Peter Dasler reports that CanAlaska Uranium Ltd. is pleased to report that it has acquired by staking approximately 75 kimberlite targets in the Western Athabasca Basin, Saskatchewan. The claims staked by CanAlaska cover kimberlite style targets developed from a high-resolution airborne geophysical survey carried out on behalf of the Saskatchewan Geological Survey.

The 2011 airborne magnetic survey reveals a series of discrete magnetic anomalies with a shallow signature northeast of the Carswell structure and close to a large crustal structure, the Grease River Shear Zone. The Saskatchewan Kimberlite Indicator Mineral sampling (KIM) programs reached close to the Carswell structure, but the most northern samples remain southeast of the down-ice trend from these magnetic anomalies.

There is has been no known kimberlite exploration in the Athabasca Basin and limited general exploration in the project area. The Fort McKay-Fort McMurray KIM trend in Alberta is dominated by chromite, but contains also some pyrope and eclogitic garnets. These appear to be down-ice from the targets identified by CanAlaska in the northwestern Athabasca within the Athabasca sandstone. The basement rocks below the Athabasca sandstone in the project area are classified as Rae Province. The Rae Province rocks host diamondiferous kimberlites in Nunavut. The Buffalo Hills and the Birch Mountain kimberlite fields in Alberta appear to lie on the same structural trend as the project area.

They have some distance to go to establish whether these targets are kimberlites, and then whether they contain diamonds, but they are very encouraged by large number of distinct targets and the existence of indicator minerals to the southwest.
