So i have two questions regarding mining. I really coundn't find this information anywhere.
1) Is it still possible to find ores other than Chalcopyrite on level 1? I have literally found 16 individual nodes of Chalcopyrite and nothing else so far. Was it changed and not mentioned anywhere or am i extremely unlucky?
2) How do quality nodes propagate between mine levels? For example if I find a node of Q40 Chalcopyrite on level 1, is chalcopyrite on level 2 directly below going to be higher Q as well, or are every levels' nodes completely independent?
