Job Description

About the Role

You will be the primary person responsible for the condition of our surface and underground heavy equipment. You will work between the Portal and Shaft sites, diagnosing problems and implementing repairs. Parts for some of the older underground equipment are scarce, so repairing, rebuilding, cross-referencing, and fabricating are part of the daily work.

• Perform preventive maintenance and repairs on all mobile and fixed equipment
• Diagnose and repair air motors, diesel engines, drivetrains, hydraulics, brakes, and steering
• Weld and fabricate replacement parts when originals cannot be found
• Source, identify, and cross-reference parts for discontinued machines
• Keep maintenance records and complete required equipment inspections under MSHA and Cal/OSHA standards
• Work alongside the Miners and Support Technicians to proactively prevent downtime

What We Are Looking For

• Strong work ethic, reliability, and the ability to take direction and work independently
• Five or more years of hands-on mechanic experience on underground mining equipment
• Direct experience with Eimco rocker shovels, Wagner Scooptrams, mine locomotives, and slushers.
• Strong diesel engine, hydraulic, and pneumatic troubleshooting skills
• Welding and fabrication ability, and the habit of fixing a problem rather than replacing the part
• Deep electrical knowledge
• Ability to read old manuals, parts books, and prints
• MSHA Certificate or willingness to complete MSHA Part 48 new miner training
• Comfort working underground, in tight spaces, and outdoors year-round in variable weather and terrain
• Valid driver's license and reliable personal vehicle, with the ability to commute to the mine site, in the mountains about 30 minutes east of Pike, CA

The Equipment You Will Keep Running

We have a mixed assortment of equipment. Much of the surface equipment is modern but most of the underground equipment is older, largely mechanical and hydraulic, and in many cases long out of production. Most mechanics trained on current large-mine equipment have never seen them. We need someone who has.

• Eimco 12B air-powered rocker shovel muckers
• Diesel mine locomotives
• Battery mine locomotives
• Slushers, tuggers, & hoists
• Wagner HST-1A Scooptrams (underground LHD loaders)
• Surface equipment: wheel loaders, backhoes, telehandlers, and dump trucks
• Supporting systems: compressed air lines, air compressors, pneumatic rock drills, mine pumps, and electrical systems

Good to Have

• Experience with air-cooled Deutz diesel engines
• Prior work at a small, remote, or older underground mine
• Your own mechanic's tools
• Forklift certification

Schedule and Compensation

• Full-time with overtime
• 10 to 12 hour shifts, 4 to 6 days per week
• $40 to $55 per hour, depending on experience
