Mining

Couldn't find a really good place to post this due to Jewelcrafting not being available yet. However, for you miners planning on doing Jewelcrafting OR selling minerals....here is a list of items you can use to collect and sell or collect and level up your Jewelcrafting to 300 when BC comes out. (This was given to me from a friend in the Beta)

With Artisan-level mining, you can harvest ore from the following mineral veins: http://www.wowhead.com/?objects=-4&filter=cr=7;crs=4;crv=300

Note that Incendicite (http://www.wowhead.com/?object=1610), Lesser Bloodstone (http://www.wowhead.com/?object=2653 ), and Indurium (http://www.wowhead.com/?object=19903) are quest-related veins.

With gathering professions now comes new passive and cast abilities. Mining now gives you the passive ability "Toughness". With each rank up in Mining, you obtain a new rank in this skill.

Here are the different ranks for this ability in order of ranks and Mining skill:
