Uranium Resources Provides Full Year 2012 Review and Outlines Near-term Initiatives LEWISVILLE, TX, March 15, 2013 --- Uranium Resources, Inc.

(NASDAQ: URRE) ("URI" or the "Company") today provided an update on the Company's activities and financials through December 31, 2012, as well as its strategy and outlook.

Key 2012 and Recent Accomplishments ·         Acquired Neutron Energy, Inc.

("Neutron") in August 2012, adding over 50 million pounds of mineralized uranium material.

·         Substantiated financial and environmental viability of the Churchrock Section 8 Project.

·         Achieved an agreement with the Navajo Nation for temporary access to Section 8.  First step taken in addressing legacy issues surrounding uranium mining in New Mexico.   ·         Expanded and extended its South Texas exploration agreement with a subsidiary of Cameco Corporation (NYSE: CCJ).

·         Recapitalized through a $5 million bridge loan facility with Resource Capital Fund V L.P.

("RCF"), a shareholder rights offering ("Rights Offering") and the pending release of $4.5 million back to URI after securing new surety bonds.

·         Regained compliance with NASDAQ listing standards.

·         Named Christopher M.

Jones as President and CEO effective April 1, 2013.

"We continue to forge ahead and have made sustained progress so far in 2013," stated Terence J.

Cryan, Interim President and CEO of URI.  "In 2012, we expanded our asset base through the acquisition of Neutron which represented a significant consolidation of uranium properties in New Mexico and positioned URI as one of the largest U.S.-based uranium development companies.  A number of key steps relating to our Churchrock Section 8 project were also taken.  We reached an agreement with the Navajo Nation regarding temporary access, a significant first step in an effort to reach a comprehensive agreement and as important, indicated the willingness of both parties to reach a mutually beneficial, long-term solution.  There were two Section 8 property studies completed, the feasibility study and the groundwater study, which substantiated the technical and economic viability of the project, as well as the environmental safety of in-situ recovery (ISR) mining at Section 8.  These are measurable steps forward as we work to realize our goal of producing uranium in New Mexico."  On March 13, 2013, URI announced that its Board of Directors appointed Christopher M.

Jones, P.E., as President and CEO effective April 1, 2013.  Mr.

Jones has more than 30 years experience in the mining industry having successfully lead various mining and production operations, as well as exploration and development projects.  He most recently was President and CEO of Wildcat Silver Corporation, and prior to that, he was the Chief Operating Officer and the Mining General Manger at Albian Sands Energy.

Near-term Objectives Mr.

Cryan noted, "In the fourth quarter we outlined URI's primary areas of focus as we headed into 2013.  During the fourth quarter we were able to significantly reduce our cash burn and stabilized our capital levels using our bridge loan facility, the Rights Offering and the restructuring of our bonding requirements on our South Texas properties.  We will remain diligent in our efforts to preserve capital for the remainder of 2013.

"With construction plans for our Churchrock Section 8 project currently delayed, discussions aimed at reaching a permanent access agreement with the Navajo Nation and with royalty holders of our Section 8, Section 17 and Mancos properties remain a priority in 2013.  Concurrently, in Texas we will continue our exploration efforts with Cameco and look at other opportunities as part of our effort to grow our South Texas asset base and return to production in the state." Advancements in New Mexico        URI's primary focus in New Mexico is advancing the Churchrock Section 8 property, which contains 6.5 million pounds of mineralized uranium material at a grade of 0.11% U3O8 and is covered by the Company's underground injection control permit and NRC license, both of which are in timely renewal.    ·         Neutron Acquisition - URI completed a stock-for-stock transaction to acquire 100% of the equity of Neutron on August 31, 2012 on a debt-free basis.

 The acquisition increased URI's asset base by more than 50 percent to 152.9 million pounds of in-place mineralized uranium material in New Mexico.

·         Section 8 Feasibility Study - Released the summary results of the feasibility study for its Churchrock Section 8 Project at the end of 2012.  ISR is the preferred uranium extraction technology for the project and using an assumed recovery rate of 67% could result in the production of approximately 4.4 million pounds.  Pre-production development costs are estimated at $35 million with direct operating costs estimated to be $20 to $23 per pound of U3O8 produced.

·         Section 8 Groundwater Study - Completed collaborative study with the Navajo Nation and the City of Gallup with results indicating that existing Gallup, Fort Wingate, Rehoboth and Navajo Nation water wells will not be impacted by Section 8 ISR activities, during mining operations or into the future.

·         Agreement with Navajo Nation - Hydro Resources, Inc., a wholly-owned subsidiary of URI, completed a temporary access agreement with the Navajo Nation for its Churchrock Section 8 property providing access for regulatory requirements to include on-site visits with the Nuclear Regulatory Commission.  Focus in Texas: Tecolote exploration project kicks off, Restoration activities ongoing In 2012, URI and Cameco completed Phase II of the joint Los Finados exploration project to include drilling 40 holes at an average depth of 1,327 feet.  On January 7, 2013, URI announced the expansion of its lease agreement in Kenedy County, Texas, to include the Tecolote tract which has approximately 22,700 net acres and that it will be a part of the exploration program with Cameco.  In addition, the Company extended the original lease to 60 months with the election date to lease the acreage for production now being November 30, 2015.  The amended lease agreement requires a minimum exploration obligation of $1.0 million, or 100 exploration wells during Phase III.  Phase IV and Phase V require $1.5 million, or 150 exploration wells, and $2.0 million, or 200 exploration wells, respectively.

In conjunction with the amended lease agreement, URI and Cameco have agreed to extend their amended exploration agreement to a five-phase, five-year exploration program to include Tecolote.  Cameco has committed $4.3 million to increase its interest to 70% in the expanded program and will be the exploration operator for Phase III.  URI secured $9 million in new surety bonds for the benefit of the Texas Commission on Environmental Quality for remediation and reclamation activities at the Company's South Texas projects.  The new bonds required $4.5 million in cash collateral and replaced the existing $9.0 million of fully collateralized financial surety instruments.  The result is that $4.5 million will be released back to URI due to the lower cash collateral requirement.  Groundwater restoration at Kingsville Dome Production Area (PA)1 and PA2 and Rosita PA1 and PA2 has been completed and is currently being monitored for stability.  Final closure of these production areas is targeted for mid- to late-2013.  The Company continues restoration activities with stabilization targeted for the third quarter of 2013 at Kingsville Dome PA3 and fourth quarter of 2013 for Vasquez PA1 and PA2.

Refurbishment of the Kingsville Dome holding ponds is ongoing and URI expects this project to be completed by year-end 2013.

Strengthened Liquidity Position Cash at December 31, 2012 was $4.7 million, after giving effect to the $5 million bridge loan facility with RCF that closed on December 17, 2012, compared with $2.9 million at December 31, 2011.  During 2012, the Company also raised net proceeds of $5.4 million under the existing At-The-Market Sales Agreement ("ATM") with BTIG, LLC.  At February 28, 2013, URI had a total of $9.0 million in share value available for future sales under the ATM.   Subsequent to the end of the fourth quarter, URI raised gross proceeds of approximately $8.9 million, before expenses, from the Rights Offering, which was used to repay the $5.0 million bridge loan from RCF and the remainder of which will be used for general working capital.  URI will also free up $4.5 million in working capital as a result of the collateral requirements of the new surety bonds.  URI incurred cash expenditures from its operating and investing activities during 2012 of $23.4 million.  Reverse Stock Split and NASDAQ Compliance On January 23, 2013 URI conducted a 1-for-10 reverse stock split of its common stock.  The primary purpose of the reverse split was to bring URI into compliance with NASDAQs $1.00 minimum bid price requirement.  On February 6, 2013 the Company was notified that its common stock had maintained a closing price of $1.00 or more for at least ten consecutive trading days and that the Company was in full compliance with NASDAQ listing requirements and therefore will continue to be listed and traded on the NASDAQ Capital Market.

URI also regained compliance with NASDAQ rules requiring the Board of Directors to be comprised of a majority of independent directors and the Audit Committee to be comprised of at least three independent members.
