Cigar Lake

- 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 105 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.

1 In Q2, we updated our Cigar Lake production forecast to 18 million pounds (100% basis) in 2022 (previously 15 million pounds) as we have been successful in catching up on development work that had been deferred from 2021. However, the potential for supply chain challenges impacting the availability of construction materials, equipment and labour remains uncertain and could reintroduce production risk.
As announced in May 2022, we along with Orano acquired Idemitsu Canada Resources Ltd.’s 7.875% participating interest in the Cigar Lake Joint Venture. Our ownership stake in Cigar Lake now stands at 54.547%, 4.522 percentage points higher than it was prior to the transaction.
Our share of production for the third quarter in 2022 was 2 million pounds, the same as the third quarter of 2021. Our share of production in the first nine months of 2022 was 6.6 million pounds compared to 3.3 million pounds in the first nine months of 2021. Production was impacted by suspensions until mid-April in 2021 as a precautionary measure due to COVID-19. Our share of production has been updated to reflect the ownership increase effective May 19.
In 2022, we expect to produce 18.0 million pounds at Cigar Lake; our share is approximately 9.5 million pounds. We have been successful in catching up on development work that had been deferred from 2021. However, the potential for supply chain impacts on construction materials, equipment and labour remains uncertain and could reintroduce production risk in 2022 and future years.
Continuing to align our production with the market conditions and our contract portfolio, starting in 2024, we will target production from Cigar Lake that is 25% below the licensed capacity, or 13.5 million pounds (100% basis) per year. This will remain our production plan until we see further improvements in the uranium market and contracting progress, as part of our commitment to providing a long-term sustainable source of nuclear fuel for our customers.
