Uranium Resources Announces Positive Results of Groundwater Study

Uranium Resources, Inc. (NASDAQ: URRE) ('URI?), announced the positive
findings resulting from the Section 8 / Navajo-Gallup Groundwater
Report and Conjunctive Use Evaluation for its Churchrock Section 8
('Section 8?) uranium in-situ recovery ('ISR?) project.

The study results indicate that existing Gallup, Fort Wingate, Rehoboth
and Navajo Nation water wells will not be impacted by Section 8 ISR
activities, during mining operations or into the future. Moreover, the
evaluation concluded that there is no discernible risk that ISR
activities would adversely affect groundwater allocated for the
Navajo-Gallup Water Supply Project.

'This study was a collaborative effort with the Navajo Nation and the
City of Gallup,? stated Mark S. Pelizza, Senior Vice President of
Health, Safety and Environmental Affairs of URI. 'The evaluation
substantiates our belief that ISR mining, specifically at our Churchrock
project, is a safe, environmentally-friendly way to extract uranium.?

Mr. Pelizza added, 'We continue our discussions with members of the
Navajo Nation and its government and believe that this jointly developed
study is a solid step forward to help address their mining concerns.?

The report was prepared by Daniel B. Stephens and Associates, Inc., a
hydrology, engineering and geosciences consulting firm based in
Albuquerque, New Mexico. The firm was selected to conduct the study by
the Navajo Nation and the City of Gallup. The evaluation was conducted
assuming parameters that resulted in faster groundwater migration rates
and placed all future supply wells in locations closer to Section 8 than
are projected. Additionally, consideration was not given to geochemical
processes, which lead to the natural dilution and removal of elements
over time.

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 has
an additional 1.3 million pounds of in-place mineralized uranium
material in Texas and South Dakota. The Company acquired these
properties over the past 20 years along with an extensive information
database of historic drill hole logs, assay certificates, maps and
technical reports. None of URI′s properties is currently in production.

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.
