McArthur River/Key Lake
- McArthur River/Key Lake, located in northern Saskatchewan, Canada is the world's largest high-grade uranium operation.
- In July, 2018, due to prolonged market weakness, the operation was placed into safe and sustainable care and maintenance.
- In service since 1999 and 1983 respectively, Cameco operates the ISO 14001 certified locations, which have collectively produced 535 million lbs using a variety of mining methods.
2020 Q1 Update
There was no production in the first quarter as a result of the planned production suspension that began in February 2018 and continues for an indeterminate duration due to continued weakness in the uranium market. The operation remains in a safe state of care and maintenance. A restart decision is a commercial decision that will be based on our ability to commit the production from this operation under acceptable long-term contracts.
Our share of the cash and non-cash costs to maintain both operations during the suspension is expected to range between $8 million and $10 million per month.
Environment & Safety
Worker safety, environmental monitoring and proper decommissioning, after mining is completed, are of the utmost importance to Cameco.
Reserves & Resources
Our mineral reserves and resources are the foundation of our company and fundamental to our success.
