Manganese deposit, situated at an altitude of 560-570 m at the head of the little valley of Vajo (Vaio) Siresol, near the contact between tuffs and brecciola (a limestone breccia that is deposited by turbid water and is intraformational in character) at the base and yellowish Eocene limestones at the top. In this deposit, exploited at the beginning of the 20th century by the company Società Minerali Manganesiferi Veronesi, three galleries were excavated. Only two of them are now accessible, while the third one is completely collapsed. The main adit, driven at an elevation of 560 m, consist of about 150 m of underground workings, while the second gallery, situated 370 m south of the main workings at an elevation of 570 m, is only partly accessible (20 m).
Pyrolusite, the most abundant manganese mineral at the mine, is black, powdery massive or forms dull arborescent or radiating aggregates with metallic lustre on the fresh fracture; ramsdellite appears as bright black crystals attaining some millimetres in length; ranciéite, associated with minor cryptomelane and todorokite, forms typical silvery bronze lamellar aggregates and incrustations; quartz appears as hyalin or milky prisms attaining some millimetres in length and calcite as small colourless to white rhombohedral or scalenohedral crystals.
