I'm catching up on my reading again.

Drillers are the people who operate the drills which find the target. A drill rig is run by a small crew. They have 2 rigs so they have 2 drill crews. When they get more drills of course they will hire more employees or drillers. You know that NOT has purchased some new ones that are being assembled now. The drillers will set up where the geos tell them. You know, drill here!.....and if they are lucky or know their business they hit or strike a lode or vein. I hope that helps..Don
