I Went Mining For 12 Hours & Made $____? Jul 6, 2024 Join me as I spend 12 hours mining inside Cerro Gordo's Union Mine! The miners back in the day would get paid $3/day for an above ground shift and $4 a day for an underground shift. A day would be a 12 hour shift. So in this video, I'm going to do the same amount of time down in the mine, and see how I do! https://www.youtube.com/watch?v=rSdj2jJY4p4
