Different Resource-types on Calyx
There are four differnet resource-types avaiable on Calxy: Copper, Iron, Limestone and Atlantum.
All resources on Calyx are collectable by hand using the picaxe or throu the usage of one of the avaiable miners.
The resource-veins are finite, so they will be consumed by hand-harvesting or using the miners.
Due to this fact the Groundbreaker has to replace his miners from time to time to ensure the supply of his factory with all the needed resources.
If a vein is exhausted, the Groundbreaker has to develop a new vein of these resources.
