That makes no sense. If it can be created by kryptonian minerals and metals being destroyed than it would be created every time that planet got hit by an asteroid or had an earthquake or a volcano went off. If it comes from pieces of krptonian mass than it can be created every time you destroy the necessary elements from the planet's landmass.
Not to mention the movie isn't bound to follow any previous story told. I just want it believable somehow that this stuff lands on the same planet as Superman and I don't think a mere coincedence suffices. I also want an explanation is needed for how his enemies know it exists and how they know it would harm Superman. The explanation in STM by luthor is pure crap covered in cheese.
