('Denison' or the 'Company') (TSX: DML) (NYSE American: DNN) is pleased to announce that it has published its 2022 ESG Report.  Annually, Denison provides a report on its environmental, social and governance ("ESG") initiatives for its operations, demonstrating the Company's ongoing commitment to sustainability and transparency.

David Cates , President and CEO of Denison commented, " Denison has positioned itself to be an important contributor to the global clean energy transition, with our portfolio of uranium mining, development and exploration projects clearly linked to growing appreciation of the critically important role that nuclear energy must play in the battle against climate change.

As just one example of our efforts in 2022, we achieved a notable milestone in the permitting process for the planned Phoenix in-situ recovery mining project on the Wheeler River property with the submission of a draft Environmental Impact Statement ('EIS'), which follows from several years of baseline environmental data collection, technical assessments, and extensive engagement and consultation with Indigenous and non-Indigenous interested parties. The draft EIS demonstrates that the project can be constructed, operated, and decommissioned in a manner that has fewer residual effects remaining after mitigation than conventional open pit or underground mining and milling operations – potentially achieving a superior standard of environmental sustainability and re-shaping the future of uranium mining in Saskatchewan.

Our 2022 ESG Report demonstrates that the principles of good ESG practices are present throughout our organization, providing a solid foundation for our future growth and contribution to a clean energy future. "

Denison's 2022 ESG Report focuses on key ESG topics including the Company's objective to maintain excellence in corporate governance practices, "best in class" engagement with communities potentially impacted by its activities, diversity in the Company's workforce, and robust assessments of the environment and biodiversity in the regions within which it operates.

About Denison

Denison is a uranium exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada . The Company has an effective 95% interest in its flagship Wheeler River Uranium Project, which is the largest undeveloped uranium project in the infrastructure rich eastern portion of the Athabasca Basin region of northern Saskatchewan . A Pre-Feasibility Study was completed for Wheeler River in late 2018, considering the potential economic merit of developing Phoenix as an in-situ recovery ('ISR') operation and the Gryphon deposit as a conventional underground mining operation. Denison's interests in Saskatchewan also include a 22.5% ownership interest in the McClean Lake Joint Venture, which includes several uranium deposits and the McClean Lake uranium mill, which is contracted to process the ore from the Cigar Lake mine under a toll milling agreement, plus a 25.17% interest in the Midwest Main and Midwest A deposits and a 67.41% interest in the Tthe Heldeth Túé ('THT', formerly J Zone) and Huskie deposits on the Waterbury Lake property. The Midwest Main, Midwest A, THT and Huskie deposits are located within 20 kilometres of the McClean Lake mill.

Through its 50% ownership of JCU, Denison holds additional interests in various uranium project joint ventures in Canada , including the Millennium project (JCU, 30.099%), the Kiggavik project (JCU, 33.8118%) and Christie Lake (JCU, 34.4508%).

Denison's exploration portfolio includes further interests in properties covering ~300,000 hectares in the Athabasca Basin region.

Denison is also engaged in post-closure mine care and maintenance services through its Closed Mines group, which manages Denison's reclaimed mine sites in the Elliot Lake region and provides related services to certain third-party projects.
