Uranium Resources, Inc. Announces Commencement of Development at South Texas
Projects

    LEWISVILLE, Texas--(BUSINESS WIRE)--Dec. 5, 2005--Uranium Resources, Inc.
(OTCBB:URIX) announced today that the Texas State Office of
Administrative Hearings has issued its Proposal for Decision
recommending that the Texas Commission on Environmental Quality
("TCEQ") approve the Company's Production Area Authorization 3 at the
Kingsville Dome project, subject to certain conditions that the
Company believes it can satisfy. The Company anticipates that the TCEQ
should act on this recommendation in January 2006.
    The Company started wellfield development at previously approved
production areas at Kingsville Dome in November 2005 and expects that
production should commence in the second quarter of 2006. Activities
have also begun to upgrade the Kingsville processing facility to allow
the processing of this additional Kingsville Dome production and
production from PAA 3, which the Company projects will start later in
2006.
    Paul K. Willmott, President and Chairman, stated, "We have
produced over 3.5 million pounds of uranium from Kingsville Dome in
the past and eagerly welcome our ability to once again access the
potential of this resource base. We expect to have the ability to
produce from both our Vasquez and our Kingsville Dome sites
concurrently. This should strengthen our position as a stable and
reliable supplier of uranium in a market that continues to show
firming prices in both the short and long-term. We will continue to
evaluate our uranium sales contract position and look to add value to
the Company by enhancing the value of our contract portfolio."
    The Company also announced that it has commenced exploration
drilling on the recently acquired 750 acres near the Company's
currently idle but fully licensed Rosita facility. The Company plans
to upgrade and restart the Rosita facility to process any economic
material found along with the recently identified mineralized uranium
material on the Rosita property itself.
