(Grube Arme Hilfe, Ullersreuth, Hirschberg, Vogtland, Thüringen, Deutschland)
Ancient iron and copper Mine, closed in 1899.
Located 3 km N of Hirschberg.
Note: Ullersreuth is not in Saxony (as given in many references).
Note on the "liroconite" reported in the old literature:
It was originally reported by Breithaupt, A. (1841): Vollständiges Handbuch der Mineralogie, Bd. 2, Dresden und Leipzig, p. 158, who later, however, noted that this was a wrong identification and that the sample was in fact "Tagilite" (= Pseudomalachite): Breithaupt, A. (1865): Mineralogische Studien. 3. Tagilit.- Berg- und hüttenmännische Zeitung 24, 309-312
A SXRD study of an old sample in the collection of the NHM Vienna has confirmed this (U. Kolitsch).
