The East Side showing of the Cole property area is underlain by a sequence of volcanic and sedimentary rocks of the Lower Jurassic Telkwa Formation of the Hazelton Group. Host rocks consist of thick-bedded purple to green lapilli tuffs and volcanic breccias dip steeply northwest and are commonly cross-cut by intermediate dikes. Black mudstone and siltstone occur in the vicinity.

The East Side showing is associated with a northwest trending system of veins that contains both northwest trending veins and north to northeast trending veins. It is an acutely branching array of veins that split, splay and horsetail. It is an acutely branching array of veins that split, splay and horsetail. The individual veins are associated with minor shears and pinch and swell from stringer-stockworks to masses up to and in excess of 3 metres width. Veins dip steep (60 degrees) to vertical. The overall mineralized vein system is traceable intermittently for in excess of 4 kilometres. Vein quartz types include massive, banded, vuggy and coxcomb quartz generally white in colour but locally beige, grey, clear, red and rarely amethystine. At least 10 discrete zones or showings have been documented and sampled over part of the 4 kilometre length. Most of the showings are low in sulphides containing less than 1 per cent pyrite, locally to 15 per cent.

Discovered in 1983 during reconnaissance coverage of this portion of the claims, the East Side gave a value of 1.58 grams per tonne gold (Assessment Report 14531). Follow-up in 1984 verified the earlier anomaly with the discovery of values up to 4.1 grams per tonne gold (Assessment Report 14531). Mineralization appears to be associated with quartz stringers and veins (to 1 metre) and pyritic-rusty propylitized and bleached volcanics. Minor galena occurs with this system.
