MINERAL INVESTIGATIONS IN THE ANIAK MINING 

DISTRICT, SOUTHWESTERN ALASKA - 2003 FIELD 

SEASON 

ABSTRACT 

The Aniak Mining District study area encompasses approximately 27 million acres (11 

million hectares) in southwestern Alaska and includes part of the adjacent Anvik, 

Iditarod, Innoko, Marshall, and McGrath mining districts. The district contains over 400 

mineral deposits and prospects, including those located in the historic mining areas of 

Iditarod-Flat, Nyac, Crooked Creek-Donlin Creek, Candle Creek, Ganes Creek, Nixon 

Fork, Illinois Creek, and Red Devil. Due to the size of the study area, the district was 

divided into three parts: the northeastern, central, and southwestern. 

In 2003, the Bureau of Land Management (BLM) began a multi-year mineral resource 

assessment of the Aniak Mining District by examining the northeastern part of the 

district. BLM geologists located, mapped, and/or sampled 100 of the 208 documented 

sites in this part of the study area. During the field season 351 rock, pan concentrate, 

stream sediment, soil, and placer samples were collected and analyzed. 

Sites containing elevated metal values include: gold, silver, copper, and zinc at Badnews; 

silver, copper, and zinc at Bowser; nickel and copper at Chip Loy; gold, silver, and zinc 

at Crash North; gold, silver, copper, and zinc at Dall; placer gold at Fourth of July Creek; 

gold at Independence Mine area; gold and lead at Kaatz Prospect; gold at Little Creek; 

placer gold at Mackie Creek; placer gold at Moore Creek; gold and copper at Nixon Fork 

(Mespelt Mill) tailings; platinum and palladium at Roberts PGM; gold at Telephone Hill 

(Tele) Prospect; gold and silver at Terra/Fish Creek area; and gold, silver, copper, and tin 

at Win.

INTRODUCTION 

In 2003, the Bureau of Land Management (BLM) Division of Energy and Solid Minerals 

started a 4-year mineral resource assessment of the Aniak Mining District. Mineral 

assessment objectives are to identify the nature, extent, and development potential of 

mineral resources; perform mining feasibility studies through hypothetical mine models 

on mineral deposits that have economic potential; and fund geophysical investigations of 

areas having the potential to contain concealed mineral deposits. BLM work includes 

locating, sampling, mapping geology and mine workings, and evaluating historic mines, 

prospects, and mineral occurrences. The BLM also investigates, in more detail, newly 

discovered prospects and deposits. The Aniak Mining District is part of BLM’s mining 

district evaluation program authorized under Section 1010 of the Alaska National Interest 

Lands Conservation Act (ANILCA), which has been continued since the early 1980’s. 

The Aniak Mining District study area encompasses approximately 27 million acres 

(42,000 square miles (11 million hectares)) in southwestern Alaska and includes parts of 

the adjacent Anvik, Iditarod, Innoko, Marshall, and McGrath mining districts (fig. 1). 

The area contains over 400 mineral sites, including those located in the historic mining 

areas of Iditarod-Flat, Nyac, Crooked Creek-Donlin Creek, Candle Creek, Ganes Creek, 

Nixon Fork, Illinois Creek, and Red Devil. Due to the size of the Aniak Mining District 

study area, the district was divided into three parts: the northeastern, central, and 

southwestern. 

Placer gold has been the main commodity produced from the area since the late 1800’s. 

Placer platinum and mercury as well as lode gold and mercury, with byproduct silver and 

antimony, have also been mined. Other commodities prospected for in the region include 

barite, copper, lead, molybdenum, tin, tungsten, uranium, and zinc. 1

This report contains analytical data of samples collected during the 2003 field season. 

Similar reports will be published after the 2004 and 2005 field seasons. A more detailed 

final report with the BLM’s mineral assessment of the district, all analytical data, and 

property summaries will be published in 2006. An economic analysis report and an 

industrial minerals report will also be published in 2006.

2003 FIELD SEASON REVIEW

Fieldwork during 2003 consisted of a 46 day field season during June and July, focusing 

on property examinations and sample collection in the northeastern part of the district 

(figure 1). A literature search identified 208 properties in this part of the district. Figure 

2 shows the locations and densities of the mineral properties in the northeastern part of 

the district and identifies the properties discussed in this report. Sites for which we had 

more geochemical and geological data, and more precise locations, were given priority 

because of the volume of sites and time constraints. During the field season BLM 

geologists were able to look for 115 sites, locate 100 of those sites, and collect 351 rock, 

pan concentrate, stream sediment, soil, and placer samples in the process (Plate 1). 

McGrath was used as the base for the first half of the field season and Farewell Lake was 

used for the second half. Areas investigated from McGrath included the Ganes Creek 

and Moore Creek areas to the west, Cloudy Mountain to the north, Nixon Fork to the 

east, and Vinasale Mountain to the south. From Farewell Lake, the Post, Windy Fork, 

and Middle Fork rivers draining the Alaska Range and the areas including the Lone and 

White mountains were investigated. 

Sites containing elevated metal values include the Badnews, Bowser, Chip Loy, Crash 

North, Dall, Fourth of July Creek, Independence Mine area, Kaatz Prospect, Little Creek, 

Mackie Creek, Moore Creek, Nixon Fork (Mespelt Mill) tailings, Roberts PGM, 

Telephone Hill (Tele) Prospect, Terra-Fish Creek area, and Win properties. Following 

are brief discussions on each of these properties: 

Badnews - Three distinct skarn zones that replace light gray, fine-grained limestone, 

trending north-northeast to east-northeast extend for several hundred feet were noted at 

this site. Zones consist of dark, rusty, pitch limonite weathered surface with local thin 

crusts of whitish zinc and copper oxides. Samples collected from the three zones 

contained variable concentrations of pyrrhotite, sphalerite, pyrite, and trace galena. 

Massive sulfide veins range from 1 to 5 ft wide (0.3 to 1 m). Samples collected from a 

5.5 by 10 ft (1.7 by 3 m) exposure included a select sample (13323, map no. 99) that 

contained 0.584 ppm gold and 10.3 percent zinc and a 5.5 ft (1.7 m) continuous chip 

sample (13324, map no. 99) that contained 0.333 ppm gold and 7.31 percent zinc. Two 

representative chip samples collected from a 9.8-ft-wide (3.0 m) zone included sample 

(13246, map no. 99) which contained 0.86 oz/ton (29 g/t) gold, 0.81 oz/ton (28 g/t) silver, 

and 6.21 percent zinc and sample (13245, map no. 99) which contained 0.462 ppm gold 

and 5.3 percent zinc. A select sample from the third zone contained 3.47 oz/ton (119 g/t) 

silver, 3.79 percent copper, and 19.7 percent zinc (13362, map no. 99). 

Bowser - Massive sulfide veins were sampled in the Bowser Creek Main area. Select 

sample (13267, map no. 126), from a stockpile of ore, contained 36.1 oz/ton (1,240 g/t) 

silver, 13.95 percent lead, and 16.2 percent zinc. A 2.3 ft (0.70 m) continuous chip 

sample (13268, map no. 126) of galena and sphalerite from a trench, blasted out of 

silicified limestone, contained 23.9 oz/ton (819 g/t) silver, 7.41 percent lead, and 11.1 

percent zinc. In addition to lead and zinc mineralization in the Bowser Creek Northeast 
4

area, continuous chip sample 13361 (map no. 124) contained 0.0318 oz/ton (1.09 g/t) 

gold and 1 percent copper. Float sample 13269 (map no. 122), collected from a shallow 

trench on the northeast edge of the quartz monzonite knob near the headwaters of Bowser 

Creek, contained 3.06 oz/ton (105 g/t) silver and 21.2 percent zinc. 

Chip Loy - Discontinuous pods of massive chalcopyrite, pyrite, and pyrrhotite within a 

northeast trending shear zone, 40 to 150 ft wide (10 to 46 m), were cutting diabase and 

hornfels. The north end of the shear zone is cutoff by a cliff face while the south end is 

buried under tundra. Three of four samples collected along the mineralized zone 

contained elevated nickel values. At the northern end, representative chip sample 13335 

(map no. 92) contained 1.34 percent nickel, 5,700 ppm copper, and 0.021 ppm gold. In 

the central area, select sample 13337 (map no. 92) contained 1.21 percent nickel, 9,760 

ppm copper, and 0.019 ppm gold. At the southern end, sample 13338 (map no. 92) 

contained 2.26 percent nickel and 7,150 ppm copper. 

Crash North - On the southern slope of the east trending ridge immediately north of the 

Crash property, sulfides contained anomalous amounts of silver, base metals, and gold. 

The sulfide minerals were found within vuggy quartz veins, thin veins following 

fractures, and in bedded silty carbonates. A spaced chip sample (13095, map no. 113) of 

quartz vein within a silty limestone contained 9.5 percent zinc. Near the top of the ridge 

a north-northeast trending breccia zone, 33 ft wide (10 m) by 164 ft (50.0 m), was 

truncated by low angle faults on the north side and cut by a sharp, steeply dipping fault 

on the west side. A 7 in (0.2 m) channel sample (13263, map no. 113) from this breccia 

ran as high as 0.834 ppm gold. Sulfide mineralization diffuses to the east, where sample 

13321 (map no. 113) collected from 3- to 4-in-thick (0.1 m) beds of malachite stained 

carbonate, contained 235 ppm silver and 6,080 ppm copper. 

Dall - A 10-ft-wide (3 m) zone of massive sulfide bodies interbedded with gossanous 

material and siliceous hornfels, was exposed for nearly 200 ft (60 m) along strike. Two 

continuous chip samples (13327-28, map no. 101) taken 60 ft (20 m) apart along the zone 

averaged 7.6 oz/ton (260 g/t) silver, 1.87 percent copper, and 1.89 percent zinc. Two 

select samples (13329-30, map no. 101) of the massive sulfides averaged 1.1 percent 

copper and 7.62 percent zinc. 

Fourth of July Creek - A three-pan placer sample (13167, map no. 63) of loose gravel 

from a test pit contained 0.0221 oz/cy (0.899 g/cu m) gold in ragged flakes. In addition, 

cinnabar and scheelite were observed in the concentrate. About 61,000 cy (47,000 cu m) 

of gravel were processed by placer miners at this site, but gold production is unknown. 

There was no indication that bedrock was reached. 

Independence Mine area - Rhyolite porphyry dikes exposed in recent bulldozer cuts 

near the Independence Mine contained 1 to 2 percent fine-grained pyrite and

arsenopyrite. Scorodite occasionally coats the fracture surfaces. One select sample from 

the dikes (13052, map no. 35) contained 1 ppm gold and 3,660 ppm arsenic. The dikes 

are up to 10 ft wide (3 m), but could not be traced for any distance due to extensive 

tundra cover. A select sample (13051, map no. 35) of quartz-bearing float from the adit 

dump contained 12.4 ppm gold. A select sample (13114, map no. 35) of quartz from the 

shaft dump contained 55.5 ppm gold, visible gold was occasionally observed in the 

quartz. 

Kaatz Prospect - This site is located 1 mi (2 km) west of the Independence Mine. A 

select sample (13120, map no. 38) of vuggy quartz float from a caved adit dump 

contained 1.6 ppm gold, 1,400 ppm lead, and 1,395 ppm arsenic. 

Little Creek - Rhyolitic rubblecrop was recently exposed by the property owner in a 300 

by 400 ft (90 by 100 m) placer cut on Six Pup, a northern tributary of Little Creek. The 

rhyolite contains quartz eyes, is propylitically altered, and occasionally cut by quartz 

veinlets. The rhyolite contained 1 to 2 percent pyrite and arsenopyrite; scorodite coats 

some fracture surfaces. Sample 13222 (map no. 18) contained 1.1 ppm gold and 1,800 

ppm arsenic. The rubblecrop configuration indicates a dike-like body at least 50 ft wide 

(15 m). 

Mackie Creek - A placer sample (13164, map no. 25) of gravel and underlying shale 

bedrock contained 0.019 oz/cy (0.77 g/cu m) of flaky, nuggety, and wire gold. The 

sample was collected near the upper limit of recent placer workings where bedrock is 

covered by 6 to 8 ft (1.8 to 2.4 m) of overburden. 

Moore Creek - Bench gravels having minimum dimensions of 100 by 400 ft (30 by 100 

m) on upper Moore Creek contain significant placer gold. Fractured shale bedrock is 

overlain by 2 to 3 ft (0.6 to 0.9 m) of cobble gravel. Five test pans, collected on bedrock, 

produced 1 coarse and 4 fine flakes of nuggety gold. A pan concentrate sample (13041, 

map no. 69) contained 18.8 ppm gold and 1,680 ppm barium. 

Nixon Fork (Mespelt Mill) tailings - A representative sample (13220, map no. 2) was 

collected from the historic Mespelt Mill tailings at the Nixon Fork Mine site. The sample 

was collected at 10 ft (3 m) intervals up the 50-ft-high (10 m) tailings dump and 

contained 1.13 oz/ton (38.7 g/t) gold and 2.32 percent copper. The dump dimensions 

average 25 ft thick (7.6 m), by 100 ft wide (30 m), by 200 ft long (60 m). A second 

random chip sample (13219, map no. 2) collected from chalcopyrite-rich ore at the portal 

of the Goldfields decline contained 1.67 oz/ton (57.3 g/t) gold and 4.43 percent copper. 

Roberts PGM - A gabbro dike, cutting interbedded limestone and chert, is traceable for 

950 ft (290 m) along a N. 40° W. trend near the headwaters of the Middle Fork of the 

Kuskokwim River. Widths vary from nearly 40 ft (10 m) on the south end to 10 ft (3 m) 

on the north. Near the south end the gabbro was coarse-grained, containing 10 to 15 

percent pyrrhotite and chalcopyrite in disseminations and stringer-like zones with minor 

serpentinite. To the north the body appears more sill-like, is heavily serpentinized, and 

nearly barren of sulfides. A series of four continuous chip samples (13277-80, map no. 
10

91) were collected near the south end, across a collective width of 35.5 ft (10.8 m). The 

samples contained a total weighted average of 0.97 ppm platinum, 1 ppm palladium, and 

3,980 ppm nickel. Other rock samples collected from the site (13275-76, 13284-85, map 

no 91) contained from 0.012 to 0.404 ppm platinum and from 0.009 to 0.547 ppm 

palladium. 

Telephone Hill (Tele) Prospect - Gossanous limonitic vuggy quartz breccia rubblecrop 

and float is exposed over a 16 by 25 ft (4.9 by 7.6 m) area along a ridge top. A select 

sample (13159, map no. 34) contained 7.9 ppm gold and 9,320 ppm arsenic. 

 

Terra-Fish Creek area - This area contained three distinct mineralized properties; Terra 

North, Terra-Fish Creek, and Terra South. A sample (13290, map no. 145) collected of a 

quartz-carbonate vein 6 to 12 in wide (20 cm to 0.3 m), hosted in shale and silty shale at 

Terra North, contained 23.57 oz/ton (808.1 g/t) silver, 6.71 oz/ton (230 g/t) gold, and 0.2 

percent arsenic. A similar vein, but hosted in monzonite, located at the Terra-Fish Creek 

site, 1 mi (2 km) north of Terra North, contained 7.64 oz/ton (262 g/t) silver and 6.97 

oz/ton (239 g/t) gold (sample 13293, map no. 144). Terra South is a gold in soil 

anomaly, located 2.3 mi (3.7 km) southeast of Terra North on a narrow ridge dividing the 

Fish Creek and Hartman River basins. A soil sample (13372, map no. 146) and a sample 

of fine talus material (13295, map no. 146) contained 0.055 oz/ton (1.9 g/t) and 0.035 

oz/ton (1.2 g/t) gold, respectively. 

Win - Samples collected from this property contained anomalous levels of silver, tin, 

arsenic, antimony, copper, and zinc. A select sample (13107, map no. 5) collected from a 

gossanous outcrop, on the west side near an abandoned drill site, contained up to 47.1 

oz/ton (1,610 g/t) silver, over 1 percent arsenic, 0.61 percent copper, 2.2 percent 

antimony, 3.9 percent tin, and 0.52 percent zinc. A sample (13106, map no. 9) collected 

of chloritic-altered sandstone rubblecrop with minor veinlets and disseminated grains of 

arsenopyrite contained 0.029 oz/ton (0.99 g/t) gold. A placer sample (13026, map no. 4), 

collected from a small north flowing stream draining the property, contained 0.01 oz/ton 

(0.3 g/t) gold, 0.42 oz/ton (14 g/t) silver, and 177 ppm tin.

SAMPLING AND ANALYTICAL PROCEDURES 

SAMPLING METHODS 

BLM personnel collected several types of rock samples during the 2003 field season. 

Continuous chip samples were chips of rock taken in a continuous line across an 

exposure. Representative chip samples were discontinuous chips of rock taken across 

an exposure. Spaced chip samples were chips of rock taken at a specified interval across 

an exposure. Random chip samples were chips of rock taken randomly across an 

exposure. Grab samples were rock chips or fragments taken more or less at random 

from an outcrop, float, or mine dump. Select samples were rock chips collected from the 

highest-grade portion of a mineralized zone. 

Stream sediment, soil, and pan concentrate samples were collected in reconnaissance 

fashion to detect any anomalous metal values that may indicate the presence of 

mineralized rock in an area. Stream sediment samples were collections of silt- and claysized particles taken from the active portion of the streambed. For each sample 

approximately 1 lb (0.5 kg) of material was collected using a 10-mesh sieve. Pan 

concentrate samples were collected in streams where heavy minerals might accumulate, 

such as stream gradient changes from steep to moderate, the downstream side of 

boulders, and/or on bedrock. A 14 in (35 cm) gold plan heaped with coarse gravel, sand, 

and/or fine material was panned down to approximately 0.75 oz (21 g) of concentrate. 

The presence of heavy minerals was noted in the field and the samples were stored in 

sealed plastic bags. 

Placer samples were collected using a portable 10 by 48 in (20 by 120 cm) sluice box. 

Samples typically consist of 0.1 cy (0.08 cu m) bank material run through the sluice box 

and panned down to produce approximately 2.5 oz (71 g) of concentrate. The samples 

were taken back to the BLM Campbell Tract Facility, Geology Lab where they were 

processed. All placer samples were air dried and all visible gold was segregated and 

weighed. The remaining concentrates were examined using a microscope, scintillometer, 

and ultraviolet light to determine the sample mineralogy. A split of, or the entire 

concentrate, depending on weight, was submitted and analyzed with the same methods as 

pan concentrate samples. 

Sluice concentrate samples were collected from active placer mine wash plants to 

identify accessory minerals such as cinnabar, arsenopyrite, cassiterite, and scheelite. 

These consisted of 1 to 2 lbs (0.5 to 0.9 kg) of black sands and other heavy minerals 

remaining after miners had removed the majority of the placer gold. The amount of 

gravel washed to produce the sluice concentrate was unknown. Metal contaminants such 

as lead battery fragments and shot were removed with a sieve. Then, similar to placer 

samples, the concentrate was then examined by microscope, ultraviolet lamp, and 

scintillometer in order to determine mineralogy before being submitted for chemical 

analysis.

ANALYTICAL METHODS 

This study, as with most BLM mining district studies, assesses metallic and non-metallic 

mineral occurrences. To analyze for elements of economic interest to our study, all 

geochemical samples were submitted to ALS Chemex Labs2

 of Vancouver, BC, Canada, 

via their Fairbanks, Alaska sample preparation facility. Samples were analyzed to 

anticipate a variety of needs when assessing the study area. Typical analysis for rocks 

and sediments was a 1.1 oz (31 g) Gold-Platinum-Palladium Fire Assay, then a 50 

element aqua-regia digestion with a combination of Induced Coupled Plasma-Mass 

Spectroscopy (ICP-MS) and ultra trace Induced Coupled Plasma-Atomic Emission 

Spectroscopy (ICP-AES) analysis. These analyses were followed by pressed pellet XRay Fluorescence Spectroscopy (XRF) analysis for barite, tin, and tungsten. Samples 

with assay results exceeding the detection limits of the typical analysis were reanalyzed 

by a variety of procedures dependent on which element exceeded the detection limits. 

More information about the details of the geochemical analyses of the project and ALS 

Chemex Labs analytical techniques can be found on the ALS Chemex Labs website:

Sample Preparation 

At the ALS Chemex Labs Fairbanks sample preparation facility the soil and stream 

sediment samples were kiln dried, dry sieved to less than 180 microns and split down to 

an 8.8 oz (273 g) sample. Rock samples were crushed so more than 70 percent of the 

material passed through a screen with 0.08 in (2 mm) openings, then split down to an 8.8 

oz (250 g) sample that was pulverized in a ring crusher until 85 percent passed through a 

75-micron screen. Pan concentrate, placer, and sluice concentrate samples were dried 

and pulverized without screening, then split down to meet the analytical tests needs. The 

placer and sluice concentrate samples were then prepared for analysis in the BLM 

Campbell Tract Facility, Geology Lab.

DETECTION LIMITS BY ANALYTICAL TECHNIQUE 

FIRE ASSAY METHODS 

All samples were fire assayed with either an ICP-MS finish (ALS Chemex Labs method 

code: PGM-MS23) if it was a soil or sediment sample or an ICP-AES finish (ALS 

Chemex Labs method code: PGM-ICP23) if it was a rock sample; to detect gold, 

palladium, and platinum. Suspected high-grade samples were noted on the sample 

submittal form and were analyzed using the same ICP-MS or ICP-AES methods but the 

instruments were calibrated to higher detection limits (ALS Chemex Labs method code: 

PGM-MS27 and PGM-ICP27). Samples with gold and silver assay results that exceed 

their respective ICP analysis detection limits, at the discretion of the lab, were reanalyzed 

by fire assay with either a gravimetric finish (ALS Chemex Labs method code: AgGRA21 and Au-GRA21), or by Atomic Absorption Spectroscopy (AAS) (ALS Chemex 

Labs method code: Ag-AA46 and Au-AA25).

INDUCTIVELY COUPLED ARGON PLASMA (ICP) SPECTROSCOPY 

After the fire assay, a split of the sample pulp was partially dissolved in aqua-regia. The 

resulting solution was analyzed using a combination of ICP-MS and ICP-AES (ALS 

Chemex Labs method code: ME-MS41).

ATOMIC ABSORPTION SPECTROSCOPY (AAS) 

AAS analysis, an analytical technique where elements, dissolved in solution and excited 

by intense heat were detected by the amount and selectivity of the light absorbed from a 

constant beam shining through the hot vapor. AAS was used for samples when nonprecious metals of economic interest were over the ICP analysis detection limits. 

Elements of interest were antimony, arsenic, cadmium, copper, lead, mercury (cold vapor 

atomic absorption), nickel, and zinc.

X-RAY FLUORESCENCE SPECTROSCOPY (XRF) 

Because barium, tin, and tungsten were resistant to the aqua-regia used in the ICP 

process, all samples, except pan concentrate and placer samples, were analyzed by XRF 

for those elements (ALS Chemex Labs method code: ME-XRF05).

RESULTS OF PLACER AND SLUICE CONCENTRATE SAMPLE 

EVALUATION FOR THE 2003 FIELD SEASON 

Table 1 presents the results of placer and sluice concentrate sample processing at the 

BLM Campbell Tract Facility, Geology Lab. Samples were dried and sieved and the 

coarse gold removed. Recoverable gold was weighed, measured, and described and an 

accurate count of the number and size of the gold particles was recorded. Remaining 

sample material was then examined with a microscope, noting any other conspicuous 

metals and minerals. Samples were also tested with a shortwave ultraviolet lamp to 

identify any scheelite, zircon, or other fluorescent minerals and then tested for 

radioactivity with a scintillometer. A split of the sample was sent in for chemical 

analyses and the remainder of the sample was archived. The results of the geochemical 

analysis are presented in Table 2. 

The “Au weight (g)” column presents the weight, in grams, of gold after the separation 

from each placer concentrate. As much gold as possible was removed from the samples 

using tweezers. Any gold that was too fine to be removed manually was included in the 

analytical results from the geochemical analysis of material sent to the commercial 

laboratory. No attempt was made to determine the gold fineness values from the samples 

collected. 

Map numbers correspond to the numbered locations shown on plate 1.
