Report summaryTayahua is a typical hydrothermal deposit consisting of “two orebodies”: a big manto copper skarn (Santiago primary copper orebody 3km long, 40m width, 600m deep and still open at depth) and around it the lead-zinc replacement mineralisation hosted in veins and chimneys.
In 2015 Tayahua operated a mill of 4kt/d for the copper ore and a mill of 1.5kt/d for the Pb-Zn ore. By mid 2017 it is expected to operate a 10kt/d copper concentrator, with the 4kt/d plant being placed on stand-by.
