Company Overview

Nexa Resources S.A. is a publicly listed mining company focused on the production of base metals, primarily zinc and copper, with additional by-products including lead, silver, and gold. The company operates within the metals and mining industry, serving global industrial customers in sectors such as construction, infrastructure, manufacturing, and electronics. Its core revenue is driven by the extraction, processing, and commercialization of zinc and copper concentrates and refined metal products.

The company has a vertically integrated operating model that includes mining, beneficiation, smelting, and refining, providing cost control and supply chain resilience. Nexa is majority-owned by Votorantim S.A., a large Brazilian industrial conglomerate, which provides strategic backing and operational expertise. Nexa traces its origins to mining assets developed by Votorantim in the mid-20th century and was formally established as a standalone company prior to its initial public offering. It has since evolved into one of the largest zinc producers in the Americas with a diversified asset base across South America.

Business Operations

Nexa generates revenue through its Mining Segment and Metallurgical Segment, which together encompass exploration, extraction, processing, smelting, and refining activities. The mining operations produce zinc, copper, and polymetallic concentrates, while the metallurgical operations refine these materials into zinc metal and alloys sold to industrial customers. Revenue is influenced by global commodity prices, production volumes, and treatment and refining charges.

The company operates multiple underground and open-pit mines, as well as smelting and refining facilities, primarily in South America. Its key controlled assets include integrated mining and metallurgical complexes and long-life mineral reserves. Nexa operates through wholly owned subsidiaries and controlled entities, with no material joint ventures publicly disclosed as core revenue drivers. Domestic operations in Brazil and Peru are complemented by international sales to customers in North America, Europe, and Asia.

Strategic Position & Investments

Nexa’s strategy focuses on disciplined capital allocation, operational efficiency, and extending mine life through exploration and brownfield expansion. Growth initiatives emphasize improving productivity at existing assets, advancing exploration projects, and selectively investing in projects that enhance zinc and copper output while maintaining cost competitiveness.

The company has historically invested in mine expansions, tailings management improvements, and metallurgical upgrades to enhance recovery rates and environmental performance. Its asset portfolio includes several wholly owned operating subsidiaries managing individual mines and smelters. Nexa is also exposed to emerging mining technologies related to automation, digital mine planning, and environmental controls, particularly in water management and tailings safety, reflecting increased regulatory and sustainability requirements in its core jurisdictions.

Geographic Footprint

Nexa’s headquarters are located in Luxembourg, while its principal operations are concentrated in South America, particularly Brazil and Peru. These countries host the majority of the company’s producing mines, smelters, and development projects, making them central to Nexa’s revenue and reserve base.

Beyond its core operating regions, Nexa maintains commercial and trading activities that support sales into North America, Europe, and Asia, giving the company a global market presence despite a geographically concentrated asset base. Its international influence is primarily operational and commercial rather than ownership-based, with investments focused on mining-friendly jurisdictions in Latin America.
