Margin of Error:~112km
Locality type:Mine


Mineralized masses are localized into the ophiolitic masses. Usually the minerals are concentrated into lentiform masses or stockwerks of quartz veins with sulphides or also as "disseminated copper ores".
Probably the first exploration for copper minerals in this area started around 1450.
An intensive mining of the area started in 1857-1859 and saw its end in 1909.
During the fascist era, when there was a shortage of basic materials, most of the mines were re-opened and also these mineralized areas were worked again. From 1939 to 1943 were extracted around 374866 tons of copper ores. With the war, the mines were abandoned.
