Intention to Move from AIM to Main Market

Atalaya Mining Plc (AIM: ATYM) is pleased to announce its intention to apply for the Company's ordinary shares ("Ordinary Shares") to be admitted to the premium listing segment of the Official List maintained by the Financial Conduct Authority ("FCA") ("Official List") and to trading on the London Stock Exchange plc's ("London Stock Exchange") main market for listed securities ("Main Market") (together, "Admission").

Since restarting operations at Proyecto Riotinto in 2016, Atalaya has become a leading European producer of copper, which is a key commodity for economic growth and the energy transition. Atalaya has assembled a portfolio of growth projects across several world-class mineral districts in Spain and maintains a sustainable dividend policy. In order to build on this success, Atalaya's Board of Directors believes that the move to the Main Market would further enhance the Company's corporate profile and broaden its appeal to new institutional investors.

Atalaya does not intend to raise any funds or offer any new securities in connection with Admission or the publication of the related prospectus. The Admission will be effected through an introduction of the Company's existing Ordinary Shares.

Admission is subject to the approval by the FCA of a prospectus and the Ordinary Shares being admitted by the FCA to the premium listing segment of the Official List and by the London Stock Exchange to trading on the Main Market. Subject to the satisfaction of these conditions, Admission is expected to occur before the end of December 2023. Accordingly, the Company hereby gives notice of the intended cancellation of trading of its Ordinary Shares on AIM in accordance with Rule 41 of the AIM Rules for Companies. The Company's listing on AIM is expected to be to be cancelled before the end of December 2023.

Atalaya will make a further announcement on the status of the proposed applications for Admission, together with the timeline for Admission, in due course.

Admission is not expected to be conditional upon shareholder approval. Atalaya shareholders should consult their own professional advisors regarding the consequences of Admission on their personal tax position.

Peel Hunt LLP is acting exclusively as sponsor to the Company and no one else in connection with Admission.

Alberto Lavandeira, CEO of Atalaya, commented:

"In the last eight years we have established Atalaya as one of Europe's leading copper producers, achieving scale, growth and consistency. At the same time, copper has become widely regarded as a strategic metal due to its important role in the energy transition.

We are committed to building upon the significant growth we have achieved to date and our intention to seek admission to the premium listing segment of the Official List reflects our confidence in our future prospects, our expanding investor base and our ambition to become a multi-asset producer with a portfolio of sustainable, scalable and low-risk operations."
