Mine Geologist
Barrick Lumwana Mine
01.2018 - 02.2022
- Review previous Safety Inspection (PSI) statistics daily, identify hazards, and report them to ensure a safe work environment.
- Design ore blocks and maps, conduct routine dig face inspections, oversee ore spotting, and inspect material destinations (ROM stockpiles and dumps) to minimize ore dilution and loss.
- Supervise the Blast Movement Monitoring Systems (BMMT) during ore blast shots for better grade control by accurately marking ore blocks using blast movement vectors, which reduces ore processing costs and maximizes company profits.
- Schedule the crusher feed plan to achieve daily, weekly, monthly, and quarterly metal targets.
- Plan grade control and resource drilling, manage drilling rigs, and oversee both geology technicians and drilling crews.
- Log chip and core trays to define economic contacts (ore and waste zones) and delineate ore body extents for reserve models and pit design.
- Ensure QA/QC of collected samples, maintaining the required standards as per Standard Operating Procedures.
- Conduct mine-to-mill reconciliations daily, weekly, monthly, and quarterly, providing short-term interval controls (STIC) to meet planned targets.
- Ensure drilling compliance with mine plans, ensuring sufficient grade coverage before mining begins, thus increasing confidence in the predicted grades delivered to the process plant.
- Facilitate departmental meetings between Geology, Metallurgy, Mine Engineering, and Mine Operations to ensure smooth daily mine operations, providing checks and balances to achieve compliance.
- Track ore during mining, transportation, stockpiling, and processing, ensuring that dispatch records the correct ore blocks and that materials are directed to the correct stockpiles and waste dumps.
- Review ore blocks based on updated grade control models.
- Reduce operational costs by implementing efficient grade control strategies in collaboration with the production team.
- Increase the accuracy of ore reserve estimations by developing and updating geological models using advanced software tools.
- Safeguard data quality by maintaining proper calibration of analytical equipment for consistent results.
- Streamline database management by organizing critical geological information for easy access by project stakeholders.
