Strategic Mine Planning solutions for Open Pit Mines.

Answering the Key Questions – Where to start the exploitation? What is the best method? By identifying the BEST STARTING POINT and BEST MINING DIRECTION for an OPTIMAL PRODUCTION PROGRAM.

Net present value (NPV) is a cash flow to which a discount rate is applied, set according to the risk level or profitability requirement of a project.

The moment in which the optimization is carried out is very important to maximize the value, because of the impact of the discount rate on it.

Regarding maximization of the NPV, some of the key decisions about the exploitation of an open pit deposit are the starting point and the orientation of the mining sequence. This strategic decision ensures a result located close to the limits of the efficiency frontier through a sequence with both better economic and operational performances.

By implementing GEOVIA Whittle and SIMULIA Isight solutions, it is possible to create, in a few hours, a value map for a grid of starting points and mining directions (Fig. 1).
