The Homestake claim was founded on April 9, 1876 by Fred and Moses Manuel and Hank Harney in Lead, South Dakota. They soon sold their interests to a group of men, led by George Hearst. Under Hearst's direction, the Homestake Mining Company was incorporated in November 1877 and grew into the major economic driving force of the Black Hills area and one of the most prominent gold mines in the country. The mine was in continuous operation until 2001, and was later converted into the Sanford Underground Laboratory.
