In Chile, we hold stakes in the Centinela, Antucoya, and Los Pelambres copper mines. Together with our partner, the U.K.-based Antofagasta plc, we are committed to ensuring a stable supply of copper, which is essential for achieving a decarbonized society. Across all our copper mines, we pursue sustainable operations with low environmental impact, including transitioning to renewable energy sources for power and conserving water resources through the use of seawater. We also aim to further increase the value of our assets through the Centinela expansion project and the further development of our existing mines.
Copper concentrates and cathodes
In Australia, we hold a stake in the Roy Hill iron ore mine, which is a highly cost competitive project, as the mine and its associated railway and port facilities are all owned by a single parent company. In addition to further improving the stability and efficiency of operations through remote management and automation of mining trucks, Roy Hill is also actively working to reduce greenhouse gas emissions by switching to renewable energy sources. We will contribute to society and the steel industry by ensuring a stable supply of iron ore, the raw material necessary to produce steel, which is expected to see continued demand growth as an essential metal for global economic growth and urbanization.

We are advancing our steelmaking coal business with interests in the highly cost competitive Jellinbah East, Lake Vermont, and Hail Creek coal mines in Australia. In June 2025, we increased our stake in Jellinbah Group, which holds interests in the Jellinbah East and Lake Vermont mines, to 40%. We will continue to explore expansion opportunities, including adjacent mining areas, to maintain and enhance cost competitiveness and reinforce our earnings base.

Through investment in the Alouette Aluminum Smelter in Canada, which has the largest production capacity in North America, and the Portland and Boyne Aluminum Smelters in Australia, we contribute to society and the aluminum industry by ensuring a stable supply of aluminum, a material essential to achieving a decarbonized society through electrification and weight reduction. The Alouette Aluminum Smelter is a world-class low-CO2 aluminum smelter that runs on hydropower, while efforts are also underway to improve the sustainability of power usage at the Portland and Boyne smelters.
Aluminum ingots
In addition to upstream mining development within the metal supply chain, we are advancing new trade and business development in midstream and downstream sectors for metal and mineral resource products where growth is anticipated. We are strengthening our supply chain and business foundations through investments such as our stake in Pan Pacific Copper, while also expanding our metal and mineral resource business initiatives in growth sectors like EVs and semiconductors as well as in regions with further growth potential such as the U.S. and India.
Semiconductor-related materials; EV-related metal materials; copper cathodes and other metal materials
Through our extensive global network, we accurately grasp market trends and conduct wide-ranging trade in products and regions with growth potential. Through the interface we have built up over the years with customers in the steelmaking, electric power, automobile, and metal product industries (including electric wires and aluminum rolling), we delve deeply into the needs and challenges of both society and consumers, leveraging our sales and marketing capabilities to provide a wide range of products (including green materials) and high-value-added services.
Steel materials, ferroalloys and cement-related materials; non-ferrous metal raw materials, ingots, and related products; battery materials
In our environmental and circular economy businesses, Marubeni handles materials which are essential for promoting electrification, such as battery materials and ferroalloys for electrical steel sheets used as raw materials for motors. In the recycling sector, we handle metal scrap and are investing in aluminum recycling operations in Vietnam, as well as battery waste collection and recycling businesses in North America and Europe. Furthermore, in the area of carbon management, we handle carbon-neutral products and participate in investments in Carbon Capture and Storage (CCS) projects in Canada.
Recycled materials from ferrous and non-ferrous metals; aluminum scrap; battery waste
Through investments in Marubeni-Itochu Steel and Marubeni Construction Material Lease, we are promoting steel products relevant to all industries and are a one-stop supplier to meet customer needs. In collaboration with other Marubeni business divisions and Group companies around the world, we are working to expand the earnings of the steel products business by leveraging our comprehensive strengths.
