BG has 2 separate threads on item drop zones/mobs. The 1st one is on the Dat Mining Discussion thread (http://www.bluegartr.com/threads/108...mber-14th-2011 - page 7 onward has mobs/zones throughout) and 2nd one is on the new thread (http://www.bluegartr.com/threads/108...ne-Info-Please).

Personally, I've done (with THF):
- Seasoning Stone (decent drop rate) from Fei'Yin (bats)
- Seasoning Stone (high drop rate) and Fossil Bone from Kuftal Tunnel (worms + tigers)
- Seasoning Stone (high drop rate) and Fossil Fang from Gustav Tunnel (worms + turtles)

I know many ppl who tried both CN and GC and got nothing after 40-50 mobs and haven't heard anyone has gotten any of the 3 items from there so it's most likely not available from those zones.
