Strategic Mine Planning solutions for Open Pit Mines.
What plant size maximizes profit? What mine capacity is more efficient?
Net Present Value (NPV) represents the cash flow to which a discount rate is applied, set according to project risk level or profitability requirement.
The Strategic Mine Planning (SMP) issue of an open pit project is generally defined looking for NPV maximization by searching an optimized extraction sequence.
That sequence must respect operational restrictions such as slope angles, limits and drilling rates, as well as mineral mining and processing capacities.
By implementing GEOVIA WHITTLE and SIMULIA Isight solutions, it is possible to apply the Hill of Value concept, establish ranges of mining, processing and cut-off grade capacities, with the aim of increasing value and evaluate its robustness and reliability, against the range of design variables that were selected (Fig. 1).
