gollum , i hate to say it but this is another legend with somewhat mirrorerd facts to the parts of the tayopa and LDM legends , a box in a shaft or tunnle or crypt ...jewiery vs maps or chruch records ...i find it interesting that you stated :
"this is the site of the Virgen de Guadalupe Mine from the Mission of Tumacacori."
i see a pattern in the confusion , note that kino was directly realed Tumacacori as well as a unknown jesuit related to the tayopa massacre site acount . my piont is all three legends fit togather yet not the way one would think they could ....
look at the similarities between these legends
Virgen de Guadalupe
Guadalupe de Tayopa
Guadalupe de Santa Ana
i think he has the name miss writtern
it should be Guadalupe de Virgen
i had to go check but (our lady of Guadalupe) is also called (the virgen of Guadalupe ) maybe this is why it is backwards ....
what proff dose he have that it is in fact the (virgen of Guadalupe mine )


??
the reason i ask is this could very well be one of the 18 tayopa mines ....
the reason i say that is there was another name for the Lady of Guadalupe . (Lupita) the event took place in december 9th 1531 ---december 12th 1531,....... the event centerd around the 10th and the 11th , so the event lasted 4 days ....
this same code was used once before this and i do know what it means ....
