Lead Geologist, Geometallurgy

Geometallurgical Modeling / Ore Characterization

• Develop, maintain, and continuously improve the geometallurgical framework linking ore types to processing behavior (grindability, sulphur, recovery, reagent consumption).
• Build and maintain geometallurgical datasets supporting short-, medium-, and long-term planning.
• Provide predictive insights on ore behavior to support mine planning, blending, and processing strategies..

Blending / Processing Support

• Work closely with mining and processing teams to define optimal ore blends, considering sulphur content, gold grade, hardness, and metallurgical response.
• Support POX feed stability through proactive ore type management and forward-looking metallurgical predictions.
• Translate geological variability into practical, operational guidance for daily and weekly production planning.

Testwork / Laboratory Oversight

• Define and oversee metallurgical testwork programs (grindability, leach tests, GRG, reagent optimization).
• Ensure QA/QC protocols are applied consistently across all metallurgical testwork and laboratory activities.
• Supervise laboratory workflows, equipment calibration, and data validation..

Operational Performance / Continuous Improvement

• Analyze plant performance data against ore characteristics and blends to identify improvement opportunities.
• Support continuous improvement initiatives aimed at increasing recovery, reducing reagent consumption, and improving plant stability.
• Contribute geometallurgical input to technical reports, forecasts, and management dashboards..

Cross-Functional Integration

• Act as the technical interface between Geology, Mining, Processing, and MRM functions.
• Participate in regular operational meetings to communicate expected ore behavior and associated risks.
• Provide geometallurgical input into technical studies, life-of-mine planning, and future ore source evaluations.
