The Feds are still holding this project up. It would be a very significant number of jobs and rescue for the disintegrating town of Superior. I was born and worked there in the old portion of the mine. Emotionally I'd sure like to see this go ahead. The rock and, of course, water temperature at the 6900 level is 189 degrees F. The older mine where my Dad worked some 40 years was hot at 145 F. The older mine pioneered cooling and ventilation technology in underground mining beginning around 1907.

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!

I was thinking of deep oil wells, but yours is even bigger!

Imagine an economy where the FedGov didn’t impede everything it touched. How in Gods green earth could operations a mile underground disturb anybody?

If I had a dollar for every time I spoke those exact words......the feds would tax me into poverty.
In all seriousness, congress should have no say over projects entirely within a state's borders. Approval or disapproval of the keystone pipeline should be entirely up to the states it would cross. Directional drilling under the great lakes should be up to the states bordering the lakes (Canada already drills under the lakes)

Will Obama condemn this polluting exploitation of America’s underground treasures, take credit for this American accomplishment under his watch, or say “You didn’t build that.”

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.

Feds are also holding up nuclear waste isolation in Nevada, as long as Harry Reid is their senator.
Instead, spent fuel sits in unsafe swimming pool storage at plants around the country. Unsafe as in Japanese nuclear plant unsafe. Fuel storage is as much a risk as the reactor containment.

Actually, the block caving operation will cause a subsidence zone at the surface. They will be caving the ore body down into haulage levels and taking the ore from the bottom.

—interesting—unless hoist cable spec’s have changed , that depth with single lift is getting close to the limit of a safety factor of 6, IIRC——

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?

Yeah, a single lift surprised me. The original mine had numerous sub levels and, by chasing the high grade veins, looked like a rabbits warren. The old and new mines have a lot of big differences. The source of the copper was in the porphyry deposit but the high grade was in hydrothermal veins. Bornite was a common ore and, at 65% was directly smelted after bringing the grade down actually.

Several years ago, when I was in Phoenix for Spring training, I recall a fascinating article in the Arizona
Republic about a planned copper mine that a.) would mine an ore body located below an existing ore body and b.) was so deep, it would have to be operated by robots.
Is this the mine they were writing about?
