Dutch Creek

The Dutch 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.

Alterations

Alteration Type: L
Alteration Text: Hydrothermally altered zones at the headwaters of Dutch Creek are noted by Reed and others (1978). Alteration mineralogy is not described at this site. However, based on its reported similarity to altered zones at Dollar and Thunder Creeks, it is most likely argillic alteration of Mesozoic sedimentary rocks.

Comments

Comment (Deposit): Other Comments = See also First Creek (TL039). Reed and others (1978) indicate that hydrothermally altered zones similar to those at the headwaters of Dutch Creek are observed along Dollar (TL031) and Thunder Creeks (TL032, TL058), at the headwaters of Treasure (TL030) and Bear Creeks (TL017) and at an unnamed locality east of McDoel Peak (TL053).

Comment (Reference): Primary Reference = Reed and others, 1978

Comment (Workings): Workings / Exploration = The drainage has been prospected and mined by various small scale surface methods. Reed and others (1978) report that in 1974 production justified an industry exploration drilling program.

Comment (Geology): Geologic Description = Bedrock at Dutch Creek is mapped as Mesozoic marine sedimentary strata (KJs) by Reed and Nelson (1980). The drainage is controlled by a northeast trending, high angle normal fault, known as the Dutch Creek Lineament (Hawley and Clark, 1973), that is parallel to a similar structure in the Cache Creek a mile and one half to the southeast. Hydrothermally altered zones at the headwaters of Dutch Creek are noted by Reed and others (1978). Gold fineness ranges from 875.75 to 877.75 and averages 876 (Clark and Hawley, 1968).? C.C. Hawley and Associates, Inc. (1978) report that the total production from the Dutch Creek placers is not known, but was probably small. Potentially productive ground is represented by placer claims in the Dutch Creek area which extend approximately four miles upstream from the coordinates given in this record and includes Basic, Siwash, Blank and Prospect Creeks, tributaries to Dutch Creek. ? Hydrothermally altered zones similar to those at the headwaters of Dutch Creek are observed along Dollar (TL031) and Thunder Creeks (TL032, TL058), at the headwaters of Treasure (TL030) and Bear Creeks (TL017) and at an unnamed locality east of McDoel Peak (TL053) (Reed and others, 1978). ? Also see First Creek (TL039).

Comment (Geology): Age = Pleistocene.

Comment (Production): Production Notes = C.C. Hawley and Associates, Inc. (1978) indicate that the total production is not known, but was probably small. Placer claims extend to the following tributaries and to Dutch Creek: Basic Creek, Siwash Creek, Blank Creek and Prospect Creek, approximately four miles upstream from the coordinates given in this record.

Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).
