(NASDAQ: URRE) (URI), announced the summary results of the feasibility study for its Churchrock Section 8 Project located in the northwestern New Mexico’s historic Grants Mineral Belt.

A presentation summarizing the feasibility study is available on URI’s website, www.uraniumresources.com, under Projects.

Churchrock Section 8 Feasibility Study Highlights

• 6.5 million pounds of mineralized uranium material at a grade of 0.11% U₃O₈
• In situ recovery is the preferred uranium extractive technology for the project
• Assumed recovery rate of 67% results in production of 4.4 million pounds
• Projected six-year production life with peak production at more than one million pounds annually
• Pre-production development costs estimated at $35 million
• Direct operating costs are estimated to be $20 to $23 per pound of U₃O₈ produced

"The completion of the Churchrock Section 8 feasibility study is a measurable step forward for URI toward our goal of realizing uranium production in New Mexico" stated Terence J. Cryan, Interim President and CEO of URI. “A technically and economically relevant project for the U.S. uranium industry, Churchrock remains one of our primary strategic initiatives. We are currently working to both de-risk and further enhance the economics of the project. This includes our negotiations with the Navajo Nation regarding a comprehensive agreement and efforts to reach agreements with current royalty holders. We believe this project will create significant value for our shareholders.”

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. URI has over 206,600 acres of uranium mineral holdings and 152.9 million pounds of in-place mineralized uranium material in New Mexico and an NRC license to produce up to 1 million pounds of uranium per year.

URI’s strategy is to fully develop its resource base in New Mexico and Texas, expand its asset base both within and outside of New Mexico and Texas, and partner with larger mining companies that have undeveloped uranium assets 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.
