A northwest trending belt of Jurassic to Triassic metasediments and metavolcanics is intruded by a granitic to quartz diorite pluton of the Tertiary to Cretaceous Coast Plutonic Complex. The meta- volcanics, consisting of schists, lie west of a sheared contact with the granite.
Massive and disseminated molybdenite and minor pyrite occur along a 53 metre long, 0.6-2.1 metre wide shear zone in steeply dipping interbedded quartz-hornblende schist and impure micaceous quartzites. A 0.6 metre wide sample assayed 1.05 per cent MoS2 (Assessment Report 2706).
Scattered occurrences of mineralized quartz veins occur along a 1200 metre trend north of the above main showing. On the eastern shore of Porcher Inlet, about 2.3 kilometres northwest of the molybdenite showing is a one metre wide quartz band, within meta- sediments, containing irregular masses of chalcopyrite and bornite.
