DISCOVERED:

1979 by the Canadian Oxy - INCO Joint Venture

OPERATION:

McClean Lake has the newest and most technologically advanced uranium mill in the world. The operation began producing yellowcake in 1999 using ore from the now completed JEB, Sue C, Sue A, Sue E and Sue B open pit mines. The JEB pit has now been converted into a tailings management facility. In 2001, McClean Lake received ISO 14001 environmental management certification. In 2008, McClean Lake became the first uranium mine in North America to obtain OHSAS 18001 international health and safety management certification.

CAPACITY:

Initially 6 million lbs. U₃O₈; annual licensed capacity increased to 8 million lbs. U₃O₈ (3,077 tonnes uranium) in 2001. 

PRODUCTION:

1.7 million lbs. U₃O₈ (1,384 tonnes uranium)

RESERVES:

2.7 million lbs. U₃O₈ (1,040 tonnes uranium) stockpiled with an average grade of 0.62% U₃O₈

RESOURCES:

16.03 million lbs. U₃O₈ (5,900 tonnes uranium) with an average grade of 2.2% U₃O₈

PLANS FOR 2011:

• Mill has been put into a care and maintenance mode as of June 2010.
• Continue with the regulatory process to bring a portion of the ore slurry from McArthur River to McClean Lake to commission the mill.
• The mill's re-start date will depend on market conditions, the Cigar Lake mine schedule, and the availability of ore from McArthur River.
• Continue to work to secure tailings management capacity for the next decades.
• An underground mine is in the planning stage.
