30 Seconds of Info – Sampling theory and practice:
Should you use Aircore samples in your resource estimate? If carried out to high standards, Aircore samples can approach RC in their level of representivity, although it is not suitable for all commodities and lithologies. It is always worthwhile looking at the relationship between Aircore and other sampling types (RC or DD) within an area where there is more-or-less equal representivity of both sample types; there should be no bias over the range of reasonable ‘ore-grade’ values.
This week’s 30 Seconds of Info comes from Ian Glacken – Director of Geology.
