Mining Valuation Lesson: CutOff 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.

Methods for calculating the minimum amortization tonnage and

Therefore, amortization tonnage can be expressed as a function of mining rate. The amortization tonnage is calculated for a series of mining rates, one of which will indicate a minimum tonnage. Part II describes a procedure for calculating the optimum mining rate to obtain maximum present value of an ore body, when mining rate is the only variable.

Cutoff grade estimation QueensMineDesignWiki

The Grade Tonnage Curves display the tonnage above the cut-off grade and average grade of a deposit relative to cut-off grade. As the criteria for ore classification becomes more selective, the tonnage above the cut-off grade of the deposit decreases. Conversely, as the cut-off grade is lowered, the tonnage of the deposit increases.

Mineral resource estimation Wikipedia

Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.
