Deposit AURIFEROUS QUARTZ REEFS. VEINS ARE 1-2 M WIDE, ARE GENERALLY CONFORMABLE WITH THE LOCAL SEQUENCE, AND CONTAIN VISIBLE GOLD. LODE SYSTEMS CONTAIN VERY FINE SOMEWHAT DISSEMINATED GOLD AND ARE FOUND IN THE CROSSCUTTING SHEAR ZONES 5-20 M WIDE. BELOW 50 M (THE THICKNESS OF OXIDATION) THE ORE CONTAINS ABUNDANT VISIBLE SULFIDES. THE PRIMARY ORE CONSISTS OF MINUTE INCLUSIONS OF GOLD WITHIN ARSENOPYRITE AND STIBNITE.
