Golden Horn

The Golden Horn is a gold, silver, and lead 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 = Surface and underground workings: By 1938 underground workings totaled 1,808 ft. and consisted of 303 ft. in two shafts, 1,025 ft. of drifts, and 480 ft. of crosscuts; all are now inaccessible. Beginning in 1977 the property was drilled and trenched. In the latter part of the 1980's it was stripped as an open cut.; Misco-Walsh Mining Company mined the residual placers and also continued exploration in 1994.

Comment (Reference): Primary Reference = Bundtzen and others, 1992

Comment (Reserve-Resource): Reserves = Inferred reserves of 148,000 tons at 0.29 oz/ton of Au and 0.64 oz/ton of Ag. Larger area of lower grade ore discussed in Bundtzen and others (1992) p. 28-29.

Comment (Geology): Geologic Description = Lode consists of irregularly distributed gold-scheelite-stibnite-galena-quartz veins at or near monzonite contact with sandstone and shale in vicinity of fault zone. Main lode reported to be 2-2.5 ft. wide. Ore is intergrown quartz and stibnite which carries gold.

Comment (Deposit): Model Name = Polymetallic veins

Comment (Deposit): Other Comments = Misco-Walsh Mining continued in 1994 to resolve metallurgical problems associated with the complex refractory ores.

Comment (Production): Production Notes = From 1925-1937 produced 2,706 oz. Au, 2,620 oz. Ag, and 9,336 lb. Pb.

Comment (Commodity): Ore Material = Auriferous arsenopyrite

Comment (Exploration): Status = Active
