Slightly misleading title though. It's not actually making gold, the high pressure (as I understand it) is vaporising all the other minerals which leaves behind the already created gold, but in a nice tidy vein.

yeah, I'm pretty sure you need nuclear fusion to create gold.
In nature, this would be an exploding star, super nova.
Simple h2o and an earthquake could'nt do it, you need to smash those atoms together with much more energy.

Nuclear Fusion? Are you sure? Is that how the gold was created? Really? Exploding stars and super nova's? AHHA There are microbes that turn other elements to gold. Also there was enough energy to vaporize water! Maybe there was enough energy to help do the gold...edit on 18-3-2013 by DaRAGE because: (no reason given)

Yes, you need fusion. No, microbes do not produce gold from other elements, as they cannot fuse nuclei. And as said, it doesn't even happen in most stars lives, they need to be big enough to go supernova at their death.
Scientists say they have discovered how a bacteria turns water-soluble gold into microscopic nuggets of solid gold. The bacteria Delftia acidovorans is frequently found on the surface of tiny gold nuggets. Its presence led scientists to speculate it may be creating the particles from soluble gold - ions of gold that are dissolved in water. But the puzzle was how D. acidovorans did this trick, as soluble gold is toxic. The answer, suggests researchers from Canada, lies in a molecule excreted by the microbe that both shields the organism and transforms the poisonous ions into particles. "This finding is the first demonstration that a secreted metabolite can protect against toxic gold and cause gold biomineralisation," the process by which living organisms produce minerals, they write in the journal Nature Chemical Biology. The molecule, delftibactin A, is capable of achieving this feat within seconds in pH-neutral conditions at room temperature.
The gold you see in the photo above was not found in a river or a mine. It was produced by a bacteria that, according to researchers at Michigan State University, can survive in extreme toxic environments and create 24-karat gold nuggets. Pure gold.
They are the ones who have created a compact laboratory that uses the bacteria Cupriavidus metallidurans to turn gold chloride — a toxic chemical liquid you can find in nature — into 99.9 per cent pure gold.
