Copper Tertiary

Comments on the commodity information

  • GOLD/SULFIDE MINERALIZATION IS CONCENTRATED IN AND ADJACENT TO FRACTURES IN DISSEMINATED FORM AS WALLROCK IMPREGNATIONS AND/OR DISCONTINUOUS LENSES AND VEINLETS SMALL QUANTITIES PT AND AG RECOVERED BUT UNIMPORTANT IN SOUTH AFRICA TERMS. PT IS AN IMPURITY IN GOLD AND IS RECOVERED AT THE RAND REFINERY AS A CONSEQUENCE OF THE PURIFICATION PROCESS.
  • VERY LITTLE EXPLORATION CARRIED OUT HERE

Economic information

Geologic structures

Type of structure Regional
Structure description All Described Systems, Series And Included Sediments And Intrusives Are Regionally Severely Deformed, Closely Folded And Altered.
Type of structure Local
Structure description Folds, Faults And Fractures Have Produced Complex Structures, Making Stratigraphic Evaluations Difficult. Underlying And Surrounding Intrusive Granites Massive.

Ore body information

  • General form LINEAR AND POD/LENS
    Dip 40 - 90 DEG. E.
    Thickness 3M
    Depth to bottom 1350M

Controls for ore emplacement

  • Gentle Uplift Of Continental Mass, Followed By Diastrophism Regionally North Into Rhodesia. Swaziland System Is Thus Highly Folded, Fractured And Faulted Locally.

Comments on the geologic information

  • LOCAL AND REGIONAL INTRUSIVE GRANITE OCCURRENCES ARE NOT ADEQUATELY DEFINED BY NAME. ONE SOURCE REFERS TO GRANITE EXPOSURES AS KAAP VALLEY GRANITE PLUTON IN VICINITY OF MINE. CONFIRMATION NOT AVAILABLE.

Comments on the reserve resource information

  • NO RELIABLE ESTIMATES AVAILABLE (1970). POTENTIAL RESOURCES COULD EXCEED 100 MILLION METRIC TONS AND POSSIBLY BE AS MUCH AS 5,000 MILLION METRIC TONS.

Workings at the site

  • Type of workings Underground
    Overall depth 1350M

Comments on the workings information

  • MINING METHOD: SIDE HILL MINE ENTRY IS HORIZONTAL ADIT, WITH SECONDARY ADITS, AND INCLINED SHAFTS AND WINZES UNDERGROUND. NORMAL LEVELS ARE AT 55 METER INTERVALS. OVERHAND FULL SHRINKAGE STOPPING EMPLOYED. 3 - 6 METER PILLARS MAINTAINED BETWEEN ORE RECOVERY SHOOTS (CHINAMAN BOXES) ROCKPRESSURE IS NIL AND CRIB TIMBER SUPPORTS NOT NECESSARY. SHRINKAGE PILE IS SELF-SUPPORTING. WASTE ROCK EQUALS ORE RECOVERIES.

Comments on development

  • EXPAN$: 4.4 ( 1975 ) ; MILL.CAP: 0.1 MIL. MET. T/YR. ; ECON.COM: A SMALL PRODUCER BY SOUTH AFRICAN STANDARDS, BUT ECONOMICALLY STABLE AND A STEADY PRODUCER SINCE 1955. NEITHER OPERATING COSTS NOR ORE RESERVE ESTIMATES ARE AVAILABLE, BUT DEVELOPMENT AND COMPANY OUTLOOK SUGGEST LONG LIFE.
