NATIVE SILVER!!!!! 

  Crystalline  Silver specimen from the historic, Cobalt, Ontario, Canadian mines.  This specimen has been cut with a diamond saw to produce a .5 centimeter slab with both polished sides. Native Silver is hosted in Calcite matrix. Dendritic Silver exhibits brilliant silver metallic luster. There are other complex Silver Sulfides and Arsenide minerals also present.

This specimen comes from the  old, 1900s historic Silverfields  Mine, mine dump.   Massive Native Silver was discovered  in veins in Pre-Cambrian Greenstones in Cobalt Ontario in 1903 and hundreds of mines were eventually exploiting the metal. By 1915 the mines were essentially exhausted. Some minor mining occurred later.  Native Silver was found in several important American mining districts historically. Virginia City, Tonopah, Austin, and Rochester were the most productive Nevada mines. Today a few of these mines are still producing Silver...but not Native Silver. Moreover, only a few foreign countries still produce Silver and its very difficult to obtain any Native  specimens today. Weighs 7.4 OZ.
