Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction.
Obtaining[]
Resource acquisition[]
Limestone can be harvested by hand (default E) in trace amounts from resource deposits scattered across the world, or from inexhaustible resource nodes on which Miners can be constructed to extract automatically. Additionally, Lizard Doggos will occasionally bring it when tamed.

Mk.3 mining rate at 250 % |
|---|---|---|---|
| Impure | 12 | 1,440 | 3,600 |
| Normal | 47 | 11,280 | 28,200 |
| Pure | 27 | 12,960 | 21,060* / 32,400 |
| Total | 86 | 25,680 | 52,860* / 64,200 |
*Note: The extraction rate of a Miner Mk.3 at 250 % is 1,200/min, but a Mk.5 Conveyor can only carry 780/min, therefore the maximum mined amount cannot be transported.
Extraction energy[]
It takes about 10.7 MJ to extract 1 Limestone. Further reading: Extraction energy
