Technical Expert Geology Modeler

Technical Expert - Geology Modeler

Location:

Columbus MT

Schedule:

hour workdays

The Geologic Modeler plays a key technical and leadership role in developing and maintaining highquality 3D geological models that support resource definition mine planning and operational decisionmaking in an underground narrowvein environment. This position ensures that geological interpretations-driven by facescale observations mapping and diamonddrill data-provide accurate guidance for grade control ore/waste discrimination and long and shortrange planning.

Working closely with geology engineering and data collection teams the Geologic Modeler champions bestpractice methods for modeling structurally complex narrow vein systems and continuously enhances the organizations understanding of orebody geometry continuity and grade distribution.

Job Responsibilities and Duties:

• Contribute to process improvement for grade control reconciliation and geological knowledge transfer.
• Promote and model a strong safety culture in all underground and officebased activities.
• Follow all health safety and environmental policies while proactively identifying operational hazards.
• Deliver timely updates to grade control models by incorporating:
• Daily underground face maps and geological observations
• Channel/face sampling data
• Underground diamonddrill core results
• Develop and maintain modeling standards tailored to narrowvein structurally controlled deposits.
• Apply and refine bestpractice methods for domaining vein interpretation structural modeling and grade interpolation.
• Provide clear accurate geological models that support:
• Shortterm mine planning
• Ore/waste discrimination
• Maximizing ore recovery and minimizing dilution and deletion
• Work closely with mine geologists and engineers to reconcile planned vs. actual development and production outcomes.
• Integrate drilling mapping and production reconciliation results to progressively improve model performance.
• Collaborate with mine geology resource geology and engineering teams to prioritize modeling tasks according to operational needs.
• Offer training and mentorship in modeling workflows vein interpretation and domaining methodologies.
• Communicate modeling progress risks and opportunities to technical leaders and operational stakeholders.
• Support the resource/reserve team with longrange modeling data QA/QC and geological risk identification.
• Drive innovation in modeling techniques specific to narrowvein systems including structural controls vein continuity assessment and grade variability.

Qualifications and Skills:

• Strong proficiency with geological modeling software (e.g. Leapfrog Geo Vulcan preferred).
• Demonstrated experience interpreting structurally complex vein systems using underground mapping and diamonddrill data.
• Effective collaborator with strong communication skills across multidisciplinary technical teams.
• Adaptable forward thinking and comfortable working in fast-paced underground operational settings.

Education & Experience

• Bachelors degree in Geology Earth Science Geological Engineering or a related field.
• Minimum five years of experience in underground production geology narrowvein operations grade control or exploration (preferred).
