• Conduct independent reviews of Mineral Resource estimates prepared by site and regional teams.

• Evaluate geological interpretations, domaining strategies, estimation methodologies, variography, and classification approaches.

• Identify potential technical issues that could impact Resource confidence or estimation reliability.

• Assess geological models that underpin Resource estimates to ensure they appropriately capture lithological domains, structural controls, alteration patterns, and mineralization continuity.

• Identify opportunities to improve geological domaining and model interpretation.

• Evaluate grade estimation methodologies, search strategies, and interpolation approaches used in Resource estimation.

• Review the application of classification criteria and drill spacing assumptions used to support Resource confidence categories.

• Ensure Resource estimates align with corporate estimation standards and best practices.

• Identify geological and estimation risks that may impact Resource confidence, model robustness, or future Reserve conversion.

• Highlight areas where additional data, drilling, or improved modeling approaches could reduce uncertainty.
