When you look at the crew job ads for “underground”, you will see that none of the employers want RII tickets or formal qualifications. They want a manual car license, be able to pass a medical including a drug and alcohol test, a police clearance and experience. The experience the employers want out of someone with 6 months time in the job, is to know how the mine works and what is going to be expect of them on site. Teaching someone to drive the truck is the easy bit, teaching them how the mine works so you can leave them alone, to get on with the job, is the hard part. When you can show the employers you know how their mine works, then you have something to offer them.
