Nexa Resources S.A.

Nexa Resources S.A. is an integrated zinc producer with mining and smelting operations in Peru and Brazil. It reports through two segments, Mining and Smelting.

- **Mining:** Five underground polymetallic mines produce zinc, copper, lead, silver and gold concentrates. They are Cerro Lindo, El Porvenir and Atacocha in Peru (the latter two form the Cerro Pasco Complex), and Vazante and Aripuanã in Brazil. Aripuanã's copper concentrate is sold under a five-year offtake agreement.
- **Smelting:** Three smelters (Cajamarquilla in Peru, Três Marias and Juiz de Fora in Brazil) process own and third-party concentrate into metallic zinc and zinc oxide. They also produce by-products such as sulfuric acid, silver concentrate and copper cement. In 3Q26, about half of the smelters' zinc concentrate came from Nexa's own mines.
- **Integration:** The integrated model lets Nexa capture value across the chain when treatment charges are low or negative. Nexa also uses three-year rolling average treatment charges in part of its third-party purchase contracts.
- **Projects:** The company holds an interest in Enercan, a hydroelectric associate that supports long-term energy supply. It is executing the Cerro Pasco Integration Project, whose tailings pumping system is targeted to start in 3Q27. It also explores brownfield targets around its mines.
- **Ownership:** Nexa is controlled by Votorantim S.A. (64.68%). In August 2026, Votorantim agreed to sell that stake to Boliden in exchange for Boliden shares, with closing expected in 1Q27. Updated Oct 29, 2026
