ANTOFAGASTA RELEASES TAX REPORT

As part of its commitment to transparency, Antofagasta plc ("Antofagasta" or the "Company") has published a series of reports on its contributions to stakeholders. The Company announces today that it has published a standalone report on its tax payments in respect of 2022 ("Tax Report"). The report provides detailed information about the nature of the taxes paid by the Company and the amounts paid. The total tax charge for the year was $603.5 million, of which almost 100% was in Chile.

Antofagasta plc CEO, Iván Arriagada said: "At Antofagasta, our focus lies in developing mining for a better future, and that's why we prioritise transparently reporting our contributions to the country's progress and the well-being and development of the communities residing around our operations and projects.

"Mining not only stimulates economic activity, creates employment, and generates tax revenue for the benefit of all, but also enables us to actively contribute to skill development, technological integration and innovation, the growth of supplier companies, and community investments."

Antofagasta plc CFO, Mauricio Ortiz said: "We are proud to present our second Tax Report, which clearly reflects how the mining we do at Antofagasta translates into value generation for all our stakeholders and it aligns with our aim to be recognised as an industry leader for the transparency of our reporting.

"Being open and transparent about our tax payments, our wider economic contribution and our position with respect to a wide range of sustainability considerations are central to how we make decisions and perform our work, which in turn is fundamental to how we engage with our stakeholders."
