Antofagasta will host a virtual Capital Markets Day today at 2pm GMT followed by Q&A.

The event will be hosted by Iván Arriagada, Chief Executive Officer, and will include presentations from Antofagasta's senior management.

Iván Arriagada, CEO, commented, “Antofagasta is a pure play copper producer with high quality assets in Chile, supported by a team that delivers reliably and responsibly through the cycle. Today you will hear from our team as we discuss how we mine and what we are doing to progress the future of mining in a way that is sustainable and delivers value for all our stakeholders. You will also hear about the embedded growth options we have in our portfolio and the levers we have to unlock that growth, in a value-accretive way, over many years to come. We are excited about the future of Antofagasta and invite you to join us today.”

Key highlights to be presented today include:

Responsible and reliable producer creating real social value

•  90% of water used in our operations is expected to be from seawater or recirculated water by 2025
• 100% of our energy requirement in operations is planned to be from renewables by the end of 2022
• Building out new ways of mining using autonomous trucks, remote operating centres and establishing a Digital Academy so our employees can work in a safer and healthier environment
• Strong social commitments, working with our local suppliers and communities

Unlocking embedded growth

• Five-year production to potentially reach approximately 900,000 tonnes of copper by 2026 if the Second Concentrator project at Centinela is approved by the end of 2022
• 18 billion tonnes of mineral resources with 7 billion tonnes in the Centinela mining district and 6 billion tonnes at Los Pelambres
• A proprietary primary sulphide leach technology which, if proved successful, could unlock previously uneconomic tonnes from lower grade chalcopyrite ore
• 2022 capital expenditure guidance will be given in 4Q Production Report, together with mine-by-mine production and cost guidance, once a review of the Los Pelambres Expansion project is finalised
• Expanded capital allocation framework now includes climate change factor
