The MCSA Mining Complex (“MCSA”) is located in northeastern Bahia State, Brazil, approximately 385 km north-northwest of the capital city of Salvador. MCSA consists of fully integrated mining operations and processing facilities, including the Pilar and Vermelhos underground mines and the Surubim open pit mine. Ore is processed using conventional crushing and flotation at the Caraíba Mill, located adjacent to the Pilar underground mine. A high-grade, clean concentrate grading 35% copper is shipped and sold locally to the Paranapanema Smelter and to international markets via the Port of Salvador.
The high-grade mafic-ultramafic mineral occurrences contained within the Curaçá Valley extend over 100 km in strike length. 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 exploration potential over approximately 164,000 hectares controlled by MCSA.
