NB: The Animas, Siete Suyos, Oploca, and Chocaya mines all worked the same system of veins and have very similar mineralogies. For this reason it is generally impossible to tell which mine a specimen actually came from, and "errors" are common both on collectors' labels as well as in the scientific literature, so many collectors just refer to it generically as the "Chocaya-Animas" mine.
