Abstract:
The PhotonAssayTM Max is an instrument utilising high-energy X-rays but reimaged for the modern world with full robotics and ability to keep up with the high demands of mining. Since Pierre Gy’s introduction of sampling theory into the gold mining industry, many researchers have struggled with limitation of the available techniques, like fire assay and cyanide leach, and their impact on the fundamental errors in relating the assay value to the drill hole or deposit. Gold provides some unique sampling challenges over other commodity elements as it is malleable and is difficult to homogenise by pulverisation.
