Comment (Location): UTM ACC. LOCATION PROJECTED. LAND UNSURVEYED
Comment (Production): A SMALL AMOUNT OF ORE PRODUCED IN 1912 RAN 2.25% PB AND 14.0 OZ/TON AG. OWNER HAD FAIR RETURNS AND SOLD SPECIMENS OF COARSE GOLD. AVERAGE $9/TON.
Comment (Deposit): NUMBER OF SMALL VEINS, AVG. 2 - 3 IN. IN THICKNESS. ACCORDING TO OWNER, THICKER VEINS USUALLY BARREN. THEY STRIKE N 35 - 50 E AND ARE APPARENTLY BRANCHES OF MAIN VEIN, WHICH WAS TRACEABLE FOR A SHORT DISTANCE ON SURFACE. CALCITE STRINGERS JOIN VEIN AT ACUTE ANGLES AND ARE CONFINED TO FOOTWALL SIDE.
Comment (Workings): TUNNELS AND A SHAFT, MANY OOPEN CUTS AND TRENCHES
Comment (Geology): POST-MINERAL FAULTS OF SMALL DISPLACEMENT OFFSET VEINS IN MANY PLACES. HYPOGENE MINERALS, IN ORDER OF ABUNDANCE, INCLUDE: PYRRHOTITE, ARSENOPYRITE, CHALCOPYRITE, PYRITE, GOLD
