Miniera di Zorzone (Miniera di Gorno), Val Vedra, Oltre il Colle, Val Brembana, Bergamo, Lombardia, Italia


Alpine-type Zn-Pb-Ag deposit (similar to Mississippi Valley type deposits), broadly stratabound with some discordant mineralisation composed of breccia bodies and veining. The deposit has a generally simple mineralogy with low-iron sphalerite, galena, and pyrite.

Mineralisation is similar to that of the Paglio Pignolino Mine.

The Gorno mine has a long history. If we limit ourselves to modern times, we know that the exploitation of zinc and lead ore began in 1888 with the arrival of the English group Crown Spelter. In 1920 the Belgian Group Vieille Montagne took over the activities. VM made a number of improvements and continued operations until 1940. A disastrous year for VM in which they, in addition to the activities in Bergamo, also had to abandon those in Sardinia. Gorno was taken over by the Italian group AMMI, which continued the activities until 1985. And finally, SAMIM took over the treatment activities until 1985.


Ores of the Gorno mine were taken by teleferica (cable line) to Oltre il Colle and from there to the wash plant in Riso.

During the VM-period, the ores were taken to Viviez, France, also VM.
After the war, thanks to the Marshall Plan, a proper zinc plant was built in Ponte Nossa.

New activities at the Gorno Zorzone zinc mine

In the Quarterly Activities Report for the period ending 30 Sept. 2018, Alta Zinc Ltd. announced the plans for the Gorno Zinc Project. They confirmed the intention to build an underground crushing and ore sorting installation. They also confirm the intention to build a flotation plant, to be constructed on the old Riso site.

The local population is positive about the new mine activities.

Warning: the mine has resumed activity ("Gorno Zinc Project"), work is underway for the safety of the tunnels, access to the area is forbidden!
