Old iron mine at an elevation of about 2350 m in the upper part of Lusignetto valley, at the foot of Monte Rosso d’Ala, above Alpe Radis. Mining operations were performed from 1823 to 1869; the iron ore was transported by sled to Ala di Stura and processed in a foundry, known as “La Fabbrica” or “Le Vote”. Although various prospecting permits had been recorded during the XX century, mining operations restarted no more.
The iron mineralisation is included in a serpentinised tectonic peridotite at the contact between ultrabasites and metagabbros. It appears to derive from the transformation of stratiform chromitite bodies (Rossetti, 2000) and is made up of a banded sequence: the main magnetite body in gangue of chlorite ± diopside; a partly serpentinised peridotite rich in forsterite; a magnetite layer in chlorite gangue passing to garnet-, perovskite-, magnetite-bearing chlorite schist. Cr-free neoblastic magnetite, which surrounds microscopic relics of chromite, and abundant uvarovite, as chromite replacement product, among the magnetite layers are the distinctive features of this mineralisation.
