Ero Copper Corp. is a Canadian base metals mining company that primarily operates in Brazil, focusing on the production and sale of copper concentrate, as well as gold and silver by-products. The company's core assets include the Caraíba Operations (formerly the MCSA Mining Complex) located in the Curaçá Valley of Bahia State, which features fully integrated underground and open-pit mining and processing facilities. Additionally, Ero Copper operates the Tucumã Project (formerly Boa Esperança), an iron oxide copper-gold (IOCG) deposit in Pará State, and the Xavantina Operations (formerly NX Gold), a gold and silver mine in Mato Grosso State. The company generates the vast majority of its revenue from copper production, with its Caraíba and Tucumã operations accounting for nearly 80% of total revenues, while the Xavantina gold operations contribute the remainder.
