A.F. Parker

The A.F. Parker is a gold 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 (Workings): Workings / Exploration = Veins were discovered and claims located in 1938. Some ore was produced from surface cuts or in a 16-foot drift-adit before July 1940. The ore was transported to the beach by an aerial tram.

Comment (Exploration): Status = Inactive

Comment (Deposit): Other Comments = Apparently there was no production after about 1940. Mine is in Glacier Bay National Park and Preserve in the Reid Inlet gold area defined by Kimball and others (1978).

Comment (Deposit): Model Name = Low-sulfide gold-quartz vein (Cox and Singer, 1986; model 36a).

Comment (Production): Production Notes = Seven or eight tons of ore was shipped before July 1940, and additional sacked ore was seen by Twenhofel and others (1949, p. 33) when they visited the property in 1940.

Comment (Reference): Primary Reference = Kimball and others, 1978; Twenhofel and others, 1949

Comment (Reserve-Resource): Reserves = No reserves.

Comment (Commodity): Ore Material = Gold (native)

Comment (Commodity): Gangue = altered rock material

Comment (Geology): Geologic Description = Golf-bearing veins at the A. F. Parker prospect cut granitic host rocks. The veins are discontinuous gold-rich structures which occur in gougy vein-faults of diverse strikes. Locally, the gold-bearing veins are cut off by low-angle post-mineral faults. Short vein segments also occur near a 16-foot adit driven along a gougy vein that strikes east-northeast. Samples of gougy vein material contained only a trace of gold, but quartz vein material containing more than 2 ounces per ton gold was found on the dump, and a thin quartz vein in the face of the adit contained 5.13 ounce per ton gold (grab sample). A thin vein in an outcrop about 35 feet above the short adit contained 2.46 ounces per ton gold over 0.1 foot (Kimball and others, 1978, p. C234-236). Galena, pyrite, and free gold were reported by MacKevett and others (1971, p. 64).

Comment (Geology): Age = Late Cretaceous or younger.
