The graves of the necropolis were built between 4700 and 4200 BC, showing that gold mining could be a minimum of 7000 years old. A group of Georgian and german excavators declares the Sakdrisi website in southerly Georgia, dating to the 3rd or 4th millennium BC, might be the world's oldest known gold mine.
