Iron Industry
A single-level building: there is nothing to upgrade it into.
Iron Exports (Special exports)

Here, metal can be poured, moulded and shaped into strength, wealth, and occasional cooking implements.
At the foundry, molten iron flows like fine wine at a victory feast, only it's less drinkable and more deadly.
Here, everything gets the iron treatment: from weapons that will cleave through shields to plows that will turn your fields into lunch.
This place is where iron gets beaten into submission, shaped into anything from armor to the occasional badly made frying pan. If it’s made of iron, it came from here.

What it does
"True income is below | IGNORE:" on the building card. The number the game prints after that label is this level's mining value (listed below as *mining income*, or as a *mine resource* bonus added to the mine's), and it is a multiplier, not money. Each turn the settlement earns 5 × that value × the worth of the region's minerals (each mineral's trade value times how much of it the region holds). The card labels the raw number IGNORE because the money you actually get is written out on the card lines underneath it: *Mining income from …: +N per turn*.
