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.

• Ensure all work is conducted safely and in compliance with company policies, mine standards, and applicable health and safety regulations.
• Conduct workplace inspections, pre-shift meetings, toolbox talks, and safety observations.
• Identify and address hazards, unsafe conditions, and operational risks, including ground-control and ventilation concerns.
• Monitor underground mining activities such as drilling, blasting, mucking, hauling, ground support, scaling, development, and production stoping.
• Coordinate equipment, personnel, materials, and services to maintain efficient underground operations.
• Monitor daily production against planned targets and take corrective action when required.
• Work closely with Mine Planning, Engineering, Geology, Maintenance, Ventilation, and Safety departments to resolve operational issues.
• Ensure development headings and production areas are prepared and maintained to required design, quality, and ground-control standards.
• Monitor ore extraction and dilution, ore/waste handling, and adherence to grade-control requirements.
• Promote efficient equipment utilization and minimize operational delays, downtime, rework, and unnecessary costs.
• Ensure crews follow approved work procedures, operating standards, blasting protocols, and ground-control practices.
• Investigate incidents, near misses, equipment damage, and production interruptions, and participate in corrective-action programs.
• Maintain accurate shift reports, production records, inspection documentation, and other required operational records.
• Coach, mentor, and develop employees to improve technical capability, safety performance, productivity, and accountability.
• Manage shift handovers and communicate operational priorities, hazards, equipment status, and production performance effectively.
• Support continuous-improvement initiatives focused on safety, productivity, cost control, and mining efficiency.
• Demonstrate visible safety leadership and foster a workplace culture based on accountability, teamwork, and operational discipline.
