Concessione mineraria Tre Monti, Liguria, Italia
The old Tre Monti mining concession for manganese ore extraction embraced three mountains, which form the boundary between the provinces of Genova and La Spezia: Monte Alpe, Monte Zenone, and Monte Porcile.
Monte Alpe mine was operated on the western and eastern slopes of Monte Alpe (also known as Monte Alpe di Maissana), in the municipal territories of Castiglione Chiavarese (Genova) and Maissana (La Spezia); Monte Zenone mine was operated on the western and eastern slopes of Monte Zenone, in the municipal territories of Bargone (Genova) and Maissana (La Spezia); Monte Porcile mine mine was operated on the southern slope of Monte Porcile, in the municiapl territories of Maissana (La Spezia).
The name "Tre Monti" appeared for the first time in 1889, when a prospecting concession was granted to Augusto Parma and Stefano Sturla. Due to difficult logistics, mining was interrupted and restarted many times during the 19th and 20th centuries; it definitively ceased in the 1970s.
