Miniera San Benedetto, Iglesias, Carbonia-Iglesias, Sardegna, Italia


This mine is interesting for the occurrence of gaspéite. The San Benedetto Mine ore bodies are massive and not concordant with embedding rocks.

The minerals are mainly Zn carbonates and Fe hydroxides. The main ores are found from around 50 m depth from this alteration area but are still present at 200 m of depth. Between the sphalerite and galena, there are considerable masses of oxides, in which cavities gaspéite has been found as well.

The mine was part of the Belgian Vieille-Montagne group from 1872 to 1941.



In 1869 the mine was discovered by Ing. Leone Gouin who started the exploitation of this silver-containing galena and calamine deposit. He built a mechanical preparation workshop, a railway line, and 5 calcination furnaces. In 1872 the concession was taken over by the Belgian group Vieille Montagne. A village was built for the workers, as well as a production shaft and a drainage corridor. Vieille Montagne sold everything in 1941.

In 1941 the mine of San Benedetto and Coremò was taken over by the Società Anonima Nichelio and Metalli Nobili, belonging to the AMMI group.
After the Second World War, the concession passed to the SAPEZ, which invested in the modernization of the accommodations. The Zimmermann shaft was also modernized and deepened, the ore was sent to the washing plants of the Barraxiutta mine for flotation processing.

In 1990 followed the closure of the installations, although they still produced 200 tons of raw ore every day (with a high content of zinc).
