Well I am not on your server, But on the 2 PvP servers i play on 1kN = Death for alliance, I know I have seen some level 60's let 35-45 alliance though their, because ya have to once to get the flight path, but if they catch ya poking arround, gank fest, that area is realy horde land, and alliance just dont belong their. Once again I am not on your server, but here is my outlook.
The highlands, just north of the point is a cave full of ogers, lots o iron their but i dont know it is on your server, it may be too much of a gank fest.
Wetlands, not a lot of iron, but i am pretty sure i have seen a few nodes spawn, and like the oppsite of 1KN this is a pretty well defended alliance terrtiory.
Decolace, I see lots of mith, but every now and then.... Iron. Most of the zone is free of aybody , much less horde, cept the folks going to muldron.
Stonetallon? dont know how it looks on your server but the chared vale has mith and iron just north of it.
The badlands worth a shot, I say go early in the moring or late at night, when the horde are asleep, or at least hope for it.
