Uranium Resources, Inc. Announces Intervenors Appeal NRC Decision Confirming Crownpoint, NM Project Safety.

LEWISVILLE, Texas -- Uranium Resources, Inc. (OTCBB: URRE) announced today that intervenors filed an appeal in the United States Court of Appeals for the Tenth Circuit related to the favorable rulings from the United States Nuclear Regulatory Commission ("NRC") regarding the Company's license for the proposed development of an in-situ recovery uranium project at its Crownpoint Uranium Project in Church Rock and Crownpoint, New Mexico. The appeal was filed on February 12, 2007.

NRC issued a license in 1997 to Hydro Resources, Inc., (HRI) a wholly-owned subsidiary of URI, so it may initiate uranium recovery activities at the Crownpoint Project. Several private groups intervened and requested an administrative hearing regarding the viability of HRI's project and the bases for NRC's issuance of the license. These parties were granted an administrative hearing before NRC's Atomic Safety and Licensing Board. In December 2006, the five NRC Commissioners issued the final decision in which it was determined that the Crownpoint Project was adequately protective of public health and safety. The intervening parties are comprised of two New-Mexico-based non-profit organizations and two residents of Pinedale, New Mexico.

The Company will vigorously defend its license.

"From the time we first submitted our application to license our Church Rock and Crownpoint properties fifteen years ago, the NRC and its Atomic Safety and Licensing Board (ASLB) have examined, and reexamined, HRI's proposed in situ recovery mining projects in great detail," said Dave Clark, President and COO of Uranium Resources, Inc. "The regulatory experts have repeatedly deemed our New Mexico projects to be safe."

During the licensing process, an exhaustive, multi-agency investigation was conducted, and found that HRI's projects did not jeopardize the well-being of local area residents and the environment. In addition, the opposition groups appealed each NRC decision, prompting even further analysis of HRI's projects. In every instance, the findings supported the initial determination that HRI's projects were safe.

"Safety is the core of the issue. Our technology has been proven over the past three decades, and the safety of our project has been upheld," added Mr. Clark.
