(URRE) Announces Amended Uranium Supply Contract

Agreement Paves the Way for Return to Production in Texas

LEWISVILLE, Texas, July 12, 2013 (GLOBE NEWSWIRE) — Uranium Resources, Inc. (Nasdaq:URRE) (URI) today announced that it amended its uranium supply contract with ITOCHU International Inc. effective July 11, 2013, to include a new sales pricing structure, new delivery dates and quantity levels.

Pursuant to the amended agreement, ITOCHU would purchase one-half of all production from URI’s Vasquez, Rosita or Kingsville properties up to three million pounds of U₃O₈. Any new production outside of those areas is not subject to the agreement. The purchase price will be based on published market prices at the time of delivery subject to a five percent discount when the market price is $56.50 per pound of U₃O₈ or less, or seven percent when greater than $56.50 per pound.

“Given the current dynamics in our industry, renegotiating our supply contract was an important step in our strategic plan to resume production activities in Texas,” stated Christopher M. Jones, President and CEO of URI. “This agreement improves the economics of production from our facilities and builds on our long-term relationship with ITOCHU by providing them access to a supply of uranium.”
