Uranium Resources, Inc. Announces Termination of Agreement to Purchase Rio Algom Mining LLC

� Provides Update on Rosita Wellfield in Texas

ALBUQUERQUE, NM, June 26, 2008 --Uranium Resources, Inc. (NASDAQ: URRE) (URI), a uranium exploration, development and production company, today announced that it has decided along with Billiton Investment 15 B.V. to terminate URI's agreement to purchase Rio Algom Mining LLC, which was entered into on October 12, 2007. URI had incurred and capitalized $1.2 million in costs associated with the transaction. These costs will be expensed in the second quarter ending June 30, 2008.

Mr. David N. Clark, President and CEO of URI, commented, �We believe this is the best decision for the Company and our shareholders given current market conditions that have prevented us from securing the $180 million needed to finance the acquisition. Although the Rio Algom mill site would have reduced the time to bring conventional mining back to New Mexico, there are viable alternatives for URI and the other New Mexico uranium companies to pursue. We remain open to all such alternatives. For now, we will concentrate our efforts on rebuilding our low cost production potential in Texas while continuing to develop our resources in New Mexico where we have over 101 million pounds of in-place uranium mineralized material."

Mr. Clark continued, �With regard to our New Mexico assets, we have been working closely with state regulators and expect to receive permits in the fall to drill up to 10 exploratory core holes on our Ambrosia Lake property to determine its feasibility for in situ recovery (ISR) mining. If ISR proves viable, Ambrosia Lake will be an excellent New Mexico ISR project, providing new jobs and contributing to the economic growth of the region, utilizing a proven environmentally-safe technology. In the meantime, we will continue our community outreach and education programs to overcome misperceptions about the industry, and URI will use every opportunity to display our commitment to being a responsible corporate and community partner in New Mexico.�

Rosita Update
At URI's Rosita project in South Texas, we have begun the production process by injecting oxygen into the formation. The wellfield originally suffered from low flow rates. While investigating the potential causes, we discovered several wells had poor completions. The screens from these wells were removed and the holes were underreamed before the screens were reset. This process led to a significant increase in the flow rate. As previously stated, the wellfield will need to operate for two to three weeks at full operation before URI can make a determination of its capabilities.

As of June 24, 2008, the Company had produced approximately 187,600 pounds of uranium of which 104,200 pounds had been produced in the second quarter. This was slightly better than URI's previous estimate for the second quarter due to improved production at its Kingsville Dome operation.

The Company also noted that it has recently moved exploratory drill rigs onto its South Rosita property and is conducting exploratory drilling on the portion of the South Rosita property that was acquired earlier this year.
