An RC drilling program is faster and more cost effective than diamond coring. However, it’s the quality of the samples that is the most important consideration.
 
  
Geologists must have confidence in the accuracy of the sample and way that up against the time and cost involved. When that is done it’s easy to see why RC Drilling with its recent technical advances has become the preferred drilling method for exploration and in-pit grade control.
