WoW Gold Tips - Tip2 from Luke Brown:

Here is tip 2 for making a serious amount of gold. (Click here for Gold Secrets Guide Tip1 from the Luke Brown gold guide). Remember, there are over 200 pages of gold tips available at: Gold Secrets.

Dark Iron Mining- This is the gathering technique I routinely use to make 30-60 gold in an hour. Yes, you really can make that much gold using this system.

Dark iron is a very valuable material that is used to craft high-end items and also for reputation gains with the Thorium Brotherhood. Put simply, it is worth a lot of gold. It is only found in two places in the entire game, Blackrock Depths and Molten Core. Obviously, Molten Core is a 40 main raid instance so you can’t sneak in there to get ore. That leaves us with BRD.

Upon entering the BRD instance there is a door to your left. You will need to be able to lockpick it or you will need to have the Shadowforge key to open it (obtained by completing a quest inside BRD).

Once through there you can either walk straight ahead or turn right through another door. You want to walk straight ahead to the area called the Dark Iron Highway. In this area is where you are going to make tons of gold mining ore. (To see the full guide in full click here: Luke Brown Gold Guide).

There are numerous dark iron spawn points in this area and on each run you should be able to get to one or two of them. Simply mine the ore, leave and reset the instance to do it all over again. You will need a couple of people at least for this or if you are a rogue or druid you can stealth in. Also, hunters can run in and feign death to escape the mobs around the ore.
