　Marubeni Corporation plans to proceed with a large-scale expansion of its Roy Hill iron ore joint venture in Australia. Marubeni and the joint venture partner are working out a plan to expand the shipment volume from the current level of 65 million tons per year to 100 million tons around 2025 after about two years of expansion work. While expanding the infrastructure of railroads and ports, the company plans to procure ore from neighboring mining areas and expand the scale of sales.
