REVIEW BY MINERAL COMMODITIES 
 
MINERAL FUELS 
 
 Accounting for 78 percent of the value of total mineral production in the
State, output of mineral fuels in 1967 increased 2 percent, from $405.0 million
to $412.7 million. Petroleum, the single most valuable commodity, accounted
for 66 percent, or $35 1.7 million, of the total. Marketed natural gas, the
third most valuable commod'ity, constituted 7 percent, or $35 million, of
the total value. 
 
 Coal (Bituminous).—Output of coal from 14 mines in 7 counties decreased
2 percent in quantity, while value increased $36,000. Increased production
by Wyodak Resources Development Corp. in Campbell County, Kemmerer Coal Co.
(Elkol strip) in Lincoln County, Big Horn Coal Co. and Welch ' Cbal Co. in
Sheridan County, and Dusky Diamond Coal Co. and T—K Coal Co. in Hot
Springs County was offset by decreased production of Monolith Portland Midwest
Co. and Rosebud Coal Sales Co. in Carbon County, Best Coal Co. and PP&L
(Dave Johnston strip) in Converse County, Kemmerer Coal Co. (Sorensen strip)
in Lincoln ' County, Roncco Coal Co. in Hot Springs County, and Edwin L.
Swanson Brothers and Gunn-Quealy Coal Co. in Sweetwater County. 
 Black Hills Power & Light Co. announced plans for a $5 million, 20-megawatt,
coal-fueled, air-cooled condenser, electric-generating plant at Wyodak; a
smaller, custom-built experimental unit has 
been in use for 6 years. Air-cooled condensers, developed in Europe, allow
units to ' be constructed in areas where water supply is limited. Scheduled
for operation by fall of 1969, the plant will be the first of its kind in
' the United States; construction was to begin in early 1968. Success of
the plant could result in construction of a 150-megawatt generating plant.
