Message from Our Executive President

‌Message from Our Executive President

(GRI 2-22)

Dear Stakeholders,

At Grupo Minero Sinchi Wayra, we are proud to present our 2024 Sustainability Report, which outlines our social, environmental, and economic performance in alignment with the requirements and standards of the new Global Reporting Initiative (GRI) structure, in accordance with the GRI Standards. This report adopts an integrated approach supported by the International Financial Reporting Standards (IFRS) S1, and includes specific sectoral guidelines for mining, in response to the expectations of our investors.

It demonstrates our commitment to a sustainable future and to transparent communication of our actions. Our goal is to become a benchmark for sustainable mining in Bolivia, which means leading initiatives that generate positive impacts while responsibly managing both actual and potential negative impacts on society (employees, communities, and civil society), the economy, and the natural environment.

We continue to integrate sustainability not only into our corporate strategy, but also into our daily operations and risk management practices. Thanks to this perspective, we have reinforced the economic value we allocate to our stakeholders, particularly through collaboration with local communities under current agreements. This year, we invested over two million dollars in projects that support their development.

We also continue advancing sustainability by actively participating in the United Nations Global Compact Bolivia Network, where we have stood out as leaders of the Transformational Governance Working Group. This has allowed us to create spaces for knowledge-sharing with other industries and foster synergies aimed at achieving 13 prioritized Sustainable Development Goals (SDGs), 21 targets, and 21 indicators-identified through our materiality process-to demonstrate progress with impact toward the 2030 Agenda.

In this context, this edition of our report outlines updates to our materiality analysis, prepared in accordance with the GRI Standards, incorporating double materiality and Environmental, Social, and Governance (ESG) criteria. This approach enables us to provide investors with a broader strategic and financial perspective, along with an understanding of potential negative impacts stemming from climate change that may affect the value of our business and our fiduciary duty to pursue responsible investment.

To this end, we identify, assess, and prioritize the most relevant ESG criteria and align them with our corporate and financial risks. This approach helps us allocate resources more effectively, maximizing our positive environmental, social, and governance impacts. In 2025, we will continue to review and strengthen our commitments to impact materiality and double materiality, responding effectively to evolving external demands and stakeholder

Message from Our Executive President

expectations, while aligning with the capital-based approach already defined for governance, strategy, management, and related metrics for continuous improvement.

This year, we updated our corporate mission, vision, and values, reaffirming that life, safety, and health are fundamental priorities for our personnel. As such, we maintain a proactive management approach that includes implementing controls and measures to eliminate or reduce risks in the workplace. We are equally committed to sustainability, the environment, and innovation, addressing corporate risks related to human rights with due diligence and evaluating their implications on people in specific areas.

I would like to extend my sincere gratitude to each of our 1,365 workers for their dedication and contributions to the mission of our mining group.

With great enthusiasm, I invite you to read our 2024 Integrated Sustainability Report. We hope our progress serves as a source of inspiration on the path toward responsible and pioneering mining in Bolivia.

Thank you very much!

Eduardo Torrecillas Executive President
