Canada’s Denison Mines has agreed to sell its American assets to Energy Fuels in a transaction the companies said will create the “largest 100 percent U.S. pure-play uranium producer and one of the largest holders of National Instrument 43-101 compliant U.S. based uranium resources.”The combined U.S. company would control measured and indicated resources of 49.8 million pounds of U308 and another 17.9 million pounds of inferred resources.“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,” Energy Fuels CEO Steve Antony said in a release.The recently signed letter of agreement between the companies calls for Denison stockholders to acquire 66.5 percent of Energy Fuels’ outstanding stock. Based on Monday’s stock prices, Bloomberg estimated the value of the deal at $107.5 million. Following the announcement, Denison’s stock price was up 17 percent at the close Tuesday.
