World´s oldest underground hard-rock gold mine, worked since the 3rd millenium B.C. A set of seven 14C data carried out so far revealed mining activities spanning the period from the second half of the 4th to the middle of the 3rd millennium BC

Finely disseminated gold in steeply dipping veins cutting silicified pyroclastics was worked already more than 4,000 years ago down to depths of 20 meters.

The gold found here is noted for its high purity.
