  • AirCore Drilling

    Aircore uses steel or tungsten blades to bore a hole into unconsolidated ground. The drill cuttings are removed by the injection of compressed air into the hole. This method of drilling is used to drill the weathered regolith (loose heterogeneous material covering solid rock) as the drill rig and steel or tungsten blades cannot...

  • RC DrillingWhat is RC Drilling? RC Drilling

    RC drilling ideally produces dry rock chips as large air compressors dry the rock out ahead of the advancing drill bit. RC drilling is slower and costlier but achieves better penetration than RAB or air core drilling it is cheaper than diamond coring and is thus preferred for most mineral exploration work.

    RC drilling is similar to air core drilling in that the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungstensteel drill bit. RC drilling utilises much larger rigs and machinery and depths of up to 500 metres are routinely achieved.
