The Promontorio Sur vein zone can be traced on surface for 1.5 km as quartz-carbonate veinlets hosted in andesitic agglomerate. The veinlets are interpreted as representing high levels of the epithermal system, with potential for high-grade mineralization at depth. Outcrop geochemical sampling shows anomalous values of silver, gold, and base metals along the structure. Minaurum drilling shows that the andesite overlies altered and mineralized limestone, with mineralization occurring at a fault contact betwe ...
