Hola Regin: Real de Tayopa is the name of a lost Jesuit mine which I found. Yes, I live in Alamos, Sonora. Sorry, I have no information on Pacho villa, other then when he was killed, his wife Luz was a a pauper. The gov;'t gave her a pension.
As far as I know you may hunt tesores freely. If it is on private landm the owner has 50%, if you have a previous agreement. If you don't hve a previous arangement with the land owner he gets 100%,
All artifacts go to the gov't. They will cross check, if they have better ones they will return the artifact, If they keep it, they pay you the market value.
LIsten to your wife, Mexico is loaded. The present period is the longest that she has had peace. Most areas, until recently, had no banks so it was simply hidden.
Ask away my friend.
