The Raven (North Shore) occurrence is located near the north shore of Nahwitti Lake, approximately 1-kilometre east- northeast 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 and felsic dikes of the Island Plutonic Suite. A skarn zone, associated with a felsic dike, has been traced for approximately 150 metres to the northeast. The skarn consists of epidote, garnet and diopside, mineralized with magnetite and chalcopyrite.

In 1988, a sample (NLR88-074) from the Raven zone assayed 4.39 per cent copper, 0.11 per cent zinc, 0.075 per cent cobalt and 30.9 grams per tonne silver (Assessment Report 18502).

In 1965, Silver Standard Mines Ltd. completed a program of geological mapping and a ground magnetometer survey on the area. In 1966, Falconbridge Nickel optioned the property and completed a program of geological mapping, soil sampling, ground geophysical surveys and 59 metres of packsack drilling. Also 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. A minor amount of diamond drilling was also reported on the Raven zone in 1968 and 1971. 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. In 1991, Universal Trident Industries Ltd. prospected and sampled the area immediately north as the Witti 1-3 claims.
