Reverse circulation drilling helps mineral exploration industry to economically collect
samples when searching for ore bodies. Reverse circulation method is used mostly in
tough, broken and abrasive formations and offers several economic advantages over diamond
coring in these environments as well.


Underground RC drilling operations uses Matrix M3.25 RC Drill Rod.
Surface exploration applications uses Matrix M4-4.5"-5.5"-6" RC Drill Rod.
Larger diameter RC drill rods include 7"-9-5/8"-10.75" for bulk sampling,
mine dewatering and water resource applications.
