Comments on the reserve resource information

  • 75% PROBABILITY LEVEL IS CALCULATED OVER A STRIKE LENGTH OF 11,800M BUT ONLY 4,500M HAS THE 1000M DOWN DIP EXTENSION. Q-MATRIX ONE IS THE IN-SITU RESOURCE. COL 1 IS THE TONNAGE FOR THE WATERKLOOF FARM, COL 2 IS THE ZWARTKOPPIES FARM TONNAGE, AND COL 3 IS THE COMBINED TONNAGE. Q-MATRIX 2 REPRESENTS THE RECOVERABLE RESOURCE TONNAGE. ONCE AGAIN, COL 1 IS THE TONNAGE FROM THE WATERKLOOF FARM, COL 2 IS THE ZWARTKOPPIES FARM TONNAGE, AND COL 3 IS THE COMBINED TONNAGE FOR BOTH FARMS.
  • 1/89 INSITU DEMO.TONNAGE FOR STEELPORT SEAM ON BOTH FARMS; 4,500 M STRIKE TAKEN TO 320 M VERT., 7,300 M TO 160 M VERT. 90% REC.
  • COMPRISED OF BOTH THE WATERKOP 378 FARM AND THE ZWARTKOPPIES 376 FARM. 250,000 MTPY OPERATION DEVELOPED ON WATERKOP FARM IN 1977/1978 BUT SHUT DOWN SHORTLY THEREAFTER. 500,000 MTPY ROM (270,000 FROM WATERKOP AND 230,000 FROM ZWART- KOPPIES) FOR: 102,000 MTPY LUMP AT 44.0% CR2O3 AND 344,000 MTPY FINES AT 44.5% CR2O3.
