Successful Fundraise

Atalaya Mining (LSE: ATYM) is pleased to announce that, further to the announcement made on 27 January 2026, it has successfully placed 12,730,000 new ordinary shares in the Company ("Ordinary Shares") with new institutional investors and existing shareholders (the "Placing Shares") at a price of £10.00 per Placing Share (the "Placing Price") raising gross proceeds of £127.3 million.

Concurrently with the Placing, eligible retail investors have subscribed in the offer made by the Company via RetailBook for a total of 270,000 new Ordinary Shares (the "RetailBook Offer Shares" and, together with the Placing Shares, the "Offer Shares") at the Placing Price (the "Retail Offer" and, together with the Placing, the "Fundraise") raising gross proceeds of £2.7 million.

Mike Amitage, a non-executive director of the Company, subscribed for 4,000 new Ordinary Shares as part of the Retail Offer. Following Admission, Mr Armitage will hold 4,695 Ordinary Shares.

In total, 13,000,000 Offer Shares have been subscribed for at the Placing Price raising gross proceeds of £130 million (equivalent to approximately €150 million). The Offer Shares represent, in aggregate, approximately 9.2% of the Company's issued Ordinary Share capital prior to the Fundraise.

Both the Placing and the Retail Offer were significantly oversubscribed, receiving strong support from existing and new investors, allowing the Company to broaden its institutional following and market support.

Alberto Lavandeira, CEO, commented:

"We are pleased to announce the successful closing of this capital raise. This represents a significant milestone for Atalaya and will enable us to accelerate our growth projects in Spain, while further strengthening our balance sheet and enhancing our financial flexibility for the development of Touro.

The successful completion of this raise reflects the confidence our investors have in our strategy, our team, and the long‑term value embedded within our portfolio. We would like to express our sincere appreciation to both new and existing shareholders for their continued support as we advance our projects in the Riotinto District and position Atalaya to capitalise on positive copper market fundamentals."
