CENTENNIAL, Colo., February 13, 2017 – Uranium Resources, Inc. (Nasdaq: URRE; ASX: URI), an energy metals exploration and development company, announced today its preliminary unaudited fiscal year end operating results for 2016 and key business highlights for 2016 and to date.

Christopher M. Jones, President and Chief Executive Officer, said, “We continue to make our business leaner and lower cost, while simultaneously developing a new lithium business and maintaining our optionality on the future rising uranium price.  As we enter 2017 with substantial cash in our treasury, we are in a strong financial position to fund our business operations going forward.  We are not just waiting for change, we are making change.”

The Company first announced that it had initiated a lithium exploration and development business on August 24, 2016.

·

Uranium operations.  In 2016 the Company continued to maintain its uranium properties on standby, awaiting improved uranium market prices.  Activities included continued restoration/reclamation activities in South Texas, while in New Mexico, the Company is currently in negotiations for extensions on the Cebolleta and Juan Tafoya leases.  The Company’s Temrezli property in Turkey is also being maintained on standby.

Laramide asset sale. On January 5, 2017, the Company closed the sale of its Crownpoint and Churchrock properties in New Mexico to Laramide Resources Ltd.
