True Iron Ore Farming Guide Best places to farm True Iron Ore

True Iron Ore Farming Guide Best places to farm True Iron Ore

True Iron Ore Frostfire Ridge. Frostfire Ridge is my favorite place to farm True Iron Ore because it's a lowlevel zone and you can mine most ore without having to kill any mobs. Talador. Talador is also really good, but it's a higher level zone, so lower level players should stick to Shadowmoon or Frostfire.
