The Company signed a Purchase Agreement on November 6, 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 investors and 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 principal focus is on the resource development and exploration of Cabaçal. 1 Management’s Discussion and Analysis Corporate Outlook The Company’s strategic priorities remain focused on advancing the development potential of its two principal assets: the Cabaçal Au-Cu-Ag Project and the Santa Helena Au-Cu-Ag & Zn Project. Both assets were acquired through the Purchase Agreement with two private Brazilian companies (detailed below) and represent the core of the Company’s near-term and medium-term growth strategy. The primary focus for the period continued to be the advancement and completion of the Feasibility Study for the Cabaçal Project. This work follows the successful publication of the Cabaçal Pre-Feasibility Study (“PFS”) in March 2025. The Feasibility Study encompasses basic engineering, economic analysis, metallurgical testwork, and final environmental studies and is targeted for completion in Q4 2026. The infill drilling programme required to support the Feasibility Study was completed on October 7, 2025. In parallel, the Company has conducted a dedicated drilling programme at Santa Helena to evaluate the potential for a second open-pit development. From the second quarter of 2026 and onwards, this programme transitioned to near-mine and regional exploration drilling. Metallurgical test work at Santa Helena is ongoing, with a specific focus on improving precious metal recoveries in the fresh rock zones of the deposit. Beyond the two principal deposits, the Company is undertaking regional exploration along the broader VMS Belt. Planned activities will progressively evaluate more than 50 kilometres of strike length across prospective geology held under licence. The objective of this programme is to identify additional Cu-Au-Ag systems that may support future resource growth and potential satellite development opportunities. The Company will also look to test the copper-gold potential of the Espigão project in Rondonia during 2026. To support these operational and strategic initiatives, the Company continues to strengthen its Executive Management team and expand its Brazilian operational capabilities. These efforts are aligned with the long-term development of the Cabaçal Project and the continued growth of the Company’s regional project portfolio.
