The CGS Mineral Resources Section estimates the total value of 1996 mineral fuel production in Colorado to be $1,759 million dollars. The value of Colorado coal production is estimated at $321 million.
Nonfuel mineral production — including metals, industrial minerals, and construction materials – The USGS Mineral Information Office estimates the value of the 1996 Colorado mineral production at $528 million, down 7 percent from the 1995 value of $570 million. The decrease in value is due to lower molybdenum production and prices, and the temporary closure of the Black Cloud Mine in Leadville. Sand and gravel, aggregate, construction clay, and gypsum all increased production in 1996.
