Next, I go all the way South to Zeth’gor (68,73) then to the Expedition Armory (55,77). At (60,50) I turn North and go to Forge Camp: Rage and Forge Camp: Mageddon, always 3-4 nodes at these camps. Usually, I take the following route: I start at the Hellfire Basin (50,52) and follow the Path of Glory, East, zigzagging through the orc camps on both sides. Start doing laps and gather all the Fel Iron Ore that you can find. Or, use the portal in Orgrimmar or Stormwind City to teleport to Blasted Lands, and then go through the Dark Portal there into Hellfire Peninsula. Teleport to Shattrath City in Terokkar Forest, then fly to Honor Hold (55,64) if you play Alliance, or to Thrallmar (55,39) if you’re Horde. Here’s a good mining route for Fel Iron, in Hellfire Peninsula.

Even though you can stash up this metal while it’s cheap, at AH, in order to sell it when the price rises, you can still make 100% of profit with it, if you gather it yourself.

At times, the price on Fel Iron Ore and Adamantite Ore can spike, reaching up to 150g / stack.
