This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Nexa Resources S.A. is a global mining and metallurgy company whose core business is the extraction and processing of non-fuel minerals. It operates polymetallic mines and zinc smelters in Brazil and Peru, with over 60 years of experience in the sector. The company derives its revenue from the production of zinc, copper, lead, silver, and gold. This business model, centered on large-scale mineral extraction, places it squarely within the extractive industries.
The company has been referenced in reports and news articles concerning allegations of abuse and attacks against human rights defenders, though specific details of these incidents are not provided in the gathered evidence. Nexa maintains a public compliance program and emphasizes ethics and transparency in its communications.
Nexa Resources SA operates zinc, lead, and copper mining and smelting facilities in Brazil and Peru. In April 2024, the Business & Human Rights Resource Centre documented that rock blasting at a Nexa Resources operation in Peru damaged local water infrastructure, directly impacting community water access. The company did not respond to requests for comment on the incident.
The company’s operations are linked to broader environmental risks inherent to extractive activities in ecologically sensitive regions. A technical report for its Aripuanã Zinc Project in Brazil notes the need to address environmental violations and implement mitigation measures, indicating ongoing regulatory and remediation concerns. While specific penalty totals are not detailed in the provided evidence, the pattern of incidents involving infrastructure damage and the acknowledged need for corrective action place the company within the scope of documented environmental harm from mining operations.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
