A very small mine worked for silver (mainly the mineral eucairite) during the 1880s. By the time the workings had reached a mere 8 meters deep, they had already yielded 115 kg of silver. By 1889, when Klockmann received the specimens from which he described the new species umangite, labelled as being from the "Sarmiento vein" (which Guerrero, based on old 19th-century correspondence, equated with Las Asperezas), the workings had reached 14 meters deep, where a 35 cm wide vein was comprised of 50% eucairite. Therefore most likely this mine is the true type locality for umangite.
