Two problems your argument does not address:
1. Lumb & Lowenthal, and their track record of scams and failure. Lumb has already scammed his way out of both the South Africa and the U.K. stock markets. Tellingly, in the U.K., he was running mining stock scams. The other "sisters" in the USA (FFGO, RENS, HGLC, Nationsmark, SJCH), all have Lumb connections and Lowenthal was involved in NMGL, FFGO, GNCP, HGLC, and RENS. All supposedly "mining stocks," none have produces one dollar's worth of gold, or silver, or copper, or sand.
2. Parkinson is the "go-to" geologist for scammers, or was until he had his qualifications jerked by various states. His approach to a mining report is clearly "the report will say whatever the people paying me want it to say." Do you really think it was chance that a couple of people whose companies always failed, hooked up with a crooked geologist?
