Key Accountabilities

Resource Modelling & Estimation

• Lead and review geological and grade modelling for Mineral Resource estimates across BMNM assets.
• Ensure consistent application of estimation methodologies, domaining strategies, and validation practices.
• Provide technical oversight of consultant- and site-generated resource models.

Geostatistics & Uncertainty Analysis

• Apply advanced geostatistical techniques, including variography, kriging, and conditional simulation.
• Quantify uncertainty and risk associated with Mineral Resource estimates.
• Support decision-making by translating uncertainty into practical guidance for mine planning and project evaluation.

Support to Resource Classification & RPEE

• Work closely with RPEE, structural geology, and QA/QC principals to ensure resource models reflect realistic extraction scenarios.
• Support Mineral Resource classification through robust confidence and risk assessment.
• Contribute to sensitivity analysis and scenario testing for development studies.

Exploration & Resource Development Support

• Support exploration teams by defining drilling strategies that reduce uncertainty and improve model confidence.
• Assist with early-stage resource modelling for new discoveries and growth projects.
• Provide technical input into project evaluations, scoping studies, and long-term planning.

Governance & Standardization

• Define standards, workflows, and best practices for resource modelling and geostatistics across BMNM.
• Ensure all models are auditable, well-documented, and reproducible.
• Support internal reviews, audits, and technical governance processes.

Capability Building

• Mentor resource geologists and geostatisticians across the organization.
• Develop training material and internal guidance on geostatistics, simulation, and uncertainty analysis.
• Build sustainable in-house expertise and reduce long-term dependency on consultants.
