Reporting to the Mine Planning Superintendent, the Senior Long Term Planning Engineer defines the strategic direction and long‑term economic value of the mining operation. The role develops and maintains the Life‑of‑Mine (LOM) plan, conducts pit/phase optimizations, and performs trade‑off studies that guide major capital investments and operational strategy.

• Strategic Mine Planning & Design
• Life‑of‑Mine (LOM) Plan Development:
  Develop, maintain, and update the comprehensive LOM plan based on the latest resource models, cost data, and geotechnical/regulatory and operational constraints.
• Economic Optimization:
  Conduct ultimate pit limit optimizations, pushback designs, and phase sequencing using strategic planning tools (e.g., Whittle, NPV Scheduler) to maximize Net Present Value (NPV) of the project.
• Design & Layout:
  Design long‑term mine infrastructure, including ultimate pit limits, waste storage facilities, stockpiles, haul roads, and primary crushing/material handling sequencing.
• Long‑Term Mine Scheduling:
  Build and validate long‑term (5‑year and LOM) mine schedules, defining the annual movement of ore and waste and the progression of mining phases.
• Mineral Reserves:
  Perform annual Reserve/Resource estimation and reporting.
• Safety and Compliance:
  Prioritize safety in mine plans and mine designs ensuring all work supports safe operations, adhering to all relevant safety protocols and regulations.
• Cost Modeling:
  Develop and maintain detailed long‑range cost models, incorporating capital expenditures (Cap Ex) for equipment and infrastructure, and operating expenditures (OpEx) for drill/blast, loading/haulage, and processing.
• Scenario & Trade‑Off Analysis:
  Conduct in‑depth economic trade‑off studies (e.g., cut‑off grade optimization, stockpiling strategies, pit expansion timing) using Discounted Cash Flow (DCF) modeling to support business decisions.
• Budget Support:
  Translate the long‑term strategic models into the foundation for actionable 5‑year plans and support the annual budgeting and rolling forecast updates.
• Technical Integration Compliance
• Cross‑Functional
  
  Collaboration:
  
  Act as a key interface between Geology, Geotechnical Engineering, Hydrogeology, Processing, Environmental and Finance to ensure all technical and cost inputs are integrated and aligned within the strategic plan.
• Geotechnical & Hydrological Integration:
  Incorporate slope stability parameters, dewatering requirements, and other critical technical constraints into mine designs to ensure safety and practicality.
• Reporting & Compliance:
  Prepare technical documentation for Reserve Reporting (e.g., 43‑101), permitting, and business case presentations for senior management and stakeholders.
• Reconciliation:
  Support the reconciliation process by comparing actual performance to the long‑term plan, identifying variances, and updating the plan accordingly.

• Bachelor’s degree in Mining Engineering required; a post‑graduate degree is a strong asset.
• 7–10+ years of proven experience in mine engineering in open pit operations, with at least 2+ years as short/medium term mine planning experience and 3+ years in long term mine planning, preferably in a similar operation.
• Expert‑level knowledge of specialized mine planning and optimization software (e.g., Whittle, Hexagon Mine Plan 3D/MPSO, Deswik Go).
• Strong theoretical and practical knowledge of open pit mine optimization principles, NPV modeling, and strategic mine design.
• Competency in financial modelling and economic analysis, including DCF valuation and cost‑benefit analysis.
