The documentary film by director Stefania Porcheddu, "Argento vivo", is titled "Living Silver" and tells the story of the mining village of Argentiera. The work will be screened on Monday at 10 am in the Aula Magna A of the Department of History, Human Sciences and Education at the University of Sassari. The initiative is by the "Fiorenzo Serra" Visual Anthropology Laboratory of the Società Umanitaria.

The deposits, rich in silver lead, were already known in Roman times and were exploited in the Middle Ages. The mine experienced a new epic starting from the second half of the nineteenth century, with the resumption of mining activity and the progressive development of a village, which became the main inhabited center of Nurra.

The mine was managed until 1924 by Correboi, a company with Ligurian capital; then it was taken over by the multinational Pertusola, which decided to close it in 1963. Since then, Argentiera has undergone an inexorable depopulation; it currently has about 60 residents and has been waiting for a long time for a real tourist development of the area.

Stefania Porcheddu's documentary reconnects the threads of the mining epic, with the direct testimonies of those who worked and toiled in the mine, an emotional story and anecdotes proudly told by Giovanni Matteo Ortu and Giovanni Deroma. A community and human story that emerges from the lives of the workers, children and heirs of that mining reality, which has left an indestructible monument of industrial archaeology.

The speakers include director Stefania Porcheddu, historian Sandro Ruju who wrote a valuable volume on Argentiera, art historian Alessandro Ponzeletti at the Academy of Fine Arts in Sassari, DISSUF geographer Prof. Valeria Panizza, and the director of the Margherita High School in Castelvì Prof. Gianfranco Strinna.
