Our Values

IDC delivers the following high performance and tailored drilling services :

Rotary Air Blast (RAB)/Air Core (AC) is the simplest and most economical technique for the first step of exploration. It enables to have a good idea of site mineral potential

Reserve Circulation (RC) is the second step of exploration. It achieves better penetration and sampling than RAB or air core drilling but is slower and costlier Diamond Drilling (DDH) is the third and costliest step of the exploration process. The core samples are examined by geologists for mineral percentages and stratigraphic contact points in order to give exploration companies the information necessary to begin or abandon mining operations in a particular area
