 Uranium Resources, Inc. Announces Updated Production and Operations
                   Status for South Texas Projects


    LEWISVILLE, Texas--(BUSINESS WIRE)--Sept. 19, 2006--Uranium
Resources, Inc. ("URI") (OTCBB:URRE) announced production and
operations updates for its South Texas uranium projects.
    In July, URI stated its South Texas production was being adversely
affected by a shortage of drill rigs, permitting delays, and weather
related problems. We indicated these problems could continue through
July and expected production to increase beginning in August. However,
these problems have continued through August and into September; and
the loss of key personnel to competitors has added to our problems. As
a result, we will not meet our July forecast of 670,000 pounds of
production for 2006.
    Delays in restarting production at Kingsville Dome and Rosita have
continued. Kingsville was restarted in April 2006. We planned to bring
on three new wellfields, one in August and two in September. Weather
problems and a shortage of available drill rigs and logging trucks
have pushed off the expected startup of these wellfields by at least
one month. At Rosita, the shortage of drill rigs and logging trucks
has delayed estimated production until the first quarter of 2007. The
shortage of drill rigs and logging trucks is the result of intense
industry-wide competition for exploration and development tools.
    In addition to the delays in restarting Kingsville and Rosita,
Vasquez has continued to operate below expectations. At the beginning
of the project in 2004, our mining plan indicated we could produce the
Vasquez property at an annual rate of 700,000 pounds. The geological
and chemical problems we experienced in 2005 caused us to revise that
estimate downward to an annual capacity of 400,000 pounds. This
estimate assumed steps we implemented would successfully resolve
production problems we had never experienced at our other mines. While
partially successful, these steps have still not led to higher
production levels.
    We are now evaluating the extent and scope of our future
development efforts at Vasquez. Such evaluation involves weighing the
economic impact of continuing development at Vasquez at current levels
compared to the benefits that could be derived if all or a portion of
our resources (drill rigs, logging trucks, and personnel) are
redeployed from Vasquez to Kingsville Dome and Rosita in order to
bring these properties up to full production sooner.
    Given the above factors, production has proven difficult to
forecast with any accuracy despite our best efforts to do so.
Therefore, we have concluded that we will no longer forecast our
production or production costs for 2006 or any future year, and we
withdraw all previous forecasts. We will report our ongoing
development efforts for each of our properties as we have something
concrete to report, such as the obtaining of mining permits and the
commencement of production. We will report our actual production for
each month.
    In July and August, we produced 42,000 pounds, bringing total
production for the first eight months of 2006 to 156,000 pounds.
