Ipillo is a regional Target. This area hosts polymetallic veins within an intrusive granodiorite. During 1991-1997, Centromin mined the Poggi 1 vein and produced 70,786 tonnes of ore at average grades of 97 g/t Ag, 2.28% Pb, 0.53% Cu and 5.89% Zn. Abundant veins and veinlets occur over an area of 2 km2 and stockworks of veins occur in large portions of the veined area. The potential for open-pitable stockwork deposits as well as vein-hosted deposits is considered to be high by the mine’s staff.
