Vatukoula mine having previously been an open pit and underground operation is now only an underground mine (open pit mining was completed in 2012). Mining methods utilsed are longwall stoping and longwall panel mining. The process plant comprises a carbon-in-pulp (CIP) circuit. The operation is a high cost producer. It is dependent on financial backing of major shareholders to expand the mine to a capacity that will enable economies of scale to bring unit costs down.
