The area is underlain by Lower Cambrian rocks of the Eagle Bay Formation consisting of siliceous and graphitic phyllites, phyllitic limestones and greenschist. The metavolcanics and meta- sediments generally strike northeast and dip 10 to 40 degrees northwest. The rocks are cut by Late Cretaceous or Early Tertiary quartz-feldspar porphyry and mafic dykes with northerly trends.

The ORO showing occurs within thinly bedded light and dark argillaceous phyllites cut by andesite and hornblende porphyry dykes.

Mineralization consists of disseminated and veinlets of pyrite, pyrrhotite and chalcopyrite with very minor sphalerite in a drill hole.
