The mine provides Iron for the town to be used in :
You can have as many mines as you need/want, only limited by resource area available space. The maximum number of mines you can build in your village therefore is 22. Upgrading the mine is necessary to upgrade the forge, it is therefore the only resource building necessary to upgrade if you want to upgrade the Palace to the next level as fast as possible.
The mine is the least productive resource building (besides iron) and also the longest to upgrade.
For a complete tutorial on hyper farming (required after you get to lv 21-22) you can visit the Hyper-Farming page
Requirements : You need a palace of the same level to upgrade a mine to the next level.
