I've just recently started up mining on my lvl 40 Paladin. The first 80 levels were easy as copper veins are spread throughout the lowbie areas. Tin is a bit harder because there isn't much of it, but when smelting bronze turned gray at level 100 and mining tin/silver is my only option (as iron mining won't be an option until level 125) I'm stuck!
I've seen a silver vein two times today, one time where it was hidden inside a rock (!). I can only gain levels from smelting silver or mining tin/silver, though I don't know for how long tin will give me levels.
Any advice on how to break 125 so I can start mining all the delicious iron in Arathi?
I've been grinding a bit on incendicite and bloodstone in Wetlands and Arathi Highlands, but I'm not sure for how long they'll stay yellow/green.
