Production resumes

Cameco has restarted uranium production at its Cigar Lake mine in northern Saskatchewan. The restart followed Orano's return of the McClean Lake mill to service.

Cigar Lake ore is processed at McClean Lake, and stockpiled ore is now shipping to the mill. That restores the connection needed to move resumed mine output into processing.

Why the mill matters

The episode highlights an operational dependency: Cigar Lake output hinges on the availability of the McClean Lake mill. The restart removes a concrete near-term supply disruption, but it does not eliminate that dependency.

The next receipt to watch is continued mill reliability and whether ore shipments from Cigar Lake keep moving through McClean Lake. The supplied record does not provide production volumes, a restart date, or further operating guidance.

What to watch

Watch for evidence that McClean Lake remains available and that stockpiled and newly produced Cigar Lake ore continue shipping to the mill.
