The gold is found in a small quartz vein in crystalline limestone (dolomitic) not far from a contact with a dark Huronian rock, an outcrop of which can be seen about 300 yards northwest of the shaft house, near a little brook. There are streaks of mica in crystalline dolomitic marble.
schist (?) in the limestone near the vein, and actinolite is plentiful, as also is iron pyrite. The limestone also carries magnetite, often in well-formed octahedra. Small quantities of copper pyrite were also noticed. Some considerable masses of bismuthinite were obtained, and I heard with pain of larger pieces which had gone through the crusher as "lead." The hoistman, Michael Scullion, an unusually good observer, brought me small specimens of a mineral which I identified as native bismuth. Shows of gold
are frequently found in the quartz, to which the bismuth and bismuthinite seem also to be confined. One beautiful specimen of gold was in the form of wire and long flat fibres interlaminated with the green fibres of actinolite. As the actinolite is found mostly in the limestone, this brings the three minerals into close association. The assays show that the gold values extend somewhat into the highly mineralized lime stone, but the quartz forms the pay streak. Several specimens of arsenopyrite, copper pyrite and iron pyrite were brought in by the men for identification. (Ontario Bureau of Mines (1906) VOL.XV Part 1)
