Mechanical Superintendent

Description

The Mechanical / Maintenance Superintendent is responsible for leading all maintenance and mechanical activities supporting Milford Mining Company’s mining and mineral processing operations. This role provides hands‑on and strategic leadership to ensure plant and mobile equipment reliability, safe work execution, and continuous improvement across crushing, grinding/milling, flotation, acid leach, solvent extraction and electrowinning operations. The Superintendent will oversee maintenance personnel, contractors, and maintenance systems while working closely with Operations, Engineering, and Health & Safety to maximize equipment availability and production performance.

This position requires proven leadership capability, advanced mechanical maintenance expertise, and a strong understanding of mineral processing equipment and systems.

• Lead, mentor, and develop Maintenance Team Leaders, planners, and trades personnel (mechanics, electricians, welders).
• Establish clear expectations for safety, performance, and accountability across the maintenance team.
• Foster a strong safety culture aligned with Company policies and MSHA requirements.
• Coordinate and manage contractors for specialized maintenance and shutdown activities.

• Direct preventive, predictive, and corrective maintenance programs for plant and site equipment.
• Ensure high availability and reliability of critical assets across all processing areas, including:
  • Crushing systems (primary, secondary, and tertiary crushers)
  • Grinding and milling equipment (ball mills, grinding circuits, cyclones)
  • Sulfide flotation circuits (flotation cells, agitators, blowers, launders)
  • Acid leach systems (leach tanks, pumps, piping, heaters, agitators)
  • Solvent extraction (SX) equipment (mixer‑settlers, pumps, organic handling systems)
  • Electrowinning (EW) systems (cells, rectifiers, cathode handling equipment)
  • Pumps (slurry, process, centrifugal, and positive displacement)
  • Electric motors, drives, and control equipment
  • Conveyors, gearboxes, and material handling systems
• Lead root cause failure analysis (RCFA) and implement long‑term corrective actions.
• Develop and manage maintenance shutdown planning and execution.

• Oversee welding, fabrication, and structural repairs to ensure compliance with engineering standards and quality requirements.
• Ensure proper welding procedures, qualifications, and inspections are followed.

• Develop and manage maintenance budgets, including labor, parts, and contract services.
• Optimize spare parts inventory and maintenance materials management.
• Track and report key maintenance KPIs (equipment availability, downtime, MTBF, MTTR, cost control).

• Apply mechanical and process engineering principles to improve equipment performance, maintainability, and safety across crushing, grinding/milling, flotation, acid leach, solvent extraction, and electrowinning operations.
• Support process improvements and debottlenecking initiatives across oxide and sulfide processing circuits.
• Participate in equipment selection, design reviews, and commissioning of new or modified systems.
• Collaborate with Operations and Process Engineering to address throughput, recovery, and reliability constraints.

• Ensure all maintenance activities comply with MSHA regulations, company safety policies and environmental requirements.
• Lead safety meetings, job hazard analyses (JHAs), and incident investigations related to maintenance activities.

• Strong leadership and team development skills
• Practical, hands‑on mechanical aptitude
• Ability to troubleshoot complex mechanical and process‑related issues
• Excellent planning, organizational, and communication skills
• Data‑driven decision‑making and continuous improvement mindset
• Ability to work effectively in a remote, operations‑focused mining environment

• Combination of office, plant, and field work in an active mining and processing environment
• Must be able to work extended hours during shutdowns and critical maintenance events
