Principal, Processing
Reports to: Head of Technical Services

About the Opportunity
Our client is a private mining company backed by a mining-focused private equity firm with a 14-year track record. They hold two major assets: an operating open-pit mine in the middle of a milling restart that will multiply its production profile, and a large-scale development project with lowest quartile projected costs and a mine life beyond 10 years. Both are moving fast, and both need processing leadership that can keep pace.

That's where this role comes in. As Principal of Processing, you'll be the company's foremost authority on mineral processing, setting the technical agenda across both properties and making sure every processing decision gets executed with precision and urgency. This isn't a passive oversight seat. It's a role for a technically authoritative leader who spots gaps, challenges the status quo, and pushes teams to deliver at their highest level. The role can be based in Toronto, ON or the Southwest US, with 50-75% travel.

What You'll Do
Processing Strategy & Technical Leadership

Own and drive the overall processing strategy across both properties, keeping it aligned with business objectives and production targets.
Serve as the company's technical authority on mineral processing, flowsheet design, comminution design, and plant optimization.
Lead the identification and implementation of process improvements that deliver measurable gains in throughput, recovery, and cost efficiency.
Evaluate and challenge existing processing assumptions, continuously seeking better approaches and technologies.
Provide technical direction on capital projects tied to processing infrastructure, plant upgrades, and capacity expansions.

Performance Accountability & Team Development

Set high-performance expectations across processing teams and hold individuals accountable for delivery against KPIs and targets.
Push teams to identify and close performance gaps, challenging complacency and expecting excellence at every level.
Lead, mentor, and develop the Principal of Metallurgy and the broader processing team, building technical depth across the organization.
Conduct regular critical reviews of processing performance at both properties, escalating issues and driving swift corrective action.
Foster a culture of urgency, ownership, and continuous improvement within the processing function.

Process & Metallurgy Optimization

Collaborate on all comminution and metallurgical programs, including test work, variability studies, and process audits across both sites.
Make sure comminution and metallurgical data is properly interpreted and translated into actionable improvements on the plant floor.
Partner with the Principal of Metallurgy to align metallurgical findings with processing operations and drive implementation of recommendations.
Review and approve technical reports, metallurgical studies, and processing documentation to ensure rigor and accuracy.

Cross-Functional Collaboration & Stakeholder Engagement

Act as the primary processing point of contact for the Head of Technical Services, providing clear, candid, and timely reporting.
Collaborate closely with mine operations, geoscience, and projects teams so processing requirements are built into planning decisions.
Represent the processing function in executive and board-level discussions, delivering confident, data-driven insights and recommendations.
Engage with external consultants, technology providers, and industry bodies to keep the company at the forefront of processing practice.

Health, Safety & Environmental Compliance

Champion a zero-harm safety culture within all processing operations, ensuring compliance with all regulatory and company HSE standards.
Ensure processing facilities and practices meet all environmental obligations and permit conditions.
Lead incident investigations related to processing operations and make sure learnings are captured and embedded across both sites.
