613The Mineral Industry 
of North Dakota 
This chapter has been prepared by the Bureau of Mines, U.S. Department of
the Interior, and the State Geological Survey of North Dakota under a cooperative
agreement for collecting information on all minerals except fuels. 
 
 
By Paul Mcllroy1 and William C. Henkes2 
 
 
Mineral production in North Dakota in 1967 was valued at $97.5 million, 5
percent less than in 1966. Most of the value came from mineral fuels—coal
(lignite), natural gas, natural gas liquids, peat, and crude petroleum. The
production value of 
uranium decreased sharply while stone and sulfur values increased significantly.
