Although Cobalt was famous for the vast quantities of silver mined there over many decades, many other minerals, some fairly rare, have been found there in impressive specimens, confirmed by electron microprobe analysis. Here are some.

- Nipissing 73 Mine
- Cobalt

- This is an interesting, different one! Very elongated lobes of nickeline are coated with silver-grey safflorite crystals. The lobes are mostly safflorite but have narrow, hollow interiors that may have been filled with silver or some other mineral, at some time. The nickeline would then be some sort of pseudomorph. Looks great, anyway!
