RC Drilling (Reverse Circulation)

RC Drilling is the most popular method of drilling in the mineral exploration industry as it achieves a better penetration than RAB or Aircore drilling.  The drilling mechanism is a pneumatic reciprocating piston known as a hammer that drives a tungsten-steel drill bit.
