The world's second-highest grade uranium deposit, Cigar Lake is located 450 meters below the surface, in porous, waterlogged rocks. Orano discovered the deposit in 1981 and has contributed to developing an innovative mining method there: the Jet Boring system, a drilling process combining land reinforcement by freezing and high-pressure water mining of ore.
Production (100%) in 2017: 6 925 tonnes of uranium
Average grade per tonne of ore in 2016: 126 kg
New deposits to sustain the McClean Lake mill
In Canada, Orano is continuing its exploration efforts, focusing on the most economical new sites. This is the case in the Athabasca Basin, a region with high potential that could supply the McClean Lake plant and increase the volume of reserves, giving its customers visibility over the next 20 years of production.
