Description
A super piece of RARE vanadium-sulfosalt Patronite from the TYPE LOCALITY, the Ragra Mine (Minasragra) of Huayllay District in Pasco Province. Here we have dull but metallic masses as a rich ore specimen with an old label. Patronite was named in honor of Antenor Rizo-Patrona (1866–1948) metallurgist of the Huaraucaca smelter, who discovered the ore.
