Sustainability | Hochschild Mining

“We take enormous pride in managing our business in a way that ensures returns to all stakeholders, including our employees and the communities surrounding our operations.”

Eduardo Hochschild, Board Chair

APPROACH AND STRATEGY

Our long-term business model is guided by our Corporate Sustainability Policy, offering an attractive investment opportunity for our shareholders through the creation of long-term value from safe, innovative, and environmentally-sound operations.

Hochschild’s sustainability reporting ecosystem

We are committed to providing our stakeholders with an ongoing and transparent account of our material topics and continuous ESG progress. As such, we publish reports on our sustainability performance through continuous updates of our website, quarterly updates on our ESG KPI’s, and a standalone Sustainability Report every two years. In years in which we do not publish this report, we include a detailed sustainability section in our Annual Report. Our last standalone report was published in 2024, which was prepared with reference to the Global Reporting Initiative (GRI) Mining Sector Standards and was independently assured by EY.

Culture and Communication

FLICMA

In 2025, we held the third edition of the Festival of Literature, Culture and Art of Mara Rosa and Amaralina (FLICMA), with nearly 3,400 participants, including students, teachers, and local leaders. The 3-day event included workshops, artistic performances, storytelling sessions, book raffles, educational panels, theatre competitions, and a talent show. With the involvement of ten local schools and three educational centres, FLICMA has become a key initiative for fostering reading, cultural appreciation, and stronger community connections.

Environmental Ambassadors Programme

To fully embed our environmental culture into our everyday operations, we invite employees and contractors alike across all levels to be part of our Environmental Ambassador programme. The programme’s main objective is to train agents of change who strengthen the culture of environmental awareness within the Company. Since the programme’s inception in 2021, we have introduced 118 Environmental Ambassadors across all sites.

HOCHSCHILD SAFETY 2.0

Seguscore

Launched in 2022, the SeguScore is an in-house safety performance indicator that measures both proactive and reactive safety metrics. It includes leading indicators like leadership presence, behavioural observations, and mini audits, as well as lagging indicators such as injury frequency and severity rates and the occurence of high potential events. This tool provides team leaders with valuable information, which allows them to review safety conditions in their areas, improve accident/incident investigations, increase communication, and make necessary improvements to avoid the occurrence of safety events.

Our People

Preventing workplace harassment

Since 2020, we have partnered with Harassment-Free Workplaces (“Espacios Laborales sin Acoso” - ELSA), an organisastion specialising in the prevention of workplace sexual harassment, to carry out an annual comprehensive diagnosis at our operations and administrative offices in Peru. The results from our last survey, conducted in 2025, showed reductions in the number of sexual harassment cases, increased awareness of company policies and reporting channels, and a more positive perception of company tolerance and case management. We plan to launch the campaign in Brazil and Argentina in 2026.

Stakeholder Engagement

Materiality assessment

We undertake a sustainability materiality assessment update every two years in order to identify and report on ESG topics where we may have social or environmental impact, and which may create financial risks or opportunities for our business.

Our last materiality assessment, performed in 2024, highlighted six topics as being of very high priority: local communities and socio-economic development; water management; climate change resilience; occupational health and safety; biodiversity and ecosystem services; and management of waste and tailings.

Engagement processes

The aim behind our long-term business strategy is to provide an attractive investment proposition for our shareholders whilst also adding value for our customers, employees, suppliers, and local communities. To ensure that both objectives are met, we focus our efforts on the areas where we can have the biggest impact, supported by our commitment to the United Nations Sustainable Development Goals (UN SDGs).
