The Berg 16 occurrence is located on an un-named northeast-flowing tributary of the Nahwitti River, approximately 10 kilometres north-northeast of the community of Holberg.

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, Karmutsen Formation andesites containing two narrow bands of limestone near the top of the unit are overlain by Quatsino Formation limestone. Younger Bonanza Group volcanics are found to the west and southwest. Skarn is found near the top of the Karmutsen rocks, where minor chalcopyrite occurs with massive magnetite. In the Quatsino limestone, minor pyrite and chalcopyrite have been noted close to intrusive contacts (Island Plutonic Suite?). Disseminated pyrite is present in one of the Karmutsen limestone bands. Oxidation of chalcopyrite to malachite is common.

In 1989, a rock sample (33068) of magnetite from epidote limonitic skarn assayed 0.209 per cent copper (Assessment Report 19190).

During 1968 through 1970, Continental Cinch Mines Ltd. completed programs of prospecting, soil sampling, geological mapping and a 16.0 line-kilometre ground magnetic survey on the area as the Berg 1-178 and B 1-12 claims. In 1989, Mishibishu Gold Corp. completed a program of geological mapping and geochemical sampling on the area as the Nahwitti 1-4 claims.
