Butte? Anaconda? Tooele? Columbia Falls? Twin Buttes? Thunder Basin? Yerington? Chuquicamata? El Salvador? Miami? Darwin? Cananea?
Holy crap - knowing about Chiquicamata, and spelling it correctly? Only reason I know is that my grandfather worked there, and my mother was born in Antofogasta.
I'm about 250mi away in Idaho but remember going to Anaconda Montana and the Berkley pit in Butte as a kid and watching the operations there but I'm too young to have worked there.
