Carbite

Carbite is (Kinda rare) You can find it in the Salt flats and Deserts more common in Salt flats. If you destroyed the rock you will get a few carbite Ore chunks, but If you put a Auto miner on top it would take more carbite from the rock. If you Refine the carbite ore with the Refinery You will get Carbius brick which can be made into alot of things.
