There are several large high grade copper deposits that are easier to get at here is the US.
But the insane enviro wakos and the anti mining crowd have stop there development.
Plenty of high grade copper around after the collapse. No need to go through the pain of refining it.

7000 feet? 175 degrees?
But Al The Goron said it was millions of degrees down there.
I have heard that landfills contain metals at concentrations the same as mines.
I’m not so sure of that; some mining activity stopped not because of availability but because costs were lower and/or quality was higher elsewhere. The iron mining along the NY/NJ border stopped for that reason; plenty of iron still there. In fact, during WWII they refurbished some of the mines that had been closed for decades in case they needed more iron, but the war ended and they left them as is.
I’m surprised that this effort is in the US given the envir opposition to any thing mining. As another poster commented, there are still high grade deposits near the surface but envir opposition prevents mining. Even this underground effort is goint to take years to permit. And mining at Superior (located east of Phoenix) has been underway for over 140 years.
Interesting how the temperature with depth increases differently around the world…. … the TauTona Mine (Western Deep No.3 Shaft) in South Africa is currently the deepest mine at just a bit under 13,000 feet and its temperature is only about 140 degrees F.
The copper mines in the Kewenaw peninsula in the UP Michigan owned by the Calumet Helka mining company went 12,000 down at an angle I believe.
And that was almost 100 years ago.
“The main reason is the survivors will not be able to get to metals like cooper as all the easy access deposits the fueled the Bronze Age, a mixture of cooper and tin, have been depleted.”
This is an interesting thought that had not occurred to me. I would think though, that there would be enough scrap laying around to get us going again.
They could simply mine the garbage dumps.
If civilization collapsed, there would be 50%- 90% fewer inhabitants of the Earth within one year.
It is estimated that around 90% of the U.S. population would die within one year of an electromagnetic pulse event. We are so dependent on modern society and technologies that most of us would die very quickly.
I disagree with Derbyshire. The recovery would be surprisingly quick.
The amount of technology distributed to the populace is absolutely amazing and it would be put into play immediately.
The populace would be much smaller.
Nearly all of those previously mined deposits are readily available through SALVAGE. I could find all the copper I need to make my short sword just by stripping electrical wiring.
The Resolution project is located on what was called the mill fault and below the old Magma Mine where I worked and the Town of Superior Arizona where I grew up. My dad worked there beginning in the early 1940s after the goldmines were closed due to WWII. He had quite a career there and at San Manuel Mine (also a Magma/Newmont Mine where I worked for much of my career).
I worked at Magma / Superior for a couple years before going to work at San Manuel after I got out of the service. The Superior mine was a hot and dangerous mine, taking a couple of lives every year.
Malarkey. The "per human" amount of available resources will skyrocket and be nicely collected in urban concentrations, much of it in already-pure or nearly so condition. Guy obviously has not read much science-fiction.
Mostly they were separated by long distances.
IIRC there was only one place where there was a copper tin mix, either in Iran or Iraq and that was where bronze was discovered.
After that they were mined separately. Tin was mined around the Black Sea and in England. Copper was mined all over the place as copper is fairly common.
That makes no sense. The copper would still exist...and it may be easier to get to because it’s already been processed and just sitting there.
Melt down what is above ground as there are miles and miles of copper and aluminum in all the buildings and outside on the poles.
People “mine” circuit boards for precious metals as it is easier then digging for it.
The environmental wackos would have been killed off so it would be easy to mine new sources as well.
