Meridian Mining plc Announces Results from first United Kingdom Placing

Toronto, Canada, 27 April 2026 / Newsfile / Meridian Mining plc (TSX: MNO), (Frankfurt/Tradegate: N2E0) (OTCQX: MRRDF) is pleased to announce that it has successfully raised gross proceeds of £22.5 million (approximately USD30.4 million / CAD41.6 million) pursuant to its non-pre-emptive placing of new Ordinary Shares announced on 27 April 2026.

Mr. Gilbert Clark, CEO, comments "We greatly appreciate the support from our existing and new shareholders who have placed the Company in a strong financial position just prior to the LSE's listing. Our messaging has never been clearer: near-term development then production from Cabaçal, expand Santa Helena Central to be the next mine, resource growth through belt-scale exploration programs; creating the next mid-tier gold and copper miner on the London Stock Exchange and the TSX. The opportunity of being the first mover into what we see as Brazil's and South America's most prospective gold and copper VMS belt is only at its naissance."

A total of 24,456,521 new Ordinary Shares ("Placing Shares") have been placed by Stifel Nicolaus Europe Limited ("Stifel"), Joh. Berenberg, Gossler & Co. KG ("Berenberg") and Peel Hunt LLP ("Peel Hunt") at a price of 92.0 pence per Placing Share (CAD1.70 per Placing Share) (the "Issue Price"). Stifel is acting as sole global coordinator and joint bookrunner in connection with the Placing. Berenberg and Peel Hunt are acting as joint bookrunners in connection with the Placing.

The Placing was significantly oversubscribed, receiving strong support from existing and new investors, allowing the Company to broaden its institutional following and market support particularly in the UK as it prepares to commence trading on the Main Market for listed securities of the London Stock Exchange.

Concurrent with the Placing, the Company is undertaking a retail offering to eligible retail investors (the "Retail Offer" and, together with the Placing, the "Fundraising") for up to £2.5 million at the Issue Price (approximately USD3.4 million / CAD 4.6 million). The Retail Offer remains open until 23:59 on 30 April 2026. The results of the Retail Offer will be announced in due course.

Admission of the 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"), and the commencement of dealings in the Ordinary Shares on the London Stock Exchange, is expected to occur at 8.00 a.m. on 01 May 2026 under the ticker MNO (ISIN: GB00BVPND783). There will be no conditional dealing prior to this date. Meridian's shares will be fully fungible between the London Stock Exchange and the TSX.

Immediately following Admission, the Company expects it would have a free float and liquidity that would make it eligible for inclusion in the FTSE UK Index Series, although inclusion remains subject to review by FTSE Russell.

Some statements in this announcement contain forward-looking information or forward-looking statements for the purposes of applicable securities laws. These statements address future events and conditions and so involve inherent risks and uncertainties, as disclosed under the heading "Risk Factors" in Meridian's most recent Annual Information Form filed on www.sedarplus.ca and under the heading "Risk Factors" in the Prospectus. Forward-looking statements and forward-looking information include, but are not limited to: the completion of Admission, the Placing and the Retail Offer; the proposed benefits of Admission; the issuance of the new Ordinary Shares; the intended use of proceeds from the Fundraising; the expected closing date of the Fundraising; the release of the DFS; and the proposed lifting of the TSX trading halt. Forward-looking statements are frequently characterized by words such as "anticipates," "may," "can," "plans," "believes," "estimates," "expects," "projects," "targets," "intends," "likely," "will," "should," "to be", "potential" and other similar words, or statements that certain events or conditions "may", "should" or "will" occur.

Forward-looking statements are based on the opinions and estimates of management at the date the statements are made and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of the Company and there is no assurance they will prove to be correct. Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include the satisfaction of the conditions acceptable to the Company; the Company receiving all requisite approvals in connection with Admission, the Placing and the Retail Offer, including the approval of the London Stock Exchange and the TSX; and market interest in the Placing and Retail Offer. The Company cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail. While these factors and assumptions are considered reasonable by Meridian, in light of management's experience and perception of current conditions and expected developments, Meridian can give no assurance that such expectations will prove to be correct.

Any forward-looking statement speaks only as of the date on which it is made and, except as may be required by applicable securities laws, each of Meridian, the Banks and all other persons disclaims any intent or obligation to update, supplement, amend or revise any forward-looking statement, whether as a result of new information, future events, or results or otherwise. The reader is cautioned not to place undue reliance on forward-looking statements. The forward-looking information contained in this announcement is expressly qualified by this cautionary statement.

Before subscribing for any Ordinary Shares, persons viewing this announcement should read the Prospectus and ensure that they fully understand and accept the potential risks associated with a decision to invest in the Ordinary Shares. No reliance may be placed for any purpose on the information contained in this announcement or its accuracy or completeness. This announcement does not constitute, or form part of, any offer or invitation to sell or issue, or any solicitation of any offer to acquire, whether by subscription or purchase, any Ordinary Shares or any other securities, nor shall it (or any part of it), or the fact of its distribution, form the basis of, or be relied on in connection with, or act as any inducement to enter into, any contract or commitment whatsoever.

Potential investors should not base their investment decisions on this announcement or any part of it. Acquiring securities to which this announcement relates may expose an investor to significant risk of losing some or all of the amount invested. Following Admission, the value of the Ordinary Shares could decrease as well as increase. Neither this announcement, nor the Prospectus constitute a recommendation concerning the Fundraising or with respect to any investment in Ordinary Shares. Potential investors should consult a suitably qualified and experienced professional adviser as to the suitability of an investment in Ordinary Shares for the person concerned.
