The MCSA Mining Complex consists of fully integrated underground mining, open pit mining and processing facilities. The high-grade mafic-ultramafic mineral occurrences contained within the Curaçá Valley extend over 100 km in strike length. Current operations include the integrated mining operations of the Pilar underground mine, the Surubim open pit mine and the Vermelhos underground mine, currently under development. Ore is processed using conventional crushing and flotation at the Caraíba Mill, located adjacent to the Pilar underground mine. Near mine and regional exploration activities are concentrated in three under-explored mineral districts: the Pilar District, located in the south of the Curaçá Valley, the centrally located Surubim District and the northern Vermelhos District. Combined, these districts provide excellent near-mine and regional exploration potential over approximately 129,000 hectares controlled by MCSA.
The MCSA Mining Complex is located in northeastern Bahia State, Brazil, approximately 385 km north-northwest of the capital city of Salvador. High-grade clean concentrate grading 35% copper is shipped and sold locally to the Paranapanema Smelter or to international markets via the Port of Salvador.
