Hi Carles, there's something wrong with that locality information: The famous locality of St. Andreasberg is not located in Erzgebirge, it is in the Harz Mountains (Erzgebirge is in Saxony, nearly 300 km south of it).
And the land where St. Andreasberg lies is not Sachsen-Anhalt but Lower Saxony.

Cheers!
Tobi

Thanks for your note, Tobi, I'll correct the locality.
