Holy Terror Mine, Keystone Mining District
— Keystone, South Dakota —
The Holy Terror Mine, located in Keystone, South Dakota (near Mt. Rushmore) was the deepest and oldest mine in the Keystone Mining District. It was developed from the surface down to the 1200 foot level. Historical records show that 62,000 ounces of gold were produced from 1896 to 1903. The mine briefly opened in 1938, and in 1942, the Holy Terror Mine was shut down by the War Measures Act. It has never reopened.
The Holy Terror Mine is rumored to be named after one of the original owners would refer to his wife as "Ain't she a holy terror" when she would find him in one of the local watering holes. His partner suggested that he name his new mine after her. He chose Holy Terror, instead of Jennie.

Also see . . . The Holy Terror Mine. By 1903, the Holy Terror Mine reached a depth of 1,200 feet. However, the mining company's early success was bogged down by underground water problems and litigation from fatal mine accidents and claim disputes. The mine ceased operation in 1903, and was allowed to fill with water. The Holy Terror had a brief revival from 1938 to 1942. Ore was mined in the neighboring Keystone Mine, brought to the surface through the Holy Terror shaft and processed at the Keystone mill. The story of the Holy Terror could see another revival in the future. A Canadian company in 2013 began drilling test holes to map the quality of the ore that remains (Submitted on August 14, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
