South America: Nexa Resources strengthens zinc leadership with 14% q-o-q surge in output in Q3CY’25

  • Gross profit reaches $154 million, up 21% y-o-y
  • Group zinc concentrate production touches 84,000 t

Nexa Resources reported a strong third quarter 2025, reinforcing its position as a leading global zinc producer. The company recorded a net income of $100 million, supported by higher zinc production, stronger by-product prices, and continued cost discipline. Adjusted EBITDA rose 16% q-o-q to $186 million, reflecting operational gains across its mining and smelting segments.

Operationally, zinc production reached 84,000 t, led by record performance at Aripuanã and recovery at Vazante. Mining cash cost improved sharply to $0.49/lb from $0.11/lb, a 345% improvement, supported by higher by-product credits and lower treatment charges. Meanwhile, smelting cash cost rose 7% q-o-q to $1.32/lb, reflecting higher raw material prices.

Financially, the adjusted EBITDA margin stood at 24.4%, up 1.7 percentage points (pp) from Q2 but 1.4 pp lower y-o-y, mainly due to higher input costs in the smelting segment. The mining segment’s EBITDA rose 28% y-o-y to $164 million, while the smelting segment declined 59% y-o-y to $23 million.

Nexa reaffirmed its 2025 zinc production guidance of 300,000 to 336,000 t and zinc metal and oxide sales of 560,000 to 590,000 t, with capital expenditure of $90 million focused on sustaining operations and the Cerro Pasco Integration Project, on track for commissioning in 1H 2026. The company’s Cajamarquilla smelter, fully powered by renewable hydro energy, and its circular economy initiatives — including 100,000 eco-bricks produced from smelter residue — highlight its commitment to sustainability as global zinc fundamentals continue to strengthen.
