Overview
A Preliminary Economic Assessment (PEA) completed in August 2025 outlines a total potential production of 37.4 million pounds of U3O8 over the life of the mine. The potential annual average production is nearly 6.1 million pounds of U3O8. The PEA assumes that uranium-bearing solution recovered from the mine will be processed at the nearby McClean Lake mill.

A Preliminary Economic Assessment (PEA) completed in August 2025 outlines a total potential production of 37.4 million pounds of U3O8 over the life of the mine. The potential annual average production is nearly 6.1 million pounds of U3O8.
Processing
The PEA assumes that uranium-bearing solution recovered from the mine will be processed at the nearby McClean Lake mill, which is owned by Orano Canada (77.5%) and Denison (22.5%).
Expansion
In August 2025, Denison Mines Corp. announced the results of a Preliminary Economic Assessment for the potential use of In-Situ Recovery (ISR) mining at the Midwest Main deposit. The PEA is considered preliminary in nature and is based on Indicated and Inferred mineral resources. The joint venture is also evaluating the use of the Surface Access Borehole Resource Extraction (SABRE) mining method for the deposit.

End year
2027
Overview
The McClean Lake Joint Venture is a uranium mining and processing facility in the eastern Athabasca Basin. It includes a uranium mill, a tailings management facility, and associated infrastructure. The mill, one of the world's largest, has an annual licensed production capacity of 24 million pounds of U3O8 and processes ore from Cigar Lake and McClean Lake mining operations.
Production
For 2025, production from the McClean North deposit totalled 648,558 pounds of U3O8 (100% basis), with Denison's share at 145,926 pounds. The 2025 production target was 800,000 pounds of U3O8.
Processing
Uranium mill with an annual licensed production capacity of 24 million pounds of U3O8, processing ore from Cigar Lake and McClean Lake mining operations.
Expansion
Mining operations, suspended in 2008, restarted in June 2025 at the McClean North deposit using the patented Surface Access Borehole Resource Extraction (SABRE) mining method. An additional 3 million pounds of U3O8 has been identified for potential production from the McClean North and Caribou deposits between 2026 and 2030.

Gryphon

Saskatchewan, Canada · Underground

Under Development
Uranium
Mine life
6.5 years
Overview
The Gryphon deposit is part of the Wheeler River Project, the largest undeveloped uranium project in the eastern Athabasca Basin. It is a basement-hosted uranium deposit. A 2023 cost update to the 2018 Pre-Feasibility Study confirmed its potential as one of the world's lowest-cost uranium mines.
Production
Over an approximately 6.5-year mine life, 49.7 million pounds of U3O8 are planned to be extracted from 1,260,000 tonnes of ore grading 1.8% U3O8.
Processing
The plan assumes that ore from the Gryphon operation will be processed at the McClean Lake mill, which is 22.5% owned by Denison. The mill's existing flowsheet is considered amenable to processing the Gryphon ore with minimal required upgrades, and the estimated recovery rate is 98.2%.

Phoenix

Saskatchewan, Canada · Solution

Under Development
Uranium
Mine life
10 years
Workforce
The project is expected to generate benefits for employees, contractors, and Indigenous partners.
Production
First production is targeted for mid-2028. The Phoenix operation is anticipated to produce approximately six-million pounds of uranium oxide per year.
Processing
The Phoenix project will be the first uranium in-situ recovery (ISR) mining operation in the Athabasca Basin region. The ISR method involves injecting a solution underground to dissolve the uranium ore, which is then pumped to the surface for processing. A unique feature of the planned ISR mine is the use of artificial ground freezing around the perimeter of the mining areas to create a hydraulic barrier.
Equipment
Long-lead items procured for the project include electrical distribution infrastructure such as the main site transformer, substation high voltage equipment, switchgear, and a substation electrical house. A construction management contract has been awarded to Wood Canada Limited to oversee the building of the mine, including the processing plant and site infrastructure. Grid power was made available at the future mine site following the completion of a SaskPower transmission line.
Expansion
The Denison Mines Corp. Board of Directors made a Final Investment Decision to proceed with the construction of the Phoenix mine in February 2026. Site preparation and construction activities are planned to commence in March 2026. The construction period is expected to be approximately two years.

Historically, the Calliham mine produced about 222,000 tons of ore with average grades of 0.15% U3O8 and 0.92% V2O5. As of March 2015, the project had Measured and Indicated Mineral Resources of approximately 1,611,000 pounds of U3O8 and 13,261,000 pounds of V2O5, contained within roughly 475,100 tons of material.
