This piece came from a new find at Porco about 8 months ago (2009). It is to the best of my knowledge, the best piece from the find, and I have seen virtually every piece that came out. This piece is a superb and is one of the most unique Silver specimens I have seen from Bolivia. It is a great fine group of crystalline Silver with some pseudo-wires forming a very attractive, three dimensional, branching specimen. The piece is associated with sparkling, micro Quartz, and reddish-brown Sphalerite. The mine at Porco is the oldest and most significant Silver mine in Bolivia, and obtaining specimens is next to impossible because miners rarely bring out anything for sale, as the mine is a large commercial production, and virtually everything goes into the crusher. Most everything that evades the crusher is usually taken out of Bolivia by a geologist who has an "in" at the mine, or sometimes a group of brave miners risk losing their jobs by sneaking out a handful of specimens to raise a little extra money to feed their families. I obtained this piece directly from the miners at Porco a few months ago.
