Capsule Geology

The Milligan showing is located 5 kilometres south-southwest of Vernon, at the edge of Kalamalka Lake.

In this area, west of the Okanagan Valley fault zone, volcanic and sedimentary rocks of the Devonian to Triassic Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by the Jurassic Nelson Intrusions. Granitic Coryell rocks of Eocene age intrude these rocks.

A breccia zone in limestone, near the contact with Middle Jurassic granitic rocks, hosts gold mineralization. The zone, up to 60 metres thick and 150 metres high, contains quartz fragments and free gold. Gold values up to 5 grams per tonne are reported (Minister of Mines Annual Report 1902 p. 188).

The occurrence was first described in 1902. Development includes one small adit, trending west-northwest, about 200 metres north of the breccia zone and 100 metres west of the edge of the lake.
