This is a figure difficult to ascertain with absolute certainty. Limiting factors include, the rudimentary technologies and mining techniques of ancient civilisations being one of the factors, Gold reserves aren’t exactly something that governments necessarily disclose to other nations freely either, which makes it difficult to put an exact number of the amount of gold mined throughout human history. However, a figure that is widely used by investors comes from Thomson Reuters GFMS, which produces an annual gold survey, estimating that number to be in the vicinity of 171,300 tonnes.
