Sean even mentioned the name of the chemist / metallurgist.
Another red flag. Why send samples to some guy (Dr. DeMenna?) Why send samples to Germany?
There are many, many competent, legitimate labs that can easily assay any sample for gold and PGMs. Why not send a few to a main-stream, credible lab? There are several in Idaho that can easily handle anything that is sent to them. Yeah, I guess that's boring but.....claiming that only certain obscure labs in far-off places can do the assays sets of alarms in my mind.
