Cameco (CCJ) shares rose 3.4% on Thursday after the company said that it reaffirmed its 2026 production guidance and that the Key Lake mill and McArthur River mine have resumed full uranium production activities following a disruption due to flooding in Saskatchewan.

The timing to restore access to the primary supply route is being confirmed, but the company has been able to deliver the required volume of critical materials via the secondary route, the company said.

Risks of thawing and precipitation could lead to further road restrictions, resulting in delays in future deliveries, according to the company.
