It is possible that the Lost Dutchman mine is one of those 17 named mines of Tayopa as well, perhaps it was the Remedios or Virgin?
Usually with lost mines, the area where most treasure hunters have been searching, is the right area. Most of the treasure hunters hunting for El Naranjal look in Sinaloa and Durango. Lost mines are scattered all over Mexico and the US (and Canada and South America too) it is not a case that all of them are "funneled" into one spot.
The way I see it, why not go ahead and start mining this Naranjal of Don Jose' and see what the ore looks like? Perhaps the ore will help tilt the balance for his argument? Or perhaps he won't give a flying crap because he will be so rich?
Actually Shortfinger amigo your post sounds a bit like more 'shoe-fitting' to try to
make it fit. Could be, possibly, could be &c. Also I would point out that there are no Jesuits or Franciscans or Dominicans or any other priestly Order involved in the story of El Naranjal,
just a wealthy landowner. Of course there was a small chapel at the hacienda, likely for his workers and family, but the mine was not among the Jesuits numerous holdings as far as I could determine. There is no mention of it by Nentvig for instance, yet he does mention Teopira and other mines closely associated with the Jesuits.
NO donkey excretions, coffee?
