claims in the Shirley basin. The company also had a 5-percent royalty on
2,500 acres of claims owned by Kerr-McGee. Consolidated announced the discovery
of a low-grade uranium deposit at 12- to 185foot depths in the Poison Spider
area. However, exploration drilling on 17 of 6,500 acres owned by the company
had not delineated the ore body. 
 Petrotomics Co. awarded a $1.5 million contract to Stearns-Roger Corp. of
Denver, Col~o., to double the size of its uranium processing mill in the
Shirley basin area by late 1967. The company received two 100-ton, 900-horsepower,
diesel-electric, wheel-drive trucks, the first of six under a $1 million
order to Unit-Rig Co. of Tulsa, Okla. Also ordered, for delivery in December,
was a 1 7-cubic-yard shovel to be used for loading the new truck fleet. Tidewater
Oil Co. core drilled more than 1.5 million feet to locate and evaluate uranium
reserves in the Shirley basin. Kerr-McGee has obtained over 6,000 acres of
uranium reserves in the Gas Hills area over the last 2 years. 
 The Japanese Government authorized Mitsubishi Metal Mining Co. to expend
$200,000 to prospect a joint 14,000-acre plot with Rio Algom Corp. in the
Shirley basin. If an ore body of 0.2 percent U3O8 were found in sufficient
quantity, Mitsubishi and Rio Algoen were to construct a 1,000-ton-per-day
mill to process the ore. 
 Mining and Metals Division, Union Carbide Corp., contracted with S. S. Mullens

of Seattle, Wash., to strip, on a double-shift basis, 6 million cubic yards
of waste from a large pit immediately adjacent to and west of Federal American
Partners Loco C and D pits; the stripping was to be completed by December
1967. Some small ore bodies, encountered during stripping. were mined by
Union Carbide; Union Carbide was to mine the main ore body. 
 Utah Construction & Mining Co. concluded two more contracts for uranium
concentrates totaling more than 1.95 million pounds. One contract, with Sacramento
Municipal Utility District, called for shipments ranging from 950,000 pounds
minimum to 1.1 million pounds maximum during 1971. The second contract, with
General Electric Co. (GE), was for delivery of 1 million pounds during 1972.
This was the third contract with GE and brought the total purchased by GE
to 8 million pounds for delivery between October 1968 and December 1975;
the contract, signed in March, called for 1 million pounds per year from
1971 to 1975. With the new contracts, Utah Construction's backlog for sales
of uranium concentrate totaled nearly 13 million pounds, of which 23 percent
was committed to AEC agreements until 1970; the remainder was to industrial
users. The first shipment of uranium concentrate to Nordostschweizersche
Kraftwerke AG, Baden, Sweden, was made in the latter part of March. U.S.
Patent 3,3O~,140 "Leaching of Uranium Ore In-Situ" was granted to John
