Comments on the reserve resource information

  • GOLDER ASSOCIATES RESERVE/RESOURCE ESTIMATE (?) IS BASED ON THE MINE PRODUCTION RATE OF 430000 MTPY, FOR 15 YEARS BEGINNING IN 1981 AND ENDING IN 1995. GOLDER ASSUMES A 55% MINE RECOVERY FACTOR TO COME UP WITH AN INSITU ORE TONNAGE OF 11.7 MILLION MT, IN 1981. THE GRADE ESTIMATE FOR THE RECOVERABLE BAUXITE ORE IS 53.0 % AL2O3; THEIR IS NO SUPPORTING BACK UP FOR THESE ESTIMATES. 1987 STUDY RESERVE/RESOURCE ESTIMATE BASED ON PUBLISHED ESTIMATE OF 3.0 MILLION MT RECOVERABLE ORE. USING THE 55% MINE RECOVERY, INSITU ORE COMES TO 5455000 MT. THE GRADE IS ASSUMED TO BE 50% AL2O3. QM1 COL3 = QM9 COL6.
  • THE AL2O3 GRADE FOR THE 1987 PUBLISHED RECOVERABLE RESERVES IS UNKNWON
  • THE REFERENCE FOR THE PUBLISHED RESOURCES OF THIS MINE HAS NO cITATION ON THE PAGE. SEE MAFO ETD.
