MERIDIAN MINING PLC ANNOUNCES RESULTS FROM FIRST UNITED KINGDOM PLACING

Meridian Mining PLC has raised gross proceeds of 22.5 million pounds sterling (approximately $30.4-million (U.S.)/$41.6-million (Canadian)) pursuant to its non-pre-emptive placing of new ordinary shares announced on April 27, 2026.

Gilbert Clark, chief executive officer, commented: "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 Cabacal, 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 have been placed by Stifel Nicolaus Europe Ltd., Joh. Berenberg, Gossler & Co. KG, and Peel Hunt LLP at a price of 92.0 pence per placing share ($1.70 (Canadian) per placing share). Stifel is acting as sole global co-ordinator 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 United Kingdom 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 for up to 2.5 million pounds sterling at the issue price (approximately $3.4-million (U.S.)/$4.6-million (Canadian)). The retail offer remains open until 11:59 p.m. on April 30, 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 and the commencement of dealings in the ordinary shares on the London Stock Exchange are expected to occur at 8 a.m. on May 1, 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 Toronto Stock Exchange.

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

We seek Safe Harbor.
