Just finished listening to Bruce and I am rather happy with unconventional approach for several reasons:
1/ He has open mind/ lateral thinking abilities and "knows what he does not know"... unlike some "experts geologists" which led me to a huge losses by over spending my money eg looking for 4.5 mln oz which "Chinese miners ill equipped and without current High Technology/pumps etc" left below the water table, and they will find them "no problem"...
The Chinese were much smarter ... left nothing for "experts" who left me as a shareholder high and dry... minus LOTS of money... they got a job elsewhere and still drilling... I only remember the name to avoid investing with this "expert" again)
2/ There is a strong top 20 (min 65%?) and the management holding is substantial ! and I only invest in companies where the management hold substantial amount of shares...
3/ I have been successful with some companies run or influenced by experienced geologist like Ed Eshuy of DEG fame but also run by accountants, corporate/finance experts and entrepreneurs (eg Bill Beament was formally a geologist but rather entrepreneur and he created the NST success through acquisitions not organic growth/drilling)
4/ importantly Bruce has open mind, thinking logically and whoever is needed to progress to development ... will be hired IMHO
Some examples of experience in case of some companies I was v. successful as a L/T shareholder in the past:
