When the OPEX is known, you can calculate the mineral’s cut off grade, which is the break even grade, below which it is not economically viable to mine the ore. To find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn’t available, I refer you to the note at the bottom of this page.

In single-product and single-process mode, the optimum cut-off grade and the net present value of production are calculated for each year of the mine''s life. After validating the outputs of the model, the implementation of the computer model based on the data of Gol Gohar iron mine No.1 in a five-year plan was carried out.

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is

Cutoff grade is defined as the grade that is normally used to discriminate between ore and waste within a given orebody. Although the definition of cutoff grade is very precise, the choice of a cutoff grade policy to be used during an exploitation of a deposit is not. Use of simply calculated breakeven cutoff grades during the production will in most instances lead to sub-optimum exploitation
