Uranium Resources, Inc. provides second quarter 2011 update

Los Finados Exploration Project Continues to Move Forward

URI’s objectives in Texas are to explore for and develop a larger reserve base, advance current properties through licensing and permitting, lease additional targeted properties and work with its customers to redefine the terms of its sales agreements to enable better margins and greater likelihood of returning to production in Texas.

• In May, URI entered into a joint venture agreement with Cameco Texas, Inc. (“CTI”), a subsidiary of Power Resources, Inc., which is a subsidiary of Cameco (NYSE: CCJ), for a three-phase, three-year exploration program on the Los Finados property, which encompasses 54,847 acres in Kenedy County, Texas. URI also secured the exploratory drilling permit from the Surface Mining and Reclamation Division of the Railroad Commission of Texas.
• Having completed the joint venture agreement and obtaining the drilling permit, on June 21, URI initiated the first phase of the drilling program. This phase of the exploratory drilling, which is expected to be completed by the end of September at a cost of approximately $1 million, will be done using a widely and evenly spaced program covering a grid designed to test the potential for uranium mineralization over the entire area. Specifically, the objective is to identify oxidation-reduction interfaces within the wide-spaced drilling. To date, URI has completed 10 holes averaging 1,250 feet each.

Don Ewigleben, President and CEO of URI, commented, “Less than ideal drilling conditions are resulting in somewhat higher than expected costs thereby reducing the number of potential holes drilled in the first phase. Nonetheless, we are still on track to have the drilling for the first phase completed by the end of September. As we have noted previously, based on water sampling tests, we believe this green field exploration site should be an excellent uranium prospect.”

• Given current uranium pricing and existing unfavorable sales contracts, the Company does not expect to return to production in Texas in 2011. Currently, the Company has approximately 664,000 identified pounds of in-place mineralized uranium material that could be produced over a two- to three-year period.
• The Company has focused on reclamation activities in Texas since its two remaining operating wellfields were fully depleted in June 2009.
  • Kingsville Dome (KVD): Treated over 120 million gallons of groundwater in the quarter, and since December of 2004, over 1.5 billion gallons of water have been treated. URI completed restoration in PA1 and PA2 and the fields are now in stabilization testing. Full scale restoration has begun at the remaining KVD production area.
  • Rosita: The first two production areas completed restoration and remained in stabilization throughout 2010 and into 2011. Documents have been filed with the State of Texas for final restoration approval.
  • Vasquez: Treated over 76 million gallons of groundwater in the quarter in PA1 which should be completed in 2012.

Feasibility Study Progressing in New Mexico

URI’s focus in New Mexico is on the completion of its feasibility study to advance its Churchrock/Crownpoint project. The evaluation includes the economic analysis and operating requirements for the in situ recovery of its uranium assets that are amenable to this lower cost mining method which includes the wellfields, satellite plants and a central processing plant at Crownpoint.

• Given the need to accelerate the significant engineering and design requirements identified through the feasibility study activities, URI now expects construction of its Churchrock/Crownpoint ISR wellfield and processing facilities later in 2012, assuming that the necessary financial resources are in place and uranium prices have recovered.
• The Company continues to target production in mid-2013. Production will be dependent upon the speed of construction activities and availability of capital equipment. Given the most recent projections, construction costs will likely be on order of $50 million or more, dependent upon the various scenarios under consideration.
• URI holds the necessary NRC License, EPA Aquifer Exemption, State of New Mexico Water Rights and Underground Injection Control Permit to allow Church Rock Section 8 development to begin according to our plan. In June, URI received confirmation from the New Mexico Environment Department (“NMED”) that its discharge plan is in timely renewal and that the NMED is currently conducting technical review of its renewal application. In July, Eastern Navajo Dine Against Uranium Mining filed a complaint claiming NMED misinterpreted its own regulations governing the ground water discharge permits. URI will intervene in this case.

Mr. Ewigleben, noted, “The feasibility study is moving along as planned and we are evaluating various scenarios specific to our priority production property, Church Rock Section 8 which has 6.5 million pounds of in-place mineralized uranium material. We are planning on accelerating our engineering activities in order to stay on target.”

Liquidity Position

Cash at June 30, 2011 was $8.2 million compared with $11.1 million at March 31, 2011 and $15.4 million at the end of 2010. The decrease from the sequential first quarter reflects ongoing reclamation activities in Texas, the costs associated with the feasibility study and $500,000 of funding to collateralize URI’s financial surety obligations. URI’s cash balance at July 31, 2011 was approximately $7.3 million.

Mr. Ewigleben concluded, “Given our plan to accelerate our engineering activities for our Churchrock project and our cash requirements for the evaluation of various strategic initiatives, we are currently weighing various alternatives and evaluating the timing associated with the need to raise additional capital.”

Teleconference and Webcast

URI is hosting a conference call and webcast today at 11:00 a.m. ET. During the call, management will provide an update on URI’s strategies, outlook, and progress in advancing its Texas and New Mexico properties. A question-and-answer session will follow.

About Uranium Resources, Inc.

Uranium Resources Inc. explores for, develops and mines uranium. Since its incorporation in 1977, URI has produced over 8 million pounds of uranium by in-situ recovery (ISR) methods in the state of Texas where the Company currently has ISR mining projects. URI also has 183,000 acres of uranium mineral holdings and 101.4 million pounds of in-place mineralized uranium material in New Mexico and a NRC license to produce up to 1 million pounds of uranium per year. The Company acquired these properties over the past 20 years along with an extensive information database of historic mining logs and analysis. None of URI’s properties is currently in production.

URI’s strategy is to fully exploit its resource base in New Mexico and Texas, expand its asset base both within and outside of New Mexico and Texas, partner with larger mining companies that have undeveloped uranium or with junior mining companies that do not have the mining experience of URI, as well as provide restoration expertise to those that require the capability or lack the proficiency.

Uranium Resources routinely posts news and other information about the Company on its Web site at www.uraniumresources.com.
