May 28, 2020 (Therese Pettigrew) - Intermediate to felsic tuff with minor argillaceous and cherty sediments apparently lie near the top of a heterogeneous sequence of volcanics and sediments in the southern part of Labyrinth Bay (Davies, 1970). The area is structurally complex, and these north-facing rocks may be in fault contact with mafic and ultramafic sills to the north (Davies and Smith, 1988).

May 28, 2020 (Therese Pettigrew) - A 1.5 m wide, carbonate- and quartz-rich felsite dike occurs within a massive felsic tuff unit. About 9 m from the western shore of Island J.O. 154, a pit was sunk an estimated 3 m on the dike. Rock on the dump contains "considerable pyrite and a little marcasite or pyrrhotite.. ...It is reported that gold can be panned from the mineralized rock" (Davies, 1978).
