Mining operations date back to the last decades of the 1800s, when interest was directed mainly at the extraction of pyrite, as evidenced by a series of prospecting and mining permits. Starting from the early 1900s the interest shifted towards talc, mined in considerable quantity, and asbestos, mined as an accessory.
The mining history of this area is complicated, and the names of some prospecting and mining permits are not univocally interpretable. In recent times a mining license for talc and asbestos, named "Bracchiello", was granted to the company "Talco Piton" for the period 1981-1984, but it never became effective because the company ceased its activity in 1982. In 1985 the company Edilcave applied for a mining license with identical name for talc and associated minerals, but the works never started due to the asbestos hazard.
From a mineralogical point of view, parallel intergrowths of fibrous tremolite and antigorite have been described here in recent times (Belluso et al., 1995).
This locality is located in the Ala Valley, but included in the municipality of Ceres.
