Company Overview and Operations

Denison Mines Corp. is a leader in the uranium mining sector, focusing on development and exploration, particularly in the Athabasca Basin of northern Saskatchewan, Canada. Notably, the company possesses a 95% interest in its flagship Wheeler River project, recognized as the largest undeveloped uranium project in the resource-rich eastern section of this significant mining region.

In 2023, Denison completed a pivotal feasibility study for the Phoenix deposit aimed at creating an In-Situ Recovery (ISR) operation. Additionally, the firm updated its 2018 Pre-Feasibility Study (PFS) for the Gryphon deposit, which outlines a conventional underground mining operation. These developments position Denison to potentially align with the world’s lowest-cost uranium mining operations.

Recent Developments in Mining Operations

Denison’s efforts to advance its mining projects took a major step forward in 2019 when permitting for the Phoenix project started. By July 2025, the company successfully received approval for the Environmental Assessment (EA) from the Province of Saskatchewan. This was followed by a federal approval in February 2026, allowing construction to begin on the Phoenix ISR Uranium Mine. Such advancements indicate Denison's robust pipeline and strategic planning capabilities as it moves forward.

Moreover, the mining company also highlights its interest in other projects within Saskatchewan. This includes a 22.5% ownership stake in the McClean Lake Joint Venture (MLJV), which recommenced mining operations with SABRE in 2025, and a shared ownership in other significant deposits like the Midwest Main and Midwest A deposits. These comprehensive interests, totaling approximately 457,000 hectares in the Athabasca Basin, exhibit Denison’s expansive footprint in the uranium sector.

Future Outlook for Denison Mines

Looking ahead, Denison Mines Corp. focuses on leveraging its robust portfolio and the favorable mining rights in Saskatchewan to reinforce its position within the competitive landscape of uranium mining. As it approaches significant milestones, the company remains optimistic about its capabilities to meet market demands and achieve sustainable growth.

Denison also recognizes the importance of communication and investor relations, actively inviting stakeholders to engage with their resources to remain informed about their evolving projects and overall corporate performance.

In conclusion, Denison Mines Corp. strikes a careful balance between executing its operational goals while consistently providing transparency and informative updates to its stakeholders. The 2025 Annual Report is a testament to this commitment, showcasing the company's alignment with best practices in corporate governance as well as a dedication to environmental stewardship in the mining industry.
