Copper mineralization is exposed on Caledonian Creek, 650 metres north of the confluence with the Indian River, 19 kilometres southeast of Squamish.

A trench, on the east bank of Caledonian Creek, exposes pyrite and chalcopyrite(?). The mineralization is hosted in volcanics and sediments of the Upper Jurassic to Lower Cretaceous Gambier Group, near the south end of the Indian River roof pendant.
