Cobalt/Gowganda Area, Silver, Polybasite, Safflorite

These are special specimens. They are "old" meaning that they were collected before 1914 from the actual active mining operations. All are slices from a large specimen showing safflorite-coated silver with lots of polybasite crystals. The material was naturally near-surface oxidized mineralization and there is no calcite remaining. Beautiful macroscopic dendritic silver and beautiful polybasite crystals on safflorite under the loupe or microscope.

  • Rich silver high-grade showing lots of silver veinlets cutting through massive arsenides that look like, mostly, safflorite. There are cavities in the arsenides that contain platy native silver plus small wires of silver. Rich!

  • This is a slice of near-surface high grade where all of the carbonates have been leached away leaving open spaces in the arsenides that have leafy silver and, occasionally, very nice wire silver. The wires are all very small but look great under the microscope. The majority of the silver is composed of veinlets of varying thickness cutting through the arsenides. Wow!
