Three small adits mined exclusively for vivianite specimens, located a few hundred meters downhill from the Canutillos mine (qv), to whose "Cooperativa" members it now belongs. Host rock is non-mineralized red argillaceous sandstone.

Note: This is NOT the locality for the recent abundant magnetite crystals from Potosi Department, an error on some dealers' labels - see Cerro Huañaquino locality.
