Reverse Circulation (RC) Drilling
Reverse circulation (RC) drilling is the workhorse of mineral exploration and grade control: fast, cost-effective, and built around clean chip samples. Our PRD OZ RC is in our fleet and available to rent now.

How it works
RC uses dual-wall drill rods. Compressed air travels down between the two walls to the hammer and bit, then returns up the inner tube carrying the rock chips to surface, where a cyclone collects them. Because samples travel inside the rod rather than up the open hole, contamination from the hole wall is kept low.
Used for
- Mineral exploration and resource definition
- Grade control ahead of mining
- Inclined holes from 45° to 90°
- Programmes where speed and cost per metre matter
