Job description

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.

• Supervise installation, commissioning, testing, and maintenance of electrical and instrumentation systems.
• Support installation and maintenance of underground power distribution, substations, transformers, switchgear, MCCs, motor starters, VFDs, lighting, pumps, ventilation systems, and other mine infrastructure.
• Oversee instrumentation and control systems, including sensors, transmitters, process controls, monitoring systems, and PLC-based equipment.
• Review electrical drawings, schematics, one-lines, control diagrams, and equipment documentation to support field activities.
• Coordinate with engineering and maintenance personnel on equipment modifications, system upgrades, and capital projects.
• Monitor work quality and verify installations and repairs meet design specifications and applicable standards.
• Manage contractors and subcontractors performing E&I work underground.
• Maintain accurate maintenance records, inspection reports, work orders, and documentation.
