This Ghost Iron Ore farming guide will show you the best places for mining Ghost Iron Ore. There are two types of Ghost Iron Deposit, one of them is the normal Ghost Iron Deposit and there is also Rich Ghost Iron Deposit. The only difference is that you get more ore from mining Rich Ghost Iron Deposit.
I must also mention that Trillium Veins are rare spawn of Ghost Iron Deposits.
Ghost Iron Ore
Valley of the Four Winds
Valley of the Four Winds is the best place to farm Ghost Iron Ore, but sometimes it can get a bit busy because of the Tiller daily quests.
Jade Forest is also a great place to farm.
Townlong Steppes is another great place, there is usually very few people farming in this zone.
