The Anaconda Copper Mine was a large copper mine in Butte, Montana. It was bought in 1881 by Marcus Daly from Michael Hickey. Hickey was a prospector and Union Civil War veteran, and named his claim the Anaconda Mine after reading Horace Greeley's Civil War account of how Ulysses S. Grant's forces had surrounded Robert E. Lee's forces "like an anaconda". Daly then developed the Anaconda Mine in partnership with George Hearst, father of William Randolph Hearst, and James Ben Ali Haggin and Lloyd Tevis of San Francisco.
