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: Prioritizes safety in mine plans and mine designs ensuring that 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 (CapEx) for equipment and infrastructure, and operating expenditures (OpEx) for drill/blast, loading/haulage, and processing
