Produced 800 tons of tungstite/hydrotungstite as ore (!) during World War I. Now completely worked out and not even traces of those minerals remain. It is only 12 km from the large Colquiri tin-zinc mine, which lies across the state line in La Paz department, which has lead to some garbled locality labels.
Sometimes given only as the "Calacalani mine" or "San Antonio mine", leading to the additional erroneous assumption that two localities are involved.

Note on the mineral list:

"Hydrotungstite" specimens from here have now generally dehydrated to tungstite pseudomorphs after hydrotungstite.
