2014105The cutoff grade of an ore is essentially the lowest grade of an ore that is worth mining. If the ore grade is less than the cutoff grade then a mining company will not make money mining that ore. According to Fellows 2010 the cutoff grade of an ore is one of the main factors in determining the economics of the mine.
