World of Warcraft farming Embersilk Cloth

This place is located in Deepholm near the big hole, not sure what it is called. Be sure to use the treasure finding potion which most servers sell them for 150-300g each. I farmed for 20 minutes and got:
372 Embersilk Cloth
7 Greens
2 Pyrite
7 Water
10 Elementium 
10 Volatile life
12 Volatile Air
5 Volatile Earth
9 Volatile Fire
