Geologic setting

Geologic description

This deposit consists of chalcopyrite, galena, and sphalerite hosted in quartz-muscovite-chlorite schist; massive greenstone; intercalated phyllite, limestone, and quartz-muscovite schist; and calcareous schist. The ore minerals and host rocks lie on the south limb of the Kalurivik Arch. Protoliths for the host rocks are interpreted to be Devonian volcanic flows and tuffs intercalated with clastic and chemical sedimentary rocks (unpublished Noranda Report, 1975).
