Former iron mine on a strip of serpentinite in morphological relief between the Grondona torrent and the Canale delle Miniere; in the immediate vicinity, in a strip of serpentinite that emerges between landslide deposits, there was instead a former copper mine. These locations are reported with precision in the pre-unitary Austrian cartography, where they are indicated with the names of "Min. di Ferro" and "Miniera di Rame". These are places that exemplify the different areas that formed the metal-bearing basin of the upper Nure Valley, linked to the history of the Ferriere factories.
