The value of nonfuel mineral production in 1991 was $90.8 million, a $27 million decline from that of 1990. The decrease was largely attributable to a drop in output of crushed stone and construction sand and gravel, the State's leading mineral commodities. The 1991 value was the lowest since 1986 when the value totaled $80.5 million. Other mineral commodities produced included clays, feldspar, mica, industrial sand, and dimension stone.
