Vieille Montagne
The Société des mines et fonderies de zinc de la Vieille-Montagne (French; lit. 'Company for Mines and Foundries of Zinc at Vieille-Montagne') was a Belgian mining company which produced zinc. The company took its name from an important zinc mine known as "old mountain" or "old mine" (Altenberg) located near Kelmis. The mine was once a bone of contention between Prussia on the one side and the United Kingdom of the Netherlands (later Belgium) on the other, that resulted in a piece of land that became the territory of Neutral Moresnet.
