Talk:Adv. Iron Mine/@comment-6411177-20130218162645

I am almost always in need of more iron. I built one and put an iron smelter next to it. After upgrading to level 6 I get 144 Iron per hour just from one Adv. iron mine. The Adv. Iron Mine is one of my best purchases in this game. It gets me almost as much iron as my 3 regular iron mines (also at level 5 or 6) combined.
