Garnet Creek

The Garnet 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 (Production): Production Notes = Production from 1900 to 1909 was reported to yield $7 to $9 per man-day and totaled $1,000 (Maddren, 1913).

Comment (Reference): Primary Reference = Reed, 1938

Comment (Workings): Workings / Exploration = Surface mining reported in 1937. Claims were staked in 1959.

Comment (Geology): Geologic Description = Garnet Creek is one of several tributaries to the Bettles River in which placer gold has been reported. The gold is in the present channel of the creek from the mouth to the forks, mostly on schist bedrock, but also in the lower few feet of the gravel (Reed, 1938). The gravel is coarse and waterworn, with many large boulders. The gravel is about 8 feet thick near the mouth of the creek and thins to 1 to 3 feet thick 1/2 mile from the mouth. Ground near the mouth of the creek was mined in 1937 and said to run $0.77 per square foot of bedrock (0.022 oz Au) (Reed, 1938). The gold was fairly fine, with a few nuggets. Reed (1938) reported the presence of a high channel, but it had not been prospected to any extent at that time. Reed (1938) described the bedrock in Garnet Creek as schist. Dillon (1996) mapped Ordovician black phyllite and marble near the mouth and Ordovician to Cambrian(?) quartz-feldspar and calcareous schists farther upstream.

Comment (Exploration): Status = Not determined

Comment (Deposit): Other Comments = Gold fineness reported to be 872.

Comment (Geology): Age = Quaternary.
