A 100 metre long magnetite ore zone, striking northwest and dipping 80 degrees east, lies concordant with bedding and schistosity of the Permian (?) or older schists. Coast Plutonic Complex rocks lie to the west.

The magnetite occurs as small discontinuous massive bands and irregular lenses up to 4.5 metres wide. A one metre wide sample assayed 68 per cent iron (Minister of Mines Annual Report 1930).
