AgChemical symbol for silver
Aircore DrillingReverse Circulation drilling method, using a blade bit. A drilling method in which the sample is brought to the surface inside the drill rods using compressed air, reducing contamination
AuChemical symbol for gold
Auger DrillingA drilling method in which the sample is brought to the surface via a helical or spiral rods
CuChemical symbol for copper
Diamond Drilling (DD)A rotary drilling method with diamond impregnated bits to produce a solid, continuous core sample of the rock
g/tGrams per tonne
ICPInductively Coupled Plasma
MADMixed acid digest including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids. This extended digest approaches a total digest for many elements however some refractory minerals are not completely attacked
MoChemical symbol for molybdenum
MSMass Spectrometry
OESOptical Emission Spectrometry
ppbParts per billion, e.g. 1000 ppb Au equals 1 ppm Au, or 1 g/t Au
ppmParts per million, equivalent to g/t
RAB DrillingRotary Air Blast drilling. A drilling method in which the sample is brought to the surface outside of the drill rods using compressed air.
RC DrillingReverse Circulation drilling. A drilling method in which the sample is brought to the surface inside the drill rods using compressed air, reducing contamination.
ReChemical symbol for Rhenium
RheniumRhenium is a rare metal that is highly resistant to heat and wear. Rhenium resembles manganese chemically and is obtained as a by-product of molybdenum and copper ore
XRFX-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for chemical analysis
