Cobalt/Gowganda Area, Ontario -Silver Specimens

The Cobalt mining camp has been the source of incredible amounts of silver over the past century. The ore was, for the most part, native silver associated with cobalt-nickel and iron arsenides and antimonides. Over 600 million ounces have been produced from this amazing place. Here are a number of specimens of silver from Cobalt and the relatively nearby Gowganda.

  • Interesting mineralogical texture here! This piece shows relatively large crystal sections of arsenopyrite thickly embedded in both calcite and wall rock. Of course there is lots of native silver in between the arsenopyrite crystals and in a peculiar line that runs diagonally through the specimen. Rough one side and sawn on the other so that you can see mineralogical texture from two perspectives. Nice!

  • A heavy specimen of silver in arsenides, sliced on one side to reveal the mineralization texture. Some of the silver is dendritic while some of it is in veinlets, apparently remobilized out of the arsenides. Rich!

  • Exquisite dendritic silver is laced through the dolomite in this high grade. Beautiful dendrites up to 18mm or so are associated with a small amount of arsenide mineralization. Really nice!

  • This is a heavy vein section that has had most of the calcite removed to reveal a thick plate of calcite on both side of the vein. The top one is the thickest. The arsenides have not been analysed but appear to be, probably safflorite and skutterudite, although there appear to be others in the mix. Native silver is laced through the arsenides. Rich! Displays well!

  • This slice of super-high grade silver mineralization shows a little associated dolomite and dark-grey arsenide. The silver is present as fine dendritic crystals, thick solid silver, in the center of the vein and veinlets cutting here and there. Really amazing high grade from the old days. Looks super!

  • A rather astonishing example of high grade silver-arsenide mineralization, mostly silver! It is a thick slize of high grade showing lots of fine dendritic silver formations along with just solid silver and veinlets. Amazing! From one of the largest concentrated areas of of silver in the world!

  • This si a fragment of chalcite that has veinlets of silver cutting through it. It is an old piece and the silver leaves are tarnished black. The top of the specimen is an arsenide vein consisting of nickeline and a coupel of other more silvery arsenides. The old, antique label that accompanies it says "Glaucodot" but I don't know if that it true. Glaucodot is pretty rare at Cobalt and that may have been a fanciful determination by an early geologist or collector at Cobalt. There is one unusual arsenide in the vein, very dark with conchoidal fracture. It has not been analysed. An oldie!
