Zombie-Infested Iron Mine

Zombie-Infested Iron Mine is a Vampire Counts resource building in Total War: Warhammer. Since before the building of Nagashizzar, Necromancers have used Zombies to burrow and mine mountains for their minerals.

Background
When a Vampire or Necromancer discovers a seam of black iron or something more valuable such as warpstone, then they will send in Zombies to rend the ore from the mountains. Zombies have many advantages over the living in this regard, as they don't require pay, or rest, or indeed any kind of safety considerations!
