Comments on the commodity information

  • ORE MINERALS LISTED ABOVE ARE REPORTED FROM MAMMOTH-REVENUE MINE, AND ALTHOUGH NOT ALL ARE SPECIFICALLY NOTED AT OTHER MINES IN DISTRICT, THEY ARE GENERALLY APPLICABLE TO THEM (BIRD, 1973). ARSENOPYRITE REPORTED BY PATTON (1917) CITED FOR ENTIRE DISTRICT. PETZITE (TELLURIDE) REPORTED BY PATTON IN GILMORE AND PLATORO DISTRICTS WAS PROBABLY MISIDENTIFIED SULFIDE (BIRD, 1973). MINOR PRODUCTION OF CU AND PB UNCERTAIN DUE TO LACK OF OLDER PRODUCTION RECORDS.

Deposit MINE LIES IN AXELL DISTRICT AND DEVELOPS N TO NW-TRENDING ARCUATE FAULT THAT INTERSECTS THE GENERALLY N 55 E-TRENDING CALIFORNIA GULCH (MAJOR DAWN) FAULT ABOUT 0.45 MILE SOUTH OF MINE (AS MAPPED BY BIRD, 1973). HOST FAULT APPEARS TO BE PART OF BIRD'S NW SYSTEM OF FAULTS AND FRACTURES REFLECTING NW TREND OF PLATORO FAULT ZONE WITHIN CORNWALL RESURGENT BLOCK. SOUTH PART OF FAULT AT INTERSECTION WITH CALIFORNIA GULCH FAULT HAS STRONG NORTHERLY COMPONENT CHARACTERISTIC OF THE RESURGENT RADIAL FAULTS. AS CALIFORNIA GULCH FAULT IS MAJOR SE-BOUNDING FAULT OF CORNWALL BLOCK, IT IS PROBABLY DEEP ENOUGH TO HAVE TAPPED UNDERLYING MAGMA CHAMBER, THUS PROVIDING CONDUIT FOR MINERALIZING SOLUTIONS. SOUTH PART OF GLACIER HOST FAULT MAY HAVE BEEN MINERALIZED THROUGH ITS INTERSECTION WITH CALIFORNIA GULCH FAULT.
