AREVA operates McClean Lake and is a 70% owner alongside Denison Mines Corp., which has a 22.5% stake, and Overseas Uranium Resources Development (OURD) Company Ltd of Japan, which owns 7.5%.

The McClean Lake mill is the only mill in the world able to process very high-grade ore without dilution, AREVA said. It will eventually have a production capacity of 10,900 tonnes of uranium concentrate per year.
