Comments on the production information

  • PRODUCTION ESTIMATED AT MINIMUM OF $31,000 (PRIOR TO 1903). CUMMULATIVE PRODUCTION WORTH $10-15 PER TON. A SHIPMENT FROM THE SHAFT ASSAYED $660 PER TON

Comments on the workings information

  • DEVELOPED BY AT LEAST 3 SHAFTS AND AN OPEN PIT. (GLORY HOLE) ABOUT 100 FT BY 30 FT BY 25-30 FT DEEP, AND SEVERAL ADITS DRIVEN TO INTERSECT THE VEIN AT DEPTH. (GLORY HOLE) ABOUT 100 FT BY 30 FT BY 25-30 FT DEEP, AND SEVERAL ADITS DRIVEN TO INTERSECT THE VEIN AT DEPTH.

Comments on development

  • VEIN IS HEAVILY PROSPECTED BOTH NORTH AND SOUTH OF THE GLORY HOLE. OPEN TRENCHING AND RECENT EXCAVATIONS (INCLUDING DRILL ROADS) SURROUND THE GLORY HOLE. PROPERTY HAS BEEN EXTENSIVELY DRILLED ON 10-FT INTERVALS PROBABLY ABOUT 2-4 YEARS AGO BOTH ABOVE AND BELOW GLORY HOLE. NO ACTIVITY AT TIME OF EXAMINATION, BUT AREA IS STAKED AND PROBABLY ACTIVE INTERMITTENTLY (1983).

Subject category Comment text
Deposit SNOWFLAKE VEIN IS THE LARGEST VEIN SYSTEM IN THE AREA. IT FORMS A BOLD, WHITE, RESISTANT OUTCROP AND IS COMPOSED OF SEVERAL SUB-PARALLEL VEINS OF MAINLY QUARTZ, MASSIVE AND VUGGY IN APPEARANCE WITH INTRALENSES OF CALCITE AND QUARTZ AFTER CALCITE. A PORTION OF THE VEIN CONSISTS OF HEAVILY STOCKWORKED (QUARTZ) WALLROCK WITH VEINLETS GENERALLY LESS THAN 1 IN WIDE AND OCCASIONALLY GREATER THAN 6 IN, WHICH CROSSCUT EACH OTHER AND ALSO CROSSCUT THE MAIN VEIN TREND. BANDED VEINS OF QUARTZ AFTER CALCITE AND/OR SIDERITE CROSSCUT MAIN VEIN AT A HIGH ANGLE. OTHER QUARTZ VEINS IN WALLROCK ARE TRUNCATED BY MAIN VEIN, AND ALTERED ANDESITE FRAGMENTS CAUGHT UP IN VEIN SHOW FINE STOCKWORKS OF QUARTZ. IN ADDITION TO MASSIVE AND PRISMATIC QUARTZ VEINS AND VEINLETS ARE BANDED CHALCEDONIC AND OPALINE QUARTZ VEINS CUTTING THE WALLROCKS. VEIN MATERIAL SAMPLED FROM THE GLORY HOLE CONSISTS OF HEAVILY FE- AND MN- STAINED MASSIVE COCKSCOMB TO SUGARY WHITE QUARTZ WITH OPEN DRUSY CENTERS AND ABUNDANT RIPPED-UP
Deposit FRAGMENTS OF BLEACHED, ARGILLIZED AND SILICIFIED ANDESITE-LATITE FRAGMENTS AND VEIN MATERIAL CONTAINING PYRITE PARTIALLY OXIDIZED TO HEMATITE OR PSEUDOMORPHED BY LIMONITE. WALLROCKS ARE FRACTURED OR SHEARD DUE TO FORCEFUL INTRUSION OF BEIN. ALSO, MAIN VEIN APPEARS TO HAVE BEEN SUBJECTED TO AN EPISODE OF SHEARING OR CROSS-FAULTING POSSIBLY DURING OR FOLLOWING EMPLACEMENT. BEST ORE OCCURS WHERE CROSS-STRUCTURES CAUSE THE VEIN TO SWELL.
