Geology and mineralization
More than 15 major silver and base metal-rich epithermal vein sets have been identified within the Caylloma district. The veins are hosted by Tertiary calc-alkaline andesitic volcanic sequences that unconformably overlie folded marine sediments. The veins are one to 25 meters wide, up to four kilometres long, typically trending north-easterly and dipping moderately to steeply to the southeast or northwest.
