Comments on the reserve resource information

  • ORE RESERVES HAVE ONLY BEEN ESTABLISHED TO A DEPTH OF 4.5 METERS. THE ULTIMATE LENGTH AND WIDTH OF THE DEPOSIT HAS NOT BEEN REPORTED. THE RESOURCE IN Q-MATRIX 1 IS ONLY THAT ORE WHICH IS CONTAINED WITHIN AN "UNDEFINED BUFFER ZONE KNOWN AS ALPHA 1, ALPHA 2, AND DELTA AREAS". FROM THE THICKNESS AND A TONNAGE FACTOR OF 1.75 MT PER CUBIC METER. THE INDICATED AREAL EXTENT OF THIS RESOURCE IS ABOUT 360,000 SQ. METERS.
  • JOINT VENTURE BY PHILCHROME MINING AND ROCKLAND MINING INSTALLED A PILOT PLANT TO TREAT LOW-GRADE SOIL DEPOSITS. ONLY OFFICIAL PRODUCTION FROM THIS PLANT WAS 5,330 MT OF CONCS.IN 1984 (NO PRODUCTION IN 1985 & 1986. FOR ANALYSIS: 252,000 MTPY SOIL TREATED TO PRODUCE 21,430 MTPY CONCS. AT 42.2 % CR2O3. PRODS. AS CHROMITE MET IN AVAIL.STUDY.
