Cameco Increases Cigar Lake Stake through a C$115.75 million acquisition that strengthens its position in one of the world’s highest-grade uranium mines. The company purchased a portion of TEPCO’s former interest in the Cigar Lake operation in northern Saskatchewan.
The transaction increases Cameco’s ownership to 57.4%, while Orano Canada now holds the remaining 42.6%. The partners finalized the deal after exercising their right of first refusal, securing additional access to high-grade uranium reserves as global demand for nuclear fuel continues to grow.
Transaction Details and Strategic Value
The total transaction value reached C$115.75 million, equivalent to approximately US$116.8 million. TEPCO exited its 5% joint venture interest, marking a notable shift as utilities increasingly move away from direct mining ownership. Instead, many utilities now prefer long-term supply agreements. Consequently, Cameco and Orano moved quickly to acquire the available interest. The purchase increased Cameco’s stake from 50% to 57.4%, while Orano’s ownership rose from 37.1% to 42.6%.
Furthermore, the deal reflects confidence in the uranium sector. The uranium market outlook 2026 remains strong as buyers seek secure access to future uranium supply.

Cigar Lake Asset Profile
Cigar Lake contains approximately 172 million pounds of uranium reserves. Additionally, the deposit features an average ore grade of about 15% U3O8, making it one of the highest-grade uranium deposits in the world. The mine uses specialized jet boring technology to reduce radiation exposure for workers. Meanwhile, frozen ground systems help control water inflow, supporting safe mining operations in a challenging environment.
The remote operation sends its ore to the McClean Lake processing facility, which Orano operates roughly 80 kilometers away. This integrated arrangement helps lower operating costs and improves efficiency. Moreover, the partners plan to continue production through 2036, extending the long-term value of the asset.
Production Targets for 2026
The mine has set a production target of between 17.5 million and 18 million pounds for 2026. Cameco’s share is expected to be approximately 10 million pounds, while Orano will receive the remaining production. Reliable uranium supply has become increasingly important for global nuclear power generation. As a result, western nations continue seeking secure and diversified uranium sources outside Russia.
The uranium price forecast 2026 also supports ongoing investment. Prices remain above US$80 per pound, while some analysts expect uranium prices to reach US$100 per pound. In addition, Cigar Lake’s high grades help maintain low operating costs and strong margins.

Why TEPCO Exited the Mine
TEPCO continues to reshape its global investment portfolio. The company faces growing financial requirements in its domestic energy business and has chosen to reduce direct exposure to mining operations. However, TEPCO remains an important uranium customer for Cameco through existing long-term supply agreements. Selling its ownership stake simplifies the company’s portfolio while reducing operational risk.
Many industry observers expected this move. Although TEPCO exited the mine, Japan’s reactor restart program continues to support future uranium demand.
Orano Canada and the Mill Nexus
Orano plays a critical role in the Cigar Lake operation through its management of the McClean Lake mill. The facility processes extremely high-grade uranium material and serves as a key component of the project’s success. Therefore, Orano’s increased ownership aligns naturally with its processing capabilities. The additional stake provides greater feedstock security for the mill and supports efficient operations.
Furthermore, Orano continues exploration activities across the Athabasca Basin. The company is seeking additional uranium discoveries near existing operations. Its long-standing partnership with Cameco remains central to the project’s development.

Market Context and Demand Drivers
Nuclear power is experiencing renewed global interest. Growing electricity demand from data centers and artificial intelligence infrastructure is increasing the need for reliable, carbon-free energy sources. Major technology companies, including Microsoft and Amazon, have shown increasing interest in nuclear-generated electricity. Meanwhile, the development of Small Modular Reactors (SMRs) is expected to support future uranium demand growth.
New uranium mines require years of permitting and development. Consequently, expanding ownership in existing tier-one assets provides a faster path to securing future production. Cameco continues to strengthen its position through ownership of high-quality uranium assets.
Geopolitical Shifts in Supply
Global uranium supply chains continue to evolve amid geopolitical changes. Russia maintains a significant presence in uranium enrichment and related nuclear fuel services.
As a result, western countries are pursuing alternative supply sources. Canada remains one of the most attractive mining jurisdictions due to its stable regulatory environment, established infrastructure, and low political risk. The Athabasca Basin remains a world-class uranium-producing region. Saskatchewan offers strong infrastructure, skilled workers, and a supportive mining environment, making future development opportunities more accessible.

Future Milestones and Expansion
The Cigar Lake partners are already planning beyond 2030. The mine’s current operating licence expires in 2031, and preparations for future regulatory approvals are underway. Public hearings related to licence extensions are expected to begin next year. In addition, the project will require new freeze pad construction to support future mining activities.
Technicians continuously monitor ground conditions to maintain safety standards. Furthermore, Cameco continues investing in local communities and works closely with Indigenous partners throughout the region. Local Saskatchewan businesses also play an important role through service contracts that support ongoing mine operations. This strong community engagement helps maintain long-term project support.
Summary of the $115M Deal
Cameco Increases Cigar Lake Stake through a strategic acquisition that strengthens its control of one of the world’s premier uranium assets. The transaction raises Cameco’s ownership to 57.4%, while Orano Canada now holds 42.6%. The C$115.75 million deal secures additional access to high-grade uranium reserves and supports production plans through 2036. Moreover, the mine is targeting up to 18 million pounds of uranium production in 2026.
As global nuclear energy demand continues to rise, Canada remains a reliable source of uranium supply. Consequently, investors view the transaction as a significant step in securing future production from a world-class uranium operation.
