    Length 2133.6M
    Overall depth 266.4M
    Overall length 518.16M
    Overall width 60.96M

Comments on the workings information

  • MAIN WORKINGS INCLUDE THE MCMAHON SHAFT ON THE CUPRITE CLAIM AND AN OPEN PIT TO THE SOUTH OF THE SHAFT; ALSO THERE ARE SEVERAL INCLINED RAISES, WHICH CONNECT WITH THE MCMAHON UNDERGROUND AND TWO MAJOR LEACHING BASINS. FROM 1961 TO ITS CLOSING IN 1974, ZONIA WAS OPERATED AS AN OPEN PIT MINE, RETRIEVING COPPER ORE BY HEAP-LEACH TECHNIQUES

Comments on development

  • USBM WORK IN 1942 CONSISTED OF DIAMOND-DRILLING 11 HOLES AT 100-FOOT INTERVALS ALONG STRIKE OF ORE BODY, SEVEN TRENCHES AT 100-FOOT INTERVALS, 5 FEET DEEP TOTALING 1795 FT. MCALASTER FUEL OPERATED THE PROPERTY IN 1975. IN 1986, ANTIOCH RESOURCES AND PHELPS DODGE CORP. HELD DIFFERENT PARTS OF THE CLAIM GROUP. ANTIOCH WAS LOOKING AT CU-AG-AU MINERALIZATION AND PHELPS DODGE WAS LOOKING AT COPPER OXIDES. ANTIOCH REHABILITATED THE UNDERGROUND WORKINGS AND DID DETAILED MAPPING TO REVIEW THE PROPERTY'S PRECIOUS METAL RESOURCES. PHELPS DODGE WAS REVIEWING THEIR PROPERTY FOR OPERATION WITH A SOLVENT EXTRACTION ELECTROWINNING PLANT. TO PREPARE THE ORE BODY FOR IN SITU LEACHING, THE ORE BODY WAS SHOT USING 4,140,000 LB OF ANFO IN APRIL, 1973. THIS SHOTE IS ETIMATED TO HAVE BROKE MORE THAN 5,000,000 ST OF ORE.

Operator history (post-MRDS)

MRDS records operators as of each record's last update (≤ 2019). Some of the operators listed here have since changed hands or dissolved:

  • Phelps Dodge Corp. — acquired by Subsidiary of Freeport-McMoRan (2007)
    Acquired by Freeport-McMoRan Copper & Gold in 2007 in what was then the largest mining-industry deal ever (~US$26 B).
