Very few mines in the world ever produced gold continuously for morethan one hundred years. The Homestake Mine was one that did, producing 40million ounces of gold from 1876 through 2001, when the quest for the yellowmetal was brought to an end for good. Over the next few years after the minewas shut down, tens of thousands of ounces in additional gold were recoveredas mine facilities were systematically decommissioned, and the mill site wasreclaimed and converted to an open-air museum.For more than 125 years, the Homestake Mine helped support thelivelihoods of countless numbers of people who were directly or indirectlyaffiliated with the mine.

This living legacy continues to evolve with thetransformation of the mine into a deep underground science and engineeringlaboratory.The Homestake legacy began to unfold in August and September 1875when the Bryant, Blanchard, Smith, Gay, and Lardner parties discovered richgold placers in Deadwood Gulch. What they found was mostly Homestake gold,weathered and worn to nuggets and dust. Fred and Moses Manuel, alongwith their partners, Henry C.

On April 9, 1876, MosesManuel and Hank Harney discovered a rich quartz outcrop upon which all fourmen located the Homestake lode claim.The Black Hills was still a part of the Great Sioux Reservation then, pursuantto the Fort Laramie treaties of 1851 and 1868.
