Mineral produced in Illinois during 1971 were valued at $729.7 million. This amount was $13.4 million, or 1.9%, higher than the record production of $716.3 million established in 1970. The record production of 1971 was the sixth successive all-time high in total annual mineral value in the state. During 1971 stone, common sand, gravel, tripoli, and fluorspar had gains in value from their respective total values for 1970. Other mineral products showing gains from their 1970 values were Portland cement, masonry cement, lime, and clay products. The total value of coal, the state's most important single mineral value, showed a slight loss from its 1970 value. Other Illinois mineral products also showing losses in 1971 from the 1970 values include crude oil, silica sand, zinc, and lead. The quantity and the value of minerals produced in Illinois in 1971, and in other years, are summarized in the tables and maps of this report.
