ORE DEPOSIT TERMS

The cut-off grade is the arbitrarily defined lowest grade which will be mined from an ore ore deposit and usually defines the boundary of the deposit For example if the average grade of a porphyry deposit is 05 Cu the cut-off might be 02 Cu any rock with a grade below 02 Cu would be waste Reserves...
