RC DTH Bit RC 545 Hammers High Quality RC Bit RC samples are collected at the drill and sent directly to the assay lab. Unlike diamond drill core, which is generally logged, photographed, split for sample, assayed and warehoused, RC sampling requires much less handling resulting in faster assay turnaround with accompanying cost reductions. Larger volume RC samples often give more representative gold samples than split half core samples.

(1) RC drilling uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.(2) RC drilling utilizes much larger rigs and machinery and depths of up t
