Uranium Resources Reports Enhanced

Financial Position in 1Q 2014 Financial Results

CENTENNIAL, Colo., May 8, 2014 — Uranium Resources, Inc. (NASDAQ: URRE) reports that it has significantly improved its working capital to $8.9 million at March 31, 2014 in its 1Q 2014 financial results.

Highlights for 1Q 2014 and to date:

·                  Operating and mineral property expenses decreased by 21% from $1.1 million in 1Q 2013 to $0.9 million in 1Q 2014.

·                  Net cash used in operating activities was $3.8 million for the first quarter, essentially flat with 1Q 2013.

·                  During the first quarter, the Company successfully raised $11.3 million mostly from a registered direct offering and a smaller amount from its at-the-market sales agreement.

·                  The Company drew $2.0 million in February 2014 from the first tranche and a final $3.0 million from the second tranche of its senior convertible loan facility with its largest shareholder Resource Capital Fund V L.P. (RCF) on April 30, 2014. The Company and RCF agreed to cancel the remaining undrawn amount under the convertible loan.

·                  The Company completed a Technical Report on the Cebolleta Project in New Mexico in February 2014, well ahead of schedule.

Christopher M. Jones, President and Chief Executive Officer, said, “We continue to trend down on our cash burn rate in operating and mineral property expenses and ongoing general and administrative expenditures. General and administrative costs were $2.6 million in 1Q 2014, level with 1Q 2013, despite higher legal, accounting and public company expenses than the year ago quarter due to the one-time expenses related with the January special meeting for shareholders to approve the convertible loan facility. Our successful stock offering in February coupled with our decision to draw $3.0 million under the convertible loan facility positions our Company to be funded well into 2015.”

Financial Overview

The first quarter net loss of $3.5 million was 23% lower than in 1Q 2013 while net loss per share was $0.15 in 1Q 2014 compared with $0.26 in 1Q 2013. Cash and equivalents were $10.6 million at March 31, 2014 compared with $1.1 million at December 31, 2013 and $4.4 million at March 31, 2013. On May 6, 2014, the cash balance was $11.9 million and shares outstanding totaled approximately 24.7 million.

On April 29, 2014, the Company and RCF amended the convertible loan agreement to reduce the size of the second tranche to $3.0 million from $5.0 million and to cancel the third and final tranche of another $5.0 million, as described in the Company’s Form 8-K filed on April 30, 2014. With the receipt of $3.0 million from the second tranche of the convertible loan, URRE is now carrying a total of $8.0 million under the convertible loan.

Table 1: Financial & Capital Summary

(1)         The current convertible loan totals $8.0 million at May 6, 2014 as a result of the Company having drawn $3.0 million subsequent to the end of 1Q 2014. The convertible loan facility is recorded under long-term liabilities on the Company’s balance sheet at March 31, 2014 as a derivative liability at a fair value of $3.1 million and convertible loan’s residual value of $1.7 million.

On January 29, 2014, the Company’s shareholders overwhelmingly approved the senior secured convertible loan facility with RCF and the issuance of shares of URRE common stock related to the convertible loan.

All data shown for the periods prior to 4Q 2013 were restated. In 4Q 2013, the Company filed a restatement of its historical financial results to expense certain costs that were previously capitalized for the years ended December 31, 2010, 2011 and 2012 and the quarters therein and for the three quarters ended September 30, 2013. The restatement did not impact the Company’s cash position, financing agreements or progress on operating plans.

Operations Overview

Restoration of the Kingsville Dome ponds in South Texas was completed in January 2014. Total expenditures were approximately $4.6 million, of which $2.3 million was spent in 2013 and $237,000 in final expenses were recorded in 1Q 2014. The completion of this project is expected to significantly reduce URRE’s operating expenses for 2014.

Well stabilization work and monitoring activities continue at the Kingsville Dome and Rosita facilities in South Texas, which are on stand-by and may be restarted by the Company when there is a sustained recovery in uranium prices.

Technical Reports

The Company completed a Technical Report on mineral resources at the Cebolleta Project consistent with Canadian Institute of Mining, Metallurgy and Petroleum Standards for reporting mineral resources, which are internationally accepted, and was prepared according to the standards of Canadian Nation Instrument 43-101, as reported in the Company’s April 10, 2014 news release. The Cebolleta NI 43-101 Technical Report, which is available on the Company’s website, recommends the Company advance the Cebolleta Project to a Preliminary Economic Assessment.

The Company is evaluating the Technical Report recommendations for the Cebolleta Project and will make a decision on additional drilling and work for the Preliminary Economic Assessment in conjunction with the Technical Report results for the Churchrock, Juan Tafoya and Roca Honda projects in New Mexico. These three Technical Reports are expected throughout 2014.

Uranium Market Commentary

According to UxC Consulting, the uranium spot price broke below $35.00 per pound in early March 2014 and has been trending downward to $34.00 per pound at the end of March 2014 and retracing to the 2005 price level of about $29.00 currently. Uranium like other commodities remains volatile. The Company believes that overall uranium fundamentals have not changed and expects tightening supply and expected rising demand from expanding global nuclear power generation to bring about recovering uranium prices over the mid-term.

2014 Outlook

The Company continues to monitor the uranium market closely, balancing expected readiness to fast track resumption of production, subject to improved uranium prices and project financing, with cash conservation, and adjusting project priorities.

During 2014, the Company expects to:

·                  Generate NI 43-101 compliant technical reports for the Juan  Tafoya and Roca Honda projects by mid-2014 and the Churchrock project by the end of 2014,

·                  Evaluate and prioritize other projects for NI 43-101 compliant technical reports,

·                  Reduce and maintain cash burn rate to under $1.0 million per month,

·                  Make meaningful progress with the Navajo Nation Council subcommittee in advancing the Churchrock ISR project, and

·                  Pursue additions of quality reserves within an economic haulage distance for processing at the Company’s two facilities in South Texas, as well as opportunistic, value-accretive acquisitions and/or operating/processing agreements.
