The Jean (North Shore) occurrence is located near the north shore of Nahwitti Lake, approximately 1.5 kilometres east of the lake’s western end.
Regionally, the area is underlain by northwest-trending belts of basaltic volcanics and carbonate sedimentary rocks of the Upper Triassic Karmutsen and Quatsino formations (Vancouver Group) and mafic volcanics and sediments of the Upper Triassic to Lower Jurassic Bonanza Group (Holberg volcanic unit, Nahwitti River wacke and Parson Bay Formation). These volcanic and sedimentary rocks have been intruded by granodioritic rocks of the Early to Middle Jurassic Island Plutonic Suite.
Locally, Quatsino limestone and Karmutsen volcanics are in contact with monzonite of the Island Plutonic Suite. A stringer of sphalerite-galena mineralization, up to 35 centimetres wide, occurs in silicified limestone (skarn?). An area of monzonite is present to the east. Related mineralization is located 1250 metres to the west at the North Shore (MINFILE 092L 077) occurrence.
In 1966, Giant Explorations Ltd. completed a program of geological mapping and geochemical sampling on the area as the HPH claims. In 1968, Kodiak Mines completed a program of prospecting, geochemical sampling, geological mapping and a 50.0 line-kilometre ground magnetic survey on the area as the Jean, Lake, Ken and FTR claims. In 1976, Rio Tinto Canadian Exploration Ltd. completed a 1.0 line-kilometre induced polarization survey on the Lake and Jean claims.
In 1988, QPX Minerals Inc. completed a program of rock sampling and geological mapping on the area immediately west. In 1991, Universal Trident Industries Ltd. prospected and sampled the area immediately north as the Witti 1-3 claims.
