Site Infrastructure Power Supply Site Water Management ▪ The MCB Project will comprise an underground mine and surface infrastructures. ▪ Estimated power demand of 12 MW to be sourced from the National Grid Corporation of the Philippines at San Esteban, Ilocos Sur. ▪ 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 site layout includes a process plant, ancillary facilities, and a general admin facility. ▪ 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. ▪ The containers will be stored in a laydown area near the port and delivered to the docking area once a vessel is available. ▪ Road (21 km) connecting the mine site to the highway and shipping port will be jointly developed by MMCI and the Provincial Local Government Unit. ▪ Additional towers and overhead transmission lines will be necessary to connect the grid to the project site. ▪ Current grid power from coal (60%), gas (18%), geothermal (10%), hydro (8%), wind & solar (2.6%) ▪ Alternative power sources may used as renewable energy projects become operational, including a geothermal and hydropower. ▪ 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.
