Stone, iron and coal | Production and processing of resources Banished Guide
Last update: 11 May 2016
In case of stone and iron the initial plan of mining is simple - try to exploit most of natural resources by workers. They will give you enough supplies for at least a few years. Remember that they're not renewable, so you should save some mining spots of both resources for an emergency.
You can build a quarry in any place, regardless of the availability of resources. Stone can be mined by up to a few dozen workers - remember that the amount of it is not infinite and you can't build anything in a place where a quarry was. Try to place them away from the town.
Mine is used for collecting iron and coal, but you can build it only in the mountains. You can't mine two resources at once, you need to choose only one or keep changing between them. Iron is definitely more versatile, it's used for construction of buildings and making tools. Coal is a more effective source of heat, but it's not much better than firewood. You can also use it to create steel tools, so coal is definitely less versatile.
