We are ERO, a mining company born in the heart of Brazil that has grown to bring more strength and energy to the world—a strength that drives productive sectors and contributes to the development of different regions. Since 1979, when it began operations at the Caraíba unit, the company has been consolidating its presence in the Brazilian mineral sector, expanding into the gold mine in Xavantina and advancing the implementation of the Tucumã unit—which stands out as one of the country's main copper production hubs. Our growth is driven by exploration expertise, which helps extend the life of our mines and advance new projects, such as the Furnas Project in Pará.
