Disseminated, stringers and massive sulphide mineralization is associated with quartz gangue within lensoidal masses or shoots along the shear zone known as the Black Bluff fault. The fault is interpreted as a thrust zone with Lower to Middle Ordovician black and graphitic argillites of the Active Formation to the west and upper Laib Formation phyllites, argillites, quartzites and minor limestones to the east.
Sulphides include pyrite, sphalerite and galena within quartz zones of highly variable width and extent although the mineralization appears related to disconnected shoots rather than to well defined planar structures. A 4.5-metre thick lens containing 1.8 metres of latite dyke on the hanging wall assayed 2.74 grams per tonne gold, 442.3 grams per tonne silver, 21.6 per cent lead and 1.3 per cent zinc (Geological Survey of Canada, Memoir 172, page 82). Minor production was carried out in the 1920's of hand sorted ores.
Sultan Minerals Inc. located a large zinc, silver and copper soil anomaly on the north area of Wilson Creek in 1997.
