One possible reason for seeing no evidence of family buying is that this deal appears to be a very private matter in many ways, between Mr. H. and SAX. I would also like to think that Sumarium board members don't make a habit of blabbing to all their friends and relatives about money making opportunities. Any company that did so I'm sure would lose credibility quickly. Reading their webpage, Sumarium seems to be an upright and honest company. Their BOD is very impressive. They are one of the reasons I invested in the first place after doing my dd.
One other point. The following extract from SAX's latest news release indicates a clear invitation for Mr. H to validate his offer.
"and such confusion was never clarified by Samarium Group."
