The area is underlain by metavolcanics and metasediments of the Devonian to Mississippian Eagle Bay Formation. Copper mineralization occurs in quartz-sericite phyllite derived largely from felsic to intermediate volcanics. Other rock units include chloritic phyllite, dark grey graphitic phyllite, quartz-sericite schist, sericitic quartzite and chert. The strata strikes northeast and dips gently to the north. A north northeast trending fault separates quartz- feldspar augen gneiss to the east.

Chalcopyrite, pyrite and minor pyrrhotite occurs as dissemina- tions along foliation planes and fractures. Low grade mineraliza- tion occurs over about 500 metres, with selected trench samples assaying up to 0.43 per cent copper.
