- Cigar Lake is the world's highest grade uranium mine and is located in northern Saskatchewan, Canada.
- Since commissioning in 2014, the site has produced a total of 64.9 million pounds (100% basis). Commercial operation began in May 2015.
- As the operator, Cameco developed an innovative jet-boring technique specifically for this challenging deposit.
- Cigar Lake's ore is processed 70 km northeast, at the McClean Lake mill, operated by Orano.
2019 Q3 Update
Total production from Cigar Lake was 7% lower in the third quarter compared to the same period last year. Production remains on track to meet our forecast for the year.
The collective agreement between Orano and unionized employees at the McClean Lake mill expired on May 31, 2019. On October 15, 2019, the parties applied for conciliation, after a tentative agreement was not ratified by unionized employees. The conciliation period will run for 60 days and, if an agreement is not reached, can be extended by mutual consent. If not extended, there is a 21 day cooling-off period prior to either party acquiring the legal right to undertake a work stoppage. Work continues under the terms of the expired collective agreement during conciliation. If Orano is unable to reach an agreement and there is a work stoppage, there is a risk to production plans for 2020
