Result of Retail Offer

Meridian Mining plc (LSE/TSX: MNO), an exploration and development company focused on the advanced stage Cabaçal gold-copper project, announced on 27 April 2026 that it has applied for admission of its Ordinary Shares to the equity shares (commercial companies) category of the Official List of the FCA and to trading on the Main Market for listed securities of the London Stock Exchange (together, "Admission") as well as an equity offering of new ordinary shares in conjunction with the Retail Offer.

The Company is pleased to announce that the Retail Offer successfully completed and closed at 23.59 p.m. on 30 April 2026 and that it has conditionally raised approximately GBP2.5M (approximately USD3.4M / CAD4.6M) in the Retail Offer through the issue of 2,717,391 new Ordinary Shares at the Issue Price of 92.0 pence per Ordinary Share (CAD1.70 per Ordinary Share).

Following the close of the Retail Offer, the Company has conditionally raised gross proceeds of approximately GBP25.0M (approximately USD33.6M / CAD46.3M) via the Fundraising. The Company will therefore be required to issue and allot a total of 27,173,912 new Ordinary Shares to satisfy the Fundraising.

Capitalised terms used in this announcement shall, unless defined in this announcement or unless the context provides otherwise, bear the same meaning ascribed to such terms in the launch announcement.

Admission and Total Voting Rights

Application will be made to the London Stock Exchange for the 485,513,514 Ordinary Shares to be admitted to the equity shares (commercial companies) category of the Official List of the FCA and admitted to trading on the Main Market for listed securities of the London Stock Exchange. Admission is expected to take place and dealings in the Ordinary Shares are expected to commence at 8.00 a.m. on 1 May 2026, at which time it is also expected that the Ordinary Shares will be enabled for settlement in CREST.

Immediately following Admission, the issued share capital of the Company is expected to comprise 485,513,514 Ordinary Shares. Each Ordinary Share has one voting right and no Ordinary Shares are held in treasury. From Admission, this figure may be used by shareholders as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

Neither past performance nor any forecasts should be considered a reliable indicator of future results.
