There is clear evidence that mining began here in the 12th or 13th century and ended around the year 1770.

The pit developed two quartz veins, of up to 1.5 metres thickness.

The veins contain galena and fahlerz, as well as iron-manganese and copper-oxide.

[1] In 1978, under the direction of the local history society, work on the Erzknappenstollen adit began.

Between 1984 and 2005, further excavation projects made other parts of the mine accessible, so that both the Upper and Lower Adits (Obere and Untere Stollen) could be visited.
