Sampling techniques



Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

Vacuum Soil Drilling - Geochemical sampling.

Grab sample of bottom of hole (BOH) drill spoil cuttings recovered from vacuum drill hole. Sample material commonly includes the 90cm of material directly overlying drill refusal (where the drill bit is unable to penetrate further. Samples commonly consist of 1-2 kg of cuttings
