Deposit THE TOTAL ORE ZONE CONSISTS OF ABOUT A 20M THICK UPPER, PCT MN, AND A LOWER 6M THICK, 30 PCT MN MEMBER. THE MIDDLE MEMBER IS MINED AFTER REMOVAL AND STOCKPILING OF THE OF THE UPPER MEMBER; THE LOWER MEMBER IS LEFT IN PLACE. OVERBURDEN (ABOUT 45M) CONSISTS OF HARD LIMESTONE, IRONSTONE, AND SAND; THE SAND (ABOUT 7M) IS REMOVED BY A BUCKET WHEEL EXCAVATOR. HARD OVERBURDEN IS MINED IN THREE BENCHES; ABOUT 70 PCT OF IT IS USED AS BACKFILL IN MINED OUT AREAS. AN IN-PIT CRUSHER AND 2.2KM CONVEYOR SYSTEM WERE INSTALLED IN 1981. PRODUCTION IS ESTIMATED TO BE ON THE ORDER OF 1.2 MILLION T/YR. IN 1988 A 550,000 T/YR SINTER PLANT WAS CONSTRUCTED TO SINTER THE FINES (MINUS 6MM) GENERATED BY CRUSHING AND HANDLING ABOUT 30 PCT OF THE ORE. THIS PROCESS ALONE UPGRADES THE ORE FROM ABOUT 38 PCT MN TO 44 PCT MN; HOWEVER, SINCE LATE 1989, THE SINTER FEED IS UPGRADED BY HEAVY MEDIA TO ABOUT 44 PCT MN.
