Uranium Resources, Inc. (NASDAQ: URRE) ('URI?) announced today that the
Surface Mining and Reclamation Division of the Railroad Commission of
Texas granted URI a permit to conduct exploratory drilling on the 54,847
acres in Kenedy County, Texas, known as the "Los Finados Project.′

Don Ewigleben, President and CEO of URI, commented, 'Having completed
our joint venture agreement with Cameco and obtaining this permit; we
are ready to move forward with our drilling program. We are finalizing
our exploration objectives with our partner and expect to commence
drilling sometime this summer.?

URI announced yesterday that it had entered into an exploration
agreement with Cameco Texas, Inc., subsidiary of Power Resources, Inc.,

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 where
the Company currently has ISR mining projects. URI also has 183,000
acres of uranium mineral holdings and 101.4 million pounds of in-place
mineralized uranium material in New Mexico and a NRC license to produce
up to 1 million pounds of uranium per year. The Company has digitized
over 18,800 drill logs representing nearly 23 million feet of hole
drilled with an estimated replacement cost of $700 million. The Company
acquired these properties over the past 20 years along with an extensive
information database of historic mining logs and analysis. None of URI′s
properties is currently in production.

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

Uranium Resources routinely posts news and other information about the
Company on its Web site at www.uraniumresources.com.
