Magnesium is typically an additive - used in the detergent package. I have not seen any Mobil 1 analytical results for awhile so I do not recall specifically what their additive package profile looks like.
The copper seems a little high to me, but I would not worry too much at this point. I have been told that some companies even add a little copper, but I have not verified that statement.
My iron has always been in the 30-40 range, no matter what oil, so yours looks fine.
