  • 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!

  • Trethewey Mine
  • Cobalt
    Ontario, Canada
  • The Trethewey Mine was one of the first mines discovered in the Cobalt Mining Camp in the spring of 1904. At that time, William Trethewey travelled from western Canada to be in the area as soon after the snow melted and as prospecting was possible in the bush. All of the silver finds up to that time has been east of the railway right of way. He thought that there should be silver north and west of the right of way, as well and he was right! He discovered the veins that became the Trethewey Mine, as well as others that became the Coniagas Mine. These specimens are all slices of high grade from the Trethewey Mine that are composed of rich silver veining, laced through dolomite and nickeline. The nickeline shows some of the lobular structure often seen in specimens from this famous locality. Donated to a museum in 1914.
