Uranium Resources, Inc. Announces Independent
Study Validates 91.7 million pounds of U ₃O ₈ on
New Mexico Properties

DALLAS, TX, Thursday, March 29, 2007 -— Uranium Resources, Inc. (OTCBB: URRE) (“URI”) announced today that an independent study by Behre Dolbear & Company (USA), Inc. has affirmed that six of the Company’s New Mexico properties hold 91.7 million pounds U₃O₈ that conform to the U.S. Securities and Exchange Commission’s (SEC) Guideline of non-reserve mineralized material.

This estimate reflects the Company’s ongoing reevaluation of its New Mexico properties, including its decision to consider development of certain properties by conventional mining and milling methods in addition to in-situ recovery methods. The properties reviewed were Mancos, Church Rock, Nose Rock, West Largo, Roca Honda and Crownpoint and are comprised of fee-owned minerals that were purchased from the Santa Fe Pacific Gold Corporation in 1997, unpatented lode mining claims and a mineral lease. The estimate for each property is based on studies and geologic reports prepared by prior owners, along with studies and reports prepared by geologists engaged by the Company. The estimates were reviewed and affirmed to the Company by Behre Dolbear & Company (USA), an independent private consulting firm.

Behre Dolbear can, as an expert witness, state to the Engineering section of the SEC the following:

1.	Major, reputable mining companies proved up the presence of uranium mineralization on the properties in the 1970s and 1980s,
2.	Development work, including drilling and shaft sinking, to mine the uranium was undertaken, but was halted by poor market conditions,
3.	The estimates of reserves and non-reserve mineralized material reviewed were prepared by qualified uranium specialists, and
4.	Behre Dolbear confirms that the methodology used by these experts to develop their estimates was appropriate and in accord with industry standards.

Dave Clark, President of Uranium Resources, Inc., commented, “This report confirms we already have the resource base we need to become a major producer in New Mexico. In addition, we are confident we can add significantly more resources by continuing to mine our extensive database and through exploration drilling on the many promising targets we have on our 183,000 acre land position in the Grants mineral belt. We feel we are well on our way to building a 200-300 million pound U₃O₈ resource base by developing our own properties and through acquisition, which supports our goal of becoming a 10 million pound per year producer by 2014.”

The Company will file the report in its entirety with the SEC on Form 8-K.
