Ron Hochstein , Denison's Board Chair, commented, "I am honoured to have been elected Chair of Denison's Board by the Company's independent directors.  This is a very exciting and important time in the modern history of Denison – as the Company focuses on advancing its low-cost Phoenix In-Situ Recovery ('ISR') uranium development project, at a time when the uranium market is showing signs of a sustained recovery.

Navigating years of challenging uranium markets, with a view of building a sustainable low-cost uranium mining company, has taken great vision from the Company's Board and management.  Accordingly, on behalf of the Board of Directors, I would like to thank Catherine Stefan and Jack Lundin for their contributions to the Board, and specifically express our appreciation to Ms. Stefan, the Company's outgoing Board Chair, for her legacy of leadership and oversight of the Company during her six year term as Chair and Lead Director and 17 year tenure as a Director of the Company and its predecessor Denison Mines Inc."

David Cates , Denison Director and President & CEO, added, "We are also pleased to welcome the addition of two highly qualified new Directors to join Denison's Board. Jennifer Traub serves as Co-Chair of the Mining Group at Cassels Brock & Blackwell LLP and has been recognized as a legal leader in the Canadian resource sector.  Joining Jennifer as a new Director is Dave Neuburger .  Few people have the same caliber of directly applicable technical experience that Dave brings to our Board – including previous executive oversight of Cameco's international ISR mining operations and various mining operations in the Athabasca Basin."

While both Mr. Hochstein and Mr. Edgar are considered by the Board to be independent, the appointment of Mr. Edgar as Lead Director is a corporate governance initiative designed to enhance the Company's overall governance practices by further capitalizing on the diversity of qualifications that each of Denison's directors brings to the Board – including Mr. Edgar's 30-plus years of experience serving on public company boards and 16 years of practice in corporate and securities law.
