using backhoe configuration. The upper contact zones between the ore and overburden and the lower contact zone with the dunite base rock will be cleaned using cubic metre backhoes to minimize mining losses and ore dilution. The overburden and topsoil are to be removed by dozing and used for rehabilitation as soon as the bench has been mined.
