Analysis · CCJ · Energy & Transportation
Production and ore shipments have resumed at Cameco's Cigar Lake uranium mine, and the McClean Lake mill is back online. The temporary halt, disclosed on July 2, stemmed from a sulfuric acid plant issue at Orano's McClean Lake mill. With the 2026 production outlook for Cigar Lake unchanged at 17.5–18.0 million pounds of U3O8 (100% basis), the disruption proved brief and had no material impact on annual targets. This removes a near-term operational overhang and reinforces the stability of Cameco's flagship asset.
