215The Mineral Industry of Idaho This chapter has been prepared under a cooperative agreement between the Bureau of Mines, U.S. Department of the Interior, and the Idaho Bureau of Mines and Geology for collecting information on all minerals except fuels. By William C. Butterman' The value of Idaho's mineral production in 1972 was 106 million, ~% below its value in 1971. Silver was again the leading mineral commodity, accounting for 23% of the State's mineral revenues, in spite of a sharp drop in output due to a disastrous fire at the Sunshine mine. As in the past, the next most valuable commodities, were lead, zinc, sand and gravel and phosphate rock. The first three of these accounted for 40% of the total production value. The quantity of lead and zinc produced declined by 8% and 14%, respectively; however, owing to higher prices, the value of lead produced remained essentially the same as in 1971, and the value of zinc output dropped only 5%. Sand and gravel was down 32% in quantity and 10% in value. The combined value of nine other commodities listed individually in table 1 decreased 9% but the value of the remaining items increased 10% compared with values in 1971. Mining companies in the Coeur d'Alene district funded a year-long study by the University of Idaho on revegetation of ground areas covered by mine wastes. A variety of grasses, shrubs, and trees were tested. It was planned to follow the study with a large-scale demonstration project in Shoshone County, which would be a cooperative effort of the sponsoring mines and the University.2 The University began 1 Physical scientist, Division of Nonferrous Metals—Mineral Supply. 2 The Wallace Miner.
