San Leone Mine, Assemini, Cagliari Province, Sardinia, Italy

Miniera di San Leone, Assemini, Cagliari, Sardegna, Italia

This iron mine is located in Sulcis area, and it can be visited only with owner's permission.
The mine is almost "recent" - the occurrence was discovered in 1860 during the development of industrial age which needed always more and more prime matters and increasing quantities of minerals. In 1892 the mine started its activity, which ended in 1963.

The mineralisation is mainly represented by magnetite ore bodies within skarn generated by the thermometamorphism of previous paleozoic limestones at contact with granitic intrusions.

Near this mine, there are some radiometric anomalies due to some uranium minerals (see other locality area named San Leone area, Assemini, Cagliari Province, Sardinia, Italy)
