Cameco Halts Key Lake Production, Reduces McArthur River Activity
AI Summary
Cameco Corporation announced a temporary halt in production at its Key Lake mill and reduced activity at its McArthur River mine due to regional flooding impacting roadways. The collapse of the Smoothstone River Bridge, a primary supply route, and restrictions on an alternative road have disrupted the delivery of critical operating materials. While the Cigar Lake mine continues to operate and the consolidated annual production plan remains unchanged for now, there is a risk that the 2026 production outlook for the McArthur River/Key Lake operation could be impacted depending on the duration of road restrictions.
