A brief introduction to how diamond drill rigs drill and extract core for testing mineral deposits. Many thanks to Ravenswood Gold for allowing me the time to shoot the footage and to Eagle Drilling for access to their rig. Special mentions also to Rob the driller, Jacob the offsider and Sam the geologist for doing such a fine job in front of the camera completely unscripted.
