PRESS RELEASE

DENISON OFFER TO ACQUIRE OMEGACORP LIMITED CLOSES Toronto, ON – April 13, 2007...

Denison Mines Corp. (“Denison” or the “Company”) (DML:TSX) reports that its offer to acquire any or all of the issued and outstanding shares of OmegaCorp Limited (“OmegaCorp”) (OMC:ASX) originally announced on December 5, 2006 has closed. Denison now owns approximately 51 million common shares representing approximately 33% of the issued capital of OmegaCorp, having paid a price of $AU1.15 per share. Denison has received a press release dated April 12, 2007 issued by Central African Mining and Exploration Company Plc (“CAMEC”) that states that CAMEC has announced an all share bid for OmegaCorp and is offering one CAMEC share, to which CAMEC attributes a value of AU$1.44, for every OmegaCorp share. The CAMEC bid is subject to a minimum acceptance of 50.1% and a number of other conditions. Denison is evaluating its options, among which include tendering into the bid or retaining its 33% share ownership. Denison Mines Corp. is the premier intermediate uranium producer in North America, with mining assets in the Athabasca Basin Region of Saskatchewan, Canada and the southwest United States including Colorado, Utah, and Arizona. Further, the Company has ownership interests in two of the four uranium mills operating in North America today. The combination of a diversified mining asset base with parallel ownership of milling infrastructure in highly politically stable jurisdictions has uniquely positioned the Company for growth and development into the future. The Company also has a strong exploration portfolio with large land positions in the United States, Canada and Mongolia. Correspondingly, the Company has one of the largest uranium exploration teams among intermediate uranium companies.
