If you add up all those numbers you just gave besides the gold in the ground one, they add to exactly 187200. So no that is not gold in the ground. That is the estimated gold existing that has been mined. You may be reading the articles but not getting the right thing from them. Also gold in the ground does not count as being in the market because well it is still not mined, it is just known to exist.

Also you omitted the direct quote "Total above ground stocks: 187,200 tonnes" from the site you posted. So no that does not include gold that has not been mined.
