What this place is
Escondida sits 3,100 m up in the driest desert on Earth and pumps desalinated seawater 180 km uphill to run its concentrators. It is the single clearest example of what modern copper costs: enormous scale, falling grade, and infrastructure that dwarfs the mine itself.
What comes out
Copper
The reddish metal that carries electricity better than anything except silver, and which humans have been smelting…
Gold
The metal that does not tarnish, does not corrode and never runs out once mined — which is why almost all of it ever…
Molybdenum
A silvery metal added to steel so it keeps its strength at high temperature and under pressure.
Silver
The best electrical conductor there is, and the metal that has been used as money for longer than almost anything…
A “by-product” is a metal recovered because it happens to be in the same rock, not because anyone went looking for it. Its supply therefore follows the primary metal’s economics, not its own.
Who owns it
As publicly reported by the operators. Ownership of large mines changes; verify against current company filings before relying on it.
