Thank you very much for you help everyone

Hi i really like the game and the wiki was very helpful so far but right now I´m a little bit stuck and don't know what to do next. I found my first copper on the surface and digged down beneath it to get more. This way I was able to get my first copper tools (anvil, pickaxe, shear, saw, prospecting pick, hammer). But now I don't know how to get more copper or the next material. As far as I understand it's wasteful to stripmine like in minecraft and I should dig down on a good spot instead, which I have to search with the prospecting pic. But am I at this stage already? I really don't wan't to waste the little copper I have. Thank you for your help! Akreter
