Unless it's the cave of Yamamoto's fabled gold stash - I don't think that's quite right Mr Kodal. Think of it like 4-5 metric tonnes of ore might give you a Troy Ounce or 31 grams. Or 150 tonnes might yield a Kg of Au. 150,000 tonnes for a metric tonne of Gold (32000 ounces). All based on a presumption of 7-8g/t and high recovery.

I reckon ***ong could have produced anywhere between 5-10 million ounces. It's probably got the same amount left to extract - but it generally gets more difficult to do so. Just my opinion.
