Notes to the poll results

1.            Any proxy votes that were at the discretion of the Chairman are included in the total of "votes for" each resolution.

2.            Percentages of votes for and votes against each resolution are included on the basis of votes cast and therefore exclude abstentions.

3.            The Company had in issue 985,856,695 Ordinary Shares carrying one vote each, and 2,000,000 5% Cumulative Preference Shares carrying 100 votes each. Accordingly, the total number of votes available was 1,185,856,695 votes and the total number of votes available excluding the controlling shareholders was 350,086,090 votes at the Annual General Meeting.

4.            "Votes Cast as % of Issued Share Capital" represents the percentage of votes cast as a percentage of all votes that could have been cast on the resolution.

These results have been published on the Company's website (www.antofagasta.co.uk).

In accordance with Listing Rule 6.4.2, copies of resolutions 18, 19, 20, 21 and 22 passed at the Annual General Meeting will be submitted to the National Storage Mechanism today and will shortly be available for inspection at https://www.fca.org.uk/markets/primary-markets/regulatory-disclosures/national-storage-mechanism.
