Report: Grubstake A caved adit investigates a vein of fine-grained quartz and minor pyrite that strikes N60E and dips 77SE within unaltered quartz monzonite. Loen and Pearson (1989) stated that gold, silver, copper, and lead were produced. The dump is located within a wetland, but is composed of unaltered quartz monzonite; a sample contained 0.016 oz/ton gold, 0.11 oz/ton silver, 0.018% copper, 0.178% lead, and 0.004% zinc. Another sample, BJGS-2, Finn cabin location, contained 0.014 oz/ton gold, 0.18 oz/ton silver, 0.012% copper, 0.08% lead, 0.037% zinc, and 0.45% arsenic.
