Comments on the production information

  • PB (RESIDUE CONCENTRATE) CONSISTS OF LEUCOXENE, ALTERED ILMENITE, AND RUTILE. PD (ZIRCON CONCENTRATE) IS PORTION OF TOTAL CONCENTRATE PRODUCED AT THE TRAIL RIDGE OPERATION (012-019-0001) DRY MILL (152 MT) THAT IS ATTRIBUTED TO THE HIGHLAND OPERATION. (HI-ZIRCON DRY MILL TAILINGS FROM HIGHLAND ARE PROCESSED IN A ZIRCON CIRCUIT AT THE TRAIL RIDGE OPERATION.)
  • PRODUCTION STATISTICS ARE FROM BUMINES PRODUCTION STATISTICS AND HAVE BEEN CONVERTED FROM SHORT TONS TO METRIC TONS. 1981-1986 PRODUCTION FROM BU MINES PRODUCTION STATISTICS

Comments on the reserve resource information

  • DU PONT HAS NOW ACQUIRED ADJACENT PROPERTY PREVIOUSLY NOT INCLUDED IN OUR EVALUATION. THEY ACQUIRED IT FROM NL INDUSTRIES. ADIT UPDATE, JAN. 1993: BASED ON INFORMATION FROM THE PLANT MANAGER, RESERVES WERE ESTIMATED BASED ON CAPACITY AND MINE LIFE. THE GRADE (TIO2) IS AN AVERAGE FOR ALL THE DUPONT MINES IN THE AREA. THE RESERVES ARE SHOWN ALSO IN Q-MATRIX 3, COL 1. THIS PROPERTY IS CURRENTLY CLOSED TO ACCOMADATE MINE PLANNING OF THE MAXVILLE TRACT, BUT WILL RESUME OPERATIONS EVENTUALLY.
  • ASSAY LINE 01 EQUALS COMMODITY 01, ILMENITE CONCENTRATE. ASSAY LINE 02 EQUALS COMMODITY 02, RESIDUE CONCENTRATE. ASSAY LINE 03 EQUALS COMMODITY 03, STAUROLITE CONCENTRATE. ASSAY LINE 04 EQUALS COMMODITY 04, ZIRCON CONCENTRATE. M2C1=M1C1-35,000,000 MATRIX 2, COL 1 = MATRIX 1, COL 1 - 35,000,000 THE JAN 1987 RESERVE ESTIMATE EQUALS THE JAN 1981 RESERVE ESTIMATE MINUS THE TOTAL 1981-1986 PRODUCTION. MINE REC = 95%, MILL REC = 84%, MILL FEED GRADE = IN SITU ORE GRADE RESERVES IN Q-MATRIX 3, COL 1 ARE FOR THE ADIT DATA SET. THE RESERVES WERE ESTIMATED BASED ON MINE LIFE AND CAPACITY.
