Comments on the reserve resource information

  • RESERVE GRADE & TONNAGE AS OF SEPT. 1978 ; BASED UPON AU PRICE OF $165/OZ. & STOPING WIDTH OF 126.1 CM. MAT.2 = GRADE & TONNAGE FOR TAILINGS DAM SLIMES. CAPACITY BASED UPON PLANNED MILL CAPACITY OF 340,000 MT/M (4,080,000 MTPY) BY JUNE 1977, A HISTORICAL 5% WASTE AND AN ASSUMED 350 DAYS/YR OPERATION. MILL IS CYANIDATION PLANT. YIELD, 1975, WAS 10.89 G/MT, YIELD, 1976, WAS 10.52 G/MT, YIELD, 1977, WAS 8.65 G/MT (GRADE REDUCTION DUE LARGELY TO FIRES IN NO. 4 SHAFT AREA, EXPECTED YIELD WAS 9.2 G/MT). RECOVERY % CALCULATED BY DIVIDING EXPECTED 1977 YIELD (9.2 G/MT) BY 1976 RESERVE GRADE (13.9 B/MT). ALSO PYRITE FLOTATION PLANT ONSITE WITH TREATMENT CAPACITY OF 570,000 MT/M (6,840,000 MTPY) OF TAILINGS DAM SLIMES.
