Iron

Iron is the easiest resource to obtain through Resource Discovery items and is the first time most nations will start producing Metal. Iron can be found on all continents. 
The Iron icon is the same as the icon for Mountains and Stonesilver. 
== Obtaining ==
 Iron can be found naturally using a Tier 2 Geologist. Iron has a good (i.e. green) chance of being found on every continent. Iron is the only resource that has a good chance of being found on every continent ( Whales and Silver can be found on every continent but don't have five greens).
Iron can also be obtained through the Ballast card in Overseas Exploration. Exhausting this card gives you 20t iron.
I exhausted the card, but the Iron hasn't turned up.
You will need to use a geologist to find the Iron from the card.
== Research ==
You don't need to do any research to find Iron itself, but if you want to smelt it and turn it into Metal, you will need to research the Basic Smelting technology before you can build Iron Smelters.
== Uses ==
 Iron can only be used to construct the Iron Smelter. This is exactly the same as the Bauxite Mine, so the two can be used interchangeably. While they're not the most efficient factories, they can produce a nice bonus amount of Metal because at early tiers you won't need an awful lot of Metal.
