Gem Mine (Dwarfs)

Gem Mine is a Dwarfs resource building in Total War: Warhammer. Gem mines are valuable resources, especially if they have a high yield.

Background
Once a shaft is proven to contain a high yield, then more are sunk and a full-sized mine complex is constructed. Naturally, such a valuable resource needs protecting, for Orcs and other creatures like shiny stuff as much as Dwarfs and men, and will try to take it from the Dwarfen miners should they discover its location.
