Nothing is known about him except that he appears to have hit the Jackpot and then Slain by Mr Natas (Satan). His face is not visible and his look in the randomly made transmissions is like a static from a TV.
This miner has a little bit of information about himself. He appears to be wearing a Orange suit with a mining helmet. He also has a huge worrisone like feelings at you sometimes. He would pop up on random transmissions like the other guy, but rather complaining about his issues and gives you a tip, later on when you are at around 4,000 feet deep or near that, he will also reveal that he has two kids and a wife before getting killed.
