Though mine owners raked in the cash and lived comfortably, it was a different story for the workers. "At Sterling, miners got paid by how much ore was taken out," explains Bayne. Once they ventured into the mines to excavate the magnetite, they would light black powder or dynamite and "run like hell," says Bayne.
