My dad was telling me a story about his youth in 1982 when he was 18 years old. He was part of a mining company based in the US who owned claims that used to be a part of the ancient Jesuit tayopa mines located in Northern Mexico. To his knowledge there are 17 silver mines and 3 gold mines. I was curious if this was the same Tayopa that I have read about. He lived on-site for 3 years and has good understanding of the Tayopa ruins.
