Ore controlINTERSECTIONS OF NE AND NW STRUCTURAL ELEMENTS POSSIBLY CONTROLLED THE LOCATION OF CALDERA STRUCTURES WHICH IN TURN WERE STRUCTURALLY FAVORABLE FOR THE DEVELOPMENT OF QUARTZ VEINS (A POPULAR THEORY BASED ON VERY LIMITED FIELD EVIDENCE). PROBABLY CONTROLLED BY REGIONAL LINEAMENTS BUT NOT CALDERA STRUCTURES. PROBABLY SAME SECONDARY ENRICHMENT IN GOLD IN HIGHER LEVELS.
