Gardner and M. I. Ritchie, who assigned the patent to Utah Construction for
use. in the Shirley basin. The U.S. District Court of Cheyenne upheld the
$14 million merger of Utah Construction and Lucky Mc Uranium Corp., a suit
which was instituted by W. G. Knauff of Denver, Cob., in 1962. 
 Western Nuclear signed the fourth and largest contract for delivery of uranium
concentrates, which will bring the total backlog of sales to $64 million
through 1973. The new contracts with Combustion Engineering, Inc., called
for $26 million of uranium concentrate to be delivered in 
1971—73. 
 Contracts for uranium concentrate sales to the end of 1967 are shown in
table 12. Production from Western Nuclear's Golden Goose Shaft was begun
from five levels; most of the ore coming from sub-level development. The
third level of the shaft, connected to the Reserve shaft of Continental,
provided an extra escapeway for both shafts. Western Nuclear closed the D—3
underground workings because of hazards 
but planned on returning to the area later. Salvage operations at the Spook
mine were under lease to Malcolm Reeves prior to closing by Western Nuclear.
The company began heap leaching of the 300,000-cubicyard, low-grade stockpile
at the Day-Loma and Frazier-Lamac pits. The portable solvent-extraction unit
consisted of interconnected wooden laundry feeds, fiber-glass tanks, and
lines. The piles were crushed systematically to avoid channeling during leaching.
Western Nuclear entered into a joint exploration program with Sohio Petroleum
Co. on 10,000 acres in the Powder River basin. 
 
 Vanadium.—The quantity and value of vanadium recovered as a byproduct
of Wyoming uranium ores processed in the mill of Mines Development, Inc.,
at Edgemont, S. Dak., decreased considerably. The large decrease was due
mainly to the closing of the Hauber mine by Hometstake Mining Co.; also,
no production was reported from Converse County for 1967.
