About Mariana Minerals

Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.

Through its Copper One platform, Mariana Minerals owns and operates the Lisbon Valley Mining Company, a producing open-pit copper mine located in southeastern Utah.

Lisbon Valley Mining Company utilizes modern surface mining methods—including drilling, blasting, loading, and hauling—to deliver ore to its crushing and heap leach processing facilities. Our success depends on safe, reliable equipment performance, supported by a skilled and safety-focused maintenance team.

The Role

The Heavy Equipment Operator plays a critical operational role in supporting mine production through the safe and efficient operation of mobile heavy equipment, including loaders, dozers, excavators, graders, water trucks, and drill rigs.

This position is responsible for conducting equipment inspections, maintaining safe working conditions, contributing to production targets, supporting operational and maintenance teams, and ensuring compliance with MSHA standards and company procedures. The ideal candidate demonstrates strong situational awareness, mechanical aptitude, and the ability to work effectively in a dynamic mining environment.

Safely operate heavy equipment including loaders, bulldozers, excavators, graders, water trucks, and blasthole drill rigs.
Work across all mine areas as needed, including active pits, dumps, haul roads, and process areas.
Operate equipment in a manner that maximizes productivity while minimizing downtime, fuel use, and equipment wear.
Perform and document accurate preshift and postshift inspections on all assigned equipment.
Conduct ground support tasks such as shoveling, spotting, barricading, and general labor when required.
Assist maintenance personnel by communicating equipment issues, supporting troubleshooting, and performing basic servicing.
Maintain clean, safe, and organized operating areas.

Safety & Compliance

Always follow MSHA, OSHA, and company safety procedures, including lockout/tagout, hazard reporting, and traffic rules.
Demonstrate strong hazard recognition skills and actively participate in daily safety meetings.
Ensure equipment operation and ground activities comply with environmental and regulatory expectations.
Report unsafe conditions, equipment damage, and near misses immediately.

Collaboration & Communication

Communicate effectively with supervisors, maintenance, and fellow operators.
Provide clear shift handover notes to ensure continuity between crews.
Participate in task training for new operators and support continuous improvement initiatives.

Desired Qualifications

Ability to learn and apply federal, state, local, and company safety and environmental regulations.
Strong written and verbal communication skills.
Willingness to perform manual labor as needed.
Flexibility to train on additional equipment and roles.
Compliance with all company policies and procedures.
MSHA Surface Miner Training preferred.
Commitment to maintaining a safe work environment.
Must possess or be able to obtain a valid driver’s license.

Physical Requirements

Ability to walk long distances over rough, uneven terrain and climb ladders and structures.
Ability to lift a minimum of 50 pounds.
Ability to work in all weather conditions, including extreme temperatures.
Must wear and utilize all required PPE, including but not limited to:
Hard hat
Steel-toed footwear
Safety glasses
Hi-visibility safety vest
Hearing protection
Respirator (as needed)
Protective clothing/gloves
Must be able to work in environments that may include exposure to fumes, dust, diesel, solvents, sulphuric acid, and other hazardous materials.
