Minera Los Pelambres, one of the world’s leading copper producers and operated by Antofagasta plc and a Japanese consortium that includes Marubeni Corporation (hereinafter, “Marubeni”), has been awarded the Copper Mark*1 as of Nov 30, 2022.

The Copper Mark, founded by the International Copper Association (“ICA”)*2, is a comprehensive, credible assurance framework that demonstrates the copper industry’s responsible production practices and industry contribution to the United Nations SDGs (Sustainable Development Goals).

Minera Los Pelambres became the 10th in Chile and the 31st in the world to receive the Copper Mark. Following Marubeni’s previous announcements that Minera Centinela and Minera Antucoya, which are both 30% owned by Marubeni, were awarded the Copper Mark, Marubeni is pleased to announce that, with Minera Los Pelambres also having received the Copper Mark, all copper mines in which Marubeni participates have now received this distinguished designation.

Going forward, Marubeni will focus on the continuous improvement of responsible copper production in the copper industry and aim to strengthen the company’s commitment to the SDGs.

*1: Copper Mark
The Copper Mark was founded by the ICA, and the Copper Mark company was established as an independent entity in 2019. In order to be identified as a contributor to SDG 12 and receive the Copper Mark, copper producers are assessed against a set of 32 responsible production criteria.

*2: International Copper Association
The ICA (headquartered in Washington, D.C.) leads the world’s copper industry on issues critical to securing copper’s future growth and achieving the SDGs. ICA’s 36 members represent a majority of the world’s primary copper production, some of the largest mid-stream smelter/refiners, and 10 of the world’s largest copper fabricators.
