Effective 15 August 2017, the Company transferred its official seat from the Netherlands to London, United Kingdom. The Company’s shares are listed on the Toronto Stock Exchange (“TSX”) under the symbol MNO. During 2025, the Company completed its corporate conversion in the United Kingdom, changing its legal form from Meridian Mining UK Societas to Meridian Mining plc. The Company is currently engaged in the exploration and development of mineral deposits in Brazil, through its subsidiaries, Rio Cabaçal Mineração Ltda (“Rio Cabaçal”) and Meridian Mineração Jaburi S.A. (“Jaburi”). The Company’s head office is located at 8th Floor, 4 More London Riverside, London, SE1 2AU, United Kingdom. Business Overview Meridian is a resource development and exploration company with projects in Brazil. The Company signed a Purchase Agreement on 6 November 2020, to acquire the rights within the Cabaçal gold (“Au”) – copper (“Cu”) – silver (“Ag”) Volcanic Massive Sulphide (“VMS”) belt (“VMS Belt”), that included the historical Cabaçal Au-Cu-Ag mine (“Cabaçal”), and the separate Santa Helena Cu-Au-Ag, Zinc (“Zn”), and Lead (“Pb”) mine (“Santa Helena”) in the state of Mato Grosso, Brazil. The Company has separately secured additional licences across the project’s VMS Belt, and in the parallel Jauru and Araputanga greenstone belts to the west of Cabaçal. The Company also has non-core projects in the State of Rondônia, including the Espigão Cu-Au polymetallic (“Espigão”) project. Strategy Meridian’s vision is to create sustainable value for its stakeholders by developing and exploring for high quality resource assets. The Company is committed to being a responsible steward of the environment and building collaborative partnerships with communities, governments, and all other stakeholders for mutual success. The Company’s focus is on the resource development and exploration of Cabaçal. The Company is reviewing a dual listing on the London Stock Exchange Main Market under the Equity Share - Commercial Company designation to target exposure to both FTSE index inclusion, and the UK investment market. Group Outlook Our priorities are to focus on the potential of the Au-Cu-Ag at Cabaçal and Au-Cu-Ag & Zn potential at Santa Helena, which are both assets acquired through the Purchase Agreement with two private Brazilian companies (detailed below). The priority focus is to advance and complete the feasibility study on the Cabaçal project whilst continuing exploration and resource definition work at the Santa Helena project. In March 2025, the Company published a Pre-Feasibility Study on Cabaçal (“PFS”). During the year ended 31 December 2025, the Company commenced the next phase of studies by initiating Cabaçal’s Feasibility Study. This involves detailed engineering, economic, metallurgical and final environmental studies. An infill drilling programme of the Cabaçal deposit was undertaken and completed on 7 October 2025. The Company is conducting a separate drilling programme at Santa Helena to evaluate potential for a second open- pit development. The Company has initiated a metallurgical programme for Santa Helena based on the historical metallurgical data and flowsheet, with the inclusion of oxide-transitional metallurgical testing, and also with the addition of a gravity circuit for the recovery of any free gold mineralisation. Regional exploration along the VMS Belt is planned to progressively cover over 50km of strike of the prospective geology that is held by the Company under licence. The aim is to identify additional Cu-Au-Ag systems for follow up drilling. The Company will continue to develop its Executive Management and Brazilian teams to meet business needs for the continual growth of the principal asset of Cabaçal. 31 December 2025 3 2026 Business Outlook The Company continued to advance the Cabaçal and Santa Helena projects during 2025. Key objectives for the Company during the year included initiating Cabaçal’s Feasibility Study (which is currently underway), granting of the Preliminary License (granted 31 October 2025 and formalised 3 November 2025), and the future publication of the inaugural Santa Helena resource statement. In parallel, the Company is advancing the greater VMS Belt’s exploration licenses to keep them in good standing. The Company is looking to achieve this during a period when gold and copper prices remain robust and there is an increased interest in natural resource equities occurring. Performance Review The review should be read in conjunction with the audited financial statements and notes. The Board assesses the performance of the Company and its senior management by evaluating, on a quarterly basis, the level of cash holdings of the Company, operational achievements, management of costs and capital expenditures. All amounts are in United States (“US”) dollars and all units of measurement are expressed using the metric system, unless otherwise stated. References to “$”, “US$” or “dollars” are to US dollars, and references to “C$” are to Canadian dollars. Financial key performance indicators Financial Performance highlights Results of Operations The consolidated financial statements reflect the financial performance of the Group for the year ended 31 December 2025. During the year ended 31 December 2025, the Group incurred a total comprehensive loss of $17,047,361 as compared to a total comprehensive loss of $20,013,091for the year ended 31 December 2024. Operating expenses for the Group totalled $18,179,398 for the year ended 31 December 2025, compared to $17,788,926 for the year ended 31 December 2024. The main variances were primarily driven by higher engineering and study expenditures related to the advancement of the Feasibility Study, together with the recognition of share- based compensation arising from stock option grants made during the year. The Company expenses costs incurred in relation to the Cabaçal Project, including engineering and feasibility-related expenditures, as they are incurred, in line with its accounting policy under IFRS 6. Although the Cabaçal Project has reached the pre-feasibility stage, key milestones — including completion of the definitive feasibility study, obtaining the installation licence, securing project financing and a final investment decision — remain outstanding. Accordingly, management has determined that the criteria to commence capitalisation of development expenditures have not yet been met, and such costs continue to be recognised as expenses. Operating expenses with significant balances or significant movements include: • Exploration and evaluation costs increased to $9,372,104 (2024 - $8,722,577). The variance was primarily due to higher expenditures compared to the prior year, driven by increased engineering and technical study costs associated with the advancement of the Feasibility Study, as well as higher costs related to drilling campaigns at Santa Helena, Cabaçal, and for regional exploration. • General and administration expenses increased to $4,541,151 (2024 - $2,977,345). The variance reflects incentive-based compensation approved by the Board and higher payroll, employee benefit, and travel expenses supporting the advancement of the Cabaçal project and corporate activities. • Professional fees increased to $1,864,936 (2024 - $724,759). The increase is mainly related to financial advisory fees and the legal fees related to the conversion to a plc. • Share based compensation of $2,134,179 (2024 – $118,834). Variance related to the issuance of 8,025,000 stock options in 2025, compared to 780,000 options issued in 2024. • Foreign exchange gain of $586,343 (2024 – loss of $795,756). The foreign exchange gain was incurred mainly due to fluctuation of exchange rates related to the translation of the Canadian dollars cash balances to US dollars during 2025 compared to 2024. 4 The results for the year ended 31 December 2025, included other comprehensive loss of $44,717 (2024 – loss of $1,778,186), comprised of foreign currency translation differences, primarily arising from the translation of the Company’s Brazilian operations. These differences result from translating the financial statements of subsidiaries with a BRL functional currency into the Company’s USD presentation currency, with assets and liabilities translated at the closing rate and income and expenses at average rates, in accordance with IAS 21. The movement in the period reflects fluctuations between average and closing exchange rates. Detailed breakdowns of exploration costs for the year ended 31 December 2025 are provided in the notes to the consolidated financial statements. Non-financial key performance indicators The Board establishes targets to maintain and improve the operational performance of the Group. These targets primarily focus on the exploration and development of mineral properties, environment and corporate structure, areas which the Board considers important for the short and long-term success of the Group and its operations. Cabaçal Highlights On 10 March 2025, the Company announced the positive results of the Preliminary Feasibility Study (“PFS”) led by Ausenco do Brasil Engenharia Ltda and Ausenco Engineering Canada ULC, supported by GE 21 Mineral Consultants Ltd for the advanced Cabaçal gold-copper-silver deposit in Brazil. In preparation for the commencement of the Cabaçal detailed feasibility study, the Company announced that it is expanding the team for the engineering and potential financing and development of the Cabaçal mine project. On 8 May 2025, the Company announced that it has appointed Ausenco do Brasil Engenharia Ltda to undertake the Definitive Feasibility Study for its advanced Cabaçal Au-Cu project in Mato Grosso, Brazil. Meridian also signed a Corporate Agreement with Aurubis AG to facilitate a technical exchange to optimize Cabaçal’s Cu + Au-Ag sulphide concentrates.
