  • Mining Valuation Lesson: Cut-Off Grade Theory and

    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.

    1. Introduction. The tonnage, average grade, and cutoff are the basic parameters in mineral resource assessments and mining operations. Research on the inherent relationships between the tonnage, average grade above cutoff and the cutoff has been carried out for decades on the scale of an ore camp, district or ore province.

  • Selection and Grade-Tonnage Relationships

    In practice, blocks are selected according to their estimated value and not according to their true unknown value. In order to avoid serious errors in calculating a grade-tonnage curve, we must be able to define clearly the relationships existing between estimates and the corresponding true values.

Ordinary kriging was used to produce a more conservative and robust resource.

  • 44. Higher Metal Prices – Should We Lower the Cut

    When metals prices are high, we are generally told that we should lower the cutoff grade. Our cutoff grade versus metal price formula tells us this is the correct thing do. Our grade-tonnage curve reaffirms this since we will now have more ounces of gold in the mineral reserve. But is lowering the cutoff grade really the right thing to do?
