Nexa announces that its Peruvian affiliate, Nexa Resources Atacocha (“Atacocha”), will resume operations at the San Gerardo open pit mine in mid-June, following the supreme decree published by the Peruvian government

that allows medium-sized mines to restart operations.
The Atacocha site includes two mines: the Atacocha underground mine and the San Gerardo open pit mine. In light of the current macroeconomic environment and the uncertain time for recovery, the higher-cost Atacocha underground mine remains suspended, following the Company efforts to reduce costs and improve its operational
efficiency.
The Cerro Lindo and El Porvenir mines have continued to increase their throughput rates as planned, and the ramp-up phase is expected to be completed by the end of June. Cajamarquilla smelter also gradually improved its utilization rate and is running close to
full capacity.
Mining operations in Brazil and Três Marias smelter have been operating normally. As announced, Juiz de Fora smelter is running at 60% utilization rate and a gradual ramp-up to full production is expected in the third quarter. Construction activities at the Aripuanã project continue to progress.
In response to COVID-19 and following the best market practices, Nexa implemented international benchmark protocols in all its operations to safeguard the health of employees, third-party contractors and local communities.
In this unprecedented scenario, Nexa’s strategy remains focused on protecting employees and communities, ensuring business continuity and preserving cash generation. The 2020 guidance remains unchanged.
