Cigar Lake Mine
Saskatchewan, Canada
The Cigar Lake Mine is a large high-grade underground uranium mine, located in the uranium-rich Athabasca Basin of northern Saskatchewan, Canada, at the south-west corner of Waterbury Lake. The deposit, discovered in 1981, is second in size of high-grade deposits only to the nearby McArthur River mine. Other deposits, such as the Olympic Dam mine in Australia, contain more uranium but at lower grades.
