REVERSE CIRCULATION DRILLING
 

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 is also faster than coring which means more holes drilled.
