Pit Optimization More Than Just a “NPV vs RF” Graph
网页2021年10月14日 Often in 43-101 technical reports, when it comes to pit optimization, one is presented with the basic “NPV vs Revenue Factor (RF)” curve. That’s it. Revenue Factor represents the percent of the base case metal price (s) used to optimize for the pit. For example, if the base case gold price is $1600/oz (100% RF), then the 80% RF is $1280/oz.

Post-pit optimization strategic alignment SciELO
网页This analysis requires the cut-off grade to be fixed. Traditional open pit scheduling uses a resource model, assuming a fixed cut-off to determine a series of nested pits, in which a given price is used to define one pit and increasing prices correspond to larger pits. These pits are used to select the optimal pit.
