  • This is a slice of high-grade ore from near surface. The arsenides have been oxidized a little bit to the extent that there is some fibrous, primary erythrite on the piece. It has a very nice dendritic pattern to it. Safflorite was determined by x-ray diffraction. Nice piece!

  • A thick slice of silver ore that is mostly....silver! This piece is representative of the highest grade ore that occurred at Cobalt. Veins of solid silver. This is an old timer that was mined, probably, back in the 1910's. Exceptional!

  • A slice of spectacular, high-grade silver ore that is mostly..... native silver with a little arsenides and carbonate. This type of high grade native silver is representative of the finest, richest ores that were encountered at Cobalt. Spectacular!

  • Spectacular silver ore from one of the greatest silver mining camps in the world! The mineralization in this piece is mostly silver with just a little arsenides and carbonate associated. A slice from an old time piece of ore that I would guess was mined in the 1910's. Amazing!

  • Beaver Mine, 1600 foot level
  • Cobalt
    Ontario, Canada
  • A slice from a piece of a high grade vein from 1928. No oxidation or weathering because this piece was fresh from the operating mine way back then, not a modern day waste dump find. (Not that there is anything wrong with THEM, just sayin') Probably about 70% native silver by volume with the rest, mostly calcite with a relatively small amount of arsenide mineralization. The arsenide and carbonate mineralization appear to be brecciated in the silver. Amazing high grade!

  • A slice from a piece of a high grade vein from 1928. No oxidation or weathering because this piece was fresh from the operating mine way back then, not a modern day waste dump find. (Not that there is anything wrong with THEM, just sayin') Probably about 80% native silver by volume with the rest, mostly calcite with a relatively small amount of arsenide mineralization. The arsenide and carbonate mineralization appear to be brecciated in the silver and cemented by massive native silver and silver veinlets. Amazing high grade!
