Denison to Proceed to Compulsory Acquisition of White Canyon Uranium Limited

TORONTO, ONTARIO--(Marketwire - June 20, 2011) - Denison Mines Corp.(TSX:DML)(NYSE Amex:DNN) ("Denison") is pleased to announce that its Offer to acquire all of the outstanding shares of White Canyon Uranium Limited ("White Canyon") (TSX VENTURE:WU)(ASX:WCU) announced in February 2011, closed on June 17, 2011 with Denison receiving acceptances of 96.98% under the Offer. Denison now intends to proceed with the compulsory acquisition of the remaining shares of White Canyon and the delisting of White Canyon's shares from both the Toronto Stock Exchange and the Australian Securities Exchange.

White Canyon's key assets are located in southeastern Utah, near Denison's White Mesa mill. Its holdings comprise 100% interests in the advanced Thompson, Daneros, Lark Royal, Geitus, Blue Jay and Marcy Look Projects, covering approximately 15,500 acres in the Red Canyon district. White Canyon commenced uranium production in December 2009 from its 100% owned Daneros Uranium Mine.

The acquisition of White Canyon fits well into Denison's growth strategy. White Canyon's Daneros Uranium Mine will become Denison's fourth U.S. operating mine, providing additional ore feed to its 100% owned White Mesa mill.

Ron Hochstein, Denison's President and Chief Executive Officer, stated that "the acquisition of White Canyon is a good strategic move for Denison because it provides additional flexibility for our White Mesa milling schedules, and adds to Denison's resource inventory and exploration potential in a region of core focus."
