Cigar湖铀矿床位于加拿大萨斯喀彻温省的北部。经过数年钻探,已经证实它的主矿体储量为2.85亿磅U_3O_8(13万吨U_3O_8),矿体品位为4.7%U_3O_8。发现该矿和负责勘探的加拿大Cogema公司宣称,上述储量为地质储量,可采储量的大小与所选择的开采方法有关。随着勘探的进展,该矿床的储量增加很快。83年为1.25亿磅U_3O_8(约为5.7万吨U_3O_8),84年为2.3 The Cigar Lake uranium deposit is located north of Saskatchewan, Canada. After several years of drilling, it has proven its main ore body reserves of 285 million pounds U_3O_8 (130,000 tons of U_3O_8), ore grade 4.7% U_3O_8. Found that the mine and Cogema Inc. of Canada, which is responsible for exploration, claimed that the above reserves were geological reserves and the recoverable reserves were related to the mining method of choice. As the exploration progresses, the reserves of the deposit increase rapidly. 83 billion pounds of U_3O_8 (about 57,000 tons of U_3O_8) in 83 years and 2.3 in 84 years
