Exhibit 99.1


         Uranium Resources, Inc. Clarifies Form 424B3 Filing,

    --  "Re-Offer Prospectus" Not an Intent to Sell

    --  Required Update for Employee and Director Benefit Plans

    Metal/Mining Writers/Business Editors

    LEWISVILLE, Texas--(BUSINESS WIRE)--May 16, 2007--Uranium
Resources, Inc. (NASDAQ: URRE) ("URI"), a uranium exploration,
development and mining company, provided clarification regarding its
Form 424B3 entitled RE-OFFER PROSPECTUS filed on May 15, 2007. The
filing was NOT an arrangement for a "secondary offering" for the
employees and directors, NOR was it an indication that the officers
and directors of URI intend to sell their stock.

    The purpose of the filing was to update the Form S-8 Registration
Statement filed May 17, 2006 which registered shares of the Company's
Common Stock which may be issued from time to time to participants of
the Company's 2004 Stock Incentive Plan, as well as other plans that
date back to 1995.

    The filing, as required by The Securities and Exchange Act of
1933, fully discloses to investors that the listed participants of the
benefit plans do have the right to sell shares they acquired over time
pursuant to these benefit plans. In the filing, the Maximum Number of
Shares to be Offered provided is, in fact, the total number of shares
each individual owns as a result of shares and/or options issued
pursuant to the subject benefit plans. The "residual holdings"
identified for the individuals after an "assumed" sale represent the
shares the particular individual owns as a result of open market
purchases which are not related to options issued under the benefit
plans.
