Abstract [en]

This paper challenges the traditional notion that mine planners need to plan production at mining rates that result in a low mining cost. For a given mine configuration, a mine that considers increases to its mining rate most often increases mining costs. In an environment in which operations are fixated on cost reduction, a proposal to increase costs may be very difficult to implement. Such a proposal may need to be justified financially because the increase in costs might not be recuperated by the extra production gained. This paper evaluates the net present value (NPV) of the selected range of copper prices for two underground orebodies located at different depths using a production rate of 300,000 tonnes and one that introduces additional costs at 450,000 tonnes per quarter. Discrete event simulation combined with mixed integer programming was used for the analysis. The results shows that, for the low mining rate at the final copper price, an NPV of $755.65M is achieved, whereas an NPV of $773.45M is achieved at a high mining rate. Therefore, even though pushing mining rates beyond traditional limits increases mining costs, pursuing this option at certain commodity prices may be beneficial, particularly when prices are elevated.
