Alpine clefts, with excellent finds in the 1970s. Located 3 km W of Deutschlandsberg at N46.80982 E15.18923.

Recently, a new adit was driven by the Hofer brothers (mineral dealers in Salzburg) and excellent greenish titanite crystals up to ~11 cm were found in 2016. The mineralogical study of the new finds will be carried out at the Joanneum in Graz as the official partner.
