Name(s) in local language(s): Miniera di amianto di Poggio San Vittore, Balangero/Corio, Valli di Lanzo, Massiccio di Lanzo, Torino, Piemonte, Italia
 
Big abandoned (1990) asbestos mine on the municipal territories of Balangero and Corio, 30 km N of Turin, in a satellite body of the Lanzo ultramafic massif. Mineral collecting is now forbidden.

The Balangero serpentinite body (~7 km2) is a satellite of the Lanzo ultramafic massif also in tectonic contact with the Sesia-Lanzo Zone and at present level of exposure is separated from the Lanzo Massif by a band of Quaternary terrains several kilometres wide. It manly consists of antigorite serpentinite with relics of the original mantle peridotite. In the Balangero serpentinite body operated the famous Poggio San Vittore asbestos mine, which is the type locality for balangeroite.
