Name(s) in local language(s):
Miniera di Monte Onixeddu, Gonnesa, Carbonia-Iglesias, Sardegna, Italia
Mine located ESE of Gonnesa.
The mine exploited some lenses and vertical veins of galena and other veins rich in baryte with galena as an accessory.
Some prospects were driven around 1861 by some entrepreneurs (Eyquem, Asproni, Christian, and Rossi). The mine was officially discovered in 1867 and definitively ceased operations in 1983.
To the south-east, in an area adjacent to the mine, i.e. at Monte Sa Bagattu, a prospect permit for baryte was granted to the company SocietΓ Italiana del Litopone in 1938. Here, some works were also performed in 1981 by the company Baroid International.
Baryte (in particular the dark green, large tabular crystals perched on dolomite in association with grey calcite), pseudomorphs of quartz after baryte, calcite, and phosgenite are the most interesting minerals for the collectors.
