Capsule Geology

The Big Rock zone of the Inel property occurs in an area that is primarily underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. Lower Jurassic andesitic volcanics of the Hazeleton Group overlie the Stuhini rocks and Early Jurassic feldspar porphyritic rock and monzodioritic to gabbroic rock intrude the strata.

The Big Rock showing was located in 1984 by Skyline Explorations. Trenching and mapping exposed at least one massive sulphide lens localized at the contact with the main alaskite pluton and hosting sediments of the Lower Jurassic Unuk River Formation. Sulphides include pyrite, chalcopyrite, sphalerite and galena with reported high grade silver assays (Property File, Grove, 1987).

See Inel (104B 113) for details of related mineralization and work history.
