[QUOTE="Village, post: 52022, member: 1900"] hey guys like I said I could be wrong, most definitely. From a photo your working by colour and at best what the texture might be, little lone doing any sort of confirmation testing, even basic hardness and streak testing. It may well be mica schist and limonite, limonite is a mineral based hydrated iron hydroxides and will some colour variation is possible, but under a streak test, it will illustrate its primary colour being brownish yellow or orange brown. It is in fact an oxide. On the Platinum issue, it is the only mineral that would fit photo, being cubic and known to erode commonly out of the host rock. Again I could be wrong. [/QUOTE]
