Comments on the reserve resource information

  • DATA INSUFFICIENT TO ESTIMATE RESERVE
  • HIGHLY SPECULATIVE RESOURCE ESTIMATE BY R. B. HALL. LATERAL EXTENT OF BED UNKNOWN.
  • STUDY NEEDED. THE PURITY OF THE ALUNITE AND THE UNUSUAL FEATURES OF ITS OCCURRENCE MAKES ADDITIONAL SURFACE, SUBSURFACE, AND LABORATORY STUDIES DESIRABLE.

Comments on development

  • ALUNITE DISCOVERED IN CUTTINGS FROM SHALLOW HOLES DRILLED DURING EXPLORATION FOR OIL AND GAS. BULLDOZER TRENCH 25 FT DEEP MADE BY MOUNTAIN FUEL SUPPLY CO. IN 1958 (?) FOLLOWING DRILLHOLE DISCOVERY IN 1957 . TRENCH MEASURES 40 FT LONG, 10 FT WIDE, AND 30 FT DEEP.

General comments

Subject category Comment text
General "Alunite-bearing claystone is exposed near the base of a bulldozer trench that is 40 feet long, 10 feet wide, and 30 feet deep. Exposures here indicate that the alunite claystone is approximately 12 feet thick and dips about two degrees south. Flame photometer analysis of two samples indicates 32.0% and 29.5% Al2O3 and 6.8% and 5.8% K2O respeictively. A similar white claystone, 6 feet thick was penetrated at a depth of 145 feet by a core hole drilled a mile southwest of the alunite trench, but it is not known if this bed is alunite-bearing or not." (Bull 50, p. 5)
Deposit LOVE AND BLACKMON ( 1962 ) MENTION 8 FT OF WHITE CLAYSTONE CONTAINING 60 % TO 90 % ALUNITE
Deposit ORIGIN OF ALUNITE HERE IS ENIGMATIC ; 3 FIELD OBSERV
