Up to this point I estimated there to be around 160,000 tons of gold above ground and I think that's along the lines of other estimates.
Karen says that there is at least 500,000 tons of gold, all conventional figures say about 160,000 tons. The latter figure is imho rather well researched from the mining output in 20th century - before which only a fraction of the total gold existing was produced. Do you have some credible theory, how the gold aboveground could be so much higher figure?
