Been mining here ever since I started leveling in The Storm Peaks as well as on 80 until now. Was going to post it, but I believe there are no reason for posting it just for mining but then there been several posts about 3.0.8 that Relic of Ulduar will become trade able and not soulbound. Thanks of course to the people giving the info about the relics.
So the good part is that this mine is very small but got TONS of saronite. Have seen up to 5 nodes at the same time in this very small mine, I've also got a few Titanium nodes as well so you get a lot of money just from the leveling. But then theres plenty of mobs here, and you pretty much get relics from 2/3 mobs.
What makes it even better is that there is a viking among all vikings in a cut-out hole in the stone wall where you get a quest, just complete the approx. 3 quests that are all done in this very small mine, after the quest where you turn into a viking yourself and do a quest for another special viking in there you will become automatically a viking when you enter the area which makes ALL mobs in there neutral so you will never get mobs on you if you don't want too.
And for the herbalists, there sometimes spawn icethorn as well here.
Here is a map:
