Mine trucks: transport economics?

There are around 50,000 giant mining trucks in operation globally. The largest examples are around 16m long, 10m wide, 8m high, can carry around 350-450 tons and reach top speeds of 40mph.

This data-file captures the economics of a mine haul truck. A 10% IRR requires a charge of $10/ton of material, if it is transported 100-miles from the mine to processing facility. Assumptions can be stress-tested overleaf.

Fuel consumption is large, around 40bpd, or 0.3mpg, comprising around 30% of total mine truck costs at c$1.5-2/gal diesel prices. Some lower carbon fuels are c5x more expensive, and would  thus inflate mined commodity costs.

High utilization rates are also crucial to economics, to defray fixed costs, which are c50% of total costs, as our numbers assume each truck will cover an average of 500 miles per day for c20-25 years.
