Very nice example of silver mineralization in Nipissing diabase. The specimen shows a vein of silver and arsenides cutting through diabase with re-mobilized silver streaking off in tension fracture veinlets perpendicular to the silver arsenide vein. Sawn on one side, rough on the other. Some of the vein silver shows good dendritic structure. Really nice piece!
