Completion Conditions Met for Project Financing of the Quebrada Blanca Phase 2 Project in Chile
Sumitomo Metal Mining Co., Ltd. (Headquarters: Tokyo, Japan hereinafter “Sumitomo Metal Mining“) and Sumitomo Corporation (Headquarters: Tokyo, Japan) are pleased to announce that all completion conditions—including production benchmarks and cost requirements—stipulated in the project financing agreements for the Quebrada Blanca Phase 2 Project (hereinafter “QB2 Project”) in Chile have been successfully met. The QB2 Project is being jointly developed with major Canadian copper producer Teck Resources Limited (Headquarters: Vancouver B.C., Canada, hereinafter “Teck Resources”).
The project financing agreements, for a facility totaling USD 2.5 billion, were signed with a syndicate of lenders, including government-affiliated financial institutions such as the Japan Bank for International Cooperation (JBIC), as well as private financial institutions, including Sumitomo Mitsui Banking Corporation, Mizuho Bank, Ltd., and MUFG Bank, Ltd. Sumitomo Metal Mining and Sumitomo Corporation, alongside Teck Resources, had provided guarantees to the lenders in accordance with their respective ownership interests. With the achievement of completion, these guarantees have now been terminated.
The Quebrada Blanca Copper Mine has an estimated mine life of 27 years (as of FY 2023). It has an anticipated annual copper production volume of approximately 230,000 to 310,000 tonnes for 2025-2028 (estimated as of today’s date). The mine integrates cutting-edge technology, including a remote monitoring and operation system for heavy machinery from an integrated operations center located 1,500 km away in Santiago.
In Sumitomo Metal Mining's Long-Term Vision, Sumitomo Metal Mining aims to achieve attributable copper production volume of 300,000 tonnes per year. Achievement of completion at the QB2 Project is a major step towards achieving the target of its Vision.
Sumitomo Corporation, as an operating partner of the QB2 Project, is committed to ensuring a stable supply of copper—an essential resource for the advancement of renewable energy and electric vehicles—while contributing to the development of the local economy through job creation and business opportunities in the surrounding region, in collaboration with its partners.
