URANIUM 101
The largest and highest grade deposits in the world are at the Unconformity

Athabasca Unconformity Uranium Deposits

The largest and highest grade deposits in the world are at the Unconformity or in highly altered sediments just above it with a distinctive signatures extending vertically hundreds of metres to surface.

The major known uranium deposits are associated with often graphitic structures in the basement gneiss straddling the unconformity with the overlying sedimentary basin.

The Company’s exploration strategy is based on discovery of  Tier 1 deposits like McArthur River and Cigar Lake in unconformity or sediment hosted settings under cover.

The Athabasca Basin Major Known Uranium Deposits Dsicovery Over Time

The region hosts some of the highest grade and lowest cost uranium deposits in the world including renowned projects, such as Cigar Lake, McArthur River, Arrow, Triple R, Millennium and Wheeler River. There have been no major discoveries of the Cigar Lake or McArthur River type deep under cover since the 1980’s.

THE ATHABASCA BASIN has the largest and highest-grade URANIUM DEPOSITS in the world
