Aosta Valley tremolite, Torino

Asbestos was worked in the Aosta Valley of northern Italy, in deposits that Asbestos, the industry's trade journal, said in 1931 had "been under operation here since 1865, located at about 1600 meters (5249 ft.) above the sea level," with the asbestos "carried to the village by sleighs or mules."¹ The same article said that production "is now limited, almost all mines having been inactive since 1905."¹ The U.S. Bureau of Mines' Minerals Yearbook said in 1935 that asbestos "is mined also in the Aosta Valley, northeastern Torino."² In 1938 the trade journal reported that Asbestos Quarries Limited of London "now owns and controls some of these mines in the Aosta Valley."³

The documents report this mine producing asbestos fiber for sale.¹
