Reverse circulation (RC) drilling represents a fast and economical way to retrieve the high-quality mineral grade samples needed to efficiently plan your mining and quarrying operations. The RC drilling method not only prevents cross contamination, but also enables collection of a large number of sample bags in a short amount of time. Sample bags are labelled with the same location and depth information. Further analysis yields fast, reliable information about mineral deposits that allows you to selectively pinpoint zones for drilling and blasting for maximum ore recovery and greater profit per...
