Cameco announced today that its Cigar Lake mine in northern Saskatchewan has resumed production. It had temporarily suspended production after Orano’s McClean Lake mill experienced challenges. McClean Lake is where Cigar Lake Ore is processed.

At the beginning of the month Orano’s McClean Lake mill had encountered operational challenges with its sulfuric acid plant that caused it to shut down in order to repair the issue.

Cameco says it has limited ore storage capacity at Cigar Lake, so the company had to temporarily suspended mining activities

Cameco, headquartered in Saskatoon, is one of the largest global providers of uranium. The company says its 2026 production outlook range for Cigar Lake has not been impacted by the temporary suspension of production.
