Sulphide city areaCrescat 65 mentions it at ~1:04:30
The theory of the porphyry hub near Jackie is biting the dust. If you draw a line from Jackie through Sulphide city/Grizzly and keep following it you will eventually end up at the big "causative" intrusion to the NW. That is probably the source and if it is another huge Cu-Mo-Au porphyry deposit, more WOW!
It is a shame that all of this is being discovered at a time when investor interest in equitues and commodities is at a multi decade low.
