approvals cannot be obtained on terms satisfactory to the Denison Board or at all, the Plan of Arrangement may have to be amended in order to mitigate against the negative consequence of the failure to obtain any such approval, and accordingly, the benefits available to Shareholders resulting from the Arrangement may be reduced. Alternatively, if the Plan of Arrangement cannot be amended so as to mitigate against the negative consequences of the failure to obtain a required regulatory or third-party approval, the Arrangement may not proceed at all. If for any reason the Arrangement is not completed, the market price of Denison Shares may be adversely affected. Moreover, if the Arrangement Agreement is terminated, there is no assurance that the Denison Board will be able to find a party willing to pay an equivalent or a more attractive price for the US Mining Division than the value to be received by Shareholders pursuant to the terms of the Arrangement. Further, if the Arrangement Agreement is terminated, Denison will still have incurred costs for pursuing the Arrangement, including costs related to the diversion of management’s attention away from the conduct of Denison’s business. As well, if the Arrangement Agreement is terminated, in certain circumstances, Denison may be obligated to pay the Energy Fuels Non-Completion Fee.

Possible Failure to Realize the Anticipated Benefits of the Arrangement and Risks Related to Changes to the Business of Denison and to the Integration of the Business of Energy Fuels

The ability of Energy Fuels and Denison to realize the benefits of the Arrangement including, among other things, those benefits set forth under the heading “Background to and Reasons for the Arrangement – Reasons for the Arrangement”, will depend in part on the ability of Denison, following the Arrangement to realize and capitalize on the strategic opportunities resulting from focusing its operations to its primarily exploration and development assets and on the ability of Energy Fuels, following the Arrangement, to realize and capitalize on the anticipated growth and capital opportunities resulting from integrating the US Mining Division with the business and opportunities of Energy Fuels. A variety of factors, including those risk factors set forth in this Information Circular and the documents incorporated by reference herein, may adversely affect the ability of Denison and Energy Fuels to achieve the anticipated benefits of the Arrangement.

In addition, the ability of Denison and Energy Fuels to realize the benefits of the Arrangement will depend in part on successfully transferring and/or integrating, as applicable, functions and operations, procedures and personnel in a timely and efficient manner, as well as on Denison’s ability to transition to a primarily exploration and development company and on Energy Fuels’ ability to realize the anticipated synergies from integrating the acquired Denison business and operations with those of Energy Fuels following completion of the Arrangement. The transition or integration, as applicable, will require the dedication of substantial management effort, time and resources which may divert management’s focus and resources from other strategic opportunities of Denison or Energy Fuels, as applicable, following the completion of the Arrangement, and from operational matters during this process. The transition or integration process, as applicable, may result in the loss of key employees and the disruption of ongoing business, customer and employee relationships that may adversely affect the ability of Denison and Energy Fuels to achieve the anticipated benefits of the Arrangement.

Market Risk Associated with EFI Shares

Shareholders will receive a fixed number of EFI Shares under the Arrangement, rather than EFI Shares with a fixed market value. Because this exchange ratio will not be adjusted to reflect any change in the market value of the EFI Shares, the market value of EFI Shares received under the Arrangement may vary significantly from the market value at the dates referenced in this Information Circular. For example, during the 12-month period ending on September 30, 2011, the closing price of EFI Shares on the TSX varied from a low of Cdn$0.23 to a high of Cdn$1.58 and ended that period at Cdn$0.25. Variations may occur as a result of changes in, or market perceptions of changes in, the business, operations or prospects of Energy Fuels, market assessments of the likelihood the Arrangement will be consummated, regulatory considerations, general market and economic conditions, commodity price changes and other factors over which Energy Fuels has no control.

Risks Relating to Ownership of EFI Shares

An investment in EFI Shares is subject to certain risks. Shareholders should carefully consider the risks described under the heading “Description of the Business – Risk Factors” in the Energy Fuels’ AIF which is incorporated by reference herein as well as the risk factors set forth in Appendix G hereto and elsewhere in this Information Circular.

PRINCIPAL LEGAL MATTERS

Court Approval and Completion of the Arrangement

An arrangement of a corporation under the OBCA requires Court approval. Prior to the mailing of this Information Circular, Denison obtained the Interim Order authorizing and directing Denison to call, hold and conduct the Meeting in accordance with the Notice of Meeting, the OBCA and the Interim Order and, in connection therewith, to submit the Arrangement to the Meeting and to seek approval of the Arrangement Resolution from the Shareholders in the manner set forth in the Interim Order. A copy of the Interim Order is attached at Appendix B to this Information Circular.

Subject to the requisite approval of the Arrangement Resolution by Shareholders at the Meeting, the hearing in respect of the Final Order is scheduled to take place on June 27, 2012 at 10:00 a.m. (Toronto time) at the Ontario Superior Court of Justice (Commercial List), 330 University Avenue, Toronto, Ontario, M5G 1R7, or as soon thereafter as is reasonably practicable. At the hearing for the Final Order, the Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement either as proposed or as amended in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court deems fit. At the hearing, any Shareholder or other person who wishes to appear, or to be represented, or to present evidence or argument must serve and file a Notice of Appearance in accordance with the Ontario Rules of Civil Procedure, serving such notice upon Denison on or before 4:30 p.m. (Toronto time) on June 20, 2012 (being the date that is five Business Days prior to the hearing date for the Final Order) and satisfying any other requirements as provided in the Interim Order. In the event that the hearing is postponed, adjourned or rescheduled then, subject to further notice of the Court, only those persons having previously served a Notice of Appearance in compliance with the Notice of Application and the Interim Order will be given notice of the postponement, adjournment or rescheduled date. Please see the Interim Order attached to this Information Circular as Appendix B for further details.

The New Denison Shares, the interests in the EFI Note and the EFI Payment Shares to be issued to and exchanged with the Shareholders pursuant to the Arrangement have not been and will not be registered under the 1933 Act, and such securities will be issued in reliance upon the exemption from the registration requirements of the 1933 Act provided by Section 3(a)(10) thereof. The Court must determine, prior to approving the Final Order, that the terms and conditions of the exchange of the Denison Shares for the New Denison Shares, the interests in the EFI Note and the EFI Payment Shares is fair to the Shareholders. The Court has been advised that the Final Order approving the Arrangement will constitute the basis for an exemption from the registration requirements of the 1933 Act provided by Section 3(a)(10) thereof, with respect to issuance of the New Denison Shares, the interests in the EFI Note and the EFI Payment Shares issuable to Shareholders pursuant to the Arrangement.

Assuming that the Final Order is granted, and that the other conditions set forth in the Arrangement Agreement are satisfied or waived by the party or parties for whose benefit they exist, then the Articles of Arrangement will be filed with the Registrar to give effect to the Arrangement and all other arrangements and documents necessary to complete the Arrangement will be delivered as soon as reasonably practicable thereafter. Subject to receipt of the Final Order and the satisfaction of the other conditions to the completion of the Arrangement, the Effective Date of the Arrangement is expected to occur on or about June 29, 2012.

Due Bills

Due Bills are entitlements that can be used to defer the ex-dividend trading of listed securities undergoing certain material corporate events such as stock-splits, spin-offs or distributions representing 25% or more of the value of the listed security. Due Bills attach to trades two trading days prior to the applicable record date and come off the day after the payable date. This allows the security to carry the appropriate market value until the entitlement has been paid.

Historically the general process in the Canadian securities industry has been for the listed securities of an issuer to commence trading on an ex-distribution basis (the date on which purchases of the security will no longer have an attaching right to the distribution) at the opening two trading days prior to the record date (the “ex date”). For example, in the event of a material corporate event, listed securities begin to trade on a post-

- 44 -

event basis at the opening of trading on the ex date. Since regular settlement occurs three trading days after the trade date (T+3), purchases that occur on or after the ex date are settled without the entitlement to the additional securities. Valuation issues may occur because the market price drops on the ex date, but the receipt of the entitlement does not occur until the payment date. Client account positions may therefore not be adjusted until the payment date which can lead to confusion.

Without the use of Due Bills, trading on an ex-distribution basis would commence two trading days prior to the Distribution Record Date, and Shareholders would then be deprived of the value of the EFI Payment Shares between the ex date and the Distribution Payment Date. By deferring the ex date through the use of Due Bills, sellers of the Denison Shares during this period can realize the full value of the Denison Shares they hold by selling the Denison Shares with the Due Bills attached. The use of Due Bills will also avoid confusion regarding the market value of the Denison Shares.

Any Denison Shares traded after the Distribution Record Date will represent New Denison Shares as of the Effective Date and shall not carry any rights to receive EFI Shares. As the distribution by Denison of the EFI Payment Shares is conditional on the completion of the Purchase and Sale Transaction, the TSX and the NYSE MKT have approved the use by Denison of Due Bills such that ex-distribution trading of the Denison Shares will commence at the opening of the TSX and the NYSE MKT on the first trading day for each exchange after the Distribution Payment Date (being the Effective Date of the Arrangement), which is currently expected to be on or about July 3, 2012 for the TSX and on or about July 2, 2012 for the NYSE MKT.

Shareholders holding Denison Shares through brokerage accounts will not be required to take any special action. The entitlement will continue to be received into their brokerage accounts on, or immediately after, the Distribution Payment Date. Any trades that are executed during the Due Bill period will be automatically flagged to ensure purchasers receive the entitlement and sellers do not.

Antitrust and other Governmental Approvals

There are no filings, consents, waiting periods or approvals required to be made with, applicable to, or required to be received from any Governmental Entity in Canada in connection with the Arrangement (including under any antitrust law or under the Investment Canada Act) except for the Court’s approval of the Final Order, which will be sought on or about June 27, 2012 and which is a condition to the completion of the Arrangement.

There are no filings, consents, waiting periods or approvals required to be made with, applicable to, or required to be received from any federal Governmental Entity in the United States in connection with the Arrangement (including under the United States Hart–Scott–Rodino Antitrust Improvements Act of 1976, as amended) except for the following. The Arrangement is subject to review under Section 721 of Title VII of the United States Defense Production Act of 1950, as amended, and the rules and regulations thereunder (the “Exon-Florio Amendment”) by the Committee on Foreign Investment in the United States (“CFIUS”). Under the Exon-Florio Amendment, the President of the United States is authorized to prohibit or suspend acquisitions, mergers or takeovers by foreign persons of persons engaged in interstate commerce in the United States if the President determines, after investigation, that there is credible evidence that such foreign persons in exercising control of such acquired persons might take action that threatens to impair the national security of the United States and that other provisions of existing law do not provide adequate authority to protect national security. Pursuant to the Exon-Florio Amendment, a party or parties to a transaction may provide a voluntary notification to CFIUS, which has been designated by the President to administer the Exon-Florio Amendment, for review of the transaction. Notification is not mandatory, but CFIUS has authority to initiate a review of a transaction in the absence of a voluntary notification, including after the transaction has closed. Once a review has been initiated (whether by notification or CFIUS’s own initiative), CFIUS has 30 calendar days to decide whether to initiate a formal investigation. If CFIUS declines to investigate, the review process is complete. If CFIUS decides to investigate, it has 45 days in which to resolve the matter or prepare a recommendation to the President of the United States, who must then decide within 15 days whether to block the transaction. CFIUS may condition its clearance of a transaction upon commitments to be provided by the acquirer. These timetables may be extended in some circumstances if information is not provided as requested. Regardless of whether or not notification is made, there is no prohibition against the consummation of an acquisition, merger or takeover while a review is pending, but CFIUS retains jurisdiction to review a covered transaction following its consummation (unless a review was completed prior to closing). The parties are in contact with CFIUS. The notice is intended to be filed with CFIUS in late May 2012

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the principal Canadian federal income tax consequences under the Tax Act generally applicable as of the date hereof to a Shareholder who, for the purposes of the Tax Act and at all relevant times, is an individual or a corporation, deals at arm’s length with and is not affiliated with the Corporation or Energy Fuels and holds Denison Shares as capital property. Provided a Shareholder does not use or hold its Denison Shares in the course of carrying on a business of buying or selling securities and did not acquire the Denison Shares in one or more transactions considered to be an adventure or concern in the nature of trade, the Denison Shares will generally be capital property to the Shareholder. A Shareholder who is a resident of Canada for purposes of the Tax Act and might not otherwise be considered to hold its Denison Shares as capital property may, in certain circumstances, be entitled to have them and any other “Canadian security” (as defined in the Tax Act) treated as capital property by making the irrevocable election permitted by subsection 39(4) of the Tax Act.

This summary is not applicable to a Shareholder: (i) that is a “financial institution” or a “specified financial institution”, each as defined in the Tax Act; (ii) an interest in which would be a “tax shelter investment” as defined in the Tax Act; or (iii) that has elected to determine its Canadian tax results in a foreign currency pursuant to the functional currency reporting rules.

This summary is based on the current provisions of the Tax Act, all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) before the date hereof (“Proposed Amendments”) and counsel’s understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”). Except for the Proposed Amendments, this summary does not take into account or anticipate any changes in law, whether by legislative, governmental or judicial action, nor does it take into account other federal or any provincial, territorial or foreign income tax legislation or considerations which may differ significantly from the Canadian federal income tax considerations discussed herein. No assurance can be given that the Proposed Amendments will be enacted in the form publicly announced or at all.

This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations applicable to participation in the Arrangement. The income and other tax consequences of participating in the Arrangement will vary depending on a shareholder’s particular status and circumstances, including the province, territory or country in which the shareholder resides or carries on business. This summary is not intended to be, nor should it be construed to be, legal or tax advice to any particular shareholder. Shareholders should consult their own tax advisors for advice with respect to the income tax consequences to them of the Arrangement.

Shareholders Resident in Canada

The following portion of the summary is generally applicable to a Shareholder who, for the purposes of the Tax Act and at all relevant times, is or is deemed to be a resident of Canada.

Re-designation of Denison Shares into Class A Common Shares

The re-designation of the Denison Shares as Class A Common Shares pursuant to the Arrangement should not cause a Shareholder to recognize a capital gain or capital loss. The adjusted cost base to a Shareholder of the Class A Common Shares will be equal to the adjusted cost base that the Shareholder had in their Denison Shares.

Exchange of Class A Common Shares for New Denison Shares and an Interest in the EFI Note

Deemed Dividend

A Shareholder will, on the exchange of his Class A Common Shares for New Denison Shares and an interest in the principal amount of the EFI Note pursuant to the Arrangement (the “Share Exchange”), be considered to have received a dividend to the extent, if any, that the interest in the principal amount of the EFI Note that is assigned to such Shareholder and the paid-up capital of the New Denison Shares received on the exchange exceeds the paid-up capital of such Shareholder’s Class A Common Shares (see “Taxation of Dividends” below).

- 46 -

Provided that the principal amount of the EFI Note that is assigned to the Shareholders is less than the paid-up capital of the Class A Common Shares, Denison will not be deemed to have paid a dividend to Shareholders under subsection 84(3) of the Tax Act. The Corporation estimates that the principal amount of the EFI Note to be distributed to Shareholders on the Share Exchange will be less than the paid-up capital of the Class A Common Shares at such time and, as a result, no deemed dividend should arise.

Current subsection 84(4.1) of the Tax Act deems an amount paid on a reduction of capital by a public corporation to be a dividend paid to its shareholders, other than in certain circumstances. The Corporation is a public corporation for the purposes of the Tax Act. However, subsection 84(4.1) does not apply where a transaction is effected under section 86 of the Tax Act. The Share Exchange will occur under section 86 of the Tax Act and current subsection 84(4.1) of the Tax Act will not apply to deem the distribution made to such shareholder to be a dividend.

Capital Gain

A Shareholder will only recognize a capital gain on the Share Exchange to the extent that the interest in the principal amount of the EFI Note that is assigned to such Shareholder and the adjusted cost base of the New Denison Shares received on the Share Exchange, less the amount of any dividend deemed to be received (as noted above), exceeds the adjusted cost base of the Shareholder’s Class A Common Shares determined immediately before the Share Exchange.

The adjusted cost base to a Shareholder of the interest in the EFI Note that is assigned to the Shareholder will be equal to the portion of the principal amount assigned to such Shareholder. The adjusted cost base to a Shareholder of the New Denison Shares received on the Share Exchange will be equal to the excess, if any, of such Shareholder’s adjusted cost base of the Class A Common Shares over the interest in the principal amount of the EFI Note that is assigned to the Shareholder.

Repayment of EFI Note

The repayment of the EFI Note, which shall be satisfied by the issuance of the EFI Payment Shares to the Shareholders, should not cause a resident Shareholder to recognize a capital gain or capital loss.

Taxation of Dividends

Any dividends received or deemed to be received by a Shareholder will be included in computing the income of such Shareholder and will be subject to the gross-up and dividend tax credit rules normally applicable to taxable dividends paid by a taxable Canadian corporation. A Shareholder that is a corporation will be required to include dividends in computing its income for tax purposes and generally will be entitled to deduct the amount of such dividends in computing its taxable income.

Certain corporations, including private corporations or subject corporations (as such terms are defined in the Tax Act), may be liable to pay a refundable tax at the rate of 33 ¹/3% of such dividends to the extent that such dividends are deductible in computing taxable income.

Taxation of Capital Gains or Capital Losses

One-half of any capital gain realized by a Shareholder will be included in the Shareholder’s income under the Tax Act as a taxable capital gain. One-half of any capital loss realized on the disposition of a Denison Share may be deducted against any taxable gains realized by the Shareholder in the year of disposition, in the three preceding taxation years or any subsequent taxation year, subject to the detailed rules contained in the Tax Act.

In the case of a Shareholder that is a corporation, the amount of any capital loss resulting from the disposition of Denison Shares may be reduced by the amount of dividends previously received or deemed to have been received to the extent and under the circumstances prescribed in the Tax Act. Similar rules may apply where the corporation is a member of a partnership or a beneficiary of a trust that owns Denison Shares, or where a partnership or trust of which the corporation is a member or beneficiary is a member of a partnership or a beneficiary of a trust that owns Denison Shares.

- 47 -

A Shareholder which is a “Canadian-controlled private corporation” (as defined in the Tax Act) throughout the relevant taxation year will be subject to a refundable tax of 6  ²/3% in respect of its aggregate investment income for the year, which will generally include an amount in respect of net taxable capital gains realized in the year. Capital gains realized by individuals and certain trusts may be subject to alternative minimum tax.

Dissenting Shareholders Resident in Canada

A Dissenting Shareholder will be entitled, if the Arrangement becomes effective, to be paid by Denison the fair market value of the Denison Shares held by such Dissenting Shareholder. A Dissenting Shareholder who receives a cash payment from Denison in respect of the fair market value of the Dissenting Shareholder’s Denison Shares will be deemed to have received a dividend equal to the amount, if any, by which the payment exceeds the paid-up capital (computed for purposes of the Tax Act) of such Denison Shares (see “Canadian Federal Income Tax Considerations – Shareholders Resident in Canada – Taxation of Dividends”).

A Dissenting Shareholder will also realize a capital gain (or a capital loss) to the extent that the amount of the payment received from Denison less the amount of any deemed dividend exceeds (or is exceeded by) the adjusted cost base of such Denison Shares to the Dissenting Shareholder and any reasonable costs of disposition (see “Canadian Federal Income Tax Considerations – Shareholders Resident in Canada – Taxation of Capital Gain or Capital Loss”).

In certain circumstances, dividends deemed to be received by a corporate Dissenting Shareholder may be re-characterized as proceeds of disposition under subsection 55(2) of the Tax Act with the result that the corporate Dissenting Shareholder may realize a capital gain. Corporate Dissenting Shareholders should consult their own tax advisors as to the possible application of subsection 55(2) of the Tax Act to payments received on the exercise of dissent rights.

Shareholders Not Resident in Canada

The following portion of the summary is generally applicable to a Shareholder who, for the purposes of the Tax Act and any applicable income tax treaty or convention and at all relevant times, is not resident or deemed to be resident in Canada, does not use or hold the Denison Shares in carrying on business in Canada and is not an insurer who carries on an insurance business in Canada and elsewhere.

Generally, the tax treatment of a Shareholder who is a non-resident of Canada and who participates in the Arrangement will be the same as that described in more detail under the heading “Canadian Federal Income Tax Considerations – Shareholders Resident in Canada”, subject to the comments in the next paragraph.

A Shareholder who is a non-resident of Canada will not be subject to tax under the Tax Act in respect of any capital gain realized by such Shareholder on the Share Exchange unless that Shareholder’s Class A Common Shares constitute “taxable Canadian property” of the Shareholder for purposes of the Tax Act and the Shareholder is not entitled to relief under an applicable tax treaty. As long as the Class A Common Shares are listed on a prescribed stock exchange (which includes the TSX), such shares generally will not constitute taxable Canadian property of a Shareholder unless, at any time during the 5 year period immediately preceding the disposition, 25% or more of the issued shares of any class of Denison were owned or belonged to such Shareholder, alone or together with persons with whom the Shareholder does not deal at arm’s length.

Dissenting Shareholders Not Resident in Canada

A Dissenting Shareholder who receives a cash payment from Denison in respect of the fair market value of the Dissenting Shareholder’s Denison Shares generally will be deemed to have received a dividend equal to the amount, if any, by which the payment exceeds the paid-up capital (computed for purposes of the Tax Act) of such Denison Shares. Under the Tax Act, dividends paid or deemed to have been paid to a non-resident person are subject to withholding tax at the rate of 25%, but such rate may be reduced under the provisions of an income tax treaty or convention in force between Canada and the country of residence of the Dissenting Shareholder.

A Dissenting Shareholder will also realize a capital gain (or a capital loss) to the extent that the amount of the payment received from Denison less the amount of any deemed dividend exceeds (or is exceeded by) the adjusted cost base of such Denison Shares to the Dissenting Shareholder and any reasonable costs of disposition. A Dissenting Shareholder who is a non-resident of Canada will not be subject to tax under the Tax Act in respect of any capital gain realized by such Dissenting Shareholder on a disposition of its Denison Shares, unless such shares constitute taxable Canadian property of the Dissenting Shareholder for the purposes of the Tax Act (as described in more detail under the heading “Canadian Federal Income Tax Considerations – Shareholders Not Resident in Canada”).

CERTAIN US FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the anticipated material US federal income tax consequences to US Holders (as defined below) arising from and relating to the Arrangement as well as the ownership and disposition of EFI Payment Shares received pursuant to the Arrangement.

This summary addresses only Shareholders that are US Holders who are participants in the Arrangement. This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential US federal income tax consequences that may apply to a US Holder as a result of the Arrangement. In addition, this summary does not take into account the individual facts and circumstances of any particular US Holder that may affect the US federal income tax consequences of the Arrangement to such US Holder. Accordingly, this summary is not intended to be, and should not be construed as, legal or US federal income tax advice with respect to any US Holder.

No legal opinion from US legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the US federal income tax consequences of the Arrangement to US Holders. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the US courts could disagree with one or more of the positions taken in this summary.

NOTICE PURSUANT TO IRS CIRCULAR 230: ANYTHING CONTAINED IN THIS SUMMARY CONCERNING ANY US FEDERAL TAX ISSUE IS NOT INTENDED OR WRITTEN TO BE USED, AND IT CANNOT BE USED BY A US HOLDER, FOR THE PURPOSE OF AVOIDING US FEDERAL TAX PENALTIES UNDER THE CODE. THE DISCUSSION BELOW WAS WRITTEN TO SUPPORT DISCLOSURE AND DISSEMINATION OF THE TRANSACTIONS OR MATTERS ADDRESSED BY THIS DOCUMENT (INCLUDING THE ARRANGEMENT). EACH US HOLDER SHOULD SEEK US FEDERAL TAX ADVICE, BASED ON SUCH US HOLDER’S PARTICULAR CIRCUMSTANCES, FROM AN INDEPENDENT TAX ADVISOR.

Scope of this Disclosure

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, published rulings of the IRS, published administrative positions of the IRS, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-US Tax Convention”) and US court decisions that are applicable and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive basis. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis.

US Holders

For purposes of this summary, a “US Holder” is a Shareholder of the Corporation that, for US federal income tax purposes, is (a) an individual who is a citizen or resident of the US, (b) a corporation, or any other entity classified as a corporation for US federal income tax purposes, that is created or organized in or under the laws of the US, any state in the US, or the District of Columbia, (c) an estate if the income of such estate is subject to US federal income tax regardless of the source of such income, or (d) a trust if (i) such trust has validly elected to be treated as a US person for US federal income tax purposes or (ii) a US court is able to exercise primary supervision over the administration of such trust and one or more US persons have the authority to control all substantial decisions of such trust.

- 49 -

Non-US Holders

A “non-US Holder” is any Shareholder other than a US Holder. This summary does not address the US federal income tax consequences of the Arrangement to non-US Holders. Accordingly, non-US Holders should consult their own tax advisors regarding the US federal income, US state and local, and foreign tax consequences (including the potential application and operation of any income tax treaties) of the Arrangement.

US Holders Subject to Special US Federal Income Tax Rules Not Addressed

This summary does not address the US federal income tax consequences of the Arrangement to US Holders that are subject to special provisions under the Code, including the following US Holders: (a) US Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) US Holders that are financial institutions, insurance companies, real estate investment trusts, or regulated investment companies; (c) US Holders that are dealers in securities or currencies or US Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) US Holders that have a “functional currency” other than the US dollar; (e) US Holders that own Denison Shares (or, after the Arrangement, New Denison Shares and EFI Payment Shares) as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) US Holders that hold Denison Shares (or, after the Arrangement, New Denison Shares and EFI Payment Shares) other than as a capital asset within the meaning of Section 1221 of the Code; and (g) US Holders that own (directly, indirectly, or by attribution) 10% or more of the total combined voting power of all classes of shares of the Corporation (and/or after the Arrangement, Energy Fuels) entitled to vote. This summary also does not address the US federal income tax considerations applicable to US Holders who are (a) US expatriates or former long-term residents of the US; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Tax Act; (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Denison Shares (or after the arrangement, New Denison Shares and EFI Payment Shares) in connection with carrying on a business in Canada; (d) persons whose Denison Shares, New Denison Shares or EFI Payment Shares constitute “taxable Canadian property” under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-US Tax Convention. US Holders that are subject to special provisions under the Code, including US Holders described immediately above, should consult their own tax advisors regarding the US federal alternative minimum, US federal estate and gift, US state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of Denison Shares, New Denison Shares or EFI Payment Shares.

If an entity that is classified as a partnership for US federal income tax purposes holds Denison Shares (or, after the Arrangement, New Denison Shares and EFI Payment Shares), the US federal income tax consequences of the Arrangement and owning and disposing of such shares to such partnership and the partners of such partnership generally will depend on the activities of the partnership and the status of such partners. Partners of entities that are classified as partnerships for US federal income tax purposes should consult their own tax advisors regarding the US federal income tax consequences of the Arrangement and the ownership and disposition of Denison Shares, New Denison Shares and EFI Payment Shares.

Transactions Not Addressed

This summary does not address the US federal income tax consequences to US Holders of transactions entered into prior to, concurrently with, or subsequent to the Arrangement (regardless of whether any such transaction is undertaken in connection with the Arrangement), including, but not limited to, the following transactions (without regard as to whether such transactions are considered part of the Arrangement): (a) any conversion, exchange or adjustment of a Denison Option, or other right to acquire Denison Shares; or (b) any conversion, exchange, or adjustment of any note, debenture, or other debt instrument of the Corporation.

US Federal Income Tax Characterization of the Arrangement

The Arrangement will be effected under applicable provisions of Canadian corporate law, which are technically different from analogous provisions of US corporate law. Therefore, the US federal income tax consequences of certain aspects of the Arrangement are not certain. For purposes of this summary, the “Exchange” means (i) the transfer of the Purchased Shares for the cash payment of Cdn$10.00 and transfer of the Acquired Debt to Energy Fuels for the EFI Note, (ii) the redesignation of the Denison Shares as Class A Common Shares, (iii) the deemed exchange of Class A Common Shares for New Denison Shares and a pro rata amount of principal of the EFI Note, and (iv) the issuance by Energy Fuels of the EFI Payment Shares in repayment of the principal amount of the EFI Note.

This summary assumes that the Exchange will be treated by the IRS, under the step-transaction doctrine or otherwise, as if (i) the Corporation transferred the Purchased Shares to Energy Fuels for cash and Acquired Debt to Energy Fuels in exchange for the EFI Payment Shares and then distributed the EFI Payment Shares to Shareholders and (ii) the intervening steps of the Exchange (including those steps of the Exchange described in the preceding sentence) did not occur. However, because the Exchange will be effected under the applicable provisions of Canadian law that are technically different from analogous provisions of US corporate law, there can be no assurances that the IRS or a US court would not take a contrary view of the Exchange. In particular, it is possible that the IRS could analyze the various steps of the Exchange described above separately and independently, and could determine the US federal income tax consequences of the various steps of the Exchange on such a separate and independent basis. The following also assumes that, in all circumstances, the Exchange will be treated as a taxable transaction and will not be recharacterized for US federal income tax purposes as a tax-deferred exchange by Shareholders of the Denison Shares for EFI Payment Shares under Section 368(a) of the Code or as a tax-deferred exchange by the Corporation of the Purchased Shares for the EFI Payment Shares pursuant to Section 368(a)(1)(B) of the Code.

US Federal Income Tax Rules Applicable to US Holders of the Corporation With Respect to the Arrangement

Tax Consequences of the Arrangement if the Corporation Has Not Been a Passive Foreign Investment Company During the US Holder’s Holding Period

Subject to the Passive Foreign Investment Company (“PFIC”) rules discussed below (see “Certain US Federal Income Tax Considerations – US Federal Income Tax Rules Applicable to US Holders of the Corporation with Respect to the Arrangement – Effect of PFIC Rules with Respect to the Receipt of the EFI Payment Shares Pursuant to the Arrangement”), US Holders should experience the following US federal income tax consequences:

Corporate US Holders

A US Holder classified as a corporation for US federal income tax purposes (“Corporate US Holder”) should be treated as receiving a distribution with respect to the value of the EFI Payment Shares. A Corporate US Holder should be required to include the fair market value of the EFI Payment Shares received as a result of the Exchange in gross income (without reduction for any Canadian tax withheld from such amount) as a dividend to the extent of such holder’s share of the current or accumulated earnings and profits of the Corporation, as determined for US federal income tax purposes. To the extent that the fair market value of the EFI Payment Shares exceeds such Corporate US Holder’s share of the current and accumulated earnings and profits of the Corporation, the distribution of the EFI Payment Shares should be treated (a) first, as a tax-free return of capital to the extent of a US Corporate Holder’s tax basis in the exchanged Denison Shares and, (b) thereafter, as gain from the sale or exchange of such Denison Shares. A Corporate US Holder’s tax basis in the EFI Payment Shares will be the fair market value of such shares on the Effective Date of the Arrangement and such Corporate US Holder’s tax basis in the New Denison Shares will equal such Corporate US Holder’s basis in the Denison Shares immediately prior to the Arrangement reduced by that portion of the distribution treated as a return of capital. A Corporate US Holder’s holding period with respect to the New Denison Shares will include the holding period of the Denison Shares. The holding period of the EFI Payment Shares will commence with the date such shares are constructively received pursuant to the Arrangement. No loss will be recognizable as a result of the Arrangement. There are currently no preferential tax rates for long-term capital gains of a US Holder that is a corporation.

Non-Corporate US Holders

The US federal income tax consequences of the Arrangement with respect to US Holders that are not Corporate US Holders will depend on whether the receipt of an interest in the EFI Note pursuant to the Exchange qualifies as a partial liquidation under Section 302(b)(4) and (e) of the Code. Denison does intend to adopt a plan treating the Exchange transactions as a partial liquidation and does not believe that the Exchange transaction will constitute a qualifying partial liquidation of the Corporation. Accordingly, the US federal income tax treatment of US Holders who are not Corporate US Holders (“Non-Corporate US Holders”) will be the same as the treatment described above for Corporate US Holders. Under certain circumstances, a dividend resulting from the distribution of EFI Payment Shares could potentially qualify for the preferential rates applicable to “qualified foreign corporations”, Preferential tax rates apply to long-term capital gains of a US Holder that is an individual, estate or trust.

- 51 -

The determination of what constitutes a corporate contraction is generally factual in nature, and there is no guaranty that the IRS would agree with the Denison’s characterization of the Exchange transaction. If the Exchange transactions were to constitute a partial liquidation within the meaning of Section 302(b)(4) and (e) of the Code, a Non-Corporate US Holder would receive sale or exchange treatment with respect to the EFI Payment Shares. In such case, a Non-Corporate US Holder will recognize gain or loss computed by comparing the fair market value of the EFI Payment Shares received to the basis allocable to such EFI Payment Shares. Under proposed Treasury Regulations, a Non-Corporate US Holder’s basis in the Denison Shares will be allocated between the EFI Payment Shares and the New Denison Shares on the basis of their relative fair market values at Effective Time of the Arrangement.

Denison anticipates that it will not have accumulated earnings and profits as of the Effective Date of the Arrangement nor will it have current earnings and profits for the taxable year during which the Arrangement will close. The calculation of a corporation’s earnings and profits for U.S. federal income tax purposes is highly complex and is open to differing interpretations. In addition, there is no assurance that Denison will not engage in other transactions during its current taxable year which may generate current earnings and profits not presently anticipated. Following the close of its tax year in which the Arrangement is consummated, Denison will endeavour to provide its U.S. Holders with Denison’s determination of its current and accumulated earnings and profits. There is no assurance that the U.S. Internal Revenue Service will agree with such determination. Each U.S. Holder should consult its own tax advisor concerning the U.S. federal income tax treatment of the distribution of the EFI Note.

Tax Consequences of the Arrangement if the Corporation is or Has Been a PFIC During the US Holder’s Holding Period

Status of the Corporation

Special, generally adverse, US federal income tax consequences apply to US taxpayers who hold interests in a PFIC as defined under Section 1297 of the Code, unless certain elections are available and timely and effectively made.

A foreign corporation generally will be a PFIC under Section 1297 of the Code if, for a taxable year, (a) 75% or more of the gross income of the foreign corporation for such taxable year is passive income (the “income test”) or (b) 50% or more of the value of the Corporation’s assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the “asset test”). “Gross income” generally means all sales revenues less the cost of goods sold, and “passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation’s commodities are (a) stock in trade of such foreign corporation or other property of a kind which would properly be included in inventory of such foreign corporation, or property held by such foreign corporation primarily for sale to customers in the ordinary course of business, (b) property used in the trade or business of such foreign corporation that would be subject to the allowance for depreciation under Section 167 of the Code, or (c) supplies of a type regularly used or consumed by such foreign corporation in the ordinary course of its trade or business.

For purposes of the PFIC income test and asset test described above, if a foreign corporation owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, it will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, “passive income” does not include any interest, dividends, rents, or royalties that are received or accrued by the foreign corporation from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income. In addition, under certain attribution rules, if the Corporation is a PFIC, US Holders will be deemed to own their proportionate share of subsidiaries of the Corporation which are PFICs (such subsidiaries referred to as “Subsidiary PFICs”), and will be subject to US federal income tax on (a) a distribution of the shares of a Subsidiary PFIC and (b) a disposition of shares of a Subsidiary PFIC, both as if the holder directly held the shares of such Subsidiary PFIC.

- 52 -

The Corporation has not prepared detailed calculations to determine its PFIC status; however it believes that it was not a PFIC for the taxable years ended December 31, 2011 and December 31, 2010, and based on current business plans and financial projections, does not expect to be a PFIC for its current taxable year. Energy Fuels believes that it was a PFIC in 2011 but has not made any determination as to whether it will not be a PFIC for its current taxable year or future taxable years. The determination of whether any corporation was, or will be, a PFIC for a taxable year depends, in part, on the application of complex US federal income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any taxable year depends on the assets and income of such corporation over the course of each such taxable year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Corporation (or a Subsidiary PFIC) concerning its PFIC status. Each US Holder should consult its own tax advisor regarding the PFIC status of the Corporation, Energy Fuels and each Subsidiary PFIC.

Effect of PFIC Rules with Respect to the Receipt of the EFI Payment Shares Pursuant to the Arrangement

If the Corporation is or has been a PFIC at any time during the period a US Holder has held Denison Shares during such PFIC status period (the “Denison PFIC Shares”), upon the receipt of EFI Payment Shares pursuant to the Arrangement such US Holder, will be subject to special tax rules on any gain or dividend income they realize with respect to such Denison PFIC Shares. Under these special tax rules, the gain or dividend income, if any, a US Holder realizes pursuant to the Arrangement, will be allocated ratably over such US Holder’s holding period for his or her New Denison Shares (which will include the holding period of the Denison PFIC Shares) as follows:

• the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which the Corporation was a PFIC will be treated as ordinary income; and

• the amount allocated to each other year will be taxed at the highest US federal income tax rate on ordinary income in effect for that taxable year, and the interest charge generally applicable to underpayments of tax for the period beginning on the due date for the return applicable to such taxable year and ending with the due date for the return for the current taxable year in which the gain is recognized will be imposed as an addition to the resulting tax attributable to each such year.

• no loss deduction will be allowed with respect to a loss realized upon the receipt of the Denison PFIC Shares unless a Mark-to-Market Election or QEF Election (described below under the heading “Certain US Federal Income Tax Considerations – PFIC Rules Applicable to the Ownership and Disposition of EFI Payment Shares if Energy Fuels is a PFIC”) had previously been made, and in which case special PFIC loss rules will be applicable.

All of the tax and interest described immediately above would be includable in a US Holder’s US federal income tax liability for the taxable year in which the Arrangement takes place. US Holders’ should speak to their tax advisors concerning the US federal income tax consequences of holding or disposing of their shares at a gain in the event that the Corporation is considered a PFIC.

US Holders Exercising Dissent Rights

A US Holder that exercises dissent rights in the Arrangement and is paid cash in exchange for all of such US Holder’s Denison Shares generally will recognize gain or loss in an amount equal to the difference, if any, between (a) the amount of cash received by such US Holder in exchange for Denison Shares (other than amounts, if any, that are or are deemed to be interest for US federal income tax purposes, which amounts will be taxed as ordinary income) and (b) the tax basis of such US Holder in such Denison Shares surrendered. Subject to the PFIC rules discussed in this summary, such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if such Denison Shares are held for more than one year. Preferential tax rates apply to long-term capital gains of a US Holder that is an individual, estate, or trust. Deductions for capital losses are subject to complex limitations under the Code.

US Federal Income Tax Rules Applicable to the Ownership and Disposition of EFI Payment Shares Received in the Arrangement

Distributions on EFI Payment Shares

Subject to the PFIC rules discussed below, a US Holder that receives a distribution, including a constructive distribution, with respect to an EFI Payment Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of Energy Fuels, as computed for US federal income tax purposes. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of Energy Fuels, such distribution will be treated first as a tax-free return of capital to the extent of a US Holder’s tax basis in the EFI Payment Shares and thereafter as gain from the sale or exchange of such EFI Payment Shares. (See “Certain US Federal Income Tax Considerations – US Federal Income Tax Rules Applicable to the Ownership and Disposition of EFI Payment Shares Received in the Arrangement – Sale or Other Taxable Disposition of EFI Payment Shares” below). However, Energy Fuels may not maintain the calculations of earnings and profits in accordance with US federal income tax principles, and each US Holder should therefore assume that any distribution by EFI with respect to the EFI Payment Shares will constitute ordinary dividend income. Dividends received on the EFI Payment Shares generally will not be eligible for the “dividends received” deduction. Distributions by EFI Shares could potentially qualify for the preferential rates applicable to dividends from “qualified foreign corporations”. The dividend rules are complex, and each US Holder may consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of EFI Payment Shares

Subject to the PFIC rules discussed below, upon the sale or other taxable disposition of EFI Payment Shares, a US Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount of cash plus the fair market value of any property received and such US Holder’s tax basis in the shares sold or otherwise disposed of. Subject to the PFIC rules discussed below, gain or loss recognized on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the shares have been held for more than one year.

Preferential rates apply to long-term capital gains of a US Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a US Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

PFIC Rules Applicable to the Ownership and Disposition of EFI Payment Shares if Energy Fuels is a PFIC

Energy Fuels believes that it has been a PFIC for the taxable year ending December 31, 2011 and for all prior taxable years. No determination has been made as to whether EFI will be a PFIC for its current taxable year or future taxable years. If EFI is a PFIC for its current taxable year or future taxable years, the US federal income tax rules applicable to receipt of dividends on account of shares of a PFIC or to gain or loss recognized on the disposition of such PFIC shares are the same as described the section above under the heading “Certain US Federal Income Tax Considerations – US Federal Tax Rules Applicable to US Holders of the Corporation with Respect to the Arrangement – Effect of PFIC Rules With Respect to the Receipt of the EFI Payment Shares Pursuant to the Arrangement”.

A US Holder of shares in a foreign corporation treated as a PFIC may be able to avoid some or all of the consequences described above by making a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”) or electing to treat such foreign corporation as a “qualified electing fund” or “QEF” under Section 1295 of the Code (a “QEF Election”). In the past Energy Fuels has provided to its US Holders who may wish to make QEF Elections the annual information statements needed to make such election. A description of these elections (and other elections that may potentially be made by a US Holder) is beyond the scope of this discussion. The PFIC rules, including the rules governing any elections that may potentially be made by a US Holder, are extremely complex. Each US Holder is urged to consult its own tax advisor regarding the PFIC rules and how the PFIC rules could affect such US Holder.

- 54 -

Foreign Tax Credit

Subject to the PFIC rules discussed above, a US Holder who pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on EFI Shares generally will be entitled, at the election of such US Holder, to receive either a deduction or a credit for such Canadian income tax paid. There are significant and complex limitations that apply to the foreign tax credit, among which is the general limitation that the credit cannot exceed the proportionate share of the US Holder’s US income tax liability that the US Holder’s “foreign source” income bears such US Holder’s worldwide taxable income. In applying this limitation, the various items of income and deduction must be classified as either “foreign source” or “US source”. Complex rules govern this classification process.

Receipt of Foreign Currency

The amount of any distribution paid to a US Holder in foreign currency, or on the sale, exchange or other taxable disposition of EFI Payment Shares, generally will be equal to the US dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into US dollars at that time). If the foreign currency received is not converted into US dollars on the date of receipt, a US Holder will have a basis in the foreign currency equal to its US dollar value on the date of receipt. Any US Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be US source income or loss for foreign tax credit purposes. Each US Holder should consult its own US tax advisor regarding the US federal income tax consequences of receiving, owning, and disposing of foreign currency.

Information Reporting; Backup Withholding Tax

Under US federal income tax law and Treasury regulations, certain categories of US Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, recently enacted legislation generally imposes new US return disclosure obligations (and related penalties) on US Holders that hold certain specified foreign financial assets in excess of US$50,000. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-US person, any financial instrument or contract held for investment that has an issuer or counterparty other than a US person and any interest in a foreign entity. US Holders may be subject to these reporting requirements unless their New Denison Shares or EFI Payment Shares are held in an account at a domestic financial institution. Penalties for failure to file certain of these information returns are substantial. US Holders should consult with their own tax advisors regarding the requirements of filing information returns.

The exchange within the US or by a US payor or US middleman, of the EFI Payment Shares pursuant to the Arrangement as well as payments made within the US, or by a US payor or US middleman, of dividends on, or proceeds arising from the sale or other taxable disposition of New Denison Shares or EFI Payment Shares, generally will be subject to information reporting and backup withholding tax, at the rate of 28% (and increasing to 31% for payments made after December 31, 2012), if a US Holder (a) fails to furnish such US Holder’s correct US taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect US taxpayer identification number, (c) is notified by the IRS that such US Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such US Holder has furnished its correct US taxpayer identification number and that the IRS has not notified such US Holder that it is subject to backup withholding tax. However, US Holders that are corporations generally are excluded from these information reporting and backup withholding tax rules. Any amounts withheld under the US backup withholding tax rules will be allowed as a credit against a US Holder’s US federal income tax liability, if any, or will be refunded, if such US Holder furnishes required information to the IRS. Each US Holder should consult its own tax advisor regarding the information reporting and backup withholding tax rules.

Additional Tax on Passive Income

For tax years beginning after December 31, 2012, certain US Holders who are individuals, estates and trusts and whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on “net investment income” including, among other things, dividends and net gain from disposition of property (other than property held in a trade or business). US Holders should consult with their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of New Denison Shares and EFI Payment Shares.

- 55 -

RIGHTS OF DISSENTING SHAREHOLDERS

In addition to any other right that a Dissenting Shareholder may have, a Dissenting Shareholder who complies with the Dissent Procedures described below is entitled, when the Arrangement becomes effective, to require Denison to pay such holder the fair value of his or her Denison Shares determined as of the close of business on the last Business Day before the day on which the Arrangement Resolution was adopted. The following summary is not a comprehensive statement of the procedures to be followed by a Dissenting Shareholder and is qualified in its entirety by reference to Section 185 of the OBCA, the full text of the Interim Order and the Plan of Arrangement. The full text of Section 185 of the OBCA is set forth as Appendix E to this Information Circular, the Interim Order is set forth at Appendix B to this Information Circular and the Plan of Arrangement is set forth at Appendix D to this Information Circular.

A Court hearing the application for the Final Order has the discretion to alter the Dissent Rights based on the evidence presented at such hearing.

A registered Shareholder is entitled, in addition to any other right such holder may have, to dissent and to be paid by Denison the fair value of the Denison Shares held by such holder, determined as of the close of business on the last Business Day before the day on which the Arrangement Resolution is adopted. Persons who are beneficial Shareholders who wish to dissent with respect to their Denison Shares should be aware that only the registered Shareholders of such Denison Shares are entitled to dissent with respect to them. A non-registered Shareholder who wishes to exercise Dissent Rights should immediately contact the intermediary who deals with his or her Denison Shares and either: (i) instruct the intermediary to exercise the Dissent Rights on the non-registered holder’s behalf (which, if the securities are registered in the name of CDS or DTC or other clearing agency, would require that the securities first be re-registered in the name of the intermediary); or (ii) instruct the intermediary to re-register the securities in the name of the non-registered holder, in which case the non-registered holder would have to exercise the Dissent Rights directly.

A registered Shareholder desiring to exercise Dissent Rights must send to Denison Mines Corp. at Atrium on Bay, Suite 402, 595 Bay Street, Toronto, Ontario, M5G 2C2, Attention: Corporate Secretary on or before 4:30 p.m. (Toronto time) on the Business Day preceding the Meeting, a written Notice of Dissent objecting to the Arrangement Resolution with respect to all the Denison Shares held by such holder. It is important that Dissenting Shareholders strictly comply with this requirement, which is different from the statutory dissent provisions of the OBCA.

The sending of a Notice of Dissent does not deprive such Dissenting Shareholder of its right to vote at the Denison Meeting. A vote against the Arrangement Resolution or the execution of a proxy which is so voted does not itself constitute a Notice of Dissent. Similarly, the revocation of a proxy conferring authority on the proxy holder to vote in favour of the Arrangement Resolution does not constitute a Notice of Dissent in respect of the Arrangement Resolution, but any such proxy granted by a Shareholder who intends to dissent should be validly revoked in order to prevent the proxy holder from voting such Denison Shares in favour of the Arrangement Resolution. A vote in favour of the Arrangement Resolution, whether in person or by proxy, may constitute a waiver of a Shareholder’s right to dissent.

Within ten days after the adoption of the Arrangement Resolution by the Shareholders, Denison is required to notify in writing each Shareholder who has filed a Notice of Dissent and has not voted for the Arrangement Resolution or withdrawn its objection that the Arrangement Resolution has been adopted. A Dissenting Shareholder shall, within 20 days after receiving notice of adoption of the Arrangement Resolution or, if such notice is not received, within 20 days after it learns that the Arrangement Resolution has been adopted, send to Denison a written notice (the “Demand for Payment”) containing such Shareholder’s name and address, the number of Denison Shares in respect of which it dissents and a demand for payment of the fair value of such shares. Within 30 days after sending its Demand for Payment, a Shareholder exercising Dissent Rights shall send the certificates representing the Denison Shares in respect of which it dissents to Denison or its transfer agent. Denison or the transfer agent shall endorse on the share certificates notice that the holder thereof is a Dissenting Shareholder and shall forthwith return the share certificates to the Dissenting Shareholder.

If a Dissenting Shareholder fails to send the Notice of Dissent, the Demand for Payment or his or her share certificates, such Dissenting Shareholder may lose the right to make a dissent claim. After sending a Demand for Payment, a Dissenting Shareholder ceases to have any rights as a holder of Denison Shares in respect of which it has dissented other than the right to be paid the fair value of such shares or options as determined under section 185 of the OBCA, as modified by the Interim Order, unless: (i) the Dissenting Securityholder withdraws its Demand for Payment before Denison makes a written offer to pay for the Dissenting Shareholder’s Denison Shares in an amount considered to be the fair value thereof accompanied by a statement showing how fair value was determined (the “Offer to Pay”); (ii) Denison fails to make a timely Offer to Pay to the Dissenting Shareholder and the Dissenting Shareholder withdraws its Demand for Payment; or (iii) the directors of Denison revoke the Arrangement Resolution, in all of which cases the Dissenting Shareholder’s rights as a Denison Shareholder are reinstated.

- 56 -

Not later than seven days after the later of the date on which the Arrangement Resolution is effective or the day on which Denison receives the Demand for Payment, Denison will send to each Dissenting Shareholder that has sent such notice, an Offer to Pay, or a notification that it is unable lawfully to pay Dissenting Shareholders for their Denison Shares. Every such Offer to Pay for Denison Shares shall be on the same terms. Unless otherwise unable to lawfully pay, Denison shall pay for the Denison Shares of a Dissenting Shareholder within ten days after the Offer to Pay has been accepted, but any offer lapses if not accepted within 30 days. If Denison fails to make such an Offer to Pay, or if a Dissenting Shareholder fails to accept an offer, Denison may within 50 days after the Arrangement is effective, or within such further period as the Court may allow, apply to the Court to fix a fair value for the Denison Shares of such Dissenting Shareholder. If Denison fails to apply to the Court in such manner and within such period, a Dissenting Shareholder may apply to the Court for the same purpose within a further period of 20 days or such further period as the Court may allow. Upon an application to the Court, all Dissenting Shareholders whose Denison Shares have not been purchased by Denison will be joined as parties and be bound by the decision of the Court. Upon any such application to the Court, the Court may determine whether any person is a Dissenting Shareholder who should be joined as a party, and the court will then fix a fair value for the Denison Shares of all Dissenting Shareholders. The Court may, in its discretion allow a reasonable rate of interest on the amount payable to each such Dissenting Shareholder from the date on which the Arrangement is effective until the date of payment. Provided that the Arrangement Resolution becomes effective, a Shareholder that complies with each of the steps required to dissent effectively is entitled to be paid the fair value of the Denison Shares in respect of which such Dissenting Shareholder has dissented.

Notwithstanding Section 185 of the OBCA, Dissenting Shareholders who duly exercise Dissent Rights and who are ultimately entitled to be paid for their Denison Shares will be deemed to have transferred their Denison Shares as of the Effective Time and without any further authorization, act or formality and free and clear of all liens, charges, claims and encumbrances, to Denison at the same time as all other Denison Shares are exchanged for Class A Common Shares and New Denison Share under the Arrangement. In the event that a Dissenting Shareholder fails to perfect or effectively withdraws a claim under Section 185 of the OBCA or forfeits the right to make a claim under that section or his or her rights as a Shareholder are otherwise reinstated, his or her Denison Shares will thereupon be deemed to have been exchanged at the same time as all other Denison Shares are exchanged for Class A Common Shares and New Denison Share under the Arrangement. In no case will such holders be recognized as holders of Denison Shares after the Effective Time.

Unless waived by Denison, it is a condition to the Arrangement becoming effective that rights of dissent in respect of the Arrangement shall not have been exercised in respect of more than 5% of the Denison Shares.

The above is only a summary of the Dissent Rights which are technical and complex. Shareholders desiring to avail themselves of their rights under those provisions should seek their own legal advice, as failure to comply strictly with the provisions of the Interim Order and the OBCA may prejudice their right of dissent.

All Shareholders that are considering exercising Dissent Rights are urged to consult their own tax advisors with respect to the income tax consequences to them of such action.

PROCEDURES FOR RECEIPT OF EFI PAYMENT SHARES

Distribution Record Date

Shareholders of record on the business day immediately preceding the Effective Date (the Distribution Record Date), which day is currently expected to be June 28, 2012, will be entitled to receive on the Effective Date, for each Denison Share held, one New Denison Share and a proportionate share of the 425,441,494 EFI Shares to be distributed by Energy Fuels in repayment of the EFI Note (42,544,149 if the EFI Share Consolidation is completed), representing approximately 1.106 EFI Shares per Denison Share (0.1106 of an EFI Post-Consolidation Share per Denison Share if the EFI Share Consolidation is completed).

- 57 -

Fractional Shares

No certificates representing fractional EFI Shares will be issued upon the repayment of the EFI Note. In the event that the repayment of the EFI Note would otherwise result in the issuance to a Shareholder of a number of EFI Shares which is not a whole number, the EFI Shares to be issued to such Shareholder shall be rounded down to the nearest whole number.

Securities Certificates

Class A Common Share Certificates

Recognizing that the Denison Shares shall be renamed and re-designated as Class A Common Shares and that the Class A Common Shares shall be partially exchanged for New Denison Shares, Denison shall not issue replacement share certificates representing the Class A Common Shares.

New Denison Share Certificates

The Plan of Arrangement provides that, from and after the Effective Date, share certificates representing Denison Shares not deemed to have been cancelled pursuant to the exercise of dissent rights shall for all purposes be deemed to be share certificates representing New Denison Shares, and no new share certificates shall be issued with respect to the New Denison Shares issued in connection with the Arrangement. Denison is currently undertaking discussions with CDS and DTC regarding the mechanics for Shareholders to receive their New Denison Shares and their EFI Payment Shares. It is possible that, even though the Plan of Arrangement provides that the certificates representing the Denison Shares will continue to represent the New Denison Shares, Denison may be required to replace the certificates representing the Denison Shares with certificates representing the New Denison Shares, including as a result of CDS and/or DTC requiring a new CUSIP/ISIN number for the New Denison Shares. If Shareholders are required to exchange the existing Denison Share certificates with new certificates for the New Denison Shares, Denison will issue a press release prior to the Effective Date to provide Shareholders with information regarding the procedure that will be implemented to issue new replacement share certificates.

EFI Share Certificates

To facilitate the transfer of the EFI Shares to the Shareholders as of the Distribution Record Date, on or immediately prior to the Effective Time, Energy Fuels will deliver or arrange to be delivered to the Depositary certificates representing the EFI Payment Shares for distribution to Shareholders together with an irrevocable direction to distribute and transfer the EFI Payment Shares to Shareholders in accordance with the Plan of Arrangement. For greater certainty, in the event that the EFI Shares are consolidated on a 10-for-1 basis prior to completion of the Plan of Arrangement, the EFI Shares will be registered and distributed on a post-consolidation basis only.

INDEBTEDNESS OF DIRECTORS AND EXECUTIVE OFFICERS

No director, executive officer or employee or former director, executive officer or employee of the Corporation or its subsidiaries, nor any proposed nominee for election as a director of Denison, nor any associate of any of the foregoing, is, as at the date hereof, or has been since the beginning of the most recently completed financial year, indebted to the Corporation or any of its subsidiaries or indebted to another entity where the indebtedness is or has been the subject of a guarantee, support agreement, letter of credit or other similar arrangement or understanding provided by the Corporation or any of its subsidiaries.

INTERESTS OF INFORMED PERSONS IN MATERIAL TRANSACTIONS

Except as may otherwise be disclosed herein, no informed person of Denison, nor any director of Denison, or any associate or affiliate of any of the foregoing, has or has had a material interest, direct or indirect, in any transaction since January 1, 2011, or in any proposed transaction that has materially affected or would materially affect the Corporation or any of its subsidiaries.

- 58 -

OTHER MATTERS

As of the date of this Information Circular, the Denison Board and management of Denison know of no amendment, variation or other matter to come before the Meeting other than the matters referred to in the Notice of Meeting. However, if any other matter properly comes before the Meeting, the accompanying proxies will be voted on such matter in accordance with the best judgment of the person or persons voting the proxy.

24. THIS COURT ORDERS that any Denison Shareholder who duly exercises such Dissent Rights set out in paragraph 22 above and who:

(r) Title to Properties and Condition of Assets. The EFI Disclosure Memorandum provides a list of all of the mineral properties that are material to EFI, taken as a whole (the “EFI Material Properties”). Except as disclosed in either the EFI Disclosure Memorandum or the EFI Public Disclosure Documents, applying customary standards in the mining industry, EFI has sufficient title to or valid leasehold interests in the EFI Material Properties to operate such properties in the ordinary course and consistent with past practice, free and clear of any title defect or Encumbrance, except for such defects in title or Encumbrances that, individually or in the aggregate, do not have, and would not reasonably be expected to have, a Material Adverse Effect on EFI. Each lease and agreement granting rights to the EFI Material Properties is in full force and effect and constitutes a legal, valid and binding agreement of EFI or an EFI Material Subsidiary thereof and EFI and/or the EFI Material Subsidiary, as the case may be, is not in violation or breach of or default under any such lease or agreement except such violations, breaches or defaults which, individually, or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on EFI. Furthermore, all real and tangible personal property of EFI and the EFI Material Subsidiaries is in generally good repair and is operational and usable in the manner in which it is currently being utilized, subject to normal wear and tear and technical obsolescence, repair or replacement except for such property where the failure to be in such condition would not reasonably be expected to have a Material Adverse Effect on EFI.

If any of such conditions shall not be complied with or waived by EFI on or before the Effective Time or, if earlier, the date required for the performance thereof, then, subject to Section 5.4 and Section 6.2 and Section 6.3, EFI may terminate this Agreement by written notice to Denison in circumstances where the failure to satisfy any such condition is not the result, directly or indirectly, of a breach of this Agreement by EFI.

No representation or warranty made by EFI hereunder shall be deemed not to be true and correct if the facts or circumstances that make such representation or warranty untrue or incorrect are disclosed or referred to in the EFI Disclosure Memorandum, or provided for or stated to be exceptions under this Agreement.

(c) No Material Adverse Effect. There shall not have been any event or change that has had or would reasonably be expected to have a Material Adverse Effect on EFI.

(g) Necessary Corporate Actions Taken. The board of directors of EFI shall have adopted all necessary resolutions and all other necessary corporate action shall have been taken by EFI to permit the consummation of the Arrangement and the other transaction contemplated hereby, including the appointment of the Additional Director Nominees to the board of directors of EFI effective at the Effective Time.

The foregoing conditions are for the benefit of Denison and may be waived, in whole or in part, by Denison in writing at any time. If any of such conditions shall not be complied with or waived by Denison on or before the Completion Deadline or, if earlier, the date required for the performance thereof, then, subject to Section 5.4 and Section 6.2 and Section 6.3, Denison may terminate this Agreement by written notice to EFI in circumstances where the failure to satisfy any such condition is not the result, directly or indirectly, of a breach of this Agreement by Denison.

5.4 Notice and Cure Provisions

Each Party shall give prompt notice to the other Party of the occurrence, or failure to occur, at any time from the date hereof until the Effective Date, of any event or state of facts which occurrence or failure would, would be likely to or could:

Neither Party may (a) elect not to complete the Arrangement by virtue of the conditions contained in Section 5.1, Section 5.2 and Section 5.3 hereof, as applicable, not being satisfied or waived or (b) exercise any termination right arising therefrom; unless (i) promptly and in any event prior to the Effective Date, the Party intending to rely thereon has delivered a written notice to the other Party specifying in reasonable detail the breaches of covenants or untruthfulness or inaccuracy of representations and warranties or other matters that the Party delivering such notice is asserting as the basis for the exercise of the termination right, as the case may be, and (ii) if any such notice is delivered, and a Party is proceeding diligently, at its own expense, to cure such matter, if such matter is susceptible to being cured, the Party that has delivered such notice may not terminate this Agreement until the earlier of the Completion Deadline and the expiration of a period of 15 days from date of delivery of such notice.

5.5 Merger of Conditions

Upon the issuance of the Final Order and the closing of the Arrangement, the conditions set out in Section 5.1, Section 5.2 and Section 5.3 hereof shall be conclusively deemed to have been satisfied, fulfilled or waived as of the Effective Time.

- 62 -

(b) Superior Proposal. Following the receipt by the Receiving Party of a bona fide written Acquisition Proposal made after the date of this Agreement (that was not solicited, assisted, initiated, knowingly encouraged or facilitated after the date hereof in contravention of Section 4.1(e) or Section 4.2(e), as the case may be), the Receiving Party and its Representatives may:

(i) contact the person making such Acquisition Proposal and its Representatives solely for the purpose of clarifying the terms and conditions of such Acquisition Proposal and the likelihood of its consummation so as to determine whether such Acquisition Proposal is, or is reasonably likely to lead to, a Superior Proposal; and

(ii) if the board of directors of the Receiving Party (the “Receiving Party Board”) determines, after consultation with its outside legal and financial advisors, that such Acquisition Proposal is, or is reasonably likely to lead to, a Superior Proposal:

A. furnish information with respect to the Receiving Party and its Subsidiaries to the person making such Acquisition Proposal and its Representatives only if such person has entered into a confidentiality agreement that contains provisions that are not less favourable to the Receiving Party than those contained in the Confidentiality Agreement, and which also includes a standstill covenant that prohibits such person, for a period of 6 months, from acquiring, or offering to acquire, any equity securities of the Receiving Party, provided that the Receiving Party sends a copy of such confidentiality agreement to the Notified Party promptly following its execution and the Notified Party is promptly provided with a list of, and access to (to the extent not previously provided to the Notified Party) the information provided to such person; and

B. engage in discussions and negotiations with the person making such Acquisition Proposal and its Representatives provided that all such information access and discussions shall cease during the Match Period (as defined below).

(c) Change in Recommendation. Notwithstanding Section 6.1(b), the Receiving Party may (i) enter into an agreement (other than a confidentiality agreement contemplated by subsection 6.1(b)(ii)A hereof) with respect to an Acquisition Proposal that is a Superior Proposal and/or (ii) withdraw, modify or qualify its approval or recommendation of the Arrangement and recommend or approve an Acquisition Proposal that is a Superior Proposal, provided:

(i) the Receiving Party shall have complied with its obligations under Section 4.1(e) or Section 4.2(e), as the case may be, and under this Section 6.1;

(ii) the Receiving Party Board has determined, after consultation with its outside legal and financial advisors, that such Acquisition Proposal is a Superior Proposal;

- 63 -

(iii) the Receiving Party has delivered written notice to the Notified Party of the determination of the Receiving Party Board that the Acquisition Proposal is a Superior Proposal and of the intention of the Receiving Party Board to approve or recommend such Superior Proposal and/or of the Receiving Party to enter into an agreement with respect to such Superior Proposal, together with a copy of such agreement executed by the person making such Superior Proposal that is capable of acceptance by the Receiving Party and a summary of the valuation analysis attributed by the Receiving Party Board in good faith to any non-cash consideration included in such Acquisition Proposal after consultation with its financial advisors (the “Superior Proposal Notice”);

(iv) at least five Business Days have elapsed since the date the Superior Proposal Notice was received by the Notified Party, which five Business Day period is referred to as the “Match Period” and the exclusivity period in Section 4.1(e) or Section 4.2(e), as the case may be, shall automatically be extended so as to terminate no earlier than the second Business Day after the end of the Match Period;

(v) if the Notified Party has offered to amend the terms of the Arrangement and this Agreement during the Match Period pursuant to paragraph (d) below, such Acquisition Proposal continues to be a Superior Proposal compared to the amendment to the terms of the Arrangement and this Agreement offered by the Notified Party at the termination of the Match Period; and

(vi) the Receiving Party terminates this Agreement in compliance with the terms of this Section 6.1 and the Receiving Party has previously paid or, concurrently with termination, pays in cash the termination payment referred to in Section 6.3 to the Notified Party.

(d) Amendments. During the Match Period, the Notified Party shall have the opportunity, but not the obligation, to offer to amend the terms of the Arrangement and this Agreement and the Receiving Party shall cooperate with the Notified Party with respect thereto, including negotiating in good faith with the Notified Party to enable the Notified Party to make such adjustments to the provisions of the Arrangement and this Agreement as the Notified Party deems appropriate and as would enable the Notified Party to proceed with the Arrangement on such adjusted provisions. The Receiving Party Board shall review any such offer by the Notified Party to amend the terms of the Arrangement and this Agreement in order to determine, in good faith in the exercise of its fiduciary duties, whether the Notified Party’s offer to amend the Arrangement and this Agreement, upon its acceptance, would result in the Acquisition Proposal ceasing to be a Superior Proposal compared to the amendment to the terms of the Arrangement and this Agreement offered by the Notified Party. If the Receiving Party Board determines that the Acquisition Proposal would cease to be a Superior Proposal, the Receiving Party and the Notified Party shall enter into an amendment to this Agreement reflecting the offer by the Notified Party to amend the terms of the Arrangement and this Agreement.

(e) Successive Modifications. Each successive material modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of this Section 6.1.

- 64 -

6.2 Termination

This Agreement may be terminated:

(a) by either party if the conditions precedent to completion of the Arrangement set out in Section 5.1, Section 5.2 and Section 5.3, are not satisfied and are not reasonably capable of being satisfied on or prior to the Completion Deadline;

(b) by either party if such party determines, acting reasonably, that it or the other party will not be able to obtain the consents and approvals referred to in Sections 5.1(b), 5.1(c) and 5.1(d) in form satisfactory to either party, acting reasonably;

(c) by either party in accordance with Section 6.1 if such party receives a Superior Proposal;

(d) by either party if such party determines that the representations and warranties of the other party set out in this Agreement are materially incorrect, and are not capable of being corrected or remedied within a reasonable time period; or

(e) by either party if such party determines that the other party has not complied with its material obligations under this Agreement within the time period provided for herein or therein.

6.3 Termination Payment

(a) In the event that this agreement is terminated:

(i) as a consequence of the failure to obtain the approval of Denison shareholders as contemplated by Section 5.1(c) if a third party has announced prior to the time of the Denison Meeting an Acquisition Proposal relating to Denison or an intention to make an Acquisition Proposal relating to Denison, in either case which represents a Superior Proposal, and such proposal or intention is still in effect at the time of the Denison Meeting;

(ii) by Denison pursuant to Section 6.2(c);

(iii) by EFI pursuant to Section 6.2(d) or Section 6.2(e),

then Denison shall pay a termination payment in the amount of Cdn$3,000,000 as liquidated damages for the loss of Denison’s rights under this Agreement to EFI at the time of such termination in immediately available funds. Denison shall not be obligated to make more than one payment pursuant to this Section 6.3(a). Denison hereby acknowledges that the payment amount set out in this section is a payment of liquidated damages which are a genuine pre-estimate of the damages which EFI will suffer or incur as a result of the event giving rise to such damages and the resultant non-completion of the Arrangement and are not penalties. Denison hereby irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. Upon receipt of payment of the amount set out in this subsection by EFI, EFI shall have no further claim against Denison in respect of the failure to complete the Arrangement, provided that nothing herein shall preclude EFI from seeking injunctive relief to restrain any breach or threatened breach by Denison of any of its obligations hereunder or otherwise to obtain specific performance without the necessity of posting a bond or security in connection therewith as described in Section 8.4.

- 65 -

(b) In the event that this Agreement is terminated:

(i) as a consequence of the failure to obtain the approval of EFI Shareholders as contemplated by Section 5.1(d) if a third party has announced prior to the time of the EFI Meeting an Acquisition Proposal relating to EFI or an intention to make an Acquisition Proposal relating to EFI, in either case which represents a Superior Proposal, and such proposal or intention is still in effect at the time of the Denison Meeting;

(ii) by EFI pursuant to Section 6.2(c); or

(iii) by Denison pursuant to Section 6.2(d) or Section 6.2(e),

then EFI shall pay a termination payment in the amount of Cdn$3,000,000 as liquidated damages for the loss of EFI’s rights under this Agreement to Denison at the time of such termination in immediately available funds. EFI shall not be obligated to make more than one payment pursuant to this Section 6.3(b). EFI hereby acknowledges that the payment amount set out in this section is a payment of liquidated damages which are a genuine pre-estimate of the damages which Denison will suffer or incur as a result of the event giving rise to such damages and the resultant non-completion of the Arrangement and are not penalties. EFI hereby irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. Upon receipt of payment of the amount set out in this subsection by Denison, Denison shall have no further claim against EFI in respect of the failure to complete the Arrangement, provided that nothing herein shall preclude Denison from seeking injunctive relief to restrain any breach or threatened breach by EFI of any of its obligations hereunder or otherwise to obtain specific performance without the necessity of posting a bond or security in connection therewith as described in Section 8.4.

6.4 Reimbursement of Expenses

In the event that the Arrangement is not completed due to the condition in Section 5.3(h) not being satisfied as a result of KEPCO exercising its dissent rights contemplated by Section 4.1 of the Plan of Arrangement, then Denison shall reimburse EFI for its reasonable costs and expenses incurred in connection with the transactions contemplated by this Agreement, provided that Denison’s reimbursement obligation under this Section 6.4 shall not exceed Cdn$1,000,000.

7.1 Amendment

This Agreement may, at any time and from time to time before or after the holding of the Denison Meeting or EFI Meeting, be amended by mutual written agreement of the Parties without, subject to applicable Law, further notice to or authorization on the part of the Denison Shareholders or the EFI Shareholders, as the case may be, and any such amendment may, without limitation:

(a) change the time for the performance of any of the obligations or acts of any Party;

- 66 -

(c) waive compliance with or modify any of the covenants herein contained and waive or modify the performance of any of the obligations of any of the Parties; and

provided, however, that notwithstanding the foregoing: (i) following the Denison Meeting, the principal amount of the EFI Note and number of EFI Payment Shares shall not be amended (other than to reflect the EFI Share Consolidation) without the approval of the Denison Shareholders given in the same manner as required for the approval of the Arrangement or as may be ordered by the Court; (ii) following the EFI Meeting, the principal amount of the EFI Note and number of EFI Payment Shares shall not be amended (other than to reflect the EFI Share Consolidation) without the approval of the EFI Shareholders; and (iii) this Agreement and the Plan of Arrangement may be amended, in accordance with the Final Order but, in the event that the terms of the Final Order require any such amendment, the rights of the Parties under Section 5.2, Section 5.3, Section 6.1 and Section 7.2 hereof shall remain unaffected.

7.2 Mutual Understanding Regarding Amendments

(a) In addition to the Arrangement or at the request of a Party, the Parties will continue from and after the date hereof and through and including the Effective Date to use their respective reasonable commercial efforts to maximize present and future planning opportunities for Denison, the Denison Shareholders and EFI and the EFI Shareholders as and to the extent that the same shall not prejudice any Party or the shareholders thereof. The parties will ensure that such planning activities do not impede the progress of the Arrangement in any material way.

(b) The Parties agree that, if either Party proposes to the other Party any amendment to this Agreement or the Plan of Arrangement, both Parties will reasonably consider such amendment. The Parties further agree that if neither Party nor its respective shareholders will be materially prejudiced, and the completion of the Arrangement will not be delayed, by reason of any such amendment, then the Parties will co-operate to, subject to applicable Laws, effect the amendment or amendments.

ARTICLE 8—GENERAL

8.1 Denison Indemnity

(a) Indemnification by Denison. Denison shall indemnify and save harmless EFI and the Denison US Group from, and shall pay to EFI and the Denison US Group, on demand, the amount of any and all loss, liability, damage, cost, expense, charge, fine, penalty or assessment, suffered or incurred by EFI or the Denison US Group, directly resulting from or arising out of any act, omission or state of facts and any demand, action, investigation, inquiry, suit, proceeding, claim, assessment, judgment or settlement or compromise relating thereto (a “Claim”), including the costs and expenses of any action, suit, proceeding, investigation, inquiry, arbitration award, grievance, demand, assessment, judgment, settlement or compromise relating thereto (“Losses”), as a result of or arising in connection with:

(i) any inaccuracy of or any breach of any representation or warranty made by Denison in this Agreement or in any contract, agreement, instrument, certificate or other document delivered pursuant to this Agreement, whether or not EFI relied on or had knowledge of it;

- 67 -

(ii) the litigation relating to the contractor for the construction of tailings pond cell 4b at the White Mesa Mill, provided that Denison shall be entitled to receive the proceeds of any amounts received or recovered by Denison or by the Denison US Group as a result of a favourable ruling in favour of Denison or the Denison US Group in connection with such litigation;

(iii) any severance payments payable to employees of the Denison US Group who are entitled to receive such severance payments due to the change of control of DMHC resulting from the Transaction; and

The notice will specify with reasonable particularity (to the extent the information is available) the factual basis for the Claim and the amount of the Losses, if known. The failure to give, or delay in giving, a notice does not relieve Denison of its obligations except and only to the extent of any prejudice caused to Denison by that failure or delay.

(c) Investigation. Following receipt of a notice in respect of a Claim, Denison has 60 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of that investigation, EFI shall make available to Denison the information relied on by EFI or the Denison US Group to substantiate the Claim, together with such information as Denison may reasonably request. If the Parties agree at or prior to the expiry of this 60 day period (or prior to the expiry of any extension of this period agreed to by the Parties) as to the validity and amount of that Claim, Denison shall immediately pay to EFI or the Denison US Group the full amount as agreed to by the Parties of the Claim. For clarity, EFI is deemed to have incurred or suffered Losses as of and from the Effective Date as a consequence of any reduction in the value of the US Mining Division resulting from an inaccuracy or breach of any representation or warranty by Denison under this Agreement.

8.2 EFI Indemnity

(a) Indemnification by EFI. EFI shall indemnify and save harmless Denison from, and shall pay to Denison, on demand, the amount of any and all loss, liability, damage, cost, expense, charge, fine, penalty or assessment, suffered or incurred by Denison directly resulting from or arising out of any act, omission or state of facts and any Claim, including any Losses, as a result of or arising in connection with any inaccuracy of or any breach of any representation or warranty made by EFI in this Agreement or in any contract, agreement, instrument, certificate or other document delivered pursuant to this Agreement, whether or not Denison relied on or had knowledge of it.

(b) Notice of Claim. Denison, promptly on becoming aware of any circumstances that have given or could give rise to a Claim, shall give notice of those circumstances to EFI, The notice will specify with reasonable particularity (to the extent the information is available) the factual basis for the Claim and the amount of the Losses, if known. The failure to give, or delay in giving, a notice does not relieve EFI of its obligations except and only to the extent of any prejudice caused to EFI by that failure or delay.

- 68 -

(c) Investigation. Following receipt of a notice in respect of a Claim, EFI has 60 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of that investigation, Denison shall make available to EFI the information relied on by Denison to substantiate the Claim, together with such information as EFI may reasonably request. If the Parties agree at or prior to the expiry of this 60 day period (or prior to the expiry of any extension of this period agreed to by the Parties) as to the validity and amount of that Claim, EFI shall immediately pay to Denison the full amount as agreed to by the Parties of the Claim. For clarity, Denison is deemed to have incurred or suffered Losses as of and from the Effective Date as a consequence of any reduction in the value of the EFI Payment Shares resulting from an inaccuracy or breach of any representation or warranty by EFI under this Agreement.

8.4 Remedies

The Parties acknowledge and agree that an award of money damages may be inadequate for any breach of this Agreement by either Party or its representatives and advisors and that such breach may cause the non-breaching Party irreparable harm. Each Party agrees that it will not request that the court find that its breach or threatened breach has not or will not cause the other Party irreparable harm and neither Party will lend assistance to such a request. The Parties agree that, in the event of any such breach or threatened breach of this Agreement by one of the Parties, Denison (if EFI is the breaching Party) or EFI (if Denison is the breaching Party) will be entitled to seek equitable relief, including interim, interlocutory and permanent injunctive relief and specific performance. Each Party agrees that it will not take the position in court or otherwise that its breach or threatened breach has not or will not cause the other Party irreparable harm and neither Party will lend assistance to such position.

Each Party agrees that it will not request that the court require the Party or Parties seeking such relief to provide an undertaking as to damages or to post a bond or security as a condition of granting such relief. Without limiting the generality of the foregoing, the Parties acknowledge and agree that a mandatory order or other injunctive relief may be granted to enforce any negative covenant in this Agreement without the requirement to demonstrate irreparable harm or that the balance of convenience favours the Party seeking such relief. Subject to any other provision hereof including, without limitation, Section 8.4 hereof, such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available hereunder at law or in equity to each of the Parties.

8.5 Expenses

The Parties agree that, except for the termination payment provided for in Section 6.3, each Party shall be responsible for its own expenses including all out-of-pocket expenses incurred in connection with this Agreement and the Arrangement, the EFI Meeting, the Denison Meeting and the preparation and mailing of the EFI Proxy Circular and the Denison Proxy Circular, including legal and accounting fees, printing costs, financial advisor fees and all disbursements by advisors and that nothing in this Agreement shall be construed so as to prevent the payment of such expenses. The provisions of this Section 8.5 shall survive the termination of this Agreement.

- 70 -

8.6 Time of the Essence

Time shall be of the essence in this Agreement.

8.7 Entire Agreement

The Confidentiality Agreement and this Agreement, together with the agreements and other documents herein or therein referred to, constitute the entire agreement between the Parties pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, between the Parties with respect to the subject matter hereof. There are no representations, warranties, covenants or conditions with respect to the subject matter hereof except as contained herein. For the avoidance of doubt, this Agreement supersedes and replaces the Letter Agreement in its entirety.

8.8 Further Assurances

Each Party shall, from time to time, and at all times hereafter, at the request of the other of them, but without further consideration, do, or cause to be done, all such other acts and execute and deliver, or cause to be executed and delivered, all such further agreements, transfers, assurances, instruments or documents as shall be reasonably required in order to fully perform and carry out the terms and intent hereof including, without limitation, the Plan of Arrangement.

8.9 Governing Law

This Agreement shall be governed by, and be construed in accordance with, the laws of the Province of Ontario and the laws of Canada applicable therein but the reference to such laws shall not, by conflict of laws rules or otherwise, require the application of the law of any jurisdiction other than the Province of Ontario.

8.10 Execution in Counterparts

This Agreement may be executed in one or more counterparts, each of which shall conclusively be deemed to be an original and all such counterparts collectively shall be conclusively deemed to be one and the same. Delivery of an executed counterpart of the signature page to this Agreement by facsimile or electronic scanned copy shall be effective as delivery of a manually executed counterpart of this Agreement, and either Party delivering an executed counterpart of the signature page to this Agreement by facsimile or electronic scanned copy to the other Party shall thereafter also promptly deliver a manually executed original counterpart of this Agreement to such other Party, but the failure to deliver such manually executed original counterpart shall not affect the validity, enforceability or binding effect of this Agreement.

8.11 Waiver

No waiver or release by either Party shall be effective unless in writing and executed by the Party granting such waiver or release and any waiver or release shall affect only the matter, and the occurrence thereof, specifically identified and shall not extend to any other matter or occurrence. Waivers may only be granted upon compliance with the provisions governing amendments set forth in Section 7.1 hereof.

8.12 No Personal Liability

(a) No director or officer of EFI shall have any personal liability whatsoever (other than in the case of fraud or wilful misconduct) to Denison under this Agreement or any other document delivered in connection with this Agreement or the Arrangement by or on behalf of EFI.

- 71 -

(b) No director or officer of Denison shall have any personal liability whatsoever (other than in the case of fraud or wilful misconduct) to EFI under this Agreement or any other document delivered in connection with this Agreement or the Arrangement by or on behalf of Denison.

8.13 Enurement and Assignment

This Agreement shall enure to the benefit of the Parties and their respective successors and permitted assigns and shall be binding upon the Parties and their respective successors. This Agreement may not be assigned by either Party without the prior written consent of each of the other Parties.

8.14 United States Tax Considerations

(a) The Parties contemplate that this Agreement, together with the Plan of Arrangement annexed hereto, shall not constitute a plan to effectuate a partial liquidation of Denison within the meaning of Sections 302(b)(4) and 302(e) of the Code.

(b) Promptly upon signing this Agreement, Denison will apply for a withholding certificate from the United States Internal Revenue Service under United States Treasury Regulation section 1.1445-3(b) stating that no withholding on the Purchase and Sale Transaction or any other transaction described in the Plan of Arrangement is required under section 1445(a) of the Code. In reliance on representations in this Agreement and on Denison’s agreement to apply for a withholding certificate, EFI agrees to not reduce the EFI Note by the amount of withholding otherwise required under section 1445(a) of the Code. Denison will indemnify EFI for any amount that should have been withheld under section 1445(a) of the Code if the Internal Revenue Service fails to issue a withholding certificate or issues a withholding certificate that does not completely exempt Denison from withholding. Denison will provide EFI with a copy of the application and will forward all related correspondence to EFI immediately upon receipt. For purposes of the indemnification under this Section 8.14(b), Section 3.4 shall not apply to the representations contained in Section 3.2(bb)(vii) and Section 3.2(bb)(viii), and such representations and warranties shall survive the execution and delivery of this Agreement and the completion of the Arrangement and shall continue for a period of ending on the earlier of the receipt of the withholding certificate from the United States Internal Revenue Service showing no withholding is required or 24 months from the Effective Date.

- 72 -

(c) The Parties agree that the sole consideration for the Purchased Shares is the Share Consideration, allocated 70% to the DMHC Common Shares and 30% to the White Canyon Ordinary Shares and no portion of the EFI Note or the EFI Payment Shares shall constitute consideration for the sale of the Purchased Shares. The Parties agree to characterize for all tax purposes the sale by Denison and the purchase by EFI of (i) the Purchased Shares in consideration of the payment of the Share Consideration and (ii) the Acquired Debt in consideration of the issuance of the EFI Note as a sale in which gain or loss is recognized. Neither Party shall take a position on any tax return inconsistent with such sale treatment except as required by a taxing authority and each Party hereby indemnifies the other for any loss realized by such other party arising out of a Party taking a tax position inconsistent with this Section 8.14(c) unless required by a taxing authority, in which case there will be no indemnification by either Party.

(d) Notwithstanding any other provisions of this Agreement, if, five days before the Effective Time, the amount of the Acquired Debt exceeds the estimated value of the EFI Payment Shares (the difference being the “Acquired Debt Excess”), Denison will contribute a portion of the Acquired Debt to DMHC in an amount equal to the Acquired Debt Excess in exchange for newly issued equity securities of DMHC; provided, however, that Denison will not be required to make this contribution if doing so would give rise to additional tax to Denison under the Tax Act.

ARTICLE 2—ARRANGEMENT AGREEMENT

2.1 Arrangement Agreement

This Plan of Arrangement is made pursuant to, and is subject to the provisions of, the Arrangement Agreement, except in respect of the sequence of the steps comprising the Arrangement, which shall occur in the order set forth herein.

ARTICLE 3—ARRANGEMENT

3.1 Arrangement

Commencing at the Effective Time, the following shall occur and shall be deemed to occur sequentially in the following order at separate moments in time without any further act or formality:

(a) Denison and EFI shall complete the Purchase and Sale Transaction pursuant to which Denison shall sell to EFI, and EFI shall purchase from Denison (i) all of the Purchased Shares in consideration for payment of the Share Consideration to Denison and (ii) all of the Acquired Debt in consideration for the issuance of the EFI Note to Denison;

(b) each Denison Share held by a Dissenting Shareholder shall be deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all liens, claims and encumbrances, to Denison and Denison shall thereupon be obliged to pay the amount therefor determined and payable in accordance with Article 4 hereof, and the name of such holder shall be removed from the central securities register as a holder of Denison Shares and such Denison Shares so transferred to Denison shall thereupon be cancelled;

(c) in the course of a reorganization of capital:

(i) the authorized share capital of Denison shall be reorganized and altered by:

A. renaming and re-designating all of the issued and unissued Denison Shares as Class A common shares (the “Denison Class A Shares”) which shares shall have the same rights and restrictions as the Denison Shares except that each Denison Class A Share shall be entitled to two votes at any meeting of the Denison Shareholders, and

B. creating an unlimited number of common shares without par value (the “New Common Shares”) with rights, privileges, restrictions and conditions identical to the Denison Shares;

(ii) Denison’s Articles of Incorporation shall be amended to reflect the alterations in section 3.1(c)(i);

(iii) pursuant to the reorganization, each issued and outstanding Denison Class A Share shall be exchanged for one New Common Share and an assignment by Denison of that portion of the principal amount of the EFI Note determined by dividing the fair market value of the EFI Note by the number of Denison Class A Shares outstanding;

- A4 -

(iv) the Denison Class A Shares, none of which will be allocated and issued once the steps referred to in section 3.1(c)(iii) are completed, shall be cancelled and the authorized capital of Denison shall be changed by deleting the Denison Class A Shares as a class of shares of Denison;

(v) the amount added to the stated capital of the New Common Shares shall be the excess, if any, of (1) the paid-up capital (as that term is used for the purposes of the Tax Act) of the Denison Shares (other than the Denison Shares held by the Dissenting Shareholders) immediately prior to the Effective Time, less (2) the principal amount of the EFI Note; and the stated capital of the Denison Class A Shares shall, for greater certainty, be nil;

(vi) Denison’s Articles of Incorporation shall be amended to reflect the alterations in section 3.1(c)(iv); and

(d) pursuant to the terms of the EFI Note, EFI will repay the EFI Note by issuing the EFI Payment Shares to the Denison Shareholders in full and final satisfaction of the EFI Note. No fractional EFI Common Shares shall be issued. In the event that the repayment of the EFI Note would otherwise result in the issuance to a Denison Shareholder of a number of EFI Common Shares which is not a whole number, the number of EFI Common Shares to be issued to such Denison Shareholder shall be rounded down to the nearest whole number.

3.2 Post-Effective Date Procedures

(a) On or promptly after the Effective Date, EFI shall deliver or arrange to be delivered to the Depositary certificates representing the EFI Payment Shares to be issued to the Denison Shareholders on the repayment of the EFI Note and in accordance with the provisions of the Arrangement, which certificates shall be held by the Depositary as agent and nominee for such Denison Shareholders for distribution to such Denison Shareholders in accordance with the provisions of Article 5 hereof.

(b) Subject to the provisions of Article 5 hereof, Denison Shareholders (other than Dissenting Shareholders) shall be entitled to receive delivery of the certificates representing the EFI Common Shares to which they are entitled pursuant to the Arrangement.

3.3 Deemed Fully Paid and Non-Assessable Shares.

All New Common Shares and EFI Payment Shares issued pursuant hereto shall be deemed to be validly issued and outstanding as fully paid and non-assessable shares for all purposes of the OBCA.

3.4 Supplementary Actions.

Notwithstanding that the transactions and events set out herein shall occur and shall be deemed to occur in the order set out in this Plan of Arrangement without any further act or formality, each of the parties to the Arrangement Agreement shall make, do and execute, or cause to be made, done and executed, all such further acts, deeds, agreements, transfers, assurances, instruments or documents as may reasonably be required by either of them in order further to document or evidence any of the transactions or events set out herein.

- A5 -

ARTICLE 4—DISSENT RIGHTS

4.1 Dissent Rights

Holders of Denison Shares may exercise rights of dissent (the “Dissent Right”) pursuant to and in the manner set forth under the OBCA, as modified by the Interim Order (the “Dissent Procedures”), with respect to Denison Shares in connection with the Arrangement, provided that holders who exercise such rights of dissent and who:

(a) are ultimately entitled to be paid fair value for their Denison Shares, which fair value shall be the fair value of the Denison Shares immediately before the passing by the holders of the Denison Shares of the resolution approving the Arrangement, shall be paid an amount equal to such fair value by Denison; or

(b) are ultimately not entitled, for any reason, to be paid fair value for their Denison Shares shall be deemed to have participated in the Arrangement, commencing at the Effective Time, on the same basis as a non-dissenting holder of Denison Shares and shall be entitled to receive only the consideration contemplated in Section 3.1 hereof that such holder would have received pursuant to the Arrangement if such holder had not exercised Dissent Rights,

but in no case shall EFI, Denison or any other person be required to recognize holders of Denison Shares who exercise Dissent Rights as holders of Denison Shares after the time that is immediately prior to the Effective Time, and the names of such holders of Denison Shares who exercise Dissent Rights shall be deleted from the central securities register as holders of Denison Shares at the Effective Time.

ARTICLE 5—CERTIFICATES

5.1 Denison Class A Shares

Recognizing that the Denison Shares shall be renamed and re-designated as Denison Class A Shares pursuant to subsection 3.1(c)(i)(A) and that the Denison Class A Shares shall be exchanged partially for New Common Shares pursuant to subsection 3.1(c)(iii), Denison shall not issue replacement share certificates representing the Denison Class A Shares.

5.2 EFI Payment Shares

On or immediately prior to the Effective Time, EFI shall deliver or arrange to be delivered to the Depositary certificates representing the EFI Payment Shares for distribution to the Denison Shareholders, together with an irrevocable direction to distribute and transfer the EFI Payment Shares to the Denison Shareholders in accordance with this Plan of Arrangement.

5.3 New Common Shares

From and after the Effective Date, share certificates representing Denison Shares not deemed to have been cancelled pursuant to Article 4 shall for all purposes be deemed to be share certificates representing New Common Shares, and no new share certificates shall be issued with respect to the New Common Shares issued in connection with the Arrangement.

- A6 -

5.4 Interim Period

Any Denison Shares traded after the Distribution Record Date will represent New Common Shares as of the Effective Date and shall not carry any rights to receive a pro rata portion of the EFI Note or EFI Payment Shares.

5.5 Withholding Rights

Denison and the Depositary shall be entitled to deduct and withhold from all dividends or other distributions otherwise payable to any Denison Shareholder such amounts as Denison or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986, as amended, or any provision of any applicable federal, provincial, state, local or foreign tax law or treaty, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Denison Shareholder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority.

5.6 Legality of Distribution of EFI Payment Shares

Notwithstanding anything else in this Plan of Arrangement, if it appears to EFI that it would be contrary to applicable law to issue EFI Payment Shares in repayment of the EFI Note pursuant to the Arrangement to a person that is not a resident of Canada or the United States, the EFI Payment Shares that otherwise would be issued, as the case may be, to that person will be issued, as the case may be, and delivered to the Depositary for sale of the EFI Payment Shares by the Depositary on behalf of that person. The EFI Payment Shares delivered to the Depositary will be pooled and sold as soon as practicable after the Effective Date, on such dates and at such prices as the Depositary determines in its sole discretion. The Depositary shall not be obligated to seek or obtain a minimum price for any of the EFI Payment Shares sold by it. Each such person will receive a pro rata share of the cash proceeds from the sale of the EFI Payment Shares sold by the Depositary (less commissions, other reasonable expenses incurred in connection with the sale of the EFI Payment Shares and any amount withheld in respect of applicable taxes) in lieu of EFI Payment Shares. The payment of the net proceeds will be subject to Section 5.5. None of EFI, Denison or the Depositary will be liable for any loss arising out of any such sales.

- A7 -

- 4 -

Assumptions and Limitations

With the approval and agreement of the Board of Directors, we have relied upon and assumed, without assuming responsibility or liability for independent verification, the completeness, accuracy and fair presentation of all financial information, business plans, financial analyses, forecasts and other information, data, advice, opinions and representations obtained by us from public sources, or provided to us by the Corporation or Energy Fuels, their respective subsidiaries, directors, officers, associates, affiliates, consultants, advisors and representatives relating to the Corporation, Energy Fuels, their respective subsidiaries, associates and affiliates, and to the Transaction. The Fairness Opinion is conditional upon such completeness, accuracy and fair presentation. We have not been requested to or, subject to the exercise of professional judgment, attempted to verify independently the completeness, accuracy or fair presentation of any such information, data, advice, opinions and representations. We have relied upon the due diligence review of Energy Fuels conducted by the Corporation and its external consultants and advisors. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Corporation or Energy Fuels under any provincial or federal laws relating to bankruptcy, insolvency or similar matters. In addition, we have not assumed any obligation to conduct any physical inspection of the properties or the facilities of the Corporation or Energy Fuels.

With respect to any financial analyses, forecasts, projections, estimates and/or budgets provided to Haywood Securities and used in its analyses, Haywood Securities notes that projecting future results of any company is inherently subject to uncertainty. Haywood Securities has assumed, however, that such financial analyses, forecasts, projections, estimates and/or budgets were prepared using the assumptions identified therein and that such assumptions reflect the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Corporation and Energy Fuels to which such financial analyses, forecasts, projections, estimates and/or budgets relate. We express no view as to such financial analyses, forecasts, projections, estimates and/or budgets or the assumptions on which they were based.

We have also assumed that the Transaction will have the tax consequences described in discussions with, and materials furnished to us by, representatives of the Corporation, and that the other transactions contemplated by the Arrangement Agreement will be consummated as described in the Arrangement Agreement. In preparing the Fairness Opinion, we have made several assumptions, including that all of the conditions required to complete the Transaction will be met and that the disclosure provided in the Circular with respect to the Corporation, Energy Fuels and their respective subsidiaries and affiliates and the Transaction will be accurate in all material respects.

We have relied as to all legal matters relevant to rendering our opinion upon advice of counsel. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Corporation or Energy Fuels or on the contemplated benefits of the Transaction.

The Fairness Opinion is rendered as at the date hereof and on the basis of securities markets, economic and general business and financial conditions prevailing as at the date hereof and the conditions and prospects, financial and otherwise, of the Corporation as they are reflected in the information provided by the Corporation and as they were represented to us in our discussions with the management of the Corporation. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. We are expressing no opinion herein as to the price at which the Shares will trade at any future time. In our analyses and in connection with the preparation of the Fairness Opinion, we made numerous assumptions with respect to industry performance, general business, market and economic conditions and other matters, many of which are beyond the control of Haywood Securities and any party involved in the Transaction.

- 5 -

We have not been asked to prepare and have not prepared a valuation of the Corporation, the US Mining Division, or Energy Fuels or any of the securities or assets thereof and our opinion should not be construed as a “formal valuation” (within the meaning of Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions).

This Fairness Opinion is provided for the use of the Board of Directors of the Corporation only and may not be disclosed, referred or communicated to, or relied upon by, any third party without our prior written approval. Haywood Securities consents to the inclusion of this Fairness Opinion in the Circular. Haywood Securities disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Fairness Opinion which may come or be brought to the attention of Haywood Securities after the date hereof. Without limiting the foregoing, in the event that there is any material change in any fact or matter affecting the Fairness Opinion after the date hereof, Haywood Securities reserves the right to change, modify or withdraw the Fairness Opinion.

Haywood Securities believes that its analyses must be considered as a whole and that selecting portions of the analyses or the factors considered by it, without considering all factors and analyses together, could create a misleading view of the process underlying this Fairness Opinion. The preparation of an opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Any attempt to do so could lead to undue emphasis on any particular factor or analysis.

Fairness Conclusion

Based on and subject to the foregoing and such other factors as Haywood Securities considered relevant, Haywood Securities is of the opinion that, as of the date hereof, the consideration to be received by the common shareholders of the Corporation in connection with the Transaction is fair, from a financial point of view, to such common shareholders of the Corporation.

Yours truly,

HAYWOOD SECURITIES INC.

Note Regarding Forward-Looking Information

Certain statements contained in this Appendix G, and in certain documents incorporated by reference into this Appendix G, constitute “forward-looking information” within the meaning of applicable Canadian Securities Laws and “forward-looking statements” within the meaning of applicable US Securities Laws (collectively, “forward-looking information”). All forward-looking information is based on the current expectations, estimates, projections, beliefs and assumptions of Denison and Energy Fuels based on information available at the time the information was provided and in light of their experience and perception of historical trends. The use of any of the words “anticipate”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “should”, “believe”, “plan”, “intend”, “design”, “target”, “undertake”, “view”, “indicate”, “maintain”, “explore”, “schedule”, “objective”, “strategy”, “likely”, “potential” and similar words and expressions are intended to identify forward-looking information. By its nature, forward-looking information involves known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking information. Denison and Energy Fuels believe the expectations reflected in its forward-looking information are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking information included in, or incorporated by reference into, this Appendix G should not be unduly relied upon. This information speaks only as of the date of the Information Circular or as of the date specified in the documents incorporated by reference into this Appendix G, as the case may be.

In particular, this Appendix G, and the documents incorporated by reference herein, contains forward-looking information pertaining to, among other things: Energy Fuels’ strategies and objectives, both generally and specifically in respect of the proposed Piñon Ridge Mill facility and Energy Fuels’ Colorado, Utah, Arizona, New Mexico, Wyoming and Canadian properties; the potential for the development of the Piñon Ridge Mill; the outcome of litigation; the potential for the expansion of current mineral resources and mineral reserves; the timing of decisions and costs of exploration programs with respect to, and the issuance of the necessary permits and authorizations required for Energy Fuels’ ongoing exploration programs on its properties; Energy Fuels’ estimates of the quality and quantity of the mineral resources and mineral reserves at its mineral properties; Denison’s estimates of the quality and quantity of the resources at its mineral properties forming part of the US Mining Division; the timing and cost of the planned future exploration programs at the Sheep Mountain Project and the timing of the receipt of results therefrom; Energy Fuels’ future cash requirements; general business, market and economic conditions; Energy Fuels’ ability to meet its financial obligations as they come due, and to be able to raise the necessary funds to continue operations; Energy Fuels’ ongoing business plan; expectations of Energy Fuels respecting integration risks; information about the US Mining Division and the effects of the Arrangement, including but not limited to, the business, operations and financial performance of Energy Fuels following completion of the Arrangement; and information about the EFI Share Consolidation, including but not limited to, Energy Fuels’ business, operations and financial performance following completion of the EFI Share Consolidation.

Various assumptions were used in drawing the conclusions or making the forecasts and projections contained in the forward-looking information throughout this Information Circular. These factors and assumptions include, but are not limited to: the ability of Energy Fuels following the Arrangement to realize the enhanced growth opportunities currently anticipated, in particular with respect to the US Mining Division; the market, level and volatility of the price of commodities in general, and uranium and vanadium in particular; conditions in the financial markets generally; general business and economic conditions; the completion of the Arrangement and the EFI Share Consolidation; the proposed timeline for the construction of the Piñon Ridge Mill and anticipated production dates; Energy Fuels’ ability to secure the necessary consulting, drilling and related services and supplies on favourable terms in connection with its ongoing and planned exploration programs, especially with respect to the Sheep Mountain Property; Energy Fuels’ ability to attract and retain key staff; the accuracy of Energy Fuels’ and Denison’s mineral resource and mineral reserves estimates (including with respect to size and grade) and the geological, operational and price assumptions on which these are based; the timing of the ability to commence and complete the planned work at the Sheep Mountain Property; the anticipated terms of the consents, permits and authorizations necessary to carry out the planned exploration and development programs at Energy Fuels’ current properties and with respect to the US Mining Division and Energy Fuels’ ability to comply with such terms on a safe and cost-effective basis; and the ongoing relations of Energy Fuels with the underlying optionors and/or lessors and the applicable regulatory agencies.

Actual results could differ materially from those anticipated in the forward-looking information provided as a result of the material risks and uncertainties including, without limitation: the Arrangement and/or the EFI Share Consolidation may not be completed in the manner or on the timelines anticipated, or at all; Denison and/or Energy Fuels may be unable to satisfy the conditions of the Arrangement including obtaining the required consents, permits or approvals, including Shareholder, TSX and NYSE MKT approval and the Final Order of

G-2

the Court approving the Arrangement; the occurrence of an event, change or other circumstance that could give rise to the termination of the Arrangement Agreement; Energy Fuels may fail to realize the anticipated synergies and benefits of the Purchase and Sale Transaction; volatility in market prices for commodities; volatility in exchange rates for the Canadian dollar relative to other world currencies; changes in general economic, market and business conditions in Canada, North America, and worldwide; actions by governmental or regulatory authorities including changes in income tax laws; global financial conditions; volatility in market prices for uranium and vanadium; the risk that upon completion of the Arrangement and/or the EFI Share Consolidation the market value of EFI Shares will be different from the value at the time the Arrangement was agreed and the EFI Share Consolidation was approved; the ability of Energy Fuels to access capital required to carry out its intended business plans and operations; changes in foreign currency exchange rates and interest rates; liabilities inherent in mining operations; uncertainties associated with estimating mineral reserves and mineral resources and production; uncertainty as to environmental, reclamation and decommissioning liabilities; risks related to the ability of Energy Fuels to identify one or more economic deposits on its current properties, variations in the nature, quality and quantity of any mineral deposits that may be located on its properties; failure to obtain industry partner, government and other third party consents and approvals, when required; delays in obtaining permits and licences for development properties; competition for, among other things, capital, acquisitions of mineral reserves, undeveloped lands and skilled personnel; public resistance to nuclear energy or uranium mining; uranium industry competition and international trade restrictions; incorrect assessments of the value of acquisitions; property title risk; geological, technical and processing problems; the ability of Energy Fuels to meet its obligations to its creditors; actions taken by regulatory authorities with respect to mining activities the potential influence of, or reliance upon, its business partners; the adequacy of insurance coverage; compliance with environmental laws; litigation risk; construction risk; maintaining safe work sites; project risks; and the impact of environmental issues, including climate change.

Readers are cautioned that the foregoing lists are not exhaustive. The information contained in the Information Circular, including the information provided under the heading “Risk Factors” therein and the information provided under the heading “Risk Factors” in this Appendix G and in the documents incorporated by reference in this Appendix G, discusses certain of the items identified above and their impact more fully and identifies additional factors and uncertainties that could affect the performance and operating results of Energy Fuels and the US Mining Division. Readers are urged to carefully consider those factors and the other information contained or incorporated by reference in this Information Circular. The impact of any one risk, uncertainty or other factor on specific forward-looking information is not determinable with certainty as these factors are interdependent and the future course of action by management of Energy Fuels will depend upon the assessment of all information at that time.

Denison and Energy Fuels have included the above summary of assumptions and risks related to forward-looking information provided in this Appendix G in order to provide Shareholders with a more complete perspective on Energy Fuels’ current and future business and operations, the US Mining Division and the future business and operations of Energy Fuels and such information may not be appropriate for other purposes. The actual results, performance or achievements of Energy Fuels could differ materially form those expressed in, or implied by, this forward-looking information and, accordingly, no assurance can be given that any of the events anticipated by the forward-looking information will transpire or occur, or if any of them do so, the benefits that Energy Fuels or Shareholders will derive therefrom.

Denison and Energy Fuels do not undertake any obligation to publicly update or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as may be required pursuant to applicable laws. Any forward-looking information contained or incorporated by reference herein is expressly qualified by this cautionary statement.

Intercorporate Relationships

The following chart shows, in a simplified manner, the intercorporate relationships between Energy Fuels and its Material Subsidiaries as at the date hereof.

Business of Energy Fuels

Energy Fuels is a Toronto, Ontario based uranium and vanadium exploration and mine development company with projects located in the states of Colorado, Utah, Arizona and New Mexico. Energy Fuels’ mission has been to build a fully integrated uranium and vanadium production company through exploration, development, mining, milling and sales, primarily targeting immediately economic uranium properties on the Colorado Plateau (Colorado and Utah) and in the broader western United States. In addition, Energy Fuels has a corporate strategy of consolidating prospective uranium properties within the western United States and has been actively seeking suitable acquisition candidates.

Energy Fuels currently has two permitted mines in its mineral property portfolio. The Whirlwind Mine is located in the northern Uravan mineral belt approximately four miles southwest of Gateway, Colorado. The Energy Queen Mine is located in the mineral belt near the town of La Sal, Utah. The permit for the Energy Queen Mine was transferred by Denison Mines (USA) Corp., a wholly-owned subsidiary of DMHC, to Energy Fuels in January, 2008.

G-5

With about 61,000 acres of highly prospective uranium and vanadium properties located in the states of Colorado, Utah, Arizona, Wyoming and New Mexico, as well as exploration properties in Athabasca Basin in Saskatchewan totalling approximately 32,000 additional acres, Energy Fuels has a full pipeline of additional development prospects. Energy Fuels, through its wholly-owned subsidiaries, has assembled this property portfolio along with a first class management team, including highly skilled technical mining and milling professionals.

On March 1, 2012, Energy Fuels announced an updated preliminary feasibility study for its Sheep Mountain Project. The study contemplates the concurrent development of the underground and open pit deposits for a 15 year mine life. This option generates a pre-tax internal rate of return (“IRR”) of 42% and a net present value (“NPV”) of US$201 million, at a 7% discount rate and a US$65/lb long term U₃O₈ price. This option has an expected initial capital expenditure requirement of US$109 million and operational expenditure of US$32.31 per lb recovered. The Sheep Mountain project is currently at an advanced stage of permitting. Production is expected to commence in 2015, with a peak production rate of 1.5 million lbs U₃O₈ per year.

The Sheep Mountain Project contains an Indicated Mineral Resource of 12,895,000 tons at an average grade of 0.12% eU₃O ₈ (30,285,000 lbs eU₃O₈ ). This figure includes Probable Reserves of 7,453,000 tons at an average grade of 0.123% eU₃O₈ (18,365,000 lbs eU₃O₈). Energy Fuels’ Colorado Plateau properties additionally contain Measured Mineral Resources and Indicated Mineral Resources of 1,960,000 tons at an average grade of 0.24% eU₃O₈ and 0.89% V₂O₅ (9,321,800 lbs eU₃O₈ and 35,017,000 lbs V₂O₅), comprised of 824,600 tons Measured Mineral Resources at an average grade of 0.24% eU₃O₈ and 0.89% V₂O₅ (3,722,100 lbs eU₃O₈ and 21,546,700 lbs V₂O₅) and 1,135,400 tons Indicated Mineral Resources at an average grade of 0.24% eU₃O₈ and 0.89% V₂O₅ (5,599,700 lbs eU₃O₈ and 13,470,300 lbs V₂O₅).

Management of Energy Fuels will continue to pursue and evaluate strategic options, including partnerships, joint ventures and acquisition opportunities that enhance shareholder value and which fit within Energy Fuels’ mineral resource development strategy. In the past, funding for exploration and development operations has been obtained through equity offerings. Future operations (and the ability to meet mineral property option commitments) are dependent upon Energy Fuels’ continuing ability to finance expenditures and achieve profitable operations. Energy Fuels continues to evaluate other funding sources such as debt, joint ventures, non-core asset divestitures, strategic partnerships and project financing to finance its growth.

Recent Developments

The following is a summary of recent developments since the Energy Fuels AIF was filed on December 17, 2011.

On February 29, 2012, Energy Fuels and Titan completed the Titan Arrangement whereby Titan was merged into Energy Fuels. On February 29, 2012, Titan became a wholly-owned subsidiary of Energy Fuels. Energy Fuels issued an aggregate of 89,063,997 EFI Shares in exchange for all of the 130,976,467 issued and outstanding common shares of Titan (“Titan Shares”) on the basis of 0.68 of an EFI Share for each whole Titan Share. In addition, 14, 926,881 EFI Shares were reserved for issuance upon exercise of warrants issued by Titan. As a part of the Titan Arrangement, Sheldon Inwentash, Richard Patricio and Larry Goldberg were added to the EFI Board. The Titan Arrangement added over 30 million lbs of eU₃O₈ to Energy Fuels’ portfolio from the Sheep Mountain Project located in Freemont County, Wyoming. At full production, the Sheep Mountain Project is anticipated to produce approximately 15 million lbs of U₃O₈ per year. It is anticipated that all permits for the Sheep Mountain Project will be obtained by 2015. These include an environmental impact statement and plan of operations approved by the U.S. Nuclear Regulatory Commission. Further details on the Titan Arrangement may be found in Energy Fuels’ public disclosure documents filed under Energy Fuels’ profile on SEDAR.

On March 1, 2012, Energy Fuels announced the results of a prefeasibility study on the Sheep Mountain Project (the “Sheep Mountain PFS”). The Sheep Mountain PFS was posted on SEDAR on April 13, 2012. The Sheep Mountain Project is an existing mine with both open and underground components. The U₃O₈ will be extracted in a heap leach recovery facility. The Sheep Mountain PFS analyzed three development scenarios for the Sheep Mountain Project (assuming a price of $65/lb of U₃O₈) as follows:

• Open Pit and Underground – Concurrent Start: Under this scenario, production from both the open pit and underground components will begin simultaneously. This scenario has an IRR of 42%, an NPV of US$200.6 million (at 7%), initial capital expenditures of US$109.4 million and operating expenses of US$32.31/lb U₃O₈ .

G-6

• Open Pit and Underground – Concurrent End: Under this scenario, production would initially be from the open pit and production from the underground component would begin later so that both open pit and underground mining would end at the same time. This scenario has an IRR of 35%, an NPV of US$173.5 million (at 7%), initial capital expenditures of US$118.5 million and operating expenses of US$32.31/lb U₃O₈.

• Open Pit Only: Under this scenario, production would occur only in the open pit, with no underground mining. This scenario has an IRR of 33%, an NPV of US$96.0 million (at 7%), initial capital expenditures of US$60.8 million and operating expenses of US$31.31/lb U₃O₈.

On April 16, 2012, Energy Fuels and Denison announced the signing of the Letter Agreement.

Energy Fuels is the holder of a radioactive materials license issued by the State of Colorado for the Piñon Ridge Mill (the “Piñon License”). Since the spring of 2011, the Piñon License has been subject to a legal challenge from a non-governmental organization and two municipalities located about 60 miles from the proposed project. The challenge is being heard in State District Court in Denver, Colorado. If built, the Piñon Ridge Mill would be the second operating conventional uranium mill in the United States (the other being White Mesa). The Piñon Ridge Mill is being designed and permitted at a capacity of 500 tons per day. Since December 17, 2011, all of the parties to the challenge have submitted each of their briefs to the court. The parties are awaiting decisions by the court on various motions, including a request for oral arguments made by Energy Fuels and the Colorado Department of Public Health and Environment in their reply briefs. A decision on this case is expected by the summer or fall of 2012.

THE US MINING DIVISION

Following the completion of the Arrangement, Energy Fuels will own and operate the US Mining Division. The following provides an overview of the material attributes of the US Mining Division.

Operations

White Mesa

White Mesa is a fully licensed uranium mill with a vanadium co-product recovery circuit located in southeastern Utah near the Colorado Plateau District (as defined below), the Henry Mountains Complex, the Arizona Strip and the White Canyon District. White Mesa is approximately six miles south of the city of Blanding, Utah. Access is by US Highway 191.

Construction of White Mesa began in 1979, and conventionally-mined uranium/vanadium ore was first processed in May, 1980. The mill uses sulphuric acid leaching and a solvent extraction recovery process to extract and recover uranium and vanadium. The mill has been operated on a campaign basis since its initial start-up due to variable uranium market conditions.

In addition to the conventional ore circuit, a circuit for processing certain types of alternate feed materials was built in 2009. This circuit enables the mill to process both conventional ore and alternate feed materials simultaneously. See “The US Mining Division – Operations – Alternate Feed Materials”.

White Mesa is licensed to process an average of 2,000 tons of ore per day and to produce up to 8.0 million pounds of U₃O₈ per year. In full operation, White Mesa employs approximately 150 people.

Current Condition and Operating Status

In late 2006, Denison began a program to refurbish White Mesa. The refurbishment program included the purchase of mobile equipment, restoration of the vanadium roasting, fusion and packaging circuits, replacement of major pumps and component drives, modernization of the mill’s instrumentation and process control systems, and completion of the relining of tailings cell 4A (“Cell 4A”). The total cost of the refurbishment program was approximately US$31.0 million and was completed in 2008.

G-12

In April, 2008, White Mesa began processing uranium/vanadium conventional ore and producing uranium concentrate. Production of vanadium began in July, 2008 after completion of the refurbishment of the vanadium circuit. Processing of conventional ore continued through the end of March, 2009 when the mill was shut down for approximately 30 days for relining of the semi-autogenous grinding mill and other critical maintenance activities. Processing of conventional ore recommenced near the end of April; however, conventional ore processing was discontinued near the end of May for the remainder of 2009 due to a decline in uranium prices. White Mesa began processing conventional ore again in March, 2010 and continued through to June, 2011. Conventional ore processing recommenced in November, 2011. During 2011, White Mesa processed approximately 110,000 tons of uranium/vanadium ore from the Colorado Plateau, 24,800 tons of ore from Arizona 1, 32,000 tons of ore from Daneros and 5,800 tons of ore from the Ore Purchase Program (defined below). See “The US Mining Division – Operations – Ore Purchase and Toll Milling”.

Processing of two different alternate feed materials occurred in 2011 using the separate alternate feed circuit built in 2009. In addition, two other alternate feed materials were processed using the conventional ore circuit in October, 2011.

Production at White Mesa over the past five years is shown below.

White Mesa processed conventional ore during the first two months of 2012, and conventional ore processing will resume in August, 2012. Conventional ore from the Colorado Plateau, Daneros and Arizona 1 will be processed. Processing of four different alternate feed materials is expected to continue throughout 2012. Two of the alternate feed materials will be processed using the alternate feed circuit, while two other materials will be processed using the conventional ore circuit during the period when there is no conventional ore processing planned. Energy Fuels anticipates continuing with the implementation of Denison’s plans for White Mesa, but increasing production over time as mine development and market conditions warrant.

White Mesa Licence

White Mesa operates under a Radioactive Materials Licence issued by the State of Utah (the “Utah Radioactive License”). The licence came up for renewal on March 31, 2007. A Licence Renewal Application was submitted to the Utah Department of Environmental Quality (“UDEQ”), Division of Radiation Control (“DRC”) on February 28, 2007. The licence renewal process is underway. The licence remains in effect in its current form during the licence renewal process.

Tailings Disposal

Synthetic lined cells are used to contain tailings and, in one case, solutions for evaporation. As each tailings cell is filled with tailings, the water is drawn off and pumped to the evaporation pond and the tailings solids allowed to dry. When a cell reaches final capacity, reclamation will begin with the placement of interim cover over the tailings. Additional cells are excavated, and the overburden is used to reclaim previous cells. In this way, there is an ongoing reclamation process.

Denison completed a refurbishment of Cell 4A in August, 2008 and received an operating permit from the DRC in September, 2008. Cell 4A has been in operation since that time and provides approximately 2.0 million tons of tailings capacity.

To ensure sufficient volume for tailings and surface area for tailings solution evaporation, Denison began the licensing process for tailings cell 4B (“Cell 4B”) in 2009. Construction of Cell 4B was completed in December, 2010 and final approval to begin use of Cell 4B was received in January, 2011. Cell 4B is currently being used for additional evaporation capacity and provides an additional approximately 2.0 million tons of tailings capacity.

Environmental

Denison detected some chloroform contamination at the White Mesa site that appears to have resulted from the operation of a temporary laboratory facility that was located at the site prior to and during the construction of the mill facility and from septic drain fields that were used for laboratory and sanitary wastes prior to construction of the mill’s tailings cells. Elevated concentrations of nitrate and chloride were also observed in some monitoring wells at the mill site in 2008, a number of which were up-gradient of the mill’s tailings cells. In addition, the mill has reported consecutive exceedances of Groundwater Compliance Limits (“GWCLs”) under White Mesa’s Groundwater Discharge Permit (a “GWDP”) for several constituents in several wells, and there is a decreasing trend in pH in a number of wells across the White Mesa site that have caused the pH in a number of compliance monitoring wells to have dropped below their GWCLs. These exceedances and pH trends include wells that are upgradient of the White Mesa facilities and are currently being evaluated. See “US Mining Division – Environmental and Safety Matters”.

Alternate Feed Materials

The Utah Radioactive Licence gives Denison the right to process other uranium-bearing materials known as “alternate feed materials” pursuant to an alternate feed guidance adopted by the US Nuclear Regulatory Commission (“NRC”). Alternate feed materials are uranium-bearing materials, which usually are classified as waste products by generators of the materials. Requiring a routine amendment to its licence for each different alternate feed, Denison can process these uranium-bearing materials and recover uranium, in some cases, at a fraction of the cost of processing conventional ore, alone or together with other valuable metals such as niobium, tantalum and zirconium. In other cases, generators of alternate feed materials are willing to pay a recycling fee to Denison to process these materials to recover uranium and then dispose of the remaining by-product in White Mesa’s licensed tailings cells, rather than directly disposing of the materials at a disposal site. By working with Denison and taking the recycling approach, suppliers of alternate feed materials can significantly reduce their remediation costs, as there are only a limited number of disposal sites for uranium-bearing materials in the United States.

To date, White Mesa has received 15 licence amendments, authorizing the mill to process 18 different alternate feed materials. Of these amendments, nine involve the processing of feeds provided by nuclear fuel cycle facilities and private industry and one has involved the processing of material from the United States Department of Energy (“DOE”). These ten feed materials have been relatively high in uranium content and relatively low in volume. The remaining five amendments have been to allow White Mesa to process uranium-bearing soils from former defence sites, known as FUSRAP sites, which were being remediated by the US Army Corps of Engineers. These materials are typically relatively low in uranium content but relatively high in volume.

US Mines

The US Mining Division is currently involved in four mining districts: the Colorado Plateau District; the Henry Mountains District; the White Canyon District and the Arizona Strip. The mines are shown in the figure below and are described in further detail below.

G-14

Colorado Plateau District

The Colorado Plateau District is an area encompassing approximately 20,000 square miles and straddles the border of southeastern Utah and southwestern Colorado (the “Colorado Plateau District”). Denison’s principal mining complexes in the Colorado Plateau District consist of the La Sal, Van 4, Sunday, and East Canyon (Rim) zones. The bulk of the mineral deposits in the Colorado Plateau District are contained in three areas: the Sunday Mine complex, which includes the Sunday/St. Jude, West Sunday, Topaz and Carnation mines (the “Sunday Mine Complex”); the La Sal complex, which includes the La Sal, Beaver and Pandora mines (the “La Sal Complex”); and the East Canyon Area, which includes the Rim mine. All of these areas have developed permitted mines either in operation or on standby. The mines are located approximately 65 to 100 miles northwest of White Mesa. Haulage of the ore from the mines to White Mesa is along county and state highways.

G-15

Colorado Plateau

The Uravan mineral belt in the Colorado Plateau District has a lengthy mining history, with the first shipment of mined materials made to France in 1898. Vanadium was the focus of production from the 1920’s to the early 1940’s. World War II brought increased attention to the uranium mineralization in the area of the Uravan mineral belt, and by the 1950s this district was one of the world’s foremost producers of both uranium and vanadium. Historical production has yielded an overall V₂O₅ to U₃O₈ ratio of 5.79:1. Production continued more or less uninterrupted until 1984 when low uranium prices forced the closure of all operations. Production resumed in 1987 when vanadium prices spiked, but ceased in 1990. Except for limited production in 1998 and 1999, all operations were shut down until 2006 when several of the mines re-opened.

The uranium/vanadium deposits in the Colorado Plateau District were deposited as both alluvial fans by braided streams and meander belts of larger streams. The shape and size of the mineralized seams are extremely variable. As a result, exploration and mining have historically involved conducting exploration to find a seam and then merely following its erratic path, with little exploration other than development drilling in the course of following the seam. The unusual nature of these deposits has therefore traditionally resulted in a limited amount of financial resources being dedicated to delineate mineral resources or mineral reserves prior to mining.

Mining properties in the Colorado Plateau District are held by a combination of unpatented claims and leases with third parties. On the leased properties, there are uranium royalties payable ranging from 2.5% to 10.0% and vanadium royalties payable ranging from 4% to 12.5%. It should be noted that these royalties are only payable on ore recovered from specific claim areas and do not necessarily apply to the entire deposit.

Operations

Sunday/St. Jude, Topaz, West Sunday, La Sal and Pandora are all accessed by declines from the surface. Beaver is accessed by a shaft and is connected underground to Pandora and La Sal. Rim is a combination of a shaft and decline access but at the present time is only accessed through the decline. Sunday/St. Jude, West Sunday, Pandora, Rim and Beaver are mature operating mines with extensive underground workings. Topaz is relatively new with the initial development drift completed in 2007. The mining method is random room and pillar in which no set pillar pattern is established but rather both the size of the rooms and the pillars are variable and are defined by the deposit geometry. A typical room is about 20 feet wide with pillars as small as 12 feet square in highly mined areas.

G-16

The limited height of the mineral deposit means that mining in this area must be quite selective in order to maintain a satisfactory production grade. This is done by closely following the mineralized zones and by using the technique of “split shooting” wherein the mineral deposit and waste are blasted separately in a two-stage operation.

In June, 2006, Denison restarted mining activity in the United States with the re-opening of several mines in the Colorado Plateau District. Over a 12 month period, Denison re-opened five mines in the Colorado Plateau District. In late 2008, Denison began rehabilitation of Beaver which began shipping ore in February, 2009.

As a result of declining uranium prices, Denison placed Topaz on standby in January, 2009. In March, 2009, Denison placed Rim and Sunday/St. Jude on standby, followed by West Sunday in October, 2009. These mines have been maintained so that they can be restarted with minimal effort. Beaver and Pandora are the only two operating mines in the Colorado Plateau District at the present time.

No Mineral Reserve or Mineral Resource estimates have been prepared in accordance with NI 43-101 for any of these mines. The uranium grades shown above are based on probe grades taken when the ore arrives at White Mesa. The vanadium grades are based on historical uranium/vanadium ratios.

In addition to the mine production detailed above, a number of low grade stockpiles from the Colorado Plateau Mines were shipped to White Mesa. In 2007 a total of 7,973 tons were shipped to White Mesa, grading 0.08% U₃O₈ and 0.43% V₂O₅ . In 2008, a total of 6,801 tons were shipped, grading 0.08% U₃O₈ and 0.39% V₂O_5, and in 2010, 213 tons, grading 0.09% U₃O₈ and 0.50% V₂O₅ were shipped. There was no low grade material shipped in 2009 or 2011.

Permitting

Pandora, Beaver, La Sal and Rim are all permitted for current operations. At all of the Colorado Plateau Mines, air permits have been obtained or are in the process of being obtained. Stormwater as well as spill prevention and pollution control plans were also updated for all Colorado Plateau Mines. These plans require regular monitoring and reporting.

G-17

Under Colorado laws, the Colorado Division of Reclamation, Mining and Safety (“CDRMS”) has determined that all uranium mines are Designated Mining Operations (“DMO”). If a mine is determined to be a DMO there is a requirement that it submit an Environmental Protection Plan (“EPP”). An EPP must identify the methods the operator will utilize for the protection of human health, wildlife, property and the environment from the potential toxic or acid forming material associated with the operations. An EPP must be submitted to CDRMS for review and, after approval by CDRMS, will be subject to public comment.

Representative samples were collected of ore, waste rock, and soils surrounding the mine sites. These samples were analysed, and arsenic was the only constituent considered to be of possible concern. Studies were conducted on the mechanisms of arsenic liberation, transport, and possible exposure to the environment and biota. The surface and ground water environments were also investigated under the DMO assessment. Groundwater sampling wells were installed in West Sunday to obtain samples of undisturbed groundwater and to assess possible impacts to water in contact with mine workings and the atmosphere.

Upon joint consultation with CDRMS, plans were developed to collect the necessary data and perform characterization testing and prepare assessments of toxic substance exposures and transport necessary for preparation of an EPP for the Sunday Mine Complex.

The EPP for the Sunday Mine Complex and Van 4 was filed in 2009 (the “Sunday Mine EPP”). The Sunday Mine EPP is in final review by CDRMS and upon approval groundwater monitoring wells will be installed, and a commitment to install ore pad liners will be finalized.

In February, 2009, the U.S. Bureau of Land Management (“BLM”) approved an amended Plan of Operations (“PO”) for Topaz incorporating all of the mines in the Sunday Mine Complex. The BLM made a Finding of No Significant Impact (“FONSI”), as a result of its Environmental Assessment (“EA”) of the project. CDRMS had already approved the conversion of the Topaz 110 permit (a permit for a mine with less than 10 acres of surface disturbance) to a 112 permit (a permit for a mine with greater than 10 acres of surface disturbance), allowing additional disturbance as needed for development and production at Topaz.

An appeal was made on the FONSI resulting in the state director of BLM remanding the decision record back to the local field office for further study and analysis (the “Remand Decision”). The data collection requirements mandated by the Remand Decision have been fulfilled and the reports of findings have been submitted. Upon finalization of the EPP approval by CDRMS, a dump leachate monitoring well will be installed at Topaz to address concerns raised by the remand and to fulfill EPP requirements.

As a result of routine permit applications for additional ventilation raises and exploration drilling for the La Sal Complex, the BLM, United States Forest Service (“USFS”) and State of Utah Department of Oil and Gas and Mining (“UDOGM”) requested that the PO (the “La Sal PO”) and Utah Mine Permit (the “La Sal Permit”) for the La Sal Complex be amended to include the current operating plans. Materials required for the formal amendment of the La Sal PO and La Sal Permit have been submitted and are under review by the BLM, USFS and UDOGM. The amendment involves the preparation of an EA and will proceed through public notice and a BLM decision record. Current operations have not been affected during this amendment process, but new disturbance activities, such as installation of new vent shafts and exploration drilling (on public lands), have been deferred until the amendment process is complete. The amendment process is expected to be completed and a decision record issued by the end of 2012.

Henry Mountains Complex

The Henry Mountains Complex is one contiguous property located in eastern Garfield County, Utah, 15 to 20 miles north of Bullfrog Basin Marina on Lake Powell and approximately 40 air miles south of Hanksville, Utah. It is situated three miles west of Utah State Highway 276. The Henry Mountains Complex includes the Bullfrog property on the north end of the property, hosting the Indian Bench, Copper Bench and Southwest uranium deposits (“Bullfrog”), and the Tony M property (the “Tony M Property”) located on the south end of the property, hosting the Tony M deposit and mine (“Tony M”). See “The US Mining Division – Mineral Properties – Henry Mountains Complex”.

G-18

The Bullfrog property was extensively explored by Exxon Minerals Company (“Exxon”) and Atlas Minerals & Chemicals Inc. in the period from 1974 to 1990. Development of Tony M began in September, 1977, and nearly 17 miles of underground workings were developed prior to suspension of mining in 1985, following which the mine was allowed to flood. Tony M is located approximately 117 miles west of White Mesa. Ore haulage to the mill is along county and state highways.

Denison acquired the Bullfrog property when it purchased substantially all of the uranium producing assets of Energy Fuels Ltd., Energy Fuels Exploration Company and Energy Fuels Nuclear, Inc. (collectively, “EFN”) in 1997. In February, 2005, Denison acquired Tony M, bringing it under common ownership with Bullfrog. Prior to 2005, all exploration, mine development and related activities for the two properties were conducted independently.

The Henry Mountains Complex is comprised of 202 unpatented BLM mining claims and one 640 acre Utah State Mineral Lease (the “Tony M Lease”). Seventeen of the claims, comprising a portion of Tony M, are subject to an escalating annual advance minimum royalty based on the uranium spot price, and a 4% yellowcake royalty, less taxes and certain other deductions. There is also a vanadium production royalty which is a 2% gross royalty less certain deductions. The advance minimum royalties are deductible against the uranium and vanadium royalties payable. The Tony M Lease has an annual rental of US$640 and is subject to royalties set by the State of Utah including: an escalating annual advance minimum royalty based on the uranium spot price, a uranium royalty of 8% of gross value less certain deductions; and a vanadium royalty of 4% of gross value less certain deductions. Annual holding costs for Tony M (including advance royalties to the State of Utah, private parties and BLM claim maintenance fees) will total approximately $577,805 in 2012. The advance royalties on the Tony M Lease are only deductible against the uranium and vanadium royalties paid within the same year.

Operations

Upon receipt of an initial exploration permit, Denison engaged Dynatec Mining Corporation (“Dynatec”) as its mine contractor for Tony M. In May, 2007, Dynatec began limited rehabilitation work on the existing Tony M workings.

An operating permit for Tony M was received in September, 2007, allowing Dynatec to shift from rehabilitation work to mining of the Tony M deposit. As of the end of 2007, 9,368 tons of ore, grading 0.10% U₃O₈ had been shipped to White Mesa from Tony M.

In addition to re-opening the mine, Denison also constructed a number of surface facilities including a power generation station, compressor station, fuel storage facilities, maintenance building, offices and employee shower facilities. An evaporation pond, originally constructed when Tony M was in operation in the 1980’s and which is used for storage and evaporation of mine water, was reconstructed to allow for dewatering of the mine.

In 2008, 87,421 tons, grading 0.15% U₃O₈ , was shipped to White Mesa, as well as 64,755 tons of ore from the historic stockpiles, grading 0.11% U₃O₈ . In November, 2008, Denison placed Tony M on temporary stand-by due to high operating costs and the weakening of the uranium spot price. Shipping of ore from the historic stockpiles continued after the mine was placed on stand-by.

G-19

In March, 2009, shipping of the historic ore stockpile to White Mesa was completed, shipping 29,737 tons of ore, grading 0.11% U₃O₈.

Tony M remains on care and maintenance, and dewatering activities are continuing so that mining operations can resume quickly, when uranium prices reach viable levels.

Permitting

A Record of Decision and approved PO was received in September, 2007 for the Henry Mountain Complex which comprises both Tony M and Bullfrog.

The PO was challenged and on November 21, 2007, the BLM State Director issued a decision vacating the previously issued permit and remanded the case in order that an EA for the PO for Tony M (the “Tony M PO”) could be amended and a new Record of Decision issued. A new Record of Decision was issued by the BLM on November 23, 2007 approving the Tony M PO. The new decision was again appealed. The Utah State Director issued a decision denying the appeal and upholding the Tony M PO on February 19, 2008.

A PO for phase two development has been filed with the BLM and UDOGM. Phase two activities include the addition of ventilation shafts, upgrading of the shaft and site access road, installation of a production shaft and expansion of the mine water evaporation reservoir. Phase two permitting efforts continue with the BLM and UDOGM.

White Canyon

The White Canyon District is located in southeastern Utah in the Colorado Plateau (the “White Canyon District”). The White Canyon District generally encompasses the local geographic areas of Red, White and Fry Canyons, and Elk Ridge along State Highway 95 between Blanding and Hite, Utah. Energy Fuels will hold a 100% interest in various groups of mining claims and Utah State Leases comprising its White Canyon District holdings, including Daneros and adjoining historical mine sites which can be developed in conjunction with the Daneros project. Denison’s holdings in the White Canyon District also include exploration properties.

Major uranium deposits in the east-central Colorado Plateau occur principally in two fluvial sandstone sequences. The older is located at or near the base of the Upper Triassic Chinle Formation and the other occurs in the Late Jurassic Salt Wash Member of the Morrison Formation. Nearly all of the mineral deposits in the White Canyon District occur in fluvial channel deposits of the Shinarump Member, the basal member of the Chinle Formation.

The Shinarump Member consists of predominantly trough-crossbedded, coarse-grained sandstone and minor gray, carbonaceous mudstone and is interpreted as a valley-fill sequence overlain by deposits of a braided stream system. Uranium mineralization appears to be related to low-energy depositional environments in that uranium is localized in fluvial sandstones that lie beneath organic-rich lacustrine-marsh mudstones and carbonaceous delta-front sediments. The reducing environment preserved in these facies played an important role in the localization of uranium.

Uranium deposits consist of closely-spaced, lenticular mineral pods which are generally concordant with bedding in paleochannel sediments. Single mineral pods range from a few feet to a few hundred feet in length and from less than one to more than ten feet in thickness. Deposits range in size from a few tons to more than 600,000 tons. Deposits in the Shinarump Member generally have low vanadium content, and are therefore not processed for vanadium recovery. Historical production from the White Canyon District exceeds 11 million pounds U₃O₈ .

Between 1975 and 1985, Utah Power & Light (“UP&L”) conducted several phases of drilling in the White Canyon District near Daneros. Following 1985, the properties were idle and little or no exploration activity took place in the White Canyon District. From 2005 to 2007, predecessors of White Canyon began acquiring properties with known historic mineral deposits in the White Canyon District. In June, 2007, after consolidating a portfolio of properties and prospects, White Canyon initiated confirmation and definition drilling at Daneros. Based on the success of this initial drilling, 38 more holes were drilled in 2008, which provided the basis for mineral resource estimates relied upon by White Canyon to commence mine development work at Daneros.

G-20

Daneros is located 4.8 miles from Fry Canyon, Utah and is accessed via Radium King Road for approximately 14 miles, which is maintained by San Juan County. Daneros was developed and placed into active production by Utah Energy Corporation (“UEC”), the US operating entity for White Canyon at the time. The shipping distance from Daneros to White Mesa is 65 miles along county roads and state highways.

In January, 2010, Denison entered into a toll milling agreement with UEC, which was then a wholly-owned subsidiary of White Canyon. See “US Mining Division – Operations – Ore Purchase and Toll Milling”.

In June, 2011, Denison completed the White Canyon Acquisition. The assets acquired in the White Canyon Acquisition included all of White Canyon’s mining claims and mineral leases in Utah, including 547 claims and five Utah State Leases, totalling about 5,670 hectares (14,000 acres), all in southeastern Utah. The land holdings in the White Canyon District include 341 unpatented mining claims and two Utah State Leases, in total about 3,000 hectares (7,400 acres). The mining claims are maintained by making annual payments of US$140 per claim, and the Utah State Leases generally cost US$1 per acre annually.

A number of the properties acquired in the White Canyon Acquisition bear production royalties. Claims hosting Daneros are subject to royalties ranging between 15% of “market value” of the ore and 2.5% of gross proceeds. The exploration properties also have royalties in some cases, including Utah State Leases which provide for royalties of 8% on uranium and 4% on vanadium.

Operations

UEC gathered the necessary environmental data and submitted applications for approvals to open an underground mine at Daneros. A PO was submitted to the BLM and was approved in May, 2009 (the “Daneros PO”), following which UEC commenced active mine development, including driving a decline into the main deposit at Daneros. The first loads of ore from Daneros were delivered to White Mesa in December, 2009, and a toll milling campaign was conducted in the second half of 2010. Daneros is currently operated by Denison (through the use of contract miners) and ore from the mine is delivered to White Mesa and processed for Denison’s account.

The initial mine plan at Daneros involved driving twin declines (with the second decline for emergency escape and ventilation) into the center of the Daneros deposit and developing away from the entry point. Random room and pillar mining is employed, as is typical for the deposits in the local region. Mining utilizes rubber tired loaders and small trucks to transport ore to the surface, where it is loaded into over-the-road trucks, covered by a secure tarpaulin and transported to White Mesa.

The ore production from Daneros for 2010 and 2011 is shown below:

When White Canyon owned Daneros it prepared mineral resource estimates in accordance with the requirements of the Code for Reporting of Mineral Resources and Ore Reserves of Australasian Joint Ore Reserves Committee (the “JORC Code”) in August, 2010. Denison disclosed this information as a historical estimate under NI 43-101. See “US Mining Division – Mineral Properties – Historical Estimates – White Canyon Historical Estimates”. Upon completion of the Arrangement, Energy Fuels intends to prepare Mineral Resource estimates in accordance with the requirements of NI 43-101 in due course for Daneros.

G-21

Permitting

The primary permits required for mining operations at Daneros include a mine permit issued by UDOGM and the Daneros PO approved by the BLM. The Daneros PO required document preparation and public notice of an EA. The permits obtained by UEC were for the initial stage of operations and contemplated eventual expansion of the mining operations, with the inclusion of additional surface area for support facilities. Daneros does not discharge any water, so no discharge permit is required.

An appeal of the approval of the Daneros PO was denied by the Utah BLM State office, and is currently under appeal to the Department of Interior Board of Land Appeals.

Following the White Canyon Acquisition, work commenced to modify the Daneros PO to expand the footprint of mine operations to support continued production from Daneros and adjoining properties. Expansion of surface facilities at Daneros will also require an Air Permit from UDEQ, Division of Air Quality. Daneros will also become subject to requirements for monitoring and reporting of radon emissions from the mine and its vents; this program (National Emissions Standards for Hazardous Air Pollutants (“NESHAP”)) is also administered by the UDEQ, Division of Air Quality. Daneros is in compliance with all data collection and reporting requirements under stormwater and spill prevention programs.

Arizona Strip

The Arizona Strip is an area largely bounded on the north by the Arizona/Utah state line; on the east by the Colorado River and Marble Canyon; on the west by the Grand Wash Cliffs; and on the south by a midpoint between the city of Flagstaff, Arizona and the Grand Canyon. The area encompasses approximately 13,000 square miles.

Denison owns four developed and partially developed mines in the Arizona Strip, being Arizona 1, Canyon, Pinenut and Kanab North, all of which had been shut down since the 1980s. In February, 2007, Denison purchased from Pathfinder Mines Corporation (“Pathfinder”) five additional uranium deposits in the Arizona Strip: EZ1, EZ2, DB 1, WHAT and Moonshine Springs. Denison recommenced development work on Arizona 1 in April, 2007, and restarted mining operations in November, 2009. Development work on the Pinenut mine commenced in November, 2010.

Since 1980, when mine development first began at the Arizona Strip it has produced in excess of 19 million pounds of uranium from seven mines, each of which was owned and operated by EFN. Of these mines five are mined out and have been reclaimed.

Ore from the Arizona Strip mines is hauled by truck from the mine sites to White Mesa. Arizona 1 and Pinenut are approximately 307 road miles, and Canyon is 325 road miles from White Mesa.

G-22

Arizona Strip

The Arizona Strip mines are held by unpatented BLM claims, except for Moonshine Springs, which is held by a combination of mineral claims and a mineral lease. There is a 3.5% yellowcake royalty on Canyon.

Operations

In the mid-1980s, the shaft at Arizona 1 was sunk approximately 1,200 feet below surface before activity at the mine was shut down due to depressed uranium prices. The original target depth was 1,600 feet in order to reach the bottom of the mineral deposit. Denison decided to ramp down from the bottom of the existing shaft rather than deepen the shaft to access the lower parts of the mineral deposit.

Work began on the rehabilitation of the shaft in mid-2007. Denison engaged J.S. Redpath Corporation (“Redpath”) to work on rehabilitation of the surface facilities, the hoist and headframe and the underground workings. The rehabilitation of the shaft, underground development, sinking of an internal raise and the sinking of a ventilation shaft were completed in September, 2008. Due to ongoing delays in receipt of an air quality permit, Redpath was demobilized from the site at that time. The air quality permit for Arizona 1 was received in September, 2009. See “Permitting” below.

Arizona 1 is being mined using a combination of long hole and shrinkage stopping methods at a mining rate of up to 300 tons per day, four days per week. In 2010, Arizona 1 produced approximately 21,500 tons at an average grade of 0.56% U₃O₈ and in 2011 produced 39,900 tons at an average grade of 0.66% U₃O₈ . The mine is projected to operate through to the fourth quarter of 2012 unless additional ore resources can be identified through further drilling.

In November, 2009, a Complaint for Declaratory and Injunctive Relief against the Secretary of the Interior and the BLM was filed. See “US Mining Division – Legal and Regulatory Proceedings”. At this time, this legal action has not impacted the operations at Arizona 1.

In November, 2010, a production decision was made on Pinenut. Pinenut was partially developed in the late 1980’s and a limited amount of selective mining was conducted. A shaft was sunk to a depth of 1,350 feet and a high grade pod was mined in late summer 1988, yielding 25,500 tons, grading 1.03% U₃O₈, containing 526,000 pounds. Following extraction of the high grade pod, EFN placed the mine on standby in 1989.

G-23

Expansion of the stormwater storage pond and rehabilitation of the surface facilities were completed in 2011 and the rehabilitation of the mine workings is ongoing. First ore production is expected in 2012. Uranium production is expected to total approximately 936,000 pounds U₃O₈ , of which 526,000 pounds is expected to be produced in 2013, with the balance to be produced in 2014. Energy Fuels anticipates continuing with the implementation of Denison’s plan for Pinenut.

Canyon is proceeding through permitting based on the March, 2012 approval of the Denison Board to proceed with development. Kanab North remains on care and maintenance and a closure plan is being prepared for this mine site. Energy Fuels anticipates continuing with the implementation of Denison’s plans for Canyon and Kanab North.

Permitting

Prior to 2009, Arizona 1 had received all required permits, with the exception of an Air Quality Permit which is required under new Arizona requirements. The air quality permit was issued by the Arizona Department of Environmental Quality (“ADEQ”), Department of Air Quality after a period of public comment in September, 2009.

In 1992, Arizona updated its laws relating to groundwater issues, requiring that an aquifer protection permit be obtained for each mine. The Arizona 1 mine has an individual aquifer protection permit. Denison prepared documents applying for groundwater general permits for the on-site ponds, ore storage and development waste storage pads and stormwater collection for Pinenut and Canyon. In September, 2009, the groundwater general permits were received for the stormwater storage ponds for the Pinenut and Canyon mines. Air Quality Permits for Pinenut, Canyon and EZ1/EZ2 were issued by ADEQ in March, 2011.

At Pinenut approval of the operation from the EPA under NESHAP has been obtained. All other permits for operation are approved and in place for both operations.

The BLM has accepted the PO for EZ1 and EZ2 as complete and review is underway. A mineral examination by BLM is in progress and scoping for an Environmental Impact Statement is expected to commence in late 2012 or early 2013.

In July, 2009, the BLM issued a Notice of Proposed Withdrawal (“2009 Notice”). See “US Mining Division – Government Regulation – Land Tenure”. In January, 2012, the withdrawal proposed in the 2009 Notice was implemented. To confirm Energy Fuels’ rights to proceed with development and mining on its existing valid rights, mineral examinations will be prepared by the USFS for Canyon, and by the BLM for the EZ Complex and potentially DB 1 as well. Upon confirmation of a valid existing right at Canyon, commencement of site work is contemplated in early to mid-2012.

Ore Purchase and Toll Milling

In July, 2007, Denison initiated an ore purchase program to provide additional mill feed for White Mesa (the “Ore Purchase Program”). A schedule listing the price to be paid per ton is currently posted on Denison’s website at www.denisonmines.com from time to time. Denison adjusts the buying schedule periodically in response to changing factors such as uranium and vanadium prices, milling cost and uranium and vanadium recoveries. Energy Fuels intends to continue the Ore Purchase Program.

Under the Ore Purchase Program White Mesa received: 2,423 tons in 2008, at an average grade of 0.19% U₃O₈ and 1.0% V₂O₅ ; 9,077 tons in 2009, at an average grade of 0.32% U₃O₈ and 0.66% V₂O₅ from 11 different mines; 110 tons in 2010 and 589 tons in 2011.

In January, 2010, Denison entered into a toll milling agreement with UEC, under which White Canyon transported up to 55,000 tons per year of ore produced from White Canyon’s mines to White Mesa for processing. White Canyon paid Denison the operating costs to mill its ore, a capital charge, plus a toll milling fee per ton of ore, which was linked to the long-term uranium price. During 2010, Denison toll milled approximately 39,300 tons of ore for White Canyon producing approximately 204,000 pounds U₃O₈. The toll milling agreement was terminated pursuant to the White Canyon Acquisition.

See “US Mining Division – Mineral Properties – Henry Mountains Complex”.

Henry Mountains Complex

The Henry Mountains Complex is currently 100% indirectly owned by Denison, and is comprised of the Bullfrog property, hosting Indian Bench and Copper Bench and the Tony M property, hosting Southwest and Tony M.

On October 17, 2006, Denison filed on the SEDAR website at www.sedar.com an independent technical report entitled “Technical Report on the Henry Mountains Complex Uranium Project, Utah, USA.” prepared by Scott Wilson RPA in accordance with the requirements of NI 43-101 with respect to its Henry Mountains Complex (“Henry Mountains Technical Report”). This report provided current estimates for Indian Bench, Copper Bench and Southwest and a historical resource estimate for Tony M.

On March 26, 2009, Denison received an independent review of current mineral resource estimates for Tony M and Southwest on the Henry Mountains Complex prepared by Scott Wilson RPA in accordance with NI 43-101 (“Henry Mountains Tony M – Southwest Technical Report”).

G-26

Property Description and Location

The Henry Mountains Complex is one contiguous property located in eastern Garfield County, Utah, 15 to 20 miles north of Bullfrog Basin Marina on Lake Powell and approximately 40 air miles south of the town of Hanksville, Utah. It is situated three miles west of Utah State Highway 276. The Henry Mountains Complex includes the Bullfrog property located to the north and the Tony M property located to the south.

The Henry Mountains Complex is comprised of 202 unpatented BLM mining claims totalling approximately 3,665 acres and the Tony M Lease. The surface rights are owned by the federal government and administered by the BLM, with the exception of the Tony M Lease which has associated state surface rights. Seventeen of the claims, comprising a portion of the Tony M property, are subject to an escalating annual advance minimum royalty based on the uranium spot price, and a 4% yellowcake royalty, less taxes and certain other deductions. There is also a vanadium production royalty which is a 2% gross royalty less certain deductions. The Tony M Lease has an annual rental of US$640 and is subject to royalties set by Utah including: an escalating annual advance minimum royalty based on the uranium spot price; a uranium royalty of 8% of gross value less certain deductions; and a vanadium royalty of 4% of gross value less certain deductions.

Accessibility, Climate, Local Resources, Infrastructure and Physiography

Road access to the Henry Mountains Complex is by paved Highway 276, running between Hanksville and Bullfrog Basin Marina, Utah. A gravel road, maintained by Garfield County and extending west from Highway 276, provides access to the southern end of the property. An unimproved county road passes by the portal of Tony M and extends northerly across the property. A network of unimproved, dirt exploration roads provide access over the property except for areas of rugged terrain. The Bullfrog Basin Marina airstrip is located approximately 15 miles south of the Henry Mountains Complex. The Henry Mountains Complex is located in a relatively remote area of Utah, and the infrastructure is limited. The distance to White Mesa is 117 miles.

Relief over the combined Bullfrog and Tony M properties is about 2,250 feet. The elevation ranges from 4,550 feet above sea level at the portal of Tony M, near the southern end of the property, to 6,800 feet above sea level over the northern end of the property. The terrain is typical canyon lands topography, with some areas deeply dissected by gullies and headwalls of canyons and the rest consisting of gently sloping gravel benches covering the northern half of the properties.

History

The Bullfrog property was initially explored by Exxon, while the Tony M property was explored and developed by Plateau Resources Inc. (“Plateau”), at that time a subsidiary of Consumers Power of Michigan.

Denison acquired Bullfrog when it purchased substantially all of the uranium producing assets of EFN in 1997. In February, 2005, Denison acquired Tony M, thus bringing it under common ownership with Bullfrog.

Prior to 2005, all exploration, mine development, and related activities for the two properties were conducted independently. Bullfrog and Tony M are therefore discussed separately, except where correlations and comparisons are made.

Bullfrog Property

Exxon conducted reconnaissance in the area of Bullfrog in 1974 and 1975, and then staked its first claims in the area in 1975 and 1976. A first phase drilling program conducted in 1977 resulted in the discovery of Southwest. Additional claims were subsequently staked and drilling was continued by Exxon. Several uranium and vanadium zones were discovered in the Southwest, and Copper Bench and Indian Bench areas. With the declining uranium markets of the early 1980s, Exxon prepared a prefeasibility report and then discontinued development of the property.

From July, 1982 to July, 1983, 112 drill holes were completed by Atlas Corp., under a purchase option with Exxon, delineating the Southwest and Copper Bench deposits on approximately 100 foot centres. From July, 1983 to March, 1984, a core drilling program was completed throughout the Bullfrog property with 133 rotary drill holes to delineate the Indian Bench deposit on approximately 200 foot centres.

G-27

In late 1992, EFN purchased the Bullfrog property from Exxon and conducted a geologic review and internal economic analysis of the property. Denison became the owner of the Bullfrog property in 1997.

Tony M Property

Exploration drilling in the area around Shootaring Canyon was initiated by Plateau during 1976 in the vicinity of outcropping uranium mineralization. In February, 1977, drilling commenced in what was to become Tony M. More than 2,000 rotary drill holes totalling about one million feet were drilled.

Development of Tony M started in September, 1977. By mid-1984, nearly 17 miles of underground workings had been developed in Tony M. During development of the Tony M entryways and crosscuts, a total of 237,441 tons of material with an average grade of 0.121% U₃O₈ was extracted and stockpiled.

In 1989, 30 to 40 rotary holes were drilled to delineate zones of high grade uranium mineralization.

Geological Setting

The Henry Mountains Complex uranium deposits occur within the Salt Wash Member of the Morrison Formation, located within the Colorado Plateau. The Morrison Formation is a complex fluvial deposit of Late Jurassic age that occupies an area of approximately 600,000 square miles, including parts of 13 western states and small portions of three Canadian provinces, far to the north and east of the boundary of the Colorado Plateau.

The Bullfrog and Tony M deposits consist of two extensive elongated, tabular zones containing a large concentration of mineralization. Together the Southwest deposit of the Bullfrog property and the Tony M deposit extend for a distance of about three miles along a north-south trend and have a maximum width of about one-half mile. The larger Indian Bench and Copper Bench deposits within the Bullfrog property extend about 3.5 miles along a northwesterly trend.

Mineralization in the Bullfrog property deposits occurs over three stratigraphic zones of the Salt Wash Member of the Morrison Formation, while mineralization at the Tony M property occurs over four zones. The Southwest deposit (like most of the adjacent Tony M property) occurs in the lowermost 35 feet to 40 feet of the Salt Wash Member sandstone. Mineralization forming the Copper Bench and Indian Bench deposits occurs between about 60 feet and 100 feet above the base of the Salt Wash Member.

The depth below the surface to the base of the three deposits ranges from about 475 feet (Southwest deposit) to nearly 1,100 feet in both the Copper Bench and Indian Bench deposits.

Exploration

Surface drilling using rotary tricone technology, together with radiometric gamma logging, was the primary exploration method used to discover and delineate uranium on the Bullfrog and Tony M properties.

During development of Tony M, Plateau also conducted an intensive mine geology program to collect detailed information on the occurrence of uranium, including its thickness, grade, and lateral extent. This was done through geological mapping, together with face and rib scanning, as well as gamma probing of short up and down holes extending to about eight feet. Probing was also done using long-hole drilling to test target zones up to about 150 feet from mine openings. The results of this program were recorded on a systematic set of cross sections through Tony M, developed at a scale of 10 feet to the inch. Scott Wilson RPA did not have access to the detailed information collected underground in Tony M.

Denison carried out no work on the Bullfrog and Tony M properties, with the exception of a review of available data and critical evaluation, until the end of 2005, when Denison initiated certain activities including underground reconnaissance and permitting on the Bullfrog and Tony M properties. See “US Mining Division – Operations – US Mines – Henry Mountains Complex”.

G-28

Mineralization

The uranium/vanadium mineralization in the Henry Mountains Complex is similar to deposits observed elsewhere in the Colorado Plateau. It occurs as intragranular disseminations within the fluvial sand facies of the Salt Wash Member. It also forms coatings on sand grains and associated organic masses. Coffinite is the dominant primary uranium mineral in the mineralized horizons, with uraninite occurring in only trace amounts.

Vanadium occurs as montroseite (hydrous vanadium oxide) and vanadium chlorite in primary mineralized zones located below the water table. Above the water table to the south, vanadium chlorite is absent, while montroseite and a suite of secondary uranium/vanadium minerals are present.

Drilling

Bullfrog Property

Most of the drilling done on the Southwest, Copper Bench, and Indian Bench deposits on the Bullfrog property was conducted by rotary drilling using a tricone bit. Additional drilling was done to collect core samples.

The Indian Bench deposit is delineated by drilling on approximately 200 foot centres, while the Southwest and Copper Bench deposits were drilled on 100 foot centres. In some areas, the rugged terrain made access difficult, resulting in an irregular drill pattern. A total of 2,232 drill holes were completed on the Bullfrog property.

The mineralization is approximately horizontal on the Bullfrog property, so vertical holes provide a reliable estimate of the thickness of the deposits.

Tony M Property

In February, 1977, drilling commenced in the Tony M deposit. Plateau drilled more than 2,000 rotary drill holes totalling about 1.0 million feet. The holes were drilled using rotary tricone technology. The rugged terrain over much of the Tony M property made drilling access difficult, resulting in an irregular drill pattern. The drilling includes 24 core holes. The core holes provided samples of the mineralized zone for chemical and amenability testing and to determine geologic and engineering properties of the mineralized zone.

Sampling and Analysis

Bullfrog Property

Downhole gamma logging of surface holes was done on the Bullfrog property. Standard logging suites included radiometric gamma, resistivity and self potential measurements, supplemented by neutron-neutron surveys for dry holes. Deviation surveys were conducted for most of the holes.

Assays of samples from core drilling were collected by company geologists and submitted to various commercial labs for analysis. Results of these analyses were compared to eU₃O₈ values from gamma logs to evaluate radiometric equilibrium, logging tool performance, and validity of gamma logging.

Metallurgical testing included leach amenability studies, settling, and filtration tests.

Mineral resource estimates for the Bullfrog property are based on the eU₃O₈% gamma log conversion values used to identify the mineralized zone, its thickness and calculate an average grade. The procedures implemented to identify the minimum grade and cut-off GT (Grade in U₃O₈ x thickness) product for mineral resource estimation are described below under the heading “US Mining Division – Mineral Properties – Henry Mountains Complex – Cut-Off Grade and Mining Considerations”.

Tony M Property

The same suite of logging surveys and procedures as employed at the Bullfrog property were conducted for the Tony M property. Assays of samples from core drilling were collected and submitted for analysis. Confirmation assays of chemical U₃O₈% were completed on drill core samples for comparison and calibration with eU₃O₈% values from gamma logging.

G-29

Status of Chemical Equilibrium of Uranium

Bullfrog Property

Exxon conducted analyses of samples from core drilling in the Southwest and Copper Bench deposits and found that the radioactive disequilibrium of potentially economic grade intercepts in cores, measured as the ratio of chemical U₃O₈ % to log radiometric equivalent (eU₃O₈%), varied from 0.80 to 1.35 and averaged 1.06, close to the equilibrium value of 1.0. Other investigations had identified no significant disequilibrium problem.

Tony M Property

Plateau conducted an extensive investigation of the state of chemical disequilibrium of uranium in the Tony M deposit. In 1989, Nuclear Assurance Corporation (“NAC”) reported that an analysis of results from 1,763 samples, including 1,137 composite samples collected from buggies coming from Tony M, was completed in 1983. Based on that analysis, it was concluded: (i) the state of disequilibrium varies from location to location within the deposit; (ii) with the exception of one small area in the southern part of the deposit, the equilibrium factor is positive; (iii) low grade material with less than 0.06% U₃O₈ is depleted in uranium; and (iv) higher grade material containing more than 0.06% U₃O₈ is enriched in uranium.

Scott Wilson RPA is of the opinion that based on the information available, the original gamma log data and subsequent conversion to eU₃O₈% values are reliable but slightly conservative estimates of the uranium U₃O₈% grade. Furthermore, there is no evidence that radiometric disequilibrium would be expected to negatively affect the uranium resource estimates of the Henry Mountains Complex.

Data Verification

Based on its review of the grade and thickness of uranium mineralization determined in the original gamma logs and a comparison with the computer generated GT composites, Scott Wilson RPA is of the opinion that the original gamma log data and subsequent conversion to eU₃O₈ values are reliable. Furthermore, Scott Wilson RPA reviewed the chemical analyses of core from diamond drill holes from the Bullfrog property and is of the opinion that the gamma logging results for the Bullfrog property provide a reliable, but conservative, estimate of the uranium content. The review suggests that the Mineral Resource estimate may underestimate the uranium content of the Bullfrog property by up to about 5%.

Security of Samples

Procedures followed during exploration were well documented and at the time followed best practices and standards of companies participating in uranium exploration and development. Onsite collection of the downhole gamma data and onsite data conversion limit the possibility of sample contamination or tampering.

Mineral Resource Estimation

In the Henry Mountains Technical Report, Scott Wilson RPA audited the 1993 EFN Mineral Resource estimate of the Copper Bench and Indian Bench deposits on the Bullfrog property and the Southwest deposit on the Tony M property, accepted them as a current Mineral Resource estimate and classified them as Indicated Mineral Resources and Inferred Mineral Resources.

The basis for this mineral resource estimation is the gamma logs from 1,801 rotary drill holes located on the Southwest, Copper Bench and Indian Bench deposits. This represents about 80% of the 2,232 total holes drilled on these deposits. A total of 81 core holes were drilled to recover samples for chemical and geologic analysis and to establish stratigraphic relationships. All of the drilling and analyses were conducted prior to Denison’s tenure. See “US Mining Division – Mineral Properties – Henry Mountains Complex – Drilling” above for further detail.

The grades of the mineralized zones were calculated on a polygonal block-by-block basis. The pounds of eU₃O₈ for each polygon were then tabulated along with the area and calculated volume for each block. The total number of tons and pounds of eU₃O₈ contained in the blocks were summed to provide a total inventory for each of the three deposits. Average grades for each deposit were estimated from the grades of the drill hole intersections used in the mineral resource estimate weighted by tonnage.

G-30

In the preparation of the Henry Mountains Tony M – Southwest Technical Report, Scott Wilson RPA audited the Mineral Resource estimates of the Tony M and Southwest deposits prepared by Denison using the contour method in 2008 and accepted them as a current Mineral Resource estimate, and has classified them as Indicated Mineral Resources and Inferred Mineral Resources. This new estimate provides an update of the Southwest deposit which was previously included in the Henry Mountains Technical Report.

The results of 1,671 drill holes were used to prepare the Mineral Resource estimates for the Tony M and the Southwest deposits. A total of 32 core holes were drilled to recover samples for chemical and geologic analysis and to establish a stratigraphic relationship. All of the drilling and analyses were conducted prior to Denison’s tenure. See “Drilling” above for further detail.

The following table lists the Mineral Resources by deposit for the entire Henry Mountains Complex.

Total Inferred		1.61	0.25	8.08

Notes:

(1) The mineral resource estimates comply with the requirements of NI 43-101 and the classifications comply with CIM definition standards.

(2) The Tony M and Southwest mineral resources were estimated at a cut-off grade of 0.10% eU₃O₈ over a minimum thickness of 2 feet and a minimum GT of 0.2 feet-%.

(3) The Indian Bench and Copper Bench mineral resources were estimated at a cut-off grade of 0.20% eU₃O₈, a minimum thickness of 4 feet and a minimum GT of 0.8 feet-% that does not include any intervals with less than a 0.5 foot intercept of 0.08% U₃O₈.

Cut-Off Grade and Mining Considerations

The selection of a 0.20% eU₃O₈ cut-off for the Copper Bench and Indian Bench was made by Scott Wilson RPA based on evaluations of current mining and processing costs made by both Denison and other operators in the region.

The 0.20% eU₃O ₈ cut-off maximizes the tonnage of higher grade mineralization while maintaining strong positive value. Based on the extensive review of the drilling, Scott Wilson RPA notes that lowering the cut-off criteria will increase total tonnage by increasing the number of drill hole intercepts meeting the cut-off, while also increasing the apparent continuity of mineralization between adjacent drill holes.

For the Tony M and Southwest deposits, Denison established minimum grade, thickness and GT parameters based on conventional Colorado Plateau mining practices and recent operating costs at Tony M.

As an initial step for the compositing of the drill hole assays, minimum grades of 0.10%, 0.08%, 0.05% and 0.03% eU₃O₈ were used over a minimum thickness of two feet, with a two foot minimum for exclusion of waste intervals. This resulted in minimum GT values of 0.20 feet-%, 0.16 feet-%, 0.10 feet-% and 0.06 feet-%, respectively. The two-foot thicknesses are based on the mining technique of split shooting, which is commonly used in the Uravan District. For inclusion of blocks in the mineral resource estimate, Denison used a cut-off grade of 0.10% eU₃O₈ .

G-31

Arizona Strip

Denison currently holds a 100% interest in eight breccia pipe uranium deposits in the Arizona Strip district of northwestern Arizona, being: Arizona 1, Canyon, Pinenut, EZ 1, EZ 2, WHAT, DB 1, and Kanab North. The EZ 1, EZ 2, WHAT, DB 1 and a fifth deposit, Moonshine Springs, were acquired from Pathfinder in 2007. Moonshine Springs is a sandstone hosted deposit near the surface which gradually becomes deeper toward the north.

On March 26, 2007, Denison filed, on the SEDAR website at www.sedar.com, an independent technical report entitled “Technical Report on the Arizona Strip Uranium Project” prepared by Scott Wilson RPA in accordance with the requirements of NI 43-101 with respect to Arizona 1, Canyon and Pinenut (the “Arizona Strip Report”).

An independent technical report titled “Technical Report on the EZ1 and EZ2 breccia pipes, Arizona Strip District, USA” prepared by Scott Wilson RPA in accordance with the requirements of NI 43-101 with respect to Denison’s EZ 1 and EZ 2 properties (“EZ Complex”) was filed on August 11, 2009 (the “EZ Complex Report”).

Mining operations began at Arizona 1 in late 2009. At Pinenut, mine development activities began in late 2010. See “US Mining Division – Operations – US Mines – Arizona Strip”. At Canyon, all surface facilities for shaft sinking are in place, and development is anticipated to begin in 2012. Kanab North, mined previously, is reported to have only minor quantities of mineralized material remaining in place and is not included in the Mineral Resource estimates in the Arizona Strip Report. An EIS is being prepared for the EZ Complex. The DB 1 and Moonshine Springs properties have no development on site or plans for permitting at this time.

Property Description and Location

Prior to 1995, EFN located and developed to various stages, numerous uranium mineralized breccia pipe structures in northwestern Arizona, between Utah and the Grand Canyon, an area termed the “Arizona Strip.” Most of Energy Fuels’ breccia pipes are between the town of Fredonia, on the Arizona Utah state line, and Grand Canyon National Park. These include the Pinenut, Arizona 1 and EZ Complex pipes. Canyon is located south of the park.

Arizona 1 is located in Mojave County, Arizona, about 45 miles southwest from Fredonia, Arizona by unsurfaced road. Energy Fuels’ property position will consist of ten unpatented mining claims covering approximately 207 acres.

Pinenut consists of 10 unpatented mining claims encompassing 207 acres. It is located 45 miles south of Fredonia in Mojave County, Arizona and is accessible via an unsurfaced road.

Canyon is in north central Arizona, 153 miles north of Phoenix and ten miles south of Grand Canyon Village in the Kaibab National Forest, Coconino County and is accessible by an unsurfaced road. The Canyon site consists of nine unpatented mining claims encompassing approximately 186 acres. There is a 3.5% yellowcake royalty on Canyon.

The EZ Complex is also located in Mohave County, Arizona, about 30 miles southwest of Fredonia, Arizona. The EZ Complex is comprised of 12 unpatented mining claims covering approximately 248 acres. There is a 1.0% yellowcake royalty on the EZ Complex properties.

Accessibility, Local Resources, Physiography and Infrastructure

Climate in northern Arizona is semi-arid, with cold winters and hot summers. January temperatures range from about 7° F to 57° F and July temperatures range from 52° F to 97° F. Annual precipitation, mostly in the form of rain but some snow, is about 12 inches. Vegetation on the plateaus is primarily open piñon juniper woodland and shrubs. Mining operations can be conducted on a year around basis.

The region north of the Grand Canyon is very sparsely populated. Due to the inaccessibility and low population, infrastructure is not well developed. The nearest commercial centres to the Fredonia area are the towns of St. George and Cedar City, Utah, both approximately 88 miles to the northwest by road. White Mesa is approximately 275 miles by road from Fredonia and about 325 miles by road from Canyon.

Arizona 1 was substantially developed in the 1990’s with the production shaft completed 1,250 feet of the proposed final 1,650 foot depth. Drill stations were cut near the current shaft bottom, and some 40,000 feet of drilling were completed from those stations. A headframe, hoist and compressor are in place. Denison completed rehabilitation work, and following receipt of all necessary permits in 2009, recommenced mine development.

Pinenut is a fully developed underground mine that produced about 0.5 million pounds U₃O₈ in 1989. A hoist, headframe and compressor are in place. Denison completed the construction of a larger stormwater pond and has begun rehabilitation work in anticipation of commencing production in 2012.

Only surface development has been completed at Canyon with a headframe, hoist and compressor in place. The shaft has been collared to a depth of 50 feet. The Denison Board approved development of Canyon in March, 2012.

There is no infrastructure in place at the EZ Complex.

History

Uranium exploration and mining of uranium deposits started in 1951 when a geologist employed by the US Geological Survey noted uranium ore on the dump of an old copper prospect on the South Rim of the Grand Canyon in northern Arizona. The prospect was inside Grand Canyon National Park, but on fee land that predated the park. A mining firm acquired the prospect and mined a significant high grade uranium deposit, the Orphan Mine. By the time mining ended in the early 1960s, 4.26 million pounds of U₃O₈ and some minor amounts of copper and silver had been produced.

After the discovery of the first deposit in the 1950s, an extensive search for other deposits was made by the government and industry, but only a few low grade prospects were found. Exploration started again in the early 1970s. In the mid 1970s, Western Nuclear Inc. acquired a prospect located about 25 miles north of the Grand Canyon and found high grade uranium mineralization offsetting an old shallow copper/uranium site. In the next few years, a second deposit was found approximately one mile away.

EFN acquired the property from Western Nuclear Inc. in December, 1980. Development started promptly, with a mine in production by the end of 1981.

The Kanab North deposit was discovered in 1981, but development did not begin until late 1984. Kanab North was fully developed in 1988 and operated until December, 1990, when it was placed on standby. Production totalled about 2.8 million pounds of U₃O₈ at an average grade of just over 0.50% U₃O₈. Some minor quantity of mineralized material remains.

EFN drilled a total of 253 drill holes at Arizona 1, including: 18 core holes from underground drill stations with a total footage of 6,122 feet; 17 rotary holes from surface with a total footage of 25,289 feet; and 218 long holes from underground drill stations with a total footage of 36,189 feet. Mine development at Arizona 1 began in 1990 but was suspended in 1992, with the shaft at a depth of 1,254 feet.

Canyon is located on mining claims that EFN acquired in 1982. Drilling completed by EFN in 1983 identified a significant deposit. EFN drilled 36 holes from May, 1983, through April, 1985, to delineate the uranium mineralization and to determine placement of the mine shaft and water supply well. Additional drilling of six holes was completed in 1994. Development of the site was discontinued as a result of low uranium prices.

Pinenut was developed in 1989, but saw only minor production, approximately 0.5 million pounds U₃O₈ at an average grade of 1.02% U₃O₈, before being placed on standby.

The EZ Complex was drilled in the 1980’s by Pathfinder. Pathfinder drilled 81 holes, totalling 139,118 feet. Pathfinder entered into a joint venture with EFN and prepared mineral resource estimates in 1988. When Denison acquired EFN’s mining properties in 1997, the EFN/Pathfinder joint venture was terminated and control of EZ 1 and EZ 2 had reverted back to Pathfinder. Denison acquired EZ 1 and EZ 2 from Pathfinder in 2007.

G-33

EFN identified and investigated more than 4,000 circular features in northern Arizona. One hundred and ten of the most prospective features were explored by deep drilling, and approximately 50% of those drilled were shown to contain uranium mineralization. Ultimately, nine pipes were deemed worthy of development. Total mine production from the EFN breccia pipes from 1980 through 1991 was approximately 19.1 million pounds U₃O₈ at an average grade of just over 0.60% U₃O₈.

Most of the assets of EFN were acquired by Denison in 1997. Since that time, Denison has maintained its ownership of Kanab North, Pinenut, Arizona 1, and Canyon. All other EFN prospects were dropped. In addition to the EFN breccia pipe deposits, Denison acquired four additional breccia pipe deposits (EZ 1, EZ 2, WHAT and DB 1) and one sandstone type deposit (Moonshine Springs) from Pathfinder.

Geological Setting

Parts of two distinct physiographic provinces are found within Arizona: the Basin and Range Province in the southern and western edge of the state, and the Colorado Plateau Province in most of northern and central Arizona. The Arizona Strip lies within the Colorado Plateau Province.

Surface exposures within the Arizona Strip reveal sedimentary and volcanic rocks ranging in age from Upper Paleozoic to Quaternary. The area is largely underlain by Mississippian through Triassic sedimentary rock; however, exposed within the Grand Canyon are older rocks reaching Precambrian in age.

Arizona 1, in common with all other breccia pipes within the Arizona Strip, was believed by EFN to have had its origin as a solution collapse of the Redwall Limestone. This collapse worked its way upward through the overlying formations where the throat diameter is between 200 feet to 300 feet. Vertical displacement in the throat averages 175 feet. Uranium mineralization is distributed irregularly over a depth interval of approximately 650 feet mainly at the level of the Hermit Shale formation to a maximum depth of 1,400 feet from surface.

At Canyon, the surface expression of the pipe is a broad shallow depression in the Permian Kaibab Formation. The pipe is essentially vertical with an average diameter of less than 200 feet, but it is considerably narrower through the Coconino and Hermit horizons (80 feet). The cross sectional area is probably between 20,000 and 25,000 square feet. The pipe extends for at least 2,300 feet from the Toroweap limestone to the upper Redwall horizons. The ultimate depth of the pipe is unknown.

Mineralization extends vertically both inside and outside Canyon over 1,700 vertical feet, but ore grade mineralization has been found mainly in the Coconino, Hermit, and Esplanade horizons and at the margins of the pipe in fracture zones. Sulphide zones are found scattered throughout the pipe but are especially concentrated (sulphide cap) near the Toroweap Coconino contact, where the cap averages 20 feet thick and consists of pyrite and bravoite, an iron-nickel sulphide. The mineral assemblage consists of uranium-pyrite-hematite with massive copper sulphide mineralization common in and near the ore zone. The strongest mineralization appears to occur in the lower Hermit-upper Esplanade horizons in an annular fracture zone.

Uranium mineralization in EZ 1 and EZ 2 is located primarily in the Coconino and Hermit horizons.

Deposit Types

Paleozoic sedimentary rocks of northern Arizona are host to thousands of breccia pipes. The pipes are known to extend from the Mississippian Redwall Limestone to the Triassic Chinle Formation, which makes for approximately 4,000 feet of section. However, because of erosion and other factors, no single pipe has been observed cutting through the entire section. No pipe is known to occur above the Triassic Chinle Formation or below the Mississippian Redwall Limestone.

Breccia pipes within the Arizona Strip are vertical or near vertical, circular to elliptical bodies of broken rock. Broken rock is comprised of slabs and rotated angular blocks and fragments of surrounding and stratigraphically higher formations. Hence, many geologists consider the pipes to have been formed by solution collapse of underlying calcareous rocks, such as the Redwall Limestone. Surrounding the blocks and slabs making up the breccia is a matrix of fine material comprised of surrounding and overlying rock from various formations. The matrix has been cemented mostly by silicification and calcification.

Breccia pipes are comprised of three interrelated features: a basinal or structurally shallow depression at surface (designated by some as a collapse cone); a breccia pipe which underlies the structural depression; and annular fracture rings which occur outside of, but at the margin of the pipes. Annular fracture rings are commonly, but not always, mineralized. The structural depression may range in diameter up to 0.5 miles or more, whereas breccia pipe diameters range up to about 600 feet; the normal range is 200 feet to 300 feet.

G-34

Mineralized breccia pipes found to date appear to occur in clusters or trends. Spacing between pipes ranges from some hundreds of feet within a cluster to several miles within a trend. Pipe location may have been controlled by deep seated faults, but karstification of the Redwall Limestone in Mississippian and Permian times is considered to have initiated formation of the numerous and widespread breccia pipes in the region.

Exploration

Denison has not carried out any exploration on Arizona 1, Pinenut, Canyon or the EZ Complex since it acquired these properties.

Mineralization

In the breccia pipe deposits, uranium occurs largely as blebs, streaks, small veins, and fine disseminations of uraninite/pitchblende. Mineralization is mainly confined to matrix material, but may extend into clasts and larger breccia fragments, particularly where these fragments are of Coconino sandstone. In addition to uranium, an extensive suite of elements is reported to be anomalously concentrated in mineralized rock within breccia pipes throughout northern Arizona. Within many pipes, there is a definite mineralogical zoning in and around the uranium mineral body.

Breccia pipes are surrounded by bleached zones, particularly notable in the Hermit formation where unaltered red sediments contrast sharply with grey-green bleached material. Both age dating and disequilibrium determinations indicate that remobilization of uranium has occurred. Uranium concentrations in the upper levels of a pipe tend to be in equilibrium, with disequilibrium in the mineral bodies increasing in favour of the chemical assays in deeper levels of a pipe.

Uranium mineralization within Arizona 1 extends significantly in the vertical dimension. Continuous drill hole intersections of several tens of feet with grades exceeding 1.00% U₃O₈ or more are not uncommon. The maximum continuous surface drill hole intersection was 92.5 feet at an average grade of 1.55% U₃O₈. On average, the 12 drill holes from surface which had intersected uranium mineralization recorded 75 feet of 0.62% U₃O₈.

Uranium mineralization at Canyon is concentrated in three stratigraphic levels: Coconino, Hermit/Esplanade, and a lower zone. Mineralization extends vertically from a depth of 600 feet to over 2,100 feet. Intercepts range widely up to several tens of feet with grades in excess of 1.00% U₃O₈ . Twenty-two drill holes from surface encountered uranium mineralization averaging 100 feet of 0.45% U₃O₈ .

Uranium mineralization at EZ 1 occurs at two distinct vertical intervals. The upper zone is contained within a 400-foot interval, 1,170 to 1,560 feet below surface and at its widest point has a diameter of approximately 183 feet. The lower zone is at a depth of 1,812 to 2,143 feet and at its widest point has a diameter of 45 feet. At EZ 2, the mineralization occurs in three distinct zones: an upper, middle and lower zone. The larger upper zone is mushroom shaped and is approximately 300 feet wide at its widest point and occurs from 952 feet to 1,153 feet below surface. The middle zone is made up of two central deposits surrounded by multiple ring deposits. An array of deposits in the middle zone occurs between depths of 1,194 to 1,356 feet. The lower zone also is a mushroom shaped deposit from 1,417 to 1,512 feet.

G-35

Drilling

Exploration drilling of breccia pipes is a difficult process. Substantial depths, approximately 2,000 feet, small targets, approximately 200 feet in diameter, and non-homogeneous rock formations combine to limit the accuracy of the drilling process. The presence of cavernous and brecciated sediments near the present land surface can result in loss of circulation of drilling fluid and as a result, much drilling is conducted “blind.” Periodic “spot cores” are taken to determine whether or not holes are within the target structure or have drifted away from the pipe. Indeed, most pipes cannot be completely drilled out from the surface due to deviation from desired targets. All drill holes are surveyed for deviation and logged with gamma logging equipment.

If surface drilling provides sufficient encouragement that a mine can be developed, on that basis a vertical shaft is sunk or drilled to its ultimate depth and underground drill stations are established at various levels to provide platforms for further exploration and delineation drilling. Drilling from underground stations typically utilizes large bore percussion drills. The resulting drill holes, out to as much as approximately 200 feet or so, are then gamma logged and surveyed as a supplement to surface drilling.

Sampling Method and Approach

All of the historical drill holes on the Arizona Strip properties were gamma logged and surveyed for deviation. This data provided the basic building blocks from which quantities of mineralized material were estimated. Core holes were drilled to supplement this data, to provide information for determination of disequilibrium, and to accommodate material for metallurgical testing. The process was consistent with industry standards when completed and the work carried out by EFN was judged by Scott Wilson RPA to have been of superior quality.

All of the basic data for calculation of quantities and grades of mineralized material for Arizona 1, Pinenut, Canyon, and EZ1 and EZ2 was derived directly by gamma log interpretation. Numerous checks were completed on this data by means of chemical assays, closed-can assays, and various beta gamma analyses.

G-36

Sample Preparation, Analyses and Protocols

Industry standards for uranium exploration in the western United States are based almost completely on the gamma logging process with a number of checks, including: (i) frequent calibration of logging tools, (ii) core drilling and chemical analysis of core as a check on gamma log values and the potential for disequilibrium; (iii) possible closed-can analysis as an adjunct to chemical assays; and (iv) possible gamma logging by different tools and/or companies.

EFN used the GAMLOG computer program to interpret gamma-ray logs (“GAMLOG”). GAMLOG was developed by the US Atomic Energy Commission. The essence of the method is a trial and error iterative process by which U₃O₈ grades are determined for a series of  ¹/2-foot or 1-foot layers which can be considered to comprise the zone under analysis. The objective of the iterative process is to find a grade for each separate layer such that an imaginary set of separate gamma-ray anomalies (one from each separate layer) could be composited to form an overall anomaly which would closely match the real anomaly under analysis.

Security of Samples

There are no specific provisions for security of data or samples other than those employed for confidentiality. The previous property owners are deemed to have met or exceeded industry standards for the exploration process.

Data Verification

Data verification in uranium exploration in the western United States takes the form of a combination of logging tool calibration, chemical assays on core, and various checks by other logging units and outside laboratories. Most of this verification process is internal and company specific. Independent verification has not been part of the industry standard process. EFN operations in the Arizona Strip are judged by Scott Wilson RPA to have met or exceeded industry standards.

Mineral Resource and Mineral Reserve Estimates

Initial Mineral Resource estimates were prepared for Arizona 1, Canyon, Pinenut and the EZ Complex using historical drill hole data provided by Denison. Scott Wilson RPA interpreted a set of cross sections and plan views to construct 3-D grade-shell wireframe models at 0.2% eU₃O₈ . Variogram parameters were interpreted and eU₃O₈ grades were estimated in the block model using kriging. The grade-shell wireframes were used to constrain the grade interpolation. All blocks within the 0.2% eU₃O₈ grade-shell wireframes, regardless of grade, were included in the mineral resource estimate. There are no mineral reserves estimated at any of the five deposits at this time. Scott Wilson RPA estimated the inferred mineral resources as shown below.

Arizona Strip Inferred Mineral Resource Estimates⁽¹⁾

	Tons (,000)	Grade eU3O8(2)(3) (%)	Contained eU3O8 (,000 pounds)
Arizona 1	70.3	0.68	956
Canyon	70.5	1.08	1,523
Pinenut	99.2	0.44	873
EZ 1	110.5	0.51	1,127
EZ 2	113.7	0.43	978

Notes:

(1) The Mineral Resource estimates comply with the requirements of NI 43-101 and the classifications comply with CIM definition standards.

(2) Interval grades were converted from the gamma log data and are therefore equivalent U₃O₈ (eU₃O₈).

(3) High eU₃O₈ grades were cut to 6% at Arizona 1, 10% at Canyon, and 8% at Pinenut, EZ 1 and EZ 2.

Cut-off Grade

In its feasibility studies of the various Arizona Strip breccia pipes compiled during the 1980s and 1990s, EFN typically used a cut-off grade of 0.15% U₃O₈. A reasonable cut-off grade for long term sustainable market conditions would be approximately 0.20% U₃O₈. This cut-off grade was applied by Scott Wilson RPA to all the breccia pipes deposits.

G-37

Mineral Resource and Reserve Update

Since the Mineral Resource estimates were prepared by Scott Wilson RPA, the Mineral Resources were updated for Pinenut and Canyon by Denison. Furthermore, at Arizona 1, mining operations have been underway since late 2009. As a result of the updates and the mining operations, the following illustrates the current mineral resource estimates for the Arizona Strip properties.

Arizona Strip Inferred Mineral Resource Estimate Update (in thousands of pounds U₃O₈)

Note:

(1) Additions or deletions to Mineral Resource estimates include reassessment of geological data.

Historical Estimates

On several of the mineral properties, estimates of Mineral Reserves or Mineral Resources have not been prepared in accordance with NI 43-101; however, historical mineral resource estimates exist for the projects, as discussed below. Denison did not treat the following historical estimates as current Mineral Resources or Mineral Reserves. Denison did not undertake the work necessary to have the historical estimates verified by a Qualified Person. These historical estimates have not been categorized. The properties will require confirmatory drilling and data collection to convert historical estimates into NI 43-101 compliant resources.

In 2007, Denison acquired five uranium deposits located in the Arizona Strip district in northeastern Arizona from Pathfinder, including four breccia pipe type deposits (EZ 1, EZ 2, WHAT and DB 1) and a sandstone hosted deposit occurring at surface and gradually becoming deeper towards the north (Moonshine Springs).

Shown below are the historical mineral resource estimates for DB 1 and Moonshine Springs as presented by Pathfinder to Denison and estimated in 1996 (the “Pathfinder Historical Estimates”). No cut-off grades have been reported for DB 1, while a 0.05% U₃O₈ cut-off has been used for Moonshine Springs.

Pathfinder Historical Estimates⁽¹⁾⁽²⁾

Deposit	Tons (,000)		Grade % U3O8			Pounds of U3O8 (,000)
DB 1		103.6		0.44	%		911
Moonshine Springs		761.7		0.16	%		2,483

Notes:

(1) The historical estimates do not comply with the requirements of NI 43-101. CIM definitions are not used.

(2) The historical estimates cannot be verified and the estimates are not necessarily indicative of the mineralization on the property.

The Pathfinder Historical Estimates are based on data, reports and documentation obtained from and prepared by previous operators, including AREVA, which were not verified by Denison. The properties will require considerable further evaluation to upgrade this historical estimate as a current Mineral Resource estimate, which, provided the Arrangement is completed, Energy Fuels’ management and consultants intend to carry out in due course.

In the Colorado Plateau District, Denison mined uranium and vanadium bearing ore from Sunday and Rim from November, 1997 to mid-1999, then Topaz, Sunday/St. Jude and West Sunday beginning in 2008 to 2009, and is currently mining ores from Pandora and Beaver. In 2011, 172,600 tons of ore from the Colorado Plateau were milled at White Mesa.

In June, 2011, Denison acquired uranium and vanadium properties in southeastern Utah pursuant to the White Canyon Acquisition. The properties are in two widely separated geographic areas: a northern area in the region of Thompson, Utah, which is in the Colorado Plateau District; and, a southern area called the White Canyon District. Historical estimates have been reported for the following White Canyon properties (the “White Canyon Historical Estimates”).

(3) The Daneros and Lark Royal historical estimate has been adjusted to reflect actual mine production by White Canyon and Denison.

The White Canyon Historical Estimates for Daneros and Lark Royal are based on Denison’s analysis of work conducted by a previous operator, UP&L. In 2010 and 2011, White Canyon prepared the following estimates:

“Technical Report on Utah Energy Corporation’s Geitus—Deer Flat Project, San Juan County, Utah, February 15, 2011” prepared by Integrated Production Resources of Centennial, Colorado.

“Technical Report on Utah Energy Corporation’s Blue Jay Project, San Juan County, Utah, February 22, 2011” prepared by Integrated Production Resources of Centennial, Colorado.

“Technical Report on Utah Energy Corporation’s Geitus—Marcy Look Project ,San Juan County, Utah, December 28,2010” prepared by Integrated Production Resources of Centennial, Colorado.

These reports were prepared in accordance with the JORC Code prior to Denison’s involvement with White Canyon. These reports were based on analysis by Integrated Production Resources utilizing data, reports, and documentation obtained from and prepared by previous operators, which have not been verified by Denison. The properties will require considerable further evaluation to upgrade these historical estimates to Mineral Resource estimates pursuant to NI 43-101, which work Energy Fuels’ management and consultants intend to carry out in due course provided the Arrangement is completed.

G-39

To Energy Fuels’ knowledge, no Mineral Resources estimates have been prepared for the properties in the Colorado Plateau District.

Mineral Exploration

DMHC indirectly holds exploration properties in the Colorado Plateau, White Canyon, and Arizona Strip Districts. Exploration drilling has been conducted in the Colorado Plateau District in recent years, with the majority of the work directed to brown fields drilling to extend active mining areas.

In the Colorado Plateau District, exploration projects include extensions of the geologic trends in the vicinity of the Sunday Mines Complex. Properties are also held which cover areas that are favourable for exploration for new discoveries for salt wash uranium/vanadium deposits similar to the deposits in the Sunday Mines area.

The majority of 2010 drilling in the US was directed to the Beaver area. A total of 62 holes totalling 13,755 metres (45,129 feet) were completed along known trends and in areas between mineralized pods where historical drilling is limited. A new mineralized channel was delineated parallel to active mining in the west Beaver area; the new zone is approximately 300 metres long. Eleven holes totalling 1,963 metres (6,440 feet) were drilled in advance of active mine areas at Pandora. Results of this drilling were negative, and future drilling will focus on stepping out to new target areas further removed from current mining areas. Energy Fuels anticipates implementing Denison’s plans in the Beaver area.

Drilling at Beaver and Redd Block in 2011 totalled 15,510 metres (50,889 feet) in 68 holes, which includes nine monitoring wells installed at Redd Block for baseline data collection and future groundwater monitoring. Two new areas of mineralization were discovered which can be accessed from existing mine workings. These Mineral Resources more than replaced production from Beaver in 2011.

For 2012, Denison planned three drill programs in the vicinity of the Pandora, Beaver and Redd Block areas. In total, the program was anticipated to drill 20,125 metres in approximately 80 drill holes. Energy Fuels anticipates completing the drill program as planned.

In the Arizona Strip District, Denison holds 100% interest in several claims blocks, all of which host confirmed breccia pipe features. Mineralization has been encountered in past drilling on a number of these features, and additional deep drilling is required to confirm Mineral Resources. Denison had plans to drill six deep exploration holes, to confirm a known discovery and to support Mineral Resource estimation, on DB 1. DB 1, as well as nearly all of the known breccia pipes exploration targets on lands that will be held by Energy Fuels in the Arizona Strip District, is within the area withdrawn by the US Department of Interior. Drilling at DB 1 in 2012 is contingent upon BLM accepting Denison’s notice of intent to explore on withdrawal lands.

The White Canyon District includes claims and Utah State Leases covering historical mineral deposits in the Elk Ridge and Deer Flats areas. Exploration notices for surface drilling were obtained by UEC for the Geitus, Blue Jay, and Marcy Look areas. Denison is evaluating historic information on these areas to assess plans for exploration drilling.

Exploration notices have also been approved for brown fields drilling around Daneros. These Exploration notices cover the Daneros, Lark and Royal areas. Energy Fuels will review plans for additional surface drilling in the Daneros area.

Quality Assurance and Quality Control Procedures and Protocols

The following section details the Quality Assurance and Quality Control (“QA/QC”) procedures and protocols for all exploration programs operated by DMHC.

All uranium exploration technical information is obtained, verified and compiled under a formal QA/QC assurance and quality control program in the southwestern United States. The following details the protocols used by all Denison staff and consultants.

G-40

Processes for Determining Uranium Content by Gamma Logging

Exploration for uranium deposits in the southwest United States typically involves identification and testing of permeable sandstones within reduced sedimentary sequences. The primary method of collecting information is through extensive drilling and the use of down hole geophysical probes. The down hole geophysical probes measure natural gamma radiation, from which an indirect estimate of uranium content can be made.

The radiometric (gamma) probe measures gamma radiation which is emitted during the natural radioactive decay of uranium. The gamma radiation is detected by a sodium iodide crystal, which when struck by a gamma ray emits a pulse of light. This pulse of light is amplified by a photomultiplier tube, which outputs a current pulse. The gamma probe is lowered to the bottom of a drill hole and data is recorded as the tool is withdrawn up the hole. The current pulse is carried up a conductive cable and processed by a logging system computer which stores the raw gamma cps data.

If the gamma radiation emitted by the daughter products of uranium is in balance with the actual uranium content of the measured interval, then uranium grade can be calculated solely from the gamma intensity measurement. Down hole cps data is subjected to a complex set of mathematical equations, taking into account the specific parameters of the probe used, speed of logging, size of bore hole, drilling fluids and presence or absence of and type of drill hole casing. The result is an indirect measurement of uranium content within the sphere of measurement of the gamma detector.

The basis of the indirect uranium grade calculation (referred to as “eU₃O₈” or “equivalent U₃O₈”) is the sensitivity of the sodium iodide crystal used in each individual probe. Each probe’s sensitivity is measured against a known set of standard “test pits,” with various known grades of uranium mineralization, located at the DOE’s Grand Junction, Colorado office. The ratio of cps to known uranium grade is referred to as the probe “K-Factor”, and this value is determined for every gamma probe when it is first manufactured and is also periodically checked throughout the operating life of each probe. Application of the K-Factor, along with other probe correction factors, allows for immediate grade estimation in the field as each drill hole is logged.

Core Sampling, Processing, and Assaying

Core samples are collected for a number of purposes: verification of lithology as determined from geophysical logging and examination of drill cuttings; determination of uranium content as a general check of gamma probing to determine if gamma measurement and chemical uranium content are close to balance (“radiometric disequilibrium”); whole rock analysis; and specific geochemistry for uranium species and other minerals of interest. Typically core is only taken over select intervals of interest as identified from logging of drill holes. This reduces the amount of core through barren zones or horizons of no interest and greatly reduces overall exploration costs.

Core diameter is typically 2 ¹/2 – 3 ¹/4 inches. For zones selected for laboratory analyses, one half of the core will normally be used. The minimum length of core submitted is usually one foot and the maximum length per sample is two feet. Sample intervals are selected by geologists in the field based on lithology, oxidation/reduction, and uranium grade (from gamma logging and from hand-held gamma counters).

Core samples are prepared at White Mesa. Samples are crushed and then ground to -200 mesh. The sample pulps are split to 250 to 300 grams for laboratory work.

Quality Assurance and Quality Control Measures

Drill hole logging is conducted by Denison in-house personnel. The logging capabilities are designed specifically to meet Denison’s logging requirements in the southwest United States. The tools, and a complete set of spares, were manufactured by Mount Sopris Instrument Company in Golden, Colorado. Denison has retained the services of a senior geophysical consultant to oversee training, implementation, and quality control protocols for the southwest United States’ operations. All tools are checked and calibrated before being used, and a variety of system checks and standards are also established for routine checking and calibration of tools.

Drill hole logging data is stored on digital media in the logging truck at the exploration sites. The digital data is periodically brought in from the field locations to the Egnar, Colorado field office. The raw and converted logging data are copied and then sent via e-mail to Denison’s Denver office, where all data is checked and reviewed.

G-41

Samples of core are chosen on the basis of radiometric data collected during core logging. This radiometric data is obtained by using a hand held scintillometer. The general concept behind the scintillometer is similar to the gamma probe except the radiometric pulses are displayed on a scale and the respective count rates are recorded manually by the geologist logging the core. The hand-held scintillometer provides quantitative data only and cannot be used to calculate uranium grades. However, it does allow the geologist to identify uranium mineralization in the core and to select intervals for geochemical sampling.

Additional samples are collected above and below the horizons of interest in order to “close-off” sample intervals. Sample widths are selected according to radiometric values and lithologic breaks or changes. All reasonable efforts are made to ensure that splitting of the core is representative and that no significant sampling biases occur. Once the sample intervals are identified, an exclusive sample number is assigned each interval and recorded by the on-site geologist.

After the geological logging of the core and sample selection, all of the selected sample intervals of drill core are split longitudinally at the drill site. One half of the core is placed in a new sample bag along with a sample tag corresponding to the sample number. The other half of the core is re-assembled in the core box and stored for future reference. Samples are stored at the Egnar, Colorado office under the supervision of the project geologists and delivered to either White Mesa or Activation Laboratories Ltd. for preparation. As standard procedure, field duplicates are included in assay suites sent to the laboratories, and reference samples are used to verify laboratory controls and analytical repeatability.

Environmental and Safety Matters

Denison has adopted an Environmental, Health and Safety Policy (the “EHS Policy”) that affirms Denison’s commitment to environmentally responsible management and compliance with occupational health and safety laws. Under the EHS Policy, Denison has committed to run its operations in compliance with applicable legislation, in a manner that minimizes the impact on our ecosystem. The EHS Policy mandates the use of regular monitoring programs to identify risks to the environment, to the public and to Denison’s employees and to ensure compliance with regulatory requirements. The EHS Policy also sets out Denison’s requirement to train its employees regarding environmental and health and safety compliance and best practices and to provide adequate resources in this regard. Finally, the EHS Policy requires regular reporting to the Board regarding Denison’s compliance and the results of Denison’s monitoring. Energy Fuels plans to review the EHS Policy adopted by Denison and adopt it as written or with minor modifications.

White Mesa

White Mesa processed conventional ore through June, 2011, at which time processing ceased for maintenance work. Conventional ore processing resumed in November, 2011. The alternate feed circuit was operating throughout 2011. Mill operations registered one lost time accident in 2011, ending White Mesa’s record of 1.6 million man-hours without a lost time accident.

Denison has detected some chloroform contamination at the mill site that appears to have resulted from the operation of a temporary laboratory facility that was located at the site prior to and during the construction of the mill facility, and from septic drain fields that were used for laboratory and sanitary wastes prior to construction of the mill’s tailings cells. In April, 2003, Denison commenced an interim remedial program of pumping the chloroform contaminated water from the groundwater to the mill’s tailings cells. This will enable Denison to begin clean up of the contaminated areas and to take a further step towards resolution of this outstanding issue. Pumping from the wells continued in 2011. Denison is continuing to work with Utah to develop a long-term corrective action plan. A draft corrective action plan was submitted and is currently being reviewed by Utah. While the investigations to date indicate that this chloroform contamination appears to be contained in a manageable area, the scope and costs of final remediation have not yet been determined and could be significant.

In 2008, elevated concentrations of nitrate and chloride were observed in some monitoring wells at the mill site, a number of which are upgradient of the mill’s tailings cells. Pursuant to a stipulated consent agreement with UDEQ, Denison retained INTERA, Inc. (“INTERA”), an independent professional engineering firm, to investigate these elevated concentrations and to prepare a contamination investigation report for submittal to UDEQ. The investigation was completed in 2009 and the contamination investigation report was submitted to UDEQ in January, 2010 (the “INTERA Report”). INTERA concluded in the INTERA Report that: (1) the nitrate and chloride are co-extensive and appear to originally come from the same source; and (2) the source is upgradient of the mill property and is not the result of mill activities. UDEQ reviewed the INTERA Report and concluded that further investigations were required before UDEQ can determine the source of the contamination or assign the responsibility for clean up. Such investigations were performed in 2010 and 2011,

G-42

but were considered to be inconclusive by UDEQ. As a result, after over two years of investigation, it has been determined that there are site conditions that make it difficult to ascertain the source(s) of contamination at the site, and that it has therefore not been possible to date to determine the source(s), causes(s), attribution, magnitudes of contribution, and proportion(s) of the local nitrate and chloride in groundwater. For those reasons, UDEQ could not eliminate mill activities as a potential cause, either in full or in part, of the contamination. Denison and UDEQ have agreed that resources will be better spent in developing a corrective action plan, rather than continuing with further investigations as to the source(s) and attribution of the groundwater contamination. Pursuant to a revised stipulated consent agreement, Denison submitted to UDEQ in November, 2011 a draft corrective action plan for remediation of the contamination, which involves a program of pumping the nitrate contaminated groundwater to White Mesa’s tailings cells, similar to its chloroform remedial program. UDEQ is currently reviewing the proposed corrective action plan. Although the contamination appears to be contained in a manageable area, the scope and costs of final remediation have not yet been determined and could be significant.

Reclamation

White Mesa is subject to decommissioning liabilities. Denison, as part of the Utah Radioactive Licence, is required to annually review its estimate for the decommissioning of the White Mesa site and submit it to UDEQ for approval. The estimate of closure costs for the mill is US$19.4 million, and financial assurances are in place for the total amount.

US Mines

During 2011, Denison had four active mining operations, two in Utah and two in Arizona. There were five mines which were on care and maintenance.

In 2011, Arizona 1 received the 2010 US Department of Labor’s MSHA Sentinels of Safety Award in the small underground metal mine category. In 2010, Arizona 1 personnel worked a total of 56,417 injury-free hours. Daneros was recognized as a runner up with a total of 23,674 injury-free hours. The Sentinels of Safety Award acknowledges the men and women at those mines in the United States that have worked the most employee-hours without experiencing a lost-time injury.

There were two lost time accidents at the mining operations in 2011.

During 2011 and 2012, White Mesa reported consecutive exceedances of GWCLs under White Mesa’s GWDP for several constituents in several wells, and there is a decreasing trend in pH in a number of wells across the White Mesa site that have caused the pH in a number of compliance monitoring wells to have dropped below their GWCLs. These exceedances and pH trends include wells that are upgradient of the White Mesa facilities, far down-gradient of the White Mesa site and at the White Mesa site itself. These consecutive exceedances of GWCLs have resulted in violations of White Mesa’s GWDP, and Denison has submitted a plan and schedule to UDEQ to evaluate and further characterize the exceedances and trends. However, given the fact that trends in a number of constituents at the site have previously been determined to have been the result of natural causes, and that the exceedances and trends that have been recently identified and are the subject of current violations are widespread and include wells that are upgradient and far downgradient from the activities at White Mesa, Denison believes that these recently identified consecutive exceedances and trends are not the result of activities at White Mesa. If the exceedances and trends are determined to be the result of natural causes, then the applicable GWCLs may have to be re-evaluated. If the exceedances are determined to be caused by activities at White Mesa, then a corrective action plan for remediation would be required, the scope and costs of which would have to be determined and could be significant.

Reclamation

All of Energy Fuels’ mines in the US are subject to closure and reclamation liabilities. Denison estimated the reclamation costs for the various mining operations in Colorado, Utah and Arizona to be US$3.7 million. Financial bonds are in place for the total amount.

G-43

Government Regulation

Uranium milling in the US is primarily regulated by the NRC pursuant to the Atomic Energy Act of 1954, as amended. Its primary function is to ensure the protection of employees, the public and the environment from radioactive materials as well as regulating most aspects of the uranium recovery process. The NRC regulations pertaining to uranium recovery facilities are codified in Title 10 of the Code of Federal Regulations (“10 CFR”).

On August 16, 2004, Utah became an Agreement State for the regulation of uranium mills. This means that the primary regulator for White Mesa is now UDEQ rather than NRC. At that time, the mill’s NRC Source Material Licence was transferred to Utah and became the Utah Radioactive Licence. Utah incorporates, through its own regulations or by reference, all aspects of 10 CFR pertaining to uranium recovery facilities. White Mesa’s licence was due for renewal on March 31, 2007. Denison submitted its application for renewal of the licence on February 28, 2007. A draft renewal licence was published for comment by UDEQ in the fourth quarter of 2011 and will be republished for comment in the second quarter of 2012. Denison expects that the renewed license will be issued by UDEQ by the end of 2012. During the period that Utah is reviewing the licence renewal application, the mill can continue to operate under the Utah Radioactive Licence. The mill’s licence was initially issued in 1980 and was renewed in 1987 and 1997.

When Utah became an Agreement State it required that a GWDP be put in place. The GWDP is required for all similar facilities in Utah, and specifically tailors the implementation of Utah groundwater regulations to the mill site. Utah requires that every operating uranium mill have a GWDP, regardless of whether or not the facility discharges to groundwater. The GWDP for White Mesa was finalized and implemented in March, 2005. The GWDP required that the mill add over 40 additional monitoring parameters and fifteen additional monitoring wells at the site. The GWDP came up for renewal in 2010, and is currently in the renewal process. During the review period the mill can continue to operate under its existing GWDP.

White Mesa also maintains permit approvals for air emissions with the UDEQ, Division of Air Quality.

Uranium mining is subject to regulation by a number of agencies including: (1) local county and municipal government agencies; (2) the applicable State divisions responsible for mining and protecting the environment within Utah, Colorado and Arizona; (3) the BLM and the USFS on public lands under their jurisdiction; (4) the U.S. Mine Safety and Health Administration; and (5) other U.S. federal agencies where certain conditions exists, including the U.S. Fish and Wildlife Service and U.S. Army Corp of Engineers. A review of the major permits for each mine is included in the operations sections herein.

Land Tenure

Energy Fuels’ land holdings in the US will be held in fee simple by Energy Fuels by leases from the fee simple owners (private parties or the state or the federal government) or in patented or unpatented mining claims located on property owned by the US Federal Government. Annual fees must be paid to maintain unpatented mining claims, but work expenditures are not required. Holders of unpatented mining claims are generally granted surface access to conduct mineral exploration and mining activities; however, additional mine permits and plans are generally required prior to conducting exploration or mining activities on such claims.

On July 9, 2009, BLM issued a notice of proposed withdrawal (“2009 Notice”) under which it proposed that a total of approximately one million acres of public lands around the Grand Canyon National Park be withdrawn from location and entry under the Mining Law of 1872 (the “Mining Law”), subject to valid existing rights. In the 2009 Notice, BLM stated that the purpose of the withdrawal, if determined to be appropriate, would be to protect the Grand Canyon watershed from any adverse effects of locatable hardrock mineral exploration and mining. The 2009 Notice segregated the lands from location and entry under the mining laws for up to two years to allow time for various studies and analysis, including appropriate National Environmental Policy Act (“NEPA”) analysis. In order to allow more time for BLM to complete its NEPA analysis, the US Department of the Interior (“DOI”) published Public Land Order 7773 on June 21, 2011, which effected a six-month emergency withdrawal of the area. The emergency withdrawal prevented the lands from opening to location and entry under the Mining Law upon expiration of the two-year segregation while the DOI completed the decision–making process on the proposed withdrawal. The emergency withdrawal was effective from July 21, 2011, to January 20, 2012. During the two-year segregation and six month emergency withdrawal, the BLM, along with its cooperating agencies, completed various studies and analyses of resources in the withdrawal area, including an Environmental Impact Statement (“EIS”) under NEPA. These studies and analyses were undertaken to provide the basis for the final decision regarding whether or not to proceed with the proposed withdrawal or to select an alternative action. Based on this analysis, on January 9, 2012, the Department of the Interior announced its final decision to withdraw from location and entry under the Mining Law, subject to valid existing rights, the total of approximately one million acres of lands originally proposed in the 2009 Notice, for a 20-year period. Lawsuits challenging this decision have been filed by various industry groups and interested parties.

G-44

No new mining claims may be filed on the withdrawn lands and no new POs may be approved, other than POs on mining claims that were valid at the time of withdrawal and that remain valid at the time of plan approval. Whether or not a mining claim is valid must be determined by a mineral examination conducted by BLM or the USFS, as applicable. The mineral examination, which involves an economic evaluation of a project, must demonstrate the existence of a locatable mineral resource and that the mineral resource constitutes the discovery of a valuable mineral deposit.

All Arizona Strip properties, with the exception of Moonshine Springs are located within the withdrawn lands. BLM is currently undertaking a mineral examination on the EZ Complex, in conjunction with its review of the proposed PO for that project. Mineral examinations are not required for Arizona 1 and Pinenut, which have previously approved POs and are currently undergoing mining activities. Although Canyon also has an approved PO, and a mineral examination is not required, the USFS has elected to perform a mineral examination on that project, which is expected to be completed in the second quarter of 2012.

Denison believes that all of its material Arizona Strip projects are on valid mining claims that will each withstand a mineral examination. However, there can be no guarantee that a mineral examination will not result in one of more of Denison’s, and following the Arrangement, Energy Fuels’ mining claims being considered invalid, which could prevent a project from proceeding.

Legal and Regulatory Proceedings

Arizona 1 Licence Challenge

On November 16, 2009, as amended on February 1, 2010 and July 22, 2011, the Center for Biological Diversity, Grand Canyon Trust, Sierra Club, Kaibab Band of Paiute Indians and Havasupai Tribe (the “Plaintiffs”) filed a lawsuit in the US District Court for the District of Arizona (the “District Court”) against the US Secretary of the Interior and the BLM (together, the “Defendants”) seeking an order declaring that the Defendants violated environmental laws in relation to Arizona 1 by not requiring a new PO in connection with the start of mining activities. The Plaintiffs also claim that, if a new PO is not required, the Defendants failed to conduct a review of potential environmental impacts from the mine since the existing PO for the mine was approved by BLM in 1988. The Plaintiffs are seeking an order declaring that the Defendants have violated these environmental laws in relation to Arizona 1, and an injunction directing operations to cease and stopping the Defendants from authorizing or allowing any further mining or exploration operations at Arizona 1 until BLM complies with all applicable laws. On October 7, 2011, the District Court issued its final ruling in favour of the Defendants on all counts. On November 28, 2011, the Plaintiffs appealed the District Court’s ruling to the Ninth Circuit Court of Appeals (the “Court of Appeals”), and on December 8, 2011 filed a motion in the District Court for preliminary injunction, pending appeal. That motion was denied by the District Court on January 11, 2012. On January 26, 2012, the Plaintiffs filed an emergency motion for an injunction pending appeal in the Court of Appeals, which was denied by the Court of Appeals on February 24, 2012. The appeal of the District Court’s ruling is under way, and oral arguments and a decision from the Court of Appeal is expected in the 3^rd or 4^th quarter of 2012. If the Plaintiffs are successful on the appeal, Denison, and following the Arrangement Energy Fuels, may be required to stop mining activities at Arizona 1 pending resolution of this matter. Any required stoppage of mining could have a significant adverse impact on Denison, and following the Arrangement Energy Fuels.

La Sal Complex

On February 17, 2012, Uranium Watch and Living Rivers filed a Notice of Appeal and Petition for Stay with the Interior Board of Land Appeals (“IBLA”), relating to a January 18, 2012 response by BLM to a request for information made by Uranium Watch and Living Rivers. In that request, Uranium Watch and Living Rivers asked BLM to confirm, among other things, that the existing PO and related EA for a portion of La Sal are sufficient under BLM regulations and NEPA. In responding to that request, BLM stated that the PO is sufficient, that no new decisions have been made and that the related EA is sufficient until a new decision needs to be made. Uranium Watch and Living Rivers have alleged that this response by BLM constitutes an appealable decision by BLM and have requested a stay of operations at La Sal pending a decision by IBLA on the appeal. Denison was added as an intervener in this action on March 7, 2012. Both BLM and Denison have filed responses and motions to dismiss this action for lack of standing, on the basis that an appealable decision has not been made by BLM. A decision from IBLA is pending at this time.

G-45

Daneros

On July 28, 2011, the Southern Utah Wilderness Alliance filed a Notice of Appeal with the IBLA challenging BLM’s FONSI for Daneros’ EA, requesting that IBLA set aside the FONSI and remand the EA to the BLM with instructions to prepare an EIS or to revise the EA. Denison has been added as an intervenor in this action and believes this challenge is without merit and should be dismissed. Responses were filed by BLM and Denison in early December, 2011, and a decision from IBLA is pending at this time.

RISK FACTORS

The following is a summary of certain risk factors relating to the business of Energy Fuels and the US Mining Division. The following information is a summary only of certain risk factors and is qualified in its entirety by reference to, and must be read in conjunction with, the detailed information appearing elsewhere in this document. Readers should carefully consider the risks described under the heading “Description of the Business - Risk Factors” in the Energy Fuels AIF and the risk factors contained in Energy Fuels’ management’s discussion and analysis for the year ended September 30, 2011, which are incorporated by reference in and form an integral part of this Appendix G, as well as the risk factors set forth below.

Such risks may not be the only risks facing Energy Fuels. Additional risks not currently known may also negatively impact Energy Fuels’ business operations and results of operations. Readers are cautioned that the risk factors contained in and incorporated by reference in this Appendix G are not exhaustive.

Failure to Realize Anticipated Benefits of Strategic Acquisitions

Energy Fuels expects to continue to selectively seek strategic acquisitions. Energy Fuels’ ability to consummate and to integrate effectively any future acquisitions on terms that are favourable to it may be limited by the number of attractive acquisition targets, internal demands on Energy Fuels’ resources, and to the extent necessary, Energy Fuels’ ability to obtain financing on satisfactory terms, if at all. Future acquisitions may expose Energy Fuels to additional risks, including: difficulties in integrating administrative, financial reporting, operational and information systems and managing newly-acquired operations and improving their operating efficiency; difficulties in maintaining uniform standards, controls, procedures and policies through all of Energy Fuels’ operations; difficulties in retaining key employees of the acquired operations; and disruptions to Energy Fuels’ ongoing business.

In addition, future acquisitions could result in the incurrence of additional debt, costs, and contingent liabilities. Energy Fuels may also incur costs for and divert management attention to potential acquisitions that are never consummated. For acquisitions that are consummated, expected synergies may not materialize. Energy Fuels’ failure to effectively address any of these issues could have a material adverse effect on Energy Fuels’ business, financial condition, results of operations and cash flows.

While Energy Fuels’ acquisition process typically includes due diligence on the business or assets to be acquired, and the acquisition agreements typically include detailed representations and warranties respecting the business or assets being acquired, there can be no assurance that Energy Fuels will not become subject to certain undisclosed liabilities in proceeding with such transactions. These representations and warranties, if obtained, may not fully cover the liabilities because of their limited scope, amount or duration, the financial resources of the indemnitor or warrantor or for other reasons.

Energy Fuels has completed a number of acquisitions, including the Titan Arrangement and there may exist liabilities that Energy Fuels’ due diligence did not or was unable to discover prior to the consummation of these acquisitions. To the extent that prior owners of businesses failed to comply with or otherwise violated applicable laws, Energy Fuels, as a successor-owner, may be financially responsible for these violations. The discovery of any material liabilities could have a material adverse effect on Energy Fuels’ business, financial condition and future prospects.

G-46

Potential Exposure to Increased Environmental Costs and Liabilities

Energy Fuels and Denison are subject to a broad range of environmental laws and regulations in each jurisdiction in which they operate and are exposed to potentially significant environmental costs and liabilities. By acquiring the US Mining Division, Energy Fuels will be subject to additional liabilities for any environmental damage occurring on the properties comprising the US Mining Division under such environmental laws. These laws and regulations, as interpreted by relevant agencies and the courts, impose increasingly stringent environmental protection standards regarding, among other things, air emissions, wastewater storage, treatment and discharges, the use and handling of hazardous or toxic materials, waste disposal practices and the remediation of environmental contamination. The costs of complying with these laws and regulations including participation in assessments and remediation of sites, could be significant. In addition, these standards can create the risk of substantial environmental liabilities, including liabilities associated with divested assets and past practices and activities.

Market Price of EFI Shares

If the Arrangement is completed, a significant number of additional EFI Shares will be issued and will become available for trading in the public market. The increase in the number of EFI Shares may lead to sales of such shares or the perception that such sales may occur, either of which may adversely affect the market for, and the market price of, the EFI Shares.

Dilution

The issuance of EFI Shares upon the completion of the Arrangement will result in a substantial dilution of the equity interests of EFI Shareholders and any person who may become an EFI Shareholder as a result of or subsequent to the Arrangement.

Further, Energy Fuels may issue additional EFI Shares in the future, which may dilute a shareholder’s holdings in Energy Fuels or negatively affect the market price of the EFI Shares. Energy Fuels’ articles permit the issuance of an unlimited number of EFI Shares and an unlimited number of preferred shares, issuable in series, and shareholders will have no pre-emptive rights in connection with such further issuances. The directors of Energy Fuels have the discretion to determine the provisions attaching to any series of the preferred shares and the price and the terms of issue of further issuances of EFI Shares. Also, additional EFI Shares will be issued by Energy Fuels on the exercise of stock options under Energy Fuels’ stock option plan, upon the exercise of warrants, or pursuant to other share compensation arrangements.

Energy Fuels Financing Risk

If the Arrangement is completed, Energy Fuels will require additional funding in order to expand exploration, development and production projects on the US Mining Division and the Sheep Mountain Project and potential development of the Piñon Ridge Mill. If Energy Fuels’ proposed programs are successful, additional funds will required for the building of the Piñon Ridge Mill and the mining of uranium from the Sheep Mountain Project. The primary sources of future funds presently available to Energy Fuels are the sale of equity capital, or the offering by Energy Fuels of an interest in its properties to be earned by another party or parties carrying out exploration or development thereof. There can be no assurance that any such funds will be readily available to fund Energy Fuels’ future operations. Failure to obtain additional financing on a timely basis could cause Energy Fuels to reduce, delay or terminate its proposed operations, with may lead to the possible loss of such operations and corresponding adverse impact on the financial position of Energy Fuels.

PRIOR VALUATIONS

To the knowledge of Energy Fuels and the EFI Board and management, after reasonable enquiry, there have been no prior valuation opinions obtained within the 12 months preceding the date of this Information Circular by Denison or Energy Fuels required by securities legislation or a Canadian exchange or market to support the consideration paid by Energy Fuels for the US Mining Division.

Notes to the Pro Forma Condensed Consolidated Financial Statements

For the Six Months Ended March 31, 2012 and the Year Ended September 30, 2011

(Unaudited)

(Expressed in U.S. dollars)

1. Basis of presentation

These unaudited pro forma condensed consolidated financial statements have been prepared in connection with the proposed acquisition (the “Acquisition”) of Denison Mines Holding Corp. (“DMHC”) and White Canyon Uranium Limited (“White Canyon”) by Energy Fuels Inc. (“EFI” or the “Company”).

These unaudited pro forma condensed consolidated financial statements have been prepared for illustrative purposes only and give effect to the Acquisition pursuant to the assumptions described in Note 4 to these unaudited pro forma condensed consolidated financial statements. The unaudited pro forma condensed consolidated statement of financial position as at March 31, 2012 gives effect to the proposed Acquisition by EFI as if it had occurred as at March 31, 2012. The unaudited pro forma condensed consolidated statement of comprehensive loss for the twelve month period ended September 30, 2011 and for the six month period ended March 31, 2012 give effect to the proposed Acquisition as if it had occurred as at October 1, 2010. These unaudited pro forma condensed consolidated statements of comprehensive loss also give effect to the acquisition of Titan Uranium Inc. (“Titan”) by Energy Fuels as if the acquisition occurred on October 1, 2010.

White Canyon’s net assets and comprehensive loss have been excluded from these pro forma financial statements. White Canyon’s primary asset is its investment in DMHC and its remaining net assets are immaterial.

These unaudited pro forma condensed consolidated financial statements are not necessarily indicative of the operating results or financial condition that would have been achieved if the proposed Acquisition had been completed on the dates or for the periods presented, nor do they purport to project the results of operations or financial position of the consolidated entities for any future period or as of any future date. Any potential synergies that may be realized after consummation of the proposed Acquisition, if successful, have been excluded from the unaudited pro forma condensed consolidated financial statement information.

The pro forma adjustments and allocations of the purchase price for DMHC are based on estimates of the fair value of assets acquired and liabilities to be assumed. The final purchase price allocation will be completed after the asset and liability valuations are finalized.

In preparing the unaudited pro forma condensed consolidated statement of financial position and the unaudited pro forma condensed consolidated statements of comprehensive loss, the following historical information, which was prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board, was used:

a. Pro forma statement of financial position as at March 31, 2012 combines the unaudited condensed consolidated statement of financial position of EFI as at March 31, 2012 and the unaudited condensed consolidated statement of financial position of DMHC as at March 31, 2012.

b. Pro forma statement of comprehensive loss for the year ended September 30, 2011 combines the unaudited condensed consolidated statement of comprehensive loss of EFI for the year ended September 30, 2011 (as disclosed in the Company’s December 31, 2011 financial report), the unaudited condensed consolidated statement of comprehensive loss for Titan for the year ended August 31, 2011 (as disclosed in Titan’s November 30, 2011 financial report, which was translated to the U.S. dollar for the period shown using the average exchange rate of 1.0109) and the audited condensed consolidated statement of comprehensive loss of DMHC for the year ended December 31, 2011.

1. Basis of presentation (continued)

c. Pro forma statement of comprehensive loss for the six months ended March 31, 2012 combines the unaudited condensed consolidated statement of comprehensive loss for the six months ended March 31, 2012 of EFI, the unaudited condensed consolidated statement of comprehensive loss for the period beginning on September 1, 2011 and ending on February 28, 2012 of Titan (the construction was based on Titan’s unaudited condensed consolidated statement of comprehensive loss for the three-month period ended November 30, 2011 and Titan’s internal unaudited condensed consolidated statement of comprehensive loss from the period beginning on December 1, 2011 and ending on February 28, 2012, which was translated to the U.S. dollar for the period shown using the average exchange rate of 1.0055) and the constructed pro forma statement of condensed comprehensive loss of DMHC for the six months ended March 31, 2012 (the construction was based on the DMHC’s internal unaudited condensed consolidated statement of comprehensive loss for the three-month period ended December 31, 2011 and the unaudited condensed consolidated statement of comprehensive income for the three months ended March 31, 2012)

The comprehensive loss of DMHC for the three months ended December 31, 2011 has been included in both the pro forma statement of comprehensive loss for the year ended December 31, 2011 and in the six months ended March 31, 2012, respectively.

The unaudited pro forma condensed consolidated statement of financial position and the unaudited pro forma condensed consolidated statements of comprehensive loss should be read in conjunction with the above noted financial statements, including the notes thereto. Certain of DMHC’s assets, liabilities, income and expenses have been reclassified to conform to EFI’s consolidated financial statement presentation.

2. Significant accounting policies

The accounting policies used in preparing the unaudited pro forma condensed consolidated financial statements are consistent with those set out in EFI’s unaudited condensed consolidated financial statements as at December 31, 2011. In preparing the unaudited pro forma condensed consolidated financial statements a review was undertaken by management of EFI to identify accounting policy differences where the impact was potentially material and could be reasonably estimated, to which none were identified. DMHC’s policy with respect to exploration expenditures is to expense these costs as incurred; this difference in accounting policy is not considered to be material by EFI. Accounting differences may be identified after consummation of the proposed Acquisition.

3. Share acquisition of Denison Mines Holding Corp. and White Canyon Uranium Limited

On May 23, 2012 the Company and Denison Mines Corp. (“Denison”) entered into an Arrangement Agreement (“Arrangement”) to complete a transaction whereby EFI will acquire from Denison all of the outstanding shares of DMHC and White Canyon held by Denison. Upon completion of the Arrangement, EFI will hold all of the shares of DMHC and White Canyon, and Denison’s shareholders will in aggregate own approximately 66.5% of the issued and outstanding common shares of EFI.

The obligations of EFI and Denison to complete the Arrangement shall be subject to the satisfaction of the following mutual conditions:

(1) Waiver by Korea Electric Power Corporation (“KEPCO”) to its right of first opportunity.

(2) The assignment of KEPCO’s Offtake Agreement with Denison to EFI or DMHC.

(3) Approval of the Arrangement by Denison shareholders.

(4) Approval of the Arrangement by EFI shareholders.

3. Share acquisition of Denison Mines Holding Corp. and White Canyon Uranium Ltd. (continued)

(5) Approval of the Toronto Stock Exchange and the NYSE MKT, including requisite consents, waivers, permits, exemptions, order and approvals of, and any registrations and filings with any Governmental Entities and other essential parties.

(6) No pending or threatened lawsuits, actions or proceedings by any Governmental Entity, unless previously disclosed.

The Arrangement contains customary deal protection mechanisms, including a break fee payable in certain events, non-solicitation provisions and rights to match a superior proposal.

The cost of the acquisition will include the fair value of the issuance of 425,441,494 EFI common shares (based on the five-day average closing price of $0.25 for the Company’s shares ended May 18, 2012) plus EFI estimated transaction costs of $2,197,975.

The acquisition is expected to be accounted for as a business combination under IFRS. For the purposes of the pro forma statement of financial position, the value of the share consideration has been based on the five-day average closing price of the Company’s shares ended May 18, 2012 (the effective date of presentation of the Acquisition for purposes of the unaudited pro forma statement of financial position). The Company will value the share consideration component based on the closing price of the Company’s shares on the date the Acquisition closes, which may result in an increase or decrease in the consideration for accounting purposes. For every $0.01 change in share price of the Company, the purchase price will change by $4,254,415.

The allocation of the purchase price is based upon management’s preliminary estimates and certain assumptions with respect to the fair value associated with the assets and the liabilities to be acquired. Moreover, this preliminary fair value is supported by an earlier fairness opinion provided to EFI. The actual fair values of the assets and liabilities may differ materially from the amounts disclosed below in the assumed pro forma purchase price allocation as further analysis (including identification of intangible assets, if any, for which no amounts have been estimated and included in the preliminary amounts shown below) is completed. Consequently, the actual allocation of the purchase price is likely to result in different adjustments than those in the unaudited pro forma consolidated statements. EFI will complete a full and detailed valuation of the DMHC assets. Therefore, it is likely that the fair values of assets and liabilities acquired, including mineral properties and property, plant & equipment, will vary from those shown below and the differences may be material.

(1) The book value reported has been adjusted to exclude intercompany accounts.

4. Effect of Acquisition on the unaudited pro forma consolidated financial statements

The unaudited pro forma condensed consolidated financial statements incorporate the following adjustments:

a. An adjustment of $37,923,719 to reflect the excess of the fair value of the assets acquired by EFI over the consideration transferred, which has been recognized as a gain on bargain purchase. The bargain purchase resulted from the share price used in calculating the purchase price decreasing without a subsequent change in the underlying fair value of the DMHC assets and liabilities;

b. An adjustment of $2,197,975 to reflect EFI’s estimated costs and expenses of the transaction. EFI’s transaction costs are comprised of previously deferred costs of $35,552, additional cash costs of $1,189,223, and by the issuance of 4,000,000 EFI common shares having an aggregate market price of $973,200, valued based on the five-day average price the Company’s shares at the date ended May 18, 2012.

c. An adjustment of $106,360,374 to reflect the issuance of 425,441,494 common shares of EFI for the common shares of DMHC and White Canyon;

d. An adjustment of $189,164,457 to eliminate the historical capital stock account of DMHC;

e. An adjustment to eliminate acquired intercompany balances;

g. An adjustment of $50,200 to eliminate DMHC’s accumulated other comprehensive income;

h. An adjustment of $32,625,261 to eliminate DMHC’s goodwill impairment related to its proposed transaction with EFI;

i. An adjustment of $44,079,000 to eliminate DMHC’s impairment of U.S. mining assets related to its proposed transaction with EFI;

j. An adjustment of $242,647 to eliminate DMHC’s intercompany-related consulting income related to Denison’s Mongolia projects;

k. An adjustment of $14,356 to eliminate DMHC’s intercompany-related interest income related to Denison’s Mongolia projects;

l. An adjustment to eliminate DMHC’s intercompany-related interest expense;

m. An adjustment of $558,000 to reflect the increase in the fair value of uranium concentrates; and

n. An adjustment of $2,000,000 to eliminate the historical preferred stock account of DMHC.

5. Pro forma shares outstanding

The average number of shares used in the computation of pro forma basic and diluted loss per share has been determined as follows:

	Six Months Ended March 31, 2012		Year Ended September 30, 2011

FINANCIAL INFORMATION OF DMHC

Schedule 2

INDEPENDENT AUDITOR’S REPORT

To the Directors of Denison Mines Holdings Corp.

We have audited the accompanying consolidated financial statements of Denison Mines Holdings Corp. (the “Company”), which comprise the consolidated statements of financial position as at December 31, 2011, December 31, 2010 and January 1, 2010 and the consolidated statements of income (loss) and comprehensive income (loss), the consolidated statements of changes in equity, and the consolidated statements of cash flow for the years ended December 31, 2011 and December 31, 2010, and the related notes, which comprise a summary of significant accounting policies and other explanatory information.

Management’s responsibility for the financial statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with International Financial Reporting Standards (“IFRS”), and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we comply with ethical requirements and plan and perform the audits to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Denison Mines Holdings Corp. as at December 31, 2011, December 31, 2010 and January 1, 2010 and its results of operations and its cash flows for the years ended December 31, 2011 and December 31, 2010 in accordance with IFRS.

DENISON MINES HOLDINGS CORP.

Notes to the consolidated financial statements for the years ended December 31, 2011 and 2010

(Expressed in U.S. dollars except for shares and per share amounts)

1. NATURE OF OPERATIONS

Denison Mines Holdings Corp. and its subsidiary companies (collectively, the “Company”) are engaged in uranium mining and related activities, including acquisition, exploration and development of uranium bearing properties, extraction, processing and selling of uranium.

The Company has a 100% interest in the White Mesa mill located in Utah, United States and has interests in a number of nearby mines. Uranium, the Company’s primary product, is produced in the form of uranium oxide concentrates (“U₃O₈”) and sold to various customers around the world for further processing. Vanadium, a co-product of some of the Company’s mines is also produced and is in the form of vanadium pentoxide (“V₂O₅ ”). The Company is also in the business of processing uranium bearing waste materials, referred to as “alternate feed materials”.

Denison Mines Holdings Corp. (“DMHC”) is incorporated in the State of Delaware and domiciled in the United States. The address of its registered head office is 1050 17^th Street, Suite 950, Denver, Colorado, United States, 80265. The Company is a wholly owned subsidiary of Denison Mines Corp. (the “Parent”), which holds all of the Company’s common shares either directly or indirectly through White Canyon Uranium Limited (“WCU”), another subsidiary of the Parent. The Parent is a publicly listed corporation incorporated under the Business Corporations Act (Ontario) and domiciled in Canada.

References to “2011” and “2010” refer to the year ended December 31, 2011 and the year ended December 31, 2010 respectively.

2. BASIS OF PRESENTATION AND ADOPTION OF IFRS

The consolidated financial statements are the Company’s first annual financial statements and have been prepared in compliance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board. All adjustments considered necessary by management for fair presentation have been included in these financial statements.

The Company’s presentation currency is U.S dollars.

These financial statements were approved by the board of directors for issue on May 22, 2012.

3. SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used in the preparation of these consolidated financial statements are described below:

(a) Consolidation

The financial statements of the Company consolidate the accounts of DMHC and its subsidiaries. Subsidiaries are those entities which DMHC controls by having the power to govern the financial and operating policies. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether DMHC controls another entity. Subsidiaries are fully consolidated from the date on which control is obtained by DMHC and are de-consolidated from the date that control ceases. Intercompany transactions, balances and unrealized gains and losses from intercompany transactions are eliminated.

(b) Foreign currency translation

(i) Functional and presentation currency

Items included in the financial statements of each entity in the DMHC group are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). Primary and secondary indicators are used to determine the functional currency (primary indicators have priority over secondary indicators). Primary indicators include the currency that mainly influences sales prices and the currency that mainly influences labour, material and other costs. Secondary indicators include the currency in which funds from financing activities are generated and the currency in which receipts from operating activities are usually retained. The U.S. dollar has been determined to be the functional currency for the Company and its subsidiaries.

- 6 -

The consolidated financial statements are presented in U.S. dollars, unless otherwise stated.

(ii) Transactions and balances

Foreign currency transactions are translated into an entity’s functional currency using the exchange rates prevailing at the dates of the transactions. Generally, foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in currencies other than an operation’s functional currency are recognized in the statement of income.

(c) Business combinations

A business combination is defined as an acquisition of assets and liabilities that constitute a business. A business consists of inputs, including non-current assets, and processes, including operational processes, that when applied to those inputs, have the ability to create outputs that provide a return to the Company and its shareholders. A business also includes those assets and liabilities that do not necessarily have all the inputs and processes required to produce outputs, but can be integrated with the inputs and processes of the Company to create outputs.

Business combinations are accounted for using the acquisition method whereby identifiable assets acquired and liabilities assumed, including contingent liabilities, are recorded at 100% of their acquisition-date fair values. The acquisition date is the date the Company acquires control over the acquiree. The Company considers all relevant facts and circumstances in determining the acquisition date.

Acquisition related costs, other than costs to issue debt or equity securities of the acquirer, including investment banking fees, legal fees, accounting fees, valuation fees and other professional or consulting fees are expensed as incurred.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports in its financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, the Company will retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date. The maximum length of time for the measurement period is one year from the acquisition date.

(d) Cash

Cash includes cash on hand and deposits held with banks which are subject to an insignificant risk of changes in value.

(e) Financial instruments

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the financial instrument. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. Financial liabilities are derecognized when the obligations specified in the contract is discharged, cancelled or expires.

At initial recognition, the Company classifies its financial instruments in the following categories:

(i) Financial assets and liabilities at fair value through profit or loss (“FVPL”)

A financial asset or liability is classified in this category if acquired principally for the purpose of selling or repurchasing in the short-term. Financial instruments in this category are recognized initially and subsequently at fair value. Transaction costs are expensed in the consolidated statement of income. Gains and losses arising from changes in fair value are presented in the consolidated statement of income in the period in which they arise.

- 7 -

(ii) Available-for-sale investments

Available-for-sale investments are recognized initially at fair value plus transaction costs and are subsequently carried at fair value. Gains or losses arising from re-measurement are recognized in other comprehensive income. When an available-for-sale investment is sold or impaired, the accumulated gains or losses are moved from accumulated other comprehensive income to the statement of income.

(iii) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and receivables are initially recognized at the amount expected to be received, less a discount (when material) to reduce the loans and receivables to fair value. Subsequently, loans and receivables are measured at amortized cost using the effective interest method less a provision for impairment.

(iv) Financial liabilities at amortized cost

Financial liabilities are initially recognized at the amount required to be paid, less a discount (when material) to reduce the financial liabilities to fair value. Subsequently, financial liabilities are measured at amortized cost using the effective interest method.

The Company has designated its financial assets and liabilities as follows:

• “Restricted cash and investments” are classified as FVPL and any period change in fair value is recorded through the results from operations.

• The Company’s current holdings of equity instruments in “Investments” are classified as available-for-sale and any period change in fair value is recorded through other comprehensive income. When the investment’s value becomes impaired, the loss is recognized in the results of operations in the period of impairment.

• “Cash”, “Trade and other receivables” and “Long-term receivables” are classified as loans and receivables and are measured at amortized cost using the effective interest rate method. Interest income is recorded in net income, as applicable.

• “Accounts payable and accrued liabilities”, “Debt obligations” and “Other liabilities” are classified as other financial liabilities and are measured at amortized cost using the effective interest rate method. Interest expense is recorded in net income, as applicable.

(f) Impairment of financial assets

At each reporting date, the Company assesses whether there is objective evidence that a financial asset (other than a financial asset classified as fair value through profit and loss) is impaired. Objective evidence of an impairment loss includes: i) significant financial difficulty of the obligor; ii) delinquencies in interest or principal payments; iii) increased probability that the borrower will enter bankruptcy or other financial reorganization; and iv) in the case of equity securities, a significant or prolonged decline in the fair value of the security below its cost.

If such evidence exists, the Company recognizes an impairment loss, as follows:

(i) Financial assets carried at amortized cost: The loss is the difference between the amortized cost of the loan or receivable and the present value of the estimated future cash flows, discounted using the instrument’s original effective interest rate. The carrying amount of the asset is reduced by this amount either directly or indirectly through the use of an allowance account.

(ii) Available-for-sale financial assets: The impairment loss is the difference between the original cost of the asset and its fair value at the measurement date, less any impairment losses previously recognized in the statement of income. This amount represents the cumulative loss in accumulated other comprehensive income that is reclassified to net income.

(g) Inventories

Expenditures, including depreciation, depletion and amortization of production assets, incurred in the mining and processing activities that will result in the future concentrate production are deferred and accumulated as ore in stockpiles and in-process and concentrate inventories. These amounts are carried at the lower of average costs or net realizable value (“NRV”). NRV is the difference between the estimated future concentrate price (net of selling costs) and estimated costs to complete production into a saleable form.

- 8 -

Stockpiles are comprised of coarse ore that has been extracted from the mine and is available for further processing. Mining production costs are added to the stockpile as incurred and removed from the stockpile based upon the average cost per ton of ore produced from mines considered to be in commercial production. The current portion of ore in stockpiles represents the amount expected to be processed in the next twelve months.

In-process and concentrate inventories include the cost of the ore removed from the stockpile, a pro-rata share of the amortization of the associated mineral property, as well as production costs incurred to process the ore into a saleable product. Processing costs typically include labor, chemical reagents and directly attributable mill overhead expenditures. Items are valued according to the first-in first-out method (FIFO) or at weighted average cost, depending on the type of inventory or work-in-process.

Materials and other supplies held for use in the production of inventories are carried at average cost and are not written down below that cost if the finished products in which they will be incorporated are expected to be sold at or above cost. However, when a decline in the price of concentrates indicates that the cost of the finished products exceeds net realizable value, the materials are written down to net realizable value. In such circumstances, the replacement cost of the materials may be the best available measure of their net realizable value.

(h) Property, plant and equipment

Property, plant and equipment are recorded at acquisition or production cost and carried net of depreciation and impairments. Cost includes expenditures that are directly attributable to the acquisition of the asset. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. The carrying amount of a replaced asset is derecognized when replaced. Repairs and maintenance costs are charged to the statement of income during the period in which they are incurred.

Depreciation is calculated on a straight line or unit of production basis as appropriate. Where a straight line methodology is used, the assets are depreciated to their estimated residual value over an estimated useful life which ranges from three to fifteen years depending upon the asset type. Where a unit of production methodology is used, the assets are depreciated to their estimated residual value over the useful life defined by management’s best estimate of recoverable reserves and resources in the current mine plan. When assets are retired or sold, the resulting gains or losses are reflected in current earnings as a component of other income or expense. The Company allocates the amount initially recognized in respect of an item of property, plant and equipment to its significant parts and depreciates separately each such part. Residual values, method of depreciation and useful lives of the assets are reviewed at least annually and adjusted if appropriate.

Where straight-line depreciation is utilized, the range of useful lives for various asset classes is generally as follows:

•      Buildings	15 years;
•      Production machinery and equipment	5 - 7 years;
•      Other	3 - 5 years.

(i) Mineral property acquisition, exploration and development costs

Costs relating to the acquisition of acquired mineral rights and acquired exploration rights are capitalized.

Exploration and evaluation expenditures are expensed as incurred on mineral properties not sufficiently advanced. At the point in time that a mineral property is considered to be sufficiently advanced, it is classified as a development mineral property and all further expenditures for the current year and subsequent years are capitalized as incurred. These costs will include costs of maintaining the site until commercial production, costs to initially delineate the ore body, costs for shaft sinking and access, lateral development, drift development and infrastructure development. Such costs represent the net expenditures incurred and capitalized as at the balance sheet date and do not necessarily reflect present or future values.

Once a development mineral property goes into commercial production, the property is classified as “Producing” and the accumulated costs are amortized over the estimated recoverable resources in the current mine plan using a unit of production basis. Commercial production occurs when a property is substantially complete and ready for its intended use.

- 9 -

(j) Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Company’s share of the identifiable net assets of the acquired subsidiary at the date of acquisition. Goodwill is carried at cost less accumulated impairment losses. Impairment losses are recognized in the statement of income when recognized. Goodwill is allocated to each cash generating unit (“CGU”) or group of CGUs that are expected to benefit from the related business combination. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

(k) Impairment of non-financial assets

Property, plant and equipment and intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows or CGUs. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use (being the present value of the expected future cash flows of the relevant asset or CGU, as determined by management). An impairment loss is recognized for the amount by which the CGU’s carrying amount exceeds its recoverable amount.

Goodwill is reviewed for impairment annually or at any time if an indicator of impairment exists.

(l) Reclamation provisions

Reclamation provisions are any legal and constructive obligation related to the retirement of tangible long-lived assets and are recognized when such obligations are incurred, if a reasonable estimate of the value can be determined. These obligations are measured initially at the present value of expected cash flows using a pre-tax discount rate reflecting risks specific to the liability and the resulting costs are capitalized and added to the carrying value of the related assets. In subsequent periods, the liability is adjusted for the accretion of the discount and the expense is recorded in the income statement. Changes in the amount or timing of the underlying future cash flows or changes in the discount rate are immediately recognized as an increase or decrease in the carrying amounts of the related assets and liability. These costs are amortized to the results of operations over the life of the asset. Reductions in the amount of the liability are first applied against the amount of the net reclamation asset on the books with any excess value being recorded in the statement of operations.

The Company’s activities are subject to numerous governmental laws and regulations. Estimates of future reclamation liabilities for asset decommissioning and site restoration are recognized in the period when such liabilities are incurred. These estimates are updated on a periodic basis and are subject to changing laws, regulatory requirements, changing technology and other factors which will be recognized when appropriate. Liabilities related to site restoration include long-term treatment and monitoring costs and incorporate total expected costs net of recoveries. Expenditures incurred to dismantle facilities, restore and monitor closed resource properties are charged against the related reclamation and remediation liability.

(m) Provisions

Provisions for restructuring costs and legal claims, where applicable, are recognized in liabilities when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount can be reliably estimated. Provisions are measured at management’s best estimate of the expenditure required to settle the obligation at the end of the reporting period, and are discounted to present value where the effect is material. The Company performs evaluations to identify onerous contracts and, where applicable, records provisions for such contracts.

(n) Current and Deferred Income tax

Income taxes are accounted for using the liability method of accounting for deferred income taxes. Under this method, the tax currently payable is based on taxable income for the period. Taxable income differs from income as reported in the consolidated statement of income (loss) because it excludes items of income or expense that are taxable or deductible in other periods and it further excludes items that are never taxable or deductible. The Company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the balance sheet date.

- 10 -

Deferred income tax assets and liabilities are recognized based on temporary differences between the financial statement carrying values of the existing assets and liabilities and their respective income tax bases used in the computation of taxable income. Deferred tax liabilities are generally recognized for all taxable temporary differences and deferred tax assets are recognized to the extent that it is probable that taxable income will be available against which deductible temporary differences can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable income nor the accounting income. Deferred tax liabilities are recognized for taxable temporary differences arising on investments in subsidiaries and investments, except where the Company is able to control the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred tax assets are recognized to the extent that taxable income will be available against which the deductible temporary differences can be utilized. The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset realized, based on tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date. Deferred tax is charged or credited to income, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity.

Income tax assets and liabilities are offset when there is a legally enforceable right to offset the assets and liabilities and when they relate to income taxes levied by the same tax authority on either the same taxable entity or different taxable entities where there is an intention to settle the balance on a net basis.

(o) Revenue recognition

Revenue from the sale of mineral concentrates is recognized when it is probable that the economic benefits will flow to the Company and delivery has occurred, the sales price and costs incurred with respect to the transaction can be measured reliably and collectability is reasonably assured. For uranium, revenue is typically recognized when delivery is evidenced by book transfer at the applicable uranium storage facility. For vanadium related products, revenue is typically recognized at the time of shipment to the customer.

Revenue from toll milling services is recognized as material is processed in accordance with the specifics of the applicable toll milling agreement. Revenue and unbilled accounts receivable are recorded as related costs are incurred using billing formulas included in the applicable toll milling agreement.

Revenue from alternate feed process milling is recognized as material is processed, in accordance with the specifics of the applicable processing agreement. In general, the Company collects a recycling fee for receipt of the material and/or receives the proceeds from the sale of any uranium concentrate and other metals produced. Deferred revenues represent processing proceeds received on delivery of materials but in advance of the required processing activity.

(p) Borrowing costs

Borrowing costs attributable to the acquisition, construction or production of qualifying assets are added to the cost of those assets, until such time as the assets are substantially ready for their intended use. All other borrowing costs are recognized as interest expense in the statement of income in the period in which they are incurred.

(q) Accounting standards issued but not yet applied

The Company is currently evaluating the impact of the following pronouncements and has not yet determined the impact of the following pronouncements or whether to early adopt any of the new requirements:

(i) International Financial Reporting Standard 7, Financial Instruments — Disclosure (“IFRS 7”)

IFRS 7 was amended to provide guidelines on the eligibility criteria for offsetting assets and liabilities as a single net amount in the balance sheet. This amendment is effective for annual periods beginning on or after January 1, 2013.

(ii) International Financial Reporting Standard 9, Financial Instruments (“IFRS 9”)

IFRS 9 was issued in November 2009 and contained requirements for financial assets. This standard addresses classification and measurement of financial assets and replaces the multiple category and measurement models in IAS 39 for debt instruments with a new mixed measurement model having only two categories: amortized cost and fair value through profit or loss. IFRS 9 also replaces the models for measuring equity instruments, and such instruments are either recognized at fair value through profit or loss or at fair value through other comprehensive income. Where such equity instruments are measured at fair value through other comprehensive income, dividends are recognized in profit or loss to the extent not clearly representing a return of investment; however, other gains and losses (including impairments) associated with such instruments remain in accumulated comprehensive income indefinitely.

- 11 -

Requirements for financial liabilities were added in October 2010 and they largely carried forward existing requirements in IAS 39, Financial Instruments — Recognition and Measurement, except that fair value changes due to credit risk for liabilities designated at fair value through profit and loss would generally be recorded in other comprehensive income.

This standard is required to be applied for accounting periods beginning on or after January 1, 2015, with earlier adoption permitted.

(iii) International Financial Reporting Standard 10, Consolidated Financial Statements (“IFRS 10”)

IFRS 10 was issued in May 2011 and it establishes principles for the presentation and preparation of consolidated financial statements when an entity controls one or more other entities. IFRS 10 requires an entity to consolidate an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Under existing IFRS, consolidation is required when an entity has the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities. IFRS 10 replaces the consolidation requirements in SIC-12 Consolidation — Special Purpose Entities and IAS 27 Consolidated and Separate Financial Statements. This standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted.

(iv) International Financial Reporting Standard 12, Disclosure of Interest in Other Entities (“IFRS 12”)

IFRS 12 was issued in May 2011 and it is a new and comprehensive standard on disclosure requirements for all forms of interests in other entities, including subsidiaries, joint arrangements, associates and unconsolidated structured entities. The standard carries forward existing disclosures and also introduces significant additional disclosure requirements that address the nature of, and risks associated with, an entity’s interest in other entities. The standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted.

(v) International Financial Reporting Standard 13, Fair Value Measurement (“IFRS 13”)

IFRS 13 was issued in May 2011 and it establishes new guidance on fair value measurement and disclosure requirements for IFRS and completes a major project to improve the convergence of IFRS and US GAAP. The new standard clarifies that fair value is the price that would be received to sell an asset, or paid to transfer a liability in an orderly transaction between market participants, at the measurement date. The standard is effective for annual periods beginning on or after January 1, 2013. Earlier application is permitted.

(vi) International Accounting Standard 1, Presentation of Financial Statements (“IAS 1”)

IAS 1 was amended to require entities to group items within other comprehensive income based on an assessment of whether such items may or may not be reclassified to profit or loss at a subsequent date. This standard is effective for annual periods beginning on or after July 1, 2012. Earlier application is permitted.

(vii) International Accounting Standard 32, Financial Instruments — Presentation (“IAS 32”)

IAS 32 was amended to clarify the criteria that should be considered in determining whether an entity has a legally enforceable right of set off in respect of its financial instruments. Amendments to IAS 32 are applicable to annual periods beginning on or after January 1, 2014 with retrospective application required. Earlier application is permitted.

4. CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS

The preparation of consolidated financial statements in accordance with IFRS requires the use of certain critical accounting estimates and judgements that affect the amounts reported. It also requires management to exercise judgement in applying the Company’s accounting policies. These judgements and estimates are based on management’s best knowledge of the relevant facts and circumstances taking into account previous experience. Although the Company regularly reviews the estimates and judgements made that affect these financial statements, actual results may be materially different.

Significant estimates and judgements made by management relate to:

(a) Depreciation and Amortization of Property, Plant and Equipment

Property, plant and equipment comprise a large component of the Company’s assets and, as such, the depreciation and amortization of those assets have a significant effect on the Company’s financial statements. Depreciation and amortization of property, plant and equipment used in production is calculated on a straight line basis or a unit of production basis as appropriate.

Plant and equipment assets depreciated using a straight-line basis require estimates of residual values and allocate the cost of an asset to production cost evenly over the assets useful life defined as a period of time. Plant and equipment assets depreciated using a units of production basis require estimates of residual values and allocate the cost of an asset to production cost based on current period production in proportion to total anticipated production from the facility.

Mineral property assets are amortized using a units of production basis that allocates the cost of the asset to production cost based on the current period’s mill feed as a proportion of the total estimated resources in the related ore body. The process of making these estimates requires significant judgment in evaluating and assessing available geological, geophysical, engineering and economic data, projected rates of production, estimated commodity price forecasts and the timing of future expenditures, all of which are, by their very nature, subject to interpretation and uncertainty.

Changes in these estimates may materially impact the carrying value of the Company’s property, plant and equipment and the recorded amount of depletion and depreciation.

(b) Valuation of Long-lived Assets

The Company undertakes a review of the carrying values of mining properties and related expenditures whenever events or changes in circumstances indicate that their carrying values may exceed their estimated net recoverable amounts determined by reference to estimated future operating results and discounted net cash flows. An impairment loss is recognized when the carrying value of those assets is not recoverable. In undertaking this review, management of the Company is required to make significant estimates of, amongst other things, future production and sale volumes, forecast commodity prices, future operating and capital costs and reclamation costs to the end of the mine’s life. These estimates are subject to various risks and uncertainties, which may ultimately have an effect on the expected recoverability of the carrying values of the mining properties and related expenditures.

The Company reviews goodwill at least annually. The Company has estimated the fair value of operating segments to which goodwill is allocated using discounted cash flow models that require assumptions about future cash flows, expenditures and an assumed discount rate. Changes in these estimates could have a material impact on the carrying value of the goodwill.

(c) Inventory

The Company values its concentrate, work in process and ore stockpile inventories at the lower of cost or net realizable value at the end of the reporting period. Costs represent the average cost, and include direct labour and materials costs, mine site overhead, plant and equipment depreciation, mineral property amortization and stockpile depletion. Net realizable value is based on estimated future commodity prices and estimated costs required to convert work in process and ore stockpile inventories into saleable form. These estimates are subject to change from period-to-period that may materially impact the carrying value of the Company’s inventories resulting in inventory write-downs and recoveries.

(d) Deferred Tax Assets and Liabilities

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted or substantially enacted tax rates expected to apply when the differences are expected to be recovered or settled. The determination of the ability of the Company to utilize tax loss carry forwards to offset deferred tax liabilities requires management to exercise judgment and make certain assumptions about the future performance of the Company. Management is required to assess whether it is “probable” that the Company will benefit from these prior losses and other deferred tax assets. Changes in economic conditions, commodity prices and other factors could result in revisions to the estimates of the benefits to be realized or the timing of utilizing the losses.

- 13 -

(e) Business Combinations

Management uses judgment in applying the acquisition method of accounting for business combinations and in determining fair values of the identifiable assets and liabilities acquired. The value placed on the acquired assets and liabilities, including identifiable intangible assets, will have an effect on the amount of goodwill that the Company may record on an acquisition. Changes in economic conditions, commodity prices and other factors between the date that an acquisition is announced and when it finally is consummated can have a material difference on the allocation used to record a preliminary purchase price allocation versus the final purchase price allocation which can take up to one year after acquisition to complete.

(f) Reclamation Obligations

Asset retirement obligations are recorded as a liability when the asset is initially constructed. The Company has accrued its best estimate of its share of the cost to decommission its mining and milling properties in accordance with existing laws, contracts and other policies. The estimate of future costs involves a number of estimates relating to timing, type of costs, mine closure plans, and review of potential methods and technical advancements. Furthermore, due to uncertainties concerning environmental remediation, the ultimate cost of the Company’s decommissioning liability could differ from amounts provided. The estimate of the Company’s obligation is subject to change due to amendments to applicable laws and regulations and as new information concerning the Company’s operations becomes available. The Company is not able to determine the impact on its financial position, if any, of environmental laws and regulations that may be enacted in the future.

5. TRANSFER OF URANIUM ENERGY CORPORATION

On June 17, 2011, the Parent’s offer to acquire all of the outstanding shares of WCU closed with 96.98% of shares outstanding accepting the offer. Compulsory acquisition proceedings to acquire the remaining shares of WCU were initiated on June 20, 2011 and were completed in early August 2011.

WCU’s key assets were held through its subsidiary, Uranium Energy Corporation (“UEC”) which had assets located in southeastern Utah, near the Company’s White Mesa mill. Its holdings comprised 100% interests in the Daneros producing mine, the Lark Royal advanced project and the Thompson, Geitus, Blue Jay and Marcy Look exploration projects. UEC commenced production of uranium ore in December 2009 from its 100% owned Daneros uranium mine.

On September 1, 2011, as a result of a group reorganization, the ownership of UEC was transferred from WCU to the Company. Consideration of 4.7 shares valued at $62,270,000 was paid to WCU in return for all of the outstanding shares of UEC.

The reorganization has been accounted for as a transfer of assets between entities under common control. Accordingly, the transaction is excluded from the scope of IFRS 3(R) Business Combinations and the Company has adopted the predecessor values method to account for the transaction. These financial statements have been presented with balance sheet amounts based on amounts recorded by the Parent on June 17, 2011 when the Parent acquired WCU and UEC. It is the Company’s judgment that carrying values as of June 17, 2011 provide the most relevant and reliable information and should be used as the basis for valuation as it reflects that economically, nothing has changed regarding the assets as they were under the same common control both before and after the acquisition by the Company on September 1, 2011. The statement of comprehensive income (loss) includes the results of UEC from June 17, 2011.

Plant and Equipment-Mining

The Company has a 100% interest in the White Mesa mill located in Utah and mines located in Arizona, Colorado and Utah. Mined ore from these mines is processed at the White Mesa mill.

- 17 -

Mineral Properties

The Company has various wholly owned interests in development and exploration projects located in the U.S. Amounts spent on development projects are capitalized as mineral property assets. Exploration projects are expensed.

The most significant of the Company’s mineral property interests are as follows:

The Company has 100% interests in various mines in the Colorado Plateau, Arizona Strip, Henry Mountain and White Canyon mining districts located in Colorado, Arizona and Utah which are either in operations, development or on standby.

On September 1, 2011, the Company acquired certain uranium deposits located in the White Canyon district in Utah in conjunction with the group reorganization which transferred ownership of UEC to the Company (see note 5).

Impairment of Property, Plant and Equipment and Goodwill

As discussed in note 18, the Parent has entered into a proposed transaction with Energy Fuels Inc. (“EFR”) whereby EFR will acquire the Parent’s interest in the Company and WCU in exchange for 425,441,494 common shares of EFR.

The Company identified a potential impairment triggering event as a result of the Parent entering into the proposed transaction with EFR and has therefore undertaken an impairment test on its U.S. mining segment CGU as at December 31, 2011. The Company used a fair value less costs to sell analysis to determine the recoverable amount of this CGU based on the terms of the proposed transaction with EFR. For the purposes of the impairment test, the recoverable amount was based on 425,441,494 common shares of EFR to be received by the Parent and a volume weighted average share price for EFR shares of $0.30 per share.

In performing the impairment test, the Company concluded that the recoverable amount of the CGU was lower than the carrying value. As a result, the Company has recognized a goodwill impairment charge of $32,625,000 and an impairment loss of $44,079,000, allocated on a pro rata basis between plant and equipment and mineral property assets. Each $0.01 decrease (increase) in the EFR share price would have resulted in a corresponding $4,254,000 increase (decrease) in the impairment charge for the CGU.

The transfer of ownership of UEC in 2011 from WCU to the Company was accounted for using the predecessor values method (see note 5) which included goodwill of $32,625,000.

Goodwill impairment

The Company performs an impairment test annually or any time there are impairment indicators for the carrying amounts of its CGUs. Where a CGU has goodwill allocated to it, the goodwill in that CGU must be tested annually for impairment.

As discussed in note 9, the Company performed an impairment test on its U.S. mining segment CGU as at December 31, 2011 using a fair value less costs to sell analysis based on the terms of the proposed transaction with EFR. As a result, the Company has recognized an impairment loss of $32,625,000.

Site Restoration: U.S. Mill and Mines

The decommissioning and reclamation of the White Mesa mill and U.S. mines are subject to legal and regulatory requirements. Estimates of the costs of reclamation are reviewed periodically by the applicable regulatory authorities. The above accrual represents the Company’s best estimate of the present value of future reclamation costs, discounted at rates ranging from 4.98% to 5.67% (2010: 6.19% to 7.17%). As at December 31, 2011, the undiscounted amount of estimated future reclamation costs is $23,082,000 (December 31, 2010: $22,318,000). Reclamation costs are expected to be incurred between 2013 and 2040.

The Company is a party to a revolving credit facility (the “Facility”) with the Parent for up to $125,000,000 subject to an interest rate of LIBOR plus 1.2%. In 2011, the Company drew $12,762,000 on the Facility (2010: $3,671,000), increasing the debt obligation to $116,755,000 at December 31, 2011 (December 31, 2010: $103,993,000). Interest charged on this Facility totaled $1,819,000 in 2011 (2010: $1,707,000) with interest payable of $530,000 at December 31, 2011 (December 31, 2010: $429,000).

The Company also purchased 30,000 pounds of U₃O₈ from DMI in March 2010 for $1,710,000, the fair value of the U₃O₈ on the purchase date.

In 2011, DMI also paid letter of credit fees amounting to $121,000 on behalf of the Company, to facilitate a loan of 150,000 pounds of U₃O₈ from Uranium Participation Corporation (“UPC”), a company managed by DMI in January 2011.

Consideration of $1,935,000 for these purchases and fees remains payable to DMI at December 31, 2011 (December 31, 2010: $1,710,000).

- 24 -

Uranium Participation Corporation

On January 3, 2011, the Company borrowed 150,000 pounds of U₃O₈ from UPC, a company managed by DMI. The loan was made pursuant to a uranium concentrate loan agreement between the parties. As collateral for the loan, DMI issued an irrevocable standby-letter of credit in favour of UPC in the amount of $12,045,000. On March 30, 2011, the Company repaid 150,000 pounds of U₃O₈ to UPC. Loan fees incurred by the Company under the agreement were $91,000. In 2011, the loan fees have been paid and the irrevocable standby-letter of credit has been cancelled.

Compensation of Key Management Personnel

Key management personnel are those persons having authority and responsibility for planning, directing and controlling the activities of the Company, directly or indirectly. Key management personnel includes the Company’s executive officers, vice-presidents and members of its Board of Directors.

The following compensation was awarded to key management personnel:

	Year Ended

(in thousands)	2011		2010
Salaries and short-term employee benefits	$	806	$	949
Key management personnel compensation	$	806	$	949

16. FINANCIAL RISK MANAGEMENT

The Company is exposed to a variety of financial risks: credit risk, liquidity risk, interest rate risk, and price risk. The source of risk exposure and how each is managed is outlined below:

(a) Credit Risk

Credit risk is the risk of loss due to a counterparty’s inability to meet its obligations under a financial instrument that will result in a financial loss to the Company. The Company believes that the carrying amount its cash, trade and other receivables, restricted cash and investments, and long-term receivables represent its maximum credit exposure.

The maximum exposure to credit risk at the reporting dates is as follows:

	December 31		December 31		January 1
(in thousands)	2011		2010		2010
Cash	$	230	$	9,551	$	232
Trade and other receivables		7,940		14,892		2,279
Restricted cash and investments		24,651		20,315		19,564
Long-term receivables		9,595		9,151		8,525
	$	42,416	$	53,909	$	28,716

The Company limits cash and restricted cash and investment risk by dealing with credit worthy financial institutions.

Typically, the majority of the Company’s trade and other receivables balance is related to the sale of mineral concentrates. These sales typically occur to a small number of customers who are credit worthy and with whom the Company has established a relationship with through its past dealings.

Long-term receivables are comprised of amounts receivable from related parties. Operations of these related parties are ultimately funded by the Parent therefore risk of loss from these receivables is limited.

- 25 -

(b) Liquidity Risk

Liquidity risk is the risk that the Company will encounter difficulties in meeting obligations associated with its financial liabilities. The Company’s operations are funded through cash advances, debt obligations and capital contributions from its Parent. A support agreement is in place whereby the Parent has committed to provide financial support to the Company until at least March 31, 2013, or until there is a change in control of the Company.

	Within 1		1 to 5
(in thousands)	Year		Years
Accounts payable and accrued liabilities	$	7,462	$	—
Debt obligations (note 15)		—		116,755
	$	7,462	$	116,755

(c) Interest Rate Risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company is exposed to interest rate risk on its liabilities through its outstanding borrowings and on its assets through its investments in debt instruments. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk.

(d) Price Risk

The Company is exposed to commodity price risk on the commodities it produces and sells. The impact on income (loss) before tax from a 10% increase in the spot prices at December 31, 2011, with all other variables held constant, is as follows:

	Dec.31’2011		Sensitivity
	USD$		USD$ spot		Change in
	spot price		price per		pre-tax net
(in thousands except commodity prices)	per lb		lb increase		income (loss)
Commodity price risk
Uranium		51.75		5.175	$	3,756
Vanadium		5.75		0.575		1,005
					$	4,761

Fair Value of Financial Instruments

IFRS requires disclosures about the inputs to fair value measurements, including their classification within a hierarchy that prioritizes the inputs to fair value measurement. The three levels of the fair value hierarchy are:

• Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities;

• Level 2 — Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and

• Level 3 — Inputs that are not based on observable market data.

The fair value of financial instruments which trade in active markets (such as available-for-sale securities) is based on quoted market prices at the balance sheet date. The quoted market price used to value financial assets held by the Company is the current bid price.

Except as otherwise disclosed, the fair values of cash, trade and other receivables, accounts payable and accrued liabilities, restricted cash and cash equivalents and debt obligations approximate their carrying values as a result of the short-term nature of the instruments, or the variable interest rate associated with the instruments, or the fixed interest rate of the instruments being similar to market rates.

- 26 -

The following table illustrates the classification of the Company’s financial assets within the fair value hierarchy as at December 31, 2011:

	Financial		Fair		December 31, 2011
	Instrument		Value		Fair		Carrying
(in thousands)	Category(1)		Hierarchy		Value		Value
Financial Assets:
Cash		Category C			$	230	$	230
Trade and other receivables		Category C				7,940		7,940
Investments		Category B		Level 1		46		46
Restricted cash and equivalents		Category A		Level 1		24,651		24,651
Long-term receivables		Category C				9,595		9,595
					$	42,462	$	42,462
Financial Liabilities:
Account payable and accrued liabilities		Category D				7,462		7,462
Debt obligations		Category D				116,755		116,755
Other liabilities		Category D				1,935		1,935
					$	126,152	$	126,152

⁽¹⁾  Financial instrument designations are as follows: Category A=Financial assets and liabilities at fair value through profit and loss; Category B=Available for sale investments; Category C=Loans and receivables; and Category D=Financial liabilities at amortized cost.

17. COMMITMENTS AND CONTINGENCIES

General Legal Matters

The Company is involved, from time to time, in various legal actions and claims in the ordinary course of business. In the opinion of management, the aggregate amount of any potential liability is not expected to have a material adverse effect on the Company’s financial position or results.

Performance Bonds and Letters of Credit

In conjunction with various contracts, reclamation and other performance obligations, the Company may be required to issue performance bonds and letters of credit as security to creditors to guarantee the Company’s performance. Any potential payments which might become due under these items would be related to the Company’s non-performance under the applicable contract. As at December 31, 2011, the Company had outstanding bonds of $23,526,000, collateralized by restricted cash and investments of $24,651,000 (see note 8).

Others

The Company has committed to payments under various operating leases and other commitments. The future minimum payments are as follows:

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 30 JUNE 2011

Note 1: Statement of Significant Accounting Policies

These financial statements cover White Canyon Uranium Limited and its controlled entities. White Canyon Uranium Limited is an unlisted public company, incorporated and domiciled in Australia.

Reporting Basis and Conventions

The financial report is a general purpose financial report that has been prepared in accordance with Australian Accounting Standards (including the Australian Accounting Interpretations), other authoritative pronouncements of the Australian Accounting Standards Board and the Corporation Act 2001.

The financial report of the company complies with all Australian equivalents to International Financial Reporting Standards (IFRS) in their entirety. Compliance with AIFRS ensures that the financial report, comprising the financial statements and notes thereto, complies with International Financial Reporting Standards (IFRS).

The financial statements have been prepared on an accruals basis and are based on historical costs unless otherwise stated in the notes. The material accounting policies that have been adopted in preparation of these statements are presented below.

These financial statements were authorised for issue by the Board on 21 May 2012.

(a) Principles of Consolidation

The consolidated financial statements incorporate the assets, liabilities and results of entities controlled by White Canyon Uranium Limited at the end of the reporting period. A controlled entity is any entity over which White Canyon Uranium Limited has the power to govern the financial and operating policies so as to obtain benefits from the entity’s activities. Control will generally exist when the parent owns, directly or indirectly through subsidiaries, more than half of the voting power of an entity. In assessing the power to govern, the existence and effect of holdings of actual and potential voting rights are also considered.

Where controlled entities have entered or left the consolidated entity during the year, the financial performance of those entities are included only for the period of the year that they were controlled.

In preparing the consolidated financial statements, all inter-group balances and transactions between entities in the consolidated entity have been eliminated on consolidation. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with those adopted by the parent entity.

Non-controlling interests, being the equity in a subsidiary not attributable, directly or indirectly, to a parent, are shown separately within the equity section of the consolidated statement of financial position and statement of comprehensive income. The non-controlling interests in the net assets comprise their interests at the date of the original business combination and their share of changes in equity since that date.

(b) Income Tax

The income tax expense (revenue) for the year comprises current income tax expense (income) and deferred tax expense (income).

Current income tax expense charged to the profit or loss is the tax payable on taxable income calculated using applicable income tax rates enacted, or substantially enacted, as at the end of the reporting period. Current tax liabilities (assets) are therefore measured at the amounts expected to be paid to (recovered from) the relevant taxation authority.

Deferred income tax expense reflects movements in deferred tax asset and deferred tax liability balances during the year as well unused tax losses.

Current and deferred income tax expense (income) is charged or credited directly to equity instead of the profit or loss when the tax relates to items that are credited or charged directly to equity.

WHITE CANYON URANIUM LIMITED

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 30 JUNE 2011

Note 1: Statement of Significant Accounting Policies (Cont.)

(b) Income Tax (Cont.)

Deferred tax assets and liabilities are ascertained based on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred tax assets also result where amounts have been fully expensed but future tax deductions are available. No deferred income tax will be recognised from the initial recognition of an asset or liability, excluding a business combination, where there is no effect on accounting or taxable profit or loss.

Deferred tax assets and liabilities are calculated at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates enacted or substantively enacted at the end of the reporting period. Their measurement also reflects the manner in which management expects to recover or settle the carrying amount of the related asset or liability.

Deferred tax assets relating to temporary differences and unused tax losses are recognised only to the extent that it is probable that future taxable profit will be available against which the benefits of the deferred tax asset can be utilised.

Where temporary differences exist in relation to investments in subsidiaries, branches, associates, and joint ventures, deferred tax assets and liabilities are not recognised where the timing of the reversal of the temporary difference can be controlled and it is not probable that the reversal will occur in the foreseeable future.

Current tax assets and liabilities are offset where a legally enforceable right of set-off exists and it is intended that net settlement or simultaneous realisation and settlement of the respective asset and liability will occur. Deferred tax assets and liabilities are offset where a legally enforceable right of set-off exists, the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where it is intended that net settlement or simultaneous realisation and settlement of the respective asset and liability will occur in future periods in which significant amounts of deferred tax assets or liabilities are expected to be recovered or settled.

(c) Plant and Equipment

Each class of plant and equipment is carried at cost of fair value, less, where applicable, any accumulated depreciation and impairment losses. The carrying amount of plant and equipment is reviewed annually by directors to ensure it is not in excess of the recoverable amount from these assets. The recoverable amount is assessed on the basis of the expected net cash flows that will be received from the asset’s employment and subsequent disposal. The expected net cash flows have been discounted to their present values in determining recoverable amounts.

Depreciation

The depreciable amount of all fixed assets is depreciated on the reducing balance method over their useful lives commencing from the time the asset is held ready for use. Leasehold improvements are depreciated over the shorter of either the unexpired period of the lease or the estimated useful lives of the improvements.

The depreciation rates used for each class of depreciable assets are:

Class of Fixed Asset	Depreciation Rate
Furniture and Fixtures	15%
Plant and Equipment	15% - 33.3%
Leasehold Improvements	12%

The asset’s residual values and useful lives are reviewed and adjusted, if appropriate, at the end of each reporting period.

WHITE CANYON URANIUM LIMITED

NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 30 JUNE 2011

Note 1: Statement of Significant Accounting Policies (Cont.)

(c) Plant and Equipment (Cont.)

An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount.

Gains and losses on disposals are determined by comparing proceeds with the carrying amount. These gains and losses are included in the statement of comprehensive income.

(d) Exploration and Development Expenditure

Exploration and evaluation incurred is accumulated in respect of each identifiable area of interest. These costs are only carried forward to the extent that they are expected to be recouped through the successful development of the area of interest or sale of that area of interest, or exploration and evaluation activities have not reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves and active or significant operations in, or in relation to, the area of interest are continuing.

Accumulated costs in relation to an abandoned area are written off in full against profit in the year in which the decision to abandon the area is made.

A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward cots in relation to the area of interest.

(e) Impairment of Assets

At the end of each reporting period, the directors review the carrying values of its tangible and intangible assets to determine whether there is any indication that those assets have been impaired. If such an indication exists, the recoverable amount of the asset, being the higher of the asset’s fair value less costs to sell and value in use, is compared to the asset’s carrying value. Any asset’s carrying value over its recoverable amount is expensed to the statement of comprehensive income.

Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

(f) Inventories

Inventories are valued at the lower of cost and net realisable value.

Cost comprises direct material, labour and expenditure in getting such inventories to their existing location and condition, based on weighted average costs incurred during the period in which such inventories were produced.

Net realisable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale.

Note 1: Statement of Significant Accounting Policies (Cont.)

(g) Mine Properties

Mine properties represent the accumulation of all acquisition, exploration, evaluation and development expenditure incurred by or on behalf of the company in relation to areas of interest in which mining of mineral resource has commenced. When further development expenditure, is incurred in respect of a mine property after the commencement of production, such expenditure is carried forward as part of the cost of that mine property only when substantial future economic benefits are established, otherwise such expenditure is classified as part of the cost of production.

Amortisation is provided on the units-of-production method, with separate calculations being made for each mineral resource. Estimated future capital costs to be incurred in accessing the reserves and measured resources are taken into account in determining amortisation charges. The units-of-production method results in an amortisation charge proportional to the depletion of the economically recoverable mineral resources.

A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward costs in relation to that area of interest. Should the carrying value of the expenditure not yet amortised exceed its estimated recoverable amount in any year, the excess is written off to the statement of comprehensive income.

(h) Rehabilitation costs

Long-term environmental obligations are based on the company’s environmental management plans, in compliance with current environmental and regulatory requirements.

Full provision is made based on the net present value of the estimated cost of restoring the environmental disturbance that has occurred up to the reporting date. Increases due to additional environmental disturbances, relating to the development of an asset, are capitalised and amortised over the remaining lives of the area of interest.

The estimated costs of rehabilitation are reviewed annually and adjusted as appropriate for changes in legislation, technology or other circumstances. Cost estimates are not reduced by potential proceeds from the sale of assets.

(i) Leases

Lease payments for operating leases, where substantially all the risks and benefits remain with the lessor, are charged as expenses in the periods in which they are incurred.

(j) Foreign Currency Transactions and Balances

Functional and Presentation Currency

The functional currency of each of the entities in the consolidated entity is measured using the currency of the primary economic environment in which that entity operates. The consolidated financial statements are present in Australian dollars which is the parent entity’s functional and presentation currency.

Transactions and Balances

Foreign currency transactions are translated into functional currency using the exchange rates prevailing at the date of the transaction. Foreign currency monetary items are translated at the year-end exchange rate. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date when fair values were determined.

Exchange differences arising on the translation of monetary items are recognised directly in the statement of comprehensive income except where deferred in equity as a qualifying cash flow or net investment hedge. Exchange differences arising on the translation of non-monetary items are recognised directly in equity to the extent that the gain or loss is directly recognised in equity, otherwise the exchange difference is recognised in the statement of comprehensive income.

FOR THE YEAR ENDED 30 JUNE 2011

Note 1: Statement of Significant Accounting Policies (Cont.)

(j) Foreign Currency Transactions and Balances (Cont.)

Group companies

The financial results and position of foreign operations whose functional currency is different from the presentation currency are translated as follows:

• assets and liabilities are translated at year-end exchange rates prevailing at that reporting date;

• income and expenses are translated at average exchange rates for the period; and

• retained earnings are translated at the exchange rates prevailing at the date of the transaction.

Exchange differences arising on translation of foreign operations are transferred directly to the foreign currency translation reserve in the statement of comprehensive income. These differences are recognised in the statement of comprehensive income in the period in which the operation is disposed.

(k) Employee Entitlements

Liabilities for employee benefits for wages, salaries and annual leave expected to be settled within 12 months of the year end represent present obligations resulting from employees services provided to reporting date, calculated at the undiscounted amounts based on remuneration wage and salary rates that the company expects to pay as at reporting date including related on-costs.

Provision is made for the company’s liabilities for employee’s annual leave benefits arising from service rendered by employees to balance date.

Equity-settled compensation

The company operates equity-settled share-based payment employee share and option schemes. The fair value of the equity to which employees become entitled is measured at grant date and recognised as an expense over the vesting period, with a corresponding increase to an equity account. The fair value of shares is ascertained as the market bid price. The fair value of options is ascertained using a valuation model which incorporates all market vesting conditions. The number of shares and options expected to vest is reviewed and adjusted at the end of each reporting date such that the amount recognised for services received as consideration for the equity instruments granted shall be based on the number of equity instruments that eventually vest.

(l) Cash and Equivalents

Cash and equivalents include cash on hand, deposits held at call with banks and other short term highly liquid investments. For the purpose of the statement of cash flows, cash includes deposits at call, which are readily convertible to cash on hand and subject to an insignificant risk of changes in value.

(m) Revenue

Sales of goods

Revenue is recognised when the significant risks and rewards of ownership of the goods have passed to the buyer and can be measured reliably.

Interest

Interest revenue is recognised on a proportional basis taking into account the interest rates applicable to the financial assets.

All revenue is stated net of the amount of goods and services tax (GST)

(n) Goods and Services Tax (GST)

Revenues, expenses and assets are recognised net of the amount of GST, except where the amount of GST incurred is not recoverable from, or payable to, the ATO, is included as a current asset or liability in the statement of financial position.

Cash flows are included in the statement of cash flows on a gross basis except for the GST component of investing and financing activities, which are disclosed as operating cash flows.

(o) Comparative Figures

When required by Accounting Standards, comparative figures have been adjusted to conform to changes in presentation for the current financial year.

Critical Accounting Estimates and Judgements

The directors evaluate estimates and judgements incorporated into the financial report based on historical knowledge and best available current information. Estimates assume a reasonable expectation of future events and are based on current trends and economic data, obtained both externally and within the company.

The areas that may have a significant risk of causing a material adjustment to the carrying amounts of certain assets and liabilities within the next annual reporting period are:

Exploration and evaluation expenditure

The board of directors determines when an area of interest should be abandoned. When a decision is made that an area of interest is not commercially viable, all costs that have been capitalised in respect of that area of interest are written off. The Directors’ decision is made after considering the likelihood of finding commercially viable reserves.

No areas of interest have been abandoned at the date of this report.

Determination of mineral resources and ore reserves

The company estimates its mineral resources and ore reserves in accordance with the Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2004 (the ‘JORC code’). The information on mineral resources and ore reserves were prepared by or under the supervision of Competent Persons as defined in the JORC code. The amounts presented are based on the mineral resources and ore reserves determined under the JORC code.

There are numerous uncertainties inherent in estimating mineral resources and ore reserves and assumptions that are valid at the time of estimation may change significantly when new information becomes available.

Changes in the forecast prices of commodities, exchange rates, production costs or recovery rates may change the economic status of reserves and may, ultimately, result in the reserves being restated. Such changes in the reserves could impact on depreciation and amortisation rates, asset carrying values, deferred stripping costs and provisions for decommissioning and restoration.

Impairment of capitalised mine development expenditure

The future recoverability of capitalised mine development expenditure is dependent on a number of factors, including the level of proved, probable and inferred mineral resources, future technological changes which could impact the cost of mining, future legal changes (including changes to environmental restoration obligations) and changes to commodity prices.

To the extent that capitalised mine development expenditure is determined not to be recoverable in the future, this will reduce profits and net assets in the period in which this determination is made.

Environmental Issues

Balances disclosed in the financial statements and notes thereto are not adjusted for any pending or enacted environmental legislation, and the directors understanding thereof. At the current stage of the company’s development and its current environmental impact the directors believe such treatment is reasonable and appropriate.

Management’s objectives when managing capital is to ensure the croup continues as a going concern, so that they may continue to provide returns for shareholders and benefits for other stakeholders.

Due to the nature of the company’s activities, being mineral exploration, the company does not have ready access to credit facilities, with the primary source of funding being equity raisings. Therefore, the focus of the company’s capital risk management is the current working capital position against the requirements of the company to meet exploration programmes and corporate overheads.

(b) Sensitivity Analysis

At 30 June 2011, if interest rates had changed by -/+ 200 basis points from the weighted average rate for the year with all other variables held constant, post-tax loss for the company would have been $24,674 lower/higher respectively (2010—$16,275) lower/higher respectively) as a result of lower/higher interest income from cash and cash equivalents.

(c) Foreign Currency Risk

The company is exposed to fluctuations in foreign currencies arising from the purchase of goods and services in currencies other than the company’s measurement currency.

(d) Credit Risk

The maximum exposure to credit risk, excluding the value of any collateral or other security, at reporting date to recognised financial assets is the carrying amount as disclosed in the statement of financial position and the notes to the financial statements. The company does not have any material credit risk exposure to any single receivable or group of receivables under financial instruments entered into by the company.

Credit risk related to balances with banks and other financial institutions is managed by the company in accordance with approved Board policy. Such policy requires that surplus funds are only invested with counterparties with a Standard and Poor’s rating of at least AA-. The following table provides information regarding the credit risk relating to cash and money market securities based on Standard and Poor’s counterparty credit ratings.

	Note	2011		2010

Cash and cash equivalents
- AA Rated	7		1,233,712		813,737

No material exposure is considered to exist by virtue of the possible non performance of the counterparties to financial instruments and cash deposits.

(e) Net Fair Values

The net fair value of financial assets and liabilities of the company approximated their carrying amount.

The company has no financial assets and liabilities where the carrying amount exceeds the net fair value at balance date.

The aggregate net fair values and carrying amounts of financial assets and financial liabilities are disclosed in the statement of financial position and notes to the financial statements.

Note 23: Financial Risk Management (Cont.)

(f) Liquidity Risk

Liquidity risk arises from the possibility that the company might encounter difficulty in settling its debts or otherwise meeting its obligations related to financial liabilities. The company manages this risk through the following mechanisms:

• preparing forward looking cash flow analysis in relation to its operational, investing and financing activities

• obtaining funding from a variety of sources

• maintaining a reputable credit profile

• managing credit risk related to financial assets

• investing only in surplus cash with major financial institutions

• comparing the maturity profile of financial liabilities with the realisation profile of financial assets

The company does not have a significant exposure in terms of financial liabilities or illiquid financial assets and is able to settle its debts or otherwise meet its obligations related to financial liabilities. Financial asset and financial liability are expected to mature within 30 days.

(g) Price Risk

Price risk relates to the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices largely due to demand and supply factors for commodities. As at 30 June 2011 and 30 June 2010, the company is not exposed to equity securities price risk or commodity price risk.

Note 24: Events subsequent to the end of the reporting period

Effective 1 September 2011, the intercompany loan balances totaling US$30,388,871 between White Canyon (the “Company”) and its wholly owned subsidiary, Utah Energy Corporation were converted into a capital contribution by the Company to UEC.

Report on the Financial Report

We have audited the accompanying financial report of White Canyon Uranium Limited, which comprises the consolidated statement of financial position as at 30 June 2011, and the consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended, notes comprising a summary of significant accounting policies and other explanatory information, and the directors’ declaration of the consolidated entity comprising the company and the entities it controlled at the year’s end or from time to time during the financial year.

Directors’ Responsibility for the Financial Report

The directors of the company are responsible for the preparation of the financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the financial report that is free from material misstatement, whether due to fraud or error. In Note 1, the directors also state, in accordance with Accounting Standard AASB 101 Presentation of Financial Statements, that the financial statements comply with International Financial Reporting Standards.

Auditor’s Responsibility

Our responsibility is to express an opinion on the financial report based on our audit. We conducted our audit in accordance with Australian Auditing Standards. These Auditing Standards require that we comply with relevant ethical requirements relating to audit engagements and plan and perform the audit to obtain reasonable assurance about whether the financial report is free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial report. The procedures selected depend on the auditor’s judgement, including the assessment of the risks of material misstatement of the financial report, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial report in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by the directors, as well as evaluating the overall presentation of the financial report.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

COMMENTS BY AUDITOR FOR CANADIAN READERS ON REPORTING DIFFERENCES

BETWEEN CANADIAN GENERALLY ACCEPTED AUDITING STANDARDS AND

AUSTRALIAN AND INTERNATIONAL STANDARDS ON AUDITING

To the Directors of White Canyon Uranium Limited

We conducted our audit for the 12 months ended 30 June 2011 and 30 June 2010 in accordance with Australian Auditing Standards and International Standards on Auditing. There are no material differences in the form or content of our report (except as noted in the paragraph below) as compared to an auditor’s report prepared in accordance with Canadian Generally Accepted Auditing Standards (GAAS) and if this report was prepared in accordance with Canadian GAAS, it would not contain a reservation.

Canadian GAAS requires that an auditor’s opinion state that the consolidated financial statements of the company present fairly, in all material respects, the financial position of the consolidated entity as at year end and its results of operations and cash flows for the year then ended. In Australia, reporting standards for auditors require that an auditor’s opinion state that the consolidated financial statements of the company give a true and fair view of the consolidated entity’s financial position as at year end and of its performance for the year then ended.
