Comments on other economic factors

  • A NEW VERTICAL SHAFT SYSTEM ID BEING PROPOSED FOR THE NORTH WEST PORTION OF THE PROPERTY (NEAR THE NO.6 SHAFT) TO MINE VAAL REEF MATER, ALL IN THAT AREA.
  • DUE TO LACK OF DATA FIELD SPACE, THE FEED GRADES OF THE COMMODITIES WERE ROUNDED. THERE ACTUAL FEED GRADES ARE: AU- 0.00098%, AG- 0.000098%, U- 0.01860.
  • THE INCREASE IN DEVELOPMENT COSTS FROM 1984 THROUGH 1994 IS DUE TO THE PLANNED DEVELOPMENT OF A SURFACE VERTICAL SHAFT SYSTEM. MINE AND MILL CAPITAL TOTALS WERE NOT GIVEN AS THIS REPRESENTS THE CAPITAL NECESSARY TO BRING THE MINE OR MILL INTO OPERATION AND THIS MINE AND MILL IS PRESENTLY OPERATING
