High-grade silver ore from the Mammoth Mine near Gilbert, Esmeralda County, Nevada, approx 65 x 65 x 50 mm. Massive white and clear quartz specimen with spots and specks of dark, silvery-grey mineralization, probably argentite or pyrargyrite. The Gilbert Mining District is located between Coaldale and Tonopah north of US-6/US-95. It was active from the 1890’s at the Carrie mine which produced small amounts of lead and silver. Limited production of gold began in 1924 from shallow underground mining on the Last Hope, Black Mammoth and Monte Cristo vein structures. Exploration in the early 1970’s focused on porphyry copper mineralization which then led to the discovery of open-pit minable gold in the early 1980’s. By 1988, Kincaid Exploration and Mining Co (Kemco) began a heap leach operation mining from the McLean Pit. Hecla acquired the Monte Cristo property in 2012.
