Denison Mines Corp. Announces Board Appointments

Lukas Lundin, the Company's outgoing Executive Chairman, commented "I am pleased to welcome several new Directors to the Company's Board, including Denison's President and CEO, David Cates.  Under David's leadership, the Company has executed on its strategic plan to divest its non-core international assets and position itself as the leading junior developer in the eastern Athabasca Basin. Denison is the Lundin Group of Companies' flagship uranium investment, and we are expecting tremendous growth ahead in this sector – especially now that we are seeing significant supply cuts from the largest uranium producers, which should fundamentally improve the oversupply situation that has plagued the commodity for the last several years.   

With that view in mind, as I step down from my formal duties as Chairman, I am delighted that one of my sons, Jack Lundin, will be joining the Company at such an exciting time – serving as a Director and representing the Lundin family interest at the Board level.  Jack brings significant technical and project development experience to the Company and will be a great asset to Denison as the Company moves towards the development of its high-grade Wheeler River project."    

In addition to the changes in the members of the Company's Board of Directors, Catherine J.G. Stefan, previously serving as the Company's Lead Independent Director, has been appointed non-executive Chair of the Board of Directors.
