Comments on other economic factors

  • ORE IS PRE-CRUSHED AT MINE. THE DEPOSIT ACTUALLY FEEDS TWO PRIMARY MILLS: CLARABELLE MILL (CAPACITY IS 31, 750 TPD) AND FROOD-STOBIE MILL (CAPACITY IS 18,150 TPD). THESE MILLS, IN TURN, FEED A THIRD MILL: COPPER CLIFF MILL. CLARABELLE AND FROOD-STOBIE MILLS YIELD A BULK CONCENTRATE OF COPPER-NICKEL. THE COPPER CLIFF MILL SEPARATES THE BULK CONCENTRATE.
