FORWARD-LOOKING STATEMENTS

This Annual Information Form (“AIF”), and the documents incorporated by reference herein, contain “forward-looking information” within the meaning of securities legislation, including the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation, and are collectively referred to herein as “forward-looking statements”.  These forward-looking statements are made as of the date of this AIF or, in the case of documents incorporated by reference herein, as of the date of such documents. Other than as specifically required by applicable securities laws, the Company does not intend, and does not assume any obligation, to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made, or to reflect the occurrence of unanticipated events, whether as a result of new information, future events or results or otherwise.

Forward-looking statements are based on the opinions and estimates of management as of the date such statements are made and represent management’s best judgment based on facts and assumptions that management considers reasonable.  The material assumptions upon which such forward-looking statements are based include, among others:  that the demand for gold and base metal deposits will develop as anticipated; that the price of gold will remain at levels that will render the Phoenix Gold Project (as hereinafter defined) economic; that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, interruption in transportation or utilities, or adverse weather conditions; that the Company will meet its estimated timeline for the development of the Phoenix Gold Project; that the Company will continue to have the ability to attract and retain skilled staff; that the mineral resource estimate as disclosed in the Technical Report (as hereinafter defined) will be realized; and that there are no material unanticipated variations in the cost of energy or supplies, or in the pre-production capital and operating cost estimate as disclosed in the Technical Report.  The Company makes no representation that reasonable business people in possession of the same information would reach the same conclusions.

Page 2

Forward-looking statements in this document include, but are not limited to statements regarding the Company’s plans in respect of the development of the Phoenix Gold Project, costs and timing of the development of new deposits, success of exploration and development activities, permitting time lines, currency fluctuations, requirements for additional capital, government regulation of exploration operations, environmental risks, unanticipated reclamation expenses and title disputes or claims.  In certain cases, forward-looking statements can be identified by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved”.

Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.  Such factors include, among others: future prices of gold and other metals; possible variations in mineralization, grade or recovery rates; actual results of current exploration activities; actual results of reclamation activities; conclusions of future economic evaluations; changes in project parameters as plans continue to be refined; failure of equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays and other risks related to joint venture operations; timing and receipt of regulatory approvals of operations; the ability of the Company and other relevant parties to satisfy regulatory requirements; the availability of financing for proposed transactions and programs on reasonable terms; the ability of third-party service providers to deliver services on reasonable terms and in a timely manner; and delays in the completion of development or construction activities. Other factors that could cause the actual results to differ include market prices, results of exploration, availability of capital and financing on acceptable terms, inability to obtain required regulatory approvals, unanticipated difficulties or costs in any rehabilitation which may be necessary, market conditions and general business, economic, competitive, political and social conditions, as well as those factors discussed in the section titled “Risk Factors” in this AIF.

Although management of the Company has attempted to identify important factors (which it believes are reasonable) that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.  There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

CAUTION REGARDING ADJACENT OR SIMILAR MINERAL PROPERTIES

This AIF contains information with respect to adjacent or similar mineral properties in respect of which the Company has no interest or rights to explore or mine. The Company advises US investors that the mining guidelines of the US Securities and Exchange Commission (the “SEC”) set forth in the SEC’s Industry Guide 7 strictly prohibit information of this type in documents filed with the SEC. The Company is exempt from the requirements of Industry Guide 7 pursuant to the Canada-US Multi-Jurisdictional Disclosure System. Readers are cautioned that the Company has no interest in or right to acquire any interest in any such properties, and that

Page 3

mineral deposits on adjacent or similar properties are not indicative of mineral deposits on the Company’s properties.

CAUTION REGARDING REFERENCE TO RESOURCES AND RESERVES

National Instrument 43-101 Standards of Disclosure of Mineral Projects (“NI 43-101”) is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  The disclosure in this AIF, including the documents incorporated herein by reference, uses terms that comply with reporting standards in Canada. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource”, “inferred mineral resource”, “probable mineral reserve” and “proven mineral reserve” are defined in and required to be used by the Company by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into mineral reserves.  “Inferred mineral resources” have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility studies, pre-feasibility studies or other economic studies, except in prescribed cases, such as in a preliminary economic assessment under certain circumstances. It cannot be assumed that all or any part of the measured mineral resources, indicated mineral resources or inferred mineral resources will ever be upgraded to a higher category.

Accordingly, information contained in this AIF and the documents incorporated by reference herein containing descriptions of the Company’s mineral deposits may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

CAUTION REGARDING HISTORICAL RESULTS

Historical results of operations and trends that may be inferred from the discussion and analysis in this AIF may not necessarily indicate future results from operations.  In particular, the current state of the global securities markets may cause significant reductions in the price of the Company’s securities and render it difficult or impossible for the Company to raise the funds necessary to continue operations. See “Risk Factors – Market Price of Company’s Shares and Financing”.

Resources/Reserves Definitions

“Indicated Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

“Inferred Mineral Resource” is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

“Measured Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

“Mineral Reserve” is the economically mineable material derived from a Measured and/or Indicated Mineral Resource. It is inclusive of diluting materials and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, including consideration of and modification by, realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified. Mineral Reserves are subdivided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves.

“Mineral Resource” is a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction.  The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge.

Page 11

“Probable Mineral Reserve”is the economically mineable material derived from a Measured and, in some circumstances, an Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. It is estimated with a lower level of confidence than a Proven Mineral Reserve. It is inclusive of diluting materials and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out and, including consideration of and modification by, realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

“Proven Mineral Reserve”is the economically mineable material derived from a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. It is estimated with a high level of confidence.  It is inclusive of diluting materials and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, including consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified.

GENERAL DEVELOPMENT OF THE BUSINESS

Three Year History

2009

In 2009, rehabilitation of existing underground levels was completed at the Phoenix Gold Project and the hoist and shaft were successfully re-commissioned. Rubicon continued drilling from the surface and commenced underground drilling in June from the 122 metre level. A total of 69,654 metres of drilling was completed on the Phoenix Gold Property in 2009.

The majority of the drilling (61,632 metres) was carried out on the F2 Gold System from three underground drill stations from the 122 metre level (400 foot level), which was supplemented by drilling with two rigs from surface.

Shaft sinking to a depth of 305 metres (1,001 feet) was commenced. The total drilling and underground development costs were $23.1 million.  Positive results continued the trend established in 2008, confirming further expansion of the F2 Gold System.

During the first quarter of 2009, the Company initiated programs to rehabilitate and dewater the historic shaft and underground workings under an Advanced Exploration permit that was secured on February 27, 2009.

In order to reach its goals, the Company initiated engineering studies, environmental studies and applications to utilities supporting advanced exploration and preparing the Phoenix Gold Property for potential exploitation.

Page 12

On March 5, 2009, the Company closed a $40 million bought deal private placement financing for common shares.  As a result, the Company announced plans to expand and accelerate its 2009 exploration program to 80,000 metres of drilling with further emphasis on underground drilling and associated development work.

During May of 2009, the Company received an additional $16.4 million from the exercise of warrants.  This was followed in July of 2009 by the Company’s announcement of plans for up to an additional 20,000 metres of drilling, property wide, to test additional drill targets.

During the summer of 2009, the Company assessed its plans for its Phoenix Gold Project based on the successful results received as of that time. As confirmed in its October 8, 2009 NI 43-101 technical report, it was determined that an expanded scope and budget for drilling was warranted.

On November 12, 2009, the Company closed a public offering for net proceeds of $82 million.  The use of these proceeds included an additional 120,000 metres of drilling on the F2 Gold System during the period 2010 and 2011 and underground excavation (drifting) to directly access parts of the gold system. The Company indicated its plans to take a bulk sample as part of the program subject to results from local delineation drilling.

2010

From January 1, 2010 to December 31, 2010, the Company completed a total of 155,134 metres of drilling and 3,907 metres of underground development at a total cost of $57.9 million.  A total of 135,819 metres of this drilling was focussed on the F2 Gold System.

In January of 2010, Rubicon entered into an Exploration Accommodation Agreement with the Lac Seul First Nation covering all pre-production work in respect of certain of Rubicon’s Red Lake area properties, including the Phoenix Gold Property, which are located on lands considered by the Lac Seul First Nation to be within its traditional territory. Rubicon secured the support of Lac Seul First Nation for the Phoenix Gold Project and its other Red Lake projects in return for certain benefits and accommodations. Consultations with First Nations whose traditional territory includes Red Lake continue.

In April of 2010, the Company was awarded the Northwestern Ontario Developer of the Year Award. The award was presented by the Northwestern Ontario Prospectors Association and recognizes “an outstanding Northwestern Ontario developer or development project during the previous calendar year”.  The award recognizes the collective efforts and achievements of Rubicon’s staff at the Phoenix Gold Project.

On July 12, 2010, the Company announced that preliminary metallurgical test work performed on several composite samples from the Phoenix Gold Project returned gold recoveries averaging 93.8%, an absence of any refractory gold component, despite the presence of appreciable sulphide minerals in the sampled gold zones and contained low arsenic content.  The samples are amenable to standard gravity and carbon-in-leach treatments.  The Company considered these results highly encouraging and undertook work designed for optimization of both future capital and operating costs.  Results were preliminary in nature with considerably more sample material and test work required to further characterize and optimize the F2 Gold System metallurgy.

On September 29, 2010, the Company filed a short form prospectus to qualify the secondary offering by Evanachan Limited (“Evanachan”) and McEwen Trading LP (together, the “Selling Shareholders”) of an aggregate of 45,714,357 common shares of the Company at a price of $4.16 per share (the “Secondary Offering”).

The Selling Shareholders were entities owned or controlled by Robert R. McEwen, who had beneficial ownership of the shares owned by Evanachan and control and direction over the shares owned by McEwen Trading.  The Company was not entitled to any of the proceeds from the sale of such shares.  All expenses incurred in connection with the preparation and filing of the short form prospectus were paid by GMP Securities L.P.

The Selling Shareholders previously held 21.4% of the then issued and outstanding common shares of the Company.  After giving effect to the Secondary Offering, the Selling Shareholders confirmed that neither of them any longer owned any of the issued and outstanding common shares of the Company.  The Secondary Offering closed on October 5, 2010.  See “Material Contracts”.

In connection with the Secondary Offering, a NI 43-101 technical report was filed that summarized the Company’s exploration work completed on the Phoenix Gold Property up to July 31, 2010.  The report recommended that the Company continue to pursue its current exploration program (of which approximately $27.6 million remained to be spent between July 31, 2010 and the end of Q1 2011) and that it consider undertaking a preliminary resource and/or assessment of the geological potential prior to commencing its next phase of exploration and development.

Further third party studies were initiated by the Company in 2010. A paste fill study was conducted in parallel with the mining study (initially commenced in 2009) and was completed at the end of September 2010.

On November 29, 2010, the Company announced the first inferred gold resource and geological potential estimates for the Phoenix Gold Project, F2 Gold System. The estimates were prepared by Geoex Limited (“Geoex”) based on 166,886 metres of diamond drilling in 237 drill holes carried out between February 27, 2008 (the date of the initial discovery of the F2 Gold System) and July 31, 2010.  The estimates were contained in a technical report prepared by Geoex and filed on SEDAR on January 11, 2011. The estimates and technical report were subsequently replaced and superseded by: (i) the Company’s announcement of March 31, 2011, and (ii) the Amended Report, as defined below, filed on SEDAR on April 11, 2011.

On December 15, 2010, the Company announced that its Phoenix Gold Project team was awarded the Association for Mineral Exploration, British Columbia, Colin Spence Award for excellence in global mineral exploration.  The award was given for its role in the discovery and development of the F2 Gold System in Red Lake, Ontario.

On December 21, 2010, the Company announced the commencement of taking a bulk sample within part of the core area of the F2 Gold System.

Page 14

2011

In early January, the Company announced further drill results from exploration drilling of the Phoenix Gold Project and specifically the F2 Gold System. The results were significant in that they showed development of the F2 Gold System below the current area of exploration drilling. Also referred to as “delineation drilling” in the Company’s announcements and releases, this exploration drilling was carried out to gain a better understanding of the structure and extent of the deposit.

In March 2011, the Company notified Kiska Metals Corporation (“Kiska”, formerly Rimfire Minerals Corporation) that the Company was terminating the option it held on the Alaska claims that were the subject of the option.  For more details, please refer to the section of this AIF entitled “U.S. Projects”.

On March 31, 2011, the Company announced amended inferred mineral resource and geological potential estimates for the Phoenix Gold Project, F2 Gold System. These amended estimates were prepared by Peter George of Geoex and resulted from a review by the British Columbia Securities Commission of the technical report prepared by Geoex and filed on SEDAR on January 11, 2011. The amended estimates replaced and superseded the estimates announced by the Company on November 29, 2010 and contained in the January 11, 2011 technical report.

On April 8, 2011, the Company announced an update on its exploration drill program for the Phoenix Gold Project, F2 Core Zone. At that time, a total of 16,000 metres of  the Company’s planned 27,000 metre exploration drill program had been completed. The results of that initial exploration drilling continued to define the presence of northeast-trending (F1) gold mineralization associated with silicification, quartz veining and strong alteration within, and adjacent to, favourable host rock types. The final exploration drilling results were announced by the Company on June 1, 2011 by way of news release.

On April 11, 2011, the Company announced the filing of an amended NI 43-101 technical report (the “Amended Report”) containing amended inferred mineral resource and geological potential estimates and confirmed that the amended estimates contained therein amended and superseded the estimates announced by the Company on November 29, 2010 and which were the subject of the January 11, 2011 technical report.

In May and September 2011, the Company provided updates on its underground ‘9X’ exploration drill program carried out on the F2 Gold System at the Phoenix Gold Project. The details with respect to that updated information are set out in the news releases issued by the Company on May 12, 2011 and September 12, 2011, which are available for review on SEDAR at www.sedar.com.

As announced on June 27, 2011, the Company granted West Kirkland Mining Inc. (“West Kirkland”) the right to earn a majority interest in certain mineral rights held by the Company in the State of Nevada by spending US$15 million over four years.  If such a majority interest is earned by West Kirkland, the Company would still retain a significant interest in any future discovery.  For more details, please refer to the section of this AIF entitled “U.S. Projects”.

On June 29, 2011, the Company announced the results of a Preliminary Economic Assessment for its Phoenix Gold Project, F2 Gold System, which was prepared by AMC, with metallurgical sections prepared by Soutex. Both AMC and Soutex are independent of the Company.  The Technical Report, which was filed on SEDAR on August 11, 2011, disclosed the results of the Preliminary Economic Assessment and updated the mineral resources stated in the Amended Report.  For more details, please refer to sections of this AIF entitled “Material Mineral Projects” and “Documents Incorporated By Reference”, namely the Technical Report.

Page 15

The PEA was based on an updated mineral resource estimate containing an Indicated Mineral Resource of 1,028,000 tonnes grading 14.5 g/t gold (477,000 ounces of gold) and an Inferred Mineral Resource of 4,230,000 tonnes grading 17.0 g/t gold (2,317,000 ounces of gold).  Inferred resources are too speculative to have economic considerations applied to them and there is no certainty that the inferred resources will be converted to measured or indicated resources.

The PEA indicated that the F2 Gold System is a potentially viable project capable of producing a steady state average of 180,000 ounces of gold per year and over 200,000 ounces at its peak using conventional mining and processing techniques with an initial capital investment of $214 million (including a 30% contingency).

While the PEA is preliminary in nature, and includes inferred minerals resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, the Company was encouraged by the results of the PEA and the potential viability of the F2 Gold System as a producing project.

In respect of development at the Phoenix Gold Project in 2011, the Company completed lateral development of 1,222 metres and vertical development of 134 metres. The majority of the lateral development was to establish an additional drill platform and included the start of a new drift towards a new drill station and the start of a new level. The vertical component of the development was the completion of a waste pass.

In addition to the foregoing, hoist foundation civil work was completed and assembly of the double drum hoist began. The Company commissioned the surface substation for receipt of electrical power and voice and data lines were installed to service the project site. In this regard, the Company received and accepted offers to connect from Hydro One Networks Inc. (“Hydro One”) for a total of 5.3MW of electrical power.

On July 28, 2011, the Company announced the completion of the purchase by Agnico-Eagle Mines Limited (“Agnico-Eagle”) of 21,671,827 common shares of the Company at a price of $3.23 per common share for proceeds to the Company of approximately $70,000,000. As a result of this private placement, Agnico-Eagle became the owner of 9.2% of the then issued and outstanding shares of the Company.

In August 2011, Franco-Nevada Corporation (“Franco-Nevada”) purchased all of the right, title and interest of Dominion Goldfields Corporation (“Dominion Goldfields”) in the 2% net smelter returns royalty payable on that part of the Company’s Phoenix Gold Project lying beneath the waters of Red Lake, Ontario (and excluding mining properties covering the land portion of the Phoenix Gold Project).

In September 2011, the Company announced the appointment of Mr. Michael Winship as a director of the Company.

The Company announced on October 25, 2011 that, by exercising a right of first refusal, it acquired, and thereby extinguished, the 3% net smelter returns royalty payable on the mining properties covering the land portion of the Company’s Phoenix Gold Project. This acquisition was separate and apart from the acquisition by Franco-Nevada of the 2% net smelter returns in August 2011 as described above. Consideration for this transaction was the issuance of 1,216,071 of the Company’s common shares at a deemed price per share of $3.50, for total consideration of $4,256,249.

Page 16

On December 2, 2011, the Company announced that the Ontario Ministry of Northern Development and Mines had accepted the Company’s Production Closure Plan for the Phoenix Gold Project. This approval was necessary in order for the Company to continue its development and further construction of mining facilities for the Phoenix Gold Project.

The Company updated certain drilling and operational information relating to the F2 Gold System on December 7, 2011. The details with respect to that updated information are set out in the news release issued by the Company on December 7, 2011 and which is available for review on SEDAR at www.sedar.com.

Results of this updated drilling and operation information included 156.0 g/t gold over 4.0 metres (4.55 oz/ton gold over 13.1 feet) in a shallow southern extension and 90.9 g/t gold over 0.5 metres (2.65 oz/ton gold over 1.6 feet) and 184.7 g/t gold over 0.5 metres (5.39 oz/ton gold over 1.6 feet) in deeper drilling.

With respect to operational information, the Company announced:

· Completion of grid power distribution to underground workings and surface infrastructure, including the new hoisting plant.

· Completion of electrical and mechanical commissioning of new hoist.

· Completion of a head frame extension with new sheave deck and back legs.

· Preparation to resume shaft sinking early in Q1 2012. It is planned to extend the shaft to a depth of 610 metres.

· Continued vertical development of a rock pass from the 305 metre level to the 122 metre level, ongoing lateral development on the 244 metre level and the completion of improved ventilation for underground workings.

· Completion of potable water system.

· Geotechnical drilling on the tailings management facility.

· Ongoing procurement initiatives for SAG and ball mills (long lead items).

· Initiation of studies under the technical services agreement with Agnico-Eagle Mines Limited.

Significant Acquisitions

The Company has not made any significant acquisitions during the financial year ended December 31, 2011 that would require the Company to file a Form 51-102F4 Business Acquisition Report under Part 8 of NI 51-102.

Page 17

Subsequent Events

On February 29, 2012, the Company closed a bought deal equity financing of 49,000,000 common shares of the Company at a price of $4.10 per share for aggregate gross proceeds to the Company of $200,900,000.  An over-allotment option has been granted to the underwriters to purchase up to an additional 15% of the offering, which is exercisable in whole or in part for a period of 30 days from and including the closing date.  To date, no over-allotment has been exercised.

GENERAL DESCRIPTION OF THE BUSINESS

The Company is primarily a mineral exploration company engaged in the acquisition, exploration and development of gold and base-metal exploration properties both through Company-funded and partner-funded exploration.  The Company is also involved in the investment in other mineral exploration and resource companies.  The financial success of the Company is dependent upon its ability to discover economically exploitable mineralization.

The Company controls over 65,000 acres of exploration ground in the Red Lake gold camp, in the province of Ontario.  At present, the Company’s main focus is on advanced exploration and development of its 100% owned Phoenix Gold Property (see “Material Mineral Projects”).  The Company also controls land packages in Alaska and Nevada, United States; however, at present, the Company is not dependent to any material extent on foreign operations. The Company does not have any assets or mineral properties that are in production or that contain a mineral reserve. Please refer to the section of this AIF entitled “Material Mineral Projects” for a description of the Company’s inferred mineral resource estimates.

Specialized Skill and Knowledge

All aspects of the Company’s business require specialized skills and knowledge.  Such skills and knowledge include the areas of geology, engineering, operations, environmental, drilling, logistical planning and implementation of exploration and development programs, treasury, accounting and legal.  While periods of increased activity in the resource mining industry can make it more difficult to locate competent employees and consultants in such fields, the Company has been able to locate and retain such employees and consultants and believes it will continue to be able to do so.

Competitive Conditions

The resource industry is intensely competitive in all of its phases, and the Company competes with many companies possessing greater financial and technical facilities than itself. Competition could adversely affect the Company’s ability to acquire suitable producing properties or prospects for exploration  in the future (see “Risk Factors”).

Page 18

Business Cycles

The mineral exploration business is subject to mineral price cycles. The marketability of minerals and mineral concentrates and the ability to finance the Company on favourable terms is also affected by worldwide economic cycles.

Changes to Contracts

It is not expected that the Company’s business will be affected in the current financial year by the renegotiation or termination of contracts or sub-contracts.

Environmental Protection

The Company conducts exploration activities in the Canadian province of Ontario and the states of Alaska and Nevada in the United States.  Such activities are subject to various laws, rules and regulations governing the protection of the environment, including, in some cases, posting of reclamation bonds.

In Canada, extensive environmental legislation has been enacted by federal and provincial governments. Such legislation imposes rigorous standards on the mining industry to reduce or eliminate the effects of wastes generated by extraction and processing operations and subsequently deposited on the ground or emitted into the air or water.

All phases of the Company’s operations are subject to environmental regulation in the jurisdictions in which it operates. Environmental legislation is evolving in a manner which requires stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed properties and a heightened degree of responsibility for companies and their officers, directors and employees.

If environmental assessments are triggered, they can cause delay to the decision as to whether or not the relevant exploration property will be placed into production. To the best of the Company’s knowledge, all of the Company’s activities are in compliance in all material respects with applicable environmental legislation.

There is no assurance that future changes in environmental regulation, if any, will not adversely affect the Company’s operations. The cost of compliance with changes in governmental regulations has the potential to preclude entirely the economic development of a property.

The financial and operational effects of environmental protection requirements on the Company’s capital expenditures, profit or loss and competitive position have not been significant in the year ended December 31, 2011, and are not expected to become significant until and unless the Company develops a mine on one of its exploration properties.

As at December 31, 2011, the Company has deposited $1,686,224 with the Ministry of Northern Development and Mines (“MNDM”) as financial assurance for future estimated remediation costs associated with the on-going development of the Phoenix Gold Project.  On December 2, 2011, the MNDM accepted and approved the Company’s Production Closure Plan for the Phoenix Gold Project.

Employees

As of the date of this AIF, the Company has 57 full-time employees.  The Company also relies on consultants and contractors to carry out many of its activities and, in particular, to carry out project development activities and to supervise work programs on its mineral properties.

Foreign Operations

The Company is not carrying out work at its foreign operations to any material extent. Although it has exploration properties in Nevada, Utah and Alaska, the Company’s main focus is on exploration of its Phoenix Gold Property in Ontario, Canada.

Bankruptcy, Receivership or Similar Proceedings

There has been no bankruptcy, receivership, or similar proceedings against the Company or any of its subsidiaries, or any voluntary bankruptcy, receivership or similar proceedings by the Company or any of its subsidiaries within the three most recently completed financial years and up to the date of this AIF, and none are proposed for the current financial year.

Material Reorganization

There has been no material reorganization of the Company within the past three financial years or completed during the current financial year and no material reorganization has been proposed for the current financial year.

Social or Environmental Policies

The Company is, and has been, carrying out exploration and development in Canada, principally in the Province of Ontario. Such activities are subject to various laws, rules and regulations governing the protection of the environment, including posting of reclamation bonds.  Management has adopted and is committed to a Health, Safety and Environmental (“HS&E”) Policy designed to ensure that it continues to comply with or exceeds all environmental regulations currently applicable to it.  To the best of the Company’s knowledge, all of the Company’s activities are in compliance in all material respects with applicable environmental legislation.

The HS&E Policy is provided below:

“Health, Safety and Environmental Policy

• “Rubicon Minerals Corporation is committed to eliminating injury and illness in the workplace, and to ensuring the well being of the environment and the communities in areas where the Company operates. To achieve these objectives the Company will:

• Provide staff with the resources to identify, manage and minimize health and safety risks to employees, contractors and communities where the Company operates.

• Assess existing and potential project related risks and avoid, manage or mitigate these risks during all project stages and emergency situations.

Page 20

In addition, Rubicon entered into an Exploration Accommodation Agreement with the Lac Seul First Nation covering certain of Rubicon’s Red Lake area properties that are located on lands considered by the Lac Seul First Nation to be its traditional territory.  See “General Development of the Business - Three Year History - 2010”.

Consistent with its continuing consultation with First Nations whose traditional territory includes Red Lake, Rubicon developed its Aboriginal Policy. The principles of Rubicon’s Aboriginal Policy are provided below:

“Aboriginal Policy

• Rubicon management endeavors to develop and operate sustainable projects that meet high economic, environmental and social standards.

• We respect and value the communities that neighbor our projects, and recognize the unique status of the First Nations and the Métis Nation of Ontario as the original members of those communities.

• Whenever our operations might affect First Nations or the Métis Nation of Ontario, Rubicon seeks to develop enduring relationships with those First Nations and the Métis Nation of Ontario built upon trust and respect.

Rubicon will:

Page 21

• develop and maintain mutually beneficial relationships with First Nations and the Métis Nation of Ontario communities in the areas of our operations.

• initiate and maintain ongoing, transparent and good faith communications with First Nations and the Métis Nation of Ontario in the area of our exploration projects.

• consult with First Nations and the Métis Nation of Ontario communities in the areas of our projects to inform them of our plans and to listen and understand their interests.

• respect the traditional knowledge, cultural practices, and culturally-significant sites of First Nations and the Métis Nation of Ontario.”

RISK FACTORS

An investment in the common shares of the Company is highly speculative and subject to a number of risks. An investor should carefully consider the risk factors described below, together with all of the other information included or incorporated by reference in this AIF.

The risks described below are not the only ones which may affect the Company. Additional risks that the Company currently does not foresee or believes to be immaterial may become important factors that affect the Company’s business. If any of the following risks occur, or if others occur, the Company’s business, operating results and financial condition could be materially adversely affected and investors may lose all of their investment.  Details of the risk factors identified under this heading and “Forward-Looking Statements” in this AIF should be carefully reviewed and evaluated by prospective investors before purchasing the common shares of the Company.

The Company is subject to a number of risks due to the nature of its business and the present stage of development of business. The following factors should be considered:

Resource Exploration and Development is Generally a Speculative Business

Resource exploration and development is a speculative business and involves a high degree of risk, including, among other things, unprofitable efforts resulting both from the failure to discover mineral deposits and from finding mineral deposits which, though present, are insufficient in size and grade at the then prevailing market conditions to return a profit from production.  The marketability of natural resources which may be acquired or discovered by the Company will be affected by numerous factors beyond the control of the Company.  These factors include market fluctuations, the proximity and capacity of natural resource markets, government regulations, including regulations relating to prices, taxes, royalties, land use, importing and exporting of minerals and environmental protection.  The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in the Company not receiving an adequate return on invested capital.

Page 22

The Company has no mineral producing properties at this time.  Only those mineral deposits that the Company can economically and legally extract or produce, based on a comprehensive evaluation of cost, grade, recovery and other factors, are considered “mineral reserves”.  The Company has not defined or delineated any proven or probable mineral reserves on any of its properties.  Although the resource estimates contained in the Technical Report (incorporated by reference herein) have been prepared by Qualified Persons, these amounts are inferred and indicated resource estimates only and no assurance can be given that any particular level of recovery of gold, silver or other minerals from mineralized material will in fact be realized or that an identified mineralized deposit will ever qualify as a commercially mineable (or viable) reserve.  See “Forward-Looking Statements”, “Caution Regarding Reference to Resources and Reserves”, “General Development of the Business” and “Material Mineral Projects” in this AIF.

Extensive development of any of the Company’s properties will only follow upon obtaining satisfactory exploration results and successful economic studies.  Mineral exploration and development involve a high degree of risk and few properties which are explored are ultimately developed into producing mines. There is no assurance that the Company’s mineral exploration activities will result in the discovery of a body of commercial ore on any of its properties.  Several years may pass between the discovery of a deposit and its exploitation.  Most exploration projects do not result in the discovery of commercially mineable mineralized deposits.

Mineral Resource Estimates

The mineral resource figures referred to in the Technical Report, this AIF and the documents incorporated herein by reference, and in documents filed by the Company from time to time on SEDAR at www.sedar.com are estimates only and no assurance can be given that any particular level of recovery of gold or other minerals from mineral resources will in fact be realized or that an identified mineral deposit will ever qualify as a commercially mineable (or viable) ore body which can be economically exploited.  There can be no certainty that any mineral resources will be converted to mineral reserves.  Mineral resources which are not mineral reserves do not have demonstrated economic viability.

Any material change in the quantity of mineralization, grade or ore to waste ratio, or the price of gold may affect the economic viability of any property held by the Company.  In addition, there can be no assurance that gold recoveries or other metal recoveries in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.

The grade of the reported mineral resource estimates is uncertain and it is uncertain whether further technical studies will result in an upgrade to it.  Further drifting on the mineralized zones is required to complement the current bulk sample and add confidence in the continuity of mineralized zones in comparison to the current block model.

Until mineral reserves and resources are actually mined and processed, the quantity of mineral reserve and resource grades must be considered as estimates only.

Title Risks

The confirmation of title to resource properties is a very detailed and time-consuming process.  Title to, and the area of, the mineral interests held by the Company may be disputed.  There is no guarantee that such title will not be challenged or impaired.  There may be challenges to the title of the properties in which the Company may have an interest, which, if successful, could result in the loss or reduction of the Company’s interest in the properties.

Page 23

Although title to its material property has been reviewed by independent counsel and an opinion of title has been obtained by or on behalf of the Company, no assurances can be given that there are no title defects affecting the properties.  Title insurance generally is not available for mining claims and other types of mineral tenure in Canada and the Company’s ability to ensure that it has obtained secure title to individual mineral properties may be severely constrained.

Although a legal boundary survey exists on its Phoenix Gold Property, Rubicon has not conducted surveys of all of its other mineral interests in which it holds direct or indirect interests; therefore, the precise area and location of such claims may be in doubt.  Accordingly, properties may be subject to prior unregistered liens, agreements, transfers or claims, and title may be affected by, among other things, undetected defects.  In addition, Rubicon may be unable to conduct work on the properties as permitted or to enforce its rights with respect to its properties.

Aboriginal Title and Rights Claims

Aboriginal title and rights may be claimed with respect to Crown properties or other types of tenure with respect to which mining rights have been conferred.  The Company is not aware of any treaty land entitlement claims or Aboriginal land claims having been formally asserted or any legal actions relating to Aboriginal issues having been instituted with respect to the Phoenix Gold Property.  There can be no assurance that treaty or Aboriginal rights will not be asserted in the future in respect of the Phoenix Gold Property, or any of the Company’s other properties.  In addition, other parties may dispute the Company’s title to its properties and its properties may be subject to prior unregistered agreements or transfers or land claims by Aboriginal peoples, and title may be affected by undetected encumbrances or defects or government actions.

Uncertainty of Acquiring Necessary Permits and Licenses

Although the Company’s Production Closure Plan was approved by the MNDM on December 2, 2011, and the remaining permits required for the projected production phase (as contemplated in the PEA) of the Phoenix Gold Project were received in Q1 of 2012, the operations of the Company will still require certain non-material approvals from various governmental authorities as the development continues.  There can be no assurance that the Company will be able to obtain all necessary currently unanticipated licenses and permits that may be required to carry out exploration, development and mining operations at its projects, on reasonable terms or at all. Delays or failure to obtain such licenses and permits, or failure to comply with the terms of any such licenses and permits that the Company does obtain, could have a material adverse effect on the Company.

Governmental Regulation

Exploration activities on the Company’s properties are affected to varying degrees by: (i) government regulations relating to such matters as environmental protection, health, safety and labour; (ii) mining law reform; (iii) restrictions on production, price controls, and tax increases; (iv) maintenance of claims; (v) tenure; and (vi) expropriation of property.  There is no assurance that future changes in such regulation, if any, will not adversely affect the Company’s operations.  Changes in such regulation could result in additional expenses and capital expenditures, availability of capital, competition, reserve uncertainty, potential conflicts of interest, title risks, dilution, and restrictions and delays in operations, the extent of which cannot be predicted.

Page 24

Exploration on the Company’s properties requires responsible best exploration practices to comply with Company policy, government regulations, maintenance of claims and tenure.  The Company is required to be registered to do business and have a valid prospecting license (required to prospect or explore for minerals on Crown Mineral Land or to stake a claim) in any Canadian province or U.S. State in which it is carrying out work.  Mineral exploration primarily falls under provincial jurisdiction in Canada.  However, the Company is also required to follow the regulations pertaining to the mineral exploration industry that fall under federal jurisdiction, such as the Fisheries Act (Canada).

If any of the Company’s projects are advanced to the production stage, those operations will also be subject to various laws and regulations concerning production, taxes, labour standards, environmental protection, mine safety and other matters.

Market Price of Company’s Shares and Financing

Since the Fall of 2008, worldwide securities markets, particularly those in the United States and Canada, have experienced an increased level of price and volume volatility, and the market price of securities of many companies have not necessarily been related to the operating performance, underlying asset values or prospects of such companies.  As a result, the market price of the securities of the Company at any given time may not accurately reflect the long term value of the Company.  In particular, the price of the Common Shares fluctuated from a high of $6.00 to a low of $3.05 per share during the financial year ended December 31, 2011.  There can be no assurance that fluctuations in the price of the Common Shares will not continue to occur, or that such fluctuations will not materially adversely impact the Company’s ability to raise equity funding without significant dilution to its existing shareholders.  See “Market for Securities: Trading Price and Volume”.

Competition

The resource industry is intensively competitive in all of its phases, and the Company competes with many companies possessing greater financial resources and technical facilities.  As such, the Company must maintain and enhance its high technical abilities in order to compete in raising capital and delivering exploration results.  Competition could adversely affect the Company’s ability to acquire suitable producing properties or prospects for exploration in the future.

Operating Hazards and Risks

Mineral exploration involves many risks. The operations in which the Company has a direct or indirect interest will be subject to all the hazards and risks normally incidental to surface and underground exploration, any of which could result in work stoppages and damage to persons or property or the environment and possible legal liability for any and all damage.  Fires, power outages, labour disruptions, flooding, unexpected ground conditions and the inability to obtain suitable or adequate machinery, equipment or labour are some of the risks involved in the conduct of exploration programs.

Risks involved in mining operations include unusual and unexpected geologic formations, seismic activity, cave-ins, flooding and other conditions involved in the drilling and removal of any material, any of which could result in damage to life or property, environmental damage and possible legal liability.  Further, weather conditions over a prolonged period can adversely affect exploration, production, mining and drilling operations and the timing of earning revenues.

Page 25

Infrastructure

Mining, processing, development and exploration activities depend on adequate infrastructure.  Reliable roads, bridges, power sources and water supply are important determinants, which affect capital and operating costs.  The Company will need sufficient infrastructure to commence and continue mining operations at the Phoenix Gold Property.  Unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of such infrastructure could also adversely affect the Company’s operations, financial condition and results of operations.

Environmental Quality Requirements

Province of Ontario

Legislation and regulations implemented by the MNDM and the Ministry of Natural Resources (“MNR”) directly affect the mining industry in the province of Ontario where the Company holds its material mineral claims.  The Company can carry out exploration work including drilling, trenching, heavy mineral studies, airborne geophysical surveys, extensive use of off road vehicles, establishment of a camp or other activities capable of causing ground disturbance, water quality impairments or disruption to wildlife or wildlife habitat, provided that it complies with applicable provincial and federal acts and regulations in so doing.

The Acts and Regulations which guide exploration activity in Ontario include the Mining Act, Public Lands Act, Forest Fires Prevention Act, Lakes and Rivers Improvement Act, Crown Forest Sustainability Act, Fish and Wildlife Conservation Act, Occupational Health and Safety Act, Health Protection and Promotion Act, Environmental Protection Act, Ontario Water Resources Act and the regulations to the Gasoline Handling Act.  The Company remains current with evolving legislation, including the modernization of Ontario’s Mining Act and the regulation thereunder to maintain regulatory compliance.

United States

Federal initiatives are often administered and enforced through state agencies operating under parallel state statutes and regulations. Although some mines continue to be approved in the United States, the process is increasingly cumbersome, time-consuming, and expensive, and the cost and uncertainty associated with the permitting process could have a material effect on exploring, and mining the Company’s properties.  Compliance with statutory environmental quality requirements described above may require significant capital investments, that significantly affect the Company’s earning power, or cause material changes in the Company’s intended activities.  Environmental standards imposed by federal, state, or local governments may be changed or become more stringent in the future, which could materially and adversely affect the Company’s proposed activities.  As a result of these matters, the Company’s U.S. operations could be suspended or cease entirely.

In the United States, federal laws and regulations adopted and administered by the U.S. Environmental Protection Agency, Forest Service, Bureau of Land Management, Fish and Wildlife Service, Mine Safety and Health Administration, and other federal and state agencies, and laws and regulations such as the Federal Clean Water Act, Clean Air Act, Comprehensive Environmental Response, Compensation, and Liability Act, Resource Conservation and

Page 26

Recovery Act, Safe Drinking Water Act, Endangered Species Act, Migratory Bird Treaty Act, Bald and Golden Eagle Protection Act, National Environmental Policy Act, National Historic Preservation Act, Native American Graves Protection and Repatriation Act, Archaeological Resources Protection Act, and Paleontological Resources Preservation Act, and their state counterparts and similar statutes, have a direct bearing on U.S. exploration and mining operations.  Numerous federal and state governmental authorities, have the power to enforce compliance with these laws and regulations and the permits issued under them, and their interpretation and enforcement of these laws, regulations and permits have tended to become more stringent over time.  Failure to comply with these laws, regulations and permits may result in the assessment of administrative, civil or criminal penalties; the imposition of investigatory, remedial or monitoring obligations; and the issuance of injunctions limiting or prohibiting some or all of our operations. These laws and regulations will make the process for preparing and obtaining approval of a plan of operations much more time-consuming, expensive, and uncertain.  Plans of operation will be required to include detailed baseline environmental information and address how detailed reclamation performance standards will be met.  In addition, all activities for which plans of operation are required will be subject to a standard of review by the Bureau of Land Management, which must make a finding that the conditions, practices or activities do not cause substantial irreparable harm to significant scientific, cultural, or environmental resource values that cannot be effectively mitigated.

The Company is able to conduct its exploration within the provisions of the applicable environmental laws and regulations without undue constraint on its ability to carry on efficient operations.  The estimated annual cost of environmental compliance for all properties held by the Company in the exploration stage is minimal and pertains primarily to carrying out diamond drilling, trenching or stripping.  Environmental hazards may exist on the Company’s properties, which hazards are unknown to the Company at present, which have been caused by previous or existing owners or operators of the properties.

Management

The Company is dependent upon a number of key officers, employees and directors:  David W. Adamson, President and Chief Executive Officer; William J. Cavalluzzo, Vice-President, Investor Relations; Glenn Kumoi, Vice-President General Counsel and Corporate Secretary, Matthew Wunder, Vice-President Exploration, Claude Bouchard, Vice-President Operations and Robert Lewis, Chief Financial Officer.  The loss of any one or more of the named officers and employees could have an adverse effect on the Company.  The Company has entered into management contracts with Messrs. Adamson, Cavalluzzo, Bouchard, Kumoi, Wunder and Lewis.  See “Directors and Officers”.  The Company does not maintain key person insurance on any of its management members.

Conflict of Interest

Certain directors of the Company are directors of, or may become associated with, other natural resource companies that acquire interests in mineral properties.  Such associations may give rise to conflicts of interest from time to time. Such conflicts pose the risk that the Company may enter into a transaction on terms which place the Company in a worse position than if no conflict existed.  The officers and directors of the Company are required by law to act honestly and in good faith with a view to the best interests of the Company and its shareholders and to disclose any interest which they may have in any project or opportunity of the Company, but each officer or director has the identical obligation to other companies for which such officer or director serves as an officer or director.

Page 27

Limited Operating History:  Losses

The Company has no mineral properties in production and has no revenues from operations.  The Company has experienced, on a consolidated basis, losses of $21,396,497 and $25,510,721 in the years ended December 31, 2011 and 2010, respectively.  The Company does not anticipate it will earn any material revenue in 2012 and anticipates it will incur losses for the foreseeable future.  There can be no assurance that the Company will operate profitably in the future, if at all.  As at December 31, 2011, the Company’s deficit was $74,522,449.

Shares Reserved for Future Issuance:  Dilution

As at December 31, 2011, there were 9,895,996 options outstanding at a weighted average price of $3.84 per share and no warrants outstanding.  The exercise of these options will result in further dilution to the Company’s shareholders and pose a dilutive risk to potential investors.

Occupier Liability and Environmental Hazard Risks

On the Phoenix Gold Property, there are a number of mine structures (hoist, head frame) and mine features (unused tailings and settling ponds, rock dumps and processing plant) which were used by the previous owners to gain underground access and stockpile mill feed.  The mill was never fully commissioned and only 2,500 tons of mill feed were processed.  The Company conducts on-going activities in accordance with government legislation to ensure the site is safe and secure. The rehabilitation of the site was reviewed under a Closure Plan for the development and production phase, which was approved by the MNDM in December 2011. See also “Governmental Regulation” above.

Insurance and Uninsurable Risks

Exploration, development and production operations on mineral properties involve numerous risks, including unexpected or unusual geological operating conditions, rock bursts, cave-ins, ground or slope failures, fires, floods, earthquakes, cyclones and other environmental occurrences, as well as political and social instability that could result in damage to or destruction of mineral properties or producing facilities, personal injury or death, environmental damage, delays in mining caused by industrial accidents or labour disputes or changes in regulatory environment, monetary losses and possible legal liability.  It is not always possible to obtain insurance against all such risks and the Company may decide not to insure against certain risks because of high premiums or other reasons.  Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to the Company or to other companies in the mining industry on acceptable terms.  Although the Company maintains insurance to protect against certain risks in such amounts as it considers reasonable, its insurance will not cover all potential risks associated with its operations, and insurance coverage may not continue to be available or may not be adequate to cover any resulting liability.  Should such liabilities arise, they could reduce or eliminate any further profitability and result in increasing costs and a decline in the value of the securities of the Company.

Page 28

Accounting Policies and Internal Controls

Commencing January 1, 2011, the Company prepared its financial reports in accordance with International Financial Reporting Standards.  In preparation of financial reports, management may need to rely upon assumptions, make estimates or use their best judgment in determining the financial condition of the Company.  Significant accounting policies are described in more detail in the Company’s audited financial statements.  In order to have a reasonable level of assurance that financial transactions are properly authorized, assets are safeguarded against unauthorized or improper use, and transactions are properly recorded and reported, the Company has implemented and continues to analyze its internal control systems for financial reporting.  Although the Company believes its financial reporting and financial statements are prepared with reasonable safeguards to ensure reliability, the Company cannot provide absolute assurance.

Future Litigation may Impact the Company

While the Company does not currently have any claims against it, the Company may, in the future, be subject to claims (including class action claims and claims from government regulatory bodies) based on allegations of negligence, breach of statutory duty, public nuisance or private nuisance or otherwise in connection with its operations or investigations relating thereto. While the Company is presently unable to quantify its potential liability under any of the above heads of damage, such liability may be material to the Company and may materially adversely affect its ability to continue operations.  The Company maintains liability insurance to cover certain portions of these potential claims.

Dividends

The Company has no history of earnings and as such the Company has not paid dividends on its Common Shares since incorporation and does not anticipate doing so in the foreseeable future.  Payment of any future dividends will be at the discretion of the board of directors after taking into account many factors, including operating results, financial condition and anticipated cash needs.

“Introduction

This Technical Report on the F2 Gold System, Phoenix Gold Project (the Project) within the larger Phoenix Gold Property (the Property) in Bateman Township, Red Lake, Canada has been prepared by AMC Mining Consultants (Canada) Ltd (AMC) of Vancouver, Canada on behalf of Rubicon Minerals Corporation (Rubicon) of Vancouver, Canada. It has been prepared in accordance with the requirements of National Instrument 43-101 (NI 43-101), “Standards of Disclosure for Mineral Projects”, of the Canadian Securities Administrators (CSA) for lodgement on CSA’s “System for Electronic Document Analysis and Retrieval” (SEDAR). This report is the disclosure of a Preliminary Economic Assessment (PEA) carried out by AMC. It is [also an] update to the mineral resources stated in a previously published Technical Report entitled “Technical Report, Mineral Resource and Geological Potential Estimates, F2 Gold System - Phoenix Gold Project”, prepared for Rubicon by GeoEx Limited, and effective 11 April 2011.

This PEA is preliminary in nature, includes Inferred Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.

History, Location and Ownership

The Property was initially staked by McCallum Red Lake Mines Ltd in 1922. Ownership changed several times until Rubicon optioned the Property from Dominion Goldfields Corporation (DGC) (Water Claims) and 1519369 Ontario Ltd (Land Claims) in 2002.

Page 30

It is located in the southwestern part of Bateman Township within the Red Lake Mining Division of northwestern Ontario, at the northern end of the McFinley Peninsula and partly under the East Bay of Red Lake. The site incorporates the former McFinley underground mine, a shaft and hoist system, and other surface infrastructure. The town of Red Lake is approximately 265 km NE of Winnipeg and is serviced by road and air, with daily scheduled flights from Winnipeg and Thunder Bay. The closest railway is approximately 160 km south. Temperatures range from summer highs of 35°C to winter lows of -40°C. Weather conditions allow drilling from the ice of Red Lake during January to early April.

The Property consists of 38 contiguous blocks covering 509.4 ha that are comprised of 16 patented mining claims (Land Portion), one unpatented staked claim, one mining lease and 25 licenses of occupation (Water Portion). The Water Portion claims are subject to a 2% Net Smelter Return (NSR) royalty with a requirement to pay advance royalties and an option to acquire a 0.5% NSR royalty for US$675,000. The Land Portion claims are subject to a sliding scale, 2-3% NSR royalty depending on the price of gold, with a requirement to pay advance royalties and an option to acquire a 0.5% NSR royalty for $1,000,000.

Rubicon holds all permits required to allow it to carry out its current drilling and underground exploration program and is in the process of acquiring additional permits required in contemplation of future production.

Geology and Mineralization

The Red Lake Greenstone Belt is located in the western portion of the Canadian Shield, and consists of an EW trending sequence of volcanic and sedimentary rocks with volcanic intrusives that span a period of 300 million years.

The local area is underlain by three sequences of primarily tholeiitic mafic volcanic rocks, separated by marker horizons of felsic and ultramafic volcanic rocks. A strong NNE trending structural fabric through the area is considered part of the East Bay Deformation Zone (EBDZ), which dominates the geology of the area.

The F2 Gold System comprises a NE-trending, steeply W-dipping sequence with numerous lode gold shoots typical of the Red Lake Camp containing high grade gold mineralization, hosted within ‘Hi-Ti’ Basalt and Felsic Intrusive lithologies within a larger body of ultramafic and mafic talc-rich lithologies. The geological sequence is reasonably consistent along the length of the Property for over 4 km. Rock types hosting mineralization have been correlated over vertical distances of approximately 1,500m and horizontal distances of approximately 1,200 m.

Delineation drilling of the F2 Core Zone has defined the presence of NNE-trending gold mineralization associated with silicification, quartz veining and strong alteration within, and adjacent to, favourable host rock types. Gold mineralization also occurs in NW-trending structures that are generally confined within, or immediately adjacent to, NE-trending bounding geological units and parallel to the regional F2 fold trend direction. Typically, this mineralization occurs as local quartz veining and brecciation.

Exploration

Rubicon has conducted extensive exploration programs since acquiring the property. Work has included geological mapping, re-logging of selected historic drillholes, digital compilation of all historical data available, high resolution airborne magnetic survey, ground magnetic survey, seismic lake bottom topographic survey, Titan 24 geophysical survey and numerous drilling programs, all of which have been covered in this or the earlier Technical Reports.

Page 31

Since 2002, Rubicon has completed 313,030 m of diamond drilling (182,802 m surface drilling and 130,228 m underground drilling) to February 28, 2011. In the fourth quarter of 2010, a 27,000 m underground drilling program was initiated, designed to test a 150 m (horizontal) by 200 m (vertical) area within the F2 Core Zone. This program identified discrete sub-zones within the F2 Core Zone and returned some high-grade gold intercepts. The total system has now been expanded to a strike length of approximately 1,240 m and to depths of around 1,460 m vertically.

AMC’s mineral resource estimate is based on approximately 259,000 m of drilling completed on the F2 Gold system between 2008 and 28 February 2011.

Data Quality and Management

Collar surveying of proposed and completed drillholes, and down-hole surveying of holes, has been undertaken to good industry standards. Core recovery has generally been excellent.  [Rock Quality Data (“RQD”)] measurements are completed on the core, as well as representative specific gravity and magnetic susceptibility measurements.

Core handling, splitting and sampling procedures are standard and the facilities are good with 24 hour on-site security including personnel and video surveillance. All analytical or testing laboratories used by Rubicon are independent. While a number of analytical laboratories have been used over time, assaying since January 2008 has been conducted by SGS in Red Lake.

Blank and standards assay protocols were developed in 2003 and revisited in 2009 with input from Dr. B. Smee, Ph.D., P.Geo, Independent Geochemist. Since May 2010, ioGlobal Pty Ltd has taken over the management of the project assay data, providing independent quality control and quality assurance reporting and database auditing.

AMC is satisfied that the sample preparation, security, analytical procedures and application of Quality Assurance/Quality Control (QA/QC) analysis is performed in accordance with industry good practice and that the database is appropriate for resource modelling and estimation.

Mineral Resources and Mineral Reserves

AMC has estimated mineral resources using a block modelling approach based on all drilling up to 28 February 2011. The estimate is not constrained vertically by a potential crown pillar and extends to incorporate all data at depth. Summary results at a cut off grade of 5.0 g/t Au are shown in Table 1 below.

Page 32

Table 1                      Summary of Mineral Resource Estimates as of 15 June 2011

Classification	M Tonnes	g/t Au	M oz Au
Indicated	1.028	14.5	0.477
Inferred	4.230	17.0	2.317

Notes: 1. CIM definitions used for mineral resources

2. Cut off grade applied 5.0 g/t Au

3. Capping value of 270g/t Au applied to composites

4. Based on drilling results to 28 February, 2011

A total of 511 drillholes were used in the modelling. Rubicon’s interpretations of lithologies, mineralization controls and geology domains were reviewed and accepted by AMC. Mineralized domains (total of 12) were interpreted by AMC using a low gold threshold (0.1 g/t Au), and were further expanded to incorporate all significant mineralized zones.

A composite length of 1.0 m was chosen and grades were capped at 270 g/t Au after compositing. The parent block size was 2 m by 8 m by 12 m, with sub blocking utilized. Search parameters were 8 m by 24 m by 36 m for the first pass, two times these parameters for the second pass and three times these parameters for the third pass. The search ellipse was orientated to take cognizance of the predominant orientation of the mineralization as known. Grade interpolation was by inverse distance cubed. An average bulk density value of 2.90 t/m3 was used for all rock types. Resource classification was carried out using data support as a main criteria with a manual review creating volumes based on drillhole density and number of samples to inform a block.

There are currently no mineral reserves quoted for the Project.

Underground Activities and Potential Mining

Rubicon has rehabilitated parts of the existing McFinley Mine workings, including the shaft, which it has deepened to just below 305 Level (305L). It has undertaken lateral and raise development to enable the establishment of diamond drilling stations on 122L, 244L and 305L, and has recently begun construction of a new hoist and headframe with the capability to exceed the envisaged, steady-state hoisting rate of 1,250 tonnes per day (tpd).

In AMC’s view, economic mineralization in the F2 Zone is likely to be relatively discontinuous, (as typical for lode gold style mineralization), requiring a flexible mining approach and a high and sustained geological effort, including closely spaced definition drilling, to facilitate understanding localized mineralization trends

The selected primary mining method is conventional, captive cut and fill, with paste fill using mill tailings. Mining widths will be typically around 2 m, ranging from 1.5 m or less to 3 m or more. Ore will be mined using stopers, jacklegs, slushers and mucking machines, dumped to an ore pass, loaded into track cars, passed to a shaft loading pocket via a grizzly and then hoisted to surface. Waste development will also generally be done using stopers, jacklegs and mucking machines.

Page 33

Cross-cut and access development from the shaft at nominal 2.4 m width by 2.7 m height is envisaged on levels at 61 m intervals between 183L and 1403L, complementary to the present 305L development. Necessary raising for waste, fresh-air and mine egress will be undertaken together with development of loading pockets for waste adjacent to the shaft. Ore passes at 2.4 m by 2.4 m will be developed at points central to the stoping areas. The required lateral and raising development is projected to continue over the first twelve years of the project.

The shaft bottom is currently at around 30 m below 305L, with eventual deepening of the shaft projected to just below 1464L. For the projected initial mining stage and prior to completion of shaft sinking, ore immediately below 305L may be accessed via ramp development.

AMC has undertaken regular geotechnical inspections and audits over a two year period and has developed provisional ground support standards for ongoing site activities in conjunction with Rubicon. AMC’s geotechnical investigations have included a recommendation that a minimum crown pillar thickness of 45 m be maintained for the typical mining widths envisaged.

Groundwater flows appear unlikely to be a material issue for underground mining, but AMC has included a hydrological assessment in its recommendations. A third-party ventilation report has been reviewed by AMC, and the system proposed is considered appropriate for the mining methodology, equipment and production rates envisaged. Additional ventilation capability would be required if significant development were to occur using diesel scoops.

As the Project is at a PEA level, no mineral reserves have been estimated. To assess the preliminary economics of the Project, AMC has applied a cut-off grade of 6.0 g/t Au to the resource estimate lying between 1464L and the base of the planned crown pillar (approximately at 122L), based on an initial operating cost estimate of $200 /tonne and a gold price of US$1,040 /oz. Final cost estimation and use of a gold price of $1,100/oz for the PEA has confirmed that a mining cut-off grade of 6.0 g/t Au is reasonable at this stage of the Project. Mining dilution and recovery have been considered as have the possibly anomalously high grades of the deepest resource blocks, which are relatively poorly supported in terms of drillhole data.

Production is currently planned to start at 750 tpd, increase to around 970 tpd in the fourth year and reach a steady-state level of 1,250 tpd in the fifth year. A 14-year project life is envisaged for the resources scheduled in the PEA, with the first two years being devoted to key surface and underground infrastructure construction, including mill and paste plant, shaft sinking, lateral and raise development, etc. Total mine production over the 12-year life of mine is projected at 4.5 Mt, for total gold mined of around 2M ounces.

In early 2011, Rubicon extracted two 1,000 t bulk samples representing two underground areas on the 305L. Metallurgical testwork was conducted on the samples under the supervision of a processing consultant. Weighted average grades from drilling of the broad zones from within which the bulk samples were extracted are compared with metallurgical test results in Table 2.

Page 34

Table 2                      Comparison of Bulk Sampling to Drill Data

Item	WLB2 grade - g/t Au	F2 Core grade - g/t Au
Delineation Drilling Weighted Average	5.8	9.1
Milled Bulk Sample Testing Results	7.1	8.2

Processing

Proposed metallurgical processing consists of a single line, starting with a semi-autogenous grinding (SAG) mill. The discharge from the SAG mill is pumped to hydrocyclones for classification. A gravity separation circuit is included in closed circuit with hydrocyclones to recover any gravity recoverable gold prior to regrinding in a ball mill. Gold is extracted in a conventional carbon-in-leach (CIL) circuit. The loaded carbon is washed with hydrochloric acid solution to remove carbonate. Gold is then removed from the loaded carbon by stripping (elution) followed by electrowinning and smelting of doré in an electric induction furnace. The stripped carbon is regenerated in a reactivation kiln before being reintroduced to the process. Fine carbon is constantly eliminated from the process to avoid gold loss, with fresh carbon being continuously added to the process.

The cyanide in the tailings from the CIL circuit is removed in a cyanide destruction tank with SO2 and air diffuser placed at the bottom of the tank. Once the cyanide is destroyed, the tailings pass through the paste plant to produce a paste product. The paste produced can be sent to the tailings management facility (TMF) or used in the mine for backfill after the addition of cement and/or other binder to meet fill strength requirements.

Gold feed tonnage is projected to be 450,000 tonnes per annum (tpa) at steady state (Project years 05 through 11). Gold recovery is projected at 92.5%, with an average of 180,000 ounces of saleable gold per annum resulting over the steady state period. The mining scenario average head grade of 13.9 g/t gives 1.86 M saleable ounces of gold over the LOM.

Services and Infrastructure

Electrical power at the Project site is currently supplied by diesel generators. Rubicon has accepted an Offer to Connect from Hydro One for 5.3MW of electricity from the 44KV grid in the Municipality of Red Lake, via a 10.4 km power line. It has constructed a connection to the grid and is securing title to the required right-of-way. A fibre-optic line will be installed along the same route as the power-line to provide communication capability for the site.

Compressed air is currently supplied to underground via a surface compressor set-up that AMC believes will be adequate for the underground mining activity envisaged. Mine water is pumped to a holding tank at the site from the nearby East Bay of Red Lake. Use of paste fill means that there should be no significant source of waste water in the mine other than groundwater.

Process water will be a combination of water from East Bay, clarified water recycled from the TMF, water from the plant site sump and treated water from the mine and mill.

Page 35

A TMF was constructed at the Project site in 1988 in preparation for a bulk-sampling program. The termination of activities in 1989 resulted in minimal use of this area. The TMF, and other sewage works, have been re-activated and approved under various Ontario government regulations. The TMF and effluent treatment plant have been designed to withstand a 30 day duration, 1 in 100 year rain or snow event.

There are no waste rock piles at the Project site related to historic development activities. Waste rock from future development activities will be consumed by roadbed, used to fill stopes or stored in the TMF. Mineralized material will be temporarily stockpiled on surface before processing. There will be no significant stockpiles of mineralized material at closure.

Environmental and Social

Rubicon has been advancing environmental and social aspects of the Project, including baseline monitoring and closure plans, since 2007. All are progressing satisfactorily with necessary permits being obtained or in progress and, to date, there have been no issues identified that post a material risk to project development and envisaged production.

Any waste rock not used for project purposes will be stored in the TMF, which will be monitored during project operation and rehabilitated at the end of mine life. Tests on representative samples suggest that tailings may ultimately turn acidic. A supplemental characterization program is continuing and will determine the need to implement a management plan to address potential chemical stability concerns. At closure, the TMF and plant sites will be covered with an engineered, low-permeability dry cover that will minimize infiltration of water.

Previous environmental work identified soil metal concentrations in parts of the 1980s brownfield project site that were above regulatory criteria. A risk assessment concluded that there was no unacceptable risk to the environment or to human health provided the project site is managed in accordance with applicable government legislation.

Surveys to date have not identified any endangered plants, animals or aquatic life that would be adversely affected by project development. Further field studies are being or will be conducted to ensure adherence to relevant government regulations.

There are no concerns with respect to instability at surface due to the underground workings that were developed in the 1980s. AMC has evaluated crown pillar requirements in accordance with government regulations and made recommendations for crown pillar dimensions to prevent instability at surface.

Environmental liabilities associated with the Project site are described in the February 2009 Phoenix Advanced Exploration Project Closure Plan, filed with the provincial government. In summary, there are no material chemical or physical stability liabilities associated with the historical development or the advanced exploration phase of the Project. Rubicon intends to identify and manage any liabilities associated with the production phase of the Project in order to mitigate potential impacts[.] Financial assurance has been provided to the Government of Ontario to rehabilitate all identified features of the Project site.

Page 36

A Form 1 Notice of Project Status was submitted in Q1 2011 to move the Project from advanced exploration to production status. The submission of this Notice did not give indication of commencement of commercial production. Approvals that relate to the advanced exploration phase of the project generally apply to the production phase.

Postings on the provincial Environmental Registry for various permits have not resulted in negative comments or requests for an individual environmental assessment. The Canadian Environmental Assessment Agency has confirmed that the production phase of the Project will not trigger an Environmental Assessment (EA) pursuant to the Canadian Environmental Assessment Act. A Class EA that was required, pursuant to Ontario Regulation 116/01 was completed and circulated for public comment in March 2011. No comments were received and the Class EA process was completed in April 2011.

Annual public information sessions were held in the Red Lake community in December 2008, 2009 and 2010. No negative comments have been received during the public information sessions to date. Rubicon has undertaken consultation with aboriginal communities and commissioned an independent traditional use study. This study concluded that the project site is within the traditional territory of Lac Seul First Nation and Wabauskang First Nation. Rubicon has consulted with these groups since 2007 / 2008.

An archaeological study of the McFinley Peninsula commissioned by Rubicon did not identify any sites with a high potential to host a cultural heritage value within the development footprint. Also, as the project involves the re-development of the existing footprint with only moderate expansion, the potential for impacts to cultural heritage values is considered to be negligible.

Rubicon has developed a Project Closure Plan to guide the closure of the project in accordance with industry best practices. Close-out rehabilitation activities will be completed within approximately 36 months of project closure.

90% of the envisaged pre-production capital is shared between two areas, surface infrastructure including the mill (59%), and underground infrastructure including underground development (31%). The major component (75%) of the surface infrastructure cost is the mill, which includes construction of a paste fill plant. Excavation items account for 76% of the underground infrastructure.

Sustaining capital is estimated to total approximately $52 M over the life of the Project. The major component (75%) is related to underground infrastructure development.

An average total operating cost of $214 /t has been estimated. The estimated average operating cost per recovered Au ounce is $519. A category breakdown of operating costs is shown in Table 3.

Page 38

Table 3  Operating Costs

Total mining cost averages about $150 /t, with the labour portion (including contractors) at around $95 /t reflecting the manpower-intensive nature of captive cut and fill mining. It is assumed that contractor labour will be used for all raising, including raiseboring, and that Rubicon personnel will be responsible for capital and operating development and stoping.

Economic Analysis

It should be noted that this PEA is preliminary in nature, includes Inferred Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.

AMC has assessed the pre-royalty and pre-tax economics of the project using base case parameters of: gold price - $US1,100 /oz; exchange rate - $CAN1 = $US1; discount rate - 5%; gold recovery from mined ounces - 92.5%. Table 4 summarizes production, cost, revenues and economics for the base parameters.

Page 39

Table 4 Production, Cost, Revenues and Economics for Base Case Parameters

As per Figure 1, Project NPV has the following sensitivities to variation in key parameters (all other factors remaining constant):

· NPV5% ranges from $345M to $520M with +/- 30% variation in capital cost

· NPV5% ranges from $237M to $628M with +/- 30% variation in operating cost

· NPV5% ranges from $650M to $216M with +/- 30% variation in production

· NPV5% ranges from $845M to $20M with +/- 30% variation in Au price, grade or exchange rate

Page 40

Figure 1 NPV Sensitivity

The Project is therefore most sensitive to variations in gold price, grade and exchange rate.

Conclusions

The PEA indicates that the Phoenix Project has significant potential to become an economically viable mining operation.

The resource modelling used as the basis for the PEA employed a cut off grade of 5.0 g/t and has resulted in estimates of 1.03 Mt at 14.5 g/t of Indicated Resources (477,000 ounces Au) and 4.23 Mt at 17.0 g/t Au of Inferred Resources (2,317,000 ounces Au) for the F2 Zone lode-style mineralization.

The scenario for a potential mining operation envisages a two-year pre-production period with a 12-year Life of Mine (LOM) using a captive cut and fill method with up to six horizons being mined simultaneously. Around 450,000 tonnes would be produced annually at steady state. Average mined grade over the LOM is projected at 13.9 g/t.

Pre-production capital expenditures of $214 M have been estimated inclusive of a 30% contingency. Total sustaining capital over the LOM is projected to be $52 M. AMC notes that some aspects of the capital estimation have been done to a much greater degree of detail than may be regarded as typical for a PEA estimate.

Average operating costs of $214 /t and $519 /oz have been estimated. Mining operation costs make up over 70% of the envisaged total operating expenditure which, to a large degree, is a reflection of the labour-intensive mining method. The estimated manpower numbers also reflect provision for the degree of uncertainty that lode-style mining can present from an operations point of view.

Page 41

Using the base case parameters of gold price US$1,100 /oz, exchange rate of Can$1 = US$1, discount rate of 5%, and gold processing recovery of 92.5%, the PEA shows (pre-royalty and pre-tax) an NPV of $433 M and an IRR of 28%. Using a gold price of US$1,500 /oz and with other parameters unchanged, the PEA shows an NPV of $933 M and an IRR of 48%.

As is not unusual for this style of gold deposit, the average grades estimated for the resources (and, therefore, for the mining scenario) have a significant dependency on higher grade drillhole intercepts. AMC considers that a key challenge for the Project will be to thoroughly understand the character of the mineralization and, from this, to develop the ability to readily locate and mine, with optimum dilution, such higher grade areas. AMC believes that this aspect of the Project probably presents both its greatest risk and greatest reward potential.

An enhanced degree of understanding of the zone and mineralization characteristics may also further facilitate the interpretation of exploration drilling data in terms of quantification of mining potential.

A further feature of lode-style deposits is that the generation of significant quantities of reserves may require a much greater degree of delineation drilling and, therefore, expense than for other more uniformly distributed mineralization.

Efforts made by Rubicon to develop site infrastructure have resulted in an excellent platform on which to move the Project towards a potential mining operation.

Mine design parameters have included a 45 m thick bedrock crown pillar between the uppermost workings and the sediment base in the East Bay of Red Lake. A stable geotechnical environment with little or no major faulting, structure or stress issues has been assumed. AMC believes that these are reasonable assumptions for the rock types and conditions observed in the ongoing advanced exploration operations to-date, but further geotechnical and hydrological assessment will be required in the next phase of the Project.

Relative to the location uncertainty associated with lode-style deposits, a variety of mining approaches, with possibly significant equipment capital and maintenance expense, may be necessary. This aspect can present both a risk and an opportunity.

Achievement of an average production rate of 1250 tpd will be dependent on having development sufficiently advanced and ore location sufficiently understood to provide a large number of available and viable stoping areas.

Consequent with the above aspects of lode-style mining, high operating costs can be a significant risk.

Gold recovery estimates to date are dependent on a limited number of samples. Additional testing over a much broader sample range will be required in the next project phase. Gold recovery can present both a potential risk and a potential opportunity for the Project.

There do not appear to be any permitting, community or environmental issues that would be a major constraint to the project.

The historical McFinley Mine area may provide opportunity for additional resources and early production.

Page 42

Drilling in targeted areas below 305L should allow upgrading of resources that are currently in the Inferred category.

Further exploration down dip and along strike may identify additional resource potential. In the case of the area immediately above the 1464L, more drilling is warranted to provide greater support for the higher grade Inferred resources currently identified. This may allow a higher-grade mining scenario to be envisaged in those areas.

In the later stages of the conceived mining program, and subject to gaining additional geotechnical knowledge and understanding of the crown pillar area in the context of an operating mine, and a very rigorous analysis and risk assessment, it is possible that some of the lower portion of the crown pillar area could be mined.

Recommendations

AMC recommends that the Project work continue on several levels that will serve to better understand the deposit and its practical implications for conceived future mining. Several specific recommendations are made by AMC, These are outlined below, together with others that are based on Rubicon’s advice that it considers it important at this stage of the project to test opportunities for increasing the tonnage of mineral resources and to continue its progress towards a position where it can readily move to a production status,

1. Engage a specialist to undertake a structural study of the deposit; this would include undertaking some oriented core drilling.

2. Improve geological understanding of the key characteristics of the deposit as they relate to potential mining by:

a. developing drifts for local diamond drilling in at least two areas, with drives nominally parallel to, and around 25 m from, the mineralization to be drilled. The drifting would be configured to serve both for definition drilling and for possible, future mining access.

b. from the above drifts, conducting fan drilling in a vertical plane across the mineralization on sections at nominal 10 m spacing.

c. drifting on and across mineralization in each area in a systematic manner and relating to above fan drilling via mapping, face sampling and subsequent assaying.

3. Improve knowledge of the resource as a whole by:

a. executing a delineation diamond drilling program in known zones focusing on Indicated Resources.

b. executing a diamond drilling program on Inferred Resources aimed at upgrading to Indicated Resources.

Page 43

c. executing a deep diamond drilling program of the broader Phoenix area.

Each of the above programs would be carried out in two phases with commencement and execution of the second phase being dependent on results from the first.

4. Conduct further mining studies with respect to:

a. assessing opportunities for early ore production by optimizing the schedule, including ramp from surface and possibilities in the historical McFinley area

b. considering alternative mining methods such as mechanized cut and fill and long-hole stoping relative to improved understanding of the resource.

5. Undertake further geotechnical assessment as a greater understanding is gained of the mineralization and the impact that may have on mining geometry, extraction sequence and crown pillar size requirements. In parallel with this work, also complete relevant hydrogeological studies.

6. Undertake further metallurgical testwork on samples from different areas of mineralization to improve understanding of the range of possible gold recoveries. As part of this exercise, implement a metallurgical test program aimed at defining a fully optimized processing circuit that considers ore blends anticipated to be delivered to the mill.

7. Undertake further study on the characteristics of likely mill tailings with respect to use for paste fill.

8. Update the ventilation study to reflect projected production rate and increased depth.

9. Continue working with Aboriginal Groups, undertake further environmental studies and proceed with related procurement as required.

10. Based on Rubicon’s advice that it considers it important at this stage of the project to test opportunities for increasing the tonnage of mineral resources, extend the shaft 200 m below the current elevation, develop additional accesses and drill stations, install a rockbreaker station and refuge station and undertake further exploratory diamond drilling from and around the 488 L.

11. Based on Rubicon’s advice that it considers it important to continue to move towards a production ready status, purchase long lead items for the anticipated mill.

The total estimated cost of these recommendations is approximately $61 M.

AMC advises that these recommendations be implemented in a phased manner. AMC anticipates that the total program would take 12-18 months to complete, with each phase being of the order of 6-9 months in length.”

Permitting Summary

Although the Company’s Production Closure Plan was approved by the MNDM on December 2, 2011, and the remaining permits required for the projected production phase (as contemplated in the PEA) of the Phoenix Gold Project were received in Q1 of 2012, the operations of the Company will still require certain non-material approvals from various governmental authorities as the development continues.  There can be no assurance that the Company will be able to obtain all necessary currently unanticipated licenses and permits that may be required to carry out exploration, development and mining operations at its projects, on reasonable terms or at all. Delays or failure to obtain such licenses and permits, or failure to comply with the terms of any such licenses and permits that the Company does obtain, could have a material adverse effect on the Company.  Rubicon is required to comply with all permits in hand which includes the obligation to continue to consult with local communities, including First Nations and the relevant Métis communities.

As of the date of this AIF, Rubicon is currently fully permitted to complete its current $55 million exploration and development program, as per the press release dated October 19, 2011, and the remaining permits required for the projected production phase of the Phoenix Gold Project, as contemplated in the PEA, were received in Q1 of 2012 (as announced by the Company on March 21, 2012).

The Canadian Environmental Assessment Agency confirmed in writing on June 30, 2011 that there are no triggers for a federal environmental assessment associated with the currently defined Phoenix Gold Project, as contemplated in the PEA.

As announced by the Company on October 20, 2011, the Company secured grid power allocation (up to 5.3MW) from Hydro One for the Phoenix Gold Project. The Company completed its power line connection and infrastructure, and obtained the requisite approvals and agreements from adjacent surface rights holders. Rubicon has initiated the design work with Hydro One for the required upgrades to provide Rubicon with an additional ~4.7MW.

Exploration Expenditures

Over the past three years, the Company has incurred approximately $145.6 million in exploration and development expenditures on its Phoenix Gold Property.

2011 Exploration

The Company drilled a total of 81,801.2 metres during 2011 on the Phoenix Gold Property. All of this drilling was focused on the F2 Gold System.

Mineralization within the F2 Gold System occurs near a major structural setting within the ultramafic-mafic volcanics rock package. This setting is interpreted to be analogous to major deposits in the Red Lake gold district. Gold in the F2 Gold System is best developed within mafic volcanic units as multiple and complex quartz veins, breccias and silica replacement zones typically containing visible gold and trace to 3% sulphide. Results to date indicate that high-grade gold lenses or shoots are developed within discrete gold-bearing structures that can also host thick, lower grade intervals. Low grade gold mineralization and alteration in host rocks is an excellent predictor of the potential for nearby economically significant gold mineralization as borne out by drill results to date. The overall mineralized envelope suggests a steep plunge to the southwest. These interpretations are preliminary in nature and relationships between the various styles of mineralization are complex. Additional drilling is required to gain a better understanding of gold distribution, geometry and controls on mineralization within the F2 Gold System.

Page 45

Since discovering the F2 Gold System in late February 2008, significant gold mineralization has now been intersected over a vertical distance of 4,767 feet (1,453 metres) and over an interpreted strike length of approximately 3,937 feet (1,200 metres). Based on the diamond drilling results, a set of geological sections through the F2 Gold System has been generated. These demonstrate that major geological units are parallel to foliation, i.e. they are sub-vertical to steep west dipping and host gold mineralization which can be correlated for approximately 1,200 metres along strike northeast and to depths of approximately 1,500 metres where such deeper drilling has been carried out.

The Technical Report contains a Preliminary Economic Assessment and updated mineral resources.  The Technical Report updates mineral resources stated in the Amended Report, which amended and superseded initial mineral resources in a January 11, 2011 technical report (see “Material Mineral Projects”).

Qualified Person

The 2011 exploration work in Red Lake was supervised by, and the technical information concerning the Company’s Red Lake properties in this AIF was prepared by or under the supervision of Terry Bursey, P.Geo., Regional Manager of the Company and a Qualified Person under the definition of NI 43-101.

OTHER PROJECTS

The following descriptions relate to the Company's non-material properties

Other Red Lake projects (2009 –2011)

Over the past three years, the Company spent approximately $2.8 million in exploration on its other Red Lake properties.  Additional exploration was also funded by the Company’s option and joint venture partners.

Adams Lake Property

The Adams Lake property comprises 35 unpatented mining claims (236 units) located approximately 5 kilometres east of the Red Lake mine complex. Titan-24 geophysical surveys support the presence of large structures extending to depth that are thought to be similar to structures which host gold mineralization elsewhere in this prolific gold district. The Company conducted a three-hole reconnaissance program at Adams Lake in 2008.  The drilling confirmed the presence of prospective Balmer rocks and validated the Titan-24 survey in the area below iron formation located close to the Balmer formation contact. The Company believes these results confirm the presence of prospective units in a major fold closure at Adams Lake. Due to the focus on the Phoenix Gold Project, drilling at Adams Lake was curtailed to allow maximum resources to be directed to the F2 Gold System discovery. The property is currently inactive.

Page 46

East Bay Property

The East Bay property comprises 43 unpatented mining claims (123 units) that occupies four-kilometres of strike length of the East Bay Trend, immediately adjacent to, and on strike with, the GAZ zone of the East Bay property of Goldcorp/Premier Gold (an inferred resource of 1.4 million tonnes grading 8.0 g/t gold - Source: Premier Gold News Releases). The East Bay claims are underlain by the East Bay ultramafic body, an important unit associated with gold elsewhere along the trend, including at the Phoenix Gold Project. East Bay is considered strategic and a priority target.  Exploration plans for East Bay in 2009 were postponed to allow maximum resources to be directed to the F2 Gold System discovery.  In 2010, the Company conducted a Titan-24 DCIP & MT survey consisting of a grid of five 2.4 kilometre lines to assist in the targeting of future drill programs.  During 2011, the Company did not incur any expenditures at the East Bay property.

DMC Property

The DMC property comprises 130 contiguous unpatented mining claims (263 units) located 7.5 kilometres northwest of the Red Lake mine complex and covers over 17 kilometres strike length of the northeast-trending Red Lake Greenstone Belt (“RLGB”). The property is considered strategic to the Company and a Titan-24 geophysical survey covering the core of the DMC property was completed in April 2009. This survey technique has the potential to provide targeting information from surface to up to one kilometre below surface. At the Company’s Phoenix Gold Project, similar Titan-24 surveys are correlated with the F2 Gold System mineralized sequence. Rubicon views Titan-24 geological surveys as potentially useful in identifying new targets beyond the Phoenix Gold Project itself.  The results of the Titan-24 survey were evaluated in the fall of 2009 and used as a targeting tool for a 2010 seven drill hole program conducted.  An additional Titan-24 survey consisting of a grid of five 2.4 kilometre lines was conducted in Q1 of 2010.  Approximately $25,000 was expended on the DMC property during the current year for property agreement maintenance.  No exploration work on the property was conducted in 2011 as the Company’s current focus is the Phoenix Gold Project.

Humlin Property

The Humlin property comprises 31 unpatented mining claims (294 units) located in Fairlie Township.  No work was conducted on the property in 2011.

Slate Bay Property

The Company has a 100% interest in 30 unpatented mining claims (153 units) located in McDonough and Graves Townships.  Slate Bay, located in the core of Red Lake, is a large property with extensive gold-bearing highly prospective Balmer stratigraphy, which includes key mafic-ultramafic contacts in proximity to a regional scale angular unconformity.  The setting is analogous to that at the producing mines in the camp.  Titan-24 deep penetration IP surveys were performed over a portion of the Slate Bay property in the first quarter of 2010 and final data was received in the second quarter of 2010.  The Company is using this data in conjunction with historical drilling and magnetic surveys to refine future drill targets.  No exploration work on the property was conducted in 2011.

Advance Property

The Advance property comprises 13 patented mining claims (approximately 39 ha) in the Todd Township of west Red Lake.  The property is inactive but remains a prospective target and is adjacent to properties being actively explored and drilled by competitors.

Red Lake North Property

The Company had optioned a 55% interest in its 48 unpatented mining claims (337 units) that comprise the Red Lake North Project located in Bateman, Black Bear, Coli Lake and McDonough Townships to Solitaire Minerals Corporation (“Solitaire”).   Solitaire was required to spend $750,000 by December 31, 2011 (as amended in 2009, 2010 and 2011) in order to maintain its option in good standing.  Solitaire was not able to do so.  By way of letter dated January 5, 2012, Solitaire confirmed that it would not be further pursuing its option in these subject properties.

Page 47

Westend Property

The property is comprised of 3 unpatented mining claims (11 units) and is inactive.

Properties Under Option or Joint Venture

Wolf Bay Property

The Wolf Bay property comprises 23 unpatented mining claims (108 units) located in the Todd and Hammell Lake Townships of west Red Lake.  Rubicon controls a 100% interest in five of these claims and a 50% interest in the remaining 18 claims.  The property is currently inactive.

McCuaig JV Property

The McCuaig property comprises three unpatented mining claims (10 claim units) seven kilometres northwest of the Red Lake mine complex and is a joint venture between Rubicon (60%) and Golden Tag Resources Ltd. (40%). The property is strategically located in the heart of the Red Lake gold camp and is underlain in part by the Balmer stratigraphy of the RLGB. The geological setting is considered to be analogous to the Bruce Channel mineralization previously being explored on the adjacent Gold Eagle Mines property (now controlled by Goldcorp Inc.) and to the setting of the major gold deposits of the camp hence is well located for future exploration. Notwithstanding the foregoing, the Company’s focus at the Phoenix Gold Project meant that no work was carried out in 2009.  During the first quarter of 2010, a Titan-24 survey was completed on the McCuaig property in conjunction with surveys completed over the adjacent DMC property.  No work was conducted on the property in 2011.

English Royalty Division

The English Royalty Division refers to Rubicon’s active program of acquiring mineral properties for the purpose of optioning out to other mining exploration companies.  As such, it provides the Company with an ongoing revenue stream of cash and shares and a residual royalty position in all the properties acquired.

During the year ended December 31, 2011, the Company recorded gross cash and share receipts of $1,743,234 from English Royalty Division options.   

For further information please refer to the financial statements for the year ended December 31, 2011 of the Company.

U.S. Projects

Nevada and Utah

In 2007, Rubicon acquired a 225,000 acre land package in Elko County, Northeastern Nevada and 608 acres in Box Elder County, Northwestern Utah from Lexam Explorations Ltd. for approximately US$6 million payable in shares of the Company. Exploration of this property is in the preliminary stage.

As at December 31, 2011, Rubicon has spent $1,008,176 on its Nevada properties.  As at December 31, 2011, West Kirkland has represented that it has spent US$986,254.57 pursuant to an option agreement described below, and that it intends to complete its Year 1 US$2 million expenditure requirement before the first anniversary date (June 23, 2012).

Page 48

This area of Nevada is starting to be subject to more exploration following recent discoveries and ongoing development by others in the region. Rubicon carried out an extensive airborne magnetic and radiometric survey designed to aid in the development of target areas. This was supplemented by field mapping, prospecting and the completion of a regional stream sampling program and ASTER image analysis to aid in target selection. Reconnaissance field mapping and a stream sediment sampling program was carried out in 2009.

The property is considered to be prospective for ‘Long Canyon’ style gold mineralization, which refers to a deposit in a similar geological setting currently being developed by Newmont Mining Corporation. Exploration on the properties is being carried out by West Kirkland pursuant to an option agreement with the Company, the general details of which are as follows:

• On June 23, 2011, the Company entered into an agreement with West Kirkland whereby that entity can earn a majority interest in all the mineral rights held by Rubicon in the states of Nevada and Utah, covering approximately 351 square miles (909 square kilometres) along the Long Canyon Trend of north eastern Nevada.

•           West Kirkland can earn:

• 51% of the Company’s interest in the Company’s 100% owned lands;

• 68% of the Company’s interest in the Company’s 75% owned lands; and

• 60% of the Company’s interest in the Company’s less than 75% owned lands;

by expending US$15 million over a four year period. West Kirkland is committed to make minimum expenditures of US$2 million in the first year.

• On the properties where Rubicon owns a 100% interest, West Kirkland can further increase its interest to 60% by completing a pre-feasibility study or spending an additional US$4 million on exploration and development work.

Alaska

During 2007, as part of the transaction with companies owned or controlled by Robert R. McEwen, the Company acquired a 513,000 acre land package in Alaska, southeast of Fairbanks for approximately $22 million, through the issuance of common stock. The lands surround the Pogo Gold Deposit, owned by Sumitomo Metal Mining Co., Ltd. (85%) and Sumitomo Corp. (15%). Approximately 1/2 of the package is 100% owned by Rubicon (New Horizon Claims) and the other 1/2 consisted of an option to acquire up to a 75% interest in lands held by Kiska (formerly Rimfire Minerals Corporation). In March 2011, the Company advised Kiska that they would be terminating the option.

Total exploration expenditures in Alaska since acquisition in 2007 amounted to $6.4 million.   All commitments for Alaska exploration under the McEwen transaction were met in 2008.  No exploration work was carried out on the property during 2009, 2010 or 2011.

Page 49

The Alaska claims are at an early stage of exploration and, accordingly, work has focused on mapping and prospecting of this large area to identify and prioritize targets for follow-up. The program also included a minor diamond drilling program testing priority areas. The remaining exploration targets are high-grade gold deposits of the Pogo type. The Pogo deposit has a distinctive geochemical expression (gold, bismuth, arsenic) and was discovered as a result of drill-testing stream silt anomalies and a multi element soil anomaly.

Due to its focus on the Phoenix Gold Project, the Company has elected to reduce its exploration in Alaska and seek partnerships to advance exploration but continues to view its Alaska holdings as prospective for new high grade gold discoveries in the area.

The Alaska projects are under the supervision of Curt Freeman, MS, P.Geo., Independent Consultant and a Qualified Person as defined by NI 43-101.

DIVIDEND RECORD AND POLICY

The Company has not paid any dividends since incorporation and it has no present intention of paying dividends on its common shares as it anticipates that all available funds will be invested to finance the growth of its business.  The directors of the Company will determine if and when dividends should be declared and paid in the future based on the Company’s financial position at the relevant time. All of the common shares are entitled to an equal share of any dividends declared and paid.  There are no restrictions on the Company’s or its subsidiaries’ ability to pay dividends.

OTHER SHARE ISSUANCES

(a) is, as at the date of this AIF, or has been within the 10 years before the date of this AIF, a director or executive officer of any company (including the Company and any personal holding companies) that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangment or compromise with  creditors or had a receiver, receiver manager or trustee appointed to hold its assets; or

Page 52

(b) has, within the 10 years before the date of this AIF, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement, or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold the assets of the director, executive officer or shareholder.

Penalties and Sanctions

(b) any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor making an investment decision.

Conflicts of Interest

The Company’s directors and officers may serve as directors or officers of other companies or have significant shareholdings in other resource companies and, to the extent that such other companies may participate in ventures in which the Company may participate, the directors of the Company may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation.  In the event that such a conflict of interest arises at a meeting of the Company’s directors, a director who has such a conflict will abstain from voting for or against the approval of such participation or such terms.  From time to time, several companies may participate in the acquisition, exploration and development of natural resource properties thereby allowing for their participation in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in respect of any one program.  It may also occur that a particular company will assign all or a portion of its interest in a particular program to another of these companies due to the financial position of the company making the assignment.  In accordance with the laws of British Columbia, the directors of the Company are required to act honestly, in good faith and in the best interests of the Company.  In determining whether or not the Company will participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider the degree of risk to which the Company may be exposed and its financial position at that time.

Page 53

The directors and officers of the Company are aware of the existence of laws governing the accountability of directors and officers for corporate opportunity and requiring disclosures by the directors of conflicts of interest and the Company will rely upon such laws in respect of anydirectors’ and officers’ conflicts of interest or in respect of any breaches of duty by any of its directors and officers.  All such conflicts must be disclosed by such directors or officers in accordance with the laws of British Columbia and the Company expects they will govern themselves in respect thereof to the best of their ability in accordance with the obligations imposed upon them by law.  The directors and officers of the Company are not aware of any such conflicts of interests or potential conflicts of interests other than the relationship that David R. Reid has as a director of the Company and as a partner in Davis LLP, one of the legal advisors to the Company.

PROMOTERS

There is no person or company that has been, within the two most recently completed financial years or during the current financial year, a “promoter” of the Company or a subsidiary of the Company, as such term is defined in the British Columbia Securities Act.

Reliance on Certain Exemptions
