Reigraxius mine

This ancient lead, silver, and zinc mine was already active in 1852. It cultivated a columnar mineralization of argentiferous galena and calamine, located between limestone and Paleozoic schists.

The toponym Reigraxius could derive from the Latin Radicarium = root or place where vine cuttings were rooted; or from the Sardinian Arreiga = radish, it could mean: place rich in plants with a taproot.

The first mining concession was granted to the Ferro family for an extension of 264 hectares.

In 1867, the mine was taken over by Mr. William Scott, who also owned the Marganai forest and the English company Marganai Forest and Mining Company Limited.
