Site Infrastructure Power Supply Site Water Management ▪ The MCB Project will comprise an underground mine and surface infrastructures. ▪ The site layout includes a process plant, ancillary facilities, and a general admin facility. ▪ The Project’s calculated 12-megawatt power demand will be sourced from the nearest substation of the National Grid Corporation of the Philippines at San Esteban, Ilocos Sur. ▪ Concentrates will be transported from the plant site to the port facility by trucks using lined containers, via the 21-km main access road that is to be constructed. ▪ Although existing power lines are available, it is expected that additional towers and overhead transmission lines will be necessary to cater operations. ▪ A freshwater impoundment and the underground water collection pond with estimated capacity of approximately 100,000m3 and 500,000m3, respectively, will be constructed to support site operations. ▪ The containers will be stored in a laydown area near the port and delivered to the docking area once a vessel is available. ▪ Alternative power sources may be tapped in the future when various renewable energy projects near the area become operational, including a geothermal power project and two other hydropower projects. ▪ Road alignment from mine site to port will be jointly developed by MMCI and the Provincial Local Government Unit. CLA Announcement dated 01 December 2021 and 19 October 2023 Celsius Resources - Corporate Presentation July 2025 ▪ A water treatment plant or clarifier will be installed after the collection dam to remove the impurities from the contact water before discharging to the Pasil River. ▪ The operation will use minimal fresh water with an average demand of 0.02m3/s, most of which will be recycled. 16 MCB Project | Project Financing Status ▪ Bridging Loan agreement signed with Maharlika Investment Corporation, the Philippines’ sovereign wealth fund, for a bridge loan facility of USD 76.4 million. ▪ Maharlika Investment Corporation is a Philippine Government owned and controlled corporation mandated to manage the sovereign wealth fund of the Philippines. Its mission includes driving long-term national development by fostering job creation, accelerating poverty reduction, and promoting economic growth while achieving optimal investment returns. ▪ The Facility is intended to fully finance the updating of the Company’s feasibility study (“FS”) and Front-End Engineering Design (“FEED”), and partially funding early works development activities, including main access road in coordination with the Kalinga Provincial Government and skills-based training for the Balatoc community. • The proceeds of the Facility marks a critical milestone in the Project’s funding, enabling immediate commencement of work with the initial funding amount of USD10 Million. The first drawdown from this facility occurred in June. • Over the next few months, Celsius will focus on delivery of a project financing package with funds expected to be received from late this year. • MMCI has a number of active mandates with finance groups including MIC to secure equity or debt & equity funding for MCB.
