The mine was used in ancient times as a silver and lead mine. It was used in modern times as a fluorite mine by the Gewerkschaft Finstergrund. Mining ceased 1972. In 1982 the mine was reopened as a visitors mine. It is just a few hundred meters off the main road from Wieden to Utzenfeld. As of 2016 the mine is open from May to October on Saturdays and Sundays and public holidays. Other times can be inquired at their website (www.finstergrund.de) Currently only the level 5 adit is accessible via an underground electric train. During opening times the forest road is open but the road will be closed in the evenings. Parking is right in front of the mine entrance. There is also a little restaurant at the site.
The visitors mine is run by the mining association “Bergmannsverein Finstergrund Wieden e.V.”

"Fluorite vein mineralization at the Finstergrund deposit evolved over three fluid generations, was derived from gneissic source aquifers and comprises five distinct fluorite REE groups: the first fluid generation is characterized by fluorite precipitation above 200 ∘C (“group III”), below 200 ∘C (“group I”) and after fractional crystallization (“group IV”); the second generation comprises remobilized fluorite (“group II”); and the third generation revealed fluorite precipitation by meteoric water mixing (“group V”)." (Hintzen et al., 2023).
