Cameco, Orano expand their dominance as they buy out partner in Saskatchewan uranium mine
Cameco and Orano Canada agreed to buy TEPCO Resources’ remaining 5% stake in the Cigar Lake uranium mine in northern Saskatchewan, giving them full joint ownership. Cameco will pay about C$115.75 million, lifting its stake to over 57%. Orano will raise its share to nearly 43%. Closing is expected in Q3; Cigar Lake output is forecast at 17.5–18 million pounds in 2026.
Deal increases Cameco’s controlling exposure to Cigar Lake output and extends mine life efforts, supporting longer-duration production visibility.
Cameco agreed to buy out TEPCO Resources’ remaining 5% stake in Saskatchewan’s Cigar Lake, lifting ownership above 57%.
Near-term upside bias as investors price higher effective stake and consolidation of cash flows; follow-through depends on closing Q3 and any financing/terms details.
Background
Cigar Lake is a major producing uranium mine in northern Saskatchewan; Cameco and Orano already have operating/ownership positions across the region.
Why it matters
By acquiring TEPCO Resources’ remaining 5% stake, Cameco increases its majority control and consolidates production economics, while Orano increases its minority position to nearly 43%. The operator also targets 17.5–18.0M lbs U3O8 concentrate output and aims to extend mine life to 2036.
Market relevance
Material M&A/asset consolidation for Cameco with explicit ownership and production/life-extension context; likely supportive for uranium equity positioning into Q3.
Market effects
Reinforces consolidation trend in high-quality, permitted uranium assets (Cigar Lake) and may support uranium equity sentiment broadly.
Highlights continued investment/ownership rationalization in Saskatchewan’s uranium basin.
Supports narratives around expanding nuclear fuel supply via scarce, licensed production capacity.
Alternative perspectives
The purchase price and any incremental economics vs. existing stake are not fully detailed (Orano value undisclosed), so market may discount if returns don’t clear hurdles.
Closing risk in Q3 and potential regulatory/operational constraints at Cigar Lake could temper the valuation lift despite higher ownership.
