Several quartz veins cut granodiorite of the Cretaceous to Tertiary Coast Plutonic Complex. The veins, which strike 150 degrees and dip vertical, are related to a north trending fault. Pyrite and scheelite occur as disseminations within the quartz veins. The highest assay was 0.06 per cent tungsten (Property File - Byers, 1942). The mineralized zone measures 250 by 30 metres.
