Location 

This project is a contiguous block of 5 mineral claims totaling 24,285 ha located 30 km west of the McArthur River mine and 30 to 50 km north of the south rim of the Athabasca basin. The claims trend northwest and adjoin both CanAlaska's West McArthur and McTavish projects. 

Geology

The project group straddles the boundary between the Mudjatik and the Wollaston domains. Basement rocks comprising of Archean granitoids and Lower Proterozoic (Trans Hudson) metamorphic rocks are unconformably overlain by 700 to 900 metres of flat-lying Athabasca sandstones. An interpretation of aeromagnetic maps suggest a succession of domes and basins in the basement rocks trending NW-SE.

Exploration

Previous work included airborne and ground geophysics, lithogeochemical surveys and lake sediment sampling by Kerr-Addison and later by Cogema. Work has been concentrated in the southern part of the property, while the northern areas have no known work.
In winter 2004-5 Canalaska flew the first deep penetrating MegaTEM surveys across the property. This was followed up in summer 2006. A Geotech V-TEM survey was completed and ground-based sampling and lake sediment analysis was performed. The Company identified zones of anomalous conductivity, suggestive of alteration zones in the sandstone. More detailed geophysical work within the target areas is required to define specific drill locations.

Potential

The potential of this project is for unconformity style U mineralization of both the Simple (Low REE, basement hosted) and the Complex (High REE, Sandstone hosted) types of Uranium. The McArthur River deposit has proven the fertility of the basin at depth, and with modern exploration technology the great depths which previously hindered geophysical exploration are no longer an issue. Significant conductors from the West McArthur project continue onto the Arnold project area.
