Brecciated zinc-tin-silver veins occupying fissures in normal faults. This mine, still in production, is located on part of the same 10km-long vein system as the better-known Santa Cruz mine (type locality of cylindrite). Mined for silver in Spanish colonial times, although no discrete silver minerals are known from here; silver is however present in several sulphosalts, eg: up to 1% in franckeite, 0.5% in cylindrite, 0.45% in jamesonite, with ore sampling in the 1930s showing 1.38% Sn, 0.18% Ag (Ahlfeld and Schneider-Scherbina, 1964).
