Prior to diamond drilling, mining was still primarily dependent on finding outcrops of rock, with little information about ore concentrations below the surface. Diamond drilling allows the removal of solid cylinders of rock (core) from deep within the earth.
The advantage of RC drilling is that it produces large quantities of high quality, reliable samples free of cross-contamination, so that mineral deposits can be located more precisely. It is slower, but achieves better penetration than other types of drilling.
Rotary mud drilling is a popular and dependable extraction method. The weight, viscosity and filtration control of the mud during the drilling process keeps particles from floating around and cools the drill bit as it bores deep underground.
