Senior Mine Resource Geologist

Position Summary

The Senior Mine Resource Geologist is responsible for all aspects of mineral resource estimation, geological modeling, database integrity, QA/QC program management, and resource reporting in support of exploration, project evaluation, feasibility study advancement, and mine planning activities at the mine.

Working closely with exploration, engineering, and technical services teams, this role provides primary technical leadership in resource geology, directs the work of independent Qualified Person (QP) consultants, ensures compliance with NI 43-101 and applicable reporting standards, and applies rigorous geological and geostatistical methods to develop reliable, auditable resource models that support strategic and investment-grade decision making.

This position plays a central role in advancing the project through prefeasibility and feasibility stages and will mentor junior and site geological staff as the team grows.

Primary Responsibilities

• Develop, maintain, and update 3D geological domain models and resource block models using Leapfrog Geo and geostatistical estimation platforms, ensuring models are current, auditable, and suitable for feasibility-level decision making.
• Direct the technical scope and review deliverables of independent Qualified Person consultants for mineral resource estimations prepared in accordance with NI 43-101 and, where applicable, SEC S-K 1300 reporting standards.
• Interpret geological, geochemical, and geophysical data to support resource classification and mine planning.
• Integrate geometallurgical domains into resource models to support process design, recovery forecasting, and mine planning for both sulfide flotation and leach-amenable material.
• Contribute resource model inputs to prefeasibility and feasibility study work, including resource classification confidence upgrades through targeted infill and condemnation drilling.
• Conduct data validation, direct QA/QC procedures, ensure database integrity, and perform timely model reconciliation.
• Collaborate with mine planning engineers to optimize mine designs and production schedules.
• Develop and implement resource reconciliation programs to track model performance against actual production and grade control data as the project advances toward operations.
• Provide technical guidance and mentorship to mine geologists and technicians.
• Prepare technical reports, documentation, and presentations for internal and external stakeholders.
• Manage resource classification methodology, including variogram modeling, estimation validation, and confidence category assignments consistent with NI 43-101 category definitions.
• Develop resource models in support of corporate mergers and acquisitions (M&A), due diligence studies, and other corporate business development efforts.

Qualifications

• Bachelor's degree in Geology, Geological Engineering, or a related field.
• Minimum of eight (8) years of experience in mining geology with a strong focus on resource estimation.
• Professional designation (P.Geo., SME-RM, CPG, or equivalent) or eligibility required.
• Proficiency with Leapfrog Geo for 3D geological and resource modeling.
• Demonstrated competency with at least one geostatistical estimation platform for variography, estimation, and model validation.
• Strong understanding of geostatistics and mineral resource estimation techniques.
• Direct experience with porphyry copper deposits, including an understanding of deposit-scale geological controls, alteration zoning, domain definition, and grade continuity.
• Experience with both open pit and underground mining methods.
• Demonstrated experience designing, managing, and interpreting resource definition and infill drilling programs, including drill targeting, collar surveying, logging standards, and integration of results into updated resource models.
• Proficiency with acQuire or equivalent geological database management systems, including QA/QC protocol design, data validation workflows, and compliance with corporate database standards.
• Experience contributing resource model inputs to Preliminary Economic Assessments (PEA), Prefeasibility Studies (PFS), or Feasibility Study technical reports.
• Strong leadership skills with a desire to mentor and develop site staff.
• Ability to work independently while contributing to a collaborative, progressive, and high-performing team.
• Must be legally authorized to work in the United States.
