The area is underlain largely by Lower Cambrian metamorphic rocks of the Eagle Bay Formation in contact with the Cretaceous Baldy Batholith. Four distinct units include quartz-feldspar chlorite gneiss, sericite chlorite phyllite, limestone and green chlorite schist to massive greenstone. All units normally strike northeast and dip northwest at moderate angles. Major north trend- ing and minor northwest trending faults displace the units.

Copper mineralization, with accompanying silicification, pyritization and potassium feldspar alteration, occurs in the stratigraphically lower zone of the chlorite schist to greenstone unit, just east of its faulted contact with the intrusive. Chalco- pyrite, pyrite and lesser pyrolusite, pyrrhotite, bornite and covellite occur as disseminations and fracture fills in largely brecciated and sheared host rocks. Seven showings occur within a 650 by 250 metre area. A 2.4 metre chip sample of showing #1 assayed 0.72 per cent copper (Assessment Report 3430).
