  • Operational Disruption

    Flooding has caused the collapse of the Smoothstone River Bridge, a primary supply route to McArthur River and Key Lake sites, and restricted an alternative roadway.

  • Production Halted/Reduced

    Production activities at the Key Lake mill are temporarily halted, and activity at the McArthur River mine is reduced.

  • Uncertain Timeline & Outlook Risk

    The timeline for resuming normal deliveries is unknown, and there is a risk that the 2026 production outlook for the McArthur River/Key Lake operation could be impacted, despite the Cigar Lake mine continuing to operate and the consolidated annual production plan remaining unchanged for now.
