Notice for Holders of Physical Share Certificates

Atalaya Mining (LSE: ATYM) announces that alternative arrangements have now been implemented to assist the holders of Atalaya ordinary shares represented by physical certificates as at 9 January 2025 ("Certificated Holders") to convert their shares into electronic form represented by CREST Depositary Interests ("CDIs").

All ordinary shares represented by physical certificates as at 9 January 2025 have now been converted into electronic form and are now represented by CDIs. Upon the completion of the transfer described below, the conversion to CDIs will allow Certificated Holders to trade their Atalaya ordinary shares and receive the 2024 final dividend (which was paid to holders of CDIs on 23 July 2025) and any future dividend payments.

Certificated Holders are asked to submit a transfer request form to The Law Debenture Trust Corporation, who will effect the transfer of CDIs to a CREST member nominated by them.

This notice follows the Company's announcement on 6 January 2025 where Certificated Holders (whose holdings of ordinary shares together represent less than 0.97% of the Company's share capital) were recommended to present their physical certificates to Iberclear for conversion into shares represented by book entries.
