| Deposit | THE FIRST DISCOVERY IN THE DISTRICT IN 1891, WITH THE GREATEST PERIOD OF DEVELOPMENT AND PRODUCTIVITY BETWEEN 1893 AND 1905. EARLY PRODUCTION WAS OF FREE MINING AU-AG ORE FROM THE SHALLOW OXIDIZED ZONE. DEVELOPMENT WORK TOTALS NEARLY 5 MILES. THE MINES ARE EXTENSIVELY DEVELOPED BY TUNNELS AND DRIFTS THAT CUT AT LEAST 15 VEINS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV |
| Deposit | AT LEAST 15 VEINS. SULFIDES OCCUR IN QUARTZ VEINS CUTTING DIORITE. BIOTITE-BEARIG GRANITE PORPHYRY OCCURS ON THE DUMP, AND SOME SAM-PLES OF VEIN MATTER CONTAIN FRAGMENTS OF A GRANITE PORPHYRY WA-LL (?) MOST OF THE VEINS IN THE DISTRICT WERE REPORTED TO TREN-D NW TO NNW. SOME ROCKS ON THE DUMP ARE SILICIFIED. QUARTZ VEI-NS EXHIBIT SOME OPEN-SPACE TEXTURES. TOURMALINE MAY BE PRESENT- IN QUARTZ VEIN MATTER, AS WELL AS CALCITE. |
