Cameco (TSX: CCO; NYSE: CCJ) is continuing its operations at its northern Saskatchewan sites amidst wildfires that are impacting parts of the province.

Currently, there are no fires in the vicinity of Cameco’s operations at Cigar Lake, Key Lake, McArthur River and Rabbit Lake. There is no risk to our sites, and they remain safe for staff. Orano’s McClean Lake mill remains operational.

We are managing some temporary disruptions due to wildfires impacting power and communication services to our operations. Road closures have also impeded some deliveries to sites.

Most importantly, Cameco has many employees who are from northern communities threatened by wildfires or under evacuation orders. We are accommodating their requests to leave site to tend to family and provide aid to their home communities.

As our sites continue to operate, the safety of our staff is our top priority. We are taking measures to minimize the impact of the disruptions, including making operational adjustments as we manage the availability of employees. At this time, our annual production target remains unchanged.
