Mar 30, 2022 (Therese Pettigrew) - The quarry is in a grey medium-grained biotite granitoid rock, which is massive in the vicinity of the workings. Predominant joint sets are oriented 000-020 degrees / 85 degrees W and 100/85 degrees N. The joints are spaced approximately 1 to 1.5 m apart. Sheeting varies from 1.3 m at the west end of the workings to 3 m at the east end of the workings. The quarry was developed along a south facing ridge for a distance of approximately 30 m. The rock was often removed using the joints to outline the blocks. Modal analysis of a sample taken from the old workings indicates that the rock has a granodiorite composition. The material sampled has a relatively high biotite content, some of which plucked out during polishing (Storey, 1986). The following is from Lawson (1886): "A boss of coarse-grained, grey, granitoid gneiss, considerably crushed and altered projects through the schists on Quarry Island and on the opposite shore. The vein on which the Sultana Mine is situated, occurs in this rock, and a number of other gold locations have been taken up in its neighbourhood. Small veins of quartz carrying molybdenite traverse the gneiss in places, and larger veins of molybdenite have been found in the country between Quarry island and Rossland. A quarry has been opened on the island for material for bridge piers, and the gneiss or 'granite,' as it is called, is found to furnish excellent blocks for heavy masonry."
