Pb-Zn-Cu mineralization in baryte-fluorite veins in Permian granophyre, SW of Brusimpiano. A lead mine has been intermittently operating from 1859 to 1865.

A short prospecting adit and some trenches were excavated ("Roncate" prospecting permit) in the period 1953-1954 on the right side of Rio Trallo, at an elevation of 325 m a.s.l. Some samples, consisting of arsenopyrite-löllingite nodules with alteration minerals, were collected at the beginning of the nineties from a fault near the top of the prospect workings. These workings are no longer accessible due to a landslide; a retaining wall with a rock protection net is nowadays the only identificative element of this site.
