Iron Mine

Overview
An Iron Mine allows players to harvest  Iron per hour and more with upgrades. As a lot of units and buildings require Iron, this is a very important building to make. There are seven Iron Deposits on the map.

An Adv. Iron Mine allows players to harvest Iron at twice the rate of a normal Iron Mine.

Since the 1.1 Patch, players can build Iron Smelters to give a bonus to production on Iron Mines.
