The Kimo occurrence is located east of the Mahatta River, west of the community of Mahatta River.
The area is underlain by calcareous siltstone, shale, limestone, greywacke, conglomerate and breccia of the Upper Triassic Vancouver Group Parson Bay Formation. Conformably overlying the Parson Bay sediments are andesitic to rhyodacitic volcanics of the Lower Jurassic Bonanza Group (Geological Survey of Canada Map 4-1974).
Locally, basalts are overlain by northwest striking, 40 degrees west dipping black calcareous sediments and feldspathic tuffs. Quartz-calcite veinlets, occur mainly in tuffs, and contain pyrite, chalcopyrite and sphalerite.
The host rocks are believed to be either part of the Parson Bay Formation (Vancouver Group) or the Bonanza Group. The occurrence may coincide with the Wm showing (092L 238).
From 1979 to 1980, the area was staked as the Kimo 1-6 claims by W.G. Botel, but evidence of older workings were present at this time. In 1980, sampling of past drill cores returned values up to 11,800 parts per million zinc, 70 parts per million lead, 202 parts per million copper and 300 parts per million molybdenum. A surface sample, taken at the same time, returned values of 6,980 parts per million zinc and 960 parts per million copper (Assessment Report 8018). From 1988 to 1992, Electrum Resources completed programs of geological mapping, prospecting and geochemical sampling on the Kos claims.
