713The Mineral Industry of 
South Dakota 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, U.S. Department of the Interior, and the South Dakota State
Geological Survey for collecting information on all minerals except fuels.

 
 
By Franklin H. Persse' and William C. Henkes 2 
 
 
 Mineral production in South Dakota during 1967 was valued at $52.6 million,
essentially the same as in 1966. The record high for the State was $54.1
million in 1963. 
 The value of metals produced declined 5 percent, whereas the value of nonmetals
increased 2 percent. However, this decline in the value of metals produced
did not 
prevent South Dakota from leading the Nation in gold output for the 19th
consecutive year. All but 2 ounces of the total State output was produced
at the Homestake mine at Lead.
