"Mining facility. Automatically extracts raw minerals from passing asteroids."
The Mine is a 2x2 room that lets you farm Mineral without having to battle. This isn't nearly as useful as the Gas Collector as Gas has alot more uses than Minerals in the game. Often times, you can complete all Mineral upgrades and still only be halfway done on Gas upgrades. However, if you struggle with getting Minerals, this is a great tool.
