UG Operations General Supervisor

About Jerritt Canyon

The Jerritt Canyon deposit was discovered in 1972, and the first gold production from the property occurred in 1981. The Jerritt Canyon property contains 30,821 hectares of mining claims located in the mining-friendly state of Nevada. First Majestic acquired the Jerritt Canyon Gold Mine from Sprott Mining Inc. on April 30, 2021. In May 2023, operations were suspended to prioritize exploration and technical studies.

Jerritt Canyon is now entering a new phase of evaluation and planning, requiring substantial technical support to advance the work necessary for a potential future restart of operations.

The Underground Operations General Supervisor is responsible for leading and coordinating underground mining activities to achieve safe, efficient, and productive gold ore extraction in accordance with the mine plan, operating standards, and applicable regulatory requirements.

This position provides direct leadership to underground supervisors, mining crews, contractors, and support personnel. The General Supervisor is accountable for the safe execution of daily production activities, workforce performance, equipment utilization, ground control practices, ore development and extraction, and effective coordination between Mining, Engineering, Geology, Maintenance, Safety, and other site functions.

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.

• 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.

• 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…
