Property History:
The Vallecillo mines, located in the southwest portion of the Providencia property, were originally worked by Spanish colonizers who apparently abandoned operations due to a combination of water problems and "constant incursions" by local peoples. The Vallecillo Silver Mining Company of New York bought the deposits in 1851. That company began operations at the old Jesus Maria mine, but water problems forced them to move about four kilometers to the east, to another Spanish-era operation, the Delores shaft.

By 1885 there were four shafts and an incline at the bottom of one of the shafts at Vallecillo within a distance of about 400 meters along the vein. The main working was the 150 meter deep Santiago shaft. Two other shafts had been sunk further to the west of this area, bringing the total known surface extent of the vein to approximately 500 meters. The Spanish had mined to a depth of about 50 meters and, as of 1885, mining had been done on five levels to a depth of about 120 meters. Workings had been developed to about 550 meters to the west, and 360 meters to the east of the Santiago shaft. It is unclear when production at Vallecillo ended.
