As i was playing I wanted to build a IC2 machine that required copper ore.I went on mining and I didn't find any IC2 ore at all , and according to a "Let's Play " series , I think I should have found a lot of them.
First I thought it was an biome problem , so I tried to mine in two biomes , but no succes.(This may sound a little noobish :P)
Please anyone help!
