Despite multiple setbacks, Cigar Lake mine began production in early 2014, using the jet-boring technique pioneered by Cameco specifically for its challenging geology. The mine has now produced 150 million pounds of uranium concentrate. “Looking back, there were times of uncertainty and sleepless nights wondering if we could make the machine perform as designed. Fortunately, we had an amazing team of professionals from many different backgrounds who persevered and made the JBS what it is today,” mine general supervisor Dylan Probert says.
