Cameco Stock news
On July 3, 2026, Cameco Corporation (FRA: CJ6) confirmed the temporary suspension of mining operations at its Cigar Lake uranium mine in northern Saskatchewan. The halt is a result of operational challenges at Orano Canada's McClean Lake mill, where an expansion joint failure in the sulfuric acid plant has disrupted ore processing. While Cameco currently maintains its 2026 production guidance of 17.5 to 18.0 million pounds, the company cautioned that a prolonged repair period beyond the estimated two weeks could impact annual output. This supply--side disruption highlights the vulnerability of the high--grade uranium supply chain to critical reagent availability.
