Geology

The gold is found in quartz veins mixed with sulphides, hosted by gneiss and metamorphic calcschists. This is a typical orogenic gold deposit with low salinity. The total production of the mine was 4 tons of gold. The mine is very rich in minerals and was quite popular with mineral collectors while it was abandoned.

There are two veins which run inclined by about 45° through the mountain, named Fenillaz and Speranza. The mine accessed this two veins with two tunnels on each level.


Description

The Miniera d'Oro di Brusson (gold mine of Brusson) is located on top of a cliff face above the town Brusson in the Aosta valley. The mine has various names, all derived from the geographic features in the surroundings: Brusson is a town to the west, Fenilliaz is a hamlet to the east, and Monte di Chamousira (1756m asl) is the hill above the mine. The mine has seven levels, between 1532m asl and 1,717m asl, the show mine is in level 7, the lowest level at 1,550m als. There is also a small museum named Museo della Miniera di Chamousira (Chamousira Mine Museum) on the site where once the cableway for the transport of the ore was located. Some historic photographs and maps of the mine can be seen in the Centro di documentazione Joseph Herbet (Joseph Herbet Documentation Center) in Brusson, near the lake.

The Chamousira Mining Park recovery project which reopened the mine for the public was financed by the EU. The first results were the documentation center at Brusson in 2015 and the museum and ticket office which were completed in 2018. The mines seems to be open since 2017 but their homepage is still under construction in 2020. It is obviously possible to wlak the trail and see the mine openings and there are explanatory platzes. But for a tour into the mining tunnels and a visit to the museum you should first check the open hours by telephone or at the documentation center. They are not published so far.
