After finally whipping up a batch of thorium I was excited to go to the AH, thinking I'd get a nice bounty for all my hard effort as the nodes sometimes gave me only 1 ore. When I finally got there I saw that thorium goes for in the 4g area, the same amount a stack of mithril is. I was forced to sell it for 3g 99s to make sure mine sells where as I usually sell mithril for 4g with no trouble. So, apparently on my server mithril is the far better choice, being more abundant and selling as well as thorium.
Would anyone be willing to share any good spots to farm some mithril?
