The site of a Late Vinca copper mine, in the limestone hills of northeastern Serbia. The mine, dated to the early 4th millennium BC, employed a mining technique involving the construction of platforms on the steep hillside and follow the vertical veins of malachite down, thereby creating empty 'shafts'. Sealed deposits of miners' lamps, antler picks, and gabbro mauls have been found at the bottom of abandoned mineshafts, of which there are over 25.
