Notes

^* The full text of the resolutions passed at the Meeting is available in the Notice of Meeting on the Company's website at Shareholder Meeting Information - Atalaya Mining. Resolution 13b. was withdrawn from the Meeting.

^** Two-thirds majority required.

^# Resolution 13b. was withdrawn from the Meeting due to lack of shareholder support.

^## In accordance with Spanish law, abstentions have been included in the calculation of total votes cast and therefore impacted the outcome of the resolution by effectively reducing the level of support expressed as a percentage.

The total number of shares in issue in the capital of the Company on 24 June 2025 was 140,759,043 ordinary shares of €0.09 nominal value each. Votes were cast in respect of 43.39% of the issued share capital.

In accordance with Listing Rule 6.4.2 copies of the resolutions passed at the Meeting, other than resolutions constituting ordinary business, will shortly be available for inspection via the Financial Conduct Authority's Electronic Submission System at https://data.fca.org.uk/#/nsm/nationalstoragemechanism

Following the extensive shareholder consultation exercise that was undertaken in relation to voting on the remuneration-related resolutions at the Company's 2024 AGM, the Board is pleased that Resolution 7 (approval of directors' remuneration policy) received 96.35% votes in favour at this year's AGM.

However, the Board notes that more than 20% of proxy votes cast were against Resolution 5a (re-election of Jesús Fernández), Resolution 6 (approval of directors' remuneration report), Resolution 8 (approval of grant of awards pursuant to the long-term incentive plan), and Resolution 9 (approval of the grant of a one-off transitional award to the Chief Executive Officer).

Provision 4 of the UK Corporate Governance Code (the "Code") provides that where 20% or more of votes have been cast against the board recommendation for a resolution, the Company should explain what actions it intends to take to consult shareholders in order to understand the reasons behind the result.

A shareholder engagement exercise was conducted in the fourth quarter of 2024 and feedback received from those who participated was taken into account. The Board will continue to reflect on the concerns raised and will consider what further consultation with shareholders would be beneficial. An update will be provided in due course as required by the Code.
