Building Overview: Iron Mine

In Kingdom Strike, Iron Mines are where you extract and store iron. Upgrading an Iron Mine will give it a larger capacity and increase its iron productivity. At the late stages of the game, iron tends to run out fast. [How to Build an Iron Mine]

Building an Iron Mine requires: Lv. 10 Palace, Wood x200, and an empty plot.

Tap on an empty plot and the Construction interface will appear. Then, tap Iron Mine to start construction.

The number of Iron Mines a ruler can build is decided by their Palace level. At Palace Lv. 10, they can build up to four Iron Mines. [How to Upgrade an Iron Mine]

A ruler's Palace level decides their Iron Mine's maximum level. It costs wood to upgrade Iron Mines.

Benefits of upgrading an Iron Mine: increased iron productivity and storage capacity.

Tap the Iron Mine you want to upgrade to bring up three options: Details, Upgrade, and Buff (Coins). Tap "Upgrade", and the "Upgrade Building" interface will appear. Here, you can see the Palace level requirement and wood cost for the upgrade, as well as your current wood. If your Palace level and current wood both meet the requirements, you can tap the final "Upgrade" button. [Iron Mine Stats] Tip: While an Iron Mine's iron productivity and storage capacity are greatly influenced by its level, you should also keep in mind your technologies, buff (items) and ruler skills, as they can affect these stats, as well. [How to Remove an Iron Mine]

Don't remove your Iron Mine unless you absolutely have to. Removing your Iron Mine will lower your Power.

If you have no choice but to remove an Iron Mine, you can do so as follows:

Tap the Iron Mine you want to Remove, then tap the "Details" button to bring up two options: Remove and Relocate.

Remove: The selected Iron Mine will disappear and become an empty plot. You can construct another building on this empty space later. Removing an Iron Mine consumes no resources.

Relocate: This option moves the selected Iron Mine to a new location (the current location will become an empty plot) or swaps the Iron Mine with another building.

Summary: As shown in the table above, Iron Mines of different levels provide different amounts of iron. The higher an Iron Mine's level, the more iron and Power it will net, making Iron Mine construction and upgrading a crucial aspect in this game.
