The area is underlain by the Lower Cambrian part of the Eagle Bay Formation consisting of siliceous and graphitic phyllites, phyllitic limestones and greenschist. The metavolcanics and metasediments 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.

Several thin and discontinuous zones of massive sulphides are concordant with the metavolcanics and metasediments.

A sample of one zone assayed 6.37 per cent zinc, 0.5 per cent lead, 0.13 per cent copper and high values for gold and silver (Assessment Report 13514).
