Old Hg mine, in which cinnabar occurs in Pliocene sands, operated in the period 1898-1971.

Ownership of the mine has changed through the years:
1898-1917: Engineer Enrico Jasinki, followed by his heirs.
1917-1921: Banca Italiana di Sconto. With the failure of the bank, the mine is abandoned.
1927-1939: Società Italiana Anonima Mercurio, owned by G. Ricciarelli of Castell'Azzara.
1939-1971: The group Auletta Armenise acquires the Società.
In 1971, after the renunciation of the concession, the mine is finally abandoned.

Current status: the buildings housing the furnaces, some small extraction facilities, and a few buildings are all in poor condition.

Cinnabar appears as tiny detrital individuals admixed with grains of lithoid minerals (quartz, feldspar, and minor mica) in the form of lenticular masses, thin discontinuous layers, and highly coherent reniform, nodular, or bizarre concretions (locally known as "tozzi"). Cinnabar is sometimes associated with minor pyrite or marcasite.

Exact locality coordinates are N 42.621581° E 11.362588° (decimal degrees WGS 84, from direct knowledge of the site tied to satellite images).
