• The successful candidate will demonstrate strong underground mining experience, sound operational judgment, visible safety leadership, and the ability to manage multiple production priorities in a dynamic mining environment.

Responsibilities

• Provide overall leadership and direction for underground mining operations across assigned shifts, crews, mining areas, or production zones.
• Ensure underground production activities are conducted safely, efficiently, and in accordance with the approved mine plan.
• Establish daily and weekly production priorities and communicate clear expectations to supervisors and crews.
• Monitor production performance against planned targets for development, stoping, ore production, ground support, mucking, hauling, and related activities.
• Coordinate underground development and production activities to maintain sufficient mining faces and ore availability.
• Ensure mining activities are sequenced appropriately to support the short-, medium-, and long-term mine plans.
• Supervise and develop underground supervisors and frontline leaders, providing coaching, performance feedback, and accountability.
• Ensure employees and contractors understand and comply with site safety policies, procedures, standards, and applicable mining regulations.
• Maintain a strong field presence underground and promote a culture in which safety is treated as an operational priority.
• Identify and address unsafe conditions, work practices, hazards, and operational risks before they result in incidents.
• Ensure appropriate ground-control practices are followed, including scaling, ground support, rehabilitation, barring, and workplace inspections.
• Coordinate with Mine Engineering and Geology regarding development headings, stope sequencing, ore boundaries, dilution, ore loss, and changing ground conditions.
• Work closely with Maintenance to maximize the availability and reliability of underground mobile and fixed equipment.
• Monitor equipment utilization, availability, productivity, and operating condition and take corrective action when performance falls below expectations.
• Coordinate personnel, equipment, materials, services, and contractors to minimize operational delays and production interruptions.
• Ensure proper ventilation, dewatering, communications, access, and other critical underground infrastructure are maintained.
• Monitor blasting and explosives-related activities to ensure they are performed by appropriately qualified personnel and in accordance with mine procedures and regulatory requirements.
• Ensure ore and waste are correctly identified, handled, transported, and reported to support accurate production and grade control.
• Review shift reports, production data, equipment reports, inspection findings, and other operational information to identify trends and opportunities for improvement.
• Investigate production variances and implement corrective actions to improve productivity, cycle times, equipment utilization, and overall operational performance.
• Participate in incident and near-miss investigations and ensure corrective actions are implemented and sustained.
• Maintain effective communication between shifts to ensure continuity of operations and transfer of critical information.
• Participate in mine planning, budgeting, forecasting, workforce planning, and production scheduling activities.
• Manage operating costs within the assigned area and identify opportunities to improve cost efficiency without compromising safety or production requirements.
• Ensure compliance with environmental, regulatory, permitting, and company requirements applicable to underground mining operations.
• Maintain accurate operational records and ensure required reports are completed in a timely manner.
• Support continuous improvement initiatives involving mining methods, production systems, equipment utilization, workforce productivity, and operational reliability.
• Lead or participate in emergency response activities and ensure underground personnel are familiar with emergency procedures, evacuation requirements, and mine rescue protocols.
• Build effective working relationships with Engineering, Geology, Maintenance, Processing, Safety, Training, Supply Chain, and other departments.
• Promote employee development, succession planning, and competency improvement within the underground operations team.
• Perform other duties and responsibilities as required to support safe and effective mine operations.
• The above responsibilities are representative and may not include all assigned duties.

Requirements

• High school diploma or equivalent required.
• Must be able to obtain ATF clearance.
• Current training/certification in underground mine safety, emergency response, first aid/CPR, and other site-required competencies.
• Additional training in mine ventilation, ground control, blasting/explosives, risk management, or mine safety is highly desirable.
• Experience with incident investigations, hazard identification, and risk management.
• 8–10+ years of progressive underground hard-rock mining experience, preferably in a gold-mining environment.
• 3–5+ years of demonstrated supervisory or management experience in underground mining operations.
• Proven experience supervising underground production and/or development activities.
• Strong working knowledge of underground mining methods, including applicable methods such as longhole open stoping, drift-and-fill, or other methods appropriate to the operation.
• Demonstrated experience with underground development, production drilling, blasting, mucking, hauling, ground support, and stope operations.
• Experience working with underground mobile equipment such as LHDs, haul trucks, development jumbos, bolters, longhole drills, service equipment, and related machinery.
• Experience interpreting mine plans, production schedules, engineering drawings, geological information, and operational reports.
• Demonstrated understanding of ground-control principles and underground geotechnical risks.
• Experience working with mine production KPIs, budgets, cost controls, productivity measures, and continuous improvement programs.
• Experience managing contractors and/or multiple underground crews is strongly preferred.
• Experience in mechanized underground hard-rock mining is highly desirable.
• Experience working in a high-risk industrial environment with strict safety and regulatory requirements.
• Demonstrated ability to make sound operational decisions under changing ground, equipment, production, and workforce conditions.
