This one does actually exists. I have talked to the elders at the Jemez Pueblo and they would like to get it back. But as in a lot of things the information contained in this newspaper account is rather inaccurate. There were many mines in the mountains between the Jemez Pueblo on the west and the Cochiti Pueblo on the east in which the Indians were subjected to slavery to work in the mines. One such area, the Blanding district, was very rich, but was actually passed over by the Spanish because of the Telluric nature of the ores. South of there the ores are free milling. The southern end of Jemez contains many small but high grade ore bodies. On the west of the Jemez Mt's near Holy Ghost Springs gold bearing veins were found that ran $800 to $1000 in gold per ton. North of Cuba, NM, there are many veins of siliceous gold and silver that were mined primarily for smelter feed and paid well for their gold and silver content.
Somewhere in the Naciemento Mountains, east of Cuba, NM, the Dominician padres were transporting a large south to Mexico City during the Pueblo Revolt, when they were massacred by the Indians and the treasure buried. It is thought that it's approximately value today is $80,000,000 to $90,000,000. A lot of zeros. The Spanish also use to mine a great of copper east of Cuba.
It is a very interesting area.
