Position Summary
The Senior Mine Geologist serves as the primary technical authority for geological interpretation, grade control modeling, and ore characterization at a high-tonnage (~120,000 stpd) open-pit copper mine operating dual process circuits (sulfide concentrator and oxide LSXEW). Reporting to the Chief Geologist, this role bridges field geology execution and strategic resource management, providing direct technical oversight of mine geologists and technicians while owning key deliverables including block model updates, drill program execution, grade reconciliation analysis, and geometallurgical data integration. The Senior Mine Geologist ensures that geological outputs are accurate, timely, and actionable for mine planning and metallurgical optimization.
Duties and Responsibilities
Ore Control and Grade Control Modeling
  • Own the development and maintenance of a grade control model, integrating pit mapping, blast hole assays, on a rolling basis to support short-range and medium-range mine plans.
  • Generate and validate dig polygons and ore/waste boundaries for both sulfide mill feed and oxide leach material, ensuring correct routing based on copper grade, mineralization type, solubility characteristics, and deleterious element thresholds.
  • Define and maintain material type classifications with clear decision criteria aligned to metallurgical recovery expectations for both concentrator and LSXEW circuits.

Geological Interpretation and Field Work
  • Conduct and oversee detailed pit face mapping, geologic logging, and sampling programs with rigorous documentation of lithology, alteration , structure, and mineralization
  • Maintain and update the 3D geological model including lithological domains, structural interpretations, alteration zoning, and mineralization envelopes, ensuring the model reflects current pit conditions and new data inputs.
  • Interpret geological data in the context of deposit scale to improve predictive accuracy of grade and material type distributions.
  • Identify and communicate geological risk or opportunity stakeholders in advance of mining.

Grade Reconciliation and Data Analysis
  • Lead detailed grade reconciliation (F1-F3) comparing resource model predictions to grade control model outputs, plant head grades, and metallurgical recoveries across both concentrator and LSXEW circuits.
  • Identify root causes of reconciliation variances (geological, sampling, modeling, or operational) and develop corrective actions to improve predictive accuracy.
  • Maintain reconciliation databases and produce regular variance analysis reports for review by the Chief Geologist and site leadership.
  • Support resource estimation activities by providing validated geological interpretations, domain wireframes, and valid database.

Geometallurgical Integration
  • Collaborate with Metallurgy, Process Engineering, and LSXEW teams to characterize ore variability and its impact on plant performance, including hardness, flotation response, acid consumption, and copper solubility.
  • Support Mine to Mill initiatives by identifying and communicating rock mass characteristics that influence fragmentation, handling, and throughput to Drill and Blast and Processing teams.
  • Contribute to the development and maintenance of geometallurgical models linking geological attributes (mineralogy, alteration, oxidation) to processing outcomes.
  • Ensure ore routing decisions are supported by adequate characterization data including sequential copper analysis, mineralogical spot checks, and metallurgical test work results.
