PROSPECTUS SUMMARY

This summary highlights selected information contained elsewhere in this Prospectus or incorporated into this Prospectus by reference.  This summary may not contain all of the information that may be important to you in considering an investment in our common stock.  You should carefully read the entire Prospectus, including the documents incorporated by reference, before making and investment decision.   Except for historical information contained in this Prospectus, the matters discussed herein contain forward-looking statements, made pursuant to the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including management’s expectations regarding the Company’s reserves and mineralized uranium materials, timing of receipt of mining permits, production capacity of mining operations planned for properties in South Texas and New Mexico and planned dates for commencement of production at such properties. Such forward-looking statements are inherently uncertain, and investors must recognize that actual results may differ from management’s expectations. Key factors impacting current and future operations of the Company include the spot price of uranium, weather conditions, operating conditions at the Company’s mining projects, government regulation of the mining industry and the nuclear power industry, the world-wide supply and demand of uranium, availability of capital, timely receipt of mining and other permits from regulatory agencies and other matters indicated in “Risk Factors” starting on page 2.

Our Company

We were organized in 1977 to mine uranium in the United States by using an in situ recovery (ISR) mining method, a process by which groundwater is fortified with an oxidizing agent and pumped into the ore body causing the uranium contained to dissolve.  The resulting solution is then pumped to the surface where it is further processed into uranium concentrates that are shipped to a conversion facility for sale to our customers.  This ISR process is generally more cost effective and environmentally benign than conventional mining techniques.

As of December 31, 2006, we had 51,791,339 shares of Common Stock outstanding. On that date, there were 175 holders of record.

As of December 31, 2006, we had 121 employees, including eight geologists, ten engineers and two certified public accountants. We have field offices at Kingsville Dome, Vasquez, Rosita and Crownpoint, New Mexico.

RISK FACTORS

Investing in our Common Stock will provide you with an equity ownership in Uranium Resources. As one of our stockholders, you will be subject to risks inherent to our business. The trading price of your shares will be affected by the performance of our business relative to, among other things, competition, market conditions and general economic and industry conditions. The value of your investment may decrease, resulting in a loss. You should carefully consider the following factors as well as other information contained in this Prospectus before deciding to invest in shares of our Common Stock.

The factors identified below are important factors (but not necessarily all of the important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement made by, or on behalf of, the Company. Where any such forward-looking statement includes a statement of the assumptions or bases underlying such forward-looking statement, we caution that, while we believe such assumptions or bases to be reasonable and make them in good faith, assumed facts or bases almost always vary from actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, the Company, or its management, expresses an expectation or belief as to the future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement of expectation or belief will result, or be achieved or accomplished. Taking into account the foregoing, the following are identified as important risk factors that could cause actual results to differ materially from those expressed in any forward-looking statement made by, or on behalf of, the Company.

Our ability to function as an operating mining company is dependent on our ability to mine our properties at a profit sufficient to finance further mining activities and for the acquisition and development of additional properties.

Our ability to operate on a positive cash flow basis is dependent on mining sufficient quantities of uranium at a profit sufficient to finance our operations and for the acquisition and development of additional mining properties.  Our failure to achieve or maintain profitable mining operations could have a negative impact on our business and results of operations and could adversely affect the market price of our common stock.

The Navajo Nation ban on uranium mining in Indian country encompasses some of our properties in New Mexico and will adversely affect our ability to mine unless the ban is overturned.

In April 2005, the Navajo Nation Council passed the Diné Natural Resources Protection Act of 2005 prohibiting uranium mining and processing on any sites within Indian Country.  Some of our New Mexico properties have been determined to be Indian country and the status of others as Indian country is in dispute.  We believe that the ban is  beyond the jurisdiction of the Navajo Nation.  However, the ban may prevent us from developing and operating the properties until the jurisdictional issues is resolved.

In February 2007 the USEPA determined that Section 8 of our Churchrock property was Indian country and that the USEPA and not the state of New Mexico has the authority to issue the UIC permits for Section 8 that are a precondition to mining.  We are appealing that decision to the United States Court of Appeals for the Tenth Circuit.  If we are unable to appeal the USEPA’s decision, our mining operations at our Churchrock property could be adversely affected which could have a negative impact on our results of operations.

2

Our inability to obtain financial surety would threaten our ability to continue in business.

Future bonding requirements will increase significantly when future development and production occurs at our sites in Texas and New Mexico. The amount of the bonding for each producing property is subject to annual review and revision by regulators. We expect that the issuer of the bonds will require us to provide cash collateral equal to the face amount of the bond to secure the obligation. If we cannot provide adequate cash collateral to meet bonding requirements, our development and production activities at the affected sites could be adversely impacted.

Because we have limited capital, inherent mining risks pose a significant threat to us.

Because we are small with limited capital, we are unable to withstand significant losses that can result from inherent risks associated with mining, including environmental hazards, industrial accidents, flooding, interruptions due to weather conditions and other acts of nature. Such risks could result in damage to or destruction of our wellfield infrastructure and production facilities, as well as to adjacent properties, personal injury, environmental damage and processing and production delays, causing monetary losses and possible legal liability.

More stringent federal and state regulations could adversely affect our business.

If we are unable to obtain or maintain permits or water rights for development of our properties or otherwise fail to manage adequately future environmental issues, our operations could be materially and adversely affected. We have expended significant resources, both financial and managerial, to comply with environmental protection laws, regulations and permitting requirements and we anticipate that we will be required to continue to do so in the future. Although we believe our properties comply in all material respects with all relevant permits, licenses and regulations pertaining to worker health and safety as well as those pertaining to the environment and radioactive materials, the historical trend toward stricter environmental regulation may continue. Compliance with any material change in laws applicable to us could require significant expenditures of our capital resources, which could have a material adverse effect on our financial condition and results of operations.

The volatility of uranium prices makes long-range planning uncertain and raising capital difficult.

The price of uranium is affected by numerous factors beyond our control, including the demand for nuclear power, political and economic conditions, and legislation and production and costs of production of our competitors.  A significant decrease in the price or uranium could adversely affect the price of our common stock.

The only market for uranium is nuclear power plants world wide, and there are only a few customers.

We are dependent on a small number of electric utilities that buy uranium for nuclear power plants. Because of the limited market for uranium, a reduction in purchases of newly-produced uranium by electric utilities for any reason (such as plant closings) would adversely affect our financial condition and results of operations.

Public acceptance of nuclear energy is uncertain.

Maintaining the demand for uranium at current levels and future growth in demand will depend upon acceptance of nuclear technology as a means of generating electricity. Lack of public acceptance of nuclear technology would adversely affect the demand for nuclear power and increase the regulation of the nuclear power industry, which could have a negative impact on our business.

Our inability to obtain insurance would threaten our ability to continue in business.

We currently have liability and property damage insurance that we believe is adequate. However, the insurance industry is undergoing change and premiums are being increased. If premiums should increase to a level we cannot afford, we could be forced to cease operations.

If we cannot add additional reserves to replace production in the future, we would not be able to remain in business.

Our future uranium production, cash flow and income are dependent upon our ability to mine our current properties and acquire and develop additional reserves. There can be no assurance that our properties will be placed into production or that we will be able to continue to find and develop or acquire additional reserves.  The failure to commence production at existing sites or to develop and acquire additional reserves will have a negative impact on our business and could adversely affect the price of

3

our common stock.

Competition from better-capitalized companies affects prices and our ability to acquire properties and personnel.

There is global competition for uranium properties, capital, customers and the employment and retention or qualified personnel. In the production and marketing of uranium there are about 15 major producing entities, some of which are government controlled and all of which are significantly larger and better capitalized than we are. We also compete with uranium recovered from the de-enrichment of highly enriched uranium obtained from the dismantlement of United States and Russian nuclear weapons and imports to the United States of uranium from the former Soviet Union.  If any of these competitors are successful in competing against the Company, its sales could decline and its margins could be negatively impacted, all which could seriously harm the Company’s business and results of operations.

Industry-wide competition for exploration and development tools could delay production.

Intense industry-wide competition for exploration and development tools can create the shortage of drill rigs, logging trucks and other equipment.  Such shortages could delay our production and negatively impact our operations.

Competition from numerous small companies affects our ability to acquire properties and personnel and retain existing personnel.

There are numerous entities in the market that compete with us for properties and are attempting to become licensed to operate ISR facilities. In addition, we are aware several entities have expressed interest in hiring certain of our employees. To retain key employees, we may face increased compensation costs, including potential new option grants.

Over 56% of our shares of Common Stock is controlled by Principal Stockholders and Management.

Over 56% of our Common Stock is controlled by six stockholders of record. In addition, our directors and officers are the beneficial owners of about 6.8% of our Common Stock. This includes with respect to both groups shares that may be purchased upon the exercise of outstanding options. Such ownership by the Company’s principal shareholders, executive officers and directors may have the effect of delaying, deferring, preventing or facilitating a sale of the Company, a business combination with a third party or other significant corporate transactions.

The availability for sale of a large amount of shares may depress the market price for our Common Stock.

The Company has 51,797,339 shares of Common Stock currently outstanding, all of which are transferable under a Registration Statement on Form S-1, S-8 prospectuses or otherwise. The availability for sale of such a large amount of shares may depress the market price for our Common Stock and impair our ability to raise additional capital through the public sale of Common Stock. The Company has no arrangement with any of the holders of the foregoing shares to address the possible effect on the price of the Company’s Common Stock of the sale by them of their shares.

USE OF PROCEEDS

All net proceeds from the sale of our Common Stock will go the Selling Stockholders selling stock under this Prospectus.  We will not receive any proceeds from the sale of the Common Stock sold by the Selling Stockholders.

PLAN OF DISTRIBUTION

The number of shares registered for resale and covered by this Prospectus is 16,895,994 and represent 32.6% of the total outstanding shares of Common Stock. The shares may be sold from time to time by the Selling Stockholders or by pledgees, donees, transferees or other successors in interest. Such sales may be made in the over-the-counter market at prices and on terms then prevailing or in negotiated transactions.

Brokers may receive compensation in the form of customary brokerage commissions, discounts or concessions from Selling Stockholders in amounts to be negotiated in connection with sales pursuant hereto. Such brokers or dealers and any other participating brokers or dealers may be deemed to be “underwriters” within the meaning of the Securities Act, in connection with such sales and any such commission, discount or concession may be deemed to be underwriting discounts or commissions under the Securities Act.

All costs, expenses and fees in connection with the registration of the Securities will be borne by us. Commissions, discounts and transfer taxes, if any, attributable to the sales of the Securities will be borne by the Selling Stockholders. Certain of the Selling Stockholders have agreed to indemnify the Company, all other prospective holders of the shares registered hereby or any underwriter, as the case may be, and any of the respective affiliates, directors, officers and controlling persons, against certain liabilities in connection with the offering of the shares pursuant to this Prospectus, including liabilities arising under the Securities Act. In addition, we have agreed to indemnify certain of the Selling Stockholders, all other prospective subsequent holders of their shares registered hereby or any underwriter, as the case may be, and any of their respective affiliates, directors, officers and controlling persons, against certain liabilities in connection with the offering of the shares pursuant to this Prospectus, including liabilities arising under the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The Selling Stockholders should be aware that the anti-manipulation provisions of Regulation M under the Exchange Act will apply to purchases and sales of shares of Common Stock by the Selling Stockholders, and that there are restrictions on market-making activities by persons engaged in the distribution of the shares. Under Regulation M, the Selling Stockholders or their agents may not bid for, purchase, or attempt to induce any person to bid for or purchase, shares of our Common Stock while such Selling Stockholders are distributing shares covered by this Prospectus. Accordingly, the Selling Stockholders are not permitted to cover short sales by purchasing shares while the distribution is taking place. The Selling Stockholders are advised that if a particular offer of Common Stock is to be made on terms constituting a material change from the information set forth above with respect to the Plan of Distribution, then to the extent required, a post-effective amendment to the accompanying registration statement must be filed with the Securities and Exchange Commission.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
OF SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted for directors, officers or persons controlling the Company pursuant to applicable state law, the Company has been informed that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the estimated expenses in connection with the issuance and distribution of the securities being registered, all of which are being borne by the Company.

Securities and Exchange Commission registration fee
Legal fees and expense	$	80,000
Accounting fees and expenses	$	10,000
Other	$	7,500
Total	$	97,500

Item 15. Indemnification of Directors and Officers.

Under Delaware law, a corporation may indemnify any person who was or is a party or is threatened to be made a party to an action (other than an action by or in the right of the corporation) by reason of his service as a director or officer of the corporation, or his service, at the corporation’s request, as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees) that are actually and reasonably incurred by him (“Expenses”), and judgments, fines and amounts paid in settlement that are actually and reasonably incurred by him, in connection with the defense or settlement of such action, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful. Although Delaware law permits a corporation to indemnify any person referred to above against Expenses in connection with the defense or settlement of an action by or in the right of the corporation, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, if such person has been judged liable to the corporation, indemnification is only permitted to the extent that the Court of Chancery (or the court in which the action was brought) determines that, despite the adjudication of liability, such person is entitled to indemnity for such Expenses as the court deems proper. The General Corporation Law of the State of Delaware also provides for mandatory indemnification of any director, officer, employee or agent against Expenses to the extent such person has been successful in any proceeding covered by the statute. In addition, the General Corporation Law of the State of Delaware provides the general authorization of advancement of a director’s or officer’s litigation expenses in lieu of requiring the authorization of such advancement by the board of directors in specific cases, and that indemnification and advancement of expenses provided by the statute shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement or otherwise.

The Bylaws of the Company provide for the broad indemnification by the directors and officers of the Company and for advancement of litigation expenses to the fullest extent permitted by current Delaware law. The Company also has entered into indemnification contracts with its directors and officers.

The Company maintains a policy of directors and officers liability insurance which reimburses the Company for expenses which it may incur in connection with the foregoing indemnity provisions and which may provide direct indemnification to directors and officers where the Company is unable to do so.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Act”) may be permitted to directors, officers and controlling persons of Registrant pursuant to the above, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.

Item 16. Exhibits.

See page E-1 for a list of Exhibits filed with this Post-Effective Amendment No. 1.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1)           to file, during any period in which offers or sales of the registered securities are being made, a post-effective amendment to this Registration Statement:

II-1

(i)            to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the “Securities Act”);

(ii)           to reflect in the prospectus any facts or events which, individually or together, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§ 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii)          to include any additional or changed material information on the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

Provided, however, that,

Paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)           that, for determining liability under the Securities Act, each such post-effective amendment shall be treated as a new registration statement of the securities offered, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3)           to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

The undersigned registrant hereby undertakes that, for purposes of determining liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Act”) may be permitted to directors, officers and controlling persons of the small business issuer pursuant to the provisions described in Item 15 above, or otherwise, the issuer has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.

In the event that a claim for indemnification against such liabilities (other than the payment by the small business issuer of expenses incurred or paid by a director, officer or controlling person of the small business issuer in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the small business issuer will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
