Operating in Guinea since 2001


SBDG began operations in Guinea in 2001 under an 18-month contract to drill the fabled Simandou iron ore resource. Since those early days, the business has expanded to conduct further drilling and mechanical services at Simandou as well as other iron ore and gold prospects within Guinea and surrounding countries. In all, SBDG has been involved in RC drilling in West Africa for two decades completing in excess of 350,000m of exploration and grade control drilling.


SBD Drilling owns and operates a fleet of technologically advanced, environmentally friendly Atlas Copco Explorac 220 RC rigs as well as the associated auxiliary equipment. Currently two of these rigs are located in Guinea. We specialise in deep hole reverse circulation (RC) drilling with capabilities of 400+m depth. The rigs are track mounted and equipped with noise suppression canopies, automated rod handling systems, fire suppression, on board sampling units and working at heights safety systems.

We utilise Atlas Copco auxiliary compressors and Hurricane boosters with a combined output of 2200 cfm @ 1000 psi enabling our rigs to reach target depths with high-quality dry samples. The smaller size of SBDG’s Explorac rigs means a smaller pad size than the equivalent Schramm or KWL RC rigs, resulting in less environmental impact whilst still having the air to drill the holes successfully. The rigs are very fuel efficient compared to competitors rigs with the same capability and a smaller footprint for drill pads.

SBDG employs highly credentialed drillers and fitters that are experienced in deep hole RC drilling. All of our senior employees have a strong safety culture that complements SBDG’s safety procedures and systems. This enables SBDG to complete drilling campaigns on time, within budget, while meeting our goal of zero harm to our people and minimal environmental impact. We have regularly operated through the wet season in West Africa and have no issues with steep access tracks.
