Hey guys, before I get started, I'd just like to recommend that this is quickly moved to the contributors section, as I've been using this trick for a while and have no desire to see it hotfixed by Blizzard.
Easy Mining in Ulduar (Infinite Pure Saronite)
It's an extremely simple trick, and I'll upload photos when the weekend rolls around if some users need them.
NOTE: ROGUE/DRUID REQUIRED
(Mage probably could too, or an invisbility pot might work, will experiment later)
First, you must gain access to General Vezax in the new raid instance Ulduar.
General Vezax - WoWWiki - Your guide to the World of Warcraft
You can do so by killing the four watchers.
You'll notice plenty of Pure Saronite ore scattered around the area.
(Object: Pure Saronite Deposit - Thottbot: World of Warcraft)
It's possible to reach these nodes by stealthing by the mobs.
Hug the walls when possible, and be patient.
The Pure Saronite ores drop quite a few gems, and are a real profit cruncher once you get in the habit of doing so.
When you're done mining, perform a soft reset.
The term "soft reset" can also mean having all party/raid members leave the instance for at least 30 minutes. This causes any trash mobs that have been killed to respawn. The most common reason to do this (deliberately) is to reset a boss fight that bugged out part way through the encounter.

Thanks for your time!

Note: This is BANNABLE, and although I have yet to recieve any warnings from Blizzard after doing this for a week, I'm sure that it could happen to others (Thanks to Sychotix for pointing this out)
