About the role

  • You will establish company-wide standards and best practices for short-, medium-, and long-term mine planning, ensuring consistency, rigor, and decision-quality across all assets.
  • This is a senior technical leadership role that sits at the intersection of geology, mine engineering, economics, and corporate strategy.
  • You will influence what projects get built, how they are sequenced, and how value is maximized over time.

Responsibilities

  • Lead technical mine planning input for project screening, opportunity evaluation, and portfolio-level decision making
  • Develop high-level mine concepts, production profiles, and sequencing options to support investment, acquisition, and development decisions
  • Partner with geology, metallurgy, and commercial teams to evaluate trade-offs between scale, timing, risk, and value
  • Own and develop long-range (LOM) mine plans that maximize NPV, operational flexibility, and strategic optionality
  • Perform multi-pit optimization, phase sequencing, and cutback strategy development across complex deposits
  • Evaluate alternative development strategies, mining rates, and sequencing scenarios to support robust decision making
  • Define and maintain company-wide standards, methodologies, and assumptions for short-, medium-, and long-term mine planning
  • Establish consistent approaches to mine design, scheduling, economic evaluation, and scenario analysis across all projects

Requirements

  • 5+ years of mine planning experience, with a strong emphasis on long-range planning, optimization, and strategic evaluation
  • Strong proficiency with modern mine planning and optimization tools (e.g., Deswik, Whittle, Vulcan, MinePlan, Leapfrog)
  • Experience evaluating complex, multi-pit or multi-deposit mining projects
  • Ability to think at both the technical and strategic level, connecting mine plans to capital decisions and long-term value creation
  • Experience working in fast-moving, project-driven or greenfield environments
  • Experience supporting early-stage studies (conceptual, PEA, PFS, FS) and corporate-level project evaluations
  • Demonstrated expertise in pit optimization, phase design, sequencing, and economic trade-off analysis
  • Strong communication skills and confidence operating as a senior technical authority
  • Professional Engineer (P.Eng or equivalent), or eligibility

Nice to have

  • Bachelor's degree in Mining Engineering or a closely related field (Master's preferred)
