The Locality 7 occurrence is underlain by basalt of the Upper Triassic Karmutsen Formation (Vancouver Group). A splay from the Marble Bay fault cuts through the area.
A shallow trench exposes basalt containing variable, locally abundant pyrite. A composite grab sample of pyrite-rich basalt assayed 89 parts per billion gold. A grab sample of pyritic basalt from a dump of a nearby pit, assayed 0.675 grams per tonne gold (Assessment Report 17947).
