It would be useful to have some built in method for prospecting a chunk from the surface to see if it contained any bedrock ores, as finding them otherwise can be rather laborious. This would also be beneficial to a modpack that, for example, had bedrock ores as the only source of ore.

This is basically what Scannable is for; in fact, originally it would've almost been part of this mod, but then I decided to make it its own thing with a bunch more options :P
