A mining area that is recorded from the 15th century is located to the east of Pöhlberg. The extensive mining of silver-bearing copper ore is mainly documented by the heaps and the preserved underground mine workings that are unique in Erzgebirge mining. After the introduction of the liquation process, silver was extracted in the Grünthal Liquation Hut Complex from the copper ore mined here. As a result, mines such as Heilige Dreifaltigkeit and St. Briccius regained importance.
