The project comprises 2,685 hectares and is located 10km west of the Millennium deposit and some 50km NNW of the Key Lake mine and 50km southwest of the McArthur River mine.
Basement rocks comprise Archean granitoids and Lower Proterozoic (Trans-Hudson) metamorphic rocks of the Wollaston and Mudjatik domains. These are unconformably overlain by an estimated 600-750 metres of flat-lying Athabasca sandstones and conglomerates. The basement rocks are composed of supercrustals (psammites, pelites, and calcsilicates with minor greenstones) and Archean granitic gneisses. An interpretation of aeromagnetic maps suggests a series of domes and basins in the basement rocks trending northwest to southeast with bordering graphitic conductors.
Historical work includes airborne and ground geophysics, lithogeochemical surveys and lake sediment surveys by Denison and SMDC. Work has been concentrated primarily in the southern and eastern areas of the project.
CanAlaska carried out initial VTEM airborne surveys over a larger claim area, and followed up with ground sampling and rock geochemistry. A very well defined conductive target appears within the centre of the property. Published data shows that the UTEM conductors successfully drilled by Kodiak Exploration at their adjoining West Millennium property extend onto the McTavish Project and appear to intensify. Previously announced Kodiak drill hole WM09-04, which intersected a 69 metre thick fractured graphitic and pyritic pelite unit with uranium mineralisation is located only 400 metres from the McTavish property. This drill hole indicates that the project is in a generally favourable environment. UTEM data also defines two other large scale, high magnitude conductors on the McTavish property. The project was under option to Kodiak for one year and they carried out a ZTEM survey across the property, and followed up with two drill holes. Both of these holes intersected basement granite, rather than the interpreted graphitic conductors.
The potential of this project is for unconformity style Uranium mineralisation of both the Simple (Low REE, basement hosted) and the Complex (High REE, Sandstone hosted) types of Uranium deposit. The structural offsets, and associated uranium mineralisation in the nearby drill holes, indicate that the graphitic conductor flexes as it crosses the property and has potential to host uranium mineralisation.
