They have some good videos on their mining technique at:

It can't begin to compare with the shaft we are being given by both the political parties in concert with a Marxist president. JMHO!
When I was at Superior, stope mining was the time tested technique. However, over half of my career was spent at San Manuel, also part of Magma Copper at that time. Block caving was the mining method used there until the oxide ore was leached in the subsidence zone. It was kind of weird looking down at the foundations of homes I’d visited and played at in Red Hill slipping lower and lower in the cave zone. Resolution, like San Manuel did, is going after the porphyry deposit.
fascinating. great pot.
i wonder how the cooling is done? do the miners wear special suits or is the entire mine cooled? and what about the equip? operating at 180 degrees?
