Capsule Geology

The area of the Basement West showing is underlain by Devonian to Upper Triassic and older metasediments of the Icefield Ranges Assemblage.

The showing is a vertical, resistant, north-trending, coarse grained, massive to semi-massive sulphide lens up to 5 metres thick. The massive sulphide is predominantly pyrrhotite with lesser chalcopyrite and pyrite. The lens is interbedded with chlorite schist, mafic sills and limestone. A grab sample assayed 0.59 per cent copper (Open File 1993-13).
