The position will have responsibility to support exciting, complex projects throughout the world ranging from approximately $1 million to $10+ billion, including open pit, and underground mining projects, process plants, tailings facilities, water management systems, site infrastructure, utilities, material handling systems, mine support facilities, sustaining capital programs, an large multi-phase study programs. The successful candidate will be responsible for the coordination and development of cost estimates and schedules for design teams at traditional project development milestones.
This role is intended for an experienced senior estimator with experience leading large capital cost estimates for mining studies, major project development programs, and execution-stage mining projects. The successful candidate will have demonstrated experience coordinating multi-discipline estimates for mining, mineral processing, infrastructure, tailings, water management, reclamation, closure, and site development scopes. Experience leading estimates for PEA, PFS, FS, execution, sustaining capital, and large projects is strongly preferred. Contractor-side, construction, field, or preconstruction experience is considered a significant asset.
