Comments on the geologic information

  • SULFIDES FORMED AT THE CONCLUDING PHASE OF ALTERATION. AS- SOCIATED SULFIDES ARE CHALCOPYRITE, BORNITE, PYRRHOTITE, MOLYB- DENITE, AND COBALTITE. THEY ARE CLEARLY ASSOCIATED WITH EPI- DOTE, ACTINOLITE, QUARTZ, AND CALCITE. COMMERCIAL MINERALIZATION IS LOCATED IN SKARNS AND POST- SKARN METASOMATIC FORMATIONS. THE INTENSITY OF MINERALIZATION DEPENDS DIRECTLY UPON THE IRON INDEX OF THE ROCK-FORMING MINERALS. OXIDE ORE EXTENDS TO 12M AND OCCASIONALLY 30M.
  • ORE OCCURS IN THE SAYAK TROUGH, A COMPLEXLY FOLDED ASSEMBLAGE OF LOWER PALEOZOIC SEDIMENTS. ORE IS OF THE SKARN TYPE. ORE IS CONFINED TO A SECOND ORDER ANTICLINE, AND OCCURS IN A CONTACT ZONE WITH THE GRANODIORITES. IT HAS BEEN INTENSELY ALTERED. THE SKARN FIELD EXTENDS ALONG THE CONTACT WITH THE INTRUSION FOR 3KM, WITH A WIDTH OF 500-1,000M, AND A THICKNESS RANGING FROM 50-200M. TWO MORPHOLOGICAL TYPES OF ORE BODIES ARE RECOGNIZED: 1) SEGREGATIONS OF A COMPLEX, LENS-SHAPED ORE, LOCATED IN SKARNS AND RESTING CONFORMABLY WITH COUNTRY ROCKS; 2) STEEPLY-DIPPING LINEAR ZONES OF A VEINLET-SEGREGATED MINERALIZATION IN THE GRANITOIDS.

Comments on the reserve resource information

  • RESERVES SUFFICIENT FOR 10 YR OF PRODUCTION. CUTOFF GRADE IS 0.5% CU.

Comments on other economic factors

  • CURRENT MINE CONSISTS OF 2 OPEN PITS, THE SAJAK 1 AND TASTAU. SAJAK MINES ORE 0.75% CU AND 0.06% MO. 800KG AU AND 29T AG ARE RECOVERED ANNUALLY. TASTAU PIT IS 17KM FROM SAJAK PIT. IT MINES ORE 0.5% CU. ORE HAULED 2KM TO TIPPING POINT, WHERE IT IS LOADED INTO RAILCARS TO BALKHASH CONCENTRATOR. BENCH HEIGHT IS 7.5M.

Subject category Comment text
Deposit SAYAK DEPOSIT IS LOCATED IN THE NORTHEASTERN BALKHASH REGION IN KAZAKHSTAN. ORE FROM THE SAYAK MINE FEEDS THE BALKHASH CONCENTRATOR (SEQ. NO. 4590000142. THE DEPOSIT WAS DISCOVERED IN 1930 AND IS THE OLDEST DEPO- SIT FEEDING THIS SMELTER. MINING BEGAN IN 1970 RESOURCES FOR THIS DEPOSIT ARE NOT CURRENTLY AVAILABLE, BUT IT MAY BE THAT THEY ARE NEARING DEPLETION SINCE ADDITIONAL DEPOSITS ARE BEING DEVELOPED TO FEED THE SMELTER.
