| Deposit | MINERALIZATION CONCENTRATED IN VESICLES AT TOPS OF FLOWS AND FINE FRACTURES. ORE BODIES PARALLEL TO CONTACT OF ANDESITE WITH OVERLYING LIMESTONE. ORE AVERAGES 2 M THICK. THE CONTACT OF ANDESITE WITH OVERLYING LIMESTONE IS UNDULATORY SURFACE WITH CRESTS AND DEPRESSIONS. DEPRESSIONS ARE FILLED WITH CALCAREOUS SANDSTONE THAT FILLS CHANNELS (ANCIENT STREAM) BETWEEN LAVA FLOWS. ORE IS THICKEST IN CRESTS OF FLOWS. ARE ABOUT 4 CHANNELS ORE N80E, 21E PLUNGE, N70E, N60W. CHANNEL FILL INCLUDES ROUNDED PEBBLES OF MINERALIZED ROCK. ORE BODIES ZONED: BASAL ZONE OF BORNITE, MIXED ZONE OF BORNITE AND CHALCOPYRITE, UPPER ZONE OF CHALCOPYRITE AND PYRITE. FIRST TWO IN ANDESITE, THE UPPER ONE IN LIMESTONE. |
