processing cost is then equal to the value of the resulting mineral after processing minus the sales cost. Finding the OCOG is a bit more complicated because first, the opportunity cost of maintaining unexploited reserves has to be calculated, and then added to the processing cost. However, this value will automatically optimize the NPV and IRR.
