Sediments and volcanics of the Cretaceous Age Gambier Group have been intruded by quartz diorite of the Coast Plutonic Complex. At the showing a section of limestone, limy siltstone and argillite or horn- felsic sediments is situated within an embayment in the quartz diorite. A skarn zone that is characterized by minerals such as quartz, garnet, epidote, chlorite, specular hematite and calcite has formed along part of the contact. Also occurring in the skarn zone are minor to trace amounts of chalcopyrite, bornite, malachite, azurite, molybdenite, scheelite and galena.
