Comments on the production information

  • COBALT PRODUCT IS EXPRESSED AS PURE COBALT BASED ON INPUT GRADE AND COBALT RECOVERY. COBALT HAD RECENTLY BEEN SHIPPED TO FINLAND IN THE FORM OF MIXED SULFIDES, BUT IT IS NOW LIKELY THAT YABULU IS UPGRADING IN ORDER TO REFINE COBALT.

Comments on the reserve resource information

  • ALTHOUGH SOME LOW GRADE RESOURCES EXIST SOME DISTANCE FROM THE MINE, THE CURRENT RESOURCE ONLY HAS ABOUT 2 YEARS OF PRODUCTION LEFT (2/88) AS A RESULT, MINE WILL IMPORT LATERITE ORE. LOWER FEED BUT HIGHER GRADES = ABOUT SAME PRODUCTION OF NICKEL AND COBALT. AT THAT TIME THE OPERATION WILL BE CONSIDERED A PROCESSING FACILTIY.
  • M1C1=M9C4. SINCE THE QUEENSLAND MINES RESERVES ARE EXPECTED TO DRY OUT SOON, QUEENSLAND NICKEL IS IMPORTING ORE FROM NEW CALEDONIA AND INDONESIA. THIS MAY INCREASE CONTAINED NICKEL PRODUCTION CAPACITY BY 4000-9000 TONNES AT THE REFINERY LEVEL, DEPENDING ON THE GRADES AND RECOVERIES.
  • ONLY ONE-TWO YEARS OF MINES RESOURCE EXIST. FACILTY WILL RELY ON NI-CO ORES FROM NEW CALEDONIA, INDONESIA AND PHILIPPINES

Deposit AT THE MINE SITE THE ORE IS CRUSHED AND SCREENED. IT IS THEN STOCKPILED AND BLENDED. TRAINS HAUL THE ORE TO THE REFINERY AT YABULU. AN AMMONIA LEACH PROCESS IS USED TO RECOVER THE NICKEL AND COBALT. NICKEL CARBONATE IS PRO- DUCED FROM THE NICKEL ORE AND IS TREATED FURTHER TO PRODUCE SINTERED NICKEL OXIDE. A NICKEL-COLBALT SULFIDE IS RECOVERED FROM THE COBALT.
