Production Start at McClean North
David Cates, President and CEO of Denison, expressed, "Denison has delivered several key accomplishments during the second half of 2025, demonstrating our ongoing re-emergence as a globally significant uranium producer."

Ongoing Development at Wheeler River
Furthering its commitments, Denison is in the final stages of the multi-year permitting process for the planned Phoenix In-Situ Recovery ('ISR') mine at Wheeler River. Key regulatory approvals have bolstered the Company's position, including recent Ministerial approval for the Environmental Assessment from Saskatchewan. An upcoming public hearing conducted by the Canadian Nuclear Safety Commission represents a critical step towards the project's advancement.
Regulatory Approvals and Engineering Progress
In a significant move, the first part of the public hearing has been completed, with the conclusion anticipated shortly. Cates highlighted, "We are optimistic that we will receive a decision from the Commission in early 2026." As of now, Denison has achieved roughly 85% completion of the detailed engineering design for the Phoenix ISR mine, with procurement efforts exceeding $27 million already invested.
Financial Growth and Strategic Positioning
Denison's financial position is bolstered by a robust total cash, investments, and uranium holdings nearing $720 million, allowing the company to advance its projects with confidence. This strong liquidity has enabled significant investments into both procurement and construction planning.
