LEWISVILLE, Texas -- January 7, 2013

Uranium Resources, Inc. (NASDAQ: URRE) (URI) today announced the expansion and
extension of its South Texas exploration agreement with Cameco Texas, Inc.
(Cameco), a subsidiary of Power Resources, Inc., which is a subsidiary of
Cameco Corporation (NYSE: CCJ). Additionally, the Company signed an amendment
to its uranium mining lease option in Kenedy County, Texas for the Tecolote
tract, approximately 22,700 net acres that will be a part of the exploration

“The amendment of our exploration joint venture into Tecolote is significant
for many reasons,” stated Terence J. Cryan, Interim President and CEO of URI.
“Cameco’s commitment to a 70% interest in the program with the addition of the
new property underlies our belief of its stronger potential and our commitment
to developing uranium in South Texas. We remain encouraged by the
opportunities in the area and believe Tecolote will provide us a platform to
grow our assets in South Texas and capitalize on our two processing plants in
the region.”

Under the terms of the amended exploration agreement, both parties have agreed
to extend the exploration agreement to a five-phase, five-year exploration
program to include Tecolote. Cameco has committed $4.3 million to increase its
interest to 70% in the expanded program. Cameco will fund and be the
exploration operator for Phase III.

In addition to adding the 22,700 acres of Tecolote, the lease option amendment
extended the original lease to 60 months with the election date to lease the
acreage for production now being November 30, 2015. It requires a minimum
exploration obligation of $1.0 million, or 100 exploration wells during Phase
III. Phase IV and Phase V require $1.5 million, or 150 exploration wells, and
$2.0 million, or 200 exploration wells, respectively. Investment or drilling
in excess of the minimum requirement in any year counts toward the following
year’s requirements.

Tecolote is located within the prolific South Texas uranium district which has
been a major producer of uranium for half a century. Situated near uranium
mining operations which produce from the Goliad Formation, the property also
hosts several oil and gas fields and is bisected by a major depositional
channel system. These provide the geologic, stratigraphic, and geochemical
components for uranium deposition and water-saturated host sand with good rock

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

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.
