The Kimo occurrence is located east of the Mahatta River, west of the community of Mahatta River.

The area lies within the Insular Belt of the Cordillera and is underlain mainly by volcanics, crystalline rocks and minor sediments. Andesitic to rhyodacitic lava, tuff and breccia of the Lower Jurassic Bonanza Group overlie an assemblage consisting of sediments of the Paleozoic Sicker Group and Upper Triassic Vancouver Group basalts and minor carbonate and clastic sediments. The Bonanza volcanics are coeval with, or genetically related to, granodiorite stocks of the Jurassic Island Plutonic Suite which intrude all older rocks in the area.

At the Wm occurrence chalcopyrite mineralization probably occurs in a quartz vein stockwork in Parson Bay Formation (Vancouver Group) carbonate clastics, near the contact with Bonanza Group volcanics.

The location, given in Minister of Mines Annual Report 1968 page 97, coincides with that of the Kimo occurrence (092L 291). Evidence of past exploration activity is reported here (Assessment Report 8018, Figure 1).

From 1979 to 1980, the area was originally staked as the Kimo 1-6 claims by W.G. Botel but evidence of older workings were present at this time. From 1988 to 1992, Electrum Resources completed programs of geological mapping, prospecting and geochemical sampling on the Kos claims.
