I've been slacking on leveling my team, but wanted 450 mining so I could be using/selling the titansteel cooldown every day. I boxed Utgarde Keep to get my mining up to 400, but farming Cobalt at 70 is pretty easy anyway. I originally didn't think it was possible to get to 450 until I was in the mid 70's to head to Sholozar, but I found easy Saronite nodes in Crystalsong Forest (see attachment.)
There are 7 spawn points, with up to 2 nodes up at a given time (I believe the 2 eastern-most nodes belong to the Icecrown spawn group.) I've gotten Saronite, Rich Saronite, and Titanium nodes. There are ZERO npcs anywhere near the wall there, so you could probably get to 450 mining even before level 70 (there's no level requirement to train gathering skills.) There are 2 or 3 level 76/77 worg between the wall and the Dalaran crysal, but they're easy enough to avoid.
I generally afk my miner here while I raid, and after 3 hours I end up with around 4-5 stacks of saronite ore, a half dozen gems, and a titanium bar or two.
