McArthur River is the world's largest, high-grade uranium mine, and Key Lake is the world's largest uranium mill. Ore grades at the McArthur River mine are 100 times the world average, which means it can produce more than 19 million pounds per year by mining only 150 to 200 tonnes of ore per day. We are the operator of both the mine and mill.
