Cigar Lake 2017 Production Trend

2018 Q3 Update


Total packaged production from Cigar Lake was 12% lower in the third quarter and 2% higher for 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 at the end of August. Production remains on track to meet forecast for the year.
