The on-board compressor delivers power to a pneumatic reciprocating piston. The piston, in turn, drives a tungsten-steel drill bit which is purpose designed to be able to crush hard rock.
Similar to air core drilling, drill cuttings are returned to surface inside rods. We achieve this through the use of dual wall drill rods: an outer drill rod with an inner tube. When compressed air is blown through the rod, the volume displaces the air, lifting the samples to the surface.
Once cuttings reach a diverter at the top of the hole, they’re moved through a hose and around the cyclone, which slows the sample down. From the cyclone the sample goes over a splitter that delivers a percentage of the entire sample into a sample bag. The exploration drilling team then collect the samples aligned to the hole depth and lay them out for the client to log, and then transport to the lab for assay.

Product Features
Versatile across terrains
When compared with diamond drilling, Reverse Circulation drilling uses far less water, making it ideal for remote areas of WA, where sourcing water can drive up the running costs of an operation. Compound this with an average 40% lower operational cost, and it’s a reliable choice for complex and remote locations.
Reliable samples
One benefit of RC drilling is in keeping samples free of cross-contamination. Because the cuttings travel through the inner tube, they aren’t exposed to other areas of the hole. Furthermore, samples are labelled relating to depth and location.
Workforce and time savings
Cover more ground in a day. Combining a rapid method of retrieval of drill cuttings and superior production rates than diamond core drilling, means you get results from RC drilling faster. RC drilling also has a small rig footprint, eliminating the need for extensive earthworks.
