In the exhibition mine in Prettau (Predoi), 15 km. (9 miles) away from Kornkasten (Cadipietra) there is an exhibition mine with over twenty tunnels and shafts through ore deposits at an elevation of 1,400 to 2,100 m. (4,600 to 6.900 ft.) The visit includes a ride on the mining rail in the St. Ignaz shaft (1.1 km. / 3/4 mi.) from which cement copper is still extracted. In 2001, an asthma therapy station was also set up in this mine.
