Uranium Resources, Inc. Provides Update on Churchrock Project

LEWISVILLE, Texas--(BUSINESS WIRE)--June 1, 2009--Uranium Resources, Inc. (NASDAQ: URRE) (URI), announced that it plans to file today a petition with the U.S. 10^th Circuit Court of Appeals for an en banc review regarding its ruling on April 17, 2009 that determined URI’s Section 8 in Churchrock, New Mexico is Indian Country and, therefore, comes under the jurisdiction of the U.S. Environmental Protection Agency (USEPA) for the issuance of an Underground Injection Control Permit (UIC). The New Mexico Environmental Department has previously issued a UIC permit to the Company, which continues to be in timely renewal.

Dave Clark, President and CEO of URI, noted, “As we’ve stated previously, we intend to proceed in a manner that will allow us to obtain an effective UIC permit. Our objective remains to resolve issues with the Navajo Nation regarding uranium mining in New Mexico, so we can be well positioned to begin production as quickly and as safely as possible.”

URI has a Nuclear Regulatory Commission license to mine 15 million pounds of in-place mineralized uranium material at Churchrock using in situ recovery methods. An effective UIC permit from the appropriate governmental agency is the final permit needed before development can begin.
