Geologic description:

 Most of the gold is in a bench placer in the lower mile of the creek where there is a 

well-defined bench 150 feet above the creek on its north side. Above this bench, about 

400 feet in elevation above the creek, an old channel on the spur between the main branch 

and the south fork of Quail Creek shows colors (Mertie, 1934). Concentrates contain picotite, cassiterite, barite, scheelite, pyrite, garnet, gold, zircon, rutile and one grain of cinnabar (Mertie, 1934; Waters, 1934). Bedrock is slaty shale with many quartz veinlets 

and small porphyry dikes (Prindle and Hess, 1905). Bench and/or creek placers were 

mined sporadically from 1898 to as recently as 1940 (Cobb, 1976; OFR 76-633). No data

Geologic description:

 Mertie (1918, p. 256), reported that most of the mining occurred along the old channel 

from bench claims northwest of Livengood Creek. The old channel has an average width 

of 127 feet, an average depth to bedrock of 80 feet, and at the time of Mertie's report, had 

been traced for approximately 4 miles. The bedrock is mainly chert, with some greenstone and limestone. Gold is found in basal gravel and weathered bedrock. Concentrates 

contain gold, magnetite, ilmenite, limonite, picotite, hematite, barite, and pyrite. 

 By 1939, a large auriferous bench that occupied the northwest limit of Livengood Creek 

valley was defined (Bundtzen and others, 1982).

Production Status: Yes; large 

Site Status: Active 

Workings/exploration:

 Placer mining has taken place from 1914 to the present. Much of the development and 

production had been confined to relatively shallow pay in tributaries of Livengood Creek. 

By 1939, a large auriferous bench that occupied the northwest limit of Livengood Creek 

valley was defined (Bundtzen and others, 1982). This bench was covered by 80 to 110 

feet of muck but because the pay streaks were thawed, extensive drift mining was not 

possible. A larger company, Livengood Placers, was formed to develop these bench deposits, which vary from 100 to 1,000 feet in width and extend for at least 6 miles 

(Bundtzen and others, 1982). Gold reserves of over 1 million ounces were defined by 

drilling prior to 1940. A dredge operated near the town of Livengood in 1940, 1946 and 

probably other years (Cobb, 1976; OFR 76-633, p. 115). In the winter of 1981, Livengood Joint Ventures (LJV), a consortium of Asamera Minerals, Canadian Natural Resources, and Stanford Mines of Canada and the United States, contracted Doyon, Ltd., to 

strip overburden from the bench and construct a large settling pond; both projects were 

completed in June, 1981 (Bundtzen and others, 1982). Annual production from 1978 t0 

1981 varied from 800 to about 3,000 ounces of gold (Bundtzen and others, 1982). The 

washing plant for this operation consisted of two sluice boxes fed by a dozer or front-end 

loader. By 1981, a large washing plant was acquired. Alaska Placer Development reported mining activity on the Livengood bench in 1988, 1994, 1996 and 1997. In 1994, a 

crew of 8 to 10 processed approximately 156,000 cubic yards of auriferous pay using 

opencut-hydraulic mine technology (Swainbank and others, 1995, p. 28). In 1996, Alaska 

Placer Development conducted a vigorous exploration program to ascertain the full extent 

of the pay zone (Swainbank and others, 1997). 

Production notes:

 Placer mining has taken place from 1914 to the present; however, exact production figures are not available. Annual production from 1978 to 1981 varied from 800 to about 

3,000 ounces of gold (Bundtzen and others, 1982). In 1994, a crew of 8 to 10 processed 

approximately 156,000 cubic yards of auriferous pay using open cut-hydraulic mine technology (Swainbank and others, 1995, p. 28). 

Reserves:

 Gold reserves of over 1 million ounces were defined by drilling prior to 1940 (Bundtzen 

and others, 1982). One reserve estimate based on data from 640 drill holes indicates 

about 17 million cubic yards of placer gravel that would average about $2.10 per cubic 

yard in gold at its 1976 price (Eberlein and others, 1977, p. 67).

Geologic description:

 Gold is found at the base of the gravels and in the top 2 feet of bedrock with a paystreak 

30 to 40 feet wide (Mertie, 1918). Black crystalline limestone with calcite and quartz 

veins slopes away from the creek on both sides (Mertie, 1918). Gold was reportedly high 

grade, netting $18/oz after charges (Mertie, 1918). Placer mining took place from as early 

as 1916 to as late as 1940 (Cobb, 1976; OFR 76-633). Concentrates contain gold, 

scheelite, magnetite, cinnabar, chromite, pyrite, arsenopyrite, zircon, monazite, chrome 

spinels and stibnite (Cobb, 1976; OFR 76-633, p. 164-166).

Geologic description:

 Gold occurs in all the gravels and the top foot of bedrock in both bench and stream 

placers (Mertie, 1918). Placers were being worked from 4 to 30 feet deep, with most of 

the gold in low benches. Gold is angular and coarse. Concentrates contain gold, magnetite, ilmenite, picotite, limonite, cinnabar, scheelite, zircon, pyrite, stibnite, and barite 

(Mertie, 1918). The bedrock surface is very irregular and pitches steeply down the creek 

(Overbeck, 1920). Mining began in 1915 and was being carried on as recently as 1988 

(Cobb, 1976; OFR 76-633, p. 111; Green and others, 1989).

Geologic description:

 Trenching near the head of Olive Creek has exposed narrow, northwest-trending auriferous arsenopyrite-quartz veins in ferruginous quartzite near the intersection of an altered, 

porphyritic, biotite-monzonite dike, and a potassium feldspar-porphyry dike (Foster, 

1968). Mineralization at the Old Smoky prospect is in Devonian sedimentary rocks composed of shale, argillite, fine-grained sandstone, and pebbly conglomerate (Allegro, 1984, 

p. 3). Narrow zones of thermal metamorphism occur along sheared contacts between 

these sedimentary rocks and hypabyssal igneous intrusive rocks (Allegro, 1984, p. 3). 

Similar felsic intrusive rocks throughout the Livengood Quadrangle have been potassiumargon dated at 58.0 to 88.8 m.y. (Turner and others, 1975). 

 Most of the intrusive rocks and some of the sedimentary host rocks have experienced 

variable degrees of metasomatic hydrothermal alteration followed by lower temperature 

supergene alteration (Allegro, 1984, p. 4). Allegro (1984) described four types of hydrothermal Alteration: 1) silicification, as partial to complete replacement of the host 

rock by a dense network of quartz veinlets generally localized along contacts between the 

intrusive and sedimentary rocks; 2) sericitization, as fine- to medium-grained white mica 

in selvages along quartz veins, as anastomosing sericite-opaque mineral veinlets, and as 

patchy to massive sericitic replacement of feldspar, ferromagnesium minerals and quartz; 

3) deposition of trigonal nets of needle-like rutile often associated with secondary quartz 

and minor feldspar; and 4) epidote +/- sericite as a replacement of calcic plagioclase and 

ferromagnesian minerals resulting in massive aggregates, pseudomorphs, veins, and vug

fillings of epidote commonly associated with sericite, opaque minerals, and quartz. 

 Allegro's (1984) investigation and sample data reveal that the mineralization in the 

southern portion of the cut is localized along the contact zones between the biotite monzonite and the surrounding sedimentary rocks, and along a contact between biotite monzonite and feldspar porphyry. Channel and chip samples of arsenopyrite-stibnite quartz 

veins from these zones contained 1.0 to 29.8 ppm gold. Selected samples from the prospect contain 3 to 13 ppm gold as determined by atomic absorption, and 1.6 to 7.0 ppm 

gold as determined by fire assay-atomic absorption (Foster, 1968, p. 2). 

 Adjacent to the sheared contact zone, the intrusive rocks are either highly silicified with 

abundant rutile and some epidote, sericite, arsenopyrite, and monor stibnite, or contain 

epidote with sericite, rutilated quartz and arsenopyrite (Allegro, 1984, p. 6). Other rocks 

from the contact zone show intense supergene effects such as clay alteration, covellite and 

iron-oxides. In some cases these zones contain gold. Green scorodite is present throughout the mineralized areas. 

 In the northern section of the prospect, the most abundant mineralization is located 

along the contact area between the feldspar porphyry and a roof pendant of sandstone and 

shale (Allegro, 1984). A massive 1-meter-wide stibnite lens surrounded by a bleached 

sericite zone occurs along the northern contact of the roof pendant. Channel samples 

along this contact zone range from 0.5 to 4.3 ppm gold (Allegro, 1984, p. 6). Some gold 

is also associated with saprolitic zones in all the intrusive phases but these zones are not 

limited to shear zones or contacts (Allegro, 1984, p. 6). 

Alteration:

 Most of the intrusive rocks and some of the sedimentary host rocks have experienced 

variable degrees of metasomatic hydrothermal alteration followed by lower temperature 

supergene alteration (Allegro, 1984, p. 4). Allegro (1984) described four types of hydrothermal Alteration: 1) silicification, as partial to complete replacement of the host 

rock by a dense network of quartz veinlets generally localized along contacts between the 

intrusive and sedimentary rocks; 2) sericitization, as fine- to medium-grained white mica 

in selvages along quartz veins, as anastomosing sericite-opaque mineral veinlets, and as 

patchy to massive sericitic replacement of feldspar, ferromagnesium minerals and quartz; 

3) deposition of trigonal nets of needle-like rutile often associated with secondary quartz 

and minor feldspar; and 4) epidote ± sericite as a replacement of calcic plagioclase and 

ferromagnesian minerals resulting in massive aggregates, pseudomorphs, veins, and vug 

fillings of epidote commonly associated with sericite, opaque minerals, and quartz. 

Age of mineralization:

 Felsic intrusive rocks throughout the Livengood Quadrangle, similar to those at the 

mineralized contact zone of the Old Smoky prospect, have been potassium-argon dated at 

58.0 to 88.8 m.y. (Turner and others, 1975).

Geologic description:

 In 1917, Hudson found evenly distributed small specks and grains of cinnabar in highly 

altered granitic rock at what is now commonly called the Hudson prospect (Malone, 

1962). Some of this material was reported to have run 20 to 30 pounds of mercury per 

ton (Malone, 1962). Mertie (1918, p. 274) reported that a small landslide exposed muchweathered granitic rock from which cinnabar was panned. In the main tunnel of the Hudson mine, the highly altered granitic rock is heavily impregnated with cinnabar (Reed, 

1931). The cinnabar is evenly disseminated all through the rock in small red specks and 

grains. Reed (1931) reported that the rock was so altered that it resembled talc or soft, 

white, impure sandstone. The alteration and mineralization continues back in the Hudson 

mine tunnel as far as the winze, and from there on in, the cinnabar becomes rapidly leaner 

and the country rock becomes harder and darker (Reed, 1931, p. 3). The decomposed 

quartz feldspar porphyry contains crushed white feldspar phenocrysts in a light gray to 

white ground mass of quartz, talc and clay minerals. Many iron-stained streaks in the 

porphyry are caused by oxidation of arsenopyrite-bearing quartz veins, which also carry 

some gold (Joesting, 1942; ATDM Pamph. 1, p. 2). 

 The Sunshine no. 2 prospect is a few hundred feet above the Hudson prospect. It consists of a northwest-trending, crumbly, auriferous dike with internal limonite veinlets in

Production notes:

 The owner attempted to mill the ore as if it were gold-bearing quartz and thus lost much 

of the cinnabar. The ore was ground and fed into sluice boxes in an attempt to recover 

the cinnabar. Much of the cinnabar was probably so finely ground that the sluice boxes 

were ineffective in trapping the ore (Reed, 1931, p. 3).

Geologic description:

 Gold has been found in in the lower 3 feet of gravel and on bedrock (Overbeck, 1920, p. 

181; Mertie, 1918). Bedrock is mainly chert but there is some granite at the mouth of the 

second tributary above Livengood Creek. Basalt porphyry is the bedrock at the head of 

the creek; there is limestone and argillite near the mouth (Mertie, 1918). 

 Bench gravels were mined east of the creek in 1918, to a depth of 25 to 100 feet, above 

a pay streak of 40 to 60 feet wide (Overbeck, 1920, p. 181). Concentrates of these gravels 

contain magnetite, limonite, hematite, chromite and pyromorphite. Joesting (1942, 

ATDM Pamph. 1) reported that the chromite and chrome spinel in placers was probably 

derived from serpentine in Middle Devonian basic volcanic rocks. Mining occurred in 

1916, 1922, 1924, 1926, 1928-1939, 1967-1968 (Cobb, 1976; OFR 76-633, p. 9).

Gangue minerals: 

Geologic description:

 Placer mining was reported in 1918, 1934, and 1939. At the lower placer, some flakey 

gold was obtained just above bedrock. About 1,500 feet upstream, some fine gold is present in angular wash almost at the surface (Mertie, 1918). Minerals in samples from old 

placer dumps included limonite, hematite, magnetite, epidote, spinel, chromite, ilmenite, 

gold, cinnabar and cassiterite (Wedow and others, 1954). 

 The bedrock in the basin is chiefly chert and silicified Mississippian limestone. There 

is a small body of diorite on greenstone near the head of Lucky Creek which may be a 

dike between the chert and limestone (Wedow and others, 1954). One sample contained a 

mineral in the euxenite-polycrase series, rare-earth, uranium, niobates and titanates 

(Wedow and others, 1954). Chromite and chrome spinels are abundant in Lucky Gulch 

and are probably derived from serpentine in Middle Devonian basic volcanics (Joesting,

Geologic description:

 Vault Creek has been mined over most of its length, for about 4 miles. Drift mining 

took place to the east of the current position of Vault Creek, from the mouth of Treasure 

Creek, down to the Chatanika River. Several of these drift mines are marked on the Livengood A-2 quadrangle. Placer gold is found in gravels up to 200 feet deep. Near the 

mouth in the Chatanika Flats, where recent drift mining has occurred, the alluvium is over 

300 feet thick. The pay streak of early mining operations was reported to be 100 or more 

feet wide and 3 to 6 feet thick (Prindle, 1908). Most of the mining before World War II 

was drift mining. Mining occurred from 1906 to 1940, and drift mining in the Chatanika 

flats was reported as recently as 1994 (Cobb, 1976; OFR 76-633; Swainbank and others, 

1995). Gold production, including tributaries, through 1924 was worth $2,749,000 with 

gold valued at $20.67 per ounce (Smith, 1926, p. 13). There is no record of the amount of

Geologic description:

 Drift mining operations in the Chatanika flats on lower Dome Creek were active in the 

early 1900's. Most production has come from drift mines from Seatte Creek to Olnes, and 

from dredge operations that took place in the 1950's between the mouth of Moose Creek 

to Seattle Creek; these operations are described in a separate record, ARDF no. LG049. 

Most of the mining in 1912 and 1914 was reported to have come from near the mouth in 

the Chatanika flats, however, production figures generally include the drift mines that 

were producing south of the town of Olnes (Eakin, 1915; Ellsworth and Davenport, 

1913). The depth to bedrock for all drift mining along the creek has been described as 

from 30 to 200 feet (Prindle, 1908; Prindle and Katz, 1913). Most likely, the depth to 

bedrock in the Chatanika flats is closer to 200 feet. The bedrock surface is uneven, and 

the pay streak was 130 to 165 feet wide within the lower 2 to 3 feet of gravel and upper 2 

to 3 feet of bedrock (Prindle, 1908).

Geologic description:

 This site consists of a fracture or shear zone that has been traced for 600-700 feet; it is 3 

to 5 feet wide and contains shoots and kidneys of stibnite as much as 4 feet across 

(Brooks, 1916; B 649). In places the fracture zone appears to have little ore in it and in 

others the stibnite occupies the entire zone. Between the shoots, quartz and mineralized 

schists contain small kidneys of ore. The stibnite forms finely granular and fibrous aggregates and shows only a thin film of oxidation products. Fine grains of vitreous quartz occur in the masses of stibnite. Some fractured quartz is cemented by stibnite. Some gold 

and argentiferous galena are also present. The shear zone is in part bounded by smooth 

walls and in part by zones of fractured schist. Mica schist country rock strikes N 80 E, 

and dips 80 S. One sample contained 46.53% Sb and ore samples averaged 0.75 ounces 

of gold and a trace to 1.96 ounces of silver per ton (Joesting, 1942, ATDM Pamph. 1;

 This site is a mineralized shatter zone in schist that is cut by granitic dikes. The lode 

consisits of quartz and sulfides and their oxidation products. Kidneys of stibnite, some 

coarsely columnar and some finely granular, are more abundant near the footwall than the 

hanging wall (Brooks, 1916; B 649). Some of the ore is very rich in gold; production occured from 1910 to 1912 (Brooks, 1911; Brooks, 1912). A shaft, a little more than 300 

feet deep was sunk in a vein that dips from 70 degrees at the surface to 45 degrees at the 

bottom of the shaft, and is as much as 3.5 feet wide (Smith, 1913; B 525). Granitic rock 

was encountered 50 feet from the shaft in a crosscut into the hanging wall. A decomposed granite dike was encountered in a crosscut on a 300-foot level drift. Grab samples 

from probable mill ore taken in 1931 assayed 0.07 to 0.14 ounces of gold per ton (Hill, 

1933). 

 Antimony ore was mined in 1916 (Smith, 1917; BMB 153). Some stibnite was produced during World Wars I and II (Mulligan, 1974, p. 11).

Geologic description:

 Dome Creek was one of the most productive placer gold streams in the Fairbanks mining district, and by 1973, the creek had produced more than $4,000,000 in gold from both 

surface and underground workings (Cobb, 1973). Dome Creek has been mined for more 

than three miles from above Seattle Creek nearly to Olnes on the Elliot Highway. Before 

WWI, most mining was by drifting with a depth to bedrock of up to 200 feet (Prindle and 

Katz, 1913). The portion from near the mouth of Moose Creek to Seattle Creek was 

dredged from 1955 to 1959 (R.M. Chapman, 1978, unpublished U.S.G.S. memorandum). 

Surface mining has continued intermittently to the present, notably in upper Dome Creek, 

and for several miles below the Dome Creek camp site, shown on the Livengood A-2 

topographic map. The location of drift mines on lower Dome Creek in the Chatanika 

Flats is described in ARDF No. LG044. 

 Depth to uneven bedrock surface ranges from 30 to 200 feet, with a paystreak of 130 to 

165 feet wide in the lower 2 to 3 feet of gravel and the upper 2 to 3 feet of bedrock 

(Prindle, 1908, p. 29). The middle part of the stream course is not productive, and auriferous gravel extends into the Chatanika Flats (Prindle and Katz, 1913). Concentrates 

contained gold, scheelite, and a little cassiterite (Cobb, 1976; OFR 76-633, p. 51). 

 Production, including that from tributaries, from 1903 through 1920 was about 394,245 

ounces (Cobb, 1976, p. 51). U.S.S.R. & M. Dredge no. 5 moved to Dome Creek in winter of 1954 to 1955, and worked there from 1955 to 1959 (R.M. Chapman, 1978, unLG049

pulished U.S.G.S. memorandum). During winter and early spring 1989, about 14,000 cubic yards were brought to the surface in a small scale undergound drift mine operation below the lower limit of the former U.S.S.R.& M. operations. Gravel sluiced during the 

summer of 1989 averaged 0.04 ounces of gold per cubic yard (Bundtzen and others, 1990, 

p. 35). In 1991, this same operation continued to rework old drifts and removed side pay 

left by the early 20th century hand miners (Bundtzen and others, 1992). Current sluicing 

is taking place above the dredge tailings (J. Schaefer, 1999, field observation).

Workings/exploration:

 Surface and underground workings have produced gold. U.S.S.R. & M. Dredge no. 5 

moved to Dome Creek in winter of 1954 to 1955, and worked there from 1955 to 1959 

(Chapman, 1978, U.S.G.S. memorandum). A small scale undergound drift mine by Roberts Mining was started in 1989 below the lower limit of former U.S.S.R. & M. dredging 

activities (Bundtzen and others, 1990, p. 35) and continued until 1993 (Bundtzen and others, 1994, p. 29). In 1991, Robert's Mining mined 11,470 cubic meters (15,000 cubic 

yards) of rich placer pay at the drift mine, reworking old drifts and removing side pay left 

by the early 20th century hand miners (Bundtzen and others, 1992). RCL Mining worked 

both an underground drift mine and washed old drift tailings on Dome Creek, below the 

Roberts Mining operation (Swainbank and others, 1993). Current operations consist of a 

cat feeding a sluice box, above the dredge tailings (J. Schaefer, 1999, field observation). 

Production notes:

 Dome Creek was one of the most productive placer gold streams in the Fairbanks mining district, and by 1973, the creek had produced more than $4,000,000 in gold from both 

surface and underground workings (Cobb, 1973). During winter and early spring 1989, 

about 14,000 cubic yards were brought to the surface and stockpiled for summer sluicing. 

Gravel sluiced during the summer of 1989 averaged 0.04 ounces per cubic yard 

(Bundtzen and others, 1990, p. 35).

Geologic description:

 Gold is found in quartz veins in a shear zone containing stibnite, arsenopyrite, auriferous tetrahedrite, and galena. Two veins, the Wild Rose and the Soo, trend east and dip 

north. The Chief vein trends N 50 E and dips 50 NW. The veins contain free gold, some 

of which is smeared on slickenside surfaces (Smith, 1913; B 525). Gold fineness ranges 

from 823 to 843 (Smith, 1913; B 525). Much of the ore contained $50 to $60 or more per 

ton, with some of the richest running over $250 per ton (Smith, 1913; B 525). Hill (1933) 

reported that typical ore from the H-K vein shows two generations of quartz; one with a 

little gold and the second with pyrite, arsenopyrite, stibnite and free gold. 

 The Wild Rose vein contains small bunches of stibnite with a little galena, tetrahedrite, 

and copper sulfides (Chapin, 1914). Specimens of stibnite consist of columnar and fibrous masses, together with fine granular aggregates (Brooks, 1916; B 649). Specimens 

of curved and bladed crystals of stibnite contain over 60% Sb (Joesting, 1942; ATDM 

Pamph. 1). 

 The mine operated intermittently from 1910 to 1936. Total gold production from 1912 

to 1914 and from 1925 to 1931 was between $140,000 and $165,000, or about 7500 

ounces (Hill, 1933). Ebbley and Wright (1948, p. 38) reported that antimony ore had 

been produced.

Location description and accuracy:

 The True North property lies approximately 2 miles northwest of Pedro Dome. It covers approximately 11,000 acres of State of Alaska Mining claims and patented Federal 

mining claims (Masterman, 1998). The location given is the approximate center of those 

claims. The Hindenburg/Markovich mine (ARDF no. LG054) is part of the True North 

prospect.

Geologic description:

 The True North gold deposit is a structurally controlled, disseminated gold deposit located on the northwest flank of Pedro Dome. Gold was recognized on the property as 

early as 1913, but historic production was limited to stibnite ore, mined from the Hindenburg/Markovich mine (ARDF no. LG054), which is located within the current True North 

land holdings. 

 Mineralization at True North is associated with quartz-carbonate veins in a heterogeneous high-grade metamorphic package containing calcareous eclogites, particularly where 

carbonaceous schists and quartzite are prevalent (Swainbank and others, 1998, p. 8). 

Gold occurs within a northeast-trending zone, 2500 feet wide and 5000 feet long, west of 

the northeast-trending Eldorado Fault. Gold-bearing zones are typically 20 to 60 feet 

thick within gently dipping shear zones and faulted lithologic contacts (Masterman, 

1998). Gold grades within the shear zones average 0.05 to 0.10 ounces of gold per ton 

(Masterman, 1998). Ar-Ar dating of alteration associated with mineralization at Fort 

Knox, Ryan Lode, Golden Summit and True North all place the main mineralizing event 

at +/- 90 Ma (Masterman, 1998). 

 Exploration activities on the True North property from 1991 to 1997 consisted of 9,832 

top-of-bedrock soil samples, 15,621 feet of trenching, 40,133 feet of core drilling and 

LG055 
Alaska Resource Data File 

Page 115 

153,914 feet of RC drilling (Masterman, 1998). Auger soil-sampling programs occurred 

in 1998 (Szumigala and Swainbank, 1999, p. 10). There is particular interest in a 400 

foot by 1,000 foot gold-arsenic-antimony anomaly occurring southwest of the True North 

trend (Szumigala and Swainbank, 1999, p. 10). 

 As of 1997, geologic resources were calculated to be 1.3 million ounces of gold with a 

grade of 0.072 ounces of gold per ton (Swainbank and others, 1998, p. 8; Masterman, 

1998). In 1997, core drilling and 55,000 feet of reverse-circulation drilling led to the discovery of the Merlyn and Dome Creek mineralized zones (Swainbank and others, 1998, 

p.8).

Workings/exploration:

 The following history of exploration is based on an extended abstract presented by 

Steve Masterman, Newmont Exploration Limited, at the 1998 Alaska Miners Association 

Meeting. In 1990, Dick Swainbank brought the property to the attention of AMAX Gold, 

Inc. (AGI). AGI acquired the claims and conducted soil sampling, trenching, and 6,332 

feet of reverse-circulation (RC) drilling. In 1994, after drilling 14 RC holes under an exploration agreement, LaTeko acquired the property from AGI. During the summer of 

1994, LaTeko expanded the soil grid, excavated additional trenches, drilled 52,000 feet of 

RC and 2,040 feet of HQ core. In 1995, Newmont Exploration Ltd. began exploration on 

the property, after entering into a joint venture with LaTeko. Exploration activities on the 

True North property from 1991 to 1997 consisted of 9,832 top-of-bedrock soil samples, 

15,621 feet of trenching, 40,133 feet of core drilling, and 153,914 feet of RC drilling 

(Masterman, 1998). In 1998, most exploration work consisted of auger soil sampling programs (Szumigala and Swainbank, 1999, p. 10). In 1999, Kinross Gold Exploration acquired Newmont's 65% interest in the True North Venture. 

Production notes:

 

Reserves:

 As of 1997, geologic resources were calculated to be 1.3 million ounces of gold with a 

grade of 0.072 ounces of gold per ton (Swainbank and others, 1998, p. 8; Masterman, 

LG055 
Alaska Resource Data File 

Page 116 

1998). 

Additional comments:

 Metallurgical tests found that gold recoveries would probably be 85-95% for the 1.3 

million ounces of gold in the non-sulfide, coarse material from the oxide zones at the 

Hindenburg and Shepard prospects (Szumigala and Swainbank, 1999, p. 10). Deeper, 

more sulfide-rich samples from the Hindenburg and the Shepard prospects probably will 

have gold recoveries ranging from 61 to 68%.

and pelitic schist of the Fairbanks schist unit (Weber and others, 1992). Gold is mainly in 

the bench placers with some gold in the creek. Bedrock is quartz-mica schist at a depth of 

60 to 120 feet (Prindle, 1908). Concentrates contain gold, cassiterite, scheelite, and 

wolframite (Prindle and Katz, 1909; Johnson, 1910). Bench placer mining took place in 

1907-27, 1930-31, 1938-40 and drift mining has been active throughout the 1990's, especially in the lower parts of the creek (Cobb, 1976; OFR 76-633, p. 113-114; Swainbank 

and others, 1998). U.S.S.R. & M. Dredge no. 5 moved to Little Eldorado Creek in 1948 

and worked there from 1948 to 1954 (R. M. Chapman, 1978, U.S.G.S. memorandum). 

Total production as of 1924 was worth $2,414,000 (Smith, 1926), and production figures 

are not available for more recent operations. More recent drift mining in the 1990's has 

taken place in the Chatanika flats, near the mouth of Little Eldorado Creek (ARDF no. 

LG045).

Geologic description:

 The Silver Fox mine consists of a series of quartz veins within a Cretaceous tonalite intrusive, surrounded by quartz muscovite schist, quartzite and chlorite quartzose schist. 

Quartz veins in tonalite contain scattered, flattened, small pods of molybdenite (Mowatt, 

1974). Pyrite and chalcopyrite are smeared on slickensided fracture surfaces that offset 

these molybdenite-quartz veins. Across the fault zone is an area of fissure veins carrying 

pyrite, argentiferous galena, and sphalerite. Channel samples of iron-stained quartz veins 

containing argentiferous galena, jamesonite, alteration products, and some gold contained 

2-5 % Pb, 2.9-8.8 ounces of silver per ton and 0.06-0.36 ounces of gold per ton (Berg and 

Cobb, 1967). Forbes and others (1968) reported fissure veins in quartz diorite consisting 

of argentiferous galena, sphalerite, tetrahedrite and pyrite, with subordinate gold values. 

Trenching exposed a roof zone of quartz monzonite plutons, roof pendants of silicified 

schist, and auriferous quartz stringers and veins. A 30-foot-wide altered zone includes 

both silicified schist and silicified quartz monzonite. Stibnite lenses occur along the 

hanging wall of the south vein, and a sample from an altered rind of one lens contained 

23.0 ppm Au (Forbers and others, 1968). Chapman and Foster (1969) described this site 

as having NW-trending fissure veins in quartz diorite with scheelite and powellite limited 

to thin calcite veinlets and coatings along joints and fracture planes. 

 In 1974, workings consisted of a 375 foot adit with a working face at the end of a 50 

LG062

foot long drift and another face about 85 feet below the ground surface (Mowatt, 1974). 

In the late 1970's (probably 1978), the 50 foot long drift was extended approximately another 100 feet , and six 55-gallon barrels of silver ore were shipped (D. Wietchy, oral 

commun., 1999). 

 In 1973, the mine was operated as a tourist attraction. Currently the mine is owned by 

the University of Alaska and is used as a teaching mine.

Geologic description:

 Pedro Creek was a major placer gold producer in the Fairbanks mining district, with 

placered ground extending almost 4.5 miles, from the mouth of Twin Creek to the confluence with Gilmore Creek. Placer gold on Pedro Creek is both very fine and coarse and 

was found in the bottom 2 to 7 feet of gravel and the top 1 to 5 feet of bedrock (Prindle, 

1904; Brooks, 1905). The depth to quartzite schist bedrock is 9 to 35 feet (Prindle, 

1904; Prindle and Katz, 1909). Heavy minerals found with the gold are magnetite, garnet, rutile and pyrite (Prindle, 1905). The paystreak is from 4 to over 200 feet wide 

(Brooks, 1905). Mining was by drifting, open cuts, and dredges (Cobb, 1976; OFR 76-

633). U.S.S.R. & M. Co. dredge no. 4 was built on Pedro Creek in 1939, and the dredge 

worked there from 1939 to 1942, and from 1952 to 1958 (R.M. Chapman, U.S.G.S. unpublished memorandum, 1978). Recent mining has been reported near the mouth of 

Steamboat Creek (D. Grybeck, oral commun., 1999). The value of gold produced from 

1903 to 1910 was $1,250,000 (the gold was then valued at $17.68 per ounce) (Prindle and 

Katz, 1913). More recent production figures are not available.

Workings/exploration:

 In 1958, Pete Smith, a local placer miner, found some pieces of galena-bearing float in 

the valley of Steamboat Creek (Saunders, 1963; ATDM PE 49-15). He attempted to trace 

the float to its bedrock source by hand-trenching and trenching with a bulldozer. The 

Alaska Department of Mines investigated the area in the early 1960's by bulldozer trenching, hand-digging pits and auger hole drilling for geochemical sampling. By 1968, the 

owners of the lode prospect were conducting rotary drilling and intended to drill about 

450 feet (Vance, 1968). 

Production notes:

 In 1963, it was reported that the owners of the prospect planned to mine and ship ore 

from an exposed vein. It is not known whether or not mining took place (Saunder, 1963; 

ATDM PE 49-15).

Ore minerals: Arsenopyrite, gold 

Gangue minerals: 

Geologic description:

 Hill (1933) visited the site and the following geologic description is a summary of his 

observations. Extensive exposures of mineralized quartz diorite and schist occur in a hydraulic cut on the Zimmerman property. Near the southwest or lower end of the cut, a 

fault zone strikes east and dips 85 N. The fault zone consists of 11 feet of blue clay 

gouge that contains a large amount of fragmental quartz and silicified schist. Some of the 

fragments contain arsenopyrite and have a peculiar greenish-yellow stain. A few samples 

from a 3-foot zone of silicified mineralized schist contained as much as 0.08 ounces of 

gold per ton. 

 Northeast of the gouge, the rock is quartz diorite. For seven feet above the fault, the 

diorite is badly crushed, but farther to the northeast, it is less altered, breaks in blocky 

forms, and is cut by several minor fault fractures that strike from west to N 60 W. Southwest of the main fault, the rock is highly silicified schist with many quartz veinlets and 

everywhere contains a small amount of finely disseminated arsenopyrite. The rock is bluish gray, hard, and heavier than the nomal quartz-mica schist. For at least 70 feet south of 

the main fault, this rock is broken and crushed, and there are several well-defined slip 

planes that vary in strike from N 70 W to west and dip north, all roughly parallel to the 

main fault. 

 The samples of the altered quartz diorite north of the fault contained neither gold nor 

silver. The silicified mineralized schist south of the fault carried only a trace of precious

metals except for a few samples from a 3-foot zone that contained as much as 0.08 ounces 

of gold per ton. The gold-bearing samples contained notable sulfides (Hill, 1933, p. 118-

Geologic description:

 Gold is found in an east-west-striking, vertical fracture zone in coarse porphyritic granite that has been cut by quartz veins. The quartz veins are broken by iron-stained joints 

whose surfaces are mineralized and carry gold (Brooks, 1916; B 642; Brooks, 1918). The 

mineralized zone has been traced for 900 feet on the surface (Brooks, 1918). The fracture 

zone becomes barren where it crosses the contact from granite into the schist (Brooks, 

1916; B 642). Pyrite, arsenopyrite, and galena are present (Brooks, 1916; B 642). 

 This deposit has been developed by two tunnels. In the upper tunnel, quartz veinlets are 

in a zone 8-10 inches wide in porphyritic granite. This zone is vertical and strikes N 70 E 

(Hill, 1933). About two-thirds of the gold is in sulfide minerals, and assays show 0.19 to 

1.84 ounces of gold per ton (Cobb, 1976; OFR 76-633, p. 103).

Geologic description:

 This prospect consists of gold-bearing quartz veins in heavily silicified schist. Hill 

(1933, p. 116-117) visited the area in 1931 and described the prospect: A shallow shaft 

was driven on a vein trending N 84 W and dipping 85 S, which yielded ore valued at 

$5,000. As exposed in the tunnel, this vein is from 1 to 4 inches wide and consists of 

white quartz frozen to a dark, heavily silicified schist. Some of the quartz carries minor 

sulfides, but in general it has no visible metallic mineralization. This vein cuts across a 

lenticular mass of quartz lying parallel to the schistosity, which dips 15 SE. A 30-inch 

aplite dike that strikes north and dips 15 E is also cut by this vein. In open cuts, the vein 

was observed to be 3 to 6 inches wide and in places lies along the contact of schist and 

porphyritic granite. About 140 feet north of this vein, another 5-inch quartz vein in schist 

was said to have produced a ton of $35 ore (1.69 ounces of gold per ton). 

 When Hill (1933) visited the site in 1931, the Big Lead vein was exposed along an old 

wagon road on the east side of Skoogy Gulch just south of a cabin. Several feet of tunnels were driven on this vein and an engineer that visited the site estimated that the whole 

ore body exposed in these tunnels would average about $4 per ton (0.19 ounces of gold 

per ton). The tunnels were caved by 1931, but the material on the dump consisited of

heavily iron-stained mineralized schist and quartzite. One dump site contained boulders 

dominated by arsenopyrite and stibnite. There is evidence of silicification and mineralization over a width of 75.5 feet. The mineralized zone shows an alternation of schist, altered dike rocks, quartz veinlets, and faults. A sample of granular, highly altered, brickred dike rock containing irregular veinlets and bunches of manganese-oxide; it assayed

pyrite which are oxidized to iron-oxide and lead-oxide. The adit was caved and inaccessible by 1931 (Hill, 1933).

Geologic description:

 By 1912, William Jackson had staked the Silver King claim and exposed a flat-lying 

bed of massive sulfides (Times Publishing Company, 1912). This occurrence contained 

arsenopyrite, stibnite, galena, pyrite and at least one lead sulfosalt; it was conformable to 

the surrounding schists (Smith, 1913; B 525). The sulfide bed was one foot thick and was 

largely oxidized to scorodite and antimony oxides with borders of quartz and sulfide 

stringers in the surrounding schist (Chapin, 1914). By 1916, the prospect was known as 

the Silver King or Little Jim prospect and consisted of two open cuts approximately 250 

feet apart, both of which hosted a flat-lying sulfide horizon in the metamorphic country 

rocks (Mertie, 1918). The southeastern open cut exposed 12 inches of massive sulfides, 

trending east-west and dipping 25 S. A shaft was sunk about 25 feet south of the open cut 

to intersect the horizon. The other open cut, 250 feet to the northeast exposed a 4-inchthick sulfide-bearing seam with euhedral quartz crystals in its matrix. This occurrence 

strikes N 45 E and dips at a low angle to the southeast. The mica schist country rock is 

heavily stained with iron-oxides for 6 to 7 inches on either side of the sulfide horizon and 

assays $6 to $7 per ton in gold (0.29 to 0.33 ounces of gold per ton). The sulfide horizons 

on the Wackwitz prospect contained extremely high silver contents relative to gold 

(Mertie, 1918). 

 In the early 1950's, the prospect was known as the 'Polaris' lead-silver prospect when 34 

tons of hand-picked lead-silver ore was produced from two open cuts, approximately 

1300 feet apart (Saunders, 1954). The mineral deposit was said to strike about N 80 W 

LG090 
Alaska Resource Data File 

Page 186 

and dip 20 S. The vein-filling was mostly sulfides, mainly galena and stibnite. The vein 

had an average thickness of about 8 inches. Smelter returns of sorted ore contained 0.10 

to 0.20 ounces of gold per ton, 16.97 to 98.95 ounces of silver per ton and 23.35% to 

47.7% lead (Saunders, 1954, p. 5). 

 Metz and Robinson (1980) examined the Wackwitz prospect and noted the mineralization consisted of a one-meter-thick massive sulfide horizon in quartz muscovite schist 

striking N 60 E and dipping flatly to the southeast. Polished sections of the mineralization contained stibnite, jamesonite, galena, sphalerite, arsenopyrite and pyrite which occur 

in discrete bands. By volume stibnite constitutes 90% of the lens, sphalerite 5%, galena 

2% and jamesonite, arsenopyrite and pyrite 1% each. 

 In 1983, a 100-pound metallurgical sample was collected from a 12-inch thick horizon 

of massive sulfide on the Wackwitz prospect. This sample assayed 3 to 5 ounces of silver 

per ton, 0.08 ounces of gold per ton, 5 to 10% arsenic, 1 to 10% antimony and greater 

than 10% lead (Wu-Ming, 1983). Oxide phases present included senarmontite, scorodite, 

cervantite and bindhemite, while metallic phase minerals included arsenopyrite, pyrite, 

jamesonite, boulangerite, tetrahedrite, galena, stibnite and sphalerite. Gold was associated as free inclusions in arsenopyrite; silver was present in tetrahedrite. Crushing and 

grinding tests indicated precious metals were most abundant in the minus-265-mesh fraction. Thiourea leaching of the Wackwitz ores indicated optimum silver recovery of only 

40% on a 24 hour leach. Gold recovery by thiourea leaching was not investigated (WuMing, 1983).

Geologic description:

 Several lode discoveries had been made on the prospect by 1912 including a goldsilver-base metal occurrence on the Your Jim, Big Jim and Our Jim claims which is described here as the Jackson prospect. Development on the Your Jim claims in 1912 consisted of a 60-foot shaft and 30 feet of drifting on the 30-foot level. Mineralization consists of a 26-inch-wide, northeast-striking, 45 degree southeast-dipping shear zone containing 12 inches of white quartz and 8 inches of gouge. Pyrite with gold and silver values is the primary metallic mineral. Two assays conducted in April, 1912 returned values 

of 5 ounces per ton in gold and 2 ounces per ton in silver, and 19.1 ounces per ton in gold 

and 9 ounces per ton in silver (Times Publishing Company, 1912). In late 1912, work 

was being planned to deepen the shaft to 100 feet and begin development drifting at that 

level. 

 By 1913, an adit had been driven on the Your Jim and Our Jim claims for a length of 

428 feet in quartzite schist (Chapin, 1914). At the 70-foot station, the adit intersected a 

thin quartz stringer containing gold and silver of unspecified grade. A series of east-west 

trending faults which cut the adit also reportedly contained considerable gold. A fault 

which cuts the adit at the 300-foot station contains abundant sulfides but no free gold 

(Chapin, 1914). The shaft previously sunk to a depth of 60 feet was abandoned and a second shaft 25 feet south of that point was sunk prior to 1916. This shaft follows a N 45 E, 

45 SE shear zone containing galena, arsenopyrite and minor pyrite (Mertie, 1918). By 

LG091 
Alaska Resource Data File 

Page 189 

1916, the adit on the Jackson prospect had been extended to 516 feet and crossed a series 

of mineralized shear zones. At 70 feet, the adit intersected a N 45 E, 65 NE shear zone. 

At 123 feet, the adit intersected a N 75 W, 75 SW shear zone. At 200 feet, the adit intersected a N 75 W, 65 SW shear zone. At 300 feet, the adit intersected a N 75 W, steeply 

southwest-dipping shear zone which exposes a 4-inch-wide crushed quartz stringer containing gold and sulfides. At 380 feet, the adit intersected a N 40 W striking, 45 NE shear 

zone which exposed an 18 inch wide gouge zone containing silver mineralization (Mertie, 

1916). 

 The prospect was examined in 1931 by Hill (1933) but had been abandoned for many 

years at that time. The adit and shafts were caved and only a minor amount of mineralization was exposed on the dumps. This dump material contained pyrite, galena, arsenopyrite, stibnite, jamesonite and free gold along with an unspecified silver-bearing mineral. 

The Jackson prospect was examined as a possible source of antimony in 1942 but no additional exploration was conducted due to insufficient tonnage potential (Killeen and 

Mertie, 1951).

(0.3 ounces of gold per ton) and $4.50 per ton in silver (9 ounces of silver per ton). Smith 

(1913, B 525) was unable to determine the strike and dip of the prospect due to frost action on surface exposures. By 1916, the shaft was 14 feet deep with a short drift at the 

bottom on a 8-inch-wide, N 55 E, 15 SE shear zone. Mineralization consisted of stibnite 

with gold and silver credits, arsenopyrite and silver-bearing tetrahedrite. The shear zone 

was hosted in an iron oxide stained schist cut by numerous quartz stringers (Mertie, 

1918). The Cheyenne prospect was examined as a possible source of antimony in 1942 

but no additional exploration was conducted due to insufficient tonnage (Killeen and

Geologic description:

 By 1909, a 40 foot shaft had been sunk on the prospect and a northeast striking, steeply 

southeast dipping quartz-bearing shear zone was exposed. The higher grade portion of 

the shear was 2 to 16 inches wide and contained gold, stibnite, arsenopyrite, pyrite and 

minor sphalerite (Prindle, 1910). The schist host rock is strongly brecciated and cemented by quartz. By 1912, the shaft had been sunk to a depth of 60 feet with short drifts 

at the 60-foot level (Smith, 1913; B 525). The shear is hosted in part by mafic metavolcanic rocks and exhibits considerable offset by faulting. The shear dips steeply to the 

south at the surface but flattens to 45 degrees at depth. Ten tons of ore from this prospect 

were milled in Fairbanks and contained $38 per ton in gold (1.8 ounces of gold per ton). 

Chapin (1914) reported that in 1913 the drifts at the 60-foot level were 30 feet and 70 feet 

long to the east and west, respectively. An adit was being driven from the Willow Creek 

basin to allow exploration and development to proceed. A minor amount of exploration 

was completed on the prospect in 1914 (Eakin, 1915). A small amount of production was 

recorded from the prospect in 1917 however no tonnage or grade information is available 

(Martin, 1919). The prospect was idle until 1924 when it was re-opened, however, it was 

abandoned shortly afterwards and was idle when visited in 1931 (Hill, 1933).

Geologic description:

 The prospect consists of a sericitized granite porphyry dike which cuts a stibnitebearing schist. The stibnite occurs as pods and veinlets in the schist and as a surface coating on the dike contact (Prindle, 1910). Specimens of ore from this deposit are made up 

of a granular aggregate of stibnite (Brooks, 1916, p. 33; B 649). The aggregates are 

highly weathered, and a little pyrite occurs with the stibnite. There are also some vitreous 

quartz grains buried in the stibnite; some of these grains showed crystal terminations 

(Brooks, 1916, p. 33; B 649). 

 The stibnite contains less that $1 per ton in gold (0.05 ounces of gold per ton) but the 

grade of the granite porphyry is unknown. The prospect was idle in 1916 and was noted 

to be associated with a horizontal structure which may have been parallel to foliation 

(Brooks, 1916; B 649). The Mother Lode prospect was examined as a possible source of 

antimony in 1942 but no additional exploration was conducted due to insufficient tonnage 

potential (Killeen and Mertie, 1951).

Geologic description:

 The Robinson mine contains several quartz veins that contain free gold, stibnite, pyrite, 

and arsenopyrite. The veins cut gray calcareous quartzites with stockwork quartz. Pyrite 

and arsenopyrite are the two most abundant disseminated minerals in the wall rocks 

(Freeman, 1992). The initial 1-foot-wide shear zone, exposed in a 180 foot adit, has a 

strike of N 10 E with a steep dip to the west. A second shear was discovered near the 

shaft house. This shear strikes N 70 W, dips vertically, and is 8 inches wide (Chapin, 

1914). Another shear zone was intersected west of the 50-foot level of an inclined shaft. 

This high-grade quartz-rich vein is 16 to 18 inches thick and strikes N 20 E and dips 60 

NW. A second shaft, known as the Boyd shaft, was located 75 feet northwest of the 

Robinson shaft and had been sunk to a depth of 30 feet in 1916. The shear exposed in the 

Boyd shaft contains abundant arsenopyrite; it is oriented N 80 W, 35 SW. 

 Dump samples collected from the Robinson prospect in 1986 contained from trace to 

4.182 ounces of gold per ton, greater than 1,000 ppm arsenic, minor antimony, and trace 

levels of silver (Freeman and others, 1986). 

 Accurate production records for the Robinson mine are not available, however, based 

on mine maps provided by Charles Lazeration, production is estimated at approximately 

5,000 tons of ore (Freeman, 1992).

Workings/exploration:

 By 1912, a 180 foot adit had been driven on a 1-foot-wide, quartz-rich shear zone 

(Smith, 1913; B 525). By 1913, the prospect was being explored by L. Goyett through a 

50-foot inclined shaft on a 4-foot-wide shear zone (Chapin, 1914). At the 50-foot level, 

the shaft becomes vertical for 25 feet, at which point a 20-foot cross-cut was driven to intersect an 8-foot-wide shear zone. A second shaft, known as the Boyd shaft, was located 

75 feet northwest of the Robinson shaft and had been sunk to a depth of 30 feet by 1916 

(Mertie, 1918). By 1917, the Robinson prospect was known as the Heilig and Creighton 

mine, and was equipped with a Little Giant mill (Martin, 1919). No new development 

work had been conducted on the prospect in 1917. Work was continued in 1918 but no 

production was reported (Martin, 1920). In 1934, the Robinson shaft and Boyd and Shaw 

shaft were flooded and the open cut between the two shafts filled with debris and water 

(Spencer and O'Neill, 1934). In 1934, Fred C. Robinson was living on the Robinson 

prospect but no work had been done on the prospect for several years (Spencer and O'-

Neill, 1934). In 1938, Fred Robinson cleaned out the Robinson shaft and repaired the 

mill. The Robinson prospect was examined as a possible source of antimony in 1942, but 

no additional exploration was recommended due to insufficient potential for significant

and Charles Lazeration. Ore was milled at the Cleary Hill mill. Mr. Lazeration, presently 

residing in Fairbanks, has provided two mine maps of the Robinson mine which show 

workings on the 60-, 100- and 200-foot levels from a shaft driven to a depth of approximately 210 feet (Fairbanks Exploration Inc., unpublished report, 1986). Drifts on the 

200-foot level had been driven 470 feet along the shear to the northeast and 250 feet to 

the southwest. A ventilation shaft at the 190 foot station of the southwest drift connects 

with the surface. At the 470-foot station of the northeast drift on the 200-foot level, a 

stope had been worked to the 100-foot level and nine ore draw points had been installed 

and were ready for use. The 100-foot level was driven 470 feet to the northeast and 190 

feet to the southwest where a ventilation shaft connected it with the surface. The 100-foot 

level was mined out over its entire 470-foot length on the northeastern side of the 100-

foot level and over its entire 190-foot length on the southwestern side of the shaft. The 

60-foot level was mined out over a 90-foot length from the raise to the ventilation shaft 

connecting the three levels on the southwestern side of the shaft. The Robinson shaft currently is flooded and inaccessible (Freeman, 1992).

Production notes:

 By 1912, a 180-foot adit had been driven on a 1-foot-wide quartz-rich shear zone 

(Smith, 1913; B 525). Two tons of ore from this adit were custom milled in Fairbanks 

and produced a large amount of sulfide concentrate and an unspecified amount of gold. 

By 1916, the prospect was known as the Mohawk prospect and produced 46 tons of ore 

over a four month period. Work was continued in 1918 but no production was indicated 

(Martin, 1920). Active mining was being conducted on the Robinson prospect in 1950; 

the ore was milled at the Cleary Hill mill (Saarela, 1951). 

 Accurate production records for the Robinson mine are not available, however, based 

on mine maps provided by Charles Lazeration; the production is estimated at approximately 5,000 tons of ore (Freeman, 1992).

Additional comments:

 The Robinson mine was previously known as the Creighton mine but was sometimes 

called the Franklin mine (the owner at one time was Duane Franklin).

Geologic description:

 The quartz mica schist which makes up the country rock at this prospect trends N 60 E 

and dips 15 to 20 SE. Diorite of the Pedro Dome intrusive crops out a short distance 

south of the adit. The prospect was accessed by a 145-foot-long adit on a shear zone 

striking N 40 E and dipping 70 NW. The shear zone ranges from 12 to 40 inches wide 

and averages 30 inches. It is composed of crushed and brecciated white quartz in the 

hanging wall and more massive white quartz in the footwall. Samples collected from the 

margins of the shear contained from $0.38 to $3.26 per ton in gold (0.02 to 0.15 ounces of 

gold per ton) but do not represent the higher grade portion of the shear which was unsafe 

to sample (Hill, 1933). Approximately 1,300 tons of ore was extracted from the adit 

which was estimated to contain $5 per ton in gold (0.24 ounces of gold per ton). A second tunnel, known as the Dome View #2, was driven on a shear about 1,000 feet southwest of the Dome View #1 adit. The Dome View #2 was thought to be the same shear as 

exposed in the Dome View #1 adit; however, the Dome View #2 shear dips in the opposite direction and probably represents a different shear zone. 

 The prospect was mapped and sampled in 1933 by Spencer and O'Neill (1934) who reported that a shaft sunk near the Dome View #2 adit had exposed arsenopyrite- and pyrite-rich quartz containing a little free milling gold. Spencer and O'Neill (1934) attributed 

the formation of the Dome View prospect to the Pedro Dome intrusive body. Scorodite 

and iron oxide are common in brecciated quartz from the Dome View prospect. Two

samples collected at 18 and 30 feet from the Dome View #1 portal averaged 0.10 and 

0.12 ounces of gold per ton, over 18 and 24 inches, respectively. A grab sample of 

quartz-rich material from this adit's dump returned 0.32 ounces of gold per ton A dump 

sample from the Dome View #2 shaft contained 1.94 ounces of gold per ton from material 

containing 30 to 40% sulfides. The shear at the Dome View #2 shaft trends N 85 E and 

dips 70 SW. Two samples collected from the dump of the Dome View #2 shaft in 1969 

contained greater than 150 ppm gold. 

 The prospect was examined in 1986 by Fairbanks Exploration Inc. (Fairbanks Exploration Inc., unpublished report, 1986). Exploration pits and at least two caved adits on the 

prospect expose bedrock similar to those at the Newsboy mine; however felsic schist apparently constitutes a smaller portion of the rock section in the vicinity of the Dome View 

prospect. The predominant alteration present in samples collected on the prospect was 

stockwork silicification accompanied by hematite after pyrite, and scorodite after arsenopyrite (Fairbanks Exploration Inc., unpublished report, 1986). Despite the lack of intense 

alteration, gold values ranged up to 6100 ppb and were accompanied by anomalous silver, 

antimony and arsenic. No work has been conducted on this prospect since 1986.

Geologic description:

 Brooks (1911) reported that by 1910 a 140 foot adit had been driven on a 3-foot-wide 

quartz-rich shear zone on the prospect. The shear reportedly contained elevated gold values. In addition, a 38-foot-deep shaft had been sunk on a 5-foot-wide quartz-rich shear 

zone in the same area and may be part of the same shear zone. By 1914, the adit had been 

extended to 250 feet. The mineralization was hosted in a N 60 E trending, steeply south 

dipping shear zone which contained visible gold in quartz and in the schist host rocks. 

Strike-slip motion of undetermined magnitude was noted along the Hidden Treasure shear 

zone (Brooks, 1914). Although ore was milled from these workings, no production figures are available due to loss of the amalgam from the custom mill (Brooks, 1914). 

 There are no references to the Hidden Treasure prospect from 1914 through 1930. The 

Hidden Treasure prospect was examined in 1931 but the adit had caved and the dumps 

were overgrown with vegetation (Hill, 1933). Samples collected by Spencer and O'Neill 

(1934) from shaft dumps on the prospect contained only a trace of gold. In 1938, the 

prospect was owned by Fred C. Robinson and was leased in the fall of 1938 to Paul Bittner, Normal Crooks, and Ed Saponch (Reed, 1939). In November, 1938 the lessees excavated a road to the prospect from the Newsboy mine, removed the ice from the adit and 

opened a raise in the old workings. Samples collected in the raise averaged $6 per ton in 

gold (0.17 ounces of gold per ton). After three weeks, the work was abandoned and the

lease terminated. 

 In 1985, Dwayne Savage leased the prospect and reported visible gold in quartz samples 

from the Hidden Treasure dump (D. Savage, oral commun., 1985). Samples collected 

from the prospect contained anomalous arsenic but only trace gold, silver and antimony 

(Resource Associates of Alaska, unpublished report, 1985).

Geologic description:

 The Newsboy mine as one of the major producers of the Cleary Hill area. It began production in 1911 and continued intermittently until World War II. 

 The Newsboy mine is hosted in dark green, massive to tightly foliated chlorite-actinolite 

schist of basaltic origin. The country rocks trend N 60-80 E and dip 0 to 30 NW 

(Robinson and others, 1990). Mine dumps also indicate a significant proportion of 

quartz-biotite-mica schist and quartz-sericite schist with abundant white to granular 

quartz stockwork and pervasive flood silica (Freeman, 1992). Movement on the main 

Newsboy structure appears to be of multiple-age, strike-slip character. However, dip-slip 

displacement is probably present, but difficult to discern due to the intensity and complexity of the movements (Freeman, 1992). The Newsboy shear zone is situated on the 

northwest limb of the Cleary antiform and is cut by a series of poorly understood, eastwest trending faults which dip predominantly to the north at angles ranging from 57 to 80 

degrees. These structures truncate the mineralization and despite several hundred feet of 

drilling and exploratory drifting, the continuation of the shear zone could not be located 

(Freeman, 1992). 

 Mineralization at the Newsboy mine consists primarily of native gold plus arsenopyrite, 

some of it auriferous, with lesser amounts of stibnite, chalcopyrite, sphalerite and ubiquitous pyrite (Fairbanks Exploration Inc., unpublished report, 1986). Ore in the Newsboy 

LG100 
Alaska Resource Data File 

Page 211 

mine is similar to that at the nearby Tolovana mine, about one mile east and 650 feet 

lower than the Newsboy shaft (Brooks, 1913). White quartz, shear zones and stockworks 

range from 2 to 14 feet wide and average about 4 to 5 feet wide in the upper 200 feet of 

workings (Hill, 1933; Stewart, 1931). 

 Samples collected in 1986 from the Newsboy mine dumps contain high arsenic and 

gold contents coupled with erratic but generally low antimony and silver contents 

(Fairbanks Exploration Inc., unpublished report, 1986). Gold values range from 260 ppb 

to 4.180 troy ounces per ton. Samples taken from mill sulfide concentrates and stamp 

tailings near the old Newsboy mill contain much gold with abundant arsenopyrite and pyrite. Sulfide-rich mill concentrates varied from 1.433 to 3.377 ounces of gold per ton. 

Stamp sand tailings returned grades ranging from 0.087 to 0.163 ounces of gold per ton 

(Fairbanks Exploration Inc., unpublished report, 1986). A significant amount of gold 

(810 to 5700 ppb) was detected in quartz-sericite schist derived from rhyolite tuff and exhalite (Fairbanks Exploration Inc., unpublished report, 1986).

Workings/exploration:

 The Newsboy mine was first staked June 25, 1909 (Times Publishing Company, 1912). 

The Newsboy shear zone was traced for several hundred feet on the surface and additional 

claims were staked. In October, 1911, a 5-stamp Joshua Hendy Mill was erected (Brooks, 

1912; Smith, 1913, B 525). The mill operated for only a few months due to lack of water. Brooks (1912) indicated that by mid-1911 the Newsboy Mine shaft had reached the 

200-foot level and working drifts had been driven on the 60-foot and 115-foot levels. By 

the end of 1911 the bottom of the shaft was at the 315-foot level and drifting was being 

conducted on a 4-foot-wide shear zone on the 215-foot and 315-foot levels. 

 By May 12, 1912, the mill had been moved to placer claim #11 above Discovery on 

Cleary Creek, about 4,000 feet northeast of and 600 feet lower than the Newsboy mine. 

Water for the mill was taken from a 100-foot-deep 6-inch well, located near the mill 

(Smith, 1913; B 525). 

 By 1913, the Newsboy mine was being developed on the 60-, 115-, 168-, 215- and 315-

foot levels. The 115-foot level extended 140 feet southwest and 100 feet northeast of the 

shaft and much of the ore between this level and the 168-foot level had been mined 

(Chapin, 1914). A few feet east of the shaft on the 115-foot level the shear zone was 

LG100 
Alaska Resource Data File 

Page 212 

mined over a 14 foot width. The 315-foot level was accessed by 250 feet of drifts, but 

this level of the mine was flooded in 1913 (Chapin, 1914). 

 Surface trenching was conducted along the shear zone in 1923 but the mine was idle 

(Stewart, 1923). During 1931, renovation was completed on the mine and the old mill on 

upper Cleary Creek (Pilgrim, 1932; Smith, 1933; B 836), and the shaft was opened to the 

160-foot level (Hill, 1933). In October, the nearly retrofitted mill burned to the ground. 

Development work continued in the mine and de-watering was begun in the lower mine 

levels (Pilgrim, 1932; Stewart, 1933; Hill, 1933). 

 In 1932, a diesel-powered 180-cubic-foot-capacity Sullivan compressor was installed at 

the mine. One-hundred and fifty tons of ore from above the 215-foot level was shipped 

seven miles to the Tom Gilmore Mill on Fairbanks Creek. The 215-foot level was reopened in 1932 and minor exploratory work was conducted in 1933 (Smith, 1934; B 864). 

The Newsboy mill was rebuilt in 1933. New grinding and flotation equipment was added 

to the mill in 1935 and mining resumed underground (Smith, 1938). In 1938, the mine 

was de-watered at the 215-foot level (Reed, 1939). A 1200-foot-long surface trench was 

emplaced and drifting on the 165-foot level took place in 1938; no ore was produced in 

1938 (Stewart, 1939). In December, 1940, the prospect was idle (Stewart, 1941). 

Production notes:

 In May of 1911, the Newsboy mine produced a 66 ton ore shipment which yielded 

$5008.20 in gold, or about 244 ounces of gold. An additional 7.5 tons of ore was shipped 

in 1911 to the Garden Island Mill in Fairbanks and was reported to contain $104 gold per 

ton (5 ounces of gold per ton) in free milling gold (Brooks, 1913; Smith, 1913, B 525). 

Drifting and mining continued at the Newsboy mine in 1913 although no production figures for the year are available (Chapin, 1914). Despite production of nearly $150,000 

worth of gold (7250 troy ounces), the mine was shut down in 1915. In 1932, 150 tons of 

ore from above the 215-foot level was shipped 7 miles to the Tom Gilmore Mill on Fairbanks Creek. The total estimated production from 175 feet to the surface is 35,937 tons 

of ore and 8,125 tons of waste from which 35,937 troy ounces of gold were recovered 

(Freeman, 1992). 

Reserves:

 The following discussion of reserves is taken from Freeman (1992) and is based on 

analysis of old mine maps. Ore reserves blocked out between the 350-foot and 175-foot 

levels are estimated at 21,875 tons of ore, 10,937 tons of waste and 21,875 ounces of gold 

in place. The estimated potential ore reserves on the Newsboy shear zone system on the 

Newsboy prospect are considerably larger. Based on the past production figures, an estimated 75% of the reserves will consist of 4 feet of shear zone in a 6 foot heading; the remaining 25% of the reserves are figured on a 14 feet wide shear zone on 14 feet of heading. Reserves are based on free gold at a grade of 0.5 ounces of gold per ton. Sulfideencapsulated fine gold is expected to contribute a significant amount to the total gold, 

however, since reliable figures on the average amount of sulfide-encapsulated gold are 

not available, no value is given to this form of gold in the geologic reserves. The adjusted 

total geologic reserves takes into account the 44,062 tons of ore and waste estimated to 

have been mined from the Newsboy shaft. Based on the above assumptions, the total 

geologic reserve of the Newsboy shear zone system to the 1200' elevation is 813,938 tons 

LG100

at a grade of 0.5 ounces of gold per ton. It should be noted that the reserves are hypothetical reserves (USBM nomenclature) and as such no dilution or recovery factors have been 

included in the calculations.

Geologic description:

 The shear zone at the Newsboy Extension shear trends N 15 E and dips 77 NW, 

whereas the Newsboy shear (described in Newsboy mine, ARDF no. LG100) strikes N 40 

E and dips 73 NW (Smith, 1913; B 525). The ore is similar in character to that from the 

Newsboy mine but contains less free quartz. 

 Considerable development work was completed on the Newsboy extension in 1911 

(Brooks, 1912). The mine was worked from a 115-foot deep shaft with short production 

drifts at the 60-foot level. The ore was reported to average about $15 per ton in free milling gold (0.72 ounces of gold per ton) (Smith, 1913; B 525). The mine was inactive and 

the shaft flooded by 1913 (Chapin, 1914). Hill (1933) indicated that the prospect had 

been idle for 20 years and none of the workings were accessible.

Geologic description:

 In 1942, a placer cut on Willow Creek exposed high-grade stibnite in several parts of a 

wide quartz zone (Joesting, 1943). The vertical vein of stibnite with occasional quartz 

and other sulfides is 6 to 8 inches wide and was traced N 40 E for 75 feet (Killeen and 

Mertie, 1951). Nearby in 1912, a shaft was sunk 16 feet on a narrow quartz stringer carrying stibnite (Killeen and Mertie, 1951). Massive stibnite was identified on the dumps at 

the Johnson and Martin prospect with coarse grained scheelite (Byers, 1957). The prospect was examined by Metz and Robinson (1980) who noted that massive stibnite and 

scheelite were in quartz muscovite schist striking N 60 E and dipping 25 NW. Ore exposed in a 28-inch-thick horizon in a small pit on the prospect contained abundant coarseto fine-grained stibnite, discrete bands of coarse scheelite grains to 0.8 inches across, and 

minor pyrite and arsenopyrite. By volume, stibnite constitutes 95% of the lens, scheelite 

4% and arsenopyrite and pyrite constitute 1% each. 

 In 1986 the prospect was examined by Fairbanks Exploration Inc. (Fairbanks Exploration Inc., unpublished report, 1986). The deposit consisted of disseminated to massive 

coarse-bladed stibnite with coarse-grained scheelite crystals disseminated in the stibnite. 

Gold values ranged from 420 ppb to 2450 ppb, silver values ranged from trace to 2.21 

ounces of silver per ton, antimony values were greater than 10,000 ppm and arsenic values ranged from 600 to 800 ppm. Extensive trenching was conducted by Yukon Tanana 

Mining Company in the vicinity of the Johnson and Martin prospect in 1988, however the

Geologic description:

 The Chechako prospect contains two types of mineralization: lead, zinc and silver mineralization in flat-lying replacement bodies in marble and high angle shear-related mineralization which cuts the replacement bodies and is composed of complex sulfosalts containing antimony, arsenic and lead (Kent, 1985). The shear-hosted mineralization has 

been traced for 2800 feet along strike. Average grade of composite samples from this material was 14.4% lead, 2.06% zinc, 7.3% antimony, 13.7 ounces of silver per ton, 0.268 

ounces of gold per ton, and variable arsenic (Kent, 1985). Geophysical surveys indicated 

the bedded sulfide horizon extended to the north and was down-dropped by the main 

shear zone indicating normal motion on the Chechako shear zone. Average grade of composite samples from the bedded replacement mineralization was 27% lead, 20% zinc, 1% 

antimony, 60 ounces of silver per ton, and 0.092 ounces of gold per ton (Kent, 1985). 

 In July, 1980, approximately 186 dry tons of sorted ore was extracted from the oxidized 

portion of the Chechako shear zone; it averaged 0.07 ounces of gold per ton, 37.87 ounces 

of silver per ton, 18.98% Pb, 2.00% Zn, 2.61% Sb, and 1.83% As (Fairbanks Exploration 

Inc., unpublished report, 1985). Gold values appear to be higher in the unoxidized portion of the exposed lode than in oxidized ore shipped in 1980. Separation of sulfide versus oxide ore indicates the Chechako prospect carries average grades of oxidized ore of 

0.07 ounces of gold per ton, 37.87 ounces of silver per ton, 18.98% Pb, 2.00% Zn and 

LG107

2.61% Sb; unoxidized ore averages of 0.20 ounces of gold per ton, 25.20 ounces of silver 

per ton, 22.50% Pb, 3.77% Zn, and 7.80% Sb (Fairbanks Exploration Inc., unpublished 

report, 1985). 

 Sampling of the exposed workings on the Chechako prospect was conducted by Fairbanks Exploration Inc. in 1986 (Fairbanks Exploration Inc., unpublished report, 1986). 

Silver values ranged up to 87 ounces per ton while gold values ranged up to 3400 ppb 

(0.1 ounces of gold per ton). Elevated arsenic (+1000 ppm) and antimony (+10000 ppm) 

values also were noted. Mineralization is most intense peripheral to high angle normal 

faults which cut the marble. Weak prograde skarn alteration in the form of pyroxene, 

diopside and biotite replacement is associated with blackjack sphalerite in marble units 

(Fairbanks Exploration Inc., unpublished report, 1985). 

 In 1988 and 1989, Yukon Tanana Mining conducted extensive surface trenching on the 

Chechako and adjoining Tolovana mine prospects and outlined a surface mineable gold 

reserve of about 150,000 ounces (J. Blakestad, oral commun., 1991). 

 In 1998, three holes were drilled in the Chechako area to invesitgate extremely high 

grade gold values that were found in soils (Freeman and others, 1998). On one 400 ppb 

soil anomaly, a drill hole intercepted 10 feet with 0.096 ounces of gold per ton and another 10 feet with 0.064 ounces of gold per ton. Another hole intercepted 20 feet with 

0.037 ounces of gold per ton, 5 feet with 0.066 ounces of gold per ton, and another 5 feet 

with 0.041 ounces of gold per ton.

 A 30-foot deep shaft was sunk on the prospect in 1910 but the prospect was inactive 

when visited in 1912 (Smith, 1913; B 525). By 1916, the prospect was being actively 

mined from an open cut and a 40-foot deep shaft (Mertie, 1918). The shaft was 45 feet 

deep with 30 feet of adjoining drifts and stopes by 1917 (Martin, 1919). By 1922, the 

prospect had two shafts which exposed a 3- to 5-foot-wide shear zone striking N 35 E and 

dipping 85 NW. (Stewart, 1922; Davis, 1922). The southwest shaft was 45 feet deep with 

a 30-foot drift to the southwest and a 45-foot drift to the northeast at the 45-foot level. 

From the 15- to the 40-foot station in the northeast drift, ore had been stoped out over a 

12-foot height and 20-foot width. The northeast shaft is located 200 feet along strike 

LG107

from the southwest shaft and was sunk to a depth of 35 feet by 1922. A drift extends 45 

feet to the southwest from the 35-foot level. Two adits had been driven an unknown 

length on the prospect between 1922 and 1931. These two adits and both previously described shafts were inaccessible in 1931 (Hill, 1933). 

 The Chechako prospect was examined as a possible source of antimony in 1942 but no 

additional exploration was conducted due to low antimony values in the ore (Killeen and 

Mertie, 1951). 

 In 1981, the Chechako prospect was leased to Placid Oil Company who conducted soil 

sampling, VLF and CEM ground geophysics and drilled 462 feet in three diamond drill 

holes (Porterfield and Croff, 1986). In 1998, three holes were drilled in the Chechako area 

to invesitgate extremely high grade gold values that were found in soils (Freeman and 

others, 1998). 

Production notes:

 Two shipments of ore from the prospect in 1916 totalled 24 tons and contained 3.67 

tons of lead (15%) and 1,083 ounces of silver (45 ounces of silver per ton) (Smith, 1917; 

BMB 153). In July, 1980, approximately 186 dry tons of sorted ore from the prospect 

were shipped to the Asarco smelter at East Helena, Montana (Fairbanks Exploration Inc., 

unpublished report, 1985). 

Reserves:

 In 1988 and 1989, Yukon Tanana Mining conducted extensive surface trenching on the 

Chechako and adjoining Tolovana mine prospects and outlined a surface mineable gold 

reserve of about 150,000 ounces (J. Blakestad, oral commun., 1991).

strikes east-west, across the valley of Willow Creek (Joesting, 1942; ATDM PE 49-7). In 

the hydraulic cut, where the overburden and gravel have been removed, high-grade ore 

could be traced continuously from the west side of the cut to the creek, a distance of about 

75 feet. Ore is also found on the east side of the cut, about 100 feet from the creek. Between these two showings of ore, the zone consists mainly of quartz and gouge, with minor amounts of stibnite and pyrite, and occasionally arsenopyrite. Some pieces of highgrade stibnite found on the surface measured about a foot across. Most of the ore is finegrained and massive with a minor portion made up of coarse bladed crystals. The higher 

grade portions contained 56 percent antimony. Small amounts of pyrite and arsenopyrite 

occur in the lower grade material. 

 The bedrock is mainly a soft, badly weathered mica schist, containing considerable clay. 

The schist strikes east-west and dips steeply north. Several thin limestone beds were 

noted. A few of these beds, about 100 feet upstream from the stibnite, contain sphalerite 

and pyrite. Numerous small veins and lenses of quartz were also noted in the bedrock. 

Most veins are glassy, but some contain small amounts of pyrite, arsenopyrite, and 

sphalerite.

Geologic description:

 The Tolovana Mine is an old property that was first discovered before 1910. It operated 

intermittently until at least 1949, and was the site of considerable work in the 1980's. 

 Three different metamorphic rock types are visible at the Tolovana prospect 

(LeLacheur, 1991). The dominant rock unit is a micaceous quartzite. A layer of crenulated biotite-schist and a thin layer of amphibole-biotite schist are enclosed between the 

quartzite layers. Strongly altered plutonic rock is exposed in several trenches at the south 

end of the property (LeLacheur, 1991). The dominant process of ore deposition seems to 

have been replacement of the country rock and fault products by quartz, sericite and sulfides, rather than vein quartz deposition (LeLacheur, 1991, p. 50). Mineralization occurs 

within fault gouge zones cutting through micaceous quartzite. 

 Initial development began on a series of 1- to 3-inch quartz veinlets which trend N 75 E. 

These stringers contained visible gold and in one case a barren quartz-albite stringer was 

found suggesting an igneous affinity (Prindle, 1910). Ore in the Tolovana mine varies 

from ribbon texture quartz stringers to massive quartz zones which vary from a few 

inches to 3 feet in width. The mineralization had been traced for over 1,500 feet along 

strike. The Tolovana shear zone strikes east-west and dips 60 S (Smith, 1913; B 525). 

The 1- to 3-inch quartz stringers are separated by calcareous schist containing disseminated pyrite. The gold-bearing quartz stringers contain euhedral stibnite but do not norLG110 
Alaska Resource Data File 

Page 234 

mally contain pyrite (Smith, 1913; B 525). The gold fineness analyses, conducted 

through 1912, varied from 792 to 824 fine, with the highest silver content being 180 parts 

per thousand from the sample with a gold fineness of 792 (Smith, 1913; B 525). Several 

phases of quartz introduction were noted at the Tolovana prospect with gold being most 

common in a glassy variety which post-dates the more abundant milky white quartz 

(Smith, 1913; B 525). 

 A new shear zone was discovered on the Tolovana mine prospect in mid-1913 (Chapin, 

1914). The occurrence is 100 feet south of the portal of the adit; it strikes east-west and 

dips 50 S. The shear is 18 inches to 36 inches wide and consists of massive white quartz 

with gouge on each contact. This shear is parallel to the shear exposed in the Tolovana 

adit. Shaft sinking was in progress in 1913. This shaft, referred to here as the South 

shaft, was later connected to the Tolovana adit by a cross-cut. 

 The western extension of the Tolovana shear was discovered in 1930 and was developed by the 160-foot Parenteau adit. The Tolovana shear strikes N 30-65 E and dips 30-

60 SE. The mineralization is in 1- to 12-inch wide stringer zones similar to that mined 

from the Tolovana adit. The ore contained gold associated with arsenopyrite, stibnite, pyrite, galena and tetrahedrite (Stewart, 1933; Pilgrim, 1933). 

 The prospect was sampled by Fairbanks Exploration Inc. in 1986 (Fairbanks Exploration Inc., unpublished report, 1986). Backhoe and dozer trenches on the Tolovana prospect exposed a large section of metarhyolite tuff, exhalite and volcaniclastic metaquartzite 

of the upper Cleary Sequence. These rocks contain disseminated and shear-zonecontrolled arsenopyrite, pyrite, stibnite and native gold. The structures which hosted the 

high grade gold-quartz shear zones in the old Tolovana mine trend predominantly N 60-

80 E and dip steeply southeast; they transect the flat-lying, northeast-trending Cleary Sequence. Samples collected in the Upper Pit area were chip samples across exposures of 

sulfide-bearing metarhyolite tuff units cut by numerous 1-6 inch thick white quartz veins. 

Gold values from these samples were 520 to 3600 ppb. Samples from high-grade dump 

material at the small mill set up near the old Tolovana shaft ranged from 0.27 to 0.52 

ounces of gold per ton. The samples consisted of white, massive, quartz vein material 

with 1-3% arsenopyrite and minor stibnite. Country rock welded to the shear zone selvages was metarhyolite similar to that seen in the upper pit area. As a check on the efficiency of the old gravity milling circuit used in the Tolovana mill, a sample was collected 

from the tailings pond below the mill. This sample consisted of coarse sand-size material 

(20-30 mesh); it contained mainly quartz, arsenopyrite, pyrite and stibnite. The sample 

assayed 0.458 ounces of gold per ton, suggesting that the mill did a poor job of recovery 

of the fine gold in the ore (Fairbanks Exploration Inc., unpublished report, 1986). 

 In 1988 and 1989, Yukon Tanana Mining conducted extensive surface trenching on the 

Tolovana and adjoining Chechako prospects and outlined an estimated 150,000 ounces of 

gold that could be mined from the surface pit (R. Blakestad, oral commun., 1991). 

Alteration:

 Pods and disseminations of jamesonite occur in an amorphous, green vuggy matrix in 

the walls surrounding the gouge zone (LeLacheur, 1991). Quartz, sericite, ankerite and 

carbon alteration also present.

Workings/exploration:

 By 1910, an 85 foot adit had been driven. In July, 1911 a Huntington disc mill was installed and began operation on the prospect. The mill ran continuously through midNovember when lack of water forced it to close. The mill began operating again in 

March, 1912 after a well and pump had been installed on Willow Creek (Times Publishing Company, 1912). In July, 1912 a two stamp Nissen mill was erected and began 

crushing ore on August 23, 1912. 

 In 1912, the mine consisted of a 400 foot adit from which several short drifts were 

driven; small stopes were also developed (Smith, 1913; B 525). The adit extends along 

the main shear zone for 130 feet where it intersects a vertical fault. The workings turn 

north for 30 feet and then turn east again along the offset extension of the shear zone. 

Approximately 100 feet from the portal of the adit, a winze was sunk to a depth of 50 feet 

and drifts driven to the east and west. A second winze inclined at 60 degrees south was 

driven from the east end of the drift but was flooded in 1912. A second winze, located 

330 feet from the portal, was sunk from the adit level to a depth of 100 feet (Loftus, 

1927). A shaft near the adit portal had been sunk to a depth of 100 feet and a drift driven 

on the 50-foot level connects with the winze in the adit. Due to flooding of the shaft near 

the Tolovana adit in late 1912, work was shifted to the Willow Creek-Bedrock Creek divide where a 55 foot shaft, referred to here as the Scheuyemere #1 shaft, was sunk on a 

12- to 14-inch-thick shear zone (Times Publishing Company, 1912). This shaft is sometimes referred to as the Tolovana Stibnite prospect (Chapin, 1914). 

 By 1913, the shaft and the winze had been connected by a drift on the 100-foot level 

and the ore between the adit and the 100 foot level was mined (Chapin, 1914). Additional stoping took place above the adit level. The Scheuyemere #1 shaft had been sunk 

to a depth of 100 feet by 1913 and drifting had been conducted for 50 feet to the east and 

30 feet to the west on the 50-foot level (Chapin, 1914). A raise located 24 feet west of 

the shaft connected with the surface and the block of ground between the shaft and the 

raise had been stoped from the 50 foot level to the surface. 

 In 1913, a new shear zone was discovered and shaft sinking was in progress (Chapin, 

1914). This shaft, referred to here as the South shaft, would be connected to the Tolovana 

adit by a cross-cut drift. 

 In 1922, the Tolovana adit was 530 feet long. A drift had also been driven from the 50 

foot level of the winze for 30 feet to the east where it intersected a fault which offsets the 

shear zone 30 feet to the north (Stewart, 1922; Davis, 1922). In the South shaft, drifting 

at the 50-foot level went out 15 feet to the west and 20 feet to the east along the shear 

zone. A total of 150 feet of new drifting was completed on the Tolovana prospect in 1923 

LG110

and 8 to 10 tons of ore milled on site (Stewart, 1923). 

 The Tolovana mine remained inactive until 1930 when exploration was renewed 

(Smith, 1933; B 836). The western extension of the Tolovana shear, on the west side of 

Willow Creek, was discovered in 1930 and was referred to as the Parenteau adit (Stewart, 

1931). This adit had been driven 160 feet to the west and 50 tons of ore had been treated 

in the mill in 1930. The Parenteau adit had caved about 75 feet from the portal when visited in 1931 (Hill, 1933). 

 Antimony and gold were mined from the prospect in 1949 (Saarela, 1950). 

 In August 1984, dozer and backhoe exploration of the prospect was conducted. A small 

gravity mill was constructed on the prospect near the old portal of the Tolovana adit and 

several large open cuts were excavated in the vicinity of the Scheuyemere #1 shaft 

(Freeman, 1992). Surface samples of the Upper pit area and the dump were also collected 

in 1986 (Fairbanks Exploration Inc., unpublished report, 1986). 

Production notes:

 Ore was shipped from the prospect as early as 1909 (Times Publshing Company, 1912). 

Production through 1912 averaged $20 to $105 per ton (1 to 5 ounces per ton gold) 

(Smith, 1913; B 525). In 1923, 8 to 10 tons of ore were milled on site, averaging $16 

gold per ton (0.8 ounces of gold per ton) (Stewart, 1923). A small amount of ore was 

milled in 1924 and in 1931(Stewart, 1923; Pilgrim, 1932; Smith, 1933, B 844). Antimony and gold were mined in 1949 (Saarela, 1950). 

Reserves:

 In 1988 and 1989 Yukon Tanana Mining conducted extensive surface trenching on the 

Tolovana and adjoining Chechako prospects and outlined a reserve of about 150,000 

ounces of gold that could be mined from a surface pit (R. Blakestad, oral commun., 

1991).

Geologic description:

 In 1995, Freegold discovered significant disseminated gold mineralization in the granodiorite and tonalite of the Dolphin stock (Freeman and others, 1998). Additional soil sampling conducted in 1995 and 1996 delineated a large northeast trending gold anomaly 

(+100 ppb gold) which closely mimics the south contact of the Dolphin stock. The mineralization is controlled by the district-scale Dolphin shear zone. The gold-in-soil anomaly 

also is highly anomalous in silver, arsenic, lead, antimony and zinc. The anomaly forms 

the southeast portion of a broad gold-in-soil anomaly which extends from the west bank 

of Willow Creek to Bedrock Creek. 

 The Dolphin stock forms an elongate northeast-trending exposure of equigranular biotite granodiorite covering a 2,000 foot by 1,200 foot area at the surface. Drilling along 

the northern edge of the stock encountered calc-silicate skarn at a vertical depth of 400 

feet, suggesting the north edge of the stock dips steeply north . The southern contact of 

the stock dips shallowly to the south. Drilling on the northeast end of the intrusive suggests that the main stock branches into a dike swarm in that area and that the main stock 

may be faulted at depth. Mineralization is open to the west into Willow Creek and below 

1000 feet, the deepest hole drilled on the deposit. 

 During 1995-96, Freegold conducted 15,559 feet of reverse circulation drilling in the 

Dolphin prospect in 46 drill holes. In 1998, a single vertical core hole was drilled to a 

LG112 
Alaska Resource Data File 

Page 240 

depth of 1,033 feet. This hole encountered only intrusive rock over its entire length and 

both compositional phases of the Dolphin stock were encountered. Upper portions (0-622 

feet) of the intrusive consisted of granodiorite while tonalite was encountered below 622 

feet. The tonalite phase is texturally similar to the main granodiorite body but with abundant biotite and possible amphibole. The contacts of both the dikes and the main stock 

were loci for well developed brittle fracturing as evidenced by abundant crushed quartz 

and clay. The tonalite has a distinctive geochemical signature of relatively elevated Ni, 

Li, K, Na, Mg, V, Sc, and Ti. A chloritic and sericitic altered intrusive has also been recognized; given the chlorite content, the rock likely represents altered tonalite. 

 Most of the visible sulfide mineralization is in the form of arsenopyrite, pyrite, stibnite, 

pyrrhotite, and pentlandite. As would be expected the pyrrhotite and pentlandite has only 

been recognized in the mafic tonalite and does not seem to be associated with the quartz 

veining. Significant intervals of rock with more than 0.03 ounces of gold per ton were 

encountered at depths well below previous drilling, and the hole bottomed in anomalous 

gold mineralization. 

 Sulfide mineralogy is dominated by 1 to 5% disseminated pyrite and arsenopyrite, and 

pervasive zones with more than 50% sulfides are characterized by large amounts of galena, tetrahedrite and sphalerite. Up to 2% disseminated scheelite is locally abundant. 

Electron microprobe analyses and polished section microscopy reveal native gold and bismuthinite as inclusions in arsenopyrite. Visible gold is rare and is hosted in white, quartz 

stockwork veins in drill cuttings and core. Preliminary metallic sieve analyses also suggest little or no nugget effect (Adams, 1997). Bottle roll analyses from granodiorite in the 

oxide zone recovered 82% to 92% of the gold, while analysis of the sulfide-rich altered 

granodiorite recovered less than 10%. 

 Gold grade at the Dolphin prospect is controlled by the thin quartz veinlets, typically 

less than 1 mm, which cut the host intrusive. Vein orientations vary with no apparent 

preferred orientation for mineralization. At least three separate hydrothermal events are 

present in the Dolphin core. The Dolphin deposit consists of multiple flooded zones of 

alternating silicification and sericitization, with local scheelite-bearing carbonate zones 

and sulfide rich zones containing elevated base metal values. Scheelite-bearing carbonate 

alteration zones generally contain lower gold values and tend to form halos around the 

higher grade gold intercepts. Silica flooding occurs throughout the intrusive and locally 

reaches up to about 90% SiO2. Silica flooded zones often contain chalcedonic green, 

brown or black quartz. In some drill holes the flood silicification in granodiorite results 

in near-complete obliteration of original igneous textures. Chloritic alteration is rare. 

 Preliminary resource calculations estimated a gold resource of approximately 600,000 

ounces grading 0.020 ounces of gold per ton (Adams, 1997).

Geologic description:

 The Wyoming shear zone consists of quartz veins up to 2 feet thick containing gold, 

stibnite and scheelite. Scheelite was particularly abundant in the wall rocks and on shear 

margins (Moffit, 1927). The shear zone strikes N 80 E and dips 50 S (Hill, 1933). Ore in 

the main stope averaged about $6.00 of gold per ton (0.3 ounces of gold per ton) and consisted of 12 to 14 inches of hard white quartz and brecciated schist with minor iron-oxide 

stains (Hill, 1933). 

 The Wyoming prospect was investigated in 1943 as a possible souce of tungsten (Byers, 

1957). Scheelite is present in limestone lenses found east of the north-south fault in both 

the Wyoming and Lower adits. By 1943, the Wyoming adit consisted of 350 feet of drift 

west of the north-south fault, a 100 foot crosscut drift to the south on the east side of the 

north-south fault, and 200 feet of drift along the Wyoming shear from the end of the 100-

foot crosscut (Byers, 1957). A 70-foot section of the 200-foot drift east of the fault averaged 0.3% tungsten oxide over 6 inches. In a sublevel stope above the same zone, a 1-

foot by 3-foot area averaged 20% tungsten oxide in a limestone replacement body (Byers, 

1957). Samples found on the Lower adit dump, and samples collected in place from the 

Wyoming shear in the Lower adit, varied from 0.28% to 1.64% tungsten oxide with trace 

molybdenum, manganese, antimony and arsenic. 

 Fairbanks Exploration Inc. conducted 11 man-days of field work on the Wyoming prospect in 1987. Nineteen rock samples were collected and the alteration zones were 

LG118

Page 253 

mapped. Several samples were collected from bedrock exposures and dumps in and 

around the Wyoming mine site (Fairbanks Exploration Inc., unpublished report, 1987). 

These samples returned low Au, Sb and Ag values and elevated As values. Gold values 

were higher where jamesonite and/or boulangerite are visible in the shear zone. Most of 

the dump material on the Wyoming dump is sulfide-free, white quartz, attesting to close 

grade control during mining. Stratiform arsenopyrite lenses up to 4 inches thick were discovered on bedrock exposures in a placer cut below the Lower adit dump. These occurrences were associated with rhyolitic tuff beds and returned unexpectedly low gold values 

(Fairbanks Exploration Inc., unpublished report, 1987). 

 In 1989, Fairbanks Exploration Inc. conducted 10 man-days of field work on the prospect and collected eighteen rock samples (Fairbanks Exploration Inc., unpublished report, 

1989). Exposures in the old placer cut on lower Bedrock Creek consist of pale-yellow to 

gray, thinly bedded, felsic volcanic tuff and siliceous exhalite containing quartz, sericite, 

minor chlorite and disseminated pyrite and lesser arsenopyrite. These units are correlative with the upper third of the Cleary Sequence. Foliation in this area trends N 60-80 E 

and dips 10 to 20 SE. The rocks are heavily jointed and appear to have undergone minor 

dip-slip deformation along sericite-rich bedding planes. Sulfide mineralization is concentrated along stratiform horizons which vary from one inch to over six inches in thickness. 

Visible gold was found in one of these horizons early in 1989 after heavy rains exposed 

new outcrops in this area. Sulfide contents in the exhalite beds range from 5% to 25% of 

the rock; the ground mass consists of fine-grained quartz, and clay after feldspar. 

 Sample results from the 1989 program indicate that highly anomalous gold and arsenic, 

weakly anomalous antimony, lead and zinc are associated with felsic tuff and exhalite 

over the entire area exposed along the creek bottom and side walls of lower Bedrock 

Creek (Fairbanks Exploration Inc., unpublished report, 1989). The extent of this mineralization on the prospect is unknown.

 By 1909, development work had begun on the Wyoming shear zone (Prindle, 1910).

By the end of 1910, 300 feet of adit had been driven on the Wyoming shear and 50 feet of 

shaft had been sunk on the Carlisle Fraction claim which was adjacent to the Cleary Hill 

mine on the west (Brooks, 1911). At the 80-foot station of the Wyoming adit, a 50-foot 

winze was sunk at an angle of 60 degrees south, but was flattened to 49 degrees south 

near the bottom of the winze (Smith, 1913; B 525). An unknown amount of material 

from the winze was custom milled and reportedly returned high values in gold. 

 In 1913, surface mining was conducted on the Wyoming prospect. Four tons of ore 

were custom milled at the Blue Moon Mazeppa mine on Chatham Creek and another 4.5 

tons was stockpiled (Chapin, 1914). No production records are available for these two 

shipments. Limited development was carried out at the Wyoming prospect in 1914. In 

1915, development activities continued on the Wyoming shear and were expanded to the 

Colorado shear located about 500 feet north of and parallel to the Wyoming shear 

(Stewart, 1915). Thirty-nine tons of ore from these two shear zones were custom milled 

at the Blue Moon Mazeppa mill on Chatham Creek but no production figures are available. Development of the Wyoming prospect was discontinued by 1916 (Brooks, 1918) 

but limited mining was conducted on the prospect in 1917 (Martin, 1919). 

 Development work on the Wyoming adit began again in 1921 when the adit was lengthened and a 60-foot winze sunk from the adit level (Brooks, 1921). The Wyoming shear 

was traced onto the adjacent Alabama claim in 1922 (Davis, 1922; Stewart, 1922). By 

1923, the Wackwitz brothers erected a small, ball mill and mined a limited amount of 

high grade ore from the Wyoming adit. Ore grades averaged $10-20 per ton in gold (0.5 

to 1.0 ounces of gold per ton) with recovery estimated at 85% (Loftus, 1927). The prospect was operated by the Gustafson brothers in 1924 and produced a small amount of gold 

(Smith, 1926). A new ball mill was installed in 1925 and operated for one month. 

 By 1927, the Wyoming shear was intercepted by three adits, the Lower, Wyoming 

(upper) and Crawford adits, for a total of 500 feet of workings over 150 vertical feet of 

shear zone (Loftus, 1927). Production continued in 1927, and ore was milled at the 

nearby Cleary Hill mill (Smith, 1930; B 810). Development work increased and surface 

facilities were improved in 1928 (Smith, 1930; B 810). Minor production from the prospect continued in 1929 and 1930 (Smith, 1932; Smith, 1933, B 836). By 1930, developments at the Wyoming mine consisted of the 165 foot long Wyoming adit and a Lower 

adit 1000 feet long situated approximately 100 feet lower than the Wyoming adit 

(Pilgrim, 1931; Stewart, 1931). The Crawford adit was 75 feet long and approximately 

40 feet above the Wyoming adit. By 1931, the fourth adit had been driven 60 feet on a 

gold-quartz shear zone parallel to the Wyoming shear zone (Pilgrim, 1931; Stewart, 

1933). 

 In 1931, the Wyoming adit was caved and inaccessible. The Lower adit followed the 

Wyoming shear zone for 300 feet at which point the shear was faulted about 100 feet 

south (Hill, 1933). A raise connected the Lower and Wyoming adits. A stope about 70 

feet along strike was extended from the Lower to the Wyoming adit and appears to rake 

about 45 degrees to the west (Hill, 1933). Development work in the Crawford adit followed a north-dipping shear zone which is separate from the Wyoming shear. 

 Reed (1939) reported that in 1938 Fred and Ernest Wackwitz completed 30 feet of drifting, 20 feet of cross-cuts, 125 feet of adit and milled 56 tons of ore with an average grade 

of $47 per ton in gold (1.34 ounces of gold per ton). The ore was milled on site in a 20 

ton Herman ball mill. By 1943, the Wyoming adit consisted of 350 feet of drift west of 

LG118 
Alaska Resource Data File 

Page 255 

the north-south fault, a 100 foot crosscut to the south on the east side of the north-south 

fault, and 200 feet of drift along the Wyoming shear from the end of the 100-foot crosscut 

(Byers, 1957). 

 In 1987, Fairbanks Exploration Inc. conducted eleven man-days of field work on the 

Wyoming prospect. Nineteen rock samples were collected and an alteration map prepared. Several samples were collected from bedrock exposures and dumps in and around 

the Wyoming mine site (Fairbanks Exploration Inc., unpublished report, 1987). In 1989, 

Fairbanks Exploration Inc. conducted ten man-days of field work on the prospect and 

collected eighteen rock samples (Fairbanks Exploration Inc., unpublished report, 1989). 

Alteration and geologic mapping was also conducted in the old placer cut on lower Bedrock Creek. 

Production notes:

 Smith (1913, B 525) reported that production began by 1913 with an unknown amount 

of material being custom milled from the Wyoming adit. In 1913, surface mining was 

conducted on the Wyoming prospect. Four tons of ore were custom milled at the Blue 

Moon Mazeppa mine on Chatham Creek and another 4.5 tons was stockpiled by August, 

1913 (Chapin, 1914). No production records are available for these two shipments. By 

1915, development activities continued on the Wyoming shear and were expanded to the 

Colorado shear located about 500 feet north of and parallel to the Wyoming shear 

(Stewart, 1915). Thirty-nine tons of ore from these two shear zones were custom milled 

at the Blue Moon Mazeppa mill on Chatham Creek but no production figures are available. 

 By 1923, the Wackwitz brothers erected a small, ball mill and mined a limited amount 

of high grade ore from the Wyoming adit. Ore grades averaged $10-20 per ton in gold 

(0.5 to 1.0 ounces of gold per ton) with recovery estimated at 85% (Loftus, 1927). Production continued in 1927, and ore was milled at the nearby Cleary Hill mill (Smith, 

1930; B 810). Minor production from the prospect continued in 1929 and 1930 (Smith, 

1932; Smith, 1933, B 836). Reed (1939) reported that 56 tons of ore were milled with an 

average grade of $47 per ton in gold (1.34 ounces of gold per ton).

Geologic description:

 The Cleary Hill mine was the largest lode gold producer in the Fairbanks mining district, prior to the first production from the Fort Knox gold mine in 1996. The average 

grade of gold produced was approximately 1.3 ounces of gold per ton. Recent drilling in 

the 1990's has shown that the Cleary Hill mine still has an approximate resource of 

100,000 ounces of gold with a grade of 0.81 ounces of gold per ton. 

 In the early 1900's, gold was reported to be found in quartz veins within schist with 

quartz stringers (Prindle, 1910). Visible gold was found in quartz veins that were largely 

free of sulfides (Smith, 1913; B 525). The principle vein averages about 1 foot in thickness with a maximum thickness of about 3 feet. There are smaller, similar, parallel veins 

in both the hanging and footwalls; the veins are crushed, cross the foliation of schist 

country rock, and are complexly faulted (Smith, 1913; B 525). 

 The Cleary Hill Mine is hosted in mafic volcanics, quartzites and quartz muscovite 

schists on the north flank of the Cleary antiform (Freeman and others, 1998). The Cleary 

Hill vein strikes N 70-80 W and dips 45 to 70 S. The dip of the vein varies according to 

the host rock, with steeper dips in more competent rock units and shallow dips in less 

competent rock units (Freeman and others, 1998). The mine consisted of over six levels 

that produced ore from quartz veins that contained coarse free gold, and trace arsenopyrite, pyrite, boulangerite, and tetrahedrite. Higher grade intervals have gold values from 

LG119 
Alaska Resource Data File 

Page 258 

the hundreds to the thousands of ounces of gold per ton. These intervals are commonly 

associated with acicular needles and felted masses of boulangerite and jamesonite, in 

white to gray quartz veins that are 1 to 5 feet thick (Freeman and others, 1998). 

 During the 1986 field season, the mine waste dumps of the Cleary Hill mine were examined and grab samples were collected by Fairbanks Exploration Inc. (Fairbanks Exploration Inc., unpublished report, 1986). Quartz vein samples on the Penrose and Upper 

adit dumps are associated with chlorite-actinolite schists of mafic volcanic origin, typical 

of the the lower third of the Cleary Sequence. Dump samples contained arsenopyrite, pyrite, stibnite, jamesonite, native gold, and minor scheelite hosted by quartz-bearing shear 

zones and stockworks with thin argillized selvages. Significant ankerite occurs in some 

shear zones and weathers to a bright ocherous, red color. Visible gold is usually associated with jamesonite needles and rosettes similar to mineralization in the Christina adit 

(ARDF no. LG146) and Nordale adit of the Homestake mine (ARDF no. LG157). Up to 

one-half percent scheelite is finely disseminated in chlorite-actinolite schist and less commonly forms coarser grained crystal aggregates in sulfide-free quartz shear zones. Gold 

values vary up to 0.558 ounces of gold per ton and appear to be higher in samples of siliceous exhalite, metarhyolite tuff and carbonaceous quartzite from the lower production 

dumps at the mine. Reserve estimates of the waste dump made by Fairbanks Exploration 

Inc. in 1988 indicated the Cleary Hill mine dumps contained 71,176 tons of rock grading 

0.159 ounces of gold per ton and 0.099 ounces of silver per ton (Fairbanks Exploration 

Inc., unpublished report, 1987; Fairbanks Exploration Inc., unpublished report, 1988). 

 Reverse circulation drilling at the Cleary Hill Mine in late 1996 encountered at least two 

vein systems with values of more than 0.5 ounces of gold per ton over narrow widths below the old underground workings (Freeman and others, 1997). 

 Complete production records are not available for the Cleary Hill mine, however, existing published and private records indicate the Cleary Hill mine produced more than 

100,000 fine ounces of gold from approximately 77,000 tons of material with an average 

grade of 1.3 ounces of gold per ton (Porterfield and Croff, 1986; Metz and others, 1987). 

This ranks the Cleary Hill mine as the largest lode gold producer in the Fairbanks Mining 

District, prior to the development of the Fort Knox mine. 

 Recent drilling shows that Cleary Hill Mine, in addition to a 100,000-ounce resource 

grading 0.81 ounces of gold per ton, has potential for bulk tonnage, lower-grade material 

in the footwall of the high-grade veins (Swainbank and others, 1998).

Workings/exploration:

 Mineralization was first discovered on the Freegold claim prior to 1910, near the juncture of Cleary and Bedrock Creeks. Shortly after discovering the rich surface outcrops of 

the Cleary Hill lode (selected samples assayed up to 5,950 ounces of gold per ton), the 

main production adit was collared about 50 feet above Bedrock Creek (Freeman, 1991). 

 By the summer of 1910 the Main adit had been driven 630 feet on the Free Gold claim 

and a 50 foot shaft with 90 feet of drift was also driven on the main shear zone approximately 800 feet uphill from the Main adit portal (Brooks, 1911). On August 27, 1911, a 

five stamp Joshua Hendy mill, the first private mill in the Fairbanks Mining District, was 

put into production on the Free Gold claim. By the end of 1911 there were about 1,200 

feet of underground workings at the Cleary Hill mine (Brooks, 1911). By 1912 the Main 

adit had been driven over 1,050 feet and a second adit, the 215 foot deep Penrose adit, 

had been driven at an elevation 140 feet higher than the Main adit (Cunningham, 1912). 

The two adits were connected by a 170 foot raise driven 900 feet from the Main adit portal. Over 500 feet of drifting from the Main adit level had developed over 20 stopes. A 

30 foot winze was sunk 650 feet from the main adit portal but water hampered its sinking. 

By the end of 1912, the winze exposed ore 300 feet below the surface outcrops of the lode 

(Cunningham, 1912). By the end of 1913, Brooks and others (1913) stated that the Main 

adit of the Cleary Hill mine was 1,280 feet long, the Penrose adit was 280 feet long and 

the Upper adit was 200 feet long at an elevation 50 feet above the Penrose adit. A total of 

1,000 feet of workings were accessed by the main winze with working drifts at the 70- 

and 112-foot levels. 

 Operating cost allowed only 200 feet of new drifting to be completed in 1915 and the 

mine closed on September 10, 1915 (Brooks, 1915; Stewart, 1915). The Cleary Hill mine 

remained closed until 1924 when it was amalgamated with the neighboring Wyoming 

mine (Stewart, 1923). 

 Efforts to reopen the Cleary Hill mine began in the fall of 1923 and continued through 

1929 (Smith, 1924; Moffit and others, 1927; Smith, 1930, B 813). This work included 

driving a 400 foot adit to access the mine at the 70-foot level of the Main winze. This 

Lower adit was collared at the level of Bedrock Creek near the mill site (Moffit and others, 1927). In addition, the Upper adit was extended to a total length of 900 feet and 538 

feet of crosscuts and a 40 foot raise were extended from this adit (Stewart, 1931). The 

Penrose adit was extended 45 feet (total length 325 feet) and three crosscuts were driven a 

total of 595 feet from this adit. An 89 foot raise was driven to connect the Penrose and 

Upper adits. The Main adit was extended 192 feet (total length of 1,472 feet) and 51 feet 

of drift was driven on the Powder House shear zone while 154 feet of drift was driven on 

the Doget shear zone. At a point near the mill a shaft was driven 185 feet and a crosscut 

extended from the shaft bottom for 280 feet. A shaft was also sunk on the ridge an unknown distance above the Upper adit. This shaft, known as the Deep shaft, was 50 feet 

deep with an 80 foot crosscut at the bottom (Stewart, 1931). 

 The mine was back in production again in 1929 and rapidly became one of the largest 

operations in the district (Smith, 1930, B 810; Smith, 1931). In 1930, mining was concentrated in the Penrose adit (Stewart, 1931) and the Cleary Hill mine was again the largest producer in the Fairbanks Mining District (Pilgrim, 1931). The mill operated for a toLG119

tal of 7 months during 1932 and development was concentrated below the Main adit level 

(Pilgrim, 1933). In 1938 the Cleary Hill mine conducted 250 feet of new drifts and crosscuts, sank 100 feet of winze and drilled 4,200 feet of AX diamond core. 

 No other work was conducted at the Cleary Hill mine until 1969 when International 

Minerals and Chemicals excavated two bull dozer trenches on the expected trace of the 

Cleary Hill shear zone (Pilkington, 1970). This work produced only weakly anomalous 

gold and silver. 

 The mine waste dumps of the Cleary Hill mine were examined and grab samples were 

collected by Fairbanks Exploration Inc. during the 1986 field season (Fairbanks Exploration Inc., unpublished report, 1986). In 1988, Tri-Con Mining conducted bulk sampling 

of the upper and lower Cleary Hill mine dumps to determine if this material could be 

profitably trucked to the Grant mill for processing. 

Production notes:

 The first recorded production from the Cleary Hill mine was on February 9, 1910, when 

a five-ton lot was sent to the Tacoma, Washington, smelter and returned an average grade 

of 22.25 ounces of gold per ton (Times Publishing Company, 1912). On September 7, 

1910, a 17-ton lot of ore from the Free Gold claim averaged 8.61 ounces of gold per ton. 

An additional 75 tons of ore was shipped to the Chena mill in Fairbanks in November, 

1910, followed by a 100 ton lot sent to the Chena mill in early 1911. The grade of this 

material is unknown but reportedly paid for all past development work and a new stamp 

mill (Cunningham, 1912). On June 3, 1912, the Alaska Citizen, a Fairbanks newspaper, 

reported that 147 tons of ore from the Cleary Hill mine were milled at the Chena mill in 

1911. The Cleary Hill mine operated 365 days and the mill operated for 350 days in 1914 

and produced an estimated 5,950 tons of ore from 1,800 feet of productive lode (Brooks 

and others, 1914). Up through 1915, the Cleary Hill mine had produced approximately 

29,000 fine ounces of gold from an estimated 17,000 tons of ore averaging 1.69 ounces of 

gold per ton (Stewart, 1922). Production from 1929 to the end of 1931 was 19,000 

ounces from 9,800 tons grading 1.94 ounces of gold per ton (Hill, 1933). The high grades 

were derived from the Bankers stope between the Penrose and Upper adits. Total production from the mine was estimated at $1,000,000 in gold, or 48,379 ounces, through 1930 

(Pilgrim, 1931). Pilgrim (1932) stated that in 1931 the Cleary Hill mine was the largest 

producer in the district and fourth largest lode producer in Alaska. The Cleary Hill mine 

remained the largest producer in the district in 1934 and 1935 due to additional production from the Main shaft and addition of a flotation circuit in the mill which increased recovery (Smith, 1936; Smith, 1937). Production from the Cleary Hill mine was interrupted in 1936 when a fire destroyed the mill and power plant (Smith, 1938). Production 

levels increased in 1937 due to the more efficient nature of the new mill installed after the 

fire (Smith and Mertie, 1941). A total of 2,085 tons of ore with an average grade of $80 

per ton in gold (2.3 ounces of gold per ton) was milled in 1938 (Reed, 1939). 

 In 1942, the War Powers Act Limitation Order L208 banned all non-essential mining in 

the United States, thereby forcing the closure of the Cleary Hill mine. Shortly after the 

Cleary Hill mine was closed, a 5 ton lot of high grade stibnite ore was shipped to Fairbanks for sale to the federal government (Joesting, 1943). This material was taken from a 

fault intersection just above the Main adit (Killeen and Mertie, 1951). A small amount of 

ore was mined by Doug Jackson and Earl Beistline during 1949 and 1950 from previously

worked areas above the Main adit (Saarela, 1950; Wedow and others, 1954). The Cleary 

Hill mill was rehabilitated and used for custom milling by Adolph, Rudy and Grace Vetter in 1956. 

 Complete production records are not available for the Cleary Hill mine, however, existing published and private records indicate the Cleary Hill mine produced in excess of 

100,000 fine ounces of gold from approximately 77,000 tons of material at an average 

grade of 1.3 ounces of gold per ton (Porterfield and Croff, 1986; Metz and others, 1987). 

This ranks the Cleary Hill mine as the largest lode gold producer in the Fairbanks Mining 

District, prior to the development of the Fort Knox mine. 

Reserves:

 Waste dump reserve estimates made by Fairbanks Exploration Inc. in 1988 indicated 

the Cleary Hill mine dumps contained 71,176 tons of rock grading 0.159 ounces of gold 

per ton and 0.099 ounces of silver per ton (Freeman and others, 1987; Freeman and others, 1988). 

 Recent drilling shows that Cleary Hill Mine, in addition to a 100,000-ounce resource 

grading 0.81 ounces of gold per ton, has potential for bulk tonnage, lower-grade material 

in the footwall of the high-grade veins (Swainbank and others, 1998).

Geologic description:

 The Paupers Dream prospect is a north-south trending shear zone which extends from 

the Paupers Dream claim (MS1639) on the south, through the California claim (MS1639), 

and onto the Texas claim. Where exposed on the Paupers Dream claim, the shear dips 

steeply west and has a high sulfide content, primarily as arsenopyrite (Smith, 1913; B 

525). Free gold was particularly abundant in weathered portions of the shear zone. This 

shear trends across the California prospect to the east of the eastern-most shaft on the 

California prospect (ARDF no. LG121).

Geologic description:

 A shaft was sunk on the California prospect on what was believed to be the extension of

The shaft was sunk 20 feet at a 60 S. dip along the shear zone and then flattened to 40 S. 

for an additional 40 feet (Smith, 1913; B 525). A 1- to 3-foot-wide quartz-bearing zone 

extends nearly to the bottom of the shaft where it is cut off by a flat-lying fault. The ore 

was reportedly of lower grade than other shear zones in the area; production records are 

not available. A second shaft was sunk to an unknown depth east of the first shaft but 

was not accessible in 1912 when visited by Smith (1913, B 525). Dump material at this 

shaft included quartz-feldspar granite which was reportedly associated with a goldbearing shear zone in the shaft.

Geologic description:

 By 1913, a short adit had been driven to explore an east-west trending shear zone that 

dips 25 S. (Chapin, 1914). A short drift was driven on the shear about 25 feet from the 

portal. The quartz-rich portion of the shear is 1 foot thick and contains iron-oxide-stained 

ribbon quartz in brecciated schist and clay gouge. No sulfides were seen in the shear zone 

underground however, quartz on the dumps is stained by antimony oxides. The total 

length of the adit is unknown because flooding made it inaccessible 30 feet from the portal (Chapin, 1914). 

 The prospect was examined in 1942 as a possible source of antimony but was not developed due to insufficient grade and thickness of antimony mineralization (Killeen and 

Mertie, 1951).

Ore minerals: Arsenopyrite, galena, gold, pyrite, sphalerite, stibnite 

Gangue minerals: 

Geologic description:

 Schist in a shear zone contain disseminated arsenopyrite and pyrite along with lesser galena, sphalerite and stibnite. These sulfides also occur in numerous quartz stringers in the 

shear zone. Free gold is more common in the upper oxidized portions of the lode while 

gold appears to be associated with sulfides at depth. Tourmaline is present in the schists 

along the margins of quartz stringers and is strongly correlative with elevated arsenopyrite 

and pyrite (Prindle, 1910). 

 By 1909, a 90-foot-long adit had been driven on the prospect and had intersected a 6-

foot-thick shear zone 50 feet from the portal (Prindle, 1910). A drift was driven from the 

main adit to the northwest along the shear and a 150-foot-deep winze was sunk on the 

shear from this drift. A raise to the surface was later put in above the winze (Prindle, 

1910). Approximately 100 feet below the main adit level drift, a second working level 

was started and drifts driven 40 feet to the northwest and southeast from the shaft, which 

was then known as the Robertson shaft. Brooks (1911) reported the shaft was 160 feet 

deep on a 4- to 8-foot-wide shear zone. Smith (1913, B 525) reported that attempts to develop the Butler and Petree prospect failed due to the low gold and high base metal content on the prospect. In 1931, the prospect was abandoned and the workings were inaccessible (Hill, 1933). The prospect was examined in 1942 as a possible source of antimony but was not developed due to insufficient grade and thickness of antimony values 

(Killeen and Mertie, 1951).

 This prospect was discovered and first staked in October, 1908. By 1909, a 90-foot-long 

adit had been driven on the prospect and had intersected a 6-foot-thick shear zone 50 feet 

from the portal (Prindle, 1910). A drift was driven from the main adit to the northwest 

along the shear and a 150-foot-deep winze was sunk on the shear from this drift. A raise 

to the surface was later put in above the winze (Prindle, 1910). Approximately 100 feet 

below the main adit level drift, a second working level was started and drifts driven 40 

feet to the northwest and southeast from the shaft, that was then known as the Robertson 

shaft. 

 By 1910, the prospect was in litigation which prevented active exploration and development. Brooks (1911) reported the shaft was 160 feet deep on a 4- to 8-foot-wide shear 

zone. The prospect was erroneously referred to as the Rex Mining Company prospect 

which may have been the company in litigation with the owners of the Butler and Petree 

prospect (Freeman, 1992). A minor amount of work was conducted on the Butler and 

Petree prospect in 1911 (Brooks, 1912). Smith (1913, B 525) reported that attempts to 

develop the Butler and Petree prospect failed due to the low gold and high base metal 

content on the prospect. In 1931 the prospect was abandoned and the workings inaccessible (Hill, 1933). The prospect was examined in 1942 as a possible source of antimony

the creek. Stibnite has been found in places as veins a foot or more thick, parallel to the 

structure in the schist ( Prindle, 1906, p. 114). Scheelite has been found in concentrates 

(Byers, 1957, p. 188, 210), along with cassiterite (Joesting, 1942; ATDM Pamph. 1, p. 

10-11). Considerable stibnite float was found in old dredge tailings (Joesting, 1943, p. 9). 

 Mining was largely by open-cut methods in most years from 1903 to 1915. 

A dredge operated from 1926 or 1927 through 1934 (Cobb, 1976, p. 29). Gold production from 1903 to 1910 was over 17,700 ounces (Prindle and Katz, 1913, p. 112-113).

Workings/exploration:

 The prospect was staked as the Rex claim in 1911 by W.S. Reese who conducted a minor amount of exploration in that year (Times Publishing Company, 1912; Brooks, 1912). 

Legal problems prevented additional work and in 1912 no work was conducted (Smith, 

1913; B 525). By 1931, a 320-foot adit had been driven on the Rex shear zone (Hill, 

1933). This adit intersected a 4-inch-thick fault zone 20 feet from the portal and a 3-inch 

quartz-bearing shear 150 feet from the portal. A 3-foot-thick, northeast-striking shear 

was intersected 72 feet from the portal and had produced a few tons of ore averaging 

$8.50 per ton in gold (0.4 ounces of gold per ton) prior to 1931 (Pilgrim, 1932). The adit 

intersected a fault zone oriented N 60 E, 80 SE, about 230 feet from the portal. At the 

258-foot station of the tunnel, drifts had been driven on a N 60 E shear zone. The northeast drift had followed this shear for 45 feet and the southwest drift was extended 100 

feet. Free gold was recovered from a 3-inch-thick quartz stringer near the face of the 

northeast drift; the stringer had an east-west strike and a 45 S dip. Approximately 40 feet 

from the main adit, the southwest drift intersected a 3-inch-wide, N 75 E, 25 SE. quartz 

stringer which also contained free gold (Pilgrim, 1932; Stewart, 1933). W.S. Reese still 

owned the prospect in 1938 when a small amount of work was conducted in the main adit 

(Reed, 1939). 

Production notes:

 Prior to 1931, the shear zone had produced a small amount of ore that contained an average of $8.50 per ton in gold (0.4 ounces of gold per ton) (Pilgrim, 1932).

Geologic description:

 Mineralization on the Blue Moon Mazeppa prospect consists of at least three separate 

types of mineralization (Freeman, 1992). Gold-bearing quartz shear zones of the Blue 

Moon shaft consist of thin quartz-bearing shear zones (6 inches to 3 feet wide) that contain free gold, pyrite, arsenopyrite, stibnite and minor sphalerite; grades are up to 4 ounces 

of gold per ton (Prindle, 1910). A large proportion of the free gold is disseminated within 

pyrite and arsenopyrite grains. 

 Massive coarse-grained stibnite mineralization was also uncovered on the Blue Moon 

Mazeppa prospect. The stibnite lode uncovered was reported to be 8 feet wide and was 

exposed over 100 feet of strike length (J. Taylor, oral commun., 1986). 

 The third style of mineralization on the Blue Moon Mazeppa prospect is present only as 

float on a dump excavated during placer operations along Chatham Creek. Boulders of 

tabular gray to white marble contain coarse-grained cubic pyrite and blackjack sphalerite 

in grains up to a centimeter across and minor galena and boulangerite (Freeman, 1992).

Workings/exploration:

 The property was located as the Blue Bell lode in 1903 and development work began in 

1909 with a 24 foot shaft. This shaft was flooded with water seepage from Chatham 

Creek and was abandoned (Smith, 1913, B 525; Prindle, 1910). A second shaft was sunk 

approximately 100 feet upslope from the first shaft and reached a depth of 85 feet before 

it too was abandoned due to heavy water influx (Prindle, 1910). In 1912, approximately 

100 feet uphill from these shafts, the Blue Moon shaft was sunk to a depth of 60 feet. By 

December, 1912, the shaft had been sunk to a depth of 100 feet, 150 feet of drift had been 

driven and 5 stopes were opened for production. The eastern drift was longer than the 

western drift and only a small amount of water had been encountered in the workings 

(Smith, 1913; B 525). Over the period extending from November, 1912 through the middle of 1913, the Pioneer Mining Company mill treated approximately 200 tons of ore 

from the Blue Moon shaft (Chapin, 1914). The ore ran $50 to $100 per ton in free milling 

gold (2.4 to 4.8 ounces of gold per ton). 

 The Pioneer Quartz Mining Company mill consisted of a five-stamp Joshua Hendy mill 

utilizing 1000 pound stamps dropping at a rate of 100 times per minute. The rock was 

trammed from the mine 300 feet to the northwest where it was screened with undersize 

going directly to the feed bins and oversize going through a Joshua Hendy jaw crusher. 

Minus-40 pulp from the stamps fed onto 20 feet of amalgamation plate which fed an 

amalgam trap and a 6-foot-long riffle box (Chapin, 1914). Tailings from the mill contained $0.50 to $3.00 per ton in gold (0.02 to 0.1 ounces of gold per ton). Stamp sand 

concentrates were not saved. By the summer of 1913, the mill had closed and the Blue 

Moon shaft was inaccessible (Chapin, 1914). In 1914, the mill was dismantled and 

moved to the Hi Yu mine (Stewart, 1922). By 1931, the shaft house had been torn down 

and the prospect was idle (Hill, 1933). 

 In 1986, the Blue Moon shaft was marked by a 50 foot diameter depression centered on 

the shaft collar (Freeman, 1992). The upper 50 feet of overburden surrounding the shaft 

has been removed by placer operations (Freeman, 1992). 

Production notes:

 A one ton shipment of ore from the prospect on April 17, 1909 contained $50 per ton in 

gold (2.4 ounces of gold per ton) (Prindle, 1910). Prospecting on the prospect continued 

in 1910 but no production was recorded (Brooks, 1911). Several shipments of ore form 

the Blue Moon shaft were custom milled in Fairbanks and returned values ranging from 

$50 to $100 per ton in gold (2.4 to 4.8 ounces of gold per ton) (Times Publishing Company, 1912). Over the period extending from November, 1912 through the middle of 

1913 the Pioneer Mining Company mill treated approximately 200 tons of ore from the 

Blue Moon shaft (Chapin, 1914). The ore ran $50 to $100 per ton in free milling gold

that the Bobbie shear zone trends nearly north-south with a west dip and consists of 

banded galena with stibnite as the main components. Galena crystals near the wall rock 

grade into the center of the sulfide vein where coarse euhedral galena occurs. Brooks 

(1916, B 649) noted that stibnite occurred as kidney-shaped masses with euhedral quartz 

crystals; minor pyrite was embedded in the stibnite. The Bobbie prospect was examined 

as a possible source of antimony in 1942 but no additional exploration was conducted due 

to insufficient tonnage potential (Killeen and Mertie, 1951).

Geologic description:

 The discovery on the Mary claims was explored in 1931 and consisted of a N 70 W, 70 

SW shear zone which averaged 4 to 8 feet wide. The hanging wall consists of 1 to 6 feet 

of crushed quartz while the footwall is 1 to 2 feet of blue clay-rich gouge (Hill, 1933). 

Iron oxide staining was present on some quartz, and arsenopyrite, and argentiferous galena had been identified on the prospect. A sample collected by Hill (1933) across 5 feet 

at the bottom of a 15 foot shaft averaged $0.46 of gold per ton (0.02 ounces of gold per 

ton). The Anna prospect was one hundred feet south and uphill from the Mary but had 

not been exposed to any degree in 1931. By 1931, the shaft on the Mary prospect had 

been sunk to a depth of 25 feet but had caved when visited by Stewart (1933) and Pilgrim 

(1932). Dump samples contained galena, arsenopyrite and stibnite with moderate gold. 

No production records are available from this shaft. The prospect was purchased by 

George Warmbold in 1938 and several pits and trenches were dug in late 1938 in an attempt to trace the shear zone.

Geologic description:

 The Tamarack prospect was discovered by grid soil sampling by auger, initiated in 1997 

and completed in 1998 (Freeman and others, 1998). Gold values from 1998 soil sampling 

were up to 1,986 ppb, with arsenic values to 6,266 ppm, lead values to 9,536 ppm and 

bismuth values to 18.1 ppm. The strongest gold values were clustered around the old 

Colbert and Warmbold prospect (ARDF no. LG132) and the Anna Mary prospect (ARDF 

no. LG130) where northwest striking quartz veins had been mined prior to World War II. 

Lead values were particularly high over the old Bobbie prospect (ARDF no. LG129) 

where galena had been noted in old workings, however, gold values from 1998 soils in 

the Bobbie prospect area were low. Bismuth values are strongest along a 3,000-foot-long 

N-S trending zone through the Colbert and Warmbold prospect. As a follow-up to the 

gold-arsenic-bismuth anomalies discovered in soils, fourteen reverse circulation drill 

holes totalling 4,747 feet, were completed in the Tamarack area in 1998. These were the 

first drill holes of any kind to be drilled on the Tamarack prospect. Initial drilling consisted of seven vertical holes with follow-up drilling consisting of seven angle holes intended to intercept a combination of structures and areas of interest found during vertical 

drilling. Eight of the fourteen holes drilled on the prospect encountered significant gold 

mineralization and all of the holes returned anomalous gold and gold-pathfinder elements.

 Bedrock is schist and the gravel is largely quartzite, igneous rocks and vein quartz. 

Depth to bedrock (measured on 5 claims) was from 75 to 125 feet (Prindle and Katz,

mouths of Dome and Vault Creeks. Placers are about 65 to 200 feet deep at the mouths 

of Dome and Vault Creeks (Mulligan, 1974, p. 11). From 1911 to 1927 all mining was 

from drift mines, and dredging began near the mouth of Cleary Creek in 1928. USSR&M 

dredge no. 3 worked on the Chatanika from 1928 to 1942, and from 1946 to 1963 (R.M.

Geologic description:

 Cleary Creek is a highly productive placer gold creek that has been mined over its entire 

length of over 5 miles. Gold production began as early as 1903 and production continues 

today from fresh placer cuts near the mouth of Chatham Creek. 

 In the early 1900's, reports about Cleary Creek describe the depth to bedrock schist as 

being from 14 to more than 135 feet (Prindle and Katz, 1913, p. 107). Gravel is a variety 

of schist, some hornblende-garnet rock and boulders of vein quartz. These early reports 

also describe the gold occurring in the basal 1 to 7 feet of gravel and the top 1.5 to 4 feet 

of bedrock, with a paystreak of 35 to 150 feet wide; the average value of the paystreak 

was 0.566 ounces of gold per cubic yard (Prindle, 1905). Concentrates contained gold, 

stibnite, cassiterite, scheelite, pyrite, garnet, and rutile (Prindle, 1905). 

 From 1903 through 1924 production was about 1,129,650 fine ounces (Cobb, 1976; 

OFR 76-633). The largest nugget reported weighed 13.51 ounces. Most production was 

from drift mines working a pay streak 150 feet wide with an average thickness of 5 feet. 

In 1915, most mining in the Chatanika flats was on benches on the south side of the Chatanika valley (Eakin, 1915). U.S.S.R. & M. Dredge no. 3 worked on lower Cleary Creek 

and near Chatanika from 1928 to 1942 and from 1946 to 1963. Dredge no. 5 worked on 

upper Cleary Creek from 1929 to 1942 (R.M. Chapman, 1978, U.S.G.S. memorandum).

In 1996 and 1997, Alf Hopen leased placer ground from the Alaska Gold Co. on Upper 

Cleary Creek (Swainbank and others, 1997). In 1999, fresh placer cuts on Cleary Creek 

were observed at the mouth of Chatham Creek (J. Schaefer, field observation, 1999).

(Freeman and others, 1998). This regional structure also controls mineralization on the 

Dolphin prospect (ARDF no. LG112) and Cleary Hill mine (ARDF no. LG119) to the 

southwest. At this prospect, the structure juxtaposes lower plate rocks of the Fairbanks 

Schist on the southeast with upper plate rocks of the Chatanika terrane on the northwest. 

Three holes were drilled in the Wolf Creek area. While all of them had anomalous gold

 By 1912, two areas of low grade gold mineralization were exposed (Times Publishing 

Company, 1912). One area consisted of a 3- to 6-inch-wide, iron-oxide-cemented breccia 

exposed in a short tunnel. Small amounts of free gold could be panned from this material 

(Smith, 1913; B 525). This mineralization is flat-lying and appeared to be a capping 

rather than a shear zone. The second occurrence on the Sky High prospect is 14 feet wide 

and is accessed by a 15 foot deep shaft. The gold content of this occurrence was not considered to be of commercial grade in 1912 (Smith, 1913; B 525).

that this ore averaged $40 per ton gold (1.9 ounces of gold per ton). Several northeast 

trending shear zones were exposed on the Foster Hungerford prospect in 1931. A N 50-

60 E trending stringer approximately 8 to 10 inches wide was exposed in a 10 foot deep 

shaft on the Alaska #2 claim (Hill, 1933). This shear zone assayed $16.88 per ton in gold

Geologic description:

 The Alaska prospect originally was known by the name Jupiter Mars prospect after several claims and fractions bearing that name. The prospect was discovered prior to 1910 

by which time the Jupiter Mars claim was being explored by a 70-foot adit and a 50-foot 

crosscut (Brooks, 1911). Work continued in 1911 and by 1912, seven or eight claims in 

the area had been purchased by the Jupiter-Mars Consolidated Gold Company (Brooks, 

1912; Smith, 1913; B 525). This company owned the Shamrock, Emerald, Gladstone, 

Richman, Henchman, Chatham, Jupiter, Mars, and Jupiter Mars Extensions Nos. 1, 2, 3 

and 4 (Times Publishing Company, 1912). Work was concentrated in two short adits on 

the Goldstone claim. These adits intersected a northwest-striking, shallowly southdipping shear zone from which several tons of custom milled ore returned values of about 

$30 per ton (1.45 ounces of gold per ton) (Smith, 1913; B 525, p. 175). Sulfides make up 

only a small proportion of the shear zone. Gold is associated with white-quartz vein material (Smith, 1913; B 525, p 175). The shear zone is cut off in the northern tunnel by frozen fluvial gravels indicating the material in which the tunnel is driven may be part of 

large slump block. A 66-foot deep shaft had been sunk to the east of the adits by 1912 to 

prospect along the shear zone (Smith, 1913; B 525). Work continued in 1913 when the 

shaft was deepened to 125 feet and 112 feet of drift were driven from the shaft (Chapin, 

1914, p. 337). 

 The area was restaked as the Alaska, Alaska #2 and Alaska #3 claims by Fred M.

Wackwitz on July 1, 1931 (Hill, 1933). The prospect subsequently became known as the 

Alaska group and was first prospected with large ditches cut by ground sluicing to remove 

surface debris. A scorodite-stained quartz-bearing shear zone oriented east-west with a 30 

degree north dip, was exposed in this manner; it measured 3 to 5 feet wide and averaged 

$0.43 per ton (0.02 ounces of gold per ton). 

 In 1979, Placid Oil began surface trenching, diamond core drilling and geochemical 

sampling of the shear zones which had been discovered previously. Between 1979 and 

1986, Placid Oil drilled 5,137 feet of diamond core and cut several thousand feet of dozer 

trenches on the prospect, primarily on the Christina shear zone north of the adits and shaft 

previously driven on the prospect (Porterfield and Croff, 1986). 

 In 1986, Placid Oil Company dropped its lease on the prospect. The trenches on the 

Alaska prospect were reclaimed by Placid Oil in 1985; however, sidewall exposures of 

gold quartz and sulfide shear zones remain and served as sample sites for field work conducted by Fairbanks Exploration Inc. in 1987. Samples collected from the prospect contained anomalous gold (70 to 1600 ppb), silver (5.5 ppm to 179.9 ounces of silver per 

ton), arsenic (+1000 ppm) and antimony (330 to +10000 ppm) hosted in white quartz and 

quartz-sericite, rhyolite tuff, stained by scorodite, iron oxide and antimony oxide 

(Fairbanks Exploration Inc., unpublished report, 1987). The core of the Jupiter Mars 

shear zone was exposed in trench walls where it contained 1 to 6 inch wide quartz stringers which were broken and recemented by later quartz. The shear strikes N 80 E and dips 

55 SE. Host rocks in the trench exposures and on the dumps of one of the old adits were 

highly oxidized rhyolitic tuff with pervasive scorodite and iron-oxide stains. No other 

work has been conducted on the Alaska prospect and all underground workings are now 

inaccessible.

 A 70-foot adit tunnel and a 50-foot crosscut were completed in 1910 on the JupiterMars property (Brooks, 1911, p. 34). Two tunnels were dug on a flat-lying vein that dips 

south and shaft was sunk 125 feet to a vein (Chapin, 1914, p. 337). All of the old workings caved by 1931, and newer workings consisted mainly of trenches and pits (Hill, 

1933, p. 99-100).

Geologic description:

 Gold occurs in a shear zone oriented N 70 W, dipping 50 S; it is composed of quartz 

stringers in a soft schist (Times Publishing Company, 1912; Brooks, 1916; B 649). The 

dip of the shear flattens with depth and early quartz is cemented by later stibnite, pyrite 

and arsenopyrite (Smith, 1913; B 525, p. 171). The hanging wall contact is a fault plane 

in the Quemboe shaft. Samples collected by the owners in 1912 assayed $22.50 to $32 of 

gold per ton, or about 1 to 1.5 ounces of gold per ton (Smith, 1913; B 525). An unspecified quantity of ore which was custom milled in Fairbanks averaged $35 of gold per ton 

(1.7 ounces of gold per ton) (Times Publishing Company, 1912). The prospect was examined in 1942 as a possible source of antimony, however, the low grade and restricted 

distribution of antimony did not warrant additional exploration (Killeen and Mertie, 

1951). No other published or private references to the Quemboe prospect are known.

 Mineralization consists of stibnite filling open fractures and a small proportion of sulfides (Smith, 1913; B 525). Minor amounts of jamesonite, arsenopyrite, pyrite and zinkenite(?) also were identified (Chapman and Foster, 1969). By 1912, a 60-foot-deep shaft 

had been sunk and 120 feet of drift had been driven at the 60-foot-level. Stoping of ore 

began in December, 1912. A 6- to 30-inch wide brecciated and quartz-cemented shear 

zone in the shaft trends N 70 E and dips 45 S (Times Publishing Company, 1912, p. 64). 

Assays from the development muck ranged from $28 to $130 per ton in gold (1.3 to 6.3 

ounces of gold per ton) and average $30 per ton (1.4 ounces of gold per ton). 

 Cobb (1976, p. 80) noted that Grace E #1 is probably the same ground as Harris and 

Brown or Sky High. Forbes and others (1968) reported that the Grace E #1 prospect 

opened two small quartz veins that carry 2%-3% sulfides (including arsenopyrite and minor pyrite) and free-milling gold. An unaltered schist 9 feet into the hanging wall assayed 

1.3 ppm gold.

Geologic description:

 In the 1950's through the 1970's, almost 20,000 ounces of gold was mined from surface 

and underground workings on the Christina prospect. Exploration continued throughout 

the 1980's, when several holes were drilled to explore the extent of mineralization in the 

Christina system. Based on the drilling conducted in the 1980's, reserves have been estimated at over 68,000 ounces of gold. 

 The following geologic description is based on mapping conducted by Fairbanks Exploration Inc. (unpublished report, 1988): The Christina prospect consists of a N 70-80 W, 

75 S shear zone. The Christina shear separates Cleary sequence rocks to the north from 

Fairbanks Schist to the south. The Cleary sequence forms the footwall and consists of interbedded rhyolite metatuff, laminated graphitic quartzite, black graphitic schist and chloritic calc-schist. The hanging wall is composed of biotite-quartz-mica schist, and micaceous quartzite. Both the hanging wall and foot wall are gently folded into east-west 

trending open folds whose axes plunge 10 to 20 degrees to the west. Amplitudes of the 

open folds range from 4 to 8 feet and wavelengths range from approximately 10 to 40 

feet. 

 On an outcrop scale, the Christina structure contains a series of parallel quartz veinlets 

which pinch and swell and form a sinuous outcrop pattern along strike. For example, the 

Christina shear on the west end consists of two discrete, quartz-rich zones with a total 

thickness of approximately 2 feet. Within 60 feet of strike length to the east, the quartzLG146 
Alaska Resource Data File 

Page 319 

rich zones merge and pinch down to a thickness of a few inches. In general, the Christina 

shear contains less massive quartz and more stockwork quartz to the east. 

 Hypogene and supergene alteration of the shear and adjacent wallrock has produced 

reddish hematite after pyrite, greenish scorodite after arsenopyrite, and yellow to white 

antimony oxides after stibnite, jamesonite and boulangerite. Sulfide and oxide alteration 

typically form envelopes paralleling the shear. Alteration in the footwall reaches at least 

40 feet from the shear in the lower sample area near the Vetter shaft while alteration in 

the hanging wall is minor. Scorodite and hematite alteration were most prevalent in the 

western portion of sample area. Antimony oxide alteration becomes pervasive in the central portion of the vein where quartz-free pods of massive, striated stibnite occur. 

 In 1981, Placid Oil Company completed 4661 feet of diamond drilling in 16 holes on 

the Christina and Orange Free shear zones. The Orange Free shear zone has a northeast 

strike nearly perpendicular to the Christina shear zone. In 1985, Placid Oil utilized reverse circulation rotary drilling techniques to complete 4623 feet of drilling in 18 holes on 

the Christina shear zone. At a 5-foot mining width, the Christina system had drill indicated reserves of 39,600 tons grading 0.660 ounces of gold per ton and 1.74 ounces of silver per ton in one block; another block containing 73,900 tons grading 0.370 ounces of 

gold per ton and 0.71 ounces of silver per ton. The Spirit shear zone, located in the hanging wall of the Christina shear zone, contained an estimated reserve of 36,900 tons grading 0.411 ounces of gold per ton and 0.40 ounces of silver per ton over a five-foot mining 

width (Porterfield and Croff, 1986). The average grade of the Christina shear zone was 

0.551 ounces of gold per ton and 0.61 ounces of silver per ton while the Orange Free 

shear zone averaged 0.167 ounces of gold per ton and 15.4 ounces of silver per ton 

(Bentzen, 1982). 

Alteration:

 Hypogene and supergene alteration of the shear and adjacent wallrock has produced 

reddish hematite after pyrite, greenish scorodite after arsenopyrite, and yellow to white 

antimony oxides after stibnite, jamesonite and boulangerite. Sulfide and oxide alteration 

typically form envelopes paralleling the shear. Alteration in the footwall reaches at least 

40 feet from the shear near the Vetter shaft while alteration in the hanging wall is minor. 

Scorodite and hematite alteration were most prevalent in the western portion of the deposit. Antimony oxide alteration becomes pervasive in the central portion where quartzfree pods of massive, striated stibnite occur (Fairbanks Exploration Inc., unpublished report, 1988).

Workings/exploration:

 Mineralization on the Kawalita claim, which adjoins the Christina prospect to the south 

and east, was discovered in 1908 (Smith, 1913; B 525). Between 1961 and 1963, Ed Ebbert sank an inclined shaft to a depth of 50 feet on the western end of the Kawalita claim. 

In 1963, this shaft was deepened to 147 feet and the haulage levels moved into the footwall to better control the heavy ground and water (Warfield, 1970). The underground 

portion of the mine was closed in 1965, but surface mining on the Kawalita claim continued through 1966. 

 In late 1977, Tri-Con Mining and Mohawk Oil Company extracted shear zone material 

from surface cuts on the Christina claim over a strike length of 450 feet to a depth of 15 

feet. In early 1978, Placid Oil Company leased the Christina prospect and began an extensive exploration and development program. Geological mapping, VLF and magnetics 

geophysical surveys, and soil and rock geochemical sampling surveys were followed up 

in 1978 with dozer trenching and completion of 5174 feet of diamond core drilling in 23 

holes. Approximately 2314 feet of diamond core drilling in nine holes as well as extensive soil grid geochemical surveys were completed in 1980 on the Christina shear zone 

system. In 1981, approximately 1489 feet of trackless underground drifting was driven to 

and on the Christina shear zone system. The Christina adit was constructed at a design 

size of 8 feet by 8 feet, however, timbering in some areas reduced the finished dimensions 

of the workings. During construction of the adit a previously undiscovered shear zone, 

the Orange Free shear zone, was intersected approximately 300 feet from the portal. In 

addition to the underground workings, Placid Oil completed 4661 feet of diamond drilling 

in 16 holes on the Christina and Orange Free shear zone. 

 Activities on the Christina in 1982 consisted of 13,045 feet of diamond core drilling in 

25 holes designed to test the down-dip extension of the Christina system. In addition, 600 

pound bulk samples were collected by Placid Oil Company from the Christina shear zone 

and the Orange Free shear zone where these shears were exposed in underground workings (Bentzen, 1982). Activities on the Christina prospect in 1983 consisted of 8512 feet 

of diamond core drilling in 23 holes to further outline ore shoots on the Christina shear 

zone (Porterfield and Croff, 1986). In 1985 Placid Oil utilized reverse circulation rotary 

drilling techniques to complete 4623 feet of drilling in 18 holes on the Christina shear 

zone. In 1986, Fairbanks Exploration Inc. conducted preliminary grab sampling of the 

Christina adit and Nordale adit dumps (Fairbanks Exploration Inc., unpublished report, 

1986). 

 During July, 1988, Fairbanks Exploration Inc. extracted a bulk sample from a high 

grade portion of the Christina shear zone in the same area as the 1986 bulk sample and 

the Mohawk open cut. Initial work on the program entailed stripping overburden to prepare a 12 foot wide pad along the length of the shear zone. Ore was extracted with a 

backhoe by digging a trough approximately 3 feet wide and 3 feet deep. After each threefoot lift was mined, the footwall and hangingwall were stripped to expose the next lower 

bench for mining. Two separate areas on the Christina prospect were mined to obtain the 

1988 bulk sample. Most of the tonnage (approximately 85%) was excavated from the upper sample area; the remaining 15% of the ore was extracted from the lower sample area. 

 During the summer and fall of 1990, Polar Mining conducted bulk sampling of the 

Christina shear zone near the Kawalita shaft. Unlike the Christina shear in the 1988 bulk 

LG146 
Alaska Resource Data File 

Page 321 

sample area, the Polar Mining sample area contains mineralization in both the foot wall 

and hanging wall of the Christina shear. Polar Mining exposed this shear zone for approximately 500 strike feet. Approximately 1,000 to 1,200 tons of material were extracted from this area and treated in a one stage wet jig. This method of sampling proved 

unsatisfactory since tailings ponds averaged 0.14 ounces of gold per ton (P. Metz, oral 

commun., 1991) while the recovered grades averaged 0.030 to 0.033 ounces of gold per 

ton (D. May, oral commun., 1990). 

Production notes:

 Between 1957 and 1961, approximately 4900 troy ounces of gold was extracted from 

500 feet of surface strike on the Kawalita claim (R. Vetter, oral commun., 1991; Saunders, 1960, ATDM MR 49-4). The shear zone material averaged one troy ounce per ton 

(Brown, 1962; R. Vetter, 1986, oral commun.). Between 1961 and 1966, an estimated 

10,000 ounces of gold was extracted from surface and underground workings on the 

Christina prospect on the Kawalita claim (R. Vetter, oral commun.1986). In 1963 and 

1964, Scott Haskins extracted 962 troy ounces of gold from shear zone material which averaged 1.96 ounces per ton over 350 feet of strike to a depth of 10 feet (S. Haskins, 1986, 

oral commun.). Mr. Haskins also sunk a 90 foot shaft on the shear zone but production 

from this shaft was insignificant. In 1967 and 1968 approximately 250 troy ounces of 

gold was extracted from a 35-foot-deep shaft and 110 feet of surface workings (R. Vetter, 

oral commun., 1986). In late 1977, Tri-Con Mining and Mohawk Oil Company leased 

the Christina claim and extracted shear zone material from surface cuts over a strike 

length of 450 feet to a depth of 15 feet. Material from this open cut averaged approximately 3 troy ounces of gold per ton (R. Vetter, oral commun., 1986). Total production 

by Tri-Con-Mohawk is estimated at 3375 troy ounces of gold. 

Reserves:

 At a 5-foot mining width, the Christina system has drill-indicated reserves of 39,600 

tons with 0.660 ounces of gold per ton and 1.74 ounces of silver per ton in one block, and 

73,900 tons with 0.370 ounces of gold per ton and 0.71 ounces of silver per ton in an adjacent block. The Spirit shear zone, located in the hanging wall of the Christina shear 

zone, contains an estimated reserve of 36,900 tons with 0.411 ounces of gold per ton and 

0.40 ounces of silver per ton over a five-foot mining width (Porterfield and Croff, 1986).

Geologic description:

 The prospect was located in 1908 when Fred Fey discovered a large quartz boulder with 

visible gold (Times Publishing Company, 1912). About 150 feet below this discovery, an 

adit revealed a shear zone striking N 60 W and dipping 65 to 80 S. The shear exhibits 

prominent slickensides showing nearly horizontal strike-slip motion (Smith, 1913; B 

525). Average ore width in the stopes was 14 inches (Times Publishing Company, 1912). 

 A stibnite-bearing shear zone striking east and dipping south cuts the Chatham shear in 

the southeast drift about 150 feet from the main adit (Brooks, 1914). The stibnite occurs 

in massive, lenticular pods oriented diagonally to the strike of the shear zone. The shear 

zone is 10 to 15 feet wide and was traced on the surface for over 500 feet. Individual 

pods range from a few inches to several feet in width and are 10 to 12 feet in length. In a 

raise 825 feet from the portal, the stibnite is along a N 70 E, vertically-dipping shear zone 

with about 18 inches of pure stibnite in a clay-rich gouge zone (Brooks, 1918). 

 This mine produced both gold and anitmony ore. Ore from the Chatham mine was estimated to contain $30 to $40 per ton in gold (1.45 to 1.93 ounces of gold per ton) (Times 

Publishing Company, 1912). Workings consisted of the main 1300 foot Chatham adit 

and a Lower adit which was collared 120 feet below the Chatham adit. 

 The Chatham mine area was examined by Fairbanks Exploration Inc. in 1986 and preliminary sampling conducted (Fairbanks Exploration Inc., unpublished report, 1986). A 

sample taken from a small pit near the head of Chatham Creek contained 1800 ppb gold, 

LG147

with anomalous silver, arsenic and antimony. The sample consisted of scorodite and 

stibiconite in stained carbonaceous quartzite with no visible sufides. Visible gold was 

found in the pit from which this sample was extracted.

Workings/exploration:

 By mid-1916, the main Chatham adit had been driven 1,300 feet (Brooks, 1918). Approximately 400 feet of the shear zone had been stoped from the drift level to the surface; 

the workings extended from a point 175 feet northwest of the main adit to a point 225 feet 

southeast of it (Brooks, 1914). A second adit was collared 120 feet below the Chatham 

adit. 

Production notes:

 On August 12, 1912, a 12-ton-per-day two-stamp Joshua Hendy mill began treating the 

Chatham mine gold ore (Times Publishing Company, 1912). Approximately 100 tons of 

stibnite was mined from a four-foot-thick pod in the east drift (Stewart, 1915). Total 

amount of gold and antimony ore production is not known.

 The Bellows Creek prospect was discovered by Roudolph Vetter and Mike Marley in 

June 1983. During that year, a dozer trench excavated on a geochemical anomaly exposed a shear zone containing free gold, stibnite, arsenopyrite, and fine grained boulangerite and jamesonite. The mineralization is hosted by quartz mica schist and quartzite of 

the Fairbanks Schist. The shear zone is approximately 2 feet wide, trends east-west and 

dips 45 N (R. Vetter, oral commun., 1992). Assays showed gold grades up to 0.5 ounces 

of gold per ton.

Geologic description:

 The McCarty vein varies from a few inches to five feet wide at this location. The vein 

strikes N 70 W and dips 65 SW. It has been traced for 1200 feet and ore from the surface 

pits along the full extent of this distance has been found to carry gold. There has been 

considerable shearing along the vein walls and several small faults have been encountered. The vein filling is a milky quartz but often contains impregnations of arsenopyrite 

(W.J. McCarty, unpublished report, 1932). 

 By 1930, the McCarty shaft was 60 feet deep along the south dipping McCarty shear 

zone (Stewart, 1931). A drift from the 60-foot level of the shaft extended 135 feet east 

and 369 feet west. Two raises had been driven to the surface from the 60-foot level, one 

at the 135-foot station in the east drift and one at the 284-foot station of the west drift. 

All mill grade ore had been stoped from above the 60-foot level and the shaft was being 

deepened to the 200-foot level in 1930. Stoping from the 60-foot level produced a little 

over 1200 tons of ore. This ore was milled at the McCarty mine downslope from the 

McCarty shaft. Shaft sinking at the McCarty shaft continued in 1932 with the intent to 

deepen the shaft from 80 to 150 feet and drive production drifts at that level (Pilgrim, 

1933).

Geologic description:

 Prior to 1969, the divide between Fairbanks and Wolf Creeks was host to several producing mines and numerous prospects. The mineralization sought in all of these mines 

and prospects was high grade gold mineralization hosted by large northwest and northeast 

trending shear zones. Low grade mineralization was known to be present at the McCarty 

(ARDF no. LG152), Pioneer (ARDF no. LG155) and Pennsylvania (ARDF no. LG156) 

mines, along the margins of higher grade portions of the shear zones. However, these 

lower grade zones could not be profitably worked using the existing technology (W. 

McCarty, oral commun., 1988). In 1969, International Minerals and Chemicals (IMC) began an exploration program designed to address the possibility of surface mining the 

lower grade material in this area. IMC conducted trenching and rotary drilling targeted at 

low grade, zones adjacent to previously mined high grade shear zones. These activities 

resulted in discovery of the Saddle prospect (Pilkington, 1970). 

 IMC's initial exploration efforts on the Saddle prospect consisted of geological mapping 

and sampling of four, previously excavated trenches and open cuts. IMC also excavated 5 

new dozer trenches totalling 4,299 feet. Initial sampling was conducted in three trenches 

previously excavated by Keystone Mines Inc. One of these trenches was located in the 

footwall of the Pennsylvania shear zone, approximately 1,300 feet northeast of the Pioneer shaft . This trench exposed a schist-hosted quartz-bearing shear zone oriented N 35 

E, 65 NW. One-foot channel samples collected in the hanging wall of this shear included 

9 feet that assayed 0.9 ppm gold (0.029 ounces of gold per ton) and 58.3 ppm silver (1.70 

LG151

Page 332 

ounces of silver per ton). The rocks consisted of iron-, arsenic- and antimony-oxidestained silver-gray schist. 

 IMC also sampled two dozer trenches previously excavated by Keystone Mines approximately 500 feet west of the Pioneer shaft. These two dozer trenches cut the Pioneer 

shear zone which trends N 70 W and dips 50 S. The first trench had 17 feet that assayed 

0.54 ppm gold (0.016 ounces of gold per ton) and 75.6 ppm silver (2.20 ounces of silver 

per ton); the rocks in the trench consisted of brecciated and silicified quartz-mica schist 

containing minor iron- and antimony-oxide staining. The second trench had 25 feet that 

assayed 5.68 ppm gold (0.166 ounces of gold per ton) and 142.6 ppm silver (4.16 ounces 

of silver per ton) in silicified and brecciated quartz-mica schist with weak iron-oxide 

staining. 

 In order to test the down-dip extent of suspected northeast-trending mineralization 

picked up in trenches on the Saddle prospect, IMC conducted rotary drilling using a 5-

inch rotary drilling rig (Pilkington, 1970). Two vertical rotary holes totalling 485 feet 

were drilled on the Saddle prospect. 

 Based on the results from trenching and drilling, IMC calculated drill inferred reserves 

of 2,111,000 tons grading 0.037 ounces of gold per ton and 0.46 ounces of silver per ton 

in the Saddle Zone (Pilkington, 1970). These reserves were considered subeconomic at 

then-current gold and silver prices and IMC terminated its lease with Keystone Mines Inc. 

in 1970.

 In 1987, Keystone Mines leased their holdings to Fairbanks Exploration Inc. and in

conducted drilling designed to confirm and expand on the results previously generated by

Geologic description:

 The McCarty mine milled ore from the Henry Ford group of claims which included ore 

from both the McCarty vein (ARDF no. LG150), the Henry Ford vein (ARDF no. LG153) 

and the American Eagle vein, which is located closest to the mill. This mine is located at 

the head of Fairbanks Creek and has been one of the largest lode-gold producers in the 

Fairbanks Creek area, second only to the Hi-Yu mine (ARDF no. LG182). 

 Country rock in the area is generally quartz-mica schist, but quartzite schist and calcareous schist are also present. Sericitization is said to characterize the wall rock near the 

vein (Joesting, 1941). 

 Most ore milled came from the nearby American Eagle vein, which is from one to three 

feet thick, strikes N 60 W, dips 55 to 60 SW; it consists of coarsely crystalline quartz with 

free gold and small proportions of jamesonite, stibnite, arsenopyrite and sphalerite 

(Joesting, 1941, p. 3). Occasional large kidneys of high-grade stibnite, with up to 60.66% 

antimony, are associated with the vein (Joesting, 1941, p. 3). The McCarty group of veins 

at the head of Fairbanks creek were mined sporadically from 1911 to 1917 and almost 

continously from 1927 to 1942, with production estimates ranging from 26,800 ounces 

from 16,750 tons of ore grading 1.6 ounces of gold per ton (Porterfield and Croff, 1986), 

to an estimated 60,000 ounces of gold (Metz and others ,1987). 

 There is no record of work on the property from 1942 until 1984, when Placid Oil Company drilled 6,137 feet in 23 diamond core holes. Preliminary ore reserves from this work 

LG152

were calculated at 15,000 tons grading 0.80 ounces of gold per ton. 

 In 1987 and 1988, Fairbanks Exploration, Inc. conducted geochemical sampling of 

stamp sand tailings and waste dumps of the McCarty mine. Stamp sands yielded gold 

values of 0.314 and 1.028 ounces of gold per ton with highly anomalous silver, antimony 

and arsenic (Fairbanks Exploration Inc., unpublished report, 1986). Geochemical samples collected during the 1987 field program were designed to test the precious metal content of the McCarty mine tailings dumps. This site contains stamp sands with interbeds 

of sulfide rich material in which fine gold occurs in its native form and as inclusions in 

arsenopyrite and pyrite. The McCarty mine tailings ponds exhibit distinct sulfide and 

gold rich lenses from 1 to 4 inches thick separated by 1 to 2 feet of virtually clean quartz 

sand. The average gold grades from the McCarty mine waste dumps range from 0.132 to 

0.158 ounces of gold per ton (Fairbanks Exploration Inc., unpublished report, 1988).

Workings/exploration:

 The McCarty mine, also known as the American Eagle mine, was one of the most productive gold mines in the district. The American Eagle shear zone was accessed through 

the American Eagle adit and American Eagle shaft. Although the old stamp mill and 

head-frame of the American Eagle shaft are still standing, the underground workings of 

the mine are inaccessible (Freeman, 1992). During the winter of 1914-1915, a 450 foot 

adit was driven on the American Eagle claim and significant amounts of ore were extracted during the summer of 1915 (Stewart, 1915). The American Eagle shaft had been 

sunk to a depth of 107 feet by 1915 (Brooks, 1915). 

 In 1936, United States Smelting Refining and Mining Company (USSR&M) began 

drifting along the 135-foot level through the American Eagle shaft (Smith, 1939; B 910). 

Extensive development continued in 1938 but the results of bulk sampling were not encouraging (Smith, 1939; B 917). USSR&M sank 120 feet of shaft in the American Eagle 

shaft, put in 625 feet of raise and drove 1,816 feet of drift, cross-cuts and adit in 1938 

(Reed, 1939). Mining continued in 1939 when USSR&M completed 465 feet of drifts 

and crosscuts and nearly 400 feet of raising. The ore was treated in a 2 stamp Nissen mill 

and the tailings were impounded for later up-grading (Smith, 1941). Mining continued in 

1940 during which 639 feet of drifts and crosscuts were driven as well as 545 feet of 

LG152

Page 336 

raises. The American Eagle shaft was deepened to 250 feet giving access to over a mile 

of drifts and 1,750 feet of raises on the 28, 135 and 235 foot levels (Smith, 1942). Mining continued in 1941 when USSR&M sank a 65 foot winze from the east end of the 235 

level. USSR&M maintained the properties until 1958 but no further mining was reported 

from the mine (Porterfield and Croff, 1986). 

 In 1984, Placid Oil Company drilled 6,137 feet in 23 diamond core holes. During this 

period Alaska Mineral Services constructed a small carbon-in-pulp leach plant (the Haskins mill) at the McCarty mine site to treat stamp mill sands from the McCarty mine and 

the Hi Yu mine. The open pits, mine waste dumps and stamp sand tailings of the 

McCarty mine were examined and sampled in 1986 (Fairbanks Exploration Inc., unpublished report, 1986). 

Production notes:

 Total production from the American Eagle shear through 1917 was approximately 967 

ounces of gold with an average grade of about one ounce of gold per ton (J. McCarty, unpublished report, 1932). Milling of development material in 1929 and 1930 produced 

1,274 ounces of gold from 1,225 tons of ore averaging 1.04 ounces of gold per ton (J. 

McCarty, unpublished report, 1932; Hill, 1931). During 1931, approximately 34 ounces 

of gold averaging 1.25 ounces of gold per ton was recovered from 27 tons of material excavated from a surface cut on the American Eagle shear zone (J. McCarty, unpublished 

report, 1932). Smith (1933; B 844) reported that the McCarty mine was the largest producer in the Fairbanks Creek basin in 1931. A total of 600 tons of ore from the American 

Eagle workings was milled in 1938 at a rate of 240 tons per month (Reed, 1939). 

 The McCarty mine ceased operations in 1942 due to War Production Board Limitation 

Order L208. However, about 15 tons of high grade stibnite ore was shipped from the 

prospect in 1942. This ore graded 60.66% antimony (Joesting, 1942; ATDM Pamph. 1). 

In addition, about 5 tons of stibnite ore grading 45% antimony was also shipped from the 

American Eagle mine in 1942 (Joesting, 1943; Killeen and Mertie, 1943). 

 Total production from the McCarty mine workings (American Eagle, Henry Ford and 

McCarty shear zones) is estimated at 26,800 ounces from 16,750 tons of ore grading 1.6 

ounces of gold per ton (Porterfield and Croff, 1986). However, Metz and others (1987) 

estimate production from the McCarty mine was approximately 60,000 ounces of gold. 

Reserves:

 In 1984 Placid Oil Company drilled 6,137 feet in 23 diamond core holes. Preliminary 

ore reserves from this work were calculated at 15,000 tons grading 0.80 ounces of gold 

per ton. 

 In 1988, Fairbanks Exploration Inc. conducted bulk sampling of the American Eagle 

mine tailings and waste dump. Based on the results of this sampling, ore grade and tonnage estimates were calculated. These reserve estimates do not reflect mining conducted 

by Tri-Con Mining after mid-August 1988. The average gold grades from the American 

Eagle mine tailings range from 0.091 to 0.168 ounces of gold per ton. However, a portion 

of the samples were taken from stamp sands which had been re-treated in a cyanide mill 

erected on the prospect for this purpose in the early 1980's. Therefore, composite sample 

results are not an accurate estimate of gold grades for the bulk of the American Eagle 

mine stamp sands. Channel sampling of American Eagle mine tailings conducted in 1987 

LG152 
Alaska Resource Data File 

Page 337 

indicated average grades of 0.123 ounces of gold per ton and 0.74 ounces of silver per ton 

(Fairbanks Exploration Inc., unpublished report, 1987). Estimated tonnage of stamp 

sands at the American Eagle mine is 3,000 tons. The average gold grades from the 

American Eagle mine waste dumps range from 0.132 to 0.158 ounces of gold per ton 

(Fairbanks Exploration Inc., unpublished report, 1988).

Geologic description:

 Gold is found in quartz-rich portions of a shear zone. The lode was sampled and 

mapped in 1968 and indicated extremely high gold, silver, lead, antimony, arsenic and tin 

values (Forbes and others, 1968). Quartz veins and wall rock in old prospect trenches 

carry as much as 2.87 ppm Au (Pilkington and others, 1969, p. 11). Veins that strike N 

70 W, dip 55 S, and veins that strike N 65 E, dip 70 S. Altered schist as much as 1 foot 

into the footwall of the latter vein carries significant gold. Grab samples from veins contained betweeen 0.05 and 2.87 ppm Au (Pilkington and others, 1969). In 1969, the Ebberts prospect was sampled by International Minerals and Chemicals (IMC) in the vicinity 

of the main shaft. At this point, the shear zone trends N 85 W and dips 60 S and consists 

of narrow quartz stockwork zones on the hanging wall and foot wall, separated by altered 

schist. Stibnite and jamesonite occur on the hanging wall as kidney shaped masses. The 

mineralized zone was 13 feet wide and averaged 0.06 ounces of gold per ton and 8.4 

ounces of silver per ton (Pilkington, 1970). IMC also excavated a dozer trench which 

crossed the Ebberts shear 200 feet east of the Ebberts shaft. The trench exposure assayed 

0.046 ounces of gold per ton and 0.32 ounces of silver per ton over 25 feet.

Workings/exploration:

 The first activity was by Hugh M. Hinton who conducted hand trenching on the prospect (Saunders, 1960; ATDM MR 49-4). The prospect remained inactive until dozer 

trenching was conducted by United States Smelting Refining and Mining (USSR&M) 

sometime around 1950. Initial exploration examined the prospect's potential for antimony. In June 1960, Arctic Alaska Fisheries and Enterprises Inc. conducted dozer 

trenching on the prospect and exposed the Ebberts shear zone which was referred to as the 

Jamesonite shear zone (Saunders, 1960; ATDM MR 49-4). The Ebbert prospect was 

mined for antimony via a shallow shaft and open cuts from 1961 through 1964 by Ed Ebbert (R. Vetter, oral commun., 1986). The prospect was idle until 1967 when Ed Ebbert 

re-opened the shaft and open cuts after finding higher gold values in quartz-rich portions 

of the shear zone (Anderson and Johnson, 1970). In 1969, the Ebberts prospect was sampled by International Minerals and Chemicals (IMC) in the vicinity of the main shaft 

(Pilkington, 1970). IMC also excavated a dozer trench which crossed the Ebberts shear 

200 feet east of the Ebberts shaft.

Geologic description:

 This site consists of several claims containing gold-bearing quartz shear zones; these 

are the Pioneer, Willie, Iron Mask, War Eagle, Leroy and Black Warrior claims. Most 

production came from the Pioneer claim. 

 The Pioneer shaft and prospect pits exposed a shear zone of over 800 feet in strike 

length. By 1912, $22,000 worth of gold (1,064 ounces) of ore had been mined; the average width of the vein was 34 inches, and the average grade was 2.2 ounces of gold per 

ton. The highest value was obtained from a 22 ton shipment to the Chena mill which returned an average of $180 gold per ton (8.7 ounces of gold per ton) (Times Publishing 

Company, 1912). By 1916, two shafts had been sunk on the Pioneer claim on an 18-inchthick antimony-bearing shear zone oriented N 85 E, 80 N. (Mertie, 1918). Five hundred 

feet west of the antimony-bearing zone, three gold-bearing quartz stockwork shears were 

exposed. Two of these zones ranged from 12- to 14-inches-thick and were oriented N 35-

45 E, 60-80 NW. The third zone had an east-west strike and a dip of 45 S. These exposures averaged about $10 gold per ton or 0.5 ounces of gold per ton (Mertie, 1918). 

 The Willie claim contained a 4- to 5-foot-wide iron-oxide-stained quartz stockwork 

zone oriented N 50 E, 80 SE (Prindle, 1910). Free gold could be panned from its 1,000 

foot strike length. Shaft sinking in 1910 revealed a 10-inch-thick high grade portion of 

the shear zone.

 The Iron Mask claim contained an eight-foot-wide mineralized shear zone oriented eastwest and dipping 65 S. A 50-foot shaft had been sunk on this claim by late 1912 and the 

ore averaged $25 gold per ton or 1.2 ounces of gold per ton (Times Publishing Company, 

1912). A three-foot-wide, high grade zone was also exposed on the Iron Mask claim. 

This zone has a hanging wall consisting of a bleached white decomposed rock believed to 

be a fine-grained intrusive (Smith, 1913; B 525). The gold-bearing portion of the lode is 

in fault contact with the decomposed intrusive rock. On the Iron Mask claim, an 8-inchthick stibnite-bearing shear had been exposed which strikes N 80 W and dips 75 SW. 

Farther to the east but still on the Iron Mask claim, a 4-foot-thick shear zone carrying low 

grade gold and stibnite mineralization was exposed and traced into Fairbanks Creek. At 

the War Eagle claim, visible gold was found in two separate zones which average 1 to 2 

feet wide (Smith, 1913; B 525). In the Leroy claim, the high grade portion of the shear 

averaged 1 foot wide (Smith, 1913; B 525). The farthest east claim, the Black Warrior, 

contained test pits that exposed high grade gold-quartz shear zones which averaged 8 to 

10 inches wide. 

 The average fineness of the Pioneer group gold through 1912 was 814.5 (Smith, 1913; 

B 525).

Workings/exploration:

 Exploration began in 1904, and the Pioneer group of claims were eventually staked; 

these included the War Eagle, Leroy, Pioneer, Iron Mask and Black Warrior claims 

(Times Publishing Company, 1912). The adjacent Willie claim was staked in 1909. In 

the winter of 1910, shaft sinking was begun on the Willie claim. By 1912, the Pioneer 

shaft had been sunk to a depth of 120 feet and two other shafts sunk to depths of 49 and 

85 feet. Additional prospect pits have exposed the shear zone over 800 feet along strike. 

In early 1912, a 50-foot-shaft was sunk on the Iron Mask claim. By mid-1912, the western-most claim of the Pioneer group, the War Eagle claim, had been traced in several 8- 

to 10-foot deep pits (Smith, 1913; B 525). On the Leroy claim, two shafts were sunk on 

one of the leads that was exposed on the War Eagle claim. Development work on the 

Pioneer claim included about 200 feet of drifts to the east and west at the 110 foot level 

(Smith, 1913; B 525). Fifty feet of drift had been completed from the 75-foot level in the 

next shaft to the east and still further east, a 38-foot-deep shaft had been sunk. The farLG155

thest east claim of the Pioneer group, the Black Warrior claim, contained test pits 12- to 

15-feet deep every 50 feet over 400 to 500 feet along strike. By 1916, two shafts had 

been sunk on the Pioneer claim on an inch-thick antimony-bearing shear zone (Mertie, 

1918). 

 In 1951, dozer trenching at the Pioneer Group exposed the tops of the old drifts on the 

antimony shear zone (Saunders, 1960; ATDM MR 49-4, p.2). A shaft was sunk an additional 20 feet to determine if high grade stibnite mineralization was present (Saunders, 

1960; ATDM MR 49-4, p.2). In 1969, the Pioneer group of claims were examined by 

dozer trenching and rotary dirlling. Active exploration of the Pioneer mine area was conducted by Placid Oil in 1984 and 1985 when 2,154.7 feet of diamond core hole was 

drilled in 13 holes in the Pioneer and Pennsylvania mine site areas (Porterfield and Croff, 

1986). In 1988, BP Minerals conducted reverse circulation drilling in the Pioneer mine 

area (Freeman, 1992). 

Production notes:

 Production from the Pioneer mine through 1931 was estimated at $14,000 (677 ounces). 

This production was primarily derived from above the 50-foot level of the main shaft 

(Hill, 1933).

Additional comments:

 Angus McDougall conducted the first exploration in the vicinity of the Pioneer mine beginning in 1904 (Times Publishing Company, 1912). He and his partners Julius Hoffman, 

Mr. McGowan and Mr. Clark, eventually staked the Pioneer group which consisted of the 

War Eagle, Leroy, Pioneer, Iron Mask and Black Warrior claims (Times Publishing Company, 1912). The adjacent Willie claim was staked in 1909 by Lawrence J. McCarty. By 

1910 the Willie claim was owned by Frank Lawson and Lawrence McCarty and an unspecified amount of ore had been custom milled from the prospect (Brooks, 1910). In the 

winter of 1910, shaft sinking was begun on the Willie claim by Lawrence McCarty's sons, 

Lawrence Junior, age 9 and Willie, age 7. The two boys were assisted by their older sister 

who acted as surface superintendent (Times Publishing Company, 1912).

Geologic description:

 Free gold occurs associated with antimony oxides in white quartz in a shear zone that 

strikes N 76 W and dips 56 SW (Smith, 1913; B 525). The high grade portion of the shear 

zone averaged 12 to 15 inches thick. 

 In late 1911, an 8.5 ton sample of material from the claim averaged $100 gold per ton 

(4.8 ounces of gold per ton). A second lot of Pennsylvania mine ore was custom milled 

in early 1912 and averaged $52 gold per ton (2.5 ounces of gold per ton). By 1913, the 

Pennsylvania shaft was deepened to 146 feet and between 1922 and 1931; the west drift 

on the 50 foot level was extended to a length of 70 feet and stoped through to the surface. 

This work yielded approximately $10,000 worth of gold (484 ounces) (Hill, 1933). 

 The Pennsylvania mine was examined in 1942 as a possible source of antimony. A onehalf ton stockpile of oxidized stibnite near the shaft contained an average grade of 

57.01% antimony but the mine did not posses sufficient quantity of this material to warrant additional exploration or development (Killeen and Mertie, 1951).

Workings/exploration:

 By late 1912, the Pennsylvania shaft had been sunk to a depth of 140 feet. Drifting had 

proceeded 20 feet to the northwest and southeast on the 140 foot level. At the 50 foot 

level, drifts extended 50 feet northwest and 50 feet southeast with a raise connected to the 

surface on the southeast drift (Times Publishing Company, 1912). The ore was hoisted 

using a Little Giant steam hoist and was shipped to the company mill constructed on upper Fairbanks Creek by L.J. McCarty and Emil C. Fursteneau. This mill began operation 

on September 28, 1912 and consisted of a Little Giant #3 roll mill which fed minus 40 

mesh pulp over amalgamation plates (Times Publishing Company, 1912). The tailings 

were not impounded at this mill. The mill has a capacity of 8 to 20 tons of ore per day 

(Smith, 1913; B 525). The Pennsylvania shaft had been deepened to 146 feet by mid1913 (Chapin, 1914). At some point between 1922 and 1931, the western drift on the 50-

foot-level was extended to a length of 70 feet and stoped through to the surface. This 

work yielded approximately $10,000 worth of gold (484 ounces) (Hill, 1933). The shaft 

and workings were flooded in 1931. 

Production notes:

 In late 1911, an 8.5 ton sample of material from the claim averaged $100 per ton in gold 

(4.8 ounces of gold per ton). A second lot of Pennsylvania mine ore was custom milled 

in early 1912 and averaged $52 per ton (2.5 ounces of gold per ton). The mine was not in 

production in 1913. The mine was examined in 1922 by Stewart (1922) and Davis 

(1922) but was not in production at that time. At some point between 1922 and 1931, the 

western drift on the 50-foot level was extended to a length of 70 feet and stoped through 

to the surface. This work yielded approximately $10,000 worth of gold (484 ounces, Hill, 

1933).

Additional comments:

 The Pennsylvania claim was staked in October 1911 by Lawrence J. McCarty and soon 

became part of the McCarty group of claims which included the Pennsylvania, Willie, 

Dorothy, Marie, Kentucky and Freegold claims (Times Publishing Company, 1912).

Geologic description:

 In 1908, the Homestake Tunnel site, which is currently known as the Nordale adit, was 

staked (Times Publishing Company, 1912). Five gold-bearing, quartz-rich shear zones 

were located on the surface above the intended site of the Homestake adit (Smith, 1913; B 

525). Stibnite, pyrite and chalcopyrite were noted in a bulk sample. This material was 

extracted from a 3-inch-wide 'stringer' zone encountered in the adit approximately 315 

feet from the portal. The shear strikes east-west and dips 45 S (Brooks, 1914). Two drifts 

were driven along the 45 S, east-west trend of mineralization along this main stringer 

zone known as the Nordale shear (Times Publishing Company, 1912). 

 By mid-1913, the eastern drift on the Nordale shear was 300 feet long and two stopes 

had been mined out. The shear zone in the east drift is discontinuous along strike, and in 

both dip directions, although the mineralized shear zone appears to have the same orientation as barren portions of the shear zone. An 8-foot-deep winze on the east drift ore shoot 

indicated that the mineralization pinched out at depth and extended for a distance of 12 

feet along the dip slope. The ore shoot extends along the east drift floor for 160 feet from 

a point 90 feet east of the main adit. The eastern 50 feet of the east drift was barren. Approximately 135 feet east of the 315-foot station in the main adit, a 150-foot raise was 

driven on the Nordale shear which confirmed the presence of the shear zone to the surface. At a point 30 feet up-dip from the east drift, the raise intersected 10 dip-feet of mineralized shear zone which was stoped out over a 100-foot length. The upper ore shoot has 

LG157 
Alaska Resource Data File 

Page 349 

a horizontal pitch and is 3 to 12 inches thick and averages 9 inches thick (Brooks, 1914). 

The upper portion of the ore shoot is truncated by a horizontal fault of unknown displacement. Barren white quartz veins in the metamorphic country rock commonly increase in 

abundance near higher grade portions of the shear zone. At least two phases of mineralization are recognized in the east-drift stopes. Early quartz-rich lenses in the country rock 

are cut by later mineralized quartz veinlets in the shear zone. 

 At 600 feet from the Homestake adit portal, another shear zone trends N 60 W and dips 

45 S. The quartz-rich portions of the shear average 1 foot in width, but pinch and swell 

along strike. Mineralization consisted of poly-phase quartz containing free gold, stibnite, 

pyrite, chalcocite and copper carbonates. Total sulfide content is low. Bladed chalcocite 

associated with higher gold values is described by Brooks (1914) but probably is 

jamesonite or boulangerite (Freeman, 1992). 

 Development of the Nordale shear in the east drift of the Homestake adit in 1916 discovered another ore shoot in a raise approximately 100 feet up-dip from the east drift. 

The raise was driven approximately 235 feet east of the main Homestake adit (Brooks, 

1918; Stewart, 1922). The new ore shoot was similar in character to previously encountered shoots in the Homestake workings and strikes N 68 E and dips 40 SW. The horizontal fault which truncates the upper ore shoot in the adjacent raise was also encountered 

in the new raise where it had a strike of N 60 E with a dip of 30 NW. Gold mineralization was restricted to the quartz-rich portion of the shear zone and was associated with 

stibnite and minor pyrite and chalcocite. 

 Metallurgical work conducted on material from the Nordale shear zone revealed the 

presence of variable amounts of scheelite commonly associated with stibnite and high silver values (Hall, 1940). The high gold and silver content of the Nordale shear zone was 

investigated with a series of tests which indicated most of the gold was contained in 

quartz rather than sulfides, and sulfides were liberated at approximately 100 mesh. The 

highest gold and silver values were found in the -200 mesh size fraction. The silverbearing mineral is argentiferous tetrahedrite (Metz, 1987). 

 Plans to continue development and produce antimony from discrete stibnite pods in the 

mine were abandoned when assays indicated unacceptably high lead contents in the ore 

(Joesting, 1943). Analytical results from a dump sample of stibnite taken in 1942 returned a grade of 45.64% antimony (Killeen and Mertie, 1951). 

 A ten foot thick sequence of massive sulfide known as the Truck system was intersected 

in drilling beneath the Nordale adit. This mineralization was 10 feet thick and graded 

0.04 ounces of gold per ton, 12 ounces of silver per ton, 6.24% lead and 7.31% zinc 

(Porterfield and Croff, 1986). Mineralization was hosted by chloritic and manganiferous 

quartzite, graphitic schist and exhalite of the middle Cleary Sequence. 

 Samples from the Nordale adit dump contained highly anomalous gold, silver, arsenic 

and antimony hosted by chloritic and manganiferous quartzite, graphitic schist and exhalite of the middle Cleary Sequence (Fairbanks Exploration Inc., unpublished report, 

1986). Samples from the dump averaged 0.030 ounces of gold per ton and 0.25 ounces of 

silver per ton, with anomalous arsenic and antimony; visible galena, sphalerite and rare 

chalcopyrite are also present. 

 In early May, 1911, 1,300 tons of ore from the Homestake adit returned average grades 

of $470 per ton in gold (22.7 ounces of gold per ton). Smith (1913) reported that this 

bulk sample contained $308 per ton in free gold (14.9 ounces of gold per ton) with the reLG157

mainder of the values being in gold and high silver in concentrates not recoverable by 

amalgamation. Work at the Homestake adit continued in 1914, and 30 to 50 tons of ore 

were mined that contained approximately $100 of gold per ton (4.8 ounces of gold per 

ton) (Brooks, 1915; Stewart, 1915). Approximately 50 tons of ore was mined from the 

Homestake mine in 1915 and returned an average value of $100 per ton in gold (4.8 

ounces of gold per ton) (Smith, 1917; BMB 142). A total of 80 tons of ore of unknown 

grade was mined from the Homestake adit in 1916 (Mertie, 1918). 

 Gold production from the Homestake adit was estimated at $60,000 (about 2,900 

ounces) through 1931 (Hill, 1933). A total of 54 tons of ore from the Nordale shear were 

milled at the McCarty mill and returned an average grade of $52 of gold per ton (1.5 

ounces of gold per ton) (Reed, 1939).

Workings/exploration:

 In 1908, the Homestake tunnel, which currently is known as the Nordale adit, was 

staked (Times Publishing Company, 1912). Five, gold-bearing quartz-rich shear zones 

were located on the surface above the intended site of the Homestake adit (Smith, 1913; B 

525). Between October, 1908 and May 1911, the adit was driven approximately 315 feet. 

Work continued in the Homestake adit until November, 1912, when the adit was approximately 680 feet long. Work concentrated on the main stringer zone, now known as the 

Nordale shear, where two drifts were driven along the 45 degree south-dipping, east-west 

trend of mineralization. The western drift was 50 feet in length and the eastern drift had 

been driven 100 feet when mineralization was cut off by a fault (Times Publishing Company, 1912). By mid-1913, the eastern drift on the Nordale shear was 300 feet long and 

two stopes had been mined out. Approximately 135 feet east of the 315-foot station in 

the main adit, a 150-foot raise was driven on the Nordale shear which confirmed the presence of the shear zone to the surface. 

 By mid-1913, the Homestake adit had been extended to 750 feet in length and had intercepted three mineralized shear zones. In 1938, the Homestake adit was re-opened and 

200 feet of drift driven on the Nordale shear zone west of the main adit (Reed, 1939). A 

50-foot shaft was sunk on this shear and a 65-foot exploration adit driven on the nearby 

Wolf shear. By 1940, Hall (1940) reported the east drift of the Homestake adit to be 700 

LG157

Page 351 

feet long with little or no cross-faults along this length. Development efforts at the 

Homestake adit were terminated by War Production Board Limitation Order L208 in 

1942. 

 In 1982, Placid Oil Company (POC) began rehabilitation of the Homestake adit, now 

known as the Nordale adit (Porterfield and Croff, 1986). Efforts in 1982 consisted of rehabilitation of 950 feet of old adit and completion of 1,561 feet of new adit and drift. Of 

this total, 600 feet of drift was driven west of the main adit to access the Christina shear 

zone and 250 feet of cross-cut was driven to access the shear zone along strike. In 1983, 

POC drove an additional 163 feet of drift east of the main adit and 103 feet of new drift 

west of the main adit. POC also completed 700 feet of underground diamond drilling in 

7, BQ (1.433 inch) wireline holes (Porterfield and Croff, 1986). Placid Oil did not conduct any work on the Nordale shear zone and the east and west drifts remained caved. 

 In the spring of 1986, the portal of the Nordale adit caved and the adit has remained inaccessible since that time. The prospect was examined in 1986 by Fairbanks Exploration 

Inc. and grab samples were collected from a small portion of the Nordale adit dump. 

Production notes:

 In early May, 1911, 1,300 tons of ore from the Homestake adit returned average grades 

of $470 per ton in gold (22.7 ounces of gold per ton). Smith (1913, B 525) reported that 

this bulk sample contained $308 per ton in free gold (14.9 ounces of gold per ton) with 

the remainder of the values being in gold and high silver in concentrates not recoverable 

by amalgamation. Work at the Homestake adit continued in 1914, and 30 to 50 tons of ore 

were produced that contained approximately $100 per ton in gold (4.8 ounces of gold per 

ton) (Brooks, 1915; Stewart, 1915). Approximately 50 tons of ore was mined from the 

Homestake mine in 1915 and returned an average value of $100 per ton in gold (4.8 

ounces of gold per ton) (Smith, 1917; BMB 142). A total of 80 tons of ore of unknown 

grade was mined from the Homestake adit in 1916 (Mertie, 1918). 

 Gold production from the Homestake adit was estimated at $60,000 (2,900 ounces) 

through 1931 (Hill, 1933). A total of 54 tons of ore from the Nordale shear were milled 

at the McCarty mill and returned an average grade of $52 per ton (1.5 ounces of gold per 

ton) (Reed, 1939).

Geologic description:

 Gold is found in quartz-rich shear zones. Mining initially began on a 3- to 5-foot wide 

shear zone trending N 25 E, 25 NW (Smith, 1913; B 525). Samples collected from the 

Rexall mine in 1910 averaged 6 ounces of gold per ton. By 1911, an adit had been driven 

127 feet and 50 feet of drift had been driven on a quartz-rich shear zone that varied from 

8 to 32 inches wide (Brooks, 1912). A richer ore shoot was intersected about 140 feet 

from the portal of the Rexall adit. This zone contained a 1- to 8-inch-wide quartz-rich 

shear that trends east-west and dips 60 N. The smaller shear is offset a few feet by the 

larger shear (Smith, 1913; B 525). 

 By November, 1912, a total of 340 feet of drift had been driven on the smaller shear and 

two winzes and five production stopes were ready for mining. The smaller shear zone 

was intersected in the main Rexall adit approximately 140 feet below the surface. Several 

custom lots of Rexall ore were milled in Fairbanks during 1912. A 25 ton lot from the 

small shear averaged $112 per ton in free gold (5.4 ounces of gold per ton); a 10 ton lot 

from the small shear averaged $166 of gold per ton in free gold (8.0 ounces of gold per 

ton) and a 3 ton lot from the large shear averaged $37 of gold per ton, or 1.8 ounces of 

gold per ton (Smith, 1913; B 525).

Workings/exploration:

 The Rexall mine was discovered by J.L. Solomon in March, 1910, and shortly afterwards, he staked four claims on the property (Times Publishing Company, 1912). Mining 

was started on a 3- to 5-foot-wide shear zone oriented N 25 E, 25 NW (Smith, 1913; B 

525). By the end of 1911, an adit had been driven 127 feet, and 50 feet of drift cut on a 

quartz-rich shear zone that varied from 8 to 32 inches wide (Brooks, 1912). By mid1912, a richer ore shoot was intersected about 140 feet from the portal of the Rexall adit. 

Work on the larger, northeast-trending shear was abandoned and a winze was sunk to the 

water table on the smaller, east-west trending shear. A total of 340 feet of drift had been 

driven on the smaller shear; two winzes and five production stopes were ready for mining 

by November, 1912. The smaller shear zone was intersected in the main Rexall adit approximately 140 feet below the surface. 

 In the fall of 1912, a two-stamp Joshua Hendy mill was erected on the Rexall claim and 

began milling ore in November, 1912. By this time the Rexall adit was 485 feet long and 

six stopes were ready for mining (Times Publishing Company, 1912). 

Production notes:

 Over the winter of 1911-1912, approximately 25-tons of ore were custom milled; they 

averaged $120 per ton or about 5.8 ounces per ton gold (Times Publishing Company, 

1912). Several custom lots of Rexall mine ore were milled in Fairbanks during 1912. A 

25 ton lot from the small shear averaged $112 per ton in free gold (5.4 ounces per ton 

gold), a 10 ton lot from the small shear averaged $166 per ton in free gold (8.0 ounces per 

ton gold) and a 3 ton lot from the large shear averaged $37 per ton in free gold, or about 

1.8 ounces of gold per ton (Smith, 1913; B 525). In the fall of 1912, a two-stamp Joshua 

Hendy mill was erected on the Rexall claim and began milling ore on November 28, 

1912. By this time the Rexall adit was 485 feet long and six stopes were ready for production (Times Publishing Company, 1912). No references to the Rexall mine are available for the period 1913 through 1921. By 1922, Davis (1922) and Stewart (1922) reported that the Rexall mill had been sold to the owners of the David mine and moved to 

Skoogy Gulch.

Geologic description:

 In 1996, Freegold Recovery Inc. outlined a +5,000 foot long multi-element soil anomaly 

on the Goose Creek prospect (Freeman and others, 1998). The core of the grid, covering 

an area approximately 2,000 feet by 1,000 feet, averaged over 100 ppb gold, three times 

the mean gold value over the project area. This anomaly trends N 80 W and was extended to a length of +10,000 feet in 1997. The anomaly is located in lower plate rocks of 

the Fairbanks Schist and appears to have secondary anomalies associated with district 

scale northeast trending structures similar to those on the Cleary Hill (ARDF no. LG119), 

Dolphin (ARDF no. LG112) and Wolf Creek (ARDF no. LG138) prospects. Initial drilling in late 1997 consisted of 5,038 feet of reverse circulation drilling in 11 holes. Preliminary assay results from one hole returned intercepts averaging up to 0.118 ounces of 

gold per ton over 160 feet in highly sericitized chlorite schist cut by 10-20% white quartz 

veins. Anomalous gold is associated with anomalous As, Sb, Pb, Ag, and Zn. Pyrite is 

relatively abundant in the sericitic alteration envelope but does not appear to be correlative with gold values. 

 In 1998, 10 reverse circulation holes totaling 5,017 feet were drilled in the Goose Creek 

prospect to determine the extent and geometry of the higher grade intercepts encountered 

in the 1997 drill program. Results indicate that mineralization is controlled by an 85 degree south dipping structure. The gold-bearing alteration envelope around this structure is 

restricted in size indicating limited potential for bulk tonnage mineralization in this area.

Geologic description:

 Prior to 1969, the divide between Too Much Gold Creek, Fairbanks Creek and Wolf 

Creeks was host to several producing mines and numerous prospects. The target of all of 

these mines and prospects was high grade gold mineralization associated with large northwest and northeast trending shear zones. Low grade mineralization was known to be present on these properties within and along the margins of higher grade portions of the shear 

zones. However, these lower grade zones could not be profitably worked using the existing technology (W. McCarty, oral commun., 1988). In 1969, International Minerals and 

Chemicals (IMC) conducted an exploration program designed to address the possibility of 

surface mining the lower grade material in this area. This work had been prompted by the 

findings presented in Forbes and others (1968) and Pilkington and others (1969) which 

indicated significant low grade gold and silver mineralization around higher grade quartzrich portions of the shear zones. IMC conducted trenching and rotary drilling targeted at 

low grade gold-silver mineralization in surface mineable zones adjacent to previously 

mined high grade shear zones. These activities resulted in discovery of the Circle Trail 

prospect. 

 IMC's exploration efforts on the Circle Trail prospect consisted of geological mapping, 

grid rock and soil sampling, and excavation of 4 dozer trenches totalling 1874 feet 

(Pilkington, 1970). In order to test the down-dip extent of mineralization picked up in 

trenches, IMC conducted rotary drilling using a 5-inch-diameter conventional rotary drilling rig (Pilkington, 1970). A total of 12 vertical holes totalling 2,250 feet was drilled on 

LG162

Page 363 

the Circle Trail prospect in 1969. Based on this drilling and trenching IMC calculated reserves of 1,050,000 tons with 0.050 ounces of gold per ton and 2.09 ounces of silver per 

ton (Pilkington, 1970). 

 In 1988, BP Minerals conducted additional drilling as operator of a joint venture with 

Fairbanks Exploration Inc. This program was designed to test for the suspected northwest 

trending shear zones previously mapped in the area. BP Minerals constructed 2,100 feet 

of new access road and drilled 2,362 feet of reverse circulation drilling in five holes 

(Klessig, 1988). Based on the work conducted by IMC and BP Minerals, Fairbanks Exploration Inc. estimated indicated reserves for the Circle Trail zone of 449,808 tons grading 0.070 ounces of gold per ton equivalent to a depth of 50 feet (P. Metz, written commun., 1988). No additional work has been conducted on the project since 1988. 

 The following is a summary of some of the characteristics of the Circle Trail prospect 

(Freeman, 1991). Mineralization is hosted by both northeast-trending gold-silversulfosalt-bearing, D2 shear zones and later northwest-trending gold-silver-arsenicbearing, D3 shear zones. These shears are hosted by flat-lying felsic metavolcanics and 

metaquartzites of the middle to upper Cleary sequence. Rocks encountered in trenching 

and drilling include chloritic quartzite, chlorite schist, quartzite and quartz-chlorite-biotite 

schist. Sulfide minerals have been oxidized to depths that vary from 80 to 340 feet below 

surface. 

 Below the oxide zone, arsenopyrite, pyrite, boulangerite and jamesonite have been identified. Gold and silver values are not always elevated where iron, arsenic or lead sulfides 

occur, but sulfides containing these metals usually are present where gold and silver values are anomalous. Drilling intercepted five separate shear zones over a strike length of 

1,500 feet and a combined width (perpendicular to strike) of 1,000 feet. The Circle Trail 

prospect extends along strike for 10,000 feet, is 1,800 feet wide and has been tested over 

a vertical distance of 700 feet in drilling, trenching and mining. Mineralization remains 

open in all directions.

that dips 60 S. Some quartz stringers that were said to carry gold were intercepted by the 

tunnel, but they were too small to be mined. A shaft was sunk just above the north end of 

the tunnel and uncovered a narrow lode of crushed and recemented quartz. Stibnite was 

observed in irregular patches and was reported to be fairly common throughout the 

quartz; it showed the usual oxidation to secondary antimony oxides. The prospect did not 

produce prior to 1912 and contained only low gold values of unspecified grade (Smith, 

1913; B 525). 

 The prospect was examined as a possible antimony producer in 1916 but contained insufficient grade to warrant additional exploration or development (Brooks, 1916; B 649).

through which the adit cuts dips 10 to 15 N. In 1922, the adit was 1,000 feet in length (N 

30 E trend), contained cross-cuts at the 700-, 800- and 1,000-foot stations, and connected 

the Mizpah and Ohio mine workings to the Gilmore mill (Davis, 1922). At the 700-foot 

station, a thin stringer was followed in a 50-foot long drift to the northwest. At the 800-

foot station, the northwest drift is 100 feet long and the southeast drift is 75 feet long. At 

the 1,000-foot station, the southeast drift runs 150 feet to the upper shaft on the Ohio

had an upper shaft 45-feet deep and a lower shaft 60-feet deep. The upper shaft is driven 

on a northeast striking shear. The lower or southern shaft is driven on two northwesttrending, steeply south-dipping shear zones with vertical slickensides that indicate southside-down motion (Brooks, 1913, p. 148). 

 In 1916, several shafts were accessible on the Ohio prospect and were examined by 

Mertie (1918). A 25-foot-deep shaft on the prospect exposed two coalescing quartz-rich 

zones that strike N 70 W and dip 45 SW. This ore was considered to be of commercial 

grade, i.e., approximately 1 ounce of gold per ton. A 57-foot-deep shaft exposed an 8-

inch-wide shear zone that assayed $4 to $5 per ton in gold (0.19 to 0.24 ounces of gold 

per ton). This shear strikes east-west and dips 45 N. A 70-foot-deep shaft had 70 feet of 

drift at the bottom of the shaft. A gold-bearing, quartz-rich shear zone in this drift averages 4 to 6 inches thick, strikes east-west, and dips 45 SW. This material also was considered to be of commercial grade and carried accessory pyrite and stibnite. Up slope 

from the 70-foot-deep shaft is a 30-foot-deep shaft driven on a base-metal-rich shear zone 

containing arsenopyrite, pyrite and quartz. This rock reportedly has high silver values and

contained what was thought to be native silver (bismuth?) similar to that identified at the 

adjacent Mizpah mine (Mertie, 1918). Ore grades in 1912 were estimated at $50 per ton 

in gold (2.4 ounces of gold per ton) with minor silver (Smith, 1913; B 525).

 In 1912, the Ohio claim had a 50-foot-shaft which exposed a high grade stringer that 

varied from 6 to 20 inches wide (Times Publishing Company, 1912). The Mayflower 

claim had an upper shaft 45 feet deep and a lower shaft 60 feet deep. By 1914 the Ohio 

shaft was 80 feet deep. 

 A five-stamp mill (see Gilmore prospect) was erected southeast of the Ohio mine in 

1915 and operated from September 1 through the end of the year on ore from the Ohio 

mine and other producers in the area (Brooks, 1915; Smith, 1917; BMB 142). An adit 

was collared in 1915 which was planned to extend 800 feet at N 30 W to intersect the 

Ohio shear zone below the surface weathering zone which had hampered mining on the 

prospect. By August, 1916, this adit was 240 feet long (Mertie, 1918). In 1916, several 

shafts were accessible on the Ohio prospect and were examined by Mertie (1918). The 

Ohio prospect was inactive and the workings obstructed with ice when the prospect was 

examined in 1931 (Hill, 1933). 

Production notes:

 The Ohio mine operated in 1914 but production figures are not available (Eakin, 1915). 

By 1916, the Gilmore mill had treated approximately 350 tons of ore from the Ohio mine 

(Mertie, 1918).

Geologic description:

 This prospect contains a silver and gold-bearing carbonate-rich shear zone. The country 

rock is schist that strikes east-west and dips to the south at a shallow angle parallel to the 

schist (Brooks, 1913, p. 146). 

 Prior to 1912, a 26-foot-deep shaft was sunk on the prospect and exposed the silver- and 

gold-bearing, carbonate-rich shear zone. In the summer of 1912, a 4- to 18-inch-wide 

cross-shear had been discovered on the prospect. A high grade sample from this crossshear averaged over 820 ounces of gold per ton (Times Publishing Company, 1912). A 

15-foot-deep test pit on this cross-shear exposed an east-west striking, steeply dipping 

quartz-bearing shear zone that varied from 3 inches to 2 feet wide (Smith, 1913, B 525; 

Brooks, 1913). The shear zone material was heavily stained by iron-oxides (Brooks, 

1913, p. 146). Later phase, crystalline quartz vugs also contained iron-oxides after sulfides (Brooks, 1913, p. 146). By 1913, the shear zone had been traced for approximately 

1,500 feet along strike and 1.5 tons of material had been stockpiled for later shipment to a 

nearby custom mill (Brooks, 1913, p. 146). Hill (1933) reported that exposures on the 

Plumbum prospect indicated the shear zone strikes N 70 W and dips 70 S. The prospect 

had not been worked for some time prior to 1931.

Geologic description:

 By 1912, an 18-foot-deep pit had been excavated and exposed a highly brecciated 

quartz-rich, shear zone cemented by pyrite, galena and stibnite (Smith, 1913; B 525). 

This brecciation post-dates an auriferous quartz stockwork zone from which a small 

amount of material had been sacked for shipment to a nearby custom mill. Several white 

porphyritic granite dikes up to 70 feet wide were exposed in the immediate vicinity of this 

exposure. These dikes are roughly parallel to the gold-quartz shear zone which strikes N 

70-80 W and dips vertically. This granite was not thought to be highly mineralized however, no analytical data are available (Smith, 1913; B 525). In late 1915, about 30 tons of 

ore from the prospect was custom milled and some development work was carried out 

(Stewart, 1915; Smith, 1917, BMB 142). The workings on the Whitehorse prospect were 

caved by 1931 and the site was still inactive in 1942 (Hill, 1933; Killeen and Mertie, 

1951). 

 In 1969, International Minerals and Chemicals Company conducted soil sampling at the 

site and excavated a 700 foot dozer trench across the Whitehorse shear zone to follow-up 

soil geochemical anomalies (Pilkington, 1970). This trench was oriented north-south and 

the shear zones exposed in the trench coincided with soil geochemistry. Sporadic gold 

was encountered in this trench; one, five-foot sample contained 1.2 ppm gold (0.035 

ounces of gold per ton). The host for this mineralization is unknown.

 The Governor prospect was originally staked by Aaron and Matt Cook as the Governor 

and Mayor claims on August 15, 1910 (Times Publishing Company, 1912). Three and 

one-half tons of ore from the Governor mine were custom milled in December 1910 and 

averaged $73 gold per ton (3.5 ounces of gold per ton) (Times Publishing Company, 

1912). By 1911, a 30-foot-deep shaft had been sunk on a one-foot-wide shear zone 

(Brooks, 1912). By 1912, the shaft had been deepened to 70 feet and 40 feet of drift had 

been driven from the bottom of the shaft (Times Publishing Company, 1912). The workings were driven on a vertically-dipping, N 80 W striking, shear zone which varied from 8 

to 30 inches wide (Smith, 1913; B 525; Times Publishing Company, 1912). Some of the 

ore was derived from a fine grained granitic rock which carried $10 to $15 gold per ton 

(0.48 to 0.72 ounces of gold per ton). This rock contains iron stained vugs where sulfide 

minerals have been oxidized. The granitic rock is highly sheared and slickensided. In 

1912, the possible extension of the Governor shear was being prospected approximately 

900 feet east of the Governor shaft (Smith, 1913; B 525). 

 In 1969, International Minerals and Chemicals Company conducted soil sampling and 

excavated an 805 foot trench across the Governor shear zone to follow-up soil geochemical anomalies (Pilkington, 1970). This trench was oriented north-south and although 

shear zones exposed in the trench coincided with soil geochemistry anomalies, no signifiLG172

Geologic description:

 Smith (1913, B 525) reported a shear zone with quartz-rich intervals from 6 inches to 2 

feet wide, although mineralization in the surrounding wall rocks made an ore zone up to 6 

feet wide. The hanging wall of the shear is highly faulted and slickensided with postmineral motion visible. The foot wall contains mixed wall rock and quartz and the contact is not faulted above the 80-foot station in the shaft. Below the 80-foot station both 

the hanging wall and foot wall appear to be fault contacts (Smith, 1913; B 525). 

 By 1912, the shear zone hosting the gold was traced for over 1,700 feet along its eastwest strike and the high grade portion of the shear was 8 to 18 inches wide and dipped 65 

N (Times Publishing Company, 1912). In the fall of 1911, a one ton sample of ore from 

this zone was custom milled and averaged $60 per ton in gold (2.9 ounces of gold per 

ton). An additional 1.5 tons of material was custom milled in 1911 and 4 tons of material 

were custom milled in the spring of 1912 (Smith, 1913; B 525). The grade of these two 

lots is unknown. 

 By 1922, the Hi Yu shear zone (ARDF no. LG182) had been traced to the northwest 

and identified as the same shear zone as the Nars Anderson (Davis, 1922).

Workings/exploration:

 The Nars claim was staked on September 14, 1911 by Otto Nars (Times Publishing 

Company, 1912). By October, 1912, a shaft had been sunk to depth of 105 feet with 

working drifts on the 60- and 100-foot levels. On the 60-foot level drifts extended 50 feet 

to the west and 25 feet to the east. At the 100-foot level, a drift extended 10 feet on each 

side of the shaft. Bad air in the shaft curtailed operations in 1912 until artificial ventilation could be provided. At that time about 2.5 tons of material was sacked and stockpiled 

at the mine site awaiting custom milling. A small boiler and steam hoist had been erected 

over the shaft and work continued through the winter of 1912. In 1915, the workings on 

the prospect consisted of a 100-foot adit and a 100-foot deep shaft with working levels at 

60 and 100 feet (Brooks, 1916; B 642). By 1922, the drifts on the 60-foot level were 50 

and 60 feet long (Davis, 1922). Production to 1922 was estimated at 200 tons of ore and 

subsequent mining of the Nars Anderson prospect was expected to be conducted through 

the upper adit at the Hi Yu mine. 

 In 1985, Placid Oil Company drilled two diamond drill holes on the Nars Anderson 

prospect. Placid Oil Company records refer to this prospect as the Dorando prospect and 

mistakenly refer to the Rob Roy prospect as the Nars Anderson prospect. Holes 1DD-85 

and 2DD-85 were drilled to the south at inclinations of 70 and 85 degrees to a total depth 

of 179 and 185 feet, respectively (Porterfield and Croff, 1986). No significant mineralization was encountered and no additional work has been conducted on this prospect. 

Production notes:

 Production to 1922 was estimated at 200 tons of ore; subsequent mining of the Nars 

Anderson prospect was expected to be conducted through the upper adit at the Hi Yu 

mine (Davis, 1922).

Geologic description:

 This prospect was discovered in the early 1980's when Placid Oil Company conducted 

soil sampling over the Wolf Creek and Too Much Gold Creek basins (Porterfield and 

Croff, 1986). This work outlined extensive gold and arsenic soil anomalies extending 

over 10,000 feet on a west-northwesterly trend from the southwest side of lower Too 

Much Gold Creek to near the junction of Goose Creek and Wolf Creek. The soil samples 

defined two parallel gold-arsenic soil anomaly zones in the Too Much Gold Creek basin 

with values ranging from 400 to over 1,000 ppm arsenic and 1 to over 3 ppm gold. 

 In 1985, Placid Oil drilled three diamond drill holes in the Wolf Creek basin in an attempt to determine the source for the gold-arsenic soil anomaly in this area. These holes 

intersected the lower exhalitive unit of the Cleary sequence which contained disseminated sulfides and stibnite but no significant gold mineralization (Porterfield and Croff, 

1986). Placid Oil also drilled two diamond drill holes on the gold-arsenic soil anomaly in 

the Too Much Gold Creek basin. These two holes failed to intersect significant mineralization. Placid Oil Company conducted no further work on the prospect. 

 A total of eight trenches covering 3,942 feet were excavated, following up on the soil 

anomalies (Klessig, 1988). Following the return of trench analyses, a total of 2,476 feet 

of reverse circulation drilling was completed in 8 holes. Trenching and drilling were concentrated on the smaller, southwestern, linear gold-arsenic soil anomaly. Significant mineralization was encountered in trenching and drilling. Based on these results, inferred reserves for the Too Much Gold zone are 1,613,885 tons that contain 0.065 ounces of gold 

LG178

per ton to a depth of 50 feet (P. Metz, written commun., 1988). 

 Freeman (1992) summarized the following important characteristics of the Too Much 

Gold prospect. Mineralization is hosted by highly oxidized metarhyolite tuff, iron-oxide 

stained chloritic schist, and quartzite. Except for sporadic silver-sulfosalts, sulfide minerals are rare in the Too Much Gold prospect trenches due to intense supergene and possible 

hypogene oxidation. Small amounts of oxidized argentiferous tetrahedrite and 

jamesonite-boulangerite are present where elevated silver grades occur. Oxidation of pyrite, arsenopyrite and lead-silver-antimony sulfosalt minerals results in intense red hematite, limonite, kermesite, apple-green scorodite, and white to pale-yellow stibiconitecervantite. Gold mineralization is accompanied by an average of less than 10% white to 

clear quartz veinlets. Anomalous gold commonly is associated with elevated silver, arsenic, antimony, lead and zinc. The trenching indicated that a poorly defined shear zone 

hosts significant gold and silver mineralization; it trends approximately N 80 W through 

the prospect from Too Much Gold Creek to the ridgeline between Goose Creek and Too 

Much Gold Creek.

Geologic description:

 By 1911, several prospect pits were reported along a 7-foot-wide mineralized zone containing $10 to $20 gold per ton (0.5 to 0.9 ounces of gold per ton) and $15 to $30 silver 

per ton (30 to 60 ounces of silver per ton, Brooks, 1911). A second shear contained 

chiefly galena with about $5 gold per ton (0.25 ounces of gold per ton). An unspecified 

amount of ore from the Excelsior prospect was custom milled in Fairbanks by 1911; however, production figures are not available. 

 By 1912, a southern adit 70 feet long and a northern adit 60 feet long had been driven. 

Both adits are located on the right-limit wall of Too Much Gold Creek. The shear averages 12 feet wide in the adits, and trends east-west with a steep south dip (Times Publishing Company, 1912; Smith, 1913; B 525). The ore in the adit contained 22 ounces of silver per ton. In the 70 foot adit, a drift had been turned off to the south on a crosscutting 

shear zone. The country rock in both adits consists of hard quartzite with lesser black carbonaceous schist (Smith, 1913; B 525). High silver grades in the northern adit are in carbonaceous schist that contains minor galena, arsenopyrite and stibnite. Above the Excelsior adits, exposures of fine grained quartz porphyry granite appear to be related to the 

mineralization in the Excelsior adits. This rock contains small cavities surrounded by limonite after sulfides. Although iron staining is pervasive in this rock, no metallic minerals were noted (Smith, 1913; B 525). 

 The Excelsior prospect was examined in 1916 to determine if commercial quantities of 

LG179

antimony existed; however, insufficient quantities were found to warrant exploration and 

development (Brooks, 1916; B 649). The Excelsior prospect was again examined in 1942 

to determine if commercial quantities of antimony existed, however insufficient quantities 

were found to warrant exploration and development (Killeen and Mertie, 1951).

Geologic description:

 The Mizpah shear zone in the main shaft trends east-west and dips 75 S (Smith, 1913; B 

525). The shaft exposed a high-grade, quartz-rich shoot which averages 2 feet in width. 

The Mizpah shear was traced to the northwest where the Black Joe claim was staked and 

a 12 foot prospect pit showed that the high grade portion of the shear was 2.5 feet thick 

(Times Publishing Company, 1912). The Mizpah shear contains gold and minor sulfides 

in a highly sheared quartz stockwork zone on the 80-foot level; strike-slip motion was 

noted. The gold-bearing quartz-rich zones mined to 1918 varied from 3 inches to 3 feet 

in width and averaged 1 foot wide. The gold-bearing shoots clearly cross-cut earlier, barren bull-quartz bodies (Mertie, 1918). 

 Antimony-gold-lead-silver ore in an earthy manganese wad was encountered at the 60 

foot station of the east drift on the 80-foot level (Mertie, 1918). Stibnite was encountered 

at the 80-foot station on the west drift of the 80-foot level. Stibnite in the Mizpah mine 

contained extremely high gold values up to $2,000 per ton (96.7 ounces of gold per ton). 

The average grade of ore mined through 1916 was $30 to $40 per ton in gold (1.4 to 1.9 

ounces of gold per ton). 

 In addition to gold, antimony, lead and silver, tungsten in the form of scheelite was 

identified on the Mizpah and Black Joe claims (Capps, 1924). Quartzite comprises the 

country rock in the Black Joe shaft; it strikes N 20 W and dips 18 SW. The shear zone 

being mined ranged in dip from 45 to 85 S. Gold values were higher and tungsten values 

LG180 
Alaska Resource Data File 

Page 403 

lower on the 60-foot level, while gold values are lower and tungsten values higher between the 60- and 80-foot levels (Mertie, 1918, p. 421). 

 By 1922, the Mizpah shaft was 220 feet deep (Davis, 1922; Stewart, 1922). Working 

drifts had been opened on the 80, 160 and 220 levels. Working drifts on the 80 foot level 

extended for 100 feet to the east and west from the shaft. Working drifts on the 160- and 

220-foot levels extended for 100 feet to the east and 175 feet to the west from the shaft. 

The east drift on the 200-foot level was connected to the Gilmore adit via a 350-foot drift 

driven from the 1,000-foot station of the Gilmore adit. Davis (1922) also reported a second shaft had been sunk on a parallel shear zone 150 feet from the Mizpah shear. This 

shear contains 20% stibnite with minor gold and was being explored from a 120-foot deep 

shaft. Production through 1922 was estimated at 1,500 tons grading $25 per ton (1.2 

ounces of gold per ton) (Davis, 1922). 

 Hill (1933), sampled fractured schist, with little or no quartz, at the face of the western 

drift; it contained $2.30 per ton in gold (0.11 ounces of gold per ton) over a width of 16 

inches. 

 The Mizpah mine was examined as a possible antimony and/or tungsten producer in 

1942 however, the mine was not found to contain either element in amounts which justified exploration or development (Killeen and Mertie, 1951; Byers, 1957). In late 1991, 

Dave Ebberhardt conducted limited dozer trenching on the Mizpah shear zone and exposed black-brown manganese wad on the main shear zone (R. Vetter, oral commun., 

1991). The Black Joe claim remained inactive.

 By late 1912, the Mizpah shaft had been sunk to a depth 120 feet with 50 feet of drifts 

on the 80- and 100-foot levels. The prospect remained idle until late in 1914 when development work was renewed (Eakin, 1915). By 1915, the mine was in production and was 

treating its ore at the nearby Heilig mill on Fairbanks Creek. A new headframe and steam 

hoist were installed to facilitate additional development (Stewart, 1915; Brooks, 1916, B 

642; Smith, 1917, BMB 142). Mertie (1918) reported a shaft driven to a depth of 90 feet 

on the Black Joe claim and development drifts on the 60- and 80-foot levels. 

 The Mizpah shaft had been extended to 160 feet deep in 1917 and the western drift on 

the 80-foot level had been stoped to the surface over a distance of 170 feet (Chapin, 

LG180 
Alaska Resource Data File 

Page 404 

1919). The mine was equipped with a Huntington mill situated on Fairbanks Creek below the mine. The Gilmore adit, collared at the Mizpah mill site, was 800 feet long in 

1917 and nearing intersection with the Mizpah mine workings (see Gilmore prospect). 

By 1918, the Mizpah mine shaft was 200 feet deep and production was continuing 

(Martin, 1920). By 1922, the Mizpah prospect was owned by Charles Thompson and associates and the shaft was 220 feet deep (Davis, 1922; Stewart, 1922). Working drifts 

had been opened on the 80-, 160- and 220-foot levels. Working drifts on the 80-foot level 

extended for 100 feet to the east and west from the shaft. Working drifts on the 160- and 

220-foot levels extended for 100 feet to the east and 175 feet to the west from the shaft. 

The east drift on the 200-foot level was connected to the Gilmore adit via a 350 foot drift 

driven from the 1,000-foot station of the Gilmore adit. Davis (1922) also reported a second shaft had been sunk on a parallel shear zone 150 feet from the Mizpah shear. 

 In 1923, the only activity recorded at the Mizpah mine involved timber repair in the Gilmore adit (Stewart, 1923). When visited in 1931, Hill (1933) reported the shaft caved at 

the 130-foot level. The drift on the 80-foot level was open for 120 feet to the face, but the 

east drift on the 80-foot level was caved 50 feet from the shaft. 

 In late 1991, Dave Ebberhardt conducted limited dozer trenching on the Mizpah shear 

zone. 

Production notes:

 In late 1911 six tons of high grade ore from the main shaft had an average grade of $100 

per ton in gold (4.8 ounces of gold per ton). A three-ton lot of ore from the Mizpah shear 

was milled in 1912 and returned average values of $92 per ton in gold or 4.4 ounces of 

gold per ton (Smith, 1913; B 525). Development work continued on the Mizpah prospect 

in 1913 but no production was recorded (Chapin, 1914). The prospect remained idle until 

late in 1914 when development work was renewed (Eakin, 1915). By 1915, the mine was 

in production and was treating its ore at the nearby Heilig mill on Fairbanks Creek. In 

1916, the Mizpah mine was in production for several months and produced 200 tons of 

ore (Mertie, 1918). Production through 1922 was estimated at 1,500 tons grading $25 in 

gold per ton (1.2 ounces of gold per ton) (Davis, 1922).

 The Mizpah claim was staked by August Hess on October 8, 1910 (Times Publishing 

Company, 1912). By 1912, additional partners in the claim included R.J. Geis and Charles L. Thompson.

Geologic description:

 Gold is found in three or four nearly parallel veins of quartz enclosing masses of schist 

(Chapin, 1914, p. 329). Limonitic material taken from the dump is said to occur in veinlike bodies parallel to the quartz vein; it contains small amounts of both gold and silver 

(Chapin, 1914, p. 329). Narrow reticulating veinlets of stibnite occur in both quartz and 

schist, and yellow-green stains of antimony-oxide is abundant (Chapin, 1914, p. 329). 

The high grade portion of the shear zone was 2-feet-wide (Times Publishing Company, 

1912, p. 22). The shear zone strikes N 80 W and dips 60 S. in quartz-mica schist 

(Chapin, 1914, p. 329). 

 The prospect was examined in 1942 as a possible source of antimony but did not exhibit 

sufficient antimony mineralization to warrant further exploration or development (Killeen 

and Mertie, 1951).

Geologic description:

 The Hi-Yu mine was one of the major producers in the Fairbanks district prior to 

WWII. This mine consists of many quartz veins, some along faults and most offset by 

faults, containing free gold and sulfides including stibnite, argentiferous galena, arsenopyrite, pyrite, and sphalerite (Cobb, 1976; OFR 76-633). 

 Before 1913, the Hi-Yu shear was traced over 900 strike feet over a vertical range of 

625 feet before an adit was collared on the right limit of Moose Creek (Prindle, 1913; 

Smith, 1913; B 525). By 1913, the Main adit was 450 feet long. A second adit known as 

the Lower adit, was collared in 1913. The northwest-trending, south-dipping shear zones 

containd several ore shoots over the 3,000 foot strike length outlined on the surface 

(Chapman, 1914). A twenty-three-ton lot of ore from the first 150 feet of the Main adit 

yielded 6.29 ounces of gold per ton. This gold had a fineness of 850 to 857 and contained 

13 to 14% silver (Chapman, 1914). By 1916, the Lower adit had been abandoned and a 

new adit, the Hi-Yu adit wa collared on the Hi-Yu claim approximately 500 feet above 

the level of Moose Creek (Stewart, 1922). A the 350 foot station of the Hi-Yu adit, the 

lode bifurcated. The northern branch, striking N 75 W and dipping steeply south, was 

traced for an additional 125 feet underground and could be followed on the surface for 

over 2,000 feet from the portal of the Upper adit (Mertie, 1918). By 1920, the Hi-Yu adit 

had been driven 1,300 feet. The average recovered grade of the ore in 1922 was $25 to 

LG182 
Alaska Resource Data File 

Page 409 

$30 gold per ton (1.21 to 1.45 ounces of gold per ton). Stamp tailings were being collected in a settling pond since they contained approximately $4.00 gold per ton (0.20 

ounces of gold per ton) (Stewart, 1922). 

 Production records indicate that by 1933 this mine had produced 13,560 troy ounces of 

gold from 8,200 tons of ore with an average grade of 1.65 ounces of gold per ton (Hill, 

1933). In August of 1933, a rich ore shoot was discovered in the Upper adit on the Helen 

S claim. Between August 1933 and June, 1934, this shoot produced 3,010 ounces of gold 

from material grading 2.1 ounces of gold per ton (Joralemon, 1934). 

 In the fall of 1941, a 2-foot-wide stibnite pod was re-discovered on the Antimony shear 

zone approximately 600 feet north of the Main adit portal. This material contained 60 to 

66% antimony with 0.01 ounces of gold per ton and 1 ounces of silver per ton (Joesting, 

1942; ATDM Pamph. 1). Approximately 15 tons of this material had been identified in 

surface pits by 1942 (Joesting, 1943). 

 Fairbanks Exploration Inc. conducted limited sampling of the Hi-Yu mine waste dumps 

and stamp sand tailings ponds in 1986 (Fairbanks Exploration Inc., unpublished report, 

1986). Waste dump material from both levels of the mine indicate that the mineralization 

is hosted by siliceous exhalite, metarhyolite tuff, and black carbonaceous quartzite of the 

Cleary Sequence. Mineralization consists of fine-grained, stratiform arsenopyrite and pyrite in metavolcanic lenses with stibnite-pyrite mineralization in pelitic host rock. Intense 

argillic alteration is all but destroyed by the nearly complete supergene alteration present 

on most samples. Samples collected from the Main adit dump contained gold values 

ranging from 260 to 3200 ppb and were associated with highly anomalous arsenic, antimony and silver (Fairbanks Exploration Inc., unpublished report, 1986). Samples collected from the stamp mill tailings pond below the mill contain highly anomalous gold (to 

1.701 ounces of gold per ton), silver (to 6.14 ounces of silver per ton), arsenic and antimony, all of which appear to be concentrated in sulfide-rich lenses in the stamp sands 

(Fairbanks Exploration Inc., unpublished report, 1986). Gold values in stamp sands from 

the Hi-Yu mill indicate that a significant proportion of the gold in the Hi-Yu ores is contained in the -30 mesh size range. 

 In 1988, Tri-Con Mining reportedly mined 14,600 tons of material from the Hi Yu mine 

stamp-tailings dump and the American Eagle mine waste dump. The average gold grade 

mined was 0.10 ounces of gold per ton (Freeman, 1992). Tri-Con Mining removed all of 

the mineable stamp sands in the Hi Yu dump.

Workings/exploration:

 The Hi-Yu lode was discovered in 1912 (Times Publishing Company, 1912). Initial development began on the Helen S claim, and by 1913 the Main adit was 450 feet long with 

a 65 foot raise connected to the surface approximately 250 feet from the portal. A second 

adit, 50 feet below the Main adit, known as the Lower adit, was collared in 1913. In 

1914, the Main adit was lengthened to 550 feet and the Lower adit driven 450 feet 

(Stewart, 1922). By the end of 1915, the Main adit had been driven to a total length 700 

feet and the Lower adit remained 450 feet in length. By 1916, the Lower adit had been 

abandoned and a new adit, the Hi-Yu adit, was collared on the Hi-Yu claim approximately 500 feet above the level of Moose Creek (Stewart, 1922). By 1920 the Hi-Yu adit 

had been driven 1,300 feet. A raise connected the Hi-Yu adit with the surface at the 800 

foot station of the adit (Stewart, 1922). 

 By the end of 1922, the Hi-Yu mine had stoped out all of the ore on the Helen S claim 

between the Lower and Main adits from the portal for a distance of 400 feet. Similarly, 

all of the ore had been stoped out between the Main and Upper adits for a distance of 800 

feet from the portal. The Main adit was extended to a length of 1,000 feet and the Upper 

adit, located 175 feet above the Main adit, was 40 feet deep. On the Hi-Yu claim, all of 

the ore had been stoped out between the Hi-Yu adit and the surface for a distance of 1,100 

feet from the portal except for a block 150 feet long near the middle of the adit (Stewart, 

1922). The branch tunnel in the Hi-Yu adit was extended to a depth of 200 feet from the 

Hi-Yu tunnel. Stamp tailings were being collected in a settling pond since they contained 

approximately $4.00 per ton in gold (0.20 ounces of gold per ton) (Stewart, 1922). 

 Stewart (1923) reported the Upper adit on the Helen S claim had been extended to a 

length of 600 feet by 1923. This adit level is approximately 125 feet below the level of 

the Hi-Yu adit on the Hi-Yu claim. In addition, the Lower adit on the Helen S claim was 

extended to a length of 500 feet. In 1931 a raise was being driven between the Main adit 

and Upper adit (Smith, 1933; Smith, 1933, B 844; Stewart, 1933). In 1932, the Upper 

adit was 1,200 feet long and the Main adit was 1,525 feet long (Pilgrim, 1933). Patty 

(1933) indicated the Upper adit on the Helen S claim was 1600 feet long in early 1933. 

The Upper adit was 1,875 feet long in 1934. A cross-cut was being driven from the Upper adit in 1934 to intersect the Antimony shear zone, a 4-foot-wide shear zone reportedly 

averaging 0.5 ounces of gold per ton. In 1938, the Hi-Yu mine completed 300 feet of 

drifting and 250 feet of raises on the Lower adit level and in sublevels between the Lower 

and Main adit levels. 

 In 1984, Placid Oil Company conducted dozer trenching and drilled a total of 8,205 feet 

in 19 diamond core holes (Porterfield and Croff, 1986). Additional diamond core drilling 

in 1985 on the Hi Yu shear consisted of 2 holes (515 feet) on the Hi Yu shear zone. Fairbanks Exploration Inc. conducted limited sampling of the Hi Yu mine waste dumps and 

stamp sand tailings ponds in 1986 (Fairbanks Exploration Inc., unpublished report, 1986). 

During July, 1988, a total of 27 stamp sand samples were collected from the Hi Yu mine 

tailings dump (Fairbanks Exploration Inc., unpublished report, 1988). The Hi Yu mine 

workings are currently inaccessible but the ten stamp mill and powerhouse are still standLG182

ing and in excellent condition. 

Production notes:

 The Hi-Yu mine, also known as the Crites and Feldman mine, was the second largest 

lode gold producer in the Fairbanks District. By September 1914, the mine was in full 

production, milling an average of 7 tons of ore per day, primarily from the Lower adit 

(Stewart, 1915; Brooks, 1916). By 1916, the Hi-Yu mine had replaced the Cleary Hill 

mine as the largest producer in the Fairbanks Mining District. The mine continued to be 

the largest producer in the district from 1924 to 1926 (Brooks and Capps, 1924; Brooks, 

1924; Moffit, 1927). Smith (1930) reported primarily development work at the mine in 

1927, but significant production was again reported in 1928 and 1929 (Smith, 1930; 

Smith, 1932). There was no production reported in 1930 and the mine was not in operation for most of 1931. During the winter of 1932-33 over $100,000 worth of gold (4,837 

ounces) was produced from stopes above the Upper adit. Production records from the HiYu and Helen S shear zones provided by the owners in 1933, indicate production of 

13,560 troy ounces of gold from 8,200 tons of ore with an average grade of 1.65 ounces 

of gold per ton (Hill, 1933). In August of 1933, a rich ore shoot was discovered in the 

Upper adit on the Helen S claim. Between August 1933 and June, 1934, this shoot produced 3,010 fine ounces of gold from material grading 2.1 ounces of gold per ton 

(Joralemon, 1934). The Hi-Yu mine remained the second largest producer in the Fairbanks Mining District during 1936, 1937 and 1938 (Smith, 1938; Smith, 1939, B 910; 

Smith, 1939, B 917). In 1938, the mine produced 2,500 tons of ore which averaged $24 

per ton in gold (0.68 ounces of gold per ton) (Reed, 1939). The mine recorded continuous production in 1939 and 1940 (Smith, 1941; Smith, 1942). Killeen and Mertie (1943) 

reported that the Hi-Yu mine was shut down in 1942 by the War Production Board Order 

L208, and like most other mines in the district, the Hi-Yu mine did not reopen after 

World War II. Existing records indicate the Hi-Yu mine produced approximately 22,161 

ounces of gold between 1933 and 1941 (E. Brandell, written commun., 1949). In 1988, 

Tri-Con Mining reportedly mined 14,600 tons of material from the Hi-Yu mine stamp 

sand tailings dump and the American Eagle mine waste dump. The average gold grade 

mined was 0.10 oz/ton gold (Freeman, 1992). Mining conducted by Tri-Con Mining removed all of the mineable stamp sands in the Hi-Yu dump site. 

Reserves:

 Ore reserve estimates of the Hi Yu mine waste dumps are limited to the Main adit dump 

where sampling conducted in 1986 indicated 34,530 tons grading 0.397 ounces of gold 

per ton and 1.60 ounces of silver per ton. However, these estimates are not representative 

of the true grades in the dumps since 1986 sampling was restricted to material with visible metallic sulfide or oxide mineralization. The true grade of the Hi Yu waste dumps is 

suspected to range from 0.05 to 0.10 ounces of gold per ton (Freeman, 1992).

Geologic description:

 Except near the mouth and the extreme headwaters of this placer-mined creek, the bedrock is shale, tuff and diabase of the Rampart series (Spurr, 1898). Prindle and Hess 

(1906) describe the bedrock as slate near the head, quartzite with tuffaceous greenstone in 

the lower part of the valley, and Kenai (Tertiary) sandstone and conglomerate near the 

mouth. More recent geologic mapping of the area indicates that most of the Hunter Creek 

drainage is underlain by mafic igneous rocks with a few interlayered sedimentary rocks 

(Weber and others, 1992). Prospectors found gold through the entire length of the creek 

(Spurr, 1898). 

 Gravels are 2 to 12 feet thick and overlain by as much as 40 feet of frozen muck 

(Prindle and Hess, 1906). Much of the gold was found in bedrock cracks along with considerable barite and some hematite in the concentrates (Prindle and Hess, 1906). Eakin 

(1912) reported that there was very little production from stream gravels and that most 

gold came from the bench 15 to 20 feet above the stream. The bedrock surface was noted 

to be uneven with overburden thickening toward the valley wall (Eakin, 1912). The 

gravel and the top 4 feet of shattered greenstone bedrock were mined (Mertie, 1934). 

Heavy mineral in concentrates include magnetite, ilmenite, hematite, barite, pyrite, picotite, cinnabar, galena, cassiterite, and native copper (Mertie, 1934). Waters (1934) reported that concentrate samples also contained garnet, zircon, limonite, quartz, diopside, 

and epidote.

Geologic description:

 Coarse and shotty gold occurs in high Pliocene (?) gravels about 1,000 feet higher than 

the mouth of Little Minook Creek (Mertie, 1934). A shaft at the crest of the ridge is said 

to have been sunk 100 feet to bedrock (Mertie, 1934). Coarse gravels contain quartzite, 

quartzite breccia, vein quartz and chert (Prindle and Hess, 1905). Heavy minerals include 

ilmenite, hematite, and magnetite (Mertie, 1934). Although there was not enough water 

for large-scale mining, prospecting and drift mining occurred in 1913, the late 1920's and 

the 1930's (Cobb, 1976; OFR 76-633, p. 102). Some work was reported as late as 1975

is 6 feet wide at the surface and steepens to vertical at 100 feet. By October 1912, a second shaft, located 100 feet northwest of the old shaft, was down 20 feet. The shear contained free-milling gold but no assay information is available. By 1913, this prospect 

consisted of a short shaft and a 100-foot inclined shaft with an 18-inch-wide quartzbearing shear zone exposed about 30 feet from the top of the incline. This shear is cut off 

by a fault striking N 70 W and dipping 33 NE (Chapin, 1914). The fault cuts the shear at 

a low angle and was followed by the incline to its full 100 foot depth. The prospect was 

not being explored in 1913 and no information is available on the grade or character of

Geologic description:

 Gold was found in a 12- to 13-foot-wide vertical shear zone striking N 40 E; it contained highly fractured quartz. Mineralization is along the margin of the vein and along 

fragments of schist in the vein (Prindle, 1910, p. 227). 

 The original prospect consisted of three claims: the Lemon, Lime and North Star 

claims (Prindle, 1910). By 1909, a 120-foot-long adit had been driven parallel to the shear 

and a cross-cut had intersected the shear zone approximately 50 feet below surface. Samples collected from the site panned $40 gold per ton in free gold (1.9 ounces of gold per 

ton); they were from the six-inch-wide, high grade portion of the shear. The remainder 

panned approximately $2 gold per ton in free gold (0.09 ounces of gold per ton) (Times 

Publishing Company, 1912). Two other parallel quartz-bearing shear zones were known 

to exist but had not been explored in 1909. Smith (1913, B 525) reported the prospect 

was inactive in 1912 by which time the adit was 150 feet long (Times Publishing Company, 1912). By 1913 the adit had been extended to 160 feet in length and several crosscuts driven to explore the shear zone (Brook, 1914).

Geologic description:

 By 1911, the prospect had a 40-foot deep shaft on an 18-inch-wide quartz and base 

metal-bearing shear zone that trended northwest, and dipped 45 NE (Times Publishing 

Company, 1912; Brooks, 1911). The surface width of the shear was 8 feet. Another 

shear zone, was traced for 1,500 feet in pits no more than 12 feet deep. One ton of material mined from the Charles prospect in 1911 averaged $25 gold per ton (1.2 ounces of 

gold per ton) in free milling gold (Times Publishing Company, 1912). The one ton sample was extracted from a high grade portion of the shear which averaged 10 inches in 

width. 

 Burand (1968) notes that work had been conducted on a lead-silver prospect in upper 

Walnut Creek and it is believed this reference was to the Charles prospect. Samples of 

shear zone quartz collected by Pilkington and others (1969) from the Eleanor claim area 

on the northwest end of the Charles prospect ranged from 1.95 to 43.5 ppm gold (0.057 to 

1.27 ounces of gold per ton). A sample of mineralized schist from this same area contained 1.27 ppm gold (0.037 ounces of gold per ton). 

 In 1976 and 1977, prospect owners Richard Griff and James Madonna conducted dozer 

trenching and drilled three 80-foot holes (L. Katkin, written commun., 1978). Samples 

contained 0.037 to 1.969 ounces of gold per ton, 0.12 to 57.84 ounces of silver per ton, 

0.02 to 15.9% lead, from a trace to 2% antimony, and traces of copper and zinc. 

 The prospect was remapped and sampled in 1980; the work revealed two sub-parallel, 

LG192 
Alaska Resource Data File 

Page 433 

N 60-80 W trending shear zones approximately 800 feet apart (Blakestad, 1980). The 

lower of these two zones ranged from 2 to 12 feet wide and contained quartz-stockwork 

shear zones up to several feet thick in the most intensely sheared areas. Gold, stibnite and 

galena were identified on the lower zone. The upper zone was hosted in maripositebearing schist and ankerite-bearing quartz-mica schist with conformable oxidized and 

leached zones stained by scorodite and cervantite. Scheelite was identified on one siliceous unit in the upper zone. Limited sample results from Blakestad (1980) indicated the 

prospect has a high lead and silver content. 

 Reconnaissance-scale soil sampling in the Charles area was conducted in 1997 and expanded in 1998 (Freeman and others, 1998). Trenching was completed in the Charles 

area subsequent to the 1997 soil sampling program and returned sporadic high-grade gold 

associated with antimony and arsenic, but did not outline contiguous intervals of significant gold mineralization. Both upper and lower plate lithologies were encountered in 

trenches and higher gold values are more common in rocks containing abundant iron- and 

manganese-oxides. Three reverse-circulation holes were drilled in the Charles area during 1998 to target anomalous gold, arsenic, antimony, bismuth, and tellurium values in 

soils. The primary target in this area was the down-dip extension of a flat-lying crushed 

quartz vein zone exposed in an old trench east of the Charles Shaft. The drill hole intersected crushed quartz of only moderate grades, 0.102 ounces of gold per ton over five 

feet.

Location description and accuracy:

 Cobb (1972, MF-413), loc. 55; NW1/4 sec. 9, T. 3 N., R. 3 E., of the Fairbanks Meridian. This prospect is located near the confluence of the two headwater forks of Kokomo 

Creek at an elevation of about 1,500 feet. It is approximately 1 mile north of Coffee 

Dome. Accuracy is within 2,000 feet.

Geologic description:

 By 1931, several hand trenches exposed four or five quartz-bearing shear zones approximately 100 feet apart (Hill, 1933). The shear zones trend N 40 W and dip 45-60 SW 

The prospect is hosted in flat-lying biotite schist. One shear consists of an 8-foot-thick 

zone of mixed schist and quartz although most of quartz-rich portions are 1 to 2 feet wide. 

A 20-inch-wide quartz shear zone contained 0.36 ounces of gold per ton. In 1938, two 

15-foot shafts were sunk on the prospect but no information about these shafts is known 

(Reed, 1939). Placer gold was produced from Kokomo Creek below the Egan prospect 

but its relationship to mineralization on the Eagan prospect is unknown (Burand, 1968).

Geologic description:

 Fairbanks Creek is one of the major placer creeks in the Fairbanks mining district. It 

has been mined almost continuous for a distance of 8 miles from the McCarty Mine 

(ARDF no. LG152) to the Fish Creek flats near the mouth of Clark Creek. 

 Bedrock is mainly schist, from 15 to over 110 feet deep (Cobb, 1976). The gravels are 

schist, vein quartz and some gneiss. Minerals in concentrates include gold, wolframite, 

cassiterite, rutile, stibnite, and scheelite (Cobb, 1976; OFR 76-633). 

 U.S.S.R. & M. Co. (F.E. Co.) operated Dredge no. 2 on Fairbanks Creek from 1950 

through 1961 (R.M. Chapman, 1978, unpublished U.S.G.S. memorandum). Cook's Mining has been actively mining Fairbanks Creek throughout the 1980's and 1990's, and has 

mined to within approximately 200 yards of the McCarty mill at the head of the creek (J. 

Schaefer, field observation, 1999). Cook's Mining was not active in the creek when visited in 1999 (J. Schaefer, field observation, 1999).

operated Dredge no. 2 on Fairbanks Creek from 1950 through 1961 (R.M. Chapman, 

1978, unpublished U.S.G.S. memorandum). Cook's Mining has been actively mining 

Fairbanks Creek throughout the 1980's and 1990's, however, they were not active in the 

creek when visited in 1999 (J. Schaefer, field observation, 1999). 

Production notes:

 Placer mining from 1903 to present. Dredging began in 1911, but drift and other mining also continued. Production, including that from tributaries, from 1903 through 1920 

was about 380,115 fine ounces of gold (Cobb, 1976; OFR 76-633, p. 63). In the 1980's 

and 1990's, Cook's Mining produced an unreported amount from Fairbanks Creek.
