Energy Fuels Inc. (TSX:EFR) and Strathmore Minerals Corp. (TSX:STM)(OTCQX:STHJF) are pleased to announce the signing of a Letter of Intent pursuant to which Energy Fuels and Strathmore have agreed to pursue a transaction whereby Energy Fuels would acquire, by way of a plan of arrangement, all of the issued and outstanding common shares of Strathmore. Under the terms of the LOI, Strathmore shareholders would receive 1.47 common shares of Energy Fuels for each common share of Strathmore held, resulting in the shareholders of Strathmore owning approximately 21% of the issued and outstanding shares of Energy Fuels upon completion of the Transaction. The consideration represents a premium of 31% based on the 20-day volume weighted average prices on the TSX as of May 22, 2013.
 

Energy Fuels and Strathmore believe the Transaction will position the newly combined Energy Fuels as the premier pure-play U.S. uranium company, supported by significant current uranium production of 1.175 million lbs. for its current fiscal year, as well as a robust pipeline of development projects. The U.S. remains the largest consumer of uranium globally, yet it is heavily reliant on imported uranium for over 90% of its supply requirements. Energy Fuels is well-positioned as a large, reliable source of uranium supply within the U.S., currently accounting for over 25% of estimated U.S. production.
 

Stephen Antony, President and CEO of Energy Fuels commented, “It is rare to find an acquisition that offers the magnitude of synergies that we believe exist between Energy Fuels and Strathmore. I am very excited about the merits of this transaction and the opportunity it represents for the shareholders of both companies. It is consistent with our corporate strategy and significantly strengthens the company’s long- term production profile throughout the Four Corners region of the southwest U.S. and in Wyoming. Strathmore is recognized for building a quality portfolio of U.S. uranium projects, and I look forward to working with them and their partners to realize the many synergies and to capitalize on the strengths that are created by this transaction.”
 

David Miller, Strathmore’s CEO continued, “We are excited to enter this transaction with Energy Fuels, which represents a strong fit with Strathmore’s asset base and a significant step forward in both the near- term and long-term development of our U.S. uranium portfolio. We evaluated this transaction extensively and believe the synergies between Energy Fuels and Strathmore are substantial. We look forward to the completion of this transaction which we expect will contribute to our shared goal of becoming the dominant uranium producer in the United States, and ultimately create significant value for our shareholders.”
 

Synergies
 

Energy Fuels and Strathmore believe the Transaction will result in significant value creation for the shareholders of both companies through numerous synergies.
 

Energy Fuels’ White Mesa Mill and Strathmore’s Roca Honda Project
 

Energy Fuels’ White Mesa Uranium Mill is the only operating uranium mill in the U.S., centrally-located to service the Four Corners region, which includes numerous uranium projects in Arizona, New Mexico, Colorado and Utah owned by Energy Fuels, Strathmore, and others. Strathmore’s advanced stage Roca Honda uranium project in New Mexico is one of the largest and highest-grade uranium projects in the U.S. with an NI 43-101 compliant resource estimate. The Roca Honda project is held in the Roca Honda Resources LLC Joint Venture, which is owned 60% by Strathmore and 40% by Sumitomo Corporation of Japan. The total resources for Roca Honda are summarized in the table shown below:

According to the August 6, 2012 technical report prepared in accordance with NI 43-101 entitled, “Technical Report on the Roca Honda Project, McKinley County, New Mexico, U.S.A.”, which also includes a Preliminary Economic Analysis, the base case evaluation shows attractive project economics, including a Net Present Value of US$220 million (using an 8% discount rate and $75/lb. uranium price), a nine year mine life, $24/lb. operating cost, and production of 2.6 million lbs. of U3O8 per year. In March 2013, the U.S. Forest Service published a draft Environmental Impact Statement on Roca Honda.
 

The recently completed RHR PEA assumed that a new uranium mill would be built in New Mexico to process uranium from Roca Honda. Given that Roca Honda is located within transport distance of the White Mesa Mill, Energy Fuels and Strathmore believe the Transaction will provide the option to process Roca Honda uranium at the White Mesa Mill rather than at a newly constructed mill. This could result in significant savings on development capital expenditures and reduce Roca Honda’s permitting timeline and cost. Based upon certain forecasts contained within the RHR PEA, as well as previous experience in conventional ore processing at the White Mesa Mill, Energy Fuels believes there is the potential for Roca Honda to be the largest, and one of the lowest cost, producing mines in the Energy Fuels asset portfolio.
 

Energy Fuels and Strathmore caution that the RHR PEA is preliminary in nature and includes inferred resources that are considered to be too speculative geologically for economic consideration that would enable them to be classified as mineral reserves. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that the RHR PEA will be realized.

Energy Fuels’ Sheep Mountain Project and Strathmore’s Contiguous Claims and Gas Hills Project
 

Energy Fuels’ Sheep Mountain uranium project is a large conventional uranium project in Wyoming which Energy Fuels is developing as a stand-alone production center. An April 13, 2012 technical report prepared in accordance with NI 43-101 entitled “Sheep Mountain Uranium Project, Fremont County, Wyoming, U.S.A., Updated Preliminary Feasibility Study” outlined improved economics for the project. Energy Fuels continues its permitting efforts on Sheep Mountain. Strathmore currently owns various mining claims that are contiguous with Sheep Mountain. By combining the claims, it is expected that the design of Sheep Mountain can be modified to take advantage of the additional area provided by the Contiguous Claims, thereby simplifying permitting and design and lowering Sheep Mountain’s development capital expenditures and ongoing operating expenses. The Sheep Mountain PFS estimates that the project has 12.9 million tons of Indicated Resource containing 30.2 million lbs. eU3O8 with an average grade of 0.12% eU3O8. Included in the above Sheep Mountain Indicated Resources are 7.4 million tons of Probable Mineral Reserves containing 18.4 million lbs. eU3O8 with an average grade of 0.123% eU3O8. The Sheep Mountain PFS also describes attractive project economics under three separate production scenarios, with Energy Fuels’ preferred scenario having a Net Present Value of $201 million (using a 7% discount rate and $65/lb. uranium price), $32.31/lb. operating cost, initial capital expenditures of $109 million, and a production rate of up to 1.5 million lbs. per year for 15 years.
 

Strathmore’s Gas Hills, Wyoming uranium project is located only 28 miles from Sheep Mountain. Gas Hills is currently being developed by Strathmore pursuant to a phased joint venture agreement with Korea Electric Power Company. According to a March 22, 2013 technical report prepared in accordance with NI 43-101entitled “Update of Gas Hills Uranium Project, Fremont and Natrona Counties, Wyoming, USA”, Strathmore showed a substantial increase in uranium resource estimates from the previous July 2012 report, including 2,300,000 tons of Indicated Resources containing 5,400,000 lbs. of eU3O8 with an average grade of 0.13% eU3O8. In addition, the technical report estimates that Gas Hills contains 3,900,000 tons of Inferred Resources containing 5,500,000 lbs. of eU3O8 with an average grade of 0.07% eU3O8. Under its joint venture agreement with Strathmore, KEPCO has the option to earn-in up to a 40% interest in Gas Hills by spending US$32 million over three years beginning in 2013. Energy Fuels and Strathmore believe that significant synergies exist between Sheep Mountain and Gas Hills which can be realized through combining the two projects including:

--  Evaluating opportunities that could result in significant savings on co-

    development capital expenditures by utilizing a common precipitation,

    filtering, drying and packaging plant circuit for uranium recovery from

    each project's heap leach process solutions;

--  Targeting a larger combined annual production profile in excess of the

    1.5 million pounds U3O8 currently outlined in the Sheep Mountain PFS;

--  Applying the Sheep Mountain permitting and design work to accelerate the

    Gas Hills development timeline;

--  Evaluating general and administrative expense savings in areas including

    payroll, purchasing, environmental compliance, engineering, surveying

    and geologists, land management and safety; and

--  Considering capital cost savings by utilizing common equipment fleets.

Finally, Strathmore’s Juniper Ridge uranium project in Wyoming is located approximately 92 miles from Sheep Mountain. Energy Fuels and Strathmore are currently evaluating the opportunity to potentially develop Juniper Ridge as part of a larger regional project with Sheep Mountain and/or Gas Hills.
