Diamond Core Drilling

Diamond core drilling is the most accurate style of exploration drilling. This method produces a solid cylindrical core of solid rock that is extracted for examination. Core sampling provides the most accurate assessment of the deposit.

The core sample may be split longitudinally using a core splitter if required and half sent for assay while the other half may be stored for re-assaying in the future.

This drilling uses a diamond encrusted drill bit to drill through the rock. Water delivered to the cutting face to lubricate and cool. The diamond drill bits are designed for specific rock types and different rock formations require different matrix drill bits.

Diamond core drilling can be carried out in various sizes depending on the required size of the core sample.
