Dec 07, 2005 (R Tuomi) - Grab sample BB-S1 from No. 1 shaft assayed 0.12 ounce gold per ton. Grab sample BB-S2 from No. 2 shaft assayed 1.29 ounce gold per ton.
Apr 15, 2020 (Therese Pettigrew) - The No. 1 shaft, located in mining location HW 748 on the north shore of Belmore Lake, was sunk on a quartz vein varying in width from 12 inches to 18 inches. The quartz vein striking approximately 165 degrees and dipping about 80 degrees to the west, occurs in a sheared, fine to medium-grained mafic to intermediate flow rocks. The quartz, occurring in the dump or muck pile from the No. 1 shaft, can be described as white, sugary, "bull" quartz. The quartz is mineralized with biotite and chlorite, some fuchsite, and sparse pyrite, with a few specks of chalcopyrite and pyrrhotite. A grab sample of quartz taken from the No. 1 shaft dump and assayed by the Geoscience Laboratories, Ontario Geological Survey, Toronto, yielded 0.12 ounces Au/ton, 110 ppm Cu, and 0.18 ounces of Ag/ton. A second shaft or very deep pit is located approximately 1000 feet NNE of the No.1 shaft. Grab samples of quartz and quartz-carbonate material collected at the No. 2 shaft or pit were mineralized with tourmaline, fuchsite and/or epidote and very sparse pyrite. The quartz is white and massive, and no visible gold was seen. The origin of the quartz and quartz-carbonate material at this shaft location is unknown as no quartz was seen in the excavation. A grab sample from this shaft location was assayed by the Geoscience Laboratories, Ontario Geological Survey and yielded 1.29 ounces Au/ton 40 ppm Cu, and 0.09 ounces Ag/ton (Janes and Speed, 1980).
