You can build Mines on the Kingdom Map to get more resources and then send troops to gather the resources. You can build Mines to collect Iron, Stone, Lumber, Silver, Food, and Gold. Unlike other Mines, Gold Mines can be built on any map tile. You cannot build Mines on the territory of a Clan of which you are not a member.
The level of your Mines depends on your City's Capitol level. You can view more details by selecting "Stats" in your Capitol's interface.You need the required number of Great Architect's Blueprints in order to build a mine. The number of Blueprints required increases with the mine's level.
Please note that you can only have a maximum of two Mines built on the Kingdom Map at any one time.As well as building your own Mines, you can also capture Mines that are generated by the game. Game-generated Mines contain less resources and have a significantly shorter duration on the map. As well as the types of Mines that are available to be built, the game also generates other unique Mines, such as Dragon Mounds, Mountains of Gold, and Wellspring Ruins. The first two of these allow you to gather Gold, while the latter allows you to gather Tar. Mountains of Gold are only available in the Kingdom that won the Clash of Kingdoms tournament.
The base harvesting speed in Mines varies depending on the resource being gathered — the more precious the resource, the slower the gathering process. The total amount of resources gathered depends on the total carrying capacity of the troops sent to the Mine.
