The Iron Mine produces iron. Iron is a key ingredient in most buildings; required for troop building; and also used in technology research. We recommend upgrading your resource production buildings each time you upgrade your Castle to make sure you have enough resource production to upgrade constantly.
Iron is the most commonly used resource. As you reach higher levels, you will notice your iron depleting faster than all others. For this reason, you should supplement by gathering iron with idle troops.
The table below shows the power level, power level increase, time to build, and a rough estimate of the power points increate per minute to upgrade each level. The power per minute statistic is useful for Clash of Province and Hourly Challenge reward chests.
Note: Build times vary as you increase your technology, alliance technology, and Royal Prestige perks such as the Worker’s Guild. Build Time and Power / Minute calculations may differ as much as 20% from the chart below. These figures were taken from numerous accounts with varying building time reductions. We’re in the process of rebuilding our data to only show times without buffs.
|Level||Power||Increase||Build Time||Power / Minute|
This build time / power chart applies to multiple Rise of Empires buildings. These include Charcoal Factory; Distillery; Iron Mine; Lumber Yard; and Quarry.
