Gold Creek

The Gold Creek 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 (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Deposit): Other Comments = Gold fineness reported to range between 900 and 931. Alaska Kardex Nos. 031-030, 031-104, 031-103, 031-102, 031-101, 031-100, 031-099, 031-098, 031-092, 031-091, 031-088, 031-066 (Kardex is a card file mining claim information system located at the State of Alaska DNR Public Information Center in Fairbanks).

Comment (Geology): Geologic Description = Placer gold has been mined in Gold Creek from the present stream channel in gravels reported to be 2 to 7 feet deep; from a deeply buried channel approximately 50 to 100 feet below the present channel; and from benches about 8 feet above the present channel. The gravel in the present channel is coarse and waterworn, with many boulders. The gravel from one place in the deep channel is fairly fine, with only a few boulders. The ancestral Gold Creek originally flowed to the Middle Fork through what is now lower Linda Creek, but glacial drainage derangement or stream capture diverted the lower mile to its present course. Reed (1938) described the bedrock of Gold Creek as schist cut by a diorite dike a short distance upstream from the mouth of Magnet Creek. Dillon and Reifenstuhl (1995) mapped the country rocks in most of the Gold Creek drainage as sedimentary units of the Beaucoup Formation; other rocks present are a sequence of Devonian carbonaceous, siliceous, and calcareous sedimentary and felsic volcanic rocks and one occurrence of Devonian metabasite, which may correspond to the diorite dike described by Reed. The richest placers were between constrictions in the valley caused by resistant schist and diorite. The richest claim was at the mouth of Magnet Creek, just downstream from the diorite dike. Values from various operations along the creek were reported by Reed (1938) to run from about $0.25 to $1.50 per square foot of bedrock. Most of the gold forms smooth, shot-like pieces and small nuggets, but some pieces from high on the creek are angular and may not have been transported far. Angular fragments of stibnite in quartz have been found in the gravels, and some pyritization has been noted in the schist bedrock.

Comment (Reference): Primary Reference = Reed, 1938

Comment (Workings): Workings / Exploration = Surface and underground drift mining in the early days. Later mining activity was undoubtedly mechanized, but there is no description of this activity.

Comment (Exploration): Status = Active

Comment (Production): Production Notes = Gold was discovered in Gold Creek during the summer of 1900, and it was one of the first creeks to be mined in the district (Reed, 1938). Since then it has been a significant producer. The creek was mined in most years until around 1916, and mining continued sporadically after that, probably to the present (1998). The stream course has been mined for about 8 miles. Values reported by Reed (1938) ranged from $0.25 to $1.50 per square foot of bedrock. Production through 1909 was estimated by Maddren (1913) to be approximately $232,000.

Comment (Geology): Age = Quaternary.
