We hold projects at various stages of the mining lifecycle—from greenfield development through to full-scale operations—and employ over 2,100 professionals nationwide, all committed to our purpose. Currently, we operate three iron ore mines in Minas Gerais: Baratinha and Mongais Mines, part of the Baratinha Complex, and Pedra Branca Mine. Our first iron ore operation, Baratinha Mine in the Vale do Aço region, began operations in 2014 and features a wet beneficiation plant with an annual capacity of 2.5 million tons. In 2024, the Mongais project entered operation, featuring dry processing capacity of 1.5 million tons per year, increasing the Baratinha Complex’s total annual capacity to 4.0 million tons. In João Monlevade and Itabira (MG), the Pedra Branca project commenced operations in Q3 2025\. The project holds 130 million tons of mineral resources, including 33 million tons of high-grade material, and is expected to reach full-capacity production of 2.0 million tons per year, exclusively via dry processing. Additionally, Bemisa operates a pilot-scale gold project in Água Azul do Norte, Pará State, near the Carajás polymetallic district. Developed from the greenfield stage, this project does not use tailings dams for waste disposal and employs predominantly local labor. We believe in the potential of Brazilian mining and are committed to integrating sustainability into our operations, generating socioeconomic development across all regions where we operate.
