Uranium Resources Announces New NI 43-101 Compliant Technical Report for Cebolleta Project

Uranium Resources Inc. (NASDAQ: URRE) announced the completion of a new Technical Report on the mineral resources at its Cebolleta Project in New Mexico. Based on the quantity and quality of the in-place, non-reserve inferred mineralized material of 5.6 million short tons at an average uranium grade of 0.17%, the report recommends that the Company advance the Cebolleta Project to a Preliminary Economic Assessment or scoping level study.

The Cebolleta Project’s Technical Report adheres to the Canadian Institute of Mining, Metallurgy and Petroleum Standards (Canadian Standards) for reporting mineral resources and reserves, which are internationally accepted, and has been prepared according to the standards of Canadian National Instrument 43-101 (NI 43-101). The report is available on the Company’s website: www.uraniumresources.com, under Projects/ New Mexico/ Cebolleta.

Christopher M. Jones, President and Chief Executive Officer of URRE said, “We are excited about the findings of this Cebolleta Technical Report and believe that this advances the project towards the next stage of a Preliminary Economic Assessment.”

Mr. Jones continued, “We achieved a major milestone for our Company by completing the Cebolleta Technical Report about eight weeks ahead of schedule. In addition, we now expect to issue a total of four Technical Reports on our New Mexico projects in 2014, one more than our previous goal of three reports, with the addition of the Juan Tafoya Project Technical Report due to be completed in June 2014. We expect to deliver on reports for Roca Honda around mid-year 2014 and Churchrock by the end of 2014. Our corporate geological team is making meaningful progress with the external, independent Qualified Persons in preparing the Technical Reports, all of which will be prepared consistent with NI 43-101 standards.”

Located in Cibola County, approximately 45 miles northwest of Albuquerque, New Mexico, the Cebolleta Project is wholly controlled by URRE and sequenced in the Company’s long-term path to production planning and is the Company’s third largest uranium project behind the Churchrock and Nose Rock projects in terms of tons of material. The non-reserve mineralized material for Cebolleta shown in Table 1 below was classified as “Inferred Resources” according to the Canadian Standards and best practice guidelines for estimation of mineral resources. Investors are cautioned that the requirements and terminology of NI 43-101 and the Canadian Standards differ significantly from the requirements and terminology of the SEC set forth in the SEC’s Industry Guide 7, and that inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category. See “Cautionary Note Regarding References to Resources and Reserves” below.

The Cebolleta Project covers approximately 6,700 acres of leased privately-owned mineral and surface rights near the eastern end of the prolific Grants Mineral Belt, which is one of the largest known concentrations of sandstone-hosted uranium deposits in the world. Within the project area there are several uranium deposits located in the Jackpile sandstone unit of the Jurassic-age Morrison Formation, which hosts several of the uranium deposits of the Grants Mineral Belt. The Cebolleta property is the site of the historic L-Bar uranium mine and mill of Sohio Western Mining and the adjoining St. Anthony uranium mine of United Nuclear Corporation.

The estimate on non-reserve inferred mineralized material at the project was based upon more than 600 conventional rotary and core drill holes generally completed on spacings of 100 to 200 feet. The Cebolleta Technical Report recommended going forward with “confirmation drilling” with the objective of raising the confidence levels of a significant portion of the mineralized material to the “Indicated Resources” category. Another recommendation in the Technical Report was to drill and develop an initial resource model and estimate for the historic St. Anthony mine area. Deposit block models were constructed to achieve three dimensional representations of the distribution of uranium grades, as well as three dimensional distributions of the geology controlling the mineralized zones. Block grades were determined using an inverse distance power of two method.

The inferred mineral resources were lower than the Company’s legacy mineral estimate reported in the Company’s recent Form 10-K for 2013 as 6.7 million tons at an average uranium grade of 0.18%, due to the more conservative parameters applied in this new Technical Report, including capping the uranium grade and using minimum thickness criteria.

The Cebolleta Technical Report estimated that the drilling, modeling and initial metallurgical and geotechnical study for a Preliminary Economic Assessment over a nine-to-12 month period would cost approximately $1.7 million. URRE holds an Exploration Permit from the State of New Mexico for drilling at Cebolleta. The Company is evaluating the Technical Report recommendations and expects to make a decision on commencing any Preliminary Economic Assessment work by the end of 2014 in conjunction with the Technical Report results for Churchrock, Juan Tafoya and Roca Honda.

The Cebolleta Technical Report was prepared by Allan V. Moran of Tucson, Arizona and Frank A. Daviess of Golden, Colorado, both independent Qualified Persons as defined by NI 43-101. The report is available on the Company’s website: www.uraniumresources.com, under Projects/ New Mexico/ Cebolleta.

Qualified Persons

Dean T. “Ted” Wilton, CPG-7659, Chief Geologist and Vice President of Uranium Resources, is a Qualified Person under Canada National Instrument 43-101. Mr. Wilton supervised the preparation of the scientific and technical information regarding this project for this news release. In addition, the technical information regarding this project for this news release was also reviewed by Allan V. Moran, CPG-9565, of Tucson, Arizona and Frank A. Daviess, SME RM-0742250, of Golden, Colorado, both independent Qualified Persons as defined by NI 43-101, who prepared the NI 43-101 Technical Report on Resources for the Cebolleta Project. A description of the key assumptions, parameters and methods used to estimate the non-reserve mineralized material in inferred resources and data verification procedures and a discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, and other relevant factors, are contained in the Cebolleta Technical Report, which is available on the Company’s website.

Cautionary Note Regarding References to Resources and Reserves

Investors are cautioned that the requirements and terminology of NI 43-101 and the CIM Standards differ significantly from the requirements and terminology of the SEC set forth in the SEC’s Industry Guide 7 (“SEC Industry Guide 7”). Accordingly, the Company’s disclosures regarding mineralization may not be comparable to similar information disclosed by the Company in the reports it files with the SEC. Without limiting the foregoing, while the terms “mineral resources,” “inferred resources,” “indicated resources” and “measured mineral resources” are recognized and required by NI 43-101 and the CIM Standards, they are not recognized by the SEC and are not permitted to be used in documents filed with the SEC by companies subject to SEC Industry Guide 7. Mineral resources which are not mineral reserves do not have demonstrated economic viability, and investors are cautioned not to assume that all or any part of a mineral resource will ever be converted into reserves. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility study, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant “reserves” as in-place tonnage and grade without reference to unit amounts. In addition, the NI 43-101 and CIM Standards definition of a “reserve” differs from the definition in SEC Industry Guide 7. In SEC Industry Guide 7, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made, and a “final” or “bankable” feasibility study is required to report reserves, the three-year historical price (or in certain circumstances, a contract price) is used in any reserve or cash flow analysis of designated reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. The Company discloses non-reserve mineralized material that is considered too speculative geologically to be categorized as reserves under SEC Industry Guide 7. Estimates of non-reserve mineralized material are subject to further exploration and development, are subject to many risks and highly speculative, and may not be converted to future reserves of the Company. Investors are cautioned not to assume that all or any part of such non-reserve mineralized material exists, or is economically or legally extractable. Mineralized material that is not reserves does not have any demonstrated economic viability.
