OPEN-FILE REPORT 00-025 Alaska Resource Data File CA001 Site name(s): Alameda Creek Site type: Prospect ARDFno.: CA001 Latitude: 65.03 Quadrangle: CA A-5 Longitude: 161.05 Location description and accuracy: Placer ground located east of headwaters of Alameda Creek. The map site is in section 23.T.5S..R. 12 W., of the Kateel River Meridian. Cobb, 1972 (MF-386), location 46. Commodities: Main: Au Other: Ore minerals: Gold Gangue minerals: Magnetite Geologic description: This gold placer prospect occurs in a short section of Alameda Creek. The deposit ap­ parently is in a paleochannel uncut by the present stream. The deposit was explored by shafts, from which a small amount of gold was recovered. Pan concentrates contained a little gold, much magnetite and some undecomposed sulfides. Gravel on bedrock con­ tained about $0.01 per pan (gold at $20.67/ounce) (Smith and Eakin, 1911). Alteration: Age of mineralization: Quaternary. Deposit model: Placer Au-PGE (Cox and Singer, 1986; model 39a). Deposit model number (After Cox and Singer, 1986 or Bliss, 1992): 39a Production Status: None Site Status: Inactive Page 2 Alaska Resource Data File CA001 Workings/exploration: In the early 1900's one shaft was sunk 192 feet without reaching bedrock (Smith and Eakin, 1911). It was mainly in well-rounded quartz gravel. Another shaft hit lava at 32 feet. Gravel on bedrock contained about $0.01 per pan (gold at $20.67/ounce). Production notes: Gold was too scarce to support mining operations in 1909. Reserves: Additional comments: Stream gradient approximately 50 feet per mile.

It is in section 20, T. 3 S., R. 12 W., of the Kateel River Meridian. At various times, this site has been referred to as Haycock, Dime Creek Dredging Company, Dime Creek Mining Company, Haycock Mining Company, Moon and Ryan, and Smith. Cobb, 1972 (MF-389), location 45. Commodities: Main: Au Other: Cr, Pt Ore minerals: Chromite, gold, platinum Gangue minerals: Geologic description: Dime Creek flows near a fault (?) contact between Paleozoic metalimestones and Juras­ sic-Cretaceous andesites. The andesites are intruded by small, mafic and ultramafic plu- tons. At the old placer mine, the gold is mainly on metamorphosed, andesite bedrock; some gold also is in the overlying 2 to 3 feet of gravel. In the stream bed the paystreak is well defined, while on the benches there are several, linear concentrations of gold. These bench concentrations were thought to be caused by wave action. Assays of gold from Dime Creek returned as high as 961 parts gold and 32 parts silver. The placers also con­ tained platinum in approximate ratio to gold of 1:200. Analysis of platinum minerals from concentrate gave the following results: 88.8% Pt, 14.7% Ir, 4.3% Os + Ir, 1.1% Rh, 1.1 % Pd (Mertie, 1969). The placer deposits in the upper portion of the creek produced almost twice as much platinum as the lower claims. On both creek and bench claims the overburden thickness ranges from 10 to 30 feet; all of the ground was frozen. Heavy minerals in the concentrate from a second tier bench claim include iron-oxides, abundant chrome spinel, olivine, pyroxene, rare garnet, and rutile (Harrington, 1919). Alteration: Page 4 Alaska Resource Data File CA002 Age of mineralization: Quaternary. Deposit model: Placer Au-PGE (Cox and Singer, 1986; model 39a). Deposit model number (After Cox and Singer, 1986 or Bliss, 1992): 39a Production Status: Yes; small Site Status: Inactive Workings/exploration: The Dime Creek placers were mined intermittently from 1915 through at least the early 1990's. The deposits were worked mostly by drift and open-cut mining. A small dredge operated from 1931 to 1940. Production notes: On the lower end of Dime Creek, one ounce of platinum was produced for every 250 ounces of gold. On the upper claims there may have been as much as one ounce of plati­ num produced for every per 100 ounces of gold. A total of 35 ounces of platinum was recovered from placers at Dime Creek in 1917 (Harrington, 1919). Most of the 56 ounces of platinum reported from the Seward Peninsula in 1918 came from Dime Creek (Cathcart, 1920). Brooks and Martin (1921) report 32 ounces of platinum from the Dime Creek area. Reserves: Additional comments: Stream gradient is approximately 50 feet per mile.

Coordinates are for the approximate center of the workings. The site is in section 20, T. 3 S., R. 12 W., of the Kateel River Meridian. The site is also referred to as Little Eldorado Creek. Cobb, 1972 (MF-389), location 45. Commodities: Main: Au Other: Ore minerals: Gold Gangue minerals: Geologic description: Placer claims were staked in 1915 after gold was discovered near the mouth of [Little] Eldorado Creek. The creek follows the probable faulted contact between Paleozoic slate and limestone and Mesozoic andesitic volcanics. (Also see Dime Creek, ARDF number CA002). Alteration: Age of mineralization: Quaternary. Deposit model: Placer Au-PGE (Cox and Singer, 1986; model 39a). Deposit model number (After Cox and Singer, 1986 or Bliss, 1992): 39a Production Status: Yes; small Page? Alaska Resource Data File CA003 Site Status: Inactive Workings/exploration: Mines in the area were drift or open cuts. Most mining occurred between 1915 and 1919. Production notes: In 1915, the production from 3 claims was said to be $3,000 (gold at $20.67/ounce). In 1916 the total production from Eldorado and Dime Creeks totaled about $100,000 from 8 claims; total production from 16 claims in 1917 was $150,000 (Harrington, 1919). Reserves: Additional comments: Although placer gold was first discovered on Little Eldorado Creek, the richest placer ground was on Dime Creek. Stream gradient approximately 50 feet per mile.

Cobb Open-File Report 82-785 1982 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards. REFERENCE LIST The following references give data, as of May 1, 1982, on localities where tungsten minerals have been found in Alaska. References are keyed by number to locations shown on the accompanying map. An asterisk (*) preceding a locality name indicates recorded production. Localities 93-161 (in the Tanacross quadrangle) and 183-197 (in the Chignik and Sutwik Island quadrangles) are the sites of samples collected during geochemical investigations that were part of the Alaska Mineral Resource Assessment Program (AMRAP). Tungsten minerals were identified during microscopic study of the nonmagnetic fractions of the heavy-mineral concentrates of samples from these localities. In most instances the report(s) cited for each occurrence is a summary of data in older reports and was compiled since 1975. Most of the summary reports contain lists of the reports used in their compilation. Citations are in standard bibliographic format with the exception that each includes, in parentheses, an abbreviation for the report or map series and the number of the report or map.

These three refuges are administered collectively as the Koyukuk/Nowitna Refuge Complex. Narrative items common to all three units are discussed in the Koyukuk and Northern Unit of Innoko report. Any additional events are reported in respective sections. The Koyukuk National Wildlife Refuge (NWR) is located in west central Alaska, about 270 air miles west of Fairbanks and 330 air miles northwest of Anchorage. The exterior boundaries encompass 4.6 million acres. This refuge lies within the roughly circular floodplain basin of the Koyukuk River. The extensive forested floodplain is surrounded by hills 1500' - 4000' to the north, east, and west, and the Yukon River to the south. The Koyukuk NWR was established December 2, 1980 with passage of the Alaska National Interest Lands Conservation Act (ANILCA). The refuge was established and is managed for the following purposes: 1. To conserve fish and wildlife populations and habitats in their natural diversity including, but not limited to, waterfowl and other migratory birds, moose, caribou, furbearers and salmon; 2.
