The new Pruten spring has a capacity up to and by 2011 a waterworks was constructed which supplies the villages of Babe, Stojnik and Ropočevo, so as the complex itself, with the water from this spring. Moreover, during the excavation, a hidden entry into the vast complex of Roman mines was discovered, too, being obscured for centuries. There are evidence of the extraction of
silver,
iron and
lead. In the 3rd century AD, the Kosmaj mines were one of the most important in the Roman Empire, and were administered by the Roman procurator Babenius, whose name is preserved in the name of the Babe village. In the 1970s and 1980s, experts from the
National Museum in Belgrade explored the area and discovered many mining necropolis, centered around the villages of Babe, Stojnik and Guberevac. It is estimated that there are some 100 ancient mining shafts on Kosmaj, which go below the ground and are wide. After the Roman period, mining activities ceased, only being revived in the
Medieval Serbia. == Characteristics ==
