Sumitomo Metal Mining Co., Ltd.
Opening Ceremony at Quebrada Blanca Phase 2
Sumitomo Metal Mining Co., Ltd. (headquarters: Tokyo, Japan, “SMM”, Akira Nozaki President and Representative Director) and Sumitomo Corporation (headquarters: Tokyo, Japan, “SC”, Masayuki Hyodo President and Chief Executive Officer, Representative Director) are pleased to announce that the Quebrada Blanca Phase 2 project (“QB2 Project”), which is jointly owned by SMM, SC and major Canadian copper producer Teck Resources Limited (headquarters: Vancouver B.C., Canada, “Teck”), held an opening ceremony for the QB2 Project on October 26th at the QB port in Tarapacá, Chile.
Approximately 400 people attended the opening ceremony, including President Gabriel Boric of the Republic of Chile, government officials of the Republic of Chile and Japan, representatives from local communities in the Tarapacá region, members of financial institutions, and representatives of the project partners.
The QB2 Project will gradually increase ore throughput and copper concentrate production, and once it reaches full capacity, Quebrada Blanca will be one of the world's leading copper mines in terms of production.
In SMM's Long-Term Vision, the company aims to achieve attributable copper production volume of 300,000 tonnes per year. Continued progress towards full production at the QB2 Project is a major step towards achieving the target of its Vision.
SC will participate in the operation of the QB copper mine business and work together with its partners to contribute not only to the stable supply of copper, an essential resource for the widespread use of renewable energy and electric vehicles, but also to the development of the local economy by creating employment and business opportunities in the surrounding area and monitoring rare species living in the vicinity of the mine, while taking into consideration the impact on the surrounding areas and the environment.
