Assay Lab Superintendent - OKO Gold Project

About the role

G Mining Ventures (GMIN) acquired the OKO West gold project in northwest Guyana in July 2024. The Assay Lab Superintendent is accountable for the safe, accurate, timely and cost-effective operation of the site analytical laboratory, supporting Process, Mine Operations, Geology, Metallurgy, Environment, Engineering and other internal customers while maintaining quality systems, competent staffing, equipment availability and reliable analytical data. The role combines office and laboratory work in a mining environment, with regular exposure to plant equipment, noise, dust and high-temperature furnaces, and may require extended hours.

Key responsibilities

• Plan and direct laboratory activities to meet turnaround times, production priorities and service levels.
• Ensure analytical methods, sample preparation, quality-control procedures, result validation and data reporting are followed.
• Lead staffing, crew scheduling, competency development, performance management, succession planning and training.
• Provide technical oversight of fire assay, sample preparation, wet chemistry, instrumental analysis, environmental testing and other approved activities.
• Monitor QA/QC performance, investigate non-conformances and failures, authorise corrective actions and escalate data-quality concerns.
• Maintain procedures, work instructions, forms, records and controlled documentation.
• Coordinate with Process, Geology, Metallurgy, Environment, Maintenance, Supply Chain, IT, HSE and external providers, and initiate maintenance work orders.
• Oversee safety inspections, risk controls, chemical management, waste handling, housekeeping and emergency readiness.
• Monitor consumables, inventory, procurement priorities, operating costs and budget performance.
• Keep instruments, equipment, software and data systems available and fit for purpose, including LIMS interfaces.
• Report performance information and lead improvements in analytical performance, workflow, productivity, cost, safety and reliability.
• Manage external laboratories and contractors used for overflow, specialist analyses, calibration, maintenance or verification.
• Provide leadership to the Power Plant Team and lead, mentor and develop lab workers, technicians and supervisors.

Required profile

• Minimum 12 years of working experience, including 8-10 years at a supervisory level.
• Bachelor's degree in Chemistry, Analytical Chemistry, Metallurgy, Geochemistry or a related technical discipline; extensive mine-assay laboratory experience may be considered instead.
• Significant experience in a mine-site analytical laboratory with supervisory or management responsibility.
• Knowledge of a language other than French, as sites are international.

Required skills

• Precious-metal assaying, sample preparation, wet chemistry and common analytical instrumentation.
• Laboratory QA/QC, statistical review of analytical data, method control and investigation of analytical failures.
• Management of people, priorities, budgets, contractors, equipment availability and multiple internal customers.
• Working knowledge of laboratory information systems, electronic data management and standard business software.
