  477The Mineral Industry of 
South Dakota 
This chapter has been prepared under a Memorandum of Understanding between
the 
Bureau of Mines, U.S. Department of the Interior, and the South Dakota Geological
Survey for collecting information on all nonfuel minerals. 
By James H. Aase,1 Wanda J. West,2 and Fred V. Steece3 
The value of nonfuel mineral production in South Dakota for 1978 and 1979
was $114.8 million and $148.7 million, respectively, setting records each
year. 
The State's nonfuel mineral output was derived from three metallic and nine
nonmetallic mineral commodities. Gold continued as the leading commodity
in terms of value during the biennium 1978-79, accounting for approximately
half of the State 
total. Other principal mineral commodities produced, in descending order
of value, included cement, stone, and sand and gravel. 
 Nationally, South Dakota ranked 38th among the States in value of nonfuel
mineral production in 1978. The State led the Nation in gold production in
1978 and was second, following Utah, in 1979. 
 Although the quantity of gold produced in
