It almost needs to be melted in the ground and pumped out.
“It almost needs to be melted in the ground and pumped out.”
It still comes down to hard rock mining, and the UP has some of the best. But the people who worked at Calumet & Hecla when it shut down in 1968 are getting old now, but they have knowledge they can pass onto young people.
I would love to see hard-rock copper mining back on the Keweenaw.
That’s a great idea!
Not ‘melted’, but dissolved!
Acid, or some other chemical of a sort that could dissolve the copper, liquify it and just pump it out like oil!..........
