**News Release<br> June 9, 2026**

**Santacruz Silver Announces Publication of 2025 Sustainability Report for Mexican Operations**

**Vancouver, B.C. – Santacruz Silver Mining Ltd. (NASDAQ:SCZM) (TSX.V:SCZ)** ("**Santacruz**" or the "**Company**") is pleased to announce the release of the 2025 Sustainability Report (the "**Report**") for its wholly-owned Mexican subsidiary, Compañía Minera Zilar Mendi, S.A. de C.V. ("**Zilar Mendi**"), which operated as Carrizal Mining S.A. de C.V. ("**Carrizal Mining**") during the 2025 reporting period. The report highlights the Company´s environmental, social and governance ("**ESG**") performance and progress across its Mexican operations during 2025.

*"We are pleased to release our first sustainability report for our Mexican operations at Compañía Minera Zilar Mendi, which operated under the name Carrizal Mining during the 2025 reporting period. 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."*

 

This report has been prepared with reference to the 2021 Global Reporting Initiative (GRI) Standards. It covers the period from January 1, 2025, to December 31, 2025. The Report for Carrizal Mining is available on Santacruz's website at <u>www.santacruzsilver.com</u>.

 

**<u>Key 2025 Highlights</u>**

**ESG Approach:**

The Company's ESG approach is integrated into its corporate strategy and stakeholder engagement framework, guided by environmental, social and governance pillars that support responsible, ethical and sustainable operations. Rooted in the principle of meeting present needs without compromising the ability of future generations to meet their own, Carrizal Mining is advancing a cross-functional sustainability strategy and governance structure focused on managing ESG-related impacts, risks and opportunities.

**Environment**

Carrizal Mining's environmental priorities include preserving the natural environment and preventing pollution, reducing greenhouse gas emissions, optimizing water and energy use, managing waste through efficiency and recovery measures, and ensuring compliance with applicable environmental legislation and obligations. During the reporting period, the Company continued its water, air, soil and waste monitoring programs to support regulatory compliance and enhance environmental performance.

Carrizal Mining also maintained a measurement-based energy management approach focused on operational efficiency, continuous monitoring and the gradual adoption of more efficient technologies to reduce costs and environmental footprint while strengthening operational resilience. In 2025, the Company recorded electricity consumption of 696.31 kWh per tonne of concentrate produced, representing an increase of 2 kWh per tonne compared to 2024.

The Company further advanced its waste management and recovery initiatives during 2025. 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.

**Social**

Carrizal Mining recognizes occupational health and safety as a core priority given the nature of underground mining operations and the inherent risks associated with the industry.

During 2025, Carrizal Mining continued strengthening its health and safety management practices through the implementation of its Field Safety Leadership Activities (F.S.L.A.) framework, which promotes visible leadership, employee participation and early risk identification. The Company also continued advancing initiatives aimed to support employee well-being, critical incident management and continuous improvement across operations.

Safety management covers 780 employees. In 2025, the Company recorded 2,255,624 hours worked and 657 lost days related to occupational incidents, while maintaining zero workplace fatalities during the reporting period. Carrizal Mining also supported employee well-being through workplace health initiatives, providing 1,331 medical and psychological consultations as part of its employee health and wellness initiatives and reported zero cases involving violations of the rights of Indigenous Peoples.

**Governance**

Carrizal Mining's governance structure supports oversight of the Company's strategic, operational and sustainability objectives through dedicated management areas covering operations, risk management, technical services and controllership. Governance processes focus on regulatory compliance, operational oversight, financial integrity and risk management.

During 2025, the Company continued strengthening internal controls and executive accountability through annual performance evaluations linked to corporate objectives, ethics, environmental performance, occupational health and safety, and human rights policies. The Company also maintained policies and oversight processes related to ethics, human rights and regulatory compliance across its operations. Carrizal Mining further advanced its sustainability governance framework to enhance oversight of ESG-related impacts, risks and opportunities.

**<u>2026 ESG Priorities</u>**

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.

Carrizal Mining also plans to enhance ESG oversight through an expanded materiality and stakeholder engagement approach and the establishment of a Sustainability Committee in 2026 to support the effective management of ESG-related impacts, risks and opportunities.
