Diamond drilling is much slower than reverse circulation (RC) drilling due to the hardness of the ground being drilled. Drilling of 1200 to 1800 meters is common, and at these depths, the ground is mainly hard rock. Diamond drilling rigs need to drill slowly to extend the life of drill bits and rods, which are very expensive.
