The Kains occurrence is located near the southern end of Kains Peninsula, approximately 6.5 kilometres south of Winter Harbour.

The area is underlain by sediments and volcanics of the Lower Jurassic Bonanza Group.

The showing consists of disseminated pyrite and small lenses of chalcopyrite associated with a shear zone within Lower Jurassic Bonanza Group andesites. Mineralization has been traced over 60 metres. The andesites are strongly chloritized and are cut by a quartz-diorite dike, 1.5 to 2.0 metres in width, which strikes northeast, parallel to the mineralized shear zone.

In 1969, Utah Construction and Mining Co. completed a program of geological mapping and geochemical sampling on the Kains claims.
