Mining Valuation Lesson: Cut

Dec 04, 2011 However, eventually, the shorter mine life becomes too significant and the NPV declines. Looking at the table, you can clearly see that a cut-off grade of 4.0 reduces the relative NPV down to 0.6. Again, remember that increasing cut-off grade reduces your mine life as you “throw away” the lower grade ore in your calculations.
