Epithermal vein deposit.
Mined for Ag and other metals from the 14th century until 2006.
The hydrothermal vein system consists of two major veins along fractures that delimitate an andesitic block and a subvolcanic intrusion:
- the Principal Vein
The Principal Vein represents one of the longest hydrothermal veins in Europe, with a length of more than 5 km, a thickness between 0.5 and 22 m and a vertical extension of more than 800 m.
Apparently, six shafts (mines) were operative.
