Hemimorphite with Hydrozincite

Mined in May of 1980, this hard to find specimen features excellent, gemmy/translucent, silvery colored Hemimorphite crystal groups associated with very rare powder-white Hydrozincite from the world famous Sherman Mine in Leadville. One of the better association specimens of Hemimorphite from the Sherman Mine that we’ve ever seen. This locality is arguably the most productive specimen producer in Leadville, despite the fact that over 10 million ounces of Silver came out in a period lasting around 11 years (started 1968-1970 and reopened 1975-1982). The Leadville mining district was the most productive silver-mining region in Colorado. As of 1963 the cumulative production of the area was 240 million troy ounces of Silver = $6.6 billion at today’s prices. Ex. Richard A. Kosnar collection Specimen# CO712B57
