THEY DO HAVE TENS OF BILLIONS !!!
Says who?
If you take the length of the core and multiply it by the average gold assay, then divide by the age of the geriatric geologists, and take it to the power of the temperature of the plasmafication, and then move the decimal point the number of years this scam has been running, you might have tens of billions. Or something like that.
I saw this method in a technical paper issued by a S. American placer mining scam, so it must be industry standard.
