Both the tunnel and the cable car (about 2 km in length), open on March 29th, 1909. The cable car is located in front of the excavation on the other side of the stream, on the orographic left, which allowed the connection with the Valpelline foundries.
It runs for 2.5 km and is connected to the cultivation tunnels of the Saint-Jean section in Ollomont at the height of level called Santa Barbara. It performs the function of unloading the material: from here a cable car transports the extracted mineral to the foundries in Valpelline, downstream from the village on the orographic left, for initial pro- cessing.
Subsequently, the material is transported to Quart to provide for the subsequent processing and distribution.
Near the tunnel there are also some buildings that house a warehouse, a workshop, a munitions depot, housing for workers and a room for pu- mping water.
It is currently used as a storage warehouse for Fontina.
