Title:\u00a0Senior Mine Geologist Opportunities (3 positions) \u2013 Sotta Mining Corporation Limited \u2013 December 2025
\nSenior Mine Geologist (3 positions)\u00a0Reports to:\u00a0Mine Geology Superintendent
\nThe Senior Mine Geologist is directly accountable for leading all daily GC activities in the open pit and for delivering robust geological inputs in line with the MMP. The role leads GC block modelling and wireframing, plans and supervises RC grade control drilling, and manages GC sampling and logging to ensure precise ore\u2013waste delineation and strict control of dilution and ore loss.
\nThe Senior Mine Geologist safeguards the accuracy and integrity of all geological data through validation and effective database management, ensuring that operational decisions are based on reliable, up-to-date information. The role is also responsible for operational EOM reporting and mine-to-mill reconciliation, and has clear accountability for defining and applying NAF\/PAF criteria, and for ensuring material is routed correctly to waste rock dumps (WRDs), NAF\/PAF destinations with operational and environmental requirements.
\nRoles and Responsibilities:<\/p>\n
Identify geology-related hazards at pit faces and drill patterns (access, bench edges, interaction with equipment, heat, dust, visibility) and intervene or stop work where conditions are unsafe.
\nSupervise and mentor Mine Geologists, Junior Geologists and Grade Control Technicians to build capability in GC drilling supervision, sampling, logging, GC wireframing, GC block modelling, database management and reconciliation.
\nProvide on-the-job training and coaching to develop national staff, supporting structured competency development and succession planning.
\nPlan and supervise RC GC drilling programs to achieve appropriate data density for ore\u2013waste delineation in line with the MMP.
\nLead QA\/QC for GC sampling (standards, blanks, duplicates, repeats) and investigate and close out any QA\/QC issues.
\nMaintain and update GC mineralisation wireframes using current drilling, mapping and logging data.
\nBuild and update short-range GC block models to support ore mark-up, short-term planning and dilution control.
\nIssue clear, accurate ore polygons and dig plans to Mining and Survey to minimise ore loss and dilution and meet grade targets.
\nEnsure all GC drilling, sampling, logging and assay data are captured, validated and loaded into the geological database in a timely manner.
\nMaintain a clean, auditable GC database (including NAF\/PAF coding) with robust data validation and QA\/QC checks.
\nLead operational reconciliation: GC model vs mined (survey) and mined ore vs plant feed in collaboration with Metallurgy and Mining.
\nPrepare monthly reconciliation summaries, including tonnage, grade, dilution and ore loss, and explain key variances and trends.<\/p>\n
Qualifications and Licences \/ Experience \/ Skills:<\/p>\n
Bachelor\u2019s degree in Geology, Geological Engineering or equivalent.
\nOver 7 years experience in open-pit mine geology and grade control for gold or base metal.
\nDemonstrated capability in wireframing and block modelling for operational decision-making and dilution control.
\nProficiency with Micromine for wireframing, modelling and grade control; experience with AcQuire for data management and QA\/QC in greenfield to operational ramp-up projects.<\/p>\n
