Is it possible to do that? Not sure, but if you use a low level pickaxe in vanilla minecraft, it will yield nothing, when you break a high level material. So something is checked, when breaking a block.

Probably, a mod can change this function. So, if you add a flag to the ore block "placed by the mod = true" and check it while breaking it, it should work.
