Gold Recovery at Homestake Mine: The Last Pour - 2002

Homestake Gold Mine was the longest operating mine in North America. The way it operated was a feat of engineering. Richard Blackstone was hired as a civil engineer to build railroads for the mine, but that soon developed into revolutionizing hydro power. Edison and Hearst were paying attention to the Black Hills of South Dakota because of the ingenuity of Blackstone. @adams1920 | Micro Film Series

In South Dakota, the historic Homestake Mine once produced gold valued at over $1.5 billion. Its deep shafts now host the Sanford Lab, where researchers use the dense rock to shield experiments. This site remains a pinnacle of American engineering, blending mining heritage with modern physics. #SouthDakota #HomestakeMine #GoldHistory #MiningEngineering | Erna Mulyani
