Severe flooding in northern Saskatchewan has forced Cameco (TSX:CCO,NYSE:CCJ) to suspend production at its Key Lake uranium mill and scale back operations at the McArthur River mine.

The Canadian uranium giant announced that while floodwaters have not directly inundated its northern sites, the collapse of the Smoothstone River Bridge has severed a critical supply artery. The bridge serves as the primary transport route for essential operating materials heading to the Key Lake and McArthur River facilities.
