Uranium Resources Provides Update on South Texas Exploration Program

Uranium Resources Provides Update on South Texas Exploration Program

Cameco and URI Ending Current Joint Venture

CENTENNIAL, Colo., Dec. 5, 2013 (GLOBE NEWSWIRE) -- Uranium Resources, Inc.
(Nasdaq:URRE) ("URI" or the "Company") today announced that Cameco (NYSE:CCJ)
has elected to discontinue the joint venture exploration agreement in Kenedy
County, Texas. This exploration agreement was first announced in May 2011 and
was most recently expanded and extended in December 2012.

Christopher M. Jones, President and Chief Executive Officer of URI, commented,
"This was a greenfield exploration site that to date has not generated
significant finds. Given the current economics of exploration, we certainly
understand Cameco's decision to focus its resources on more developed
projects. We remain committed to developing uranium in South Texas as we aim
to leverage our two processing plants in the region."

With the termination of the agreement, Cameco retains no interest in URI's
business activities.
