Comments on the geologic information

  • WITWATERSRAND SYSTEM = CARBON LEADER + MAIN REEF (ABOUT 60 M ABOVE CL) VENTERSDORP SYSTEM = VENTERSDORP CONTACT REEF + ELSBURG REEF + KIMBERLY REEF VCR, ELSBURG, + KIMBERLY REEFS BASICALLY SUB-OUTCROP TOGETHER, WITH ONLY ABOUT 20-30 M SEPARATION, WHERE THEY OCCUR TOGETHER. TRANSVAAL SYSTEM = BLACK REEF SERIES (BLACK REEF) BLACK REEF WAS ONLY MINED ON LEVELS 3 & 4 IN THE PAST. IT DOES NOT PRESENTLY CONSTITUTE A MAJOR RESOURCE TARGET.
