Capsule Geology

The Cathy copper-chromite showing is 400 metres southeast of the Tulameen River, 950 metres south-southwest of the mouth of Britton (Eagle) Creek and 11 kilometres west-southwest of the town of Tulameen.

This occurrence is hosted in peridotite of the Early Jurassic Tulameen Ultramafic Complex, a zoned Alaskan-type intrusive complex. The showing lies in a northwest trending band of olivine clinopyroxenite with minor peridotite that flanks the southwestern margin of the dunite-rich core of the complex.

A small zone of disseminated chalcopyrite and chromite occurs in mildly tremolite-altered peridotite. A grab sample assayed 0.21 per cent copper, 0.17 grams per tonne platinum and 0.12 grams per tonne palladium (Assessment Report 2274, page 16).
