Deposit 2 VEIN SYSTEMS. PRINCIPAL ORE SHOOT PITCHES N18E, BEING BOUNDED BY FAULT. NORTH ORE SHOOT YIELDED MOST GOLD, EXTENDED FROM NEAR SURFACE TO 210 FT. LEVEL OF WORKINGS. IT WAS 132 FT. IN AVG. STOPE LENGTH, AVG. 6 FT. THICK. COARSE PYRITE APPEARED IN PATCHES; CARRIED SMALL AMOUNT OF COPPER SULFIDES. NEARLY ALL GOLD WAS IN SULFIDES, WHILE QUARTZ WITH LITTLE OR NO SULFIDE WAS LOW-GRADE. SOUTH ORE SHOOT APEXED ABOUT 210 FT. ADIT LEVEL AND HAD PITCH LENGTH OF 140 FT., STOPE LENGTH AVG. 110 FT. BETTER ORE OCCURED IN FLATTER-DIPPING VEINS. MORE DETAILED DESCRIPTIONS IN OBRIEN (1940).
