Controls for ore emplacement

  • Bedding Planes, Fractures

Comments on the geologic information

  • ARSENOPYRITE REPLACES BOTH LIMESTONE AND ALASKITE IN PLACES. ARSENOPYRITE WAS DEPOSITED IN FRACTURES IN THE QUARTZ, WHICH FRACTURED BETTER UNDER STRESS THAN DID THE ENCLOSING LIMESTONE SCHIST. ORE DEPOSITION BY RISING SOLUTIONS IS INDICATED.

Workings at the site

  • Type of workings Surface/Underground
    Length 91.44M

Comments on the workings information

  • SEVERAL CUTS AND TUNNELS, THE LONGEST BEING 220 FEET. A 240-FT. LONG PROSPECT TUNNEL WAS RUN BELOW THESE IN 1903, UNDER THE DIRECTION OF TONOPAH PARTIES, BUT DID NOT REACH ANY ORE.

Comments on development

  • ORE WAS TREATED IN CHIATOVICH'S MILL AT SILVER PEAK AND THE TAILINGS WERE CHLORINATED. ATORTUOUS, 240-FT. TUNNEL WAS RUN IN 1903 BY TONOPAH INTERESTS, BUT DID NOT INTERSECT ORE.
