Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Location): UTM LOCATION MEASURED TO POSITION OF MCMAHON SHAFT AS DETERMINED FROM MAP OF THE WORKINGS; OPEN PIT PORTION OF MINE TO SOUTH OF SHAFT.

Comment (Production): POSSIBLY A FEW HUNDRED TONS OF HAND-SORTED ORE PRODUCED. NO PRODUCTION FIGURES (1947).

Comment (Deposit): DEPOSIT IS LOW GRADE, OXIDE AND SULFIDE FACIES MASSIVE SULFIDE DEPOSIT IN PROTEROZOIC METAVOLCANIC ROCKS. COPPER MINERALS DISSEMINATED IN SCHIST AND MONZONITE PORPHYRY INTRUSION REPORTED IN FILES. MINERALIZATION IN MONZONITE INTRUSION QUESTIONABLE AS SAME AGE AS ZONIA. MASSIVE.

Comment (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.

Comment (Workings): 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

Comment (Geology): IGNEOUS ROCKS OCCUR 0.4-0.6 MILES NORTH OF THE ZONIA MINE. THE IGNEOUS ROCKS ARE YOUNGER THAN THE METAVOLCANIC ROCKS AND ARE APPARENTLY UNRELATED TO THE MASSIVE SULFIDE DEPOSITS

Comment (Deposit): ZONIA AND MAMAHAN GROUPS OF CLAIMS. ZONIA CONSISTS OF 255.5 ACRES IN 14 PATENTED CLAIMS. MCMAHAN GROUP CONSISTED OF 175 ACRES OF UNPATENTED CLAIMS. MOST ASSESSMENT WORK DONE WITHIN THE UNION, BLACK PRINCE, SHAMROCK, UMPIRE, AND CUPRITE CLAIMS. MOST OF THE ORE BODY IS INDICATED WITHIN THE CUPRITE CLAIM. RECORD # M004613 BY K.H. JOHNSON AND S.C. CREASEY HAS BEEN INCORPORATED INTO THIS THIS RECORD AND DELETED FROM THE MRDS MASTER FILE. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
