Job Description

G Mining Ventures is seeking an Analytical Laboratory Manager to join the Process/Metallurgy team at the Oko West Project in Guyana. The successful candidate will be responsible for ensuring the safe, accurate, and timely preparation, analysis, validation, and reporting of mine, exploration, process, metallurgical, and environmental samples, while ensuring that analytical results are technically reliable and delivered within the required turnaround times to effectively support production, process control, engineering, geology, exploration, and environmental activities.

• Manage the daily operation of the analytical laboratory, ensuring the safe, accurate, and timely completion of assays for mine, exploration, process, metallurgical, and environmental samples.
• Establish laboratory priorities, production schedules, and turnaround-time targets in coordination with Operations, Processing, Geology, Exploration, Metallurgy, and Environmental teams.
• Maintain the laboratory quality management system, including certified reference materials, blanks, duplicates, check assays, control charts, proficiency testing, nonconformance investigations, and corrective actions.
• Review, validate, and authorize analytical results prior to release, ensuring the integrity, traceability, and confidentiality of laboratory data.
• Establish, review, and maintain analytical methods, standard operating procedures, work instructions, and equipment operating procedures.
• Manage onsite environmental testing and environmental sample handling, including preservation, holding times, chain of custody, QA/QC review, and reporting of validated results to the Environmental Department.
• Coordinate work performed by accredited external laboratories, including sample preparation and shipment, chain of custody, turnaround-time monitoring, and review of analytical results.
• Plan laboratory staffing and schedules to meet routine, peak, and emergency workloads, and recruit, train, supervise, and evaluate laboratory personnel while maintaining appropriate competency and authorization records.
• Ensure compliance with applicable health, safety, and environmental legislation, permits, company policies, and laboratory procedures, including the safe management of laboratory chemicals, hazardous materials, equipment, and waste.
• Conduct laboratory safety inspections, participate in risk assessments, investigate incidents and deficiencies, and ensure appropriate corrective and preventive actions are implemented.
• Establish and maintain preventive maintenance, calibration, and verification programs for laboratory instruments and equipment, coordinating repairs and work orders as required.
• Maintain appropriate inventories of reagents, certified reference materials, consumables, critical spare parts, and personal protective equipment.
• Manage laboratory operating and capital budgets, monitor expenditures, and identify cost-control and continuous-improvement opportunities.
• Prepare and communicate laboratory production and analytical reports, QA/QC summaries, safety and maintenance reports, performance indicators, equipment availability, sample backlogs, and significant analytical issues to the Process Manager and relevant departments.
• Investigate disputed results, analytical failures, and significant deviations, ensuring appropriate corrective and preventive actions are implemented. When operationally required, perform laboratory functions for which the Manager is trained and authorized.
