What spells are available to find where an object came from?

Ichabod the Inscrutable is a powerful Wizard, and has found an unmarked, adamantine ingot. He would like to locate where it came from or where it was mined at. He has access to all non-UA, published Wizard spells, but doesn’t want to use a Wish. Additionally, his philanthropic endeavors have made him well liked at all the local temples, so he can reliably access any Cleric spell.

He’s already tried Locate Object, but the range on the spell was FAR too short for a location that could easily be half a continent away.

What are the spells, other than Wish, that can help him find where this ingot came from?
