It's undeniable some of srge's images were taken at the mine during the investors tour.
Was there ever a real "investors' tour"? Or did MoMo just make a trip to Guadalajara to see his "Mexican lawyer"?
Generally speaking, when a group of people take a trip, they also take group photos. Not in this case. The only shots we have of what may (or may not) be "tourists" are two women in a tunnel. Seen from the back only.
Plus some miscellaneous machinery and some office interiors.
There's nothing in any of that suggesting "investors" every went on a "tour". MoMo claims he met "Johnston". If so, why didn't the whole "group" meet him? Why no photos of all of them together.
