Name(s) in local language(s): "la mine" "mine de la Villeder" (ou Ville Der)
Pneumatolytic-hydrothermal quartz-cassiterite-beryl-arsenopyrite-molybdenite veins.
About 10 pits have been digged in the past from 1853 on, among them the "puit Saint Michel" 256m deep, with numerous galleries. All the pits are now flooded and secured. The works lasted from ~1856 to 1916, with only minor ore production. Probably worked in the Roman era.
The remaining buildings have been restored and turned in the recent years into a museum and a brewery.
An open cut ("la grande tranchée" ou "la grande carrière": "the great open cut " or "the great quarry")has been worked too: it still exists, but nowadays in a private property and collecting is prohibited.
