Comments on the production information

  • YEAR OF DISCOVERY NOT KNOWN. SOME MINING WAS DONE PRIOR TO WORLD WAR II.
  • PYONG-TAEK (P-T) ACTUALLY PRODUCES 4 DIFFERENT GRAPHITE CONCENTRATES, AND IT IS EXPECTED THAT YONG-UN (Y-U) ORE WOULD ALSO PRODUCE 4 CONCENTRATES, BUT THEY WOULD BE A LITTLE DIFFERENT FROM THE P-T PRODUCTS. FOR PURPOSES OF EVALUATION, 3 OF THE PRODUCTS, IN EACH CASE, HAVE BEEN COMBINED INTO A SINGLE PRODUCT. THUS, THE P-T MILL PRODUCES, IN THIS EVALUATION, A TOTAL OF 4 PRODUCTS, 2 FROM P-T ORE AND 2 FROM Y-U ORE. THESE PRODUCTS WILL BE REFERRED TO AS P-T GRAPHITE A AND B AND Y-U GRAPHITE A AND B. THEIR PHYSICAL CHARACTERISTICS FOLLOW: PRODUCT PERCENT MESH % OF P-T % OF Y-U CARBON SIZE PRODUCTION PRODUCTION ------------------------------------------------------------ P-T GRAPHITE A 85 -50 +100 10 0 P-T GRAPHITE B 76 -100 90 0 Y-U GRAPHITE A 80 -50 +100 0 11 Y-U GRAPHITE B 80 -100 0 89 ------------------------------------------------------------ AT FULL CAPACITY OPERATION FOR THE P-T MILL (1984-1990), P-T ORE WOULD YIELD ABOUT 150 MTPY OF P-T GRAPHITE A AND 1350 MTPY OF P-T GRAPHITE B. YONG-UN ORE WOULD YIELD ABOUT 160 MTPY OF Y-U GRAPHITE A AND 1270 MTPY OF Y-U GRAPHITE B. THE ONLY MILL CAPITAL EXPENDITURES AFTER 1982 ARE THE ADDITION OF A CONE CRUSHER AND ADDITIONAL WORKING CAPITAL, BOTH RELATED TO THE PROCESSING OF HANDSORTED ORE FORM YONG-UN. PRODUCTS A THROUGH F ARE FROM P-T ORE AND REPRESENT CHANGES IN PRODUCTION RATES. PRODUCTS G AND H ARE FROM Y-U "ORE." THE OP. COST SHOWN FOR PRODUCTS G AND H IS BASED ON 4700 MTPY OF HANDSORTED ORE FEED AND IS IN ADDITION TO THE OP. COST FOR MILLING P-T ORE.

Deposit COST DATA FOR THIS PROPERTY WERE GATHERED UNDER BUREAU OF MINES CONTRACT J0225019, "THE DEVELOPMENT OF ENGINEERING AND COST DATA FOR FOREIGN GRAPHITE PROPERTIES"; THE CONTRACT WAS AWARDED TO ZELLARS-WILLIAMS, INC. IN SEPTEMBER 1982. THE YONG-UN (Y-U) AND PYONG-TAEK (P-T) MINES WILL BOTH FEED THE P-T MILL. THE FOLLOWING DESCRIPTION SHOWS THE RELA- TIONSHIP BETWEEN THESE TWO PROPERTIES: IN 1982, THE P-T MILL WILL HANDLE ONLY 13,400 MT OF ORE FROM THE P-T MINE. THE Y-U MINE AND "MILL" WILL BE UNDERGOING PREPRODUCTION DEVELOPMENT IN 1982. IN 1983, Y-U WILL PRODUCE 14,800 MT OF ORE WHICH WILL BE HAND- SORTED TO PRODUCE 4700 MT OF PRODUCT (AT 30% CARBON) THAT WILL BE SHIPPED TO THE P-T MILL FOR FURTHER PROCESSING. IN 1983, P-T WILL INCREASE ITS MILL FEED TO 15,000 MTPY. IN 1984, THE P-T MINE WILL AGAIN INCREASE ITS MILL FEED TO 30,000 MTPY. IN 1990, THE Y-U DEPOSIT WILL MINE OUT, AND ALL FEED TO THE P-T MILL WILL AGAIN COME FROM THE P-T MINE AT A RATE OF 30,000 MTPY UNTIL FINAL MINEOUT IN 2016. THE DATABASE FOR Y-U WILL ONLY REFLECT COSTS DIRECTLY RELATED TO MINING OR HANDSORTING OF Y-U ORE. ALL COSTS RELATED TO MILLING OF Y-U ORE ARE SHOWN IN THE P-T DATABASE (BOTH CAPITAL AND OPERATING). HANDSORTING COSTS AT Y-U ARE INCLUDED IN THE Y-U MINE OP. COST. THE DEPOSIT CONSISTS OF 6 OREBODIES (ONE IS MINED OUT) HAVING VARIABLE DIMENSIONS. AVERAGE THICKNESS IS 4 M.
