571The Mineral Industry of Wisconsin This chapter has been prepared by the Bureau of Mines, U.S. Department of the Interior, and the Geological and Natural History Survey of Wisconsin, under a Memorandum of Understanding for collecting information on all nonfuel minerals in the State. By James J. Hi1P and Thomas J. Evans2 The value of nonfuel mineral production in Wisconsin was $159.2 million in 1978 and $179.7 million in 1979. The increase in value primarily reflects inflationary pressures that have caused the unit values of most mineral commodities to escalate along with other products in the State's economy. Nonmetallic minerals, especially sand and gravel and crushed stone used for construction, continued to dominate the mineral scene in quantity and value. In the 1978-79 biennium, iron ore was the leading metallic mineral commodity produced in Wisconsin. Witl~ the closing of Eagle-Picher Industries' zinc mine in October 1979, iron ore became the sole metallic mineral produced in the State. Although three massive sulfide deposits have been discovered in the State since 1968, only one is currently being evaluated for production purposes.
