Uranium Resources Granted 180-Day Extension by NASDAQ to Regain Compliance with Bid Price Rule

Uranium Resources, Inc. (NASDAQ: URRE) ('URI? or the 'Company?),
announced that on July 17, 2012, it received notification from NASDAQ
granting an additional 180-day period, or until January 14, 2013, to
regain compliance with NASDAQ′s minimum $1.00 bid price per share rule.
Under NASDAQ listing rules, the Company was granted this extension
because it met the continued listing requirement for market value of
publicly held shares and all other applicable NASDAQ listing
requirements, except the bid price requirement, and the Company provided
written notice to NASDAQ of its intention to cure the bid price
deficiency during the second compliance period.

The Company will regain compliance with the minimum bid requirement if
at any time prior to January 14, 2013, the bid price for the Company's
common stock closes at $1.00 per share or above for a minimum of 10
consecutive business days.

If the Company does not regain compliance by the end of this second
grace period, it will receive notification from NASDAQ that its shares
are subject to delisting. At that point the Company may then appeal the
delisting determination to a Hearings Panel.

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.

Uranium Resources routinely posts news and other information about the
Company on its website at www.uraniumresources.com.
