Denison Mines Corp. announced the appointment of Mr. Ron F. Hochstein as Chair of the Board of Directors ("Board Chair"). Mr. Hochstein was elected Board Chair, and Mr. Brian Edgar was elected Lead Director, at a meeting of the Company's independent directors following the Company's Annual General Meeting. The Company also welcomed David Neuburger and Jennifer Traub to the Board of Directors. 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.
