Acanthite is a primary ore of Silver. However, 75 percent of Silver is produced as a byproduct or co-product of copper, zinc, or lead ores. In this case, the specimen here consist of both small portions of Acanthite intermixed with a much greater amount argentiferous Galena, an ore of lead containing Silver.

Alpersite was approved in 2003, but I haven't seen too many specimens of this mineral. It is a Mg-Cu sulfate and is post-mine. There are tiny crystals formless to tabular crystals less than 1mm and sugary aggregates. On this specimen there is also white, fibrous Pickeringite. This is the type and only locality. The lot that I have was verified by XRD.
