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.

Cut-off grades are used to determine the point at which material becomes economically valuable. Therefore, they are necessary to define the amount of ore in a deposit. The classification of ore depends entirely on cut-off grade. Increasing the cut-off grade places a stricter requirement on what can be considered ore. This decreases the amount

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
