13-12-2020· The great silver (and tin veins) of Bolivia's Eastern Cordillera are the richest of both metals on the world. The "red mountain" is still producing silver, tin, zinc, lead, and other metals. The silver rich veins of the "Cerro Rico" are about a meter wide on average and the vines dive steeply into the mountain from the surface.
The Cerro Rico de Potosi tin/silver ore deposit was discovered in 1545, and is located immediately to the south of the town of Potosi, ~425 km SE of La Paz, just to the east of the Altiplano of Bolivia (#Location: 19° 37' 8"S, 65° 44' 57"W). Since 1545 it has been exploited primarily for silver, although tin has become the more important ore metal over the last century.

The Andean tin-tungsten-silver belt comprises an arcuate interval of some 2 000 km, extending from the Peruvian border through south western Bolivia into northern Argentina. Within this, there is a broad metal zoning from north to south of tungsten to tin-tungsten to tin, with variable quantities of silver. This belt embraces the legendary tin and silver mines of Potosi and Oruro.
