$CCJForm 6-KFiled Jul 2, 2026, 11:41 AM ET0001193125-26-293855Original filing

Cameco has temporarily suspended mining at its Cigar Lake operation in northern Saskatchewan due to challenges at Orano's McClean Lake mill, where Cigar Lake ore is processed. The suspension follows a shutdown of the mill's sulfuric acid plant, which is undergoing repairs while Orano seeks alternative acid supply options. The company currently anticipates that the McClean Lake mill will return to operation in approximately two weeks. Cameco stated that it does not expect the disruption to impact its 2026 production outlook for Cigar Lake at this time.
