Comments on the geologic information

  • THE MODIFIED PLACER THEORY, IN WHICH GOLD WAS DEPOSITED AS PLACER GRAINS THEN LATER MOBILIZED AND RECRYSTALLIZED DURING METAMORPHISM, IS THE MOST WIDELY ACCEPTED THEORY OF DEPOSIT FORMATION.
  • THE UPPER DIVISION OF THE WITWATERSRAND SUPERGROUP CONTAINS THE MOST PRODUCTIVE AURIFEROUS AND URANIFEROUS UNITS OF THE RAND; LESSER MINERALIZATION IS CONTAINED IN THE OVERLYING VENTERSDORP AND TRANSVAAL SUPERGROUPS.

Comments on other economic factors

  • ALL NEWLY MINED GOLD IN SOUTH AFRICA IS REFINED AT RAND REFINERY LTD., WHICH IS OWNED BY THE MINE MEMBERS OF THE CHAMBER OF MINES AND IS A NON-PROFIT ORGANIZATION. FEES CHARGED TO COVER THE COST OF OPERAION. THE DORE BULLION IS REFINED INTO 12.5 KILOGRAM GOLD BARS OR BLANKS FOR KRUGERRANDS, BOTH OF 996 FINENESS, AND 35 KILOGRAM ELECTROLYTIC SILVER BARS OF 999+ FINENESS. A SMALL AMOUNT OF ELECTROLYTIC GOLD OF 999+ FINENESS IS ALSO PRO- DUCED FOR INDUSTRIAL PURPOSES.
  • THE DORE BULLION IS SHIPPED IN RAND REFINERY ARMORED TRUCKS, THE COST OF WHICH IS INCLUDED IN THE REFINING FEES. COIN BLANKS ARE SHIPPED F.O.B. TO THE SOUTH AFRICAN MINT. GOLD BARS ARE SENT C.I.F. TO THE SOUTH AFRICAN RESERVE BANK DAILY. SILVER IS SOLD TO THE SOUTH AFRICAN MINT OR ON THE LONDON MARKET BY TENDER. THE COOKE MILL PRODUCES A HIGH PURITY AMMONIUM DIURANATE SLURRY WHICH IS SOLD TO NUFCOR F.O.B. MILL. ALMOST ALL OF THE SOUTH AFRICAN URANIUM IS PROCESSED AND MARKETED BY THE NUCLEAR FUELS CORPORATION OF SOUTH AFRICA (PTY) LIMITED, (NUFCOR). NUFCOR IS A PRIVATE SERVICE COMPANY AD- MINISTERED BY THE CHAMBER OF MINES OF SOUTH AFRICA AND IS OWNED BY THE MINES WHOSE URANIUM IS HANDLED BY NUFCOR.
  • THE MINE LEASE AREA CONTAINS 2,730 HECTARES. U1 ESTIMATED TOTAL OUTPUT IS 4,535,000 MTPY, DERIVED FROM THE FOLLOWING SOURCES: 1,100,000 MT FROM RANDFONTEIN TAILS, 400,000 MT FROM RANDFONTEIN UNDERGROUND, 3,000,000 MT FROM COOKE UNDERGROUND AND 35,000 MT FROM COOKE SLUDGE. U2 ESITMATED TOTAL OUTPUT IS 6,735,000 MTPY, DERIVED FROM THE FOLLOWING RESOURCES: 1,100,000 MT FROM RANDFONTEIN TAILS, 400,000 MT FROM RANDFONTEIN UNDERGROUND, 4,000,000 MT FROM COOKE UNDERGROUND, 35,000 MT FROM COOKE SLUDGE AND 1,200,000 MT FROM THE NEW SECTION UNDERGROUND. U3 ESTIMATED TOTAL OUTPUT IS 7,804,000 MTPY, DERIVED FROM THE FOLLOWING SOURCES: 1,500,000 MT FROM RANDFONTEIN TAILS, 4,000,000 MT FROM COOKE UNDERGROUND, 35,000 MT FROM COOKE SLUDGE AND 2,269,000 MT FROM THE NEW SECTION UNDERGROUND. U4 ESTIMATED TOTAL OUTPUT IS 7,269,000 MTPY, DERIVED FROM THE FOLLOWING SOURCES: 3,000,000 MT FROM RANDFONTEIN TAILS, 2,000,000 MT FROM COOKE UNDERGROUND AND 2,269,000 MT FROM THE NEW SECTION UNDERGROUND. U5 ESTIMATED TOTAL OUTPUT IS 6,269,000 MTPY, DERIVED FROM THE FOLLOWING SOURCES: 4,000,000 MT FROM RANDFONTEIN TAILS AND 2,269,000 MT FROM THE NEW SECTION UNDERGROUND. PRODUCTION IS CURRENTLY BEING PRODUCED FROM THE NO. 1 AND NO. 2 COOKE SHAFTS, WITH COMPLETION OF NO. 3 SHAFT SYSTEM SLATED FOR 1985. DEVELOPMENT OF THE NEW SECTION WILL REQUIRE 3 ADDITIONAL SHAFTS, TWO WILL BE FOR HOISTING (ONE AT KIMBERLEY AND ONE AT SOUTH), AND THE THIRD VEN- TILATION SHAFT WILL SERVE BOTH MAIN SHAFTS.
