natural gas ($2.2 million), molybdenum ($4.1 million), stone ($5.8 million),
vanadium ($1.6 million), and zinc ($1.4 million); whereas, only petroleum
had a substantial 
 
increase ($1.5 million). Petroleum contributed 29 percent of the total value
of production in the State, and molybdenum, 24 percent. The production of
metals comprised 44 percent of the State's total value of mineral production,
fuels 42 percent, and nonmetals 14 percent.
