Operation
2025 Q4 Update
The site remained in a safe state of care and maintenance throughout 2025.
While in standby, we continue to evaluate our options to minimize care and maintenance costs. We expect standby operating costs in care and maintenance to range between $44 million and $47 million in 2026, an increase from 2025 attributed to project work related to infrastructure maintenance.
Environment & Safety
Worker safety, environmental monitoring and proper decommissioning after project completion are of the utmost importance to Cameco.
