This report represents an important milestone in our broader commitment to advancing sustainability practices across the entire company. At Carrizal Mining, 2025 was more than a period of expansion; it was a year devoted to a comprehensive assessment of our processes, a critical review of our operating model, and the design of a new strategy that will enable us to move more decisively toward a more sustainable operation,” commented Arturo Préstamo, Executive Chairman and CEO of Santacruz. “Our approach focuses on strengthening safety, environmental performance, operational efficiency, governance, and social dialogue, while advancing innovation and responsible resource management. The result is a renewed corporate strategy with clear objectives to enhance our ability to generate sustainable value and respond responsibly to stakeholder expectations.”

During the reporting period, the Company continued its water, air, soil and waste monitoring programs to support regulatory compliance and enhance environmental performance.

Non-mineral hazardous waste generation declined by 27.62% compared to 2024 as a result of stricter process controls and waste minimization programs, while flotation tailings increased by 1.17% in line with higher production levels and were managed through enhanced handling and storage practices.
Carrizal Mining also expanded its recycling and recovery efforts through internal awareness campaigns, dedicated collection programs and partnerships with authorized waste management providers to support environmentally responsible disposal and recycling practices.

Carrizal Mining further advanced its sustainability governance framework to enhance oversight of ESG-related impacts, risks and opportunities.
2026 ESG Priorities
Looking ahead, the Company’s priorities in 2026 include strengthening its preventive culture, progressively incorporating technological innovation and advancing ESG performance to support a modern, competitive and socially responsible mining operation that generates sustainable value for stakeholders.
