ITEM 1.01         Entry into a Material Definitive Agreement

         On October 12, 2007, HRI-RAML Acquisition LLC, a Delaware limited
liability company (the "Buyer") and an indirect wholly-owned subsidiary of
Uranium Resources, Inc. (the "Company"), entered into a Membership Interest
Purchase Agreement (the "Purchase Agreement") with Billiton Investment 15 B.V.,
a Netherlands corporation (the "Seller") and owner of all the outstanding
membership interests in Rio Algom Mining LLC, a Delaware limited liability
company ("RAML"), pursuant to which the Purchaser has agreed to acquire all of
the outstanding membership interests in RAML (the "Transaction").

         The Buyer will pay to Seller $110,000,000 cash at closing, subject to
certain closing adjustments. In addition, Buyer has agreed to create a trust to
fund certain existing environmental remediation obligations, and an escrow to
fund certain existing pension and other health care obligations of RAML. The
total amount of the trust and escrow will not exceed $35,000,000. The closing is
anticipated to occur on or before June 1, 2008.

         The Purchase Agreement contains customary representations, warranties
and covenants by the Buyer and Seller. Consummation of the Transaction is
subject to certain conditions including receipt of necessary approvals from the
Nuclear Regulatory Commission (the "NRC") and compliance with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. In addition,
Buyer's obligation to consummate the Transaction is subject to the condition
that the Company has raised capital sufficient to pay the purchase price, fund
the remediation trust and escrow and provide adequate working capital for
operations.

         Buyer will owe a contingent payment of $16.5 million in the event that
RAML obtains an amendment to its existing NRC radioactive materials license for
the Ambrosia Lake mill site or a new license that allows RAML to construct and
operate a conventional acid leach-SX uranium mill facility and associated
tailings at Ambrosia Lake.
