The Aban occurrence is located in the northern headwaters of the north arm of the Goodspeed River, approximately 2.5 kilometres west-northwest of the western end of Nahwitti Lake.
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, a skarn zone in limestone, probably of the Quatsino Formation, is mineralized with sphalerite and galena. The mineralization is reported to be similar to the South Shore (MINFILE 092L 074) occurrence.
In 1966, chip sampling is reported to have yielded up to 2.78 per cent zinc, 0.36 per cent lead and 2.06 grams per tonne silver over 3.05 metres and 1.81 per cent zinc, 0.97 per cent lead and 2.06 grams per tonne silver over 2.4 metres (Assessment Report 870).
In 1989, a chip sample (109495) of highly siliceous and fractured sediments assayed 0.306 per cent copper, 25.7 grams per tonne silver and 0.28 gram per tonne gold over 1.0 metre (Assessment Report 19769).
In 1966, Giant Explorations Ltd. completed a program of geological mapping and geochemical sampling on the area as the HPH claims. During 1968 through 1976, Acheron Resources completed intermittent programs of geochemical and geophysical surveys, hand trenching and geological mapping on the area as the TI, Mo, Mon and Bud claims.
In 1983 and 1984, Trawler Petroleum Explorations Ltd. completed programs of rock and soil sampling and geological mapping on the area as the Stump claim. In 1989, Mishibishu Gold Corp. completed a program of geological mapping and geochemical sampling on the area as the Win 1 and Helper claims. Also, at this time Essex Resources Corp. completed a program of geochemical sampling, geological mapping, 17.5 line-kilometres of ground geophysical surveys and trenching on the area.
In 1991 and 1992, Great Western Gold Corp. completed a program of line cutting, 7.5 line-kilometres of combined ground geophysical surveys and six diamond drill holes, totalling 502.3 metres, on the area.
