How reliable is the ultimate pit generated by MaxiPit?
An independent firm of international mining consultants was commissioned to compare the ultimate pit generated by MaxiPit (and hence NPV Scheduler) against the ultimate pit generated by its most expensive competitor, Whittle Four-D. You can download the consultant’s report from the product page to get all the details. To quote from the report… “The results of the comparisons show no significant difference between the optimum pits generated by Maxipit or Whittle. The differences that do exist in product tonnage and metal are negligible, the higher differences in the total pit volume is a reflection of slope modeling accuracy and is to be expected.” And to quote from an in-house evaluation by CVRD, the largest iron ore mining company in Brazil… “Comparing the results of MaxiPit and W4D with exactly the same slope sub-regions, there were not significant differences in the surface topography of the ultimate pits generated.
