Soft, sectile mass of Acanthite with many crude forms of cubic crystals. The cluster at the tip is 7mm across. The specimen comes from the historic cobalt/silver Keeley-Frontier mine located in one of the largest silver mining districts in the world. The mine produced an incredible 3.3 million pounds of cobalt and 19.1 million ounce of silver. There is associated Calcite in mass and as crystals, a clear indication that the specimen was never etched.
