Cameco Corp. (TSX:CCO; NYSE:CCJ) announced today that its Key Lake mill and McArthur River mine have returned to full production after a flooding disruption in northern Saskatchewan.
The company maintains its 2026 consolidated production outlook at 19.5-21.5 million pounds U3O8. The uranium producer, with a $46.8 billion market cap, delivered 79% returns over the past year.
On May 10, Cameco halted production at Key Lake and reduced operations at McArthur River due to flooding. The Smoothstone River bridge partially collapsed, causing traffic restrictions on an alternative road.
Cameco is in contact with Saskatchewan Ministry of Highways to restore the primary route. Full operations resumed using a secondary road for critical material deliveries.
Spring thaw and precipitation may cause further delays. The Cigar Lake mine was unaffected and continues operating. Cameco's 2026 production plan remains unchanged.
The company has a strong financial position with more cash than debt. This information is based on a press release from Cameco.
