Comments on the geologic information

  • Geologic Description = This occurrence is a large color anomaly up to 1.5 miles wide which extends approximately 4 miles northeast from Home Creek towards Chignik Lagoon (Fields, 1977). The color is coincident with an area of pyritization and propylitization which may be related to a Tertiary dacite dike (Detterman and others, 1981) having a similar trend. The altered rocks are part of the Tolstoi Formation of Eocene and Paleocene age.? Several large quartz veins, up to 10 feet wide, were discovered by Bear Creek Mining Company during the period 1975-1976 (Fields, 1977). These were observed to carry galena and rare pyrite. A chip sample contained 120 ppm copper, 6270 ppm lead, 11.6 ppm molybdenum, 19.2 ppm silver, and 1600 ppm zinc. Massive quartz float containing sphalerite and disseminated pyrite was reported by Resource Associates of Alaska in 1979. It contained 490 ppm copper, 190 ppm lead, 5.5 ppm silver, and 4400 ppm zinc (Anderson and others, 1979).
  • Age = Tertiary.

Comments on the workings information

  • Workings / Exploration = This occurrence was briefly examined by Bear Creek Mining Company in 1975-1976. A vein chip sample contained 120 ppm copper, 6270 ppm lead, 11.6 ppm molybdenum, 19.2 ppm silver, and 1600 ppm zinc. Resource Associates of Alaska examined the area in 1979. They reported massive quartz float that contained 490 ppm copper, 190 ppm lead, 5.7 ppm silver, and 4400 ppm zinc.
