Timiskaming- Gowganda
Cobalt, Ontario, Canada


Wonderful crystalline Silver slab specimen from the historic, Castle Mine in Cobalt-Gowganda, Ontario, Canada.  Specimen exhibits a spider web-like display of Native Silver in a Greenstone matrix.  Minor Calcite is also present. Shows brilliant silvery metallic luster. Only one side has been cut with a Diamond saw, the other side is "as found".  There may be Cobalt minerals also present. This specimen comes from an old 1900s 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. The Castle Mine was in production from 1917 to 1989 and now is currently being explored again and new high grade Silver veins have been discovered.  Today only a few countries have historically produced Native Silver, and even less currently are producing now.
