Senior Geomodeler
Position Summary The Senior Geomodeler develops and maintains geological and resource models that support exploration, mine planning, and production at a mining site. This role integrates geological, geostatistical, and operational data to produce accurate 3D orebody models and resource estimates that guide strategic and day-to-day mining decisions. The position works closely with geology, mine planning, and engineering teams to ensure models are reliable, up to date, and aligned with operational and reporting requirements.
Key Responsibilities
Build, update, and maintain 3D geological and resource models for mining operations and exploration projects. Interpret drillhole, geophysical, geochemical, and structural data to define mineralization domains and orebody geometry. Perform geostatistical analysis and resource estimation, including variography and classification of Mineral Resources. Ensure geological databases are accurate through QA/QC processes and data validation. Integrate geological models into mine planning, production scheduling, and reconciliation workflows. Support preparation of Mineral Resource and Reserve statements in accordance with NI 43-101, JORC, S-K 1300, or other applicable standards. Collaborate with mine geology and engineering teams to improve model accuracy and operational performance. Provide technical input to exploration targeting, resource expansion, and mine development studies. Mentor junior geologists and modeling staff and provide technical review of their work. Evaluate and implement improvements in modeling workflows, software, and methodologies.
Minimum Qualifications
Bachelor’s degree in Geology, Geological Engineering, Earth Sciences, Mining Engineering, or related field. 8+ years of experience in geological modeling, resource estimation, or mine geology in the mining industry. Strong understanding of geological interpretation, orebody modeling, and geostatistics (including variography and estimation methods). Experience with geological databases, QA/QC processes, and data validation. Proficiency in geological modeling software (e.g., Leapfrog, Vulcan, Datamine, MineSight, or similar). Experience working in multidisciplinary mining environments and communicating technical results to operational teams. Strong analytical, data interpretation, and technical reporting skills.
Preferred Qualifications
Advanced degree in Geology, Geostatistics, Mining Engineering, or related discipline. Professional designation (e.g., PG, P.Geo., or equivalent). Experience with mining reporting standards such as NI 43-101, JORC, or S-K 1300. Experience with resource reconciliation, grade control, and operational geology workflows. Familiarity with scripting or geostatistical tools (e.g., Python, R, Isatis, Supervisor). Demonstrated experience mentoring technical staff and leading modeling projects.
