Nexa follows structured processes for engagement and human rights due diligence, with a particular focus on managing relationships with Indigenous peoples in Brazil, as governed by internal procedure PG-GGS-GSBR-014-PT. This procedure establishes guidelines for identifying indigenous territories, conducting environmental licensing processes, and preparing specific studies, such as the Indigenous Component Study (ECI) and the Basic Environmental Plan for the Indigenous Component (PBACI), in addition to implementing and monitoring associated measures. All stages are grounded in International Labour Organization Convention No. 169, the principle of Free, Prior, and Informed Consent (FPIC), and international standards, such as those of the IFC. In 2024, the company conducted a comprehensive assessment of its human rights-related processes and is currently drafting its Human Rights Policy.

The due diligence approach is complemented by a set of policies, procedures, and corporate initiatives, including the Risk Management Policy and Manual, codes of conduct for employees and suppliers, a reporting channel (Ethics Hotline), community engagement procedures, and mechanisms for handling complaints. Nexa is also committed to international initiatives such as the Global Compact, the Sustainable Development Goals, the Business and LGBTI+ Rights Forum, and Women in Mining. Although it does not operate in conflict or high-risk areas, the company recognizes potential associated risks and takes preventive action by strengthening its governance, structuring its human rights policy, and implementing due diligence practices throughout its value chain, ensuring ethical, transparent operations aligned with international best practices.
