Once you start the drill you don't stop it...and you pay ,weather it is turning or not/...
Try plugging in 24/7...
And these dudes are not slinging big Mac's..and getting slave wages..
These are top $$$$ guys,and doubt if any driller gets under $100k a year..that is not the geo..that is the drill crew..

My brother was running a diamond drill in the maritimes in the 60's and was making 60-70 K a year..
