- The title of world's largest uranium producer belongs to the McArthur River-Key Lake tandem operation located in northern Saskatchewan, Canada.
- Cameco operates both ISO 14001 certified locations which have been in production since 1999 and 1983 respectively.
- Combined, these two operations have reliably produced more than 518 million lbs using a variety of mining methods best-suited for the ground conditions.
Q2 2017 Update
Production was 29% higher for the second quarter, and 26% higher for the first six months compared to the same periods in 2016. Last year, outages to work on the existing calciner circuit, combined with the timing of the planned annual maintenance shutdown, resulted in reduced production during the first half of the year compared to 2017. This year, in alignment with our continued efforts to reduce costs, our production plan includes an extended summer shut-down during the third quarter. The shut-down consists of a four-week vacation period in July, followed by a two-week maintenance period at McArthur River and a four-week maintenance period at Key Lake, both of which are now underway. Production is expected to restart at the end of August. As a consequence of the summer shutdown, we expect third quarter production at McArthur River/Key Lake to be lower than the third quarter of 2016, which is expected to increase the quarterly unit production cost
