Strategic Cut-off Grade Policy Optimizer

GeoMine OptimCut (OptimCut) is a dynamic cut-off grade and production rate strategy optimizer. Given a set of nested pits or a stope design, a user-defined dollar formula (expressed as a function of metal price, recovery, fixed and/or variable costs of mining, processing, transportation and refinery. etc.), OptimCut finds N-best yearly cut-off grade and production rate policies (strategies), each of which maximizes NPV over the life of the mine while respecting the precedence constraint using a Constrained Dynamic Programming algorithm based on the Principle of Optimality. The output of OptimCut is a Life-Of-Mine Schedule that can also be optionally used as input to iScheduler for subsequent production scheduling.

Key Benefits

  • Powerful: create constrained, unconstrained or static cut-off grade and production rate policies. Metal price can vary over time, so can mining, processing, transportation and any other costs.
  • Scalable: multi-threaded implementation utilizes all available CPU cores to speed up calculations for large projects.
  • Flexibile: ability to define your own dollar formula to adapt to your specific mining project.
  • Easy to use: seamless workflow within the integrated GeoMine workspace that allows you to compare and contrast multiple strategies side-by-side.
