Pneumatolytic-hydrothermal quartz-cassiterite-beryl-arsenopyrite-molybdenite veins.
Probably worked in the Roman era.
About 10 pits have been dug in the past from 1853 onwards, 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.
The remaining buildings have been restored and turned 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 is now private property and collecting is prohibited.
