Uranium Resources, Inc.

("URI" or the "Company") today provided an update on the Company's activities and financials through June 30, 2013, as well as its strategy and outlook. Second Quarter and Recent Highlights Consolidated corporate headquarters in Denver, Colorado, and rationalized office locations which should generate $1.5 million in annualized savings. Strengthened team with the appointment of Jeffrey L. Vigil as Vice President-Finance and Chief Financial Officer. Improved economics from future production in Texas with renegotiated uranium supply contract. URI continues to actively monitor all expenses and is executing initiatives to conserve cash; the Company expects a lower monthly cash burn during the second half of the year. "We continue to take the necessary actions to conserve cash and strengthen our balance sheet in the near term and to place us on solid ground for the future. During the quarter, we executed our consolidation plan and enhanced the corporate team based in Denver with the appointment of Jeff Vigil as CFO," stated Christopher M. Jones, President and Chief Executive Officer of URI. "The recently announced renegotiated ITOCHU agreement and the progress made at the Kingsville Dome pond project are important steps that will position us to resume production activities in Texas during the latter half of 2014." Preparing for return to production in Texas; Restoration and rehabilitation activities progressing Groundwater restoration activities in Texas continue to progress, with well plugging of the Rosita project's production areas 1 and 2 by the end of the year. The Company continues restoration activities with stabilization targeted for the fourth quarter of 2013 for all production areas at the Kingsville Dome and Vasquez projects. The Kingsville Dome holding pond rehabilitation is expected to be completed by the end of the year, and the refurbishment of the processing facility back to production capability will take approximately six months thereafter. The Company expects to be in a position for production in Texas during the latter half of 2014. URI amended its uranium supply contract with ITOCHU International Inc. in early July. The new contract strengthens the economics of production from URI's facilities by providing an improved sales pricing structure. ITOCHU committed to purchase one-half of all production from the Vasquez, Rosita or Kingsville properties up to three million pounds of U3O8. In early January 2013, URI announced the expansion of its exploration program with Cameco to include 22,700 net acres known as the Tecolote tract. URI and Cameco are currently in phase three of a five-phase exploration program. This phase is expected to wrap up by the end of 2013 and to date, seven wide-spaced holes at an average depth of about 1,200 feet have been completed. A second drill rig was recently brought onto the property. Evaluating long-term assets in New Mexico URI recently initiated evaluation work in an effort to produce national instrument 43-101 reports for some of its long-term assets in New Mexico, including Roca Honda and the Cebolleta property. The Company believes that this additional technical analysis will provide management with greater strategic clarity. URI has continued its efforts on reaching a permanent access agreement with the Navajo Nation. Conversations continue and recently environmental and surveying contractors were on the site and completed some initial work on a proposed right of way. These actions are aimed at further de-risking and improving the economics of the Churchrock project. Liquidity Position Cash at June 30, 2013 was $5.3 million compared with $4.4 million at the end of the first quarter of 2013 and $4.7 million as of December 31, 2012. The June balance reflected the return of capital as a result of replacing $9.0 million of fully collateralized financial surety instruments with new surety bonds requiring collateral of only 40% of the face amount of the bonds, resulting in approximately $5.4 million in additional cash available for operations. At the end of July 2013, URI's cash position was $4.25 million. Mr. Jones stated, "We have lowered our core cash requirements now that we have completed many of our efficiency and consolidation initiatives and expect to see further cost reductions as restoration activities come to a close around the end of the year." URI did not utilize its existing At-The-Market Sales Agreement ("ATM") during the second quarter of 2013. At the end of the quarter, the Company had a total of $9.0 million in share value available for future sales under the ATM.
