What this role is

Senior on-shift leader overseeing crushing, grinding, and metal extraction operations across a processing plant area. At the Manager II (M2) level, the role owns an established team or sub-function, cross-project coordination and priorities, and drives group delivery and development. Manages a team; sometimes manages leads.

What this level does

  • Lead a skilled operating team across multiple circuits of the processing plant (crushing, screening, milling, thickening, leaching, CIL, recovery), owning tactical shift outcomes.
  • Make appropriate changes in plant processes within known operating parameters to optimize throughput, recovery and efficiency during the shift.
  • Coordinate cross-functionally with maintenance and metallurgy to resolve process upsets and keep circuits running to target.
  • Coach junior supervisors and operators on machine setup, safe operation and regulated qualification progression.
  • Own shift-level compliance with safety, environmental and regulatory obligations, ensuring risk assessments and reporting are maintained.
Knowledge applied
Applies broad operating knowledge across several circuits, exercising judgment within known operating factors to optimize performance.
Complexity & problem solving
Makes process changes within established parameters to address process upsets and efficiency gaps during the shift.
Collaboration & interaction
Cross-functional cooperation with maintenance and metallurgy; leads a skilled operating team.
Typical experience
2–5 years in team leadership or specialist operating roles across processing circuits.

Skills at this level

Safety and Environmental Compliance
Ensures mineral processing operations meet environmental regulations and safety standards, maintaining risk assessments, defect reporting and regulatory standing across plant circuits.
Process Plant Operation
Operates and monitors all areas of the processing plant — crushing, screening, milling, thickening, leaching, CIL and gold/metal recovery — observing meters, gauges and control panels to keep circuits running safely and efficiently.
Process Optimization
Makes changes in plant processes to optimize throughput, recovery and efficiency, tuning operating parameters against production targets and cost.
Machine Setup and Operation
Sets up and operates stationary plant and machinery that grind, crush, cut, saw and slice rocks, minerals and stones according to job specifications.
Malfunction Detection and Maintenance Support
Detects equipment malfunctions from meter and control-panel readings and supports plant and machinery maintenance and repair, reporting plant defects for resolution.
Shift Production Recording
Records information about processing completed during shifts, including quantities, types and dimensions of materials produced, for handover and reporting.
Team Leadership and Mentoring
Manages a mineral processing team, defining roles and responsibilities, mentoring and motivating operators and metallurgists, and driving continuous improvement.
Technical Problem Solving
Solves complex material and process-related problems in the plant, providing technical expertise and coaching to metallurgists, technicians and refiners.
Plant Budget and Cost Management
Owns operating budgets and consumables (grinding media, reagents) for the plant, managing cost per tonne and prioritizing improvement and capital-related spend.
Geometallurgy and Resource Integration
Integrates orebody and feed characteristics into plant operation and equipment selection through familiarity with geometallurgy and resource modelling.
Regulated Qualifications
Achieves and maintains appropriate regulated operating qualifications, such as the MPQC Level 2 Diploma in Mineral Products Mobile Plant Operations, and supports team certification.
Continuous Improvement Program Leadership
Undertakes and sponsors projects and multi-year programs to improve production plant performance, managing consultants and cross-functional stakeholders.
