Metamorphic rocks consisting of quartz-feldspar chlorite gneiss, sericite chlorite phyllite, limestone and chlorite schist to greenstone of the Lower Cambrian part of the Eagle Bay Formation lie adjacent to the Cretaceous Baldy Batholith.
A pod of skarn, 18 by 9 metres, occurs within massive crystalline limestone. It consists of epidote, diopside, calcite, chlorite and garnet with minor pyrrhotite, pyrite and chalcopyrite. A sample assayed 0.14 per cent copper (Assessment Report 3430).
About 500 metres to the east, pods and lenses of pyrrhotite with minor pyrite and traces of chalcopyrite occur in highly fractured and sheared chlorite schist.
