Comments on the geologic information

  • MINERALIZATION IN THE AREA CONSISTS OF SCHEELITE AND MINOR POWELLITE IN TACTITE AREAS NEAR LIMESTONE GRANODIORITE CONTACTS, AND COPPER IN SHEAR ZONES WHICH APPEAR TO CUT THE TACTITES. FOUR TACTITE ZONES, OF BOTH CONTACT AND STRATABOUND TYPES, HAVE BEEN OUTLINED AT COPPER KING. SCHEELITE IN THE VARIOUS TACTITE ZONES IS ERRATICALLY DISTRIBUTED, GENERALLY AS IRREGULAR LENSES AND PODS. ANOMALOUS AMOUNTS OF IRON (PYRITE), COPPER (CHALCOPYRITE, CHALCOCITE, MALACHITE) AND MOLYBDENUM (MOLYBDENITE) ARE FOUND WITHIN THE GRANODIORITE INTRUSIVE. IT SEEMS LIKELY THIS DISSEMINATED IRON-COPPER-MOLYBDENUM TYPE MINERALIZATION IS BOTH GENETICALLY AND SPACIALLY RELATED TO TACTITE DEVELOPMENT. THERE IS A POSSIBILITY FOR RECOVERY OF MINOR BYPRODUCT COPPER AND MOLYBDENUM SULFIDES FROM TACTITE BODIES MINED FOR TUNGSTEN.

Deposit THE COPPER KING CLAIMS WERE ORIGINALLY LOCATED FOR COPPER IN 1906 & 1908. THERE IS NO RECORD OF ANY COPPER PRODUCTION DURING THIS PERIOD. IN 1949 E.J. BOTTOMLEY ACQUIRED THE PROPERTY. IN 1952 THE PROPERTY WAS OPTIONED TO THE CORDERO MINING CORP. WHICH SHIPPED 750 TONS OF TUNGSTEN ORE RECOVERING 614 TUNGSTEN TON UNITS. AFTER THIS SEVERAL LESSEES WORKED THE PROPERTY ON A SMALL SCALE. WALLACE & DURBIN SHIPPED 193 TONS OF 0.22% WO3 IN 1956, PRODUCING 1,216 LBS OF TUNGSTEN. PROPERTY WAS IDLE 1956 TO 1968 WHEN THE PROPERTY WAS EXAMINED BY NEVADA COPPER & TUNGSTEN, INC. EXPLORATION STUDIES HAVE BEEN DONE UP TO THE PRESENT, BUT NO MINING ACTIVITY. PROPERTY IS DEVELOPED BY 3 SHAFTS 50-250 FT. DEEP, 2 PITS 6-8 FEET DEEP, 4 TRENCHES 40-50 FT. LONG, AND 3 SHALLOW TRENCHES. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
