Comments on the ownership information

  • TOTAL LAND HOLDING IS 9,065 HECTARES. LAND HOLDINGS OWNED AND PURCHASED BY FARMLAND HAVE INCREASED TRACT. SOME OR ALL OF FARMLAND/ONA AREA-SMALL OWNERSHIP PROPERTY (SEQ NO 0120490016) AND THE LIMESTONE LAND CO PROPERTY (SEQ NO 0120490009) ACREAGE, THEREBY RESERVES, HAVE BEEN COMBINED INTO THE FARMLAND HARDEE MINE PROPERTY.

Comments on the production information

  • PRECISE MILL RECOVERY INCLUDING SLURRY LOSSES= 94.1 %

Comments on the reserve resource information

  • MINE RECOVERY = 85% PEBBLE IS 7.6 % OF ORE. ADDITIONAL EXT. THERE ARE NO COMPANY PLANS TO DEVELOP THIS PROPERTY AT THIS TIME, THE RESERVES FROM LIMESTONE LAND SEQ NO. 012 049 0009 ARE INCLUDED WITH THIS PROPERTY SINCE ALL ARE OWNED BY FARMLAND INDUSTRIES.
