In this study, a set of geological simulations of the LabMag taconite deposit in Labrador, Canada was generated in order to quantify the geological variability in an existing mining schedule and assess the schedule’s performance. Subsequently, a production schedule optimization based on stochastic integer programming (SIP) was developed to improve mine profitability while simultaneously managing the risk of production tonnage and quality deviations.
