Meridian Background

Meridian is focussed on the development of gold-copper projects in Brazil, including its core asset, the advanced stage Cabaçal gold-copper project. Historically, Cabaçal was previously operated as a small selective underground mine by BP Minerals and RTZ (Rio Tinto) in the 1980s and 1990s. On 31 March 2025, Meridian released a Pre-feasibility Study technical report entitled: "Cabaçal Gold-Copper Project NI 43-101 Technical Report and Pre-feasibility Study" (the "2025 PFS") which outlined a project that combined low technical complexity with attractive economics. The 2025 PFS reported an open pit operation with a low All-in-Sustaining-Cost of USD 742 per ounce gold equivalent and a production profile of 141,000-ounce gold equivalent over an initial 10 year mine life, driven by high metallurgical recovery, a low life-of-mine strip ratio of 2.3:1, and the low operating cost environment of Brazil. Subject to the qualifications and assumptions contained in the 2025 PFS, Cabaçal is projected to deliver a post-tax IRR of 61.2% and NPV of USD 984 million at a discount rate of 5% from a pre-production capital cost of USD 248 million (assuming a metals price scenario of USD 2,119 per ounce of gold, USD 4.16 per pound of copper, and USD 26.89 per ounce of silver).

Cabaçal's Mineral Reserve is relatively shallow, with medium-soft ore and a high-grade gold-copper zone close to surface. This makes the open pit mining and processing technically simple, fast and profitable. Construction is expected to last 2 years, with the initial capital repaid in just 17 months of operation using the base case economic assumption in the 2025 PFS. The base case post-tax NPV at a 5% discount divided by capex is c.4.0 times, which compares favourably to peers.

The Company, led by CEO Gilbert Clark, has a strong and experienced Board and Executive team who are well prepared to advance Cabaçal towards construction and production. In Brazil, Cabaçal is managed by an experienced Brazilian team of mining engineers, geologists, environmental engineers and administrative personnel. They contribute decades of experience towards exploring, permitting, building and expanding mines within Brazil's low-cost operational environment.

The Company is preparing for development of the Cabaçal mine subject to a positive final investment decision and, to that end, the Company has ordered certain long lead items and planning of pre-construction civil works is ongoing. The Company continues to advance Cabaçal's Definitive Feasibility Technical Study (the "DFS"), alongside its engineering contractors and is targeting publication of the DFS in Q4 2026.

Since 2021, Meridian has been conducting ongoing district-scale exploration and resource development programmes along the Cabaçal VMS Belt. Within the extensive mineral licence area, the Company is developing a hub-and-spoke strategy. The Company's Santa Helena Central project is next in line for further drilling, development studies, and near-mine exploration to test expansion potential. Regional geophysical and geochemical surveys continue across the wider 50 km-long Cabaçal Greenstone Belt, generating additional targets, and are planned to extend into the neighbouring Araputanga and Jauru Greenstone Belts.

Fundraising Highlights

·    The Fundraising will be conducted via the issue of new Ordinary Shares and consists of:

o  a non-pre-emptive placing of new Ordinary Shares to institutional investors at the Issue Price to raise gross proceeds of up to approximately £22.5 million (approximately USD30.4 million or CAD41.6 million) (the "Placing"); and

o  a non-pre-emptive retail offer through Retail Book Limited's ("RetailBook") partner network of investment platforms, retail brokers and wealth managers, subject to such partners' participation in the Fundraising at the Issue Price to raise gross proceeds of up to approximately £2.5 million (approximately USD3.4 million or CAD4.6 million) (the "Retail Offer").

·   The Issue Price represents a discount of approximately 5.6 per cent to the closing price of CAD1.80 per share on 24 April 2026 on the TSX.

·   The Placing is being conducted through an accelerated bookbuild (the "Bookbuild") which will be launched immediately following the release of this announcement.

·   The timing of the closing of the Bookbuild, the number of new Ordinary Shares to be placed and allocations will be agreed between the Global Co-ordinator and the Company following completion of the Bookbuild and will be announced as soon as practicable on a Regulatory Information Service.

·    A separate announcement will be made shortly providing further details of the Retail Offer.

·    The Company intends to use the net proceeds from the Placing, along with its existing cash, primarily to fund development activities at the Cabaçal project, including deposits for long lead items, advanced infrastructure, civil works, working capital and corporate general and administrative costs. The Company intends to use the net proceeds from the Retail Offer for additional corporate general and administrative costs.

·    In connection with the Fundraising, the Company has agreed to lock-up arrangements for a period of 90 days from Admission.

·    Admission, and the commencement of dealings in the Ordinary Shares, 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.

·    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.

·    Additional details in relation to the Fundraising are set out in the Prospectus.

·  The Company has engaged Stifel Nicolaus Europe Limited as Sponsor, Global Co-ordinator and Joint Bookrunner and Joh. Berenberg, Gossler & Co. KG, London Branch and Peel Hunt LLP as Joint Bookrunners.

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.

This announcement refers to certain non-IFRS measures, in particular All-in-Sustaining-Cost.
