Position: Geologist 3 – Grade Control Evaluation

Objective of the Role

The successful candidate will ensure that reliable grade control models are generated and made available on time to support effective planning and design of mineable ore perimeters for open-pit operations and mineable stopes for underground operations.

The role will support achievable production budgets and reduce risks associated with delivering the annual gold production target in line with the Gold Mine Strategic Business Plan.

Key Responsibilities

The successful candidate will:

1. Promote compliance with site Health, Safety and Environment (HSE) policies, protocols and standards through participation in geology toolbox meetings and monitoring safety indicators, including Take5, workplace inspections, critical control verifications and safety observations.

2. Develop the technical skills and capabilities of the grade control modelling team by assigning tasks, monitoring work quality and progress, providing technical support and recommending relevant training.

3. Lead and guide the grade control team to ensure compliance with Standard Operating Procedures (SOPs) for open-pit and underground grade control modelling workflows, in accordance with AngloGold Ashanti protocols, standards and Quality Assurance and Quality Control (QAQC) requirements.

4. Establish standard working procedures for the grade control team and monitor compliance with modelling workflows and practices across open-pit and underground operations.

5. Review grade control models by validating laboratory and drillhole data, interpreting high-grade and low-grade wireframes, assessing metal domains and trends, and reviewing geostatistical estimation parameters.

6. Organise and conduct comprehensive internal peer-review meetings for each grade control model update before release.

7. Release grade control models within agreed timelines in line with the strategic mining sequence and communicate approved models effectively to relevant stakeholders.

8. Ensure Resource Planning Models and Integrated Planning Models are updated with the latest geological information in accordance with strategic mine design requirements.

9. Monitor and analyse grade control model performance against resource models, mine designs and actual mining results, establishing recovery and resource conversion factors to support material management and planning adjustments.

10. Evaluate mine designs to ensure that more than 90% of declared grade control resources are included in the mine design to optimise ore recovery.

11. Assess ore movement from designed perimeters or stopes to stockpiles and ROMPAD to evaluate model performance across the production value chain and support effective blending strategies.

12. Recommend adjustments to designed perimeters and stope designs to optimise ore recovery.

13. Provide geological risk and opportunity assessments covering material type, expected tonnes, grade and metallurgical recovery to planning engineers during open-pit weekly planning meetings and underground stope note meetings.

14. Inform the Evaluation Superintendent promptly about risks to production plans identified through model performance analysis and recommend appropriate mitigation measures.

15. Prepare weekly evaluation grade control meetings to communicate programme progress and status, and produce monthly mine-to-mill reconciliation reports based on grade control model performance.

16. Assign tasks to subordinates, monitor and review completed work, promote teamwork, coordinate handovers to Mine Planning and other stakeholders, support performance appraisals, identify training needs and communicate HSE and operational issues.

17. Maintain effective communication on grade control matters, promote best practices and continuous improvement, and stop, delay, instruct or escalate activities where KPI requirements are not met while recommending corrective actions.
