  • Communicate process inputs and requirements to engineering, permitting, and other project stakeholders (internal and external as required).
  • Partner with the geology team to understand the geo-metallurgy characteristics of the ore body, develop a geo-metallurgical model, and determine how to respond and maximize value.
  • Support and review modeling and simulation of the proposed flowsheet configuration.
  • Partner with the Technology department to identify and implement technologies that are appropriate for managing and optimizing operation and generating value for the business.
  • Develop CAPEX and OPEX budget assumptions for the Processing department as it relates to studies associated with the Clark deposit.
  • Lead and organize trade-off studies to identify the best path forward to maximize project value.
  • Ability to travel to various locations as required by the project, including external laboratory facilities to verify and validate trade-off study data and assumptions on a regular basis.
  • Review PFDs, P&IDs, and conduct HAZIDs.
  • Work with engineering groups and third-party contractors to ensure successful delivery of Clark within scope, schedule, and budget.
