Energy Fuels Inc. and Denison Mines Corp. Announce Transaction to Create Leading U.S. Uranium Company

Energy Fuels Inc. ("Energy Fuels" or "EFR") (TSX: EFR.TO - News) and Denison Mines Corp. ("Denison" or "DML") (TSX: DML.TO - News)(AMEX: DNN - News) today announced that they have entered into a Letter Agreement to complete a transaction (the "Transaction") whereby EFR will acquire all of Denison's mining assets and operations located in the United States (the "US Mining Division") from Denison in exchange for 425,441,494 common shares of EFR (the "EFR Share Consideration"). Immediately following the closing of the Transaction, Denison will complete a Plan of Arrangement (the "Denison Arrangement") whereby Denison will complete a reorganization of its capital and will distribute the EFR Share Consideration to DML shareholders on a pro rata basis as a return of capital in the course of that reorganization.

Upon completion of the Denison Arrangement, Denison shareholders will receive approximately 1.106 common shares of EFR for each common share of DML owned and will in aggregate own approximately 66.5% of the issued and outstanding common shares of EFR.

Energy Fuels and Denison believe that the Transaction and the Denison Arrangement will provide a number of substantial benefits for shareholders of both companies, including the following:

 

--  Creation of the largest 100% U.S. pure-play uranium producer and one of
    the largest holders of National Instrument 43-101("NI 43-101") compliant
    U.S. based uranium resources.
    --  2012 production forecasts totaling greater than 25% of total U.S.
        estimated production.
    --  Measured and Indicated Resources of 49.8 million lbs of U3O8, plus
        Inferred Resources of 17.9 million lbs of U3O8.
--  U.S. focus provides compelling fundamentals: domestic consumption of 55
    million lbs of U3O8 per year vs. domestic production of only 4 million
    lbs of U3O8 per year.
--  Clear operational synergies and capital efficiencies to increase
    production.
--  Combination of mining and development assets which will accelerate the
    rate of development of EFR mines, provide higher throughput of mill
    feed, and extend the number of years of production at the White Mesa
    Mill.
--  EFR's Sheep Mountain Project is an advanced-stage development asset
    which provides flexibility to bring an additional 1.5 million lbs per
    year of U.S.-produced U3O8 on-line.
--  Creation of a strategic platform for continued uranium consolidation
    within the U.S.
--  Substantial vanadium by-product from the White Mesa Mill and Colorado
    Plateau Properties, where historic uranium to vanadium ratios have
    averaged approximately 5:1.
--  Combined management expertise, with decades of combined uranium mining
    and processing experience.
--  DML shareholders to benefit from the division of two distinctly
    different business profiles as well as exclusive management focus on
    exploration and development, such as DML's high-profile Wheeler River
    project in the Athabasca Basin region of northern Saskatchewan and its
    Mutanga project in Zambia.

Steve Antony, President and CEO of Energy Fuels commented, "This transaction is transformational for Energy Fuels and reshapes the landscape of the uranium sector within the U.S. It combines the highly strategic asset of the only operating uranium mill in the U.S., White Mesa, with a significant resource base that substantially increases White Mesa's available feedstock. The result is an unmatched production growth profile and the opportunity for both Energy Fuels and Denison shareholders to benefit from the clear operational synergies that result from this transaction. I look forward to working with Denison's U.S. team to maximize the benefits of this important combination."

Ron Hochstein, President and CEO of Denison added, "This transaction is an important step forward for Denison. The Company has evolved on two parallel but different tracks, being both an exploration and development entity with a global footprint and an established producer in the United States. We are pleased to have the opportunity to combine our U.S. operations with such a complimentary set of assets and people. I'm excited about the opportunities that lie ahead for both Denison and Energy Fuels shareholders and believe that this transaction only serves to strengthen the operations of both companies."

Overview of EFR and Denison's U.S. Mining Division

Energy Fuels Inc.

Energy Fuels Inc. is a uranium and vanadium mineral development company. The Company recently acquired Titan Uranium Inc., including the Sheep Mountain Project in the Crooks Gap District of Wyoming. The Company also received a Final Radioactive Materials License from the State of Colorado for the proposed Pinon Ridge Uranium and Vanadium Mill in March 2011. The mill will be the first uranium mill constructed in the United States in over 30 years.

With about 61,000 acres of highly prospective uranium and vanadium properties located in the states of Colorado, Utah, Arizona, Wyoming, and New Mexico, as well as exploration properties in Saskatchewan's Athabasca Basin totaling approximately 32,000 additional acres, the Company has a full pipeline of additional development prospects. Energy Fuels, through its wholly-owned subsidiaries, has assembled this property portfolio along with a first class management team, including highly skilled technical mining and milling professionals.

On March 1, 2012, Energy Fuels announced an updated Preliminary Feasibility Study for Sheep Mountain. The study contemplates the concurrent development of the underground and open pit deposits for a 15 year mine life. This option generates a pre-tax Internal Rate of Return (IRR) of 42% and a Net Present Value (NPV) of US$201 million, at a 7% discount rate and a $65/lb long term U3O8 price. This option has an expected initial CAPEX requirement of US$109 million and OPEX of US$32.31 per lb. recovered. The Sheep Mountain project is currently at an advanced stage of permitting. Production is expected to commence in 2015, with a peak production rate of 1.5 million lbs U3O8 per year.

The Sheep Mountain Project contains an Indicated Resource of 12,895,000 tons at an average grade of 0.12% eU3O8 (30,285,000 lbs eU3O8). This figure includes Probable Reserves of 7,453,000 tons at an average grade of 0.123% eU3O8 (18,365,000 lbs eU3O8). Energy Fuels' Colorado Plateau properties additionally contain Measured & Indicated Resources of 1,951,486 tons at an average grade of 0.24% eU3O8 and 0.89% V2O5 (9,371,821 lbs eU3O8 and 34,862,116 lbs V2O5).

The technical information in this news release regarding the Sheep Mountain Project was prepared in accordance with the Canadian regulatory requirements set out in NI 43-101 and is extracted from Preliminary Feasibility Study for Sheep Mountain dated April 13, 2012 which is filed on EFR's SEDAR profile and is available for viewing at www.sedar.com.

Denison's U.S. Mining Division

All of Denison's U.S. assets are held directly or indirectly through its wholly-owned subsidiary Denison Mines Holdings Corp. ("DMH"). DMH holds its uranium mining and milling assets through subsidiaries, as follows:

 

--  the White Mesa Mill, a 2,000-ton per day uranium and vanadium processing
    plant near Blanding, Utah through Denison White Mesa LLC;
--  the Colorado Plateau mines, straddling the Colorado and Utah border,
    through Denison Colorado Plateau LLC;
--  the Daneros uranium mine in the White Canyon district of southeastern
    Utah, and other exploration properties through Utah Energy Corporation;
--  the Arizona Strip properties through Denison Arizona Strip LLC;
--  the Henry Mountains uranium complex in southern Utah and other
    exploration properties through Denison Henry Mountains LLC; and
--  miscellaneous properties through Denison Properties LLC.

All of the U.S. properties are operated by Denison Mines (USA) Corp., a wholly-owned subsidiary of DMH.

Denison's White Mesa Mill in Utah is the only conventional uranium mill currently operating in the U.S. It is fully licensed and permitted to process 2,000 tons per day, producing up to 8 million lbs of uranium per year. A vanadium co-product recovery circuit allows for the processing of vanadium ore within the Colorado Plateau mines and its central location allows for hauling of uranium ore from Arizona, Utah, Colorado, and New Mexico.

The Arizona Strip has higher grade production from breccia pipes. The Arizona 1 mine is currently producing with a track-record of resource replacement. A second mine (Pinenut) is expected to open in 2012. Shaft sinking is expected to begin at the Canyon mine in the fourth quarter 2012, pending regulatory approval, and the EZ1 & EZ2 properties are progressing through permitting.

The Henry Mountains Complex in Utah consists of the Bullfrog and Tony M deposits and represents Denison's largest resource in the U.S. (12.8 million lbs Indicated Resources, 8.1 million lbs Inferred Resources). Currently the complex is on care and maintenance. It was fully permitted in September 2007 and has excellent infrastructure, access, and is production ready. Haulage to the mill is along County and State highways.

The technical information in this news release regarding the Henry Mountains Complex was prepared in accordance with the Canadian regulatory requirements set out in NI 43-101 and is extracted from the technical reports prepared for DML titled "Technical Report on the Tony M-Southwest Deposit, Henry Mountains Complex, Utah, USA" dated March 19, 2009, and "Technical Report on the Henry Mountains Complex Uranium Project, Utah, U.S.A." dated October 17, 2006, which are filed on Denison's SEDAR profile and are available for viewing at www.sedar.com.
