Mining Valuation Lesson: Cut-Off Grade Theory and Practice

Dec 04, 2011However, 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.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
