Comments on the production information

  • LARGEST GOLD PRODUCER IN KERN COUNTY. ORE EXTRACTED FROM ORE BODIES UNDERLYING PRE-MINERAL FAULTS VALUED FROM $25-$50/TON. MINT RETURNS INDICATED ABOUT 5 OUNCES OF SILVER FOR EACH $1000 IN GOLD. EARLY PRODUCTION FIGURES UNCERTAIN, SINCE ACCURATE RECORDS WERE NOT KEPT FOR MANY YEARS. YEARLY PRODUCTION PREVIOUS TO 1914 WAS $480,000. ABOUT 500 TONS OF ORE WAS CRUSHED DAILY, FREE MILLING, EXTRACTION ABOUT 98%.

Comments on the reserve resource information

  • ORE BODIES OCCURING ALONG MIDWAY TUNNEL BENEATH JUPITER FAULT. MILL RUNS ON ORE FROM THE NE-TRENDING ORE BODY SHOWED A RECOVERABLE VALUE OF $5.50/TON.

Workings at the site

  • Type of workings Surface/Underground
    Length 24139.5M

Comments on the workings information

  • MINE WORKINGS: THE MINE IS DEVELOPED BY APPROXIMATELY 15 MILES OF WORKING AND THREE SHAFTS. THE WORKINGS ARE DISTRIBUTED AMONG 14 LEVELS, OF WHICH THE RAND LEVEL, THE FIRST, SECOND AND THIRD LEVELS ARE THE MOST IMPORTANT. THREE SHAFTS HAVE BEEN SUNK FROM THE FLOOR OF THE GLORY HOLE. THE MAIN SHAFT IS SUNK ON AN INCLINE OF 45 TO A DEPTH OF 250 FT. THE SHAFT FOLLOWS DOWN THE FOOTWALL FAULT. THE HERCULES SHAFT IS SUNK ON AN INCLINE OF 40 TO A DEPTH OF 450 FT AND LOCATED BETWEEN THE JUPITER AND HANGING WALL FAULTS. THE RAND VERTICAL SHAFT IS LOCATED 150 FT SOUTHWEST OF THE HERCULES SHAFT AND HAS BEEN SUNK TO A DEPTH OF 450 FT. THE PRINCIPAL DEVELOPMENT WORK UNDER WAY AT THE TIME THE PROPERTY WAS VISITED WAS CONFINED TO RAISES ABOVE THE RAND LEVEL IN BLOCKS OF GROUND ABOVE THE FLOOR OF THE GLORY HOLE. SOME DEVELOPMENT WAS BEING DONE ON THE 100 FT AND 300 FT LEVELS ON THE PRINCE VEIN.

Comments on development

  • COLORADO RIVER INDIAN RESERVATION GREATLY RESTRICTED MINING SINCE THE 1870'S
  • MINE WAS OPERATED INTERMITTENTLY SINCE 1895 BY VARIOUS OPERATORS. ORE WAS TREATED AT VARIOUS MILL SITES.

Deposit PLACERS OCCUR ALONG GULCHES THAT DRAIN THE WESTERN SLOPES OF THE DOME ROCK MOUNTAINS: INCLUDES THE GOODMAN ARROYO AND ARROYO LA PAZ AND THEIR TRIBUTARIES. FERRAR GULCH CONTAINED THE RICHEST AND MOST PRODUCTIVE GRAVELS OF THE DISTRICT.
Deposit THE OREBODY IS A NETWORK OF QUARTZ VEINS AND STRINGERS IN QUARTZ MONZONITE AND SCHIST. THE GOLD OCCURS BOTH IN THESE VEINS OF QUARTZ AND STRINGERS AND IN THE QUARTZ-MONZONITE ADJACENT TO THE VEINS. THE PRESENT LOW-GRADE OREBODY CONSISTS OF A TGRIANGULAR BLOCK OF MINERALIZED QUARTZ MONZONITE, WHICH IS BOUNDED ON THE EAST BY THE HANGING WALL FAULT, ON THE NORTH BY THE JUPITER FAULT AND ON THE SOUTHWEST BY THE FOOTWALL FAULT. THIS OREBODY IS ABOUT 800 FT IN WIDTH, 1000 FT IN LENGTH AND WAS WORKED DOWN TO THE THIRD LEVEL. THERE ARE 6 PARALLEL VEINS THAT HAVE BEEN DEVELOPED INTHIS AREA WHICH STRIKE NORTHWEST AND SOUTHEAST. THE DIPS VARY FROM 30 NORTHEAST TO VERTICAL. THE JUPITER FAULT STRIKES N 75 E., DIPPING TO NORTH AT AN ANGLE OF 40; THE HANGING WALL FAULT STRIKES N 30 W, DIPPING 45 DEGREE NE; THE FOOTWALL FAULT STRIKES N 60 W, DIPPING 40 NE. THE HIGH-GRADE OREBODIES FORMERLY MINED OCCURRED ALONG VERICAL FISSURES AND FRACTURE ZONES AND ALSO BENEATH THE LOW-DIPPING PREMINERAL FAULTS
Deposit WHICH BOUND THE PRESENT LOW-GRADE OREBODY ON THE NORTH AND EAST. THE VERTICAL OREBODIES STRIKE NORTHWEST AND VARY IN WIDTH FROM SMALL VEINS TO OVER 75 FT. THE LARGEST OREBODIES OCCURRED IN THE NORTHWEST FISSURES AND FRACTURE ZONES AND HAD A LENGTH OF ABOUT 800 FT AND A THICKNESS OF 20 FT TO 75 FT. THE RAND VERTICAL VEIN WAS WORKED FOR A LENGTH OF 500 FT., AND HAD AN AVERAGE WIDTH OF 15 FT. IT WAS WORKED TO A DEPTH OF 400 FT. THE PRICE VEIN WAS WORKED FOR A LENGTH OF 500 FT. THE AVERAGE WIDTH WAS 10 FT AND IT WAS MINED TO A DEPTH OF 400 FT. THE OREBODIES THAT OCCUR AS MINERALIZED ZONES UNDERLYING THE PRE-MINERAL FAULTS POSSESS WELL-DEFINED HANGING WALLS FORMED BY THE GOUGE ALONG THE FAULT. THIS ORE IS COMPOSED OF MINERALIZED COUNTRY ROCK USUALLY QUARTZ MONZONITE AND SCHIST, WITH VERY LITTLE VEIN QUARTZ. OREBODIES OF THIS TYPE OCCURRED BENEATH JUPITER FAULT, ALONG THE LINE OF THE MIDWAY TUNNEL. THEY WERE FROM 200 FT TO 300 FT IN LENTH AND VARIED FROM 4 FT TO 16 FT IN THICKNESS. A
Deposit NEW OREBODY HAS BEEN DEVELOPED ON THE NORTH SIDE OF THE GLORY HOLE ALONG THE JUPITER FAULT ABOUT 100 FT IN ELEVATION ABOUT THE RAND LEVEL. A TUNNEL HAS BEEN DRIVEN SOUTHWEST 300 FT. AT 100 FT SOUTHWEST OF THE PORTAL, A SHOOT OF ORE WAS ENCOUNTERED WHICH HAS BEEN DEVELOPED FOR 200 FT IN LENGTH. THE VEIN VARIES IN WIDTH FROM 4 FT TO 13 FT. IT STRIKES NORTHEAST AND DIPS 30 TO 35 TO THE NORTH. THE FOOTWALL IS QUARTZ-MONZONITE. ON THE FOOTWALL THREE IS A CARBONIZED GOUGE 6 TO 12 INCHES THICK. THE MINERALIZED QUARTZ OCCURS ABOVE THE GOUGE. AVERAGE VALUE OF THE ORE EXTRACTED IS REPORTED TO $6 PER TON. SEVERAL RAISES HAVE BEEN PUT UP IN THIS SHOOT OF ORE FOR A DISTANCE OF 115.
Deposit 47 PATENTED CLAIMS AND 6 UNPATENTED CLAIMS. 796 ACRES.
