I suspect that gold is a very common metal throughout the inner solar system, and the asteroid belt. It’s only valuable now, because of its rarity on earth.

But once we can mine the lower gravity of Mars, then someone might dig up a gold mine.

And Venus I would suspect has a lot of gold. If we can slow it’s runaway global warming, then we might be able to establish a colony there, and mine gold.

The same concept goes for Mercury.

I’m surprised that the Moon hasn’t revealed trace elements of gold yet. I suspect that it might be buried deep inside the core, where it sunk, while the moon was still molten and forming. If someone can find a gold mine deposit there, then they can build a mass driver to launch it on a return trip back to earth. Or just use it to build new spacecraft in outer space.
