Comments on the reserve resource information

  • IN ADDITION TO THE IDENTIFIED CU GRADES, THE ORE CONTAINS MEASURABLE AU, AND AG (0.06 G/MT AND 1.53 G/MT, RESPECTIVELY).
  • CERNA REPORTS THE COPPER ORE GRADE AT ASSAREL AS 0.3% AND THE MINE CAPACITY AS 10,000 MT. METALLGESELLSCHAFT REPORTED THAT ASSAREL WAS UNDER DEVELOPMENT AND WAS EXPECTED TO REACH FULL PRODUCTION OF 35,000 MT ORE/DAY IN THE NEXT 5 YEARS.
  • COPPER OXIDE ORE REPRESENTS A MIXED SULFIDE/OXIDE ORE. CRU REPORTS THAT 205M MT OF THE DEPOSIT IS SULFIDE ORE, @ 0.38% CU, AND 92M MT IS MIXED SULFIDE/OXIDE, @ 0.34% CU.
  • 205M MT OF RESOURCE IS SULFIDE ORE, @ 0.38% CU, AND 92M MT OF RESOURCE IS MIXED SULFIDE/OXIDE ORE, @ 0.34% CU (CRU, 1990). CRU ALSO REPORTED AN ADDITIONAL 160M MT ORE BODY, CU GRADES RANGING FROM 0.26% TO 0.32%, LOCATED NEAR CURRENT MINE LOCATION CRU REPORTS THAT THE DEPOSIT HAS THREE TYPES OF ORE: LESS THAN 5% CU OXIDE, MIXED SULFIDES WITH OXIDES (5 - 20%), AND MORE THAN 20% OXIDES.

General comments

Subject category Comment text
Deposit ALTHOUGH MO CONCENTRATE PRODUCTION IS REPORTED BY CRU, NO DATA IS AVAILABLE ON QUANTITY. THE MINE IS LOCATED IN A BULGARIAN NATURE RESERVE AND SIGNIFICANT PRESSURE IS BEING APPLIED BY VARIOUS ENVIRONMENTAL GROUPS TO SHUT-DOWN OPERTIONS AT THE MINE. PARTICULAR EMPHASIS HAS BEEN FOCUSED ON THE WASTE DUMPS AND LEACHING ARES.
