1. Purpose and Commitment

Oriental Copper is committed to ensuring that its business operations respect human rights and avoid contributing to conflict. We recognize our responsibility to source minerals—including Tin, Tantalum, Tungsten, and Gold (3TG), as well as extended minerals such as Copper and Silver—in a manner that does not finance or benefit armed groups in Conflict-Affected and High-Risk Areas.

2. Compliance Framework

Our due diligence program is designed to align with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals. We strive to meet the expectations of international regulations and industry standards, including:

• U.S. Dodd-Frank Act Section 1502
• EU Conflict Minerals Regulation (2017/821)
• LME & LBMA Responsible Sourcing Standards

3. Supplier Requirements

We expect our suppliers to establish their own due diligence programs and share our commitment to responsible sourcing. Suppliers are expected to:

• Reporting: Provide annual declarations using industry-standard templates, such as the CMRT and EMRT, upon request.
• Source Responsibly: Work towards sourcing materials from smelters and refiners validated as “”Conformant”” by recognized third-party audit programs   (e.g., RMAP, The Copper Mark, or LBMA Good Delivery List).”

• Traceability: Maintain sufficient records to support the origin of materials provided to Oriental Copper.

4. Risk Mitigation and Continuous Improvement

Oriental Copper follows a risk-based approach. In the event that a supplier is identified as high-risk, we will engage with the supplier to encourage improvement and corrective actions. We prioritize “Responsible Engagement” to support continuous improvement in the global supply chain.

5. Grievance Mechanism

We provide channels for stakeholders to report concerns regarding our supply chain. This policy is reviewed regularly by management to ensure its effectiveness and alignment with evolving global standards.

6. Transparency and Reporting

We are committed to transparency. Oriental Copper will provide necessary declarations to our customers to support their ESG and regulatory reporting needs.
