When Deathwing roasted Azeroth, he left fiery destruction in his wake. The volcanoes, tidal waves and rents in the crust thrust different metals to the surface, while melting others clean away.
I have now updated both my Mining charts, showing the post-Shattering zones where ores can now be mined, and my charts showing Gems from Mining and Prospecting.
The current versions were created using current spawn count stats from Wowhead. I plan to revisit the charts in a few weeks once the stats get a little more mature.
I hope you find the charts useful for leveling your Mining or Jewelcrafting!
