Miniera Torgola is a vast, abandoned fluorite mine hidden within the steep slopes of Val Trompia, a region once known for its prolific iron trade. The site bears the marks of centuries of extraction, with its roots going back to early silver mining efforts.

By the early 1900s, the Martelli company had transformed the site into a hub for fluorite extraction. During the 1950s, the mine expanded rapidly to meet rising industrial demand. Production reached its peak in the 1960s before entering a gradual decline, ultimately ceasing operations in 1999.

Today, the structures remain, though weathered and dangerous. Inside, corroded metal walkways and collapsing floors make exploration risky. Conveyor belts still stretch between decaying buildings, and carriage tunnels near the Mella River are locked behind rusting gates. A ruined sorting and crushing plant lies near the main shaft, silent testimony to the scale of former operations. No safety measures exist, and no restoration efforts have been made.

In the debris, remnants of fluorite can still be found, a small hint of the mine’s former purpose. A particularly notable discovery was a small white sample bag, dated 13.4.88, labeled with the chemical composition of its contents: primarily CaF₂ (86.22%), with smaller amounts of PbO₂, SiO₂, and sulfur. This suggests active mineral analysis and documentation continued into the late 1980s.

Though reachable via the main road through Collio, this place is not for the careless—it is raw, powerful, and fading fast.
