Iron, ore and mines
Iron in Build and Conquer: the raised 12-mine limit, how ore becomes the steel that missiles are built from, and how to keep the truck chain that moves it.
Iron comes out of mines — the limit was raised from 10 to 12, so run all of them. It feeds refineries and the steel works, and steel is the input that limits how many missiles you can build.
Iron is the start of the chain that ends in missiles in Build and Conquer. It is also the chain with the most places to break: mines produce ore, refineries process it, steel works turn it into steel, and trucks move it between all of them.

Key facts
| Item | Detail |
|---|---|
| Mine limit | Raised from 10 to 12 — deploy all of them |
| Output | Raw ore and materials for refining |
| Next step | Refineries, then the steel works |
| Delivery | Trucks; the truck chain was visibly broken for a day and patched |
Why steel is the real bottleneck
Every missile and interceptor in the game costs steel, fuel and money. Money you can always make; fuel you can refine; but if the steel works is idle or the trucks are stuck, your entire war capacity is zero — and the game does not send you a warning.
So the routine that matters: check the trucks first. When military production stalls, that is almost always where it stopped.
Getting more out of the ore
- Run all 12 mines. There is no downside except power draw.
- Locate the steel works between the mines and the factories so deliveries are short.
- Upgrade before expanding. A bigger refinery processes more per plot than a second small one.
- Keep the district powered — an unpowered refinery produces nothing while still costing upkeep.
The rest of the chain: fuel and refineries, factories, and the resources guide that ties them together.
