The Anaconda Copper Mine was a large copper mine in Butte, Montana that closed operations in 1947 and was eventually consumed by the Berkeley Pit, a vast open-pit mine. Originally a silver mine, it was bought for $30,000 in 1881 by an Irish immigrant named Marcus Daly from Michael Hickey, a Civil War veteran, and co-owner Charles X. Larabie. From this beginning Daly, along with partners George Hearst, James Ben Ali Haggin and Lloyd Tevis, created the Anaconda Copper Mining Company, which ultimately became a global mining enterprise that would go on to mine 18 billion pounds of copper over 100 years. At the height of The Anaconda Copper Mining Company, it consisted of the Anaconda and other Butte mines, a smelter at Anaconda, Montana, processing plants in Great Falls, Montana, the American Brass Company, and many other properties spanning multiple countries.
