CDHD are specialists in all aspects of Underground and Surface Diamond core drilling, including directional drilling that allows for controlled deviations in the direction, angle and path of the drilling activity required.

In addition to directional drilling, CDHD also has the technical ability to conduct multiple intersectional directional drilling which typically involves the drilling of a main “parent” hole (up to 800m in depth) followed by multiple “branch” holes which come off the “parent” hole (to depths of up to 1,200m)

This increases the accuracy of the geological information gathered to facilitate development or expansion of mine production. 

Drilling branch holes from a main hole significantly reduces the length of a drilling program, leading to savings in both time and costs.
