the Casey PromotionI just received some promotional material from Casey Research. Lots of talk about "sulphides"... However, looking at the core photo they sent out, I did not discern any chalcopyrite (Cu sulphide) or pentlandite "eyes"(Nickel sulphide) ...Looks mainly like pyrrhotite (Fe sulphide) to me..... Buyer beware until assays are received! good luck to y'all..
