Air-core drilling is relatively inexpensive and is often used in first pass exploration drill programs. Air-core drills 75mm to optimal depths 75 metres and is performed using a smaller mobile rig known as an Air-core rig.

It uses steel or tungsten blades to bore a hole into unconsolidated ground. The drill cuttings are removed by the injection of compressed air into the hole. 

Advantages of Air-core drilling 

  • It eliminates the need for casting holes.
  • It provides a more representative sample of material.
  • Less chance of cross-contamination.
  • Delivers safer sample removal.
  • Boosts efficiencies and reduces costs.
