Optimisation of metallurgical plant sampling procedures

2020-7-21  The sampling process must provide information that allows decisions to be made that optimise the profit of the operation. Assuming a 5 Mt/y operation at an average grade of 1.5 g/t of gold, a 1% change in recovery has a direct revenue impact of NZ$3.6M dollars (assuming a NZ$1500/oz value). This is an equivalent change of 0.015 g/t in the FFT stream. It is therefore easy to justify suitable efforts and expenditure to make sure that the FFT
