" Le gisement d'etain de Montebras clejd exploit^ par les anciens gaulois, fournit 

 surtout maintenant de 1'amblygonite (phosphate d'alumine et fluorure double de 

 soude et de lithine) qui est utilisee pour la preparation des sels de lithine. Cette

Tin ores were discovered at Vaulry (Creuse) in 1812 and exploited by the 

 government but given up in the *6C's. Veins carried much columbite wolframite, 

 mispickel, iron-arsenate, native copper, black oxide of copper, molybdenite, uranium- 

 phosphate, fluorite, calcium phosphate, and barite.
