Jan 14, 2020 (Therese Pettigrew) - Fine-grained metabasalt and medium- to coarse-grained metagabbro are the principal rock types on the island; they are complexly mixed and may reflect intrusion along a zone of parallel shears. Basalt inclusions occur in the gabbro in places. A narrow band of cherty metasediments lies close to the east side of the island and northeast-plunging Z dragfolds sere noted in one outcrop. Fine grained granodiorite dikes cut all the other rocks (Davies, 1978).

Jan 14, 2020 (Therese Pettigrew) - Pyrite and pyrrhotite, with traces of chalcopyrite, occur in some massive metabasalt and in fractures in the cherty metasediments. Sulphides appear to be most abundant along shear zones. Near the northwest corner of the island a slight positive dimethyl gyloxine field test for nickel was obtained the writer on a grab sample from a 100 foot (30 m) wide shear zone (Davies, 1978). No assays have been reported.
