Hello everyone! Since I'm a big fan of gathering and it is a important point in the game I decide to run through all regions and see which materials can be found. I found the achievement descriptions to general. So here we go with the first map:
Ostgarath - The pictures show in which specific region u can find what. The placement of the materials itself is not important - just green marked area where it is in.
I hope this will help you guys and I try to finish this by time!
