Q3 2017 Update


Total packaged production from Cigar Lake was 11% lower in the third quarter, and 5% higher in the first nine months compared to the same periods last year. Packaged production was lower in the third quarter due primarily to the planned summer shutdown for maintenance and vacation. The shutdown went as planned with the mine and mill returning to full production as scheduled at the end of August. The year-over-year increase is the result of the scheduled rampup of the operation.
