Name(s) in local language(s):
Miniera di Cuzzago (Miniera della Freva; Miniera del Buèr; Miniera di Cuzzago & Nibbio), Premosello Chiovenda, Val d'Ossola, Provincia del Verbano-Cusio-Ossola, Piemonte, Italia


Old Fe-Cu mine (with very minor Ni). It consists of several adits scattered in the rock wall. The main ore mineral is pyrrhotite. The ore is hosted in "volcano-sedimentary" mineralizations later re-arranged under regional metamorphism (close to the transition from amphibolite to granulite facies). The host rocks belongs to the kinzingite series of the "Ivrea-Verbano Complex".

Note: for this old mining area, located between the villages of Nibbio (Mergozzo municipality) and Cuzzago (a former separated municipality, from 1928 annexed to the one of Premosello Chiovenda), various names have been used by different authors (Cuzzago mine, Freva mine, Buèr mine, Cuzzago and Nibbio mine). Scaini (1971) used for this locality the misleading name Nibbio mine, which better identified the mine (short adit) located at Turrio (Motto del Turrio), between the villages of Nibbio and Bettola [see: http://www.mindat.org/loc-187814.html].
