Contonga zinc mine
Contonga is an underground Zn-Pb-Ag-Cu mine, located approximately 470km from Lima, Peru. Following the acquisition of the operation by Nyrstar in 2010, the mill capacity was expanded from 0.66kt/d to 0.99kt/d by 2013 which was achieved ahead of schedule in Q1 2012. In 2015, the Contonga operation was reportedly authorised to process 1,200t/d. In December 2016, subsidiaries of Glencore entered into a share purchase agreement to purchase the Contonga mine from Nystar for US$21 million. Following three years of production, Glencore put the mine under care and maintenance in H1 2019.
