We are proud to mark a major milestone in Canada’s mining industry.

Site preparation and early works construction are underway at the Phoenix uranium mine, part of our flagship Wheeler River Project. This progress follows a successful ceremonial groundbreaking at site and a celebration in Saskatoon.

As Canada’s first-ever in-situ recovery (ISR) uranium mine and the first large-scale uranium project approved for construction in over 20 years, Phoenix represents a new era of innovation, sustainability, and collaboration.

In addition to the ceremonial groundbreaking earlier this month, we are proud to unveil the new Wheeler River project logo – another meaningful milestone for the project.

The logo reflects the values at the heart of Wheeler River: innovation, community, environmental stewardship, prosperity, and safety. These pillars capture our shared commitment – to the land, the water, and the people – as we responsibly advance uranium mining in northern Saskatchewan.

Last week marked an exciting and proud moment as we held a ceremonial groundbreaking for the Phoenix In-Situ Recovery (ISR) mine— commemorating the start of site preparation and early works construction.

We were thrilled to celebrate this momentous occasion alongside our Indigenous and local community partners and our construction management contractor, Wood Canada. Representatives from English River First Nation, Kineepik Métis Local, Métis Nation–Saskatchewan, and Ya’thi Néné Lands and Resources joined the Denison team for this special occasion.

Phoenix represents a bold step forward for the Canadian uranium mining industry – as the first uranium mine in the country to use the ISR mining method, and the first large-scale Canadian uranium mining project to be approved for construction in more than 20 years. This is a nation-building project that showcases the very best of Canadian mining ingenuity, collaboration, and determination.

Thank you to everyone who joined us on-site to celebrate this milestone achievement under the clear skies and bright sunshine of northern Saskatchewan.

Denison Mines Corp. is a uranium exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan.

Denison Reports Financial and Operational Results for Q1 2026, Highlighted by Commencement of Site Preparation and Early Works for the Phoenix ISR Uranium Mine, and the Results of its Shareholder Meeting.

David Cates, President and CEO of Denison commented, "In February, the Phoenix In-Situ Recovery ("ISR") uranium mine ("Phoenix") became the first large-scale Canadian uranium mining project in over 20 years to receive all regulatory approvals required to commence construction. Shortly after achieving this landmark permitting accomplishment, the Company made its final investment decision ("FID") for Phoenix construction and, by the end of the first quarter, our Denison-Wood integrated project management team mobilized to the Wheeler River property and began executing schedule-critical site preparation and early works construction activities.

In less than two months of on-site activity, our dedicated teams have completed (i) tree clearing activities across the primary mine site area, (ii) installation of construction management facilities, (iii) construction of our on-site helipad, (iv) civil works for the concrete batch plant pad, and (v) commencement of aggregate production at a nearby quarry. Civil activities continue to advance on site, including those necessary to establish the future airstrip. Taken together, we are on track to ramp up construction staffing and activities to complete early works and commence full-scale construction by the end of the second quarter, which aligns with our target to achieve first uranium production in mid-2028. We are, however, closely monitoring the widespread flooding that is impacting a portion of the road network in northern Saskatchewan. While our personnel are able to access the Phoenix site via helicopter, our ability to mobilize additional heavy equipment and certain supplies to site as planned may be impacted if the flooding persists and/or key infrastructure remains impacted. We recognize the significant efforts of the Province of Saskatchewan to rapidly respond to this unprecedented situation and are hopeful that conditions will improve in the coming days."
