In Tropico 4, when I select to construct a mine I get an overlay showing the location and density of ressources.
Do I build the mine right on top of that or rather beneath the ressource field?
I am pretty sure I once built a gold mine directly on top of the ressources and it was unable to mine anything.
Same with farms: When I want to build a farm, I see which area is best for growth. Do I build the farm into this area, or right beneath it so the field will be there?
