About Mount Milligan Mine Located approximately 155 kilometres northwest of Prince George in central BC, the Mount Milligan Mine is a conventional truck-shovel open-pit copper and gold mine and concentrator with a 60,000 tpd capacity copper flotation processing plant. Mount Milligan operates with comfortable camp accommodations equipped with private washrooms, TV, Wi-Fi, an onsite gym, and other recreational activities. Bus transportation to and from site is provided free of charge from several locations within the region. Mount Milligan promotes a drug and alcohol-free workplace and has adopted a zero-tolerance policy with respect to alcohol or unauthorized drugs on site. About The Opportunity Mount Milligan is seeking a Superintendent, Metallurgy to lead the metallurgical, process engineering, and on-site assay functions to generate accurate data, maximize metal recovery, optimize plant performance, and ensure stable, efficient, and safe operation of the processing plant. This role provides technical leadership across comminution, flotation, gravity recovery, dewatering, sampling, and quantitative assaying within the mine. This role is critical to Mount Milligan’s copper–gold concentrator performance, requiring strong mine-to-mill integration, ore variability understanding and management, concentrate quality control, and leadership of recovery forecasting to support safe and profitable operations. This is a camp based position working a 7 days on/7days off schedule. Key Responsibilities Metallurgical & Process Performance Lead daily/weekly metallurgical monitoring to optimize throughput, recovery, concentrate grade, and reagent consumption. Analyze mill KPIs (grinding performance, flotation response, gold recovery, recovery-by-size curves, etc.) and implement improvement strategies. Manage metallurgical testwork programs including variability testing, reagent scheme development, grinding/circuit optimization, and geometallurgy. Maintain the assaying, metallurgical balance, metal accounting systems, and reconciliation with the mill. Lead metallurgical response strategies to changes in ore and mineralogy. Technical Leadership & Strategy Coordinate with corporate resources and collaboratively provide long-term strategic direction for process improvements, technology upgrades, debottlenecking, and cost reductions. Contribute to metallurgical aspects of life-of-mine planning including ore blending, ore characterization, and processing forecasts. Support capital project development (scope, design criteria, commissioning oversight, operational readiness). Champion advanced process control, machine learning, and real-time metallurgy. Drive automated KPI dashboards and decision support tools. Support commercial team on concentrate performance and payable metals. Operational Support Provide coaching and support to plant operations to troubleshoot processing challenges. Oversee metallurgical sampling programs, laboratory workflows, QA/QC protocols, and data integrity. Ensure optimal operation of major process equipment—SAG/ball mills, crushers, flotation cells, thickeners, filters, gravity circuits, and reagents systems. Provide coaching and guidance to Mill Operations where required. Provide leadership during major shutdowns, commissioning, and ramp-up. Partner with Reliability to define triggers for functional failure and major component replacement. Safety, Compliance & Risk Management Compliance with BC Mines Act, environmental permits, and site safety systems. Promote a strong safety culture and ensure compliance with all operational, environmental, and metallurgical standards. Evaluate and mitigate metallurgical risks including ore variability, water quality, reagent changes, equipment constraints, and environmental compliance.
