Cobalt/Gowganda Area, Ontario -Glacial Float Silver Specimens

When giant ice sheets and glaciers covered the Cobalt area prior to 10,000 years ago, they moved over the surface of the land ripping chunks of rock and silver mineralization from the silver veins. These specimens are examples of some of this material. As you can see, the arsenides and calcite have been etched away, naturally, ove rthe millennia. They can be found today in the earth, south of Cobalt, with metal detectors. Hard work! They are rare!

  • A specimen of pretty-well solid silver with a little attached rock, erythrite nad some relict arsenides and a bit of what looks like bornite or tetrahedrite. Very good example of glacially transported and deposited silver vein material.

  • A large mass of spongy native silver. For some reason, the Nipissing Mine had a lot of spongy silver strewn about the surface, near the veins. The silver was probably removed from the veins by gravity and ice over the millennia and the carbonates and much of the arsenides naturally etched away to reveal the silver. Impressive! r
