çThe position implements Sibelco Geology & Mining standards locally, develops team capability, and ensures that technical outputs are reviewed, approved and communicated through clearly defined governance, including the Competent Person and the Sibelco Resources & Reserves Steering Committee where applicable.

Responsibilities

• Coordinate geological investigations that improve knowledge of operating deposits and identify, quantify and qualify additional mineral resources and reserves.
• Own local geological data governance, databases, QA/QC and data integrity. Ensure assumptions, modifying factors, risks, uncertainties and decisions are documented.
• Coordinate resource and reserve updates and annual reporting. Ensure models and estimates are independently reviewed and submitted to the Competent Person and the Sibelco Resources & Reserves Steering Committee for validation or approval, as applicable.
• Monitor reserve life, geological-model risk and corrective actions. Support reserve replacement and exploration opportunities aligned with business needs.
• Provide geological inputs to mine planning and reserve optimization. Coordinate with Mine Engineering on reserve conversion, economic assumptions, stripping, waste and tailings management, and geotechnical and hydrogeological risks.
• Establish reconciliation from geological model to mine plan, production and final products. Track deviations, causes and corrective actions, including Mine-to-Plan performance.
• Lead the local geology team, define priorities and clarify who prepares, reviews, approves, is consulted and is informed for key technical deliverables.
• Ensure work is assigned according to competence. Review quality and delivery, coach team members and maintain succession and development plans.
• Implement Sibelco Core Geology Handbooks and Geology & Mining Guidelines locally. Identify capability gaps and coordinate training in field geology, QA/QC, modelling, resource and reserve reporting, reconciliation and relevant software.
• Build effective interfaces with Operations, Mine Engineering, Quality, Environment, Finance and business leadership.
• Ensure fit-for-purpose geological interpretation, domaining, estimation, classification, validation and documentation.
• Review modelling assumptions and outputs, coordinate peer review and audits, and close agreed actions.
• Ensure models support medium- and long-term mine planning, selective mining, product-quality forecasting and reconciliation.
• Maintain consistent modelling workflows and appropriate use of approved software and data systems.
• Provide geological leadership for operating-site studies, resource extension, new deposits, acquisitions, due diligence and other business-development projects.
• Maintain oversight of mineral titles and coordinate responses to commitments or requirements from competent authorities, with Legal, Environment and permitting specialists.
• Monitor relevant mineral legislation and ensure geology deliverables support continued compliance.
• Define scopes, schedules, budgets, risks, decision points and technical acceptance criteria for geology work packages.
• Provide geological information required for new projects and investment decisions.
• Implement and continuously improve local geology processes in line with Sibelco standards and lessons learned.
• Participate in operational improvement initiatives, including WCM and 5S where applicable.
• Ensure compliance with Quality, Environment, Health and Safety management-system procedures. Maintain safe, organized field, core-storage and office work areas.
