About the Strip Ratio Calculator
This calculator reports a unit-consistent arithmetic ratio of waste material to ore material.
Formula
Strip ratio = waste material ÷ ore material.
Example
300 waste units divided by 100 ore units gives a strip ratio of 3:1.
Notes
A strip ratio alone does not model geology, sequencing, costs, slope stability, equipment or mine design and is not operational guidance.
