In mining, grade is king. Across the commodity spectrum, some of the most anticipated results — which can determine the scope of a mining project — are assay values from drill testing.

As one of mining’s most influential figures, Robert Friedland, sums it up:

“Mining 101. High grade is good. Low grade is bad.”

“The higher the grade, the smaller the environmental footprint, Friedland has said. “The higher the grade, the smaller the plant; the less the electrical consumption, the smaller the labour force, the smaller the tailings pond, the less the global warming gas per unit of metal produced.”

The value of the ore is calculated by multiplying the contained metals and minerals per tonne in the proven and probable reserves by the ruling price for the commodities.

Silver and gold shine on the top ten list of mines with the most valuable ore, compiled with data provided by our sister company Miningintelligence.
