Proposed Re-domiciliation and Notice of EGM

Atalaya Mining Plc (AIM: ATYM) is pleased to announce its intention to re-domicile the Company by transferring its registered office from the Republic of Cyprus to the Kingdom of Spain ("Proposed Re-domiciliation").

This change in corporate structure is subject to shareholder approval and regulatory consents. The Company is convening an Extraordinary General Meeting ("EGM") to consider and, if thought advisable, to approve the resolutions which are necessary to approve the Proposed Re-domiciliation. If approved, the Proposed Re-domiciliation is expected to be completed before end of May 2024.

Rationale for the Proposed Re-domiciliation

The re-domiciliation is being proposed as the incorporation in Cyprus no longer reflects the Company's geographic and strategic focus, and therefore represents a legacy structure for the Company.

The Proposed Re-domiciliation follows the Company's announcement on 13 November 2023 confirming its intention to move to the Main Market of the London Stock Exchange ("Step-up"). In the event the Step-up occurs, the Proposed Re-domiciliation also opens the possibility for the Company to be eligible for inclusion in the FTSE UK Index Series (subject to other eligibility criteria being satisfied at the time of application), which the Company believes would be in the interest of all its shareholders.

The proposed Re-domiciliation and the Step-up are independent of each other, and neither is conditional upon the other occurring.

Notice of EGM

The Company will host an EGM on Tuesday, 12 December 2023 at 11:00 am GMT at Hamilton House, 1 Temple Avenue, London EC4Y 0HA to consider the Proposed Re-domiciliation and related matters as a consequence of the Proposed Re-domiciliation.

A circular, incorporating the Notice of EGM and further background and information on the Proposed Re-domiciliation, together with forms of proxy are available on the Company's website at www.atalayamining.com.

Shareholders on register on 14 November 2023 are eligible to attend the meeting and vote at the EGM and should refer to the voting instructions set out in the Notice of EGM.

Expected Timetable

• The Effective Date of the Re-domiciliation will be announced to a regulatory information service following receipt of all required approvals.

If the Proposed Re-domiciliation is approved by shareholders and subsequently implemented:

• Atalaya's corporate seat and registered office will be transferred from the Republic of Cyprus to the Kingdom of Spain;
• Atalaya will no longer be governed by the laws of the Republic of Cyprus;
• Atalaya will continue to exist as a legal entity governed by Spanish law; and
• Atalaya Mining plc's name will change to Atalaya Mining Copper, S.A.

Alberto Lavandeira, CEO of Atalaya, commented:

"The decision to re-domicile is consistent with our strategic focus on broadening our shareholder base and creating further shareholder value. We believe this move, along with our intention to move to the Main Market of the London Stock Exchange, position the Company for continued growth at a time when investor interest in copper and the related energy transition thematic continues to accelerate."
