A group of silver and tin mines mined from Spanish colonial times up to the present. Numerous small mines and prospects in this district (e.g. Viboras) still produce specimens, and locality data on labels is usually unreliable, so it is often not possible to state precisely which mine in this district produced any specific specimen. Machacamarca was the first locality in the world for augelite CRYSTALS (type locality augelite was not well crystallized).
NB: Recent magnetite specimens being marketed from Bolivia, allegedly from this district, are wrongly labelled: The true locality is the San Calixto prospect on Mt. Huanaquino, roughly 20 km N of Potosi city. Specimens from other mines in the Machacamarca district are often labelled simply "Machacamarca".
