Sakdrisi-Kachagiani is a hill in southeastern Georgia, in Bolnisi municipality, near the townlet of Kazreti, 20 km from Bolnisi. The first scholarly work on the hill was carried out in the 1980s under T. Mujiri; in the reports of that period the idea first appeared that prehistoric workings might exist here. In 2004 initial archaeological research began on the Sakdrisi-Kachagiani hill, and from 2007 to 2013 a Georgian-German archaeological expedition led by Thomas Stöllner and Irina Gambashidze carried out investigations. They maintain that the site is a prehistoric gold mine (3350–2500 BC). In scholarly circles, however, there is also a different view, with some scientists categorically ruling out the existence of a prehistoric gold mine at this site.
