About The Position

Reporting to Chief Long Range Planning Engineer, the Senior Long Term Planning Engineer is responsible for defining the strategic direction and long-term economic value of the mining operation. This 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. This role will be located at the Copper World Project, approximately 45 minutes southwest of Tucson near Sahuarita, Arizona.

Requirements

Bachelor’s degree in Mining Engineering.
7-10+ years of proven experience in mine engineering in open pit operations.
At least 2+ years as a short/medium term mine planning experience.
At least 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 MinePlan 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.
Must have a current and valid driver's license.

Nice To Haves

A post-graduate degree is considered a strong asset.

Responsibilities

Develop, maintain, and update the comprehensive LOM plan based on the latest resource models, cost data, and geotechnical/regulatory and operational constraints.
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 long-term mine infrastructure, including ultimate pit limits, waste storage facilities, stockpiles, haul roads, and primary crushing/material handling sequencing.
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.
Perform annual Reserve/Resource estimation and reporting.
Prioritizes safety in mine plans and mine designs ensuring that all work supports safe operations, adhering to all relevant safety protocols and regulations.
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.
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.
Translate the long-term strategic models into the foundation for actionable 5-year plans and support the annual budgeting and rolling forecast updates.
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.
Incorporate slope stability parameters, dewatering requirements, and other critical technical constraints into mine designs to ensure safety and practicality.
Prepare technical documentation for Reserve Reporting (e.g., 43-101), permitting, and business case presentations for senior management and stakeholders.
Support the reconciliation process by comparing actual performance to the long-term plan, identifying variances, and updating the plan accordingly
