Gold is a finite material, one of the rarest on earth, in fact. Humans have been digging the stuff out of the earth for more than 5,000 years now, and, with exceptions, it’s likely we’ve exhausted the supply of “low-hanging fruit.” Mining it, then, requires that we dig deeper, and in more remote or inaccessible places, meaning it’s gotten a lot more expensive.
There will come a day, perhaps sooner than we think, when it’s no longer economically feasible to develop new deposits, especially those that are not expected to yield a whole lot.
