Uranium Resources Announces Director Changes

Uranium Resources, Inc. (NASDAQ: URRE) ('URI? or the 'Company?),
announced that John H. Pfahl was elected as a director of URI at its
annual meeting held on June 4, 2012, succeeding Leland O. (Lee) Erdahl,
who did not seek reelection after 18 years of outstanding service to the
Company.

Paul K. Willmott, Executive Chairman of the Board of URI, commented,
'John′s extensive experience in all facets of the mining industry will
prove an invaluable asset to URI. Part of our strategy has been and will
continue to be evaluating opportunities to grow our asset base in New
Mexico and Texas. We believe his experience in commercial due diligence,
finance negotiations and mergers and acquisitions will make John an
integral member of the URI team.?

Mr. Pfahl has technical and commercial experience in the mining sector
across a diversified range of mineral commodities and geographic
regions. He is an Associate with Resource Capital Funds, an investment
adviser with approximately $1.9 billion in assets under management and
whose clients are mining-focused private equity funds. Mr. Pfahl has
managed and participated in active investments in companies with
projects ranging from late stage exploration through production.
Previously, he was a consultant in the environmental sector with
Newfields Boulder LLC. Mr. Pfahl holds a Bachelor of Science degree in
Engineering and a Master of Engineering (Master of Mines) degree from
the Colorado School of Mines.

Commenting on Lee Erdahl′s service, Mr. Willmott added, 'Lee has
provided invaluable leadership over the years and will be sorely missed.
Drawing on decades of experience in several different capacities
including CEO of a number of mining companies, Lee helped guide URI
through several market cycles. We wish Lee the very best and thank him
for his years of committed service to URI and our shareholders.?

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
also has 183,000 acres of uranium mineral holdings and 101.4 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. The
Company acquired these properties over the past 20 years along with an
extensive information database of historic drill hole logs, assay
certificates, maps and technical reports. None of URI′s properties is
currently in production.

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, 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.
