Diversified miner Anglo American’s Quellaveco copper mine, in Peru, and its three managed copper operations in Chile – the Los Bronces and El Soldado mines and the Chagres smelter – have been awarded The Copper Mark following independent assessments against The Copper Mark criteria for responsible copper production.

These achievements mark the first award of The Copper Mark and The Molybdenum Mark for Quellaveco, while The Copper Mark awards were reaffirmed for the Los Bronces, El Soldado and Chagres operations, in addition to the Molybdenum Mark for Los Bronces, following their initial award in 2022.

Both Quellaveco and Los Bronces produce molybdenum as a by-product of their primary copper operations.

In addition, Anglo American reports, all four sites have achieved their first Copper Mark Chain of Custody award, demonstrating their commitment to responsible sourcing and supply chain traceability.

"Our efforts to assess our value chain against independent third-party standards are an important point of both differentiation and confidence in the responsible production of our product for customers, end-users and other stakeholders.

“Quellaveco is a blueprint for responsible mining and I am delighted that we have received this important accolade in recognition of everything that we do to ensure we live up to our stakeholders' expectations in the responsible production of copper, a key metal for the energy transition and maturing economies globally,” says Anglo American Peru CEO Tony Power.

"The reaffirmation of The Copper Mark achievement for our Los Bronces, El Soldado and Chagres operations reflects the sustained work of our teams to operate in accordance with the highest international standards, integrating sustainability into our decision-making.

“The Copper Mark not only recognises our performance but also strengthens trust with communities, regulators and investors, and supports our wider role in the responsible production of copper,” says Anglo American Chile interim CEO Tzveta Tchorbadjieva.

"Congratulations to Quellaveco on successfully completing its first assurance cycle and earning these awards.

“It's important to highlight that Quellaveco represents Anglo American's fourth awarded site, alongside the Los Bronces, El Soldado and Chagres operations in Chile. We look forward to deepening our relationship with companies like Anglo American that want to achieve assured responsible production,” adds The Copper Mark executive director Michèle Brülhart.

The on-site process of assessing Quellaveco and reassessing Los Bronces, El Soldado and Chagres through the Copper Mark's Assurance Process began in October 2025.

Anglo American explains that the sites were assessed against 33 performance areas, including environmental risk management, energy consumption, waste and tailings management, mine closure and reclamation, occupational health and safety, business integrity, community and stakeholder engagement, human rights and cultural heritage.

The Copper Mark is the leading assurance framework to promote responsible practices across the copper, molybdenum, nickel and zinc value chains.

The organisation works with companies and organisations throughout these metals' value chains to enable them to better understand and meet the increasing demands for independently verified responsible practices and to contribute positively to sustainable development.
