Comments on the production information

  • PRODUCTION STARTED IN OCTOBER, 1975, IN LUMP ORE. NEW FRONTIER AND CECILIE ESTANISLAO, ANOTHER NEW PRODUCER HAD A COMBINED OUTPUT OF 1,987 DRY METRIC TONS OF METALLURGICAL CHROMITE CONCENTRATES IN 1975. 1976 - 2200 TONS OF LUMPY ORE WERE STOCKPILED WITH A GRADE OF ABOUT 50% CHROMITE. ALTHOUGH THE EXPLORATION SCHEME HAS JUST BEEN STARTED, INITIAL FINDINGS TO-DATE ALREADY INDICATE A MINE IN THE MAKING. PLATINUM AND PALLADIUM UNEXPECTEDLY APPEAR TO BE PRESENT IN THE AREA. THE COMPANY IS WAITING FOR MORE CLUES ON THESE PRECIOUS METALS A HIGH OCCURANCE OF NICKEL SULFIDE HAS BEEN DISCOVERED AT CONSIDERABLE DEPTHS. 1975 - NEW FRONTIER MINES HAS NEGOTIATED WITH HOCHMETAL FOR A JOINT VENTURE.

Comments on the reserve resource information

  • 1989 INSITU DEMO.TONNAGE IS FOR 4 DEPOSITS: LANDOC, LANSANG, KENTUCKY AND GOODLUCK.
  • THE RESERVES AT LAGONOY SHOULD BE SUFFICIENT TO LAST UNTIL THE YEAR 1990 SINCE THAT IS WHEN THE LEASE AGREEMENT RUNS OUT.

Comments on other economic factors

  • TRANSPORTATION COST MILL TO SMELTER: $41.65/MT.
  • THE "OTHER" TYPE OF STOPING IS "CAMOTE" MINING, WHICH IS AN UNSYSTEMATIC, LABOR INTENSIVE, SMALL SCALE METHOD ADOPTED FOR PHILLIPPINE CHROMITE OPERATIONS. ACCESS IS BY ADITS OR SMALL SHAFTS, BUT ALL OF THE WORKINGS DO NOT EXTEND TO GREAT DEPTHS.
