METALS 
 
 Beryllium.—Shipments of beryl concentrate declined considerably in
1967. The hand-cobbed concentrates were produced from the Scott mine in Custer
County operated by William Fitzner, and from various mines in Pennington
County, one of which was the Hugo, operated by L. W. J udson. Purchasers
of the beryl concentrates included Beryl Ores Co. of Arvada, Cob. 
 Ore from the Peerless mine of Northwest Beryllium Corp. in Pennington County
was treated at its flotation mill at Keystone. Beryl concentrate, one of
the six minerals recovered, was stockpiled. 
 
 Gold and Silver.—Except for 2 ounces of placer gold produced by Marvin
Kenoyer at his 3 W's mine in Custer County, all gold and silver came from
the Homestake mine in Lawrence County. This represented the largest single
source of revenue from mineral production in the State. According to the
annual report of Homestake Mining Co., gold and silver worth $21,200,375
were recovered from 1,896,311 tons of ore mined, compared with $21,309,115
worth of gold and silver recovered from 2,002,239 tons of ore in 1966. This
reduction of 105,928 tons of ore mined resulted in only a $108,740 loss of
recovered value. Ore from the Nineteen 
Ledge, below the 4,850-foot level, was substantially above average grade
and thus helped to raise the grade of ore milled to the highest level since
1959. The recovered value was $11.18 per ton, compared with $10.64 in 1966.
Improvements made by Homestake during the year included automation of the
number four winze ore hoist between the 6,800- and 4,850-foot levels, automation
of the two hydroelectric plants, and installation of a computer system. 
 
 Molybdenum.—Kerr-McGee Corp. reported a small shipment of molybdenum
recovered as a byproduct from uraniferous lignites previously mined in Harding
County. 
 
 Tin.—Tin concentrate (cassiterite) recovered from pegmatite ore processed
at Northwest Beryllium Corp.'s mill at Keystone was stockpiled. 
 
 Uranium.—Uranium output decreased substantially in 1967. No uraniferous
lignite was mined in Harding County. Production of uraniferous sandstone
ore was reported from eight operations in Fall River County. All of the uranium
ore produced in the State was processed at the Edgemont plant of Mines Development,
Inc., a subsidiary of The Susquehanna Corp. A small quantity of uranium ore
from three operations in Wyoming was also processed.
