Peacock ore is bornite, a copper sulfide. Most of the samples sold to mineral collectors are really chemically treated chalcopyrite, which has been exposed to acid causing the colorful array. That would be strongly magnetic.

@Weasel, your comment about acid-treated chalcopyrite is correct. However, you are incorrect about the magnetic part. Acid-treated chalcopyrite is not magnetic.
