RC Grade Control Drilling

At Inline Drilling Ltd we provide Reverse Circulation (RC) Drilling services for Open Cut Grade Control drilling and we also offer Exploration type RC services nationwide.

Open Pit RC Drilling

Open Pit Reverse Circulation Drilling (RC) is a specialised Drilling Technique were the drilled aggregate travels up through the centre of the drilling string and into a "splitter" box where samples can be collected and passed onto the Laboratory for further assessment.
The laboratory then creates a three dimensional model of the deposit and the ore boundaries are highlighted to the excavation team who extract the material for milling before being poured into "Dore" bars, a mix of Silver & Gold. 

Our latest RC Rig is capable of drilling vertically, horizontally or inclined. The unit can also drill angled RC holes within four metres of any highwalls. The new cone splitter offers a three level split and also the options to pre select sample bag volumes and one or two bags from each sample.
