The first wash plant (a temporary coal handling and preparation plant) was commissioned in the first half of that year. The plant is expected to process the coal at a rate of 100tph. It is equivalent to 600,000tpa of runofmine (ROM) coal. The first export shipment of the thermal coal from the mine was in December 2011.
