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.
