The Contact occurrence is located on a south-facing slope, northwest of the Zeballos River and east of Lime Creek.

The area of the occurrence is underlain by Lower Jurassic Bonanza Group massive and amygdaloidal andesite and agglomeratic andesite in contact with Upper Triassic Quatsino Formation limestone of the Vancouver Group. The hornblende diorite Zeballos phase of the Jurassic Island Plutonic Suite lies 2 kilometres west. Hornblende diorite dikes and aphanitic light-coloured aplite dikes occur in the area of the claims. The Eocene quartz diorite South Zeballos pluton lies 2 kilometres to the south but mineralization is not believed to be related to it.

Locally, a 1-metre-wide patchy magnetite band with minor associated chalcopyrite is contained within a 2-to 3-metre-wide garnet skarn at a limestone-porphyritic andesite contact. The mineralization follows a 310-degree–striking, 20-degree-southwest–dipping shear zone.

Work History

In 1961, BHP-Utah Mines completed a program of geological mapping and a 17.6 line-kilometre ground magnetic survey on the area as the Contact claim.

In 1999, E. Skoda of the Zeballos Mining Company prospected the area as the Zeb Au claim.
