Comments on other economic factors

  • THERE ARE ACTUALLY TWO MILLS: A PRIMARY AND SECONDARY MILL. THE PRIMARY MILL IS THE CLARABELLE MILL. CU-NI CONC IS THEN SENT TO THE COPPER CLIFF MILL VIA TWO 1600 METER PIPELINES FOR FLOTATION AND SEPARATION. MILL IS ACTUALLY PUTTING OUT TWO CONCENTRATES, NICKEL AND COPPER, FROM ONE NICKEL/COPPER BULK CONCENTRATE.
  • THE MAJOR MINING METHOD AT THE CREAN HILL MINE IS BLASTHOLE STOPING WITH VERTICAL CRATER RETREAT AND SHRINKAGE MINING METHOD.
