It is one of the major mines (locally called canope) that are part of the old Monte Calisio silver-mining complex.
Position and structure
The mine is situated at about 600 m asl and is located about 1 km from the village of Gardolo di Mezzo, near both to Masi Saracini and to Via Claudia Augusta .
The mine has three entrances: the lower entrance and the main entrance are connected and continue with a remarkable development of tunnels which are often unstable and passable with difficulty. The third entrance, unlike the previous ones, does not continue in depth but stops almost immediately.
