"Gold is the only metal that doesn't rust, even if it's buried in the ground for thousands of years."

Utter nonsense.
Only iron rusts.
Neither gold, nor platinum, nor palladium, corrode.

Thanks for the audit - I found this too - thread might turn out to be educational;)

Stainless steel, gold, silver, platinum and aluminum (after forming a barrier from minimal exposure) are all rust-proof metals. Rust is the process of iron oxidization, so it specifically refers to the iron content in a metal.

Only iron rusts.
