I'd always suspected Fool's Gold was up to something.
“The discovery rate of new gold deposits is in decline worldwide with the quality of ore degrading, parallel to the value of precious metal increasing,” Dr. Fougerouse said.
Of course, more than half of the gold ever mined in history has been since the late 1950s, and if put into a single cube, would be about 70 feet on a side (the estimate varies). Within a human lifetime it's likely that a single asteroid doubling the known amount of mineable gold will be discovered, and probably more than one.
