The Carey Drilling Division specializes in all aspects of underground drilling using In-The-Hole (ITH) Technology.  Our expertise ranges from standard blast hole drilling, Reverse Circulation Grade Control drilling to V30 raise boring. This work can often be achieved using the same equipment which means less mobilisation costs and greater mining flexibility.  Our state-of-the-art Sandvik fully electric fleet, with over 14 rigs, aligns with Carey’s net-zero transition pathway.
As Australia’s leader in ITH reverse circulation (RC) Grade Control drilling, our wholly owned subsidiary, Metres Down Under, has proven the value of this method over the past 10 years, surpassing 2 million meters of underground RC grade control drilled at AngloGold Ashanti’s Sunrise Dam Gold Mine.  Underground RC is cheaper and faster than diamond drilling, producing high quality samples, often more representative of the mineralization than diamond core.
