Question about plots working

[err76]

Sorry if this is covered somewhere else

Last night against the computer I was upgrading to Frigates and ran out of iron. Thinking I had no iron mines I started looking around i did have 2 iron mine plots that were developed into mines but I do not think they were producing. Do I need to have workers there actively working it?

Thanks for the help.

Each mine will only give you enough iron for so many units. The same is true, for example, of horse pastures when building horsemen. There's usually a resource counter at the top of your screen that tells you how much of that resource you have left that's available for building what you want. You don't need to leave a worker there. Perhaps you used what was there and you ran out?
