Comments on the reserve resource information

  • M1C2 = M9C4. (75% PROBABILITY) RESOURCE TONNAGE IS FOR A 100 M. HIGH SECT THE ORE BODY.IT IS OPEN BEYOND THIS DEPTH,SO POSSIBILITY FOR ADDITIONAL ORE IS GOOD, ALTHOUGH IMPOSSIBLE TO QUANTIFY BASED ON AVAILABLE DATA (NO 50% PROBABILITY LEVEL ESTIMATED ) 65% OF THE TONNAGE IN Q-MAT. 1, COL. 2 IS LOW GRADE, DISEMINATED ORE (33% CR2O3 ); THE REMAINDER IS MASSIVE OR AVG. GRADE OF 38% CR2O3. BOTH KEFDAG WEST AND KEFDAG EAST OREBODIES ARE INCLUDED IN THE TONNAGE ESTIMATE.
  • OPERATING DIVISION IS SARKKROMLARI ISLETMESI GROUP. MILL CLOSED IN 1982 TO CHANGE MAGNETIC SEPARATION CIRCUIT AND RAISE CAPACITY. FOR ANALYSIS: 490,000 MTPY ROM FOR: 300,000 MTPY CONCS. AT 44 % CR2O3. ALL PRODUCTS TO ELAZIG SMELTER FOR PELLETIZING AND FEED TO THE 2 NEWEST FURNACES.
  • 1/89 INSITU DEMO.TONNAGE = FOR KEFDAG EAST AND KEFDAG WEST ORE ZONES TO THE 1500 LEVEL (200 M VERT.FROM HIGHEST OUTCROP).
