Toronto, ON — March 23, 2009... Denison Mines Corp. (DML:TSX) (NYSE Amex:DNN) (“Denison” or the “Company”) reports that at the Annual Meeting of Shareholders on April 30, 2009, Mr. E. Peter Farmer will step down as Chief Executive Officer and as a Director of the Company. Candidates to replace Mr. Farmer have been identified and a search for other candidates has commenced.
Mr. Farmer has been with the Company since 1985 and has indicated that it is time for a change in leadership at Denison and the Annual Meeting is an appropriate time for this change.

Under Mr. Farmer’s leadership, Denison has grown to become a premier mid-tier uranium producer in North America. He has presided over the Company through good times as well as challenging times in the uranium market and throughout all cycles Denison has always maintained a reputation for excellence, dependability, and superior corporate governance.
The Board of Directors would like to thank Mr. Farmer for his outstanding contribution to Denison over the years. His dedication and loyalty to the Company are greatly appreciated and we wish him all the best in his future endeavours.
Lukas H. Lundin, Chairman of Denison, commented, “The Company is highly regarded and respected in the industry and that is due in no small part to Peter’s work over the years. I would like to express my personal gratitude to him and wish him the very best.”
