Name(s) in local language(s):
Mine de l'Eperon, Carrière de Beauvoir, Échassières, Ébreuil, Allier, Auvergne, France
Quartz vein worked for wolfram by the Montmins Mine company.
The vein is located in the western part of the Beauvoir quarry, where an extension seems to be planned.
Completely forgotten, it has been re-discovered in spring 2017, while looking at a running test boring process. A large dump is present upside a newly traced track.
