Production at Cameco’s Key Lake mill in Saskatchewan has been suspended due to a significant infrastructure issue. A bridge collapse, triggered by recent flooding, has obstructed the primary supply route.
Key Lake Mill Production Halted
The uranium mining company Cameco announced a pause in its operations at the Key Lake mill. This halt also affects activities at the McArthur River mine. The critical supply route, Highway 165, faced an unexpected bridge failure over the Smoothstone River.
Impact of the Bridge Collapse
While Cameco confirmed that its operations were not directly affected by flooding, the bridge collapse has imposed logistical challenges. The Smoothstone River Bridge served as the main transportation link for essential materials to both the Key Lake and McArthur River sites.
Details of the Incident
- Date of Incident: May 11, 2026
- Location: Key Lake, Saskatchewan
- Culprit: Smoothstone River Bridge collapse
- Supply Route Affected: Highway 165
Road restrictions have made it impossible to use alternative routes, complicating the situation further. Witnesses, including local resident Troy Lariviere, documented the collapse of the bridge as it fell into the turbulent waters.
Future Steps for Cameco
Cameco is currently assessing the situation to determine the timeline for resuming operations. Monitoring the flooding and evaluating safe transport for supplies will be crucial in the upcoming days.
