> If we observe the share of trace elements in the gold from Troy, Poliochni and Ur, Bronze Age gold from Georgia correlates the closest with the stated find sites. But we still lack data and studies from other regions...

The Sakdrissi gold mine in Georgia was discovered in 2004 by German archaeologists from Ruhr-University Bochum and is dated to the third millennium BCE.

The region south of the Great Caucasus (present day Georgia) is known from the Greek myth of the “Golden Fleece”. Iason, a Mycenaean hero of royal origin, sailed with the Argonauts from Greece to the Colchis to demand the “Golden Fleece” from king Aietes. Iason successfully looted the fleece with the help of the king’s daughter, Medea. The “Golden Fleece” stands as a symbol for the recovery of gold from placers using the skin of an ox or a sheep. The myth of the “Golden Fleece” is proof of the economic wealth of this region. The richness in gold is verified extraordinarily by the excavations of 5th to 3rd century BC royal graves of the acropolis at Vani, the capital of the kingdom of Colchis.

A few contenders:

The oldest processed gold in the world was found in Bulgaria, 4,560-4,450 BC on the Bulgarian Black Sea coast.

Nubian gold mines may have first existed from 5000 BC.
