Atalaya Mining Plc.

("Atalaya" or "the Company")

Voluntary Delisting from the Toronto Stock Exchange

Atalaya Mining plc ("Atalaya" or the "Company") (AIM: ATYM; TSX: AYM) announces that it has applied for a voluntary delisting of its ordinary shares from the Toronto Stock Exchange (the "TSX") to be effective as of the closing of trading on 7 March 2023. Ordinary shares in the Company will continue to trade on the AIM market of the London Stock Exchange under the symbol "ATYM".

Over the past three years, daily trading activity in the Company's ordinary shares on AIM has increased materially and, in the last twelve months, has accounted for around 99% of the aggregate trading volume on both platforms. As a result of the minimal trading volumes on the TSX, the Company believes that the financial costs and administrative requirements associated with maintaining the TSX listing are no longer justified.

Shareholder approval is not required for the delisting because the Company's shares trade on AIM, which is an acceptable alternative market in accordance with Section 720(b) of the TSX Company Manual.

Additional Information for Shareholders on the Canadian Register

Following the delisting from the TSX, Canadian shareholders wishing to trade their shares on AIM will require that such shares are made eligible to be transferred and settled though CREST, the United Kingdom ("UK") based share transfer and settlement system. Shares cannot be transferred and settled through CREST until a shareholder's CDS Participant broker or the shareholder, if the shares are held in certificated form, as applicable, validly instructs Computershare Trust Company of Canada ("Computershare") to arrange for the shares to be held by a CREST participant broker. This can be done by completing a 'Register Removal Request (Canadian Register to United Kingdom Register) form, with valid CREST participant account details, and submitting such form to Computershare via email at [email protected].

For any questions on this process please contact Computershare's global transaction unit by phone at +1 (877) 624-5999. The Company intends to maintain CDS eligibility for its shares until 10 April, 2023 in order to provide Canadian shareholders with time to complete the process contemplated above.

The Company encourages shareholders holding shares in Canadian brokerage accounts to contact their brokers to confirm how they may hold and trade in Atalaya's shares either through the holding of a certificated share or UK depositary interests.
