A multivariate geochemical baseline survey of soils from southern New Zealand has been completed. Soil samples were collected from 0 to 30 cm 'A-depth' and 50-70 cm 'B-depth' at 348 sites on an 8 km-spaced grid covering 40,000 km 2 of the Southland and southern Otago regions. The sub-180 μm fraction of all samples was analysed by inductively coupled plasma mass spectrometry ...

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 st...

The prolonged droughts on the goldfields of the South Island during 1906 and 1907 have proved disastrous to the alluvial gold-mining industry, and the annual value of the gold-production from this source, which formerly was recorded in millions of pounds sterling, during 1907 only amounted to £63,284, independent of the gold-dredging returns.
