Capsule Geology

The region is underlain by an assemblage of sedimentary rocks consisting mainly of continental margin and shelf facies rocks. This assemblage was deposited on, and to the west of, the ancestral North American craton. These sedimentary rocks, for the most part typical miogeoclinal facies, range in age from Hadrynian to Upper Cretaceous. Structurally these rocks are part of the Foreland Thrust and Fold Belt of the North American Cordillera.

The Babette Lake prospect is underlain by quartzite of the Mahto Formation of the Lower Cambrian Gog Group. The formation, which is in excess of 213 metres thick, hosts high quality building stone within various stratigraphic intervals. The high quality intervals contain pink, purple, reddish, grey and white, thin bedded to massive, occasionally speckled quartzite that is weakly to moderately fractured. Intervening poorer quality beds are comprised of white, grey, pink, purple or variably coloured, massive to thin bedded, intensely to moderately fractured quartzite, which is commonly interbedded with shale or siltstone. Drilling perpendicular to bedding encountered six sections of the high quality material, at or near surface, ranging from 7.6 to 38.7 metres thick. Four sections are at least 18.3 metres thick.

Babette Lake Quartzite Products Ltd. conducted 276 metres of drilling in 3 holes in 1981. Several kilometres to the south, near Wishaw Lake, a test quarry, in a similar occurrence, was developed (093H 131).
