Oregon Creek

The Oregon 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 (Geology): Geologic Description = Gold was discovered in Oregon Creek and adjacent bench deposits before 1901 (Brooks and others, 1901, p. 69, 92-94); the deposits were worked extensively before 1918. Gold, accompanied by magnetite, garnet, bismuth, rutile, and scheelite, occurs in the placer deposits (Collier and others, 1908, p. 211-213; Cobb, 1975 [MR-66]; Anderson, 1947). Boulders of schist containing galena and sphalerite were found in the placer open cuts (Herreid, 1970). Stibnite and quartz boulders occur upstream in Mountain Creek, and stibnite was found in place in schist on the south side of Oregon Creek by Kennecott Exploration Company in 1992. Calcareous schist and schistose marble boulders containing galena and sphalerite are similar to rocks found upstream at the Aurora (NM140) and Christophosen (NM141) prospects. The boulders are either derived from these deposits or another deposit closer to the placer deposits. Boulders of gneiss, apparently derived from the Kigluaik Mountains, are also found at Oregon Creek. The placer deposit in the active creek was covered by only a few feet of gravel. Bench deposits were covered by about 20 to 25 feet of gravel. These deposits were mined both by drift and surface hydraulic methods. The pay zone on Oregon Creek was about 70 feet wide but less than 1 foot thick. Bedrock in the Oregon Creek area is mainly calc-schist, but outcrops on the north side of the creek appear to be a felsic schist, similar to the felsic schist unit exposed at Aurora Creek (Bundtzen and others, 1994).

Comment (Workings): Workings / Exploration = The placer deposits have been worked by surface hand operations, hydraulic cuts, and drift mining. Placer mining began in 1900; the gold produced in 1900 from Oregon and nearby Nugget (NM147), Mountain (NM145) and Hungry Creeks (NM149) was estimated at about 2,400 ounces (Brooks and others, 1901, p. 69). Mining was reported by Moffit (1905), Collier and others (1908), in 1914 by Eakin (1915 [B 622-I, p. 369-370]), in 1916 (Mertie, 1918 [B 662-I, p. 455]), and in 1918 (Cathcart, 1920, p. 189). The area was worked by non-float mechanical methods in 1940 (Smith, 1942, p. 57). Some mining by open-cut methods on the patented claims occurred in the 1990's.

Comment (Reserve-Resource): Reserves = There is at least a small placer resource left in the area, especially in the bench deposits.

Comment (Production): Production Notes = Patented claims cover most of the bench placers.

Comment (Deposit): Model Name = Alluvial placer Au (Cox and Singer, 1986; model 39a).

Comment (Exploration): Status = Active

Comment (Geology): Age = Quaternary.
