The Cigar Lake ore body was discovered in 1981. The first mine shaft was completed in 1990 to support underground exploration and testing of mining methods. Construction and development activities were disrupted by flooding in 2006 and 2008. Cameco has since successfully secured the mine and production began in 2014. The mine is located about 660 kilometers north of Saskatoon, Saskatchewan and is owned by Cameco. Cigar Lake is the world's second largest high-grade uranium deposit after Cameco's McArthur River and the ore is processed at the McClean Lake Mill. For more information, visit Cameco's website.

- public and worker radiation dose
- lost-time incidents for workers
- environmental monitoring results
- environmental reportable spills and corrective actions taken
- current financial guarantees for future decommissioning costs
