I think that there is some confusion in this article about the definition of what constituted treasure under the old Treasure Trove law. I believe the distinction was not between lost and deliberately deposited objects but hinged on whether there was an intent to recover (ie votive offerings or grave goods were deposited with no intention of recovery but hoards buried for safekeeping would have been intended for recovery). I do not have any reference to hand to confirm this but perhaps someone else could follow up and edit accordingly.
