About Us:

Harris Exploration, a division of Earth Drilling, is a trusted source for drilling and installation services in California, Nevada and Arizona with certifications recognized by the International Ground Source Heat Pump Association. We specialize in a variety of drilling solutions, from mineral exploration to water well recovery and geotechnical engineering. Our team of professionals use cutting-edge dual tube RC technology, wireline core methods and more for obtaining soil and rock samples with precision accuracy.

About the Rig Mechanic position:

We are looking for an experienced Rig Mechanic to perform hands-on maintenance, repairs, and troubleshooting on a fleet of RC and Diamond drills, support equipment, and heavy-duty diesel components. This role is heavily field-based and requires someone who understands the unique demands of exploration drilling. This is not an entry-level position — we are seeking a mechanic who knows the difference between a rod loader issue, a booster vs. aux compressor problem, or a top-drive hydraulic failure on a Foremost or Schramm rig.

Job Responsibilities:

• Perform diagnostics, maintenance, and repairs on:
• RC rigs (Schramm 685/450, Foremost Explorer 1500, etc.)
• Diamond/Sonic rigs (Diedrich, Boart, TSI150 CC, etc.)
• Air systems: 900/350s, boosters, rotary screw compressors
• Diesel engines (CAT, Cummins, Detroit)
• Hydraulic systems, pumps, cylinders, and controls
• Conduct scheduled services and preventative maintenance using MaintainX workflows.
• Support field supervisors in troubleshooting real-time breakdowns to minimize downtime.
• Maintain accurate service logs, parts usage, and field repair notes.
• Work safely in MSHA-regulated mine environments.
• Assist with rig moves, inspections, and pre-deployment mechanical checks.
• Communicate clearly with supervisors, rig managers, and parts/purchasing personnel.
• Participate in safety meetings and contribute to continuous improvement.
• Other duties as required.

Job Requirements:

• 5+ years experience as a heavy-duty mechanic, rig mechanic, or drill mechanic (required).
• Proven experience working on RC and/or Diamond/Core rigs (required).
• Strong understanding of hydraulic and pneumatic systems.
• Experience with diesel engines and air compressors common to drilling.
• Ability to fabricate, weld, and perform field-fit repairs is an asset.

MSHA 5000-23

(or willingness to obtain before deployment).

• Valid driver's license (CDL is an asset).
• Ability to work on remote mine sites and travel as required.
