How Does Nexa Company Work?

How is Nexa shaping the global zinc supply?

Nexa Resources is a leading base-metals producer whose 2025 ramp-up at Aripuanã helped push annual zinc output above 335,000 tonnes, reinforcing its role in energy-transition supply chains and boosting 2025 revenue to about $2.65 billion.

As a vertically integrated operator with five underground mines and three smelters in Brazil and Peru, Nexa converts polymetallic ores into high-purity metals while leveraging low-cost energy and high-grade assets to sustain margins.

How does Nexa Company work? Briefly: through integrated mining-to-smelting operations, scale from Aripuanã, and strategic positioning in zinc markets — see Nexa Porter's Five Forces Analysis

Nexa operates an integrated mining-to-smelting model focused on underground polymetallic mines and in-house processing, capturing value across extraction, concentrate production and refined metal output while supplying alloy and high-grade zinc products to industrial customers.

Core mining footprint

Five underground polymetallic mines—Cerro Lindo, El Porvenir and Atacocha in Peru; Vazante and Aripuanã in Brazil—produce concentrates rich in zinc, lead and copper with precious metal credits.

Vertical integration

By 2025 internal processing reached approximately 62 percent, reducing exposure to third-party treatment and refining charges and allowing margin capture across the value chain.

Smelting and processing

Three smelters—Cajamarquilla (Peru), Juiz de Fora and Três Marias (Brazil)—process a large share of Nexa Company operations' concentrates into refined metals and specialized alloys for customers.

Logistics and market access

Strategic port access in Callao and multiple Brazilian outlets enables distribution across the Americas and Europe, mitigating common logistical bottlenecks for customers in automotive, construction and infrastructure.

Operational advantages combine technology, energy and mining methods to strengthen the Nexa business model and How Nexa works across regions.

Competitive differentiators

Nexa Company structure leverages renewable energy, automation and targeted downstream capacity to reduce costs and improve margins.

• Brazilian smelters benefit from low-cost hydropower, lowering smelting energy expense versus global averages.
• Peruvian sites use high-capacity underground mining and automated sorting to increase ore recovery and grade control.
• Internal processing capture of ~62% in 2025 reduces sensitivity to external treatment and refining charges.
• Distribution network supports tailored alloys and high-grade zinc supply to diversified industrial clients.

Nexa’s revenue mix in 2025 is led by zinc sales, which represented approximately 67 percent of consolidated revenue, supplemented by copper, lead, silver and gold; monetization combines long‑term contracts, LME‑indexed pricing and premium pricing for value‑added alloys and by‑products.

Primary revenue driver

Zinc sales via Mining and Smelting accounted for the bulk of revenue, with the Smelting segment selling over 595,000 tonnes of metal annually, including galvanizing grades.

Multi‑metal exposure

Copper contributed about 13 percent, lead 7 percent, and silver/gold the remaining 13 percent, providing a natural hedge across commodity cycles.

Pricing mechanisms

Sales mix blends long‑term supply contracts and spot market transactions, with pricing typically indexed to the London Metal Exchange to align Nexa Company operations with market benchmarks.

Value‑added products

Premium alloys such as Zamak and die‑casting grades follow a tiered pricing strategy, commanding higher margins than standard zinc ingots under the Nexa business model.

By‑product monetization

In 2025 Nexa expanded sales of sulfuric acid from smelting operations to fertilizer and chemical buyers in South America, diversifying revenue streams.

Regional sales strategy

Revenue is balanced between domestic Brazilian sales—where Nexa holds a dominant market share—and exports, enabling optimization for demand spikes and currency benefits.

Nexa Company monetization relies on a mixed sales strategy and product segmentation that supports margins and cash flow while hedging commodity exposure; further detail available in Revenue Streams & Business Model of Nexa.

Monetization levers and facts

Key levers within the Nexa Company structure include contract mix, product premiuming, by‑product sales and geographic optimization—each tracked against commodity prices and production volumes.

• Smelting volume: over 595,000 tonnes zinc metal sold annually.
• Zinc share of revenue: approximately 67 percent in 2025.
• Copper, lead, silver/gold split: 13 percent, 7 percent, and 13 percent respectively.
• Sulfuric acid sales added in 2025 to fertilizer and chemical markets in South America.

Nexa’s key milestones include the full-scale ramp-up of the Aripuanã mine to 100 percent operational efficiency in early 2025, a capital deployment exceeding $600,000,000, and the strategic pivot from a pure mining firm to an integrated producer that proved resilient during the 2025 European energy crisis.

Operational scale-up

The Aripuanã ramp-up added significant copper and lead capacity, enhancing Nexa Company operations and improving throughput across its portfolio.

Integrated producer strategy

Transitioning to an integrated producer insulated margins when high energy costs in Europe forced non-integrated smelters to curtail production.

Low‑cost smelting footprint

Brazilian smelters benefit from long-term energy contracts and self-generation, forming a competitive edge in Nexa’s business model and Nexa company structure.

Technological leadership

Investment in the Nexa Way program uses data analytics to optimize mine scheduling and energy consumption, improving unit costs and operational reliability.

Nexa’s strategic moves also include strengthened community engagement and desalination investments in Peru to address regulatory challenges and preserve the social license to operate while extracting five metals from single ore bodies to capture economies of scope.

Competitive edge and outcomes

Core functions of Nexa Company combine asset diversification, low-cost energy, and analytics-driven operations to sustain margins and volume through commodity cycles.

• Aripuanã’s ramp-up raised concentrated metal output materially in 2025, supporting revenue growth.
• Long-term energy contracts and on-site generation reduce exposure to global power price spikes.
• The Nexa Way delivered measurable efficiency gains in scheduling and energy use across mines and smelters.
• Five-metal extraction increases resilience to single-commodity price declines and improves overall profitability.
