The Iron Ore Mine is the source of Iron Ore 
, it is used only by the Foundry where it is combined with Coal 
in order to create Iron 
. Iron Ore Mine is an Era II building, therefore when transitioning from the Early Steam Era to the Steam Era several Iron Ore Mines will appear in random locations across the map.
Processes
The base version of the Iron Ore Mine generates 1 Iron Ore per Game tick. The mine can be extended with 4 extensions that can be placed on tiles adjacent to the mine. Three of the extensions provide an increase to the Iron Ore output of the Mine, of these extensions the Second Headframe extension provides the largest increase to production output of the Iron Ore Mine. The Timber Tunnel Supports extension adds a new process that consumes Timber 
while providing a large increase to Iron Ore production. When all four upgrades are built onto the Iron Ore Mine, it consumes 0.4 Timber and produces 4 Iron Ore per tick.
There is a secret puzzle in Iron Ore Mine building: Try to build the extensions in a way that the small tracks for mining cars match. It will not add another bonus to the production, but it will become visually much more appealing.
The base building can be connected to the electrical network 
from Era 5 onward, which will increase its production. The amount of electrification production bonus is shown in the brackets.
The base process of the Iron Ore Mine is:
