Cameco Corporation and Orano Canada have reached a definitive agreement to acquire the 5 % participating interest that TEPCO Resources currently holds in the Cigar Lake Joint Venture, a world‑leading high‑grade uranium operation located in northern Saskatchewan. The transaction, valued at roughly C$115.75 million, will lift Cameco’s ownership to 57.418 % and Orano’s to 42.582 % once the deal closes in the third quarter of 2026. By consolidating a larger share of this tier‑one asset, Cameco not only deepens its exposure to one of the highest‑grade uranium mines on the planet but also reinforces the long‑term supply foundation that utilities and grid planners depend on as nuclear power seeks to expand its share of global electricity generation. The acquisition underscores Cameco’s strategic emphasis on “scarce, licensed, permitted assets” and reflects the company’s confidence in Cigar Lake’s ability to deliver low‑cost, reliable uranium well into the next decade.
Cameco Increases Ownership in Cigar Lake Mine
Cameco (TSX: CCO; NYSE: CCJ) and Orano Canada Inc. will each purchase a portion of TEPCO’s interest, thereby rebalancing the joint‑venture structure. After the closing, Cameco’s stake rises by 2.871 percentage points to 57.418 %, while Orano’s share climbs by 2.129 percentage points to 42.582 %. The purchase price of approximately C$115.75 million is subject to customary closing adjustments and will require regulatory clearances and standard closing conditions before it becomes effective. Tim Gitzel, Cameco’s Chief Executive Officer, highlighted the strategic fit, stating that “Cigar Lake is among the world’s best uranium mines, producing the highest‑grade uranium ore from a safe, reliable, and cost‑effective operation.” He added that increasing ownership “further demonstrates our commitment to our strategy, with scarce, licensed, permitted assets like Cigar Lake playing an essential role in fueling global ambitions to expand nuclear energy generation.” The transaction is slated for completion in Q3 2026, after which the ownership percentages will be reflected in each partner’s balance sheet and in future production allocations.
Cigar Lake Reserve Base and Production Outlook
The Cigar Lake deposit remains one of the richest uranium resources globally. As of 31 December 2025, proven and probable reserves are estimated at 172.4 million pounds of U₃O₈. In addition, measured and indicated resources total approximately 26.3 million pounds, while inferred resources add another 20.0 million pounds on a 100 % basis. Since the mine began commercial production in 2014, it has already delivered about 174.5 million packaged pounds of uranium concentrate (U₃O₈) to customers, confirming its high‑grade, high‑throughput profile. Looking ahead, Cameco projects 2026 production between 17.5 million and 18 million pounds of U₃O₈ on a 100 % basis, a range that reflects both the existing CLMain mining area and the anticipated contributions from the upcoming Cigar Lake extension (CLExt). These figures reinforce the mine’s role as a cornerstone of the global uranium supply chain, especially as utilities seek stable, long‑term contracts to support new nuclear builds.
Capital Projects and Timeline to 2026
The 2026 operating plan calls for continued extraction from the current mining zone, designated CLMain, while simultaneously advancing the Cigar Lake extension (CLExt) that is essential for extending the mine’s life to 2036. Key CLExt capital projects slated for 2026 include the construction of a freeze pad, the installation of a freeze‑distribution system, and the development of extensive underground infrastructure to support deeper ore access. These projects are designed to maintain the mine’s low‑cost profile and to ensure that the high‑grade ore body remains safely and efficiently accessed. Capital spending is expected to stay aligned with Cameco’s disciplined contracting and capital‑allocation strategy, meaning that expenditures will be carefully managed to avoid overruns while still delivering the necessary infrastructure on schedule. Successful execution of these projects will be pivotal for meeting the 2036 life‑extension target and for preserving Cigar Lake’s status as a benchmark low‑cost uranium producer.
Key Takeaways
- Cameco’s ownership in Cigar Lake rises to 57.418 % after acquiring TEPCO’s 5 % interest for about C$115.75 million.
- Proven and probable reserves at Cigar Lake stand at 172.4 million pounds of U₃O₈, with 2026 production targeted at 17.5‑18 million pounds.
- Capital projects for the CLExt extension, including a freeze pad and underground infrastructure, are slated for 2026 to sustain operations through 2036.
EnergyInsyte's Take
The increased stake gives Cameco a larger share of a high‑grade, low‑cost uranium asset, reinforcing supply certainty for nuclear‑fuel buyers. Execution risk centers on regulatory clearance and the timely delivery of CLExt infrastructure. Energy executives should monitor the Q3 2026 closing and the progress of the extension projects as indicators of future uranium availability and price stability.
