Comments
Comment (Workings): INCLINED SHAFT, DRIFTS, "GLORY HOLE" PIT. WORKINGS FLOODED BELOW 220 FT. GLORY HOLE ON TOP OF RIDGE.
Comment (Location): MAIN SHAFT ON E SIDE OF RIDE.
Comment (Production): "CONSIDERABLE" ORE PRODUCED, BUT NOT PROFITABLE DUE TO LOW RECOVERY IN MILLING. PRODUCTION YEARS 1893-1903. ORE MILLED AT SMALL MILL AT MINE SITE
Comment (Deposit): RICH ORE OCCURS IN STREAKS AND BUNCHES. THE VEIN IS MADE UP OF 2 PARALLEL 20 IN LAYERS. BETWEEN THEM IS ALTERED GRANITE WITH QUARTZ STRINGERS.
