Mining 326-350 - Adamantite
Horde and AllianceNagrand
From 325-350 continue mining Fel Iron when possible but begin to look for the non-rich adamantite veins which become available for mining at skill 325. The best adamantite mining zone is Nagrand where almost anywhere you look in the zone you can find adamantite veins. Start by performing a full-circuit as shown below and then move into the inner water areas if those are camped or you prefer a change while leveling.Mining 351-400 Cobalt / Rich Cobalt
Remember you must be at least 350 to start mining the regular cobalt nodes, the rich cobalt requires 375 mining. You can actually take Rich Cobalt to 450 for leveling if you wanted to (just like Fel Iron in Hellfire Peninsula for TBC) but just to pretend like you need to go outside of the first zone in The Wrath of the Lich King to max your mining we will put up more zones and have you mine the other minerals for leveling. But keep in mind you do not have to leave these zones. The first leveling map is for Howling Fjord, it's pretty simple to follow, just remember the lines that go over caves want you to follow the line from inside the cave and not outside. You can also use this gold farming guide to buy cobalt ore to smelt which gets you from 351-375.Mining 376-400 Rich Cobalt in Zul'Drak
There will be more Rich Cobalt Nodes in Zul'Drak if you are interested in leveling your skill beyond 400 on Rich Cobalt.Mining 401-450 Saronite / Rich Saronite
You must be 425 to mine Rich Saraonite, you will find Titanium Veins along the way but you must be 450 to mine Titanium. Sholazar Basin is a miner's heaven due to it's structure and it's very easy to follow the zone guide for leveling. This zone will probably be overcrowded when WOTLK first comes out so I've included a lot of different areas on this map you can farm. If you could get one of the Pillar's to yourself you could farm / kill mobs for exp while working mining up. Otherwise you can see that the main ridge around the zone is the hotspot for mining titanium and saronite, as well as, all of the pillars and streams/lakes connecting them.If you are looking for a guide specifically on Titanium Nodes because you want to learn how to make money farming titanium the above map is just that. Titanium spawns in place of Saronite Nodes so if you follow the above map while leveling mining you will find Titanium Nodes. You have to be 450 to mine Titanium. Some people have said that the inner circle of Icecrown is good for Titanium, as well as, the areas in Lake Wintergrasp (but are heavily farmed). Where there is Saronite, especially Rich Saronite, there will be Titanium. It's that simple! There are also places in The Storm Peaks that also have titanium, the caves especially.
