| General | District record includes the mines discussed in Bailey and Everhart's PP-360: New Almaden, America, Providencia, Enriquita, San Antoniao, San Mateo. The "district" would also include the Guadalupe, Senator, Santa Teresa, and Bernal Mines, however these are likely not of the same deposit. |
