Subject category Comment text
Deposit MANY QUARTZ VEINS, SOME ALONG FAULTS AND MOST OFFSET BY FAULTS, CONTAIN FREE GOLD AND SULFIDES INCLUDING STIBNITE, ARGENTIFEROUS GALENA, ARSENOPYRITE, PYRITE, AND SPHALERITE. SOME OXIDATION PRODUCTS. SOME SILICIFIED SCHIST BETWEEN VEINS MIGHT CONSTITUTE LOW GRADE GOLD ORE. CONSIDERABLE SURFACE ENRICHMENT IN PLACES. STIBNITE IN KIDNEYS AND IRREGULAR VEINS. GOLD CONTENT VARIABLE; HIGHEST WHERE SULFIDES ARE MOST ABUNDANT. HANGING WALL OF MAIN VEIN MARKED BY A FAULT; SOME OF SULFIDE MINERALIZATION WAS EARLIER THAN THE FAULTING.
