Energy Fuels Inc. (TSX-EFR) (“Energy Fuels”) is pleased to announce the closing of its previously announced transaction whereby Energy Fuels will acquire all of the shares of the subsidiaries holding Denison Mines Corp.’s (“Denison”) U.S. mining assets and operations (the “US Mining Division”), as well as all of the inter-company debt between Denison and the US Mining Division. The transaction is being completed under a plan of arrangement (the “Arrangement”) in accordance with the Business Corporations Act (Ontario) which was previously approved by the Ontario Superior Court of Justice. All conditions of closing have now been satisfied by both parties. Under the Arrangement, the following transactions will take effect at 11:59 p.m. on June 29, 2012: (i) the US Mining Division and related inter-company debt will be transferred by Denison to Energy Fuels in exchange for a promissory note and a nominal amount of cash, (ii) Denison will complete a reorganization of its capital, including a distribution of the promissory note to its shareholders on a pro rata basis, and (iii) Energy Fuels will repay the promissory note by issuing approximately 1.106 common shares of Energy Fuels per Denison common share to the Denison shareholders, all as previously announced. Upon completion of the Arrangement, Denison shareholders will, in aggregate, hold approximately 63% of the issued and outstanding common shares of Energy Fuels.

Effective June 30, 2012, Energy Fuels has increased the size of its board to ten directors. Ron Hochstein, the President and Chief Executive Officer of Denison, and Robert Dengler, a Denison director, have been appointed as directors.

In addition, in connection with the closing of the transaction, the net proceeds of the private placement of subscription receipts completed by Energy Fuels on June 21, 2012 have been released from escrow and delivered to Energy Fuels. Energy Fuels issued 35,500,500 common shares and 17,750,250 common share purchase warrants on the conversion of the subscription receipts.
