Grade Tonnage Curve: How Far Can It Be Relied Upon? - University of Kansas

point of view continuity means a grade distribution and geometric characteristics of the mineralization which allows mining to take place under certain technological conditions. The traditional grade tonnage curve represents an optimistic scenario since it considers that all tonnage above one cutoff is available to be mined.

Making the grade: understanding exploration results

As a rule of thumb, open pit mining can process ore for $10 per tonne and, where the ore grade is more than double that at $20 per tonne, results would be economic. Consider that 1% of a metric tonne is 22 pounds. Then, for a commodity worth about $1 per pound such as zinc, 1% zinc worth $22 per tonne becomes interesting.
