Austria Duvaz is a small polymetallic underground mine located adjacent to the Toromocho open-pit project and producing copper, lead and zinc concentrates. The concentrator operates at a capacity of 750t/d ore. In 2010 Austria Duvaz reached an agreement with Chinalco to operate until 2016. After this Austria Duvaz must move its milling operations. However, this deadline was continually extended. The estimated life of this operation is constrained by this agreement. By 2017 we have estimated a mine life until 2022. Concentrates are shipped through the port of El Callao in Lima.
