Our company is subsidiary of one of Indonesia's largest and oldest business group. Currently, we are a leading supplier of antimony, manganese, iron ores and steel mills by-products. We have our own mining concessions throughout the Indonesian archipelago. We are currently working on several mining projects with Beijing based Chinese state owned mining company known as China National Geological & Mining Corporation. Our Chinese partner, who doubled as our technical consultant, had helped propelled our company to new heights in terms of production capacity and know how. We look forward to finding new market and partners through similar co-operations with fellow alibaba members.
We have now expanded our commodities range to include Nickel, Bauxite and high grade steel by-products. Mill Scales, for example, is our top seller. Its high Fe content up to 74% is used to blend with lower grade Iron Ores or Iron Concentrates to boost their Fe content to above 60% before selling to China Steel Mill with blast furnace.
We now have more than 500,000 MT of coal of various calories at our sales disposal with our latest expansion into coal mining, trading and investment. We have funded several coal mines with offtake agreements.
