Hernan Kisluk's questions to Nexa Resources SA (NEXA) leadership • Q1 2025
Question
Hernán Kisluk inquired about the geotechnical issues at the Vazante mine and the lower-than-average production at Cerro Lindo, asking about the potential for recovery in the near term and any long-term operational consequences.
Answer
CEO Ignacio Rosado explained that the Vazante issue was an isolated stope collapse with high-grade ore, and the company is working to recover some of the lost production throughout the year. He noted that production at the Pasco complex (El Porvenir and Atacocha) is expected to fully recover from the heavy rainfall. However, Aripuanã's recovery is constrained by tailings filter performance until a new filter is installed in Q1 2026, placing it in the lower range of guidance. Overall, Nexa anticipates being in the mid-range of its annual production guidance.
