This piece was found around January of 2008, and is one of the more eye-catching Silvers from Porco that I have seen. It features a fine, good sized wire flaring out of a Sphalerite and Pyrite matrix. This is a great miniature specimen from a classic Bolivian locality. 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. This is why it is so difficult to obtain any good Silvers from Porco.
