Geographic coordinates

Geographic coordinates: -151.0828, 62.55954 (WGS84)
Relative position C.C. Hawley and Associates, Inc. (1978, Figure 4.2-B(3)) show placer ground on Dutch Creek between Basic Creek on the south and Prospect Creek on the north in Sections 25, 35, and 36, T. 29 N., R. 10 W., of the Seward Meridian. Claims also cover northwest flowing tributaries to Dutch Creek along this section (Reed and others, 1978, locality 87).

Alteration

  • (Local) 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 on the geologic information

  • 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).

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Mining district

District name Yentna

Comments on the production information

  • 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.

Comments on the workings information

  • 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.
