Hannum Creek

The Hannum 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 (Exploration): Status = Inactive

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

Comment (Workings): Workings / Exploration = Over 4 miles of surface, open-cut placer workings are present along the channel of Hannum Creek, extending from the mouth of Collins Creek (a south tributary) upstream to the confluence with Cunningham Creek.

Comment (Geology): Geologic Description = Gold was discovered on Hannum Creek in 1900 (Moffit, 1905) and placer mining has occurred for over 4 miles of the channel, from the mouth of Collins Creek upstream to the confluence with Cunningham Creek. Gold is irregularly distributed on schist bedrock that is locally decomposed to blue clay. Gravels in the creek are 2-6 ft thick and the paystreak was 6 inches to 4 feet thick, with widths up to 100 feet. Galena (with hematite and pyrite) was recognized in early in placer concentrate (Moffit, 1905) and cassiterite was reported in 1947 (Anderson, 1947). Galena- and sphalerite-bearing lode deposits are present in headwaters to Hannum Creek (BN056) and Cunningham Creel (Harrys Creek, BN055). Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). Quaternary/Teritiary basalt flows locally cap ridges along the Hannum Creek valley.
