Au – Chemical symbol for gold.

Auger Drilling – A drilling method in which the sample is brought to the surface via a helical or spiral rods.

g/t – grams per tonne

ppb – parts per billion. E.g. 1000 ppb Au equals 1 ppm Au, or 1 g/t Au.

ppm – parts per million, equivalent to g/t.

RAB Drilling – Rotary Air Blast drilling. A drilling method in which the sample is brought to the surface outside of the drill rods using compressed air.

RC Drilling – Reverse Circulation drilling. A drilling method in which the sample is brought to the surface inside the drill rods using compressed air, reducing contamination

Diamond Drilling– A rotary type of rock drill which cuts by abrasion rather than percussion. The cutting bit is set with diamonds and attached to the end of long hollow rods through which water is pumped to the cutting face.
