  • Excavating the rockWaihi Gold

    The definition of ore and waste rock depends on the cut-off grade. If the cut-off grade is one gram per tonne (1.0g/t) all rock with more than 1.0g/t of gold will be marked out as ore while all rock which contains less than 1.0g/t of gold will be marked out as waste rock. The cutoff grade can be as low as 0.75g/t.
