Belle Fourche Dam

The Homestake Gold Mine, located in the northern Black Hills of South Dakota, is a historic site that has been a significant producer of gold for 126 years, yielding over 40 million ounces. Hosted in Precambrian rocks approximately two billion years old, the mine showcases a complex geological framework with various metamorphic rock types and intricate fold structures that contributed to its ore formation. Mining activities utilized an extensive infrastructure of shafts, winzes, and drifts, developed through a detailed understanding of the region's geology. The ore mineralization primarily resides within the Homestake Formation, characterized by pyrrhotite, arsenopyrite, and native gold, alongside a range of associated minerals, making it a prototype for iron formation-hosted gold deposits.
