Geography
With residences at 4340 m above sea level, it is the highest Argentinian year-round settlement. The locality of Chico Pairique, at 4340 m meters, (also located in the Province of Jujuy), is at higher elevations, but was considered by the National Census 1991 as dispersed rural community with little or no year-round residences at those altitudes. The population of the settlement at the mine ranges up to 673 inhabitants, though during initial construction, the region housed about 2000 inhabitants. There are two centers: one administrative (offices, laboratories, hospital, house and chapel) and another to the west about 7 miles where "The streak" and where most of the mines are located.
