Name(s) in local language(s): Miniera di Cerchiara, Borghetto Vara / Pignone, Val di Vara, La Spezia, Liguria, Italia
 
This area [which is situated on the municipalities of Borghetto Vara and Pignone, near Faggiona (Pignone)] is certainly known since 1600, when hematite, associated to Mn minerals, was mined by locals to extract iron. The deliberate mining of Mn minerals started in 1790 and ended after WW II.

The Mn minerals are bound to jasper formations of Jurassic age.
