When was it determined that there were 4,000,000 tons of gold bearing ore yielding 2.5 to 16 grams per ton ?
The Great Oracle from Nevada declared it. Then the Great Accumulator blessed the notion it became so. Besides you don't really need to process and sell 4,000,000 tons of gold or even show that gold exist. It's just something you have on paper so you can pretend to claim gold sales are being reported via the test miner exemption rule and expense things against the "value" of the property claim.
The reason they haven't dug into this cornucopia of treasure is becasue they are still working on the amazin' rich shaft that has visible gold. Nevermind that the only way to access the shaft is by a ladder or modified cherry picker, just trust the Great Oracle and Great Accumulator that it is there. .... along with the gold nuggets lying around that can be picked up by bare hand.
The method used to determine there was 4,000,000 tons is the WAG method. First you make the assumption that becasue a neighbor had a vein of gold running through thier property that must mean there are veins of gold in mine too. Then you make a Wild Ass Guess about how much is on your propoerty based on how much mineral deposit your neighbor claims to have.
