Has anyone found (and made a list) of where they drop?

I would hope stuff like "Ishgardian Steel Ingot" would drop somewhere in Stone Vigil (I haven't tested it) but it wouldn't be the first time an MMO didn't work like that, just look at chinchilla fur. It drops from a treasure hunt and not the mob @_@

so yeah. any help with this would be welcome!

edit: Ish steel ingot was an example... I'd like the entire known "drop location" list if possible (but thank you for confirming where the ingot drops)
