Most mining developments are built in isolated locations, but this mine 400km north of the Arctic Circle takes inhospitable to a whole new level.
Operated by Sydvaranger Gruve, this iron ore project in Norway has plenty of history behind it.
The tunnels pictured below were built into a solid rock mountain and were used as a bomb shelter during World War 2.
The conveyor network exceeds several kilometres, and was large enough to protect the local town's entire population during bombing raids.
Another fun fact: the water on the ground is coming straight up from the water table.
