So
I started playing again after a long break, and i am just learning my way around the new mining system.
However, when i decided to start my copper production - much to my surprise, even though the mine was built on a copper node, the first thing seam i hit is iron??
So my question is this: Is it possible to find all types of ore in all mines? And, when the game shows it as a copper node - does that only mean that there is more copper than iron?
