Comments on the geologic information

  • chalcopyrite copied from delted record 10008504 (MRDS D000710)
  • Bull. 50 describes mineralogy: "Yellow uranium minerals including kasolite occur along fractures and are disseminated through weathered granite within 4 to 6 ft. of the graphite bed. The quartzite is less mineralized. Below the weathered zone, the bluish-gray unweathered granite contains disseminated uraninite, moybdenite, and pyrite. Other minerals identififed are uranophane, chalcopyrite, and galena."
  • lower adit was driven at an early date to explore a graphite zone. Uranophane was reported in the oxide zone by the applicant (but not observed by the USBM examiners). Pitchblende was found in upper adit. (DMEA-3587, p. 50 of 91)

General comments

Subject category Comment text
Deposit Record in the AEC RME-3125 is very sketchy. It simply lists minerals identified on the property as uraninite, uranophane, pyrite, molybdenite, and "graphite in schistose rock".
Deposit Seems odd to have both molybdenum and graphite in the same rock. Is this a case of not being able to differentiate the two similar-looking minerals or do both actually exist in the rock. If only one, which one? [A.B. Wilson, 24 June, 2010]
