On July 31, Nexa announced that Phase I of its Cerro Pasco integration project has reached key milestones, including the completion of engineering design and receipt of all necessary permits. Phase II is advancing on schedule. The project is expected to extend the mine life of Atacocha and El Porvenir by over a decade while enhancing overall profitability. At the Aripuanã mine, the procurement and installation of the fourth tailings filter remain on track for completion in the second half of 2025, with commissioning anticipated in the first half of 2026—unlocking full production capacity.
Zinc in concentrate production in Q2 2025 reached 74kt, up 9% QoQ, primarily driven by improved operational performance at Nexa’s Peruvian mines. Compared to Q2 2024, production was down 12% due to lower output from Brazilian operations, partially offset by higher contributions from Atacocha and El Porvenir.
In Q2, refined zinc and zinc oxide sales totaled 145kt, up 12% from Q1, supported by higher production at Cajamarquilla and Juiz de Fora, along with increased zinc oxide output at Tres Marias. Total production of refined zinc and zinc oxide reached 139kt, up 5% QoQ and down 9% YoY, in line with Nexa’s full-year sales guidance of 560kt to 590kt.
Nexa signs third-party concentrate purchase contracts with 3-year moving average TC. Approximately 30% of 2025's purchased volumes are exposed to 2025 TC, with most contracts signed before April. Similar level's expected in 2026.
