MINERAL INVESTIGATIONS IN THE ANIAK MINING 

DISTRICT, SOUTHWESTERN ALASKA, 

2004 FIELD SEASON 

ABSTRACT 

The Aniak Mining District study focuses on the evaluation of mineral resources in a 

large, approximately 27 million-acre (11 million hectares) area of southwestern Alaska, 

expanded to include parts of the adjacent Anvik, Iditarod, Innoko, Marshall, and 

McGrath Mining Districts. Fieldwork for the district evaluation will be completed in 

three years and followed by the publication of a comprehensive, district-wide report in 

year four. The second season of the three-year field investigation was completed in 

2004 by the Bureau of Land Management (BLM), Alaska State Office, Solid Minerals 

Branch. 

The 2004 field investigation examined properties in the central one-third of the district, 

which includes the gold occurrences at Donlin Creek and Flat, in addition to placer and 

lode prospects in the Napaimiut, Taylor Mountains, Fortyseven Creek, and George 

River areas. The historic DeCourcy Mountain and Red Devil area mercury deposits, as 

well as placer gold occurrences along the Oskawalik River, were investigated. A 64-

sample soil survey grid completed in the Eagle Creek area followed-up reconnaissance 

data provided by Calista Corporation. In all, 86 mineral occurrences were evaluated 

and 290 samples collected during the 2004 Aniak Mining District mineral investigation.

INTRODUCTION 

In 2004, the BLM-Alaska, Division of Energy and Solid Minerals, Solid Minerals 

Branch completed the second year in a four-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 based on potentially economic mineral deposits in 

the district; and fund geophysical investigations of areas having the potential to contain 

concealed mineral deposits. BLM fieldwork 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 study is part of the Alaska Minerals program,

which conducts mineral assessments on public lands as authorized under Section 1010 

of the Alaska National Interest Lands Conservation Act. 

The Aniak Mining District project area 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. Historically, placer gold has been the main commodity sought in the 

district, with reported production as early as the late 1800’s. Platinum and mercury 

placers, as well as gold and mercury lodes 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

The BLM began the multi-year mineral resource assessment of the Aniak Mining 

District in 2003 by examining the northeastern part of the district.2

 BLM geologists 

located, mapped, and/or sampled 100 documented sites in the northeastern part of the 

study area, collecting and analyzing 351 rock, pan concentrate, stream sediment, soil, 

and placer samples. Sites investigated in 2003 included, Fourth of July Creek, Ganes 

Creek, Moore Creek, and Nixon Fork. 

This report presents analytical results for samples collected during the 2004 field 

season and provides a brief description of findings for selected mineral sites. A final 

report detailing the results of BLM’s Aniak Mining District mineral assessment, 

including property summaries and all analytical data, will be published in 2006. An 

economic analysis report and an industrial minerals report will also be published in 

2006.

2004 FIELD SEASON REVIEW 

The 2004 summer field season began in the second week of June with team members 

mobilizing to Mellick’s Lodge on the Kuskokwim River near Sleetmute. While based 

at Mellick’s, the mineral assessment team completed a 35-day evaluation of sites in the 

Kuskokwim Mountains (Plate 1). Work focused on property examinations and sample 

collection in the central portion of the district, specifically the Iditarod and Sleetmute 

quadrangles. The majority of those sites evaluated during 2004 were visited during this 

time, including: the Flat-area prospects such as Chicken Mountain, the Golden Horn 

Mine, and Happy Creek; the Ruby Gulch placer mine and the ongoing Donlin Creek 

lode gold project at Donlin Creek; the Red Devil-area mercury occurrences; and other 

scattered sites from Hill Top No. 1 in the north, to Girl Creek in the south. A 64-

sample soil grid was completed in the Eagle Creek area near Crooked Creek, in followup of reconnaissance data provided by Calista Corporation. 

2004 was a record-setting year for Alaska. In addition to a banner year for mosquitoes 

(according to locals) in the Kuskokwim region, Interior Alaska fires set a new record 

for acres burned. Final statistics for the 2004 fire season, the worst in Alaska’s modern 

history, include 655 fires responsible for over 6,000,000 million acres (2,400,000 

hectares) burned. The fires impacted the Aniak mineral assessment program through 

reduced visibility and eventually, on July 6th, by a re-assignment of the project 

helicopter to assist with fire-suppression activities near Fairbanks. 

After a short hiatus, mineral assessment activities resumed in the first part of August. 

A two-person crew was mobilized to Fortyseven Creek by fixed-wing aircraft, and 

spent two days examining placer and lode occurrences in the Fortyseven Creek area. 

Following a short flight to the Taylor Mountain airstrip, the Taylor Creek and Taylor 

Mountain West placer gold occurrences were examined. A total of three days were 

spent in the Taylor Mountains area. USGS geologists who were sampling and mapping 

in the area provided short helicopter moves for Aniak study crew members during this 

time. This support enabled sampling in outlying areas such as Kiknik and Whitewater 

Creeks prior to the completion of the Aniak Mining District 2004 field season. 

Pre-field season literature searches identified over 140 mineral sites/occurrences in the 

2004 study area. However, due to abbreviated helicopter support that effectively 

reduced the intended seven-week field season to five weeks, approximately 30 sites 

located in the eastern portion of the planned 2004 study area were not visited. This 

eastern portion consists of sites in the Lime Hills, Lake Clark, and Taylor Mountains 

quadrangles, areas now included in the planned 2005 study area. During the 2004 

Aniak Mining District investigation, a total of 86 mineral occurrences were located and 

evaluated, with 290 samples collected. Numerous sites with elevated metal values or 

other noteworthy results were documented; the following provides a brief description of 

significant findings for selected mineral sites: 

Ahgaluk: A 2-pan concentrate sample (13609, map no. 165), collected from an eastnortheast flowing stream on the border between sections 23 and 14, contained 0.132 

4
ppm gold, 143.5 ppm arsenic, and 2.58 ppm antimony. Two very fine-grained gold 

particles were also recovered in the sample. Stream float consisted of 60% sandy shale 

with rare quartz veinlets and 40% (very) fine-grained felsic intrusive with minor quartzfeldspar phenocrysts. The site is located on State lands. 

Barometer Mine: A grab sample (13478, map no. 150) of surface float, or possibly 

dump material, was collected at the Barometer Mine’s collapsed portal. The sample, 

consisting of a single, thin <1 in (2.5 cm) quartz-stibnite-cinnabar veinlet cutting 

brecciated and hornfelsed Kuskokwim Group shale, contained 0.933 ppm gold, 3.19 

ppm silver, 8.08% antimony, and 3,030 ppm mercury. The site is located on Calista 

Corporation lands. 

Chicken Mountain: Placer workings and trenching near the head of Flat Creek (Idaho 

Bench) on the north side of Chicken Mountain expose deeply-weathered quartz 

monzonite of the Chicken Mountain Stock. The monzonite is cut by limonite-stained, 

widely-spaced stockwork quartz veinlets and silicified shear zones. A select sample 

(13507, map no. 10) of a 2 in (5.3 cm) wide quartz veinlet contained 30.6 ppm gold, 

77.9 ppm silver, 5320 ppm arsenic, and 432 ppm antimony. A spaced-chip sample 

(13509, map no. 13509) across a 9.8 ft (3 m) wide limonitic silicified shear zone, 

contained 13.4 ppm gold, 1,405 ppm arsenic, and 78 ppm antimony. Pans of limonitestained, grus-like monzonite from the same site contained visible gold, and a pan 

concentrate (13508, map no. 10) contained 51.4 ppm gold. The site is located on 

Doyon Ltd. lands. 

On the south side of Chicken Mountain, near the headwaters of Chicken Creek, 

trenching in saprolitic monzonite and syenite has exposed stockwork quartz veinlets up 

to 0.5 inch (1.0 cm) wide. The veinlets exhibit potassic alteration halos and contain 

disseminated arsenopyrite. A select sample (13368, map no. 13) of syenite trench float 

contained 2.4 ppm gold and 1.09% arsenic. Veinlet concentration in the trenches 

averaged about 1 every 10 ft (3.0 m). A 2-pan concentrate of monzonite grus, exposed 

in a placer cut at the head of Chicken Creek (13370, map no.14) contained 50.2 ppm 

gold. The site is located on active Federal mining claims. 

DeCourcy Mountain: A grab sample (13540, map no. 112) from an ore stockpile, 2.0 

mi (3.2 km) south of the summit of DeCourcy Mountain, contained 0.194 ppm gold and 

1.04% antimony. A continuous chip sample (13541, map no. 113) across a 0.5 ft (0.15 

m) wide zone of cinnabar-bearing quartz veinlets, contained 0.244 ppm gold and 107 

ppm antimony. The chip sample was collected in a trench 1.6 mi (2.6 km) south of the 

summit of DeCourcy Mountain. The site is located on Calista Corporation lands. 

Eightmile Creek: Pans from stream gravel on Eightmile Creek, 1.9 mi (3.1 km) 

upstream from the Kuskokwim River, contained trace visible gold. A 4-pan concentrate 

(13548, map no. 144) collected at the same site, contained 0.315 ppm gold, 45.2 ppm

arsenic, 10.65 ppm antimony, and 2.05 ppm mercury. Stream float contained minor 

amounts of rhyodacite porphyry and felsite (?). There are no bedrock exposures near 

5
the sample site. No signs of placer mining or sampling were observed in the drainage.

The site is located on Calista Corporation lands. 

Georgetown Prospect: Quartz-stibnite-cinnabar veins up to 8 in (20.3 cm) thick are 

exposed in Hill 1273 area trenches. Veining generally consists of quartz-healed 

Kuskokwim Group shale and graywacke breccias, with minor drusy quartz and open 

space. Two select samples (13480-81, map no. 130) collected from the trenches 

contained up to 28.2 ppm gold, 116 ppm silver, 27.4 ppm arsenic, 44.2 ppm mercury, 

and 1.04% antimony. Quartz vein material comprised approximately 1% of talus in a 

60 ft (19.5 m) wide, at least 600 ft (185 m) long zone, which trends east-west across 

main trenched area. A caved adit appears to have tested the zone from the north, 

although no quartz vein material was found in dump material near the collapsed portal. 

Thin felsic dike rocks up to 2 inches thick were observed in trenches and surface float. 

The Georgetown Prospect is located on lands selected by Calista Corporation. 

A select sample (13008) of vein quartz float and wallrock was collected near the 

trenches during a reconnaissance of the Aniak Mining District in 2001. The sample 

contained 2.2 ppm gold, 22.4 ppm silver, 18 ppm arsenic, 8.15% antimony, 11,478 ppm 

tin, and 267 ppm tellurium. The quartz vein float is associated with a 10-ft wide (3-m) 

wide quartz vein zone traced for 500 feet (152 m) from the caved adit to the northeast. 

Girl Creek: A 2-pan concentrate sample (13397, map no. 175) was collected from

Girl Creek, a western tributary of the Holukuk River. Stream float was exclusively 

Kuskokwim Group siltstone and sandstone. The sample contained one very fine gold 

grain, with analysis results of 0.923 ppm gold and, 147.5 ppm arsenic. The site is 

located on State lands. 

Golden Horn Mine: Samples were collected at the Golden Horn Mine site, 2.5 mi (4.0 

km) east of Flat. A select sample (13504, map no. 8) of arsenopyrite-bearing, quartzcarbonate vein material on the Golden Horn shaft dump contained 151 ppm gold, 395 

ppm silver, 5.04% arsenic, 1,235 ppm antimony, 40 ppm tungsten, and 19.2 ppm

mercury. A select sample (13502, map no. 8) of narrow quartz veins in a nearby trench 

contained 3.81 ppm gold and 4,100 ppm arsenic. A select sample (13505, map no. 8) 

of vein quartz float in a trench located 0.2 mi (0.32 km) southwest of the shaft 

contained 3.45 ppm gold, 47.8 ppm silver, and 19.7% antimony. The Golden Horn is 

located on active Federal mining claims. 

Happy Creek: Eluvial placer gold was found near the upper limit of old placer 

workings in a broad sloping area at the headwaters of Happy Creek, on the west side of 

Chicken Mountain. A placer sample (13382, map no. 11) collected from fractured 

monzonite bedrock contained 0.056 oz/cy (2.28 g/cu m) or 0.0004 oz (0.012 g) of 

gold/bedrock foot. The gold was mostly nuggety with rare dendritic pieces. Cinnabar 

and scheelite were observed in the resulting concentrate. Overburden at the head of the 

placer cut averaged about 6 ft (1.8 m) thick and contained boulders up to 3 ft (0.9 m) in 

diameter. There is potential for more eluvial placer resources upslope from the mined 

6
area, but getting water to the site for processing may be difficult. Nearby lode gold 

occurrences have been trenched and drilled. The site is located on Doyon Ltd. lands 

Kiknik Creek: A stream sediment sample (13424, map no. 191) collected from Kiknik 

Creek, west of the Taylor Mountains, contained 0.192 ppm gold. A pan concentrate 

sample (13423, map no. 191) was collected from gravel at the same site, yielding 28 

very fine gold grains and an assay result of 5.55 ppm gold. Stream float consists of 

Kuskokwim Group shale and mudstone with up to 25% felsic intrusive fragments. The 

site is located on State lands. 

Munther Creek: Munther Creek is a 3.5 mi (5.6 km) long western tributary to the 

East Fork of the George River. Pan concentrate and stream sediment samples were 

collected from sandy fluvial material about 1 mi (1.7 km) upstream from the George 

River. A 1-pan concentrate (13520, map no. 34) contained 1.13 ppm gold and 10.6 

ppm arsenic. At the sample point, the stream channel is deeply incised and meandering. 

The area is mostly tundra covered with no bedrock exposed in the vicinity of the 

sample site. No indications of placer mining or sampling were observed in the 

drainage. Munther Creek is located on State-selected lands. 

Red Devil Mine: Mineralized stream and surface float samples (13473, 13551; map 

no. 151) were collected at the former Red Devil Mine site. These select samples of high 

grade mineralization at the site contained greater than 10% mercury, and up to 22.3% 

antimony and 0.354 ppm gold. The mine site has been the focus of ongoing BLMmanaged mine reclamation activities which began in 1989. The following link presents 

a summary of Red Devil Mine reclamation activities: 

http://www.ak.blm.gov/ado/redevl-c.html. The site is located on Calista Corporation 

lands. 

Ruby Gulch placer: Continued placer gold development in the Donlin Creek area has 

focused on processing material near the mouth of Ruby Gulch. In 2004, the mining of 

a 150,000 sq ft (14,000 sq m) cut was completed and initial development of an 

additional 100,000 sq ft (9,200 sq m) cut was begun. A 0.1 cy (0.76 cu m) placer 

sample (13535, map no. 47) was collected adjacent to the developing cut. The sample 

consisted of 1 ft (0.03 m) of fractured bedrock and 0.5 ft (15 cm) of overlying bench 

gravel, yielding 0.039 oz/lcy (0.0007 oz/bedrock ft) gold. Gold particles varied from

rounded to dendritic up to 0.28 in (7 mm) in size. The sample contained minor 

cinnabar and trace scheelite. Overburden is up to 10 ft (3 m) thick. The site is 

currently under lease from Calista Corporation to a private individual. 

Ruby Gulch lode: Gold-bearing quartz-carbonate veins and altered dikes cutting 

Kuskokwim Group siltstone and graywacke were mapped in the recently completed 

Ruby Gulch placer cut. A northeast-striking dike zone, exposed in the placer cut for a 

distance of 190 ft (57.9 m), is offset by a series of east-west and north-south trending 

faults. The 10-ft wide (3.0 m) dike zone includes individual clay-sericite-fuchsite 

altered dikes up to 3 ft (0.9 m) wide which contain very fine needle-like grains of 

arsenopyrite (?) and trace pyrite. A grab sample (13526, map no. 47) of in-place dike 

7
material contained 0.595 ppm gold and 7,990 ppm arsenic. The dikes likely represent a 

mafic phase described in the main Donlin Creek lode gold project resource area located

1.9 mi (3.1 km) to the east. Quartz-carbonate veins up 4 in (10 cm) thick occur locally 

along the southeast margin of the dike zone. A select sample (13525, map no. 47) of a 

2-in wide (5.1 cm) vein contained 44.8 ppm gold, 1.37% arsenic, 1,925 ppm antimony, 

and 5.44 ppm mercury. 

Sheet-like sets of quartz veinlets were mapped by Aniak assessment team in zones 

outboard of the mapped altered dikes. The zones contain up to 1 veinlet per foot across 

widths of 10 ft (3 m), and strike for up to 100 ft (30.5 m) at an average N50°E. 

Individual veinlets typically 1 in (2.5 cm) thick contained up to 5% finely disseminated 

arsenopyrite and pyrite concentrated mainly along veinlet margins. Samples (13527-

28, continuous chip; 13530, spaced chip; 13539, select; all map no. 47) collected from

four separate quartz veinlet zones averaged 21.07 ppm gold, 9,917.5 ppm arsenic, and 

26.28 ppm mercury. One sample contained up to 32.5 ppm gold (13527, map no. 47). 

The Ruby Gulch lode area is covered by an exploration lease granted to the Donlin 

Creek lode gold project by subsurface-estate owner Calista Corporation. Predevelopment economic feasibility studies are currently underway for the Donlin Creek 

lode gold project as a whole. 

Taylor Mountain West Placer: A 2-pan concentrate sample (13606, map no. 189) 

collected from the active Taylor Mountain West Placer operation contained 40 to 60 

very fine to fine colors, equivalent to 0.17 oz/cy (6.92 g/cu m). The majority of gold 

occurs as very angular to dendritic grains, with few rounded particles, suggesting a 

nearby source. The sample contained a moderate amount of black sands, with abundant 

wolframite and only minor magnetite and scheelite. Quartz grains recovered exhibited

black, needle-like tourmaline intergrowths. The sample was collected from basal pay 

gravels, just above bedrock exposure of gray Kuskokwim Group siltstone. Analysis of 

the concentrate after removal of visible gold yielded 305 ppm gold, 60.1 ppm silver, 

267 ppm mercury, 820 ppm tungsten, and 2,350 ppm tin. The Taylor Mountain West 

Placer is covered by active State mining claims. 

Whitewater Creek: Two samples were collected from Whitewater Creek, a lowgradient tributary of Kiknik Creek that drains the west side of the Taylor Mountains. A 

stream sediment sample (13426, map no. 190) contained 1,395 ppm gold and a two-pan 

concentrate sample (13425, map no. 190) resulted in 2.25 ppm gold. Six very fine 

colors observed in the pan concentrate were accompanied by pink garnets and very few 

heavy mineral grains. Stream float in the drainage consists of Kuskokwim Group 

graywacke and shale, with up to 25% felsic intrusive fragments. The site is located on 

State lands.

 SAMPLING AND ANALYTICAL PROCEDURES 

SAMPLING METHODS 

Samples of geologic materials - soil, sediment, and rock - were collected using a variety 

of methods during field investigations. A description of sampling methods utilized for 

the 2004 field season is presented below. 

Rock samples are of seven types: (1) grab - samples consist of small rocks or rock 

fragments collected more or less at random from surface float, an outcrop, or mine 

dump; (2) select – rock fragments taken from the most-mineralized portion of a 

mineralized zone in order to estimate the highest grade potential; (3) random chip – 

rock chips taken randomly across an exposure; (4) representative chip – samples 

consist of rock fragments chipped at random across any exposure; (5) spaced chip - 

samples of rock chips collected at a specified interval across an exposure and reported 

with a corresponding distance and chip frequency measurement; (6) continuous chip - 

samples consist of small rock fragments chipped in a continuous line across an 

exposure and were usually reported with a corresponding distance measurement; and 

(7) chip channel –a channel sample, typically 4 in (10 cm) wide by 2 in (5 cm) deep 

across a specified distance, was chiseled from an exposure in order to better 

volumetrically represent sampled material, when possible. 

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

mode to detect geochemical values, specifically metals, which indicate the presence of

mineralized rock in an area. Additionally, pan concentrate samples were applied as a

placer deposit evaluation tool when other sample methods are impractical. Stream 

sediment samples consist of clay- to sand-sized particles collected from an active 

streambed. The coarse fraction was removed using a 10 mesh (2.0 mm) sieve and for 

each sample approximately 1 lb (0.5 kg) of fine material was collected. Pan 

concentrate samples represent the dense, heavy minerals contained in a stream’s 

sediment load. Often these samples are collected at locations where heavy minerals 

might accumulate, such as where stream gradient changes from steep to moderate, the 

downstream side of boulders, or on bedrock. A 14 in (35 cm) gold plan heaped with 

stream sediment (gravel and fines) was panned down to approximately 0.75 oz (21 g) 

of concentrate. Often, two or more pan concentrate samples were combined and 

submitted as a single, 0.75 oz (21 g) sample. A visual description of sample 

mineralogy was noted in the field, and the sample was stored in a sealed plastic bag 

prior to laboratory submittal. 

Soil samples were collected with a stainless steel hand auger or shovel. Approximately 

0.5 lb (220 g) sample was collected from as deep as possible, typically 18 to 24 in 

below the surface, before hitting the permafrost (frozen) soil. Samples were collected 

from below the organic layer in the ‘C’ soil horizon, the subsoil closest to bedrock that 

often contains rock fragments. C horizon material is the standard sample material in 

9
soils subject to permafrost. Samples were stored in paper geochemical sample bags and 

allowed to dry before shipment to the analytical laboratory. Sample tools were cleaned 

between sample sites. 

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) of 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 geology laboratory at BLM’s Campbell Tract Facility 

where they were processed. Lab-processing includes washing, air drying, weighing of 

the entire sample, removal of magnetic component (i.e. tramp iron and magnetite), and 

the segregation and weighing of all visible gold. The remaining concentrate was 

examined using a binocular microscope, scintillometer, and ultraviolet light to 

determine sample mineralogy. A split of the sample, or entire sample if less than about 

1.75 oz (50 g), was typically submitted and analyzed with the same analytical methods 

used for pan concentrate samples. 

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

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

These consisted of 1 to 4 lbs (0.5 to 1.8 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 typically unknown. Samples were 

taken back to the geology laboratory at BLM’s Campbell Tract Facility and processed 

in much the same way as placer samples. Coarse, metal contaminants such as lead 

battery fragments and shot are removed with a sieve. The samples were washed, air 

dried, the magnetic component was removed, sample weight was then recorded, and 

finally, visible gold was segregated and weighed. The remaining concentrate was 

examined using a binocular microscope, scintillometer, and ultraviolet light to 

determine sample mineralogy. A split of the sample, or entire sample if less than about 

4 oz (125 g), was typically submitted and analyzed with the same analytical methods 

used for pan concentrate samples. One sluice concentrate sample (13532) was 

additionally sieved into seven grain size fractions to determine gold particle size 

distribution. 

ANALYTICAL METHODS 

This study, as with most BLM mining district studies, assesses metallic and nonmetallic mineral occurrences. To analyze for elements of economic interest to our 

study, all geochemical samples were submitted to ALS Chemex Labs3

 of Vancouver, 

BC, Canada, via their Fairbanks, Alaska sample preparation facility. Samples were 

analyzed for a comprehensive analytical package in anticipation of a variety of 

assessment goals and requirements. Typical analysis for rocks and sediments was a 1.1 

oz (31 g) gold-platinum-palladium fire assay, followed by a 50 element aqua-regia 

digestion, and 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 X-ray fluorescence 

spectroscopy (XRF) analysis for barite, tin, and tungsten. Samples with assay results 

exceeding element-specific detection limits for the standard analysis were reanalyzed 

by a variety of element-specific procedures. 

More detailed information about specific geochemical analyses and analytical 

techniques can found at the ALS Chemex Labs website: http://www.alschemex.com

Sample Preparation 

At ALS Chemex Labs sample preparation facility in Fairbanks, Alaska, 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 volume 

specification, according to specific testing needs.

DETECTION LIMITS BY ANALYTICAL TECHNIQUE 

FIRE ASSAY METHODS 

For gold, palladium, and platinum analysis, all soil and sediment samples were fire 

assayed with an ICP-MS finish (ALS Chemex Labs method code: PGM-MS23) and all 

rock samples were subjected to an ICP-AES finish (ALS Chemex Labs method code: 

PGM-ICP23). Suspected high-grade samples were noted on the sample submittal form

and analyzed using the same ICP-MS or ICP-AES methods, but with instruments 

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 were, at the discretion of the lab, reanalyzed by fire assay 

with either a gravimetric finish (ALS Chemex Labs method code: Ag-GRA21 and AuGRA21), or by atomic absorption spectroscopy (ALS Chemex Labs method code: AgAA46 and Au-AA25).

ATOMIC ABSORPTION SPECTROSCOPY (AAS) 

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

excited by intense heat, are detected by the amount and selectivity of light absorbed 

from a constant beam shining through the hot vapor. AAS was used for samples when

non-precious metals of economic interest exceeded 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 are 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 PROCESSING, 

ANIAK MINING DISTRICT STUDY, 2004 FIELD SEASON 

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

BLM Campbell Tract Facility geology laboratory. Samples were first sieved, dried, 

and any extraneous material (e.g. tramp iron, steel/lead shot was removed). After 

weighing the clean, dry sample, magnetic sand, such as ilmentite and magnetite, were 

removed and examined. Finally, coarse gold was removed, described, weighed, and an 

accurate count of the number and sizes of gold recovered particles was recorded. 

Remaining sample material was then examined with a microscope, and conspicuous 

metals and minerals were noted by percentage. 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. When sufficient sample 

volume existed, a split of the sample was sent in for chemical analysis and the 

remainder of the sample was archived. If sample volume was insufficient for splitting,

the entire sample volume was submitted to the lab for analysis. 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 on Plate 1.
