Is CCJ Prepared to Offset McArthur River Losses With Cigar Lake Gains?
Read MoreHide Full Article
Key Takeaways
CCJ cut its 2025 McArthur River production view to 9.810.5M lbs due to development delays.
CCJ saw a 32% drop at McArthur River, partly offset by stronger Cigar Lake output in 2025.
CCJ expects Cigar Lake and McClean Lake performance to help offset about 1M lbs of lost supply.
Cameco Corporation (CCJ - Free Report) had lowered its 2025 uranium production outlook earlier this year, citing development delays at the McArthur River mine. The mine located in northern Saskatchewan, Canada, is known as the largest high-grade uranium mine globally. CCJ holds a 69.805% stake in the mine
The Key Lake mill at the site is the world’s largest uranium mill (in which CCJ holds an 83.33% stake). The company also holds a 54.547% stake in Cigar Lake, the world’s highest-grade uranium mine.
CCJ’s attributable uranium production from these operations totaled 15 million pounds in the first nine months of 2025, down 13% year over year. Output at the McArthur River mine was down 32%, offset by a 16% rise at Cigar Lake.
As expected, production at the McArthur River mine had been impacted by the delays in transitioning into new mining areas. As a result of these delays, the Key Lake mill was shut down from Sept. 3 through Oct. 17, impacting production in the third quarter.
Cameco now expects its share of uranium production from the McArthur River mine at 9.8-10.5 million pounds in 2025 compared with the earlier forecast of 12.6 million pounds. The expected share of production from Cigar Lake remains at 9.8 million pounds for 2025.
Its expected 2025 share from Cigar Lake remains unchanged at 9.8 million pounds. Supported by strong performance at the Cigar Lake mine and the McClean Lake mill so far, Cameco remains optimistic that these operations will help offset roughly 1 million pounds (on a 100% basis) of the anticipated shortfall from McArthur River.
Cameco’s Peer Performances
Energy Fuels (UUUU - Free Report) produced approximately 465,000 pounds of uranium from its Pinyon Plain, La Sal and Pandora mines in the third quarter, bringing the year-to-date total to 1,245,000 pounds.
The Pinyon Plain mine has been a standout performer for Energy Fuels, with production ramping up significantly this year. Energy Fuels currently expects to mine ore from all of its mines containing approximately 875,000-1,435,000 pounds of contained uranium in 2025. Energy Fuels aims to process up to 1 million pounds of uranium this year.
Ur Energy (URG - Free Report) is currently operating the Lost Creek project in south-central Wyoming, which has an annual capacity of 1.2 million pounds. This company dried and packaged 93,523 pounds and shipped 70,190 pounds to the conversion facility in the third quarter. This brings the year-to-date total to 288,622 pounds. Ur Energy recently received final approval for the expansion of Lost Creek. The company is also progressing with construction at Shirley Basin, which will transform it into a two-mine operation. Shirley Basin has a licensed annual mine capacity of 1 million pounds.
