Can a Griege minion with Burrow evolve, and can it burrow onto a source well?
One reply gives this reading; no official ruling was given.

It can evolve, but if it uses Burrow it must promote on its next turn. It cannot burrow onto a source well, because a source well is not a non-path hex, and its talents are inactive while it evolves.
