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).
Location: The mine is at an elevation of about 1000 feet 1.5 miles southwest of Lamplugh Glacier. It is about 0.6 mile west-northwest of the LeRoy Mine (MF023) near the center of the NW 1/4, section 34, T. 34 S., R. 51 E., of the Copper River Meridian. Twenhofel and others (1949, p. 33) give the elevation of the same prospect as 850 feet.
Geology: 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).
Workings: 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.
Age: Late Cretaceous or younger.
Alteration: Gougy (clay-rich?) material reported along vein-fissures.
Production: 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.
Reserves: No reserves.

Commodities (Major) - Au; (Minor) - Ag, Pb
