A large quarry exploring pegmatites, gneisses and micaschists. Numerous minerals are reported both from the pegmatites and mineralized clefts in the surrounding rocks. The quarry was first worked by the Gall company and later, by the Modre company. Intermittently abandoned, it is now worked again since 2001.
Located in the Fraßgraben, near the road leading from St Gertraud (northeast of Wolfsberg) to the Weinebene.
