Reverse Circulation

To accomplish drilling project objectives within budget, Reverse Circulation drilling offers a more cost effective drilling method for assaying chip samples and getting preliminary geological data prior to investing in detailed geological data from an exploration coring program. Reverse Circulation drilling is primarily used for exploration and grade control and can penetrate hard rock to depths of around 500 metres. Reverse circulation is also faster than coring which means more holes drilled.

DDH1 offers Reverse Circulation capabilities through our multi-purpose specialist rigs. We generally offer this service as a pathway to full Diamond Coring drilling. Our partner companies, Ranger Drilling and Strike Drilling, also provide specialist Reverse Circulation drilling services across the commodity chain.
