WHAT IS RC GRADE CONTROL DRILLING?

Grade control is an integral part of the mining process.  Drilled at relatively shallow depths and with tighter patterns, Reverse Circulation (RC) grade control drilling defines the ore body prior to mining and confirms the grade of the ore when mining has commenced.

Operating a fleet of Atlas Copco L8 and D65 rigs, Rock on Ground (ROG) have the knowledge and support to provide both in-pit and remote grade control drilling services.  ROG’s team of experienced personnel understand the importance of delivering quality samples during the grade control process.

Track mounted grade control drills are more compact than traditional rubber-tyred reverse circulation grade control drills. Requiring less pad preparation work and having a smaller footprint, they are better suited for contours and uneven ground. Greater mobility provides reduced set-up time over each drill hole, and the mechanised rod handler and carousel ensure grade control drilling time is maximised.

We provide dedicated equipment specific to each job’s requirements, that is backed by a team of experienced operators, maintenance support and management committed to providing quality grade control services to our valued clients.
