Net Present Value

The NPV objective is used to perform value calculations during a schedule optimisation, which generates higher values based on costs and revenue.

The NPV tab is used to assign more complex economic costs to the setup. These include:

  • Discount rate — The value lost per period.
  • Mining cost — The cost to physically remove material.
  • Processing cost — The cost associated with mill usage.
  • Rehabilitation cost — The cost per ton applied to transport material to a waste utility.
  • Rehandle cost — The cost per ton applied to material taken from a stockpile.
  • Reclaim — The cost per ton to transport material from a stockpile to a mill.
  • Recovery— The percentage for recovering material from a stockpile.

The Calendar > NPV tab is used to assign basic NPV costs and value on a per period basis.
