A stupendous slice of "old stock" high grade dendritic silver from one of the original mines at Cobalt. The vein was originally found in wilderness but the mine ended up being right in the Town of Cobalt after the rush was finished and the mines established. The Coniagas Mine had a unique name, indicating the elemens making up its ores = CoNiAgAs = Cobalt, Nickel, Silver, Arsenic. Super rich!
