CCJ Cuts McArthur Rive Output Outlook: Can Cigar Lake Bridge the Gap?
Read MoreHide Full Article
Key Takeaways
Cameco cut 2025 McArthur River guidance to 14-15M pounds due to delays and slower ground freezing.
First-half 2025 output fell 18% year over year, with McArthur down 35% and Cigar Lake up 8%.
CCJ sees Cigar Lake helping offset up to 1M pounds of the McArthur River production shortfall.
Cameco Corporation (CCJ - Free Report) has revised its 2025 production outlook, projecting a 19% drop in its share of output from the McArthur River mine compared with its previous expectation. This shortfall is due to development delays in transitioning the mine to new mining areas as well as slower-than-anticipated ground freezing.
Cameco holds a 69.805% stake in the McArthur River mine and 83.33% in the Key Lake mill. McArthur River is known as the largest high-grade uranium mine globally and Key Lake is the world’s largest uranium mill. CCJ also holds a 54.547% stake in Cigar Lake, the world’s highest-grade uranium mine.
In the first half of 2025, Cameco’s share of combined production from McArthur River/Key Lake and Cigar Lake was 10.6 million pounds, down 18% year over year. This was mainly due to a 35% decline in the McArthur River mine’s output, reflecting its annual maintenance shutdown in the second quarter of 2025. Meanwhile, Cameco’s share from the Cigar Lake mine was 5.5 million pounds, 8% higher year over year.
Earlier, Cameco had provided an outlook of 18 million pounds of uranium production (100% basis) from each of McArthur River/Key Lake and Cigar Lake operations in 2025. This meant an expected 12.6 million pounds from McArthur and 9.8 million pounds from Cigar Lake.
Production from the McArthur River/Key Lake operation is now projected at 14-15 million pounds of uranium concentrate (on a 100% basis), suggesting Cameco’s share at 9.8-10.5 million pounds.
The Cigar Lake mine’s production guidance for 2025 is maintained at 18 million pounds of uranium on a 100% basis, with CCJ’s share expected at 9.8 million pounds. Backed by Cigar Lake’s upbeat performance in the first half and expecting the momentum to continue, Cameco expects it will likely help set off up to 1 million pounds (100% basis) of the production shortfall at the McArthur River.
