6840-m-long pressure tunnel between the Valle di Lei reservoir and the underground Ferrera hydropower plant. A carbonate-hosted U-Pb-Zn-Cu-Mo mineralisation has been evidenced between metres 529 and 534 of the gallery.
The mineralisation consists of dolomite-calcite-quartz-baryte veinlets with pyrite, uraninite, Se-rich galena, tetrahedrite, sphalerite, chalcopyrite, bornite, covellite, and molybdenite in the dolomitic marbles of the Suretta nappe.
