Miniera di Montaldo (Miniera di Montaldo di Mondovì, "Ponte dei Gorrazzi"), Borgata Oberti, Montaldo di Mondovì, Val Corsaglia, Provincia di Cuneo, Piemonte, Italia
A Fe-Mn deposit in Ligurian Briançonnais Domain in the localities Frazze and Rocconi, near Borgata Oberti.
It was mined for iron on a small scale in the mid-19th century, but industrial exploitation dates from 1872. Various galleries were opened on both sides of the Corsaglia stream and a shaft was excavated on the right side. Operations definitely ceased by the mid 1950s.
Fe-Mn ore occurs in quartz arenites and adjoining marbles in layers, boudins and, subordinately, in mineralised veins. Secondary hematite-bearing veinlets crosscut both quartz arenites and marbles.
The mineralisation mainly consists of cryptomelane-group minerals +/- hematite +/- braunite, with variable amounts of quartz, calcite, Fe-Mn-rich phengite and aegirine. A distinguishing characteristic of this mineralisation is the presence of numerous arsenates (berzeliite, chernovite-(Y), manganberzeliite, piccoliite, svabite, talmessite, tilasite, and three unnamed phases containing respectively Ca-Ce, La, and Nd: now armellinoite-(Ce), gasparite-(La) and the Nd unnamed monazite group mineral).
Montaldo mine is one of the two type localities for piccoliite (IMA No. 2017-016), a Na-Ca-Mn3+ arsenate, topologically equivalent to pilawite-(Y). Piccoliite occurs in quartz-calcite veins in association with calcite, berzeliite/manganberzeliite and, very rarely, with unnamed REE analogues of chernovite-(Y). Piccoliite forms aggregates of black anhedral crystals, embedded in the quartz matrix, and rarely black well-developed prisms. It is brittle with irregular fracture and has brown streak and resinous lustre (Cámara et al., 2017b).
Note: The locality name "Ponte dei Gorrazzi Fe-Mn deposit" used in some bibliographic references is not correct.
