RAB

rab drilling methodThis is an older exploration drilling method no longer commonly used. Sample quality is less accurate than Air Core due to the use of a single tube. This means that samples have the risk of contamination through contact with the geology of the drill hole. This is because the sample recovery is outside the drill-string. Air Core drilling is different as the sample is isolated from the geology of the drill hole by the sample tube.
