There may be two reasons: - you need 3 people to dig in the mines. If you don't have enough people, then the mine will be empty - for advanced mining (where you can choose what kind of mineral to dig), you need advanced tools (metal tools). If you don't have enough of metal tools (3 for one mine, obviously), the mine stays empty as well.
