Pucarrajo was an underground polymetallic mine, that produced seperate lead and zinc concentrates. Before being placed on care and maintenance in 2009 it was operating at approximately 1,000t/d ore milled. Nyrstar had planned to reopen this operation by the end of 2012 or the beginning of 2013 after heavy exploration and development. Nyrstar have concluded that Pucarrajo has limited scale and marginal economics, therefore it has been deemed a non-core asset and discussions for divestment were said to be ongoing through H2 2014. No exploration and development work was carried out since the acquisition of the mine. The accompanying analysis assumes that this operation would continue under care and maintenance.
