Resources

[Guid]

If I find a resource on a map such as Iron, how do I get use out of this. Can I just build a road to the resource, or do I have to build a mine on the resource?

A road connected to your road network will do. Resources also give bonuses to cities able to work that tile.

Two things:

1) it has to be connected to your trade network by road/rail

2) it has to be within your cultural borders. Otherwise, you can use a worker to build a colony on top of it. Colonies can be outside of your borders but can be culturally absorbed by other Civs.

You don't have to mine the resources
