  • Break Even Analysis How to Calculate the Cut Off Grade

    When the OPEX is known, you can calculate the minerals 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 isnt available, I refer you to the note at the bottom of this page.

  • Mining Valuation Lesson Cut Off Grade Theory and Practice

    Now, if we go back to the original tonnage grade distribution as shown in our graph, we can see that roughly 6 per cent of our orebody has a grade of less than 1.5 grams per tonne. Obviously when we mine the orebody, we would try and stay away from mining and certainly would not treat the 6 percent of tonnage below the cut off grade.
