Comments on the ownership information

  • Comment from Dave Pit (0560070150=10181680): PETROMICS INC (TIDEWATER OIL) [ABWilson notes the probable misspelling of Petrotomics] The only reference was "WYO.G.S.FOR MAS"

Comments on the production information

  • LAST HALF OF 1978 MILL OPERATED AT 1,300 TONS / DAY. 1979 MILL OPERATED AT 1,500 TONS / DAY.

Comments on the workings information

  • CONVENTIONAL MINING TECHNIQUES EMPLOYED. NOMINAL CAPACITY - 1,500 TONS / DAY. URANIUM GOES TO UTILITIES IN WISCONSIN, NEW ENGLAND AND ALABAMA.

Comments on development

  • 1962 PLACED A 500 TON / DAY MILL INTO OPERATION. 1969 WENT TO 1 500 TONS / DAY. SHUT DOWN 1973 - 74 DUE TO UNFAVORABLE URANIUM MARKET.
  • In July 1960 the Ptrotomics Co. began to strip 3 million yards of overburden in preparation for mining large high-grde uranium ore boides on their property in secs. 4 and 9, T27N, R78W. The first ore was mined form this property in December 1960. [...] In October 1966, Petrotomics Co. started a new open pit in Sec. 15, T27N, R78W. The first ore from this pit was mined in Septermber 1967 from high-grade ore bodies about 180 below the ground surface. (Harshman, 1972, p. 6-7)

General comments

Subject category Comment text
Deposit BELIEVED TO BE ON THE UP- DIP SIDE OF THE SAME SANDSTONE MINED BY THE UTAH C AND M COMPANY.
General deleted record 0560070187 was "REVISED BY MILS 9-79". That was the only reference given.
General Combined records for Dave Pit, Dave Section 10 Pit and Dave and T G S into this record and deleted them as duplicates. This is all part of the same deposit.
