VANCOUVER, British Columbia –
Capstone Copper Corp. (“Capstone” or the “Company”) (TSX: CS) has committed to the Copper Mark at its Mantos Blancos and Mantoverde operations in Chile. The Copper Mark is an assurance framework to promote responsible production practices and demonstrate the industry’s commitment to the United Nations Sustainable Development Goals. Within one year, Mantos Blancos and Mantoverde will be assessed and independently verified against the Copper Mark’s 32 responsible production criteria, including environmental management, greenhouse gas emissions, human rights, community health, safety and development, and governance.

John MacKenzie, CEO of Capstone commented, “I am proud to share that our Mantos Blancos and Mantoverde operations have joined the Copper Mark framework, reaffirming our commitment to continually pursue best practices based on international standards for responsible mining. Copper is essential to a low-carbon future, and so it is incumbent upon us to ensure that we supply this critical natural resource in as sustainable manner as possible.”

Michèle Brülhart, Executive Director of the Copper Mark said, “As the world’s leading copper producing country, it is vital that production in Chile is conducted responsibly. That is why we are pleased to welcome Capstone Copper’s Mantos Blancos and Mantoverde operations in Chile to the Copper Mark. We will be working with these sites through the Copper Mark framework to support their commitment to provide responsibly produced copper and accelerate the clean energy transition.”

Joining the Copper Mark is one of the ways Capstone is embedding sustainability into its growth strategy. More information about Capstone’s performance can be found in its sustainability reports available here.


The Copper Mark is a new assurance framework to promote responsible practices and demonstrate the copper industry’s contribution to the United Nations Sustainable Development Goals. The Copper Mark uses a rigorous site-level assessment process to independently verify whether individual copper producing sites have responsible production practices.

The Copper Mark already covers two of the largest copper mines in the world, five producers in the biggest copper producing region in the world, and six of the ten largest companies producing copper. Over 20% of global copper is now produced by Copper Mark-assured sites.

The Copper Mark is built on a genuine commitment of the copper industry to responsible production as we aim to mitigate the environmental and social impact of the copper industry, and positively contribute to sustainable development goals and the green transition. The Copper Mark framework involves a robust three-year re-evaluation process at site-level for participants. Participants commit to continual improvement, building the management systems necessary to ensure ongoing legal compliance.

The Mantoverde Development Project (“MVDP”) represents a transformational expansion of our Mantoverde mine in Chile to process sulphide ore via a copper concentrator, in addition to the mine’s current oxide ore processing capabilities. The $870 million project is in the commissioning and ramp-up stage, with nameplate production levels expected to be achieved in Q3/2024, and is expected to drive significantly higher consolidated production at lower unit costs for Capstone Copper.
