Mining
Each 
Faction has its own mining 
Building that do the same thing. The 
Iron Teeth just do it more efficiently. These buildings are the 
Mine 
and the Efficient Mine 
. Mining can only be built on 
Underground Ruins. They do not harvest from 
Ruins, that is the job of 
Scavenger Flags.
Usage
Mining consumes various materials to produce 
Scrap Metal. This is the only way to get infinite amounts of Scrap. Scrap is 
smelted into 
Metal Blocks for use in constructing advanced, end-game structures.
Mining employs up to 10 
Workers who run a high risk of 
Injury.
Strategies
Due to injury rates and consumption requirements of mining, it is preferable to scavenge scrap from 
Maps until little remains. Additionally, mining requires a lot of 
Science research to unlock.
Once mining commences, it is usually unnecessary to have them fully staffed. There are times of great metal consumption when you increase the number of workers, but this is usually not straight away. Regardless of staffing levels, prepare for the incoming injuries by increasing the number of 
Medical Beds. When you have sufficient 
Bots, you should prioritize replacing mining workers with them. Until this happens, minimize your staffing of your mining operations to keep injury rates manageable.
Given the quantity of consumables used in mining, mining buildings especially benefit from having adjacent 
Storage of these consumables and ample storage for the Scrap they produce.
