From the new find in November 2004. Andorite is lead, silver, antimony sulfosalt and was named for the Hungarian mineral collector Andor von Semsey (1833-1923), who holds a remarkable distinction for having two mineral species named after him (andorite and semseyite). This mine at Oruro dates Spanish mining as far back as the year 1595 and was mined by Incan Indians for several centuries prior. In all the years of mining, these are undoubtedly, the worlds finest Andorites extant. These specimens were extracted from the same vein system worked by the father of Bolivian mineralogy, Federico Ahlfeld. Ahlfeld worked the San Jose mine and Itos mine (the other significant andorite locality at the same mountain in Oruro) when the mines were used predominantly as a major sources of tin to the United States during WWII. The best examples of the species have come from Bolivia. This specimen consists of layered, steel-grey, lustrous crystals of the rare lead, silver, antimony sulfosalt Andorite. The piece is associated with minor prismatic Zinkenite and yellow-brown color Cervantite. I'm told that the part of the mine which produced these specimens is finished.
