Pachapaqui is an underground mine located at 4260-4320 m.a.s.l. in Ancash, Peru. Its material was processed by a 0.7-1.0 kt/d ore poly-metallic concentrator, producing copper, lead, zinc and bulk concentrates which were shipped through the port of El Callao. A mill expansion will increase the processing rate to 2.5kt/d. It is estimated to have a life of mine of 15 years after the operation restart.
