The McArthur River and the Key Lake Operations have been in care and maintenance since February 2018. In November 2017, Cameco and its joint venture partner Orano Canada Inc. announced production from these operations would be temporarily suspended by the end of January 2018 for an expected duration of 10 months. In July 2018, the partners announced that the production suspension would continue for an indeterminate duration due to continued weakness in the uranium market.

Summary:

High-grade ore slurry arriving at the Key Lake ore slurry receiving plant is unloaded from the truck mounted containers by a vacuum aspiration system and pumped to one of four large air agitated slurry storage pachucas.

McArthur River low-grade mineralization and legacy low-grade mineralized waste stored at Key Lake on the low-grade mineralization blend pads is delivered to the grinding circuit grizzly by loader. The grinding circuit consists of a SAG mill in open circuit with a sizing screen. The screen oversize reports to the ball mill in closed circuit with two sizing screens. The undersize from all three screens report to the neutral thickener. The neutral thickener overflow is combined with industrial water to be re-used throughout the circuit.

High-grade ore slurry is withdrawn from the ore storage pachucas and pumped to the blending tank where it is mixed with the neutral thickener underflow. The resulting slurry is pumped to one of three storage pachucas ........
