This specimen is a very rich example of dendritic silver in high grade ore from the Cobalt camp. It shows rich, dendritic silver, associated with cobalt arsenides (a little erythrite present) in carbonate vein matrix, with chloritized wall contact on the rough side. Some knobbly silver protrudes on the rough side, as well. Sawn on one side to better reveal the mineralogical textures. Excellent!
