Pit Optimization - More Than Just a "NPV vs RF" Graph - Kuchling

Oct 14, 2021Often 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.
