The value of nonfuel minerals produced in Colorado in 1991 was about $338 million, a decrease of more than 12% from the value of production in 1990, according to data reported to the U.S. Bureau of Mines. The continued effects of an economic slowdown on metal values were evident for copper, gold, lead, molybdenum, silver, and zinc. Unit values for sand and gravel also fell in 1991.
