Home Creek

The Home Creek is a lead, zinc, and silver mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Reference): Primary Reference = Fields, 1977

Comment (Geology): Age = Tertiary.

Comment (Exploration): Status = Inactive

Comment (Workings): 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.

Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c)

Comment (Deposit): Other Comments = A part of this site is on land conveyed to or patented by the Bristol Bay Native Corporation. The remainder is within Alaska Peninsula National Wildlife Refuge.

Comment (Geology): 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).
