Deposit FRACTURE FILLINGS AND VEINS IN BRECCIATED ZONE. VEINS ARE 20 TO 180 CM WIDE. OXIDE/SULFIDE TRANSITION ZONE IS AT ABOUT 4700 M ALTITUDE. JUST S OF CERRO SANTA ISABEL IS A ZONE OF INTENSE ARGILLIC ALTERATION WITH 0.2 M WIDE VEINS STRIKING N80W DIPPING 70S ASSOCIATED WITH DISSEMINATED PYRITE, CHALCOPYRITE, AND CHALCOCITE. THIS COULD BE A PORPHYRY COPPER SYSTEM RELATED TO EPITHERMAL MINERALIZATION AT CERRO CANDELARIA. FRACTURES ARE FILLED BY PYRITE-SPHALERITE-GALENA IN SULFIDE ZONE, CASSITERITE AND AG MINERALS IN OXIDE ZONE. BRECCIA ZONES ARE CEMENTED BY CLAY AND LIMONITE. BRECCIA WAS REBRECCIATED PRIOR TO OXIDATION.
