Characteristics of RC Pipes:
■ Use of dual wall drill rods: an outer tube with an hollow inner tube
■ Inner tube enables to transport drill cuttings back to the surface
■ Uncontaminated samples and lower handling times
■ RC pipes allow continuous and homogeneous operation
■ Faster drilling performances at greater depths
■ Most cost and time efficienct method to differentiate between minerals and waste rock
