if you are ally a great place to start is in the fargodeep mine in elwynn
then when you can mine tin go to DM, there will be some silver in there also.
there are LOADS of iron veins in STV.
run around the outskirts of Arathi for a while and you will get a shed load of mithril.
WPL is great for thorium, and so is burning steppes i believe
run around winterspring for a while and you will slowly get upto 300 by mining small/rich thorium.
if you are engineering i suggest you make a mining helm so you can start mining fel iron ASAP.
once you get to 300, the amount of fel iron in HFP is just insane.
hope that helps, if you are horde.....then...i rely dnt know, kinda the same i guess
