Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The island on which this occurence is located lies on the southwest corner of the Dome Stock. The occurrence is primarily underlain by intrusive augite diorite, with minor amounts of metadacite tuff. Lamprophyre dikes are quite common in the area. The diorite is fine to medium grained, generally quite massive, with minor disseminated pyrite in weakly foliated sections. The metadacite tuff is strongly foliated parallel to bedding, fine to medium grained, and contains numerous quartz and carbonate stringers. DEPOSIT DESCRIPTION: A shear zone exists on the northern tip of the island. It occurs in a metadacite tuff and contains numerous white carbonate and quartz stringers. The stringers are up to 2 mm in width and occur over a 2 m width. Pyrite, pyrrohtite and minor magnetite are found in the zone.
