Site type: Mine 

ARDF no.: SR002 

Latitude: 60.8623 Quadrangle: SR D-7, D-8 

Longitude: 149.6060 

Location description and accuracy:

 Resurrection and Palmer Creeks are located in T. 8 and 9 N., R. 2 W., of the Seward Meridian. The map 

site representing this placer mine is in the NE1/4 section 22, T. 9 N., R. 2 W. Resurrection Creek flows 

north into Turnagain at the town of Hope. Palmer Creek is a tributary of Resurrection Creek and flows 

west. The productive portion of Resurrection Creek is from its junction with Palmer Creek to Turnagain 

Arm (Seward D-8 quadrangle). Palmer Creek was most productive near its junction with Resurrection 

Creek (Seward D-7 quadrangle). This is location 138 of Cobb and Richter (1972), locations 163, 182, and 

183 of MacKevett and Holloway (1977), location 11 and 12 of Cobb and Tysdal (1980), and location P-90 

of Jansons and others (1984).

Geologic description:

 Resurrection Creek flows north through a broad valley 21 miles long, floored with a thick deposit of gravels. Throughout the greater part of its length, the stream has incised a deep canyon-like channel. Near the 

lower end of the valley, the stream flood plain widens, and a short distance below the mouth of Palmer 

Creek, it is 1,000 feet wide. High bench gravels flank both sides of flood plain. 

 Bedrock in this drainage is sedimentary rock of the Valdez Group of Late Cretaceous age (Nelson and 

others, 1985). Gravels consist of sandstone, slate, minor conglomerate, granite, and a little clayey matrix 

(Cobb and Tysdal, 1980). Boulders as much as 3 feet wide are common, and locally some are much larger. 

Graywacke boulders predominate, while granite and conglomerate boulders are much less abundant. The 

average thickness of the productive gold-bearing gravels, which rest on a bluish-yellow clay so-called bedrock, is 7 feet (Johnson, 1912). Production grades of 0.01 ounce of gold per cubic yard of gravel have 

been reported, along with locally higher grades. The gravel below the clay is barren (Tuck, 1933). In a 

few places the gravel is slightly consolidated and boulders as large as 4 feet in diameter are common. 

 Upper Palmer Creek flows 6 miles through a fairly broad valley filled with avalanche and glacial debris, 

including large boulders. Lower Palmer Creek occupies a narrow canyon cut partly in bedrock and partly in 

gravel terraces associated with Resurrection Creek (Moffit, 1906). Bedrock in the Palmer Creek drainage is 

graywacke and slate of the Valdez Group (Nelson and others, 1985). The gravels are derived from the country rock, although there are a few granitic boulders that may not be of local origin. The gravels are largely 

angular and coarse, containing 5 percent or more of boulders that are more than18 inches in diameter 

(Moffit, 1906). Below the surface, the gravels are roughly stratified, but at the surface they are irregularly 

distributed. Some 30 to 40 percent of the gold that has been recovered lay on bedrock surface (Moffit, 

1906). The gold is coarse, typically flattened, and smooth. Most of the gold is bright yellow, but some is 

whitish. Native silver nuggets weighing as much as a pennyweight have been reported, in addition to a little 

black sand.

Workings/exploration:

 Operations on Resurrection and lower Palmer Creeks begin in 1888. Extensive hydraulic and hand placer 

mining began in 1895 and continued intermittently into the 1950's (Jansons and others, 1984). There was an 

unsuccessful attempt to use a hydraulic elevator on Resurrection Creek, which failed due to lack of water 

and to an abundance of large boulders (Moffit, 1906). A five-foot Risdon open-connected dredge was installed in 1905 but was unsuccessful due to the shallowness of the ground and the presence of large boulders 

(Johnson, 1912). Mechanized mining replaced hydraulic mining in the 1960's. Mechanized mining on 

Hope Mining Company claims occurs intermittently up to the present (2000) (C. S. Huber, oral communication, 2000). 

 Considerable recreational mining currently (2000) occurs on Resurrection Creek below Palmer Creek in 

an area known at the old St. Louis mining claims. This mining consists of panning, sluicing, and small-scale 

suction dredging. Within the St. Louis claim block is the Paystreke, a patented claim. The Paystreke currently serves as a tourist attraction and offers gold panning (C. S. Huber, oral communication, 2000). 

 The U.S. Bureau of Mines has sampled Palmer Creek. Their pan samples contained traces of gold 

(Jansons and others, 1984). 

 Mining on Palmer Creek, has been confined primarly to channel gravels, chiefly in the lower 1.5 miles 

(lower canyon area) (Moffit, 1906). Two hydraulic plants were at work in 1904, employing about 10 men 

(Moffit, 1906). The efficiency of these plants was hampered by the large number of boulders that required 

removal by hand. Probably less than 100 yards a day was moved by either of these plants (Moffit, 1906). 

 Palmer Creek gold is coarse and typially much flattened and smooth. Native silver is present in some deposits (Moffit, 1906). Some small-scale suction dredging is taking place on lower Palmer Creek (C. S. 

Huber, oral communication, 2000). 

Production notes:

 The U.S. Bureau of Mines has estimated total gold production since 1895 to be 30,000 to 40,000 ounces, 

of which approximately 2,000 to 3,000 ounces have been produced since 1980 (Jansons and others, 1984). 

Production grades of 0.01 ounce of gold per cubic yard have been reported, but higher grades occur locally 

(Jansons and others, 1984). 

 Stream gravels mined in the early 1900's on lower Palmer Creek, reportedly yielded about $1 per yard 

(gold at $20.67 per troy ounce), but 30 to 40 percent of the gold lay on the bedrock surface (Tysdal, 1978 

[MF-880-B]). 

Reserves:

 The U.S. Bureau of Mines has estimated the inferred placer gold reserve base for Resurrection-Palmer 

Creeks at greater than 2,000,000 cubic yards (Jansons and others, 1984).

Site name(s): Bear Creek 

Site type: Mine 

ARDF no.: SR004 

Latitude: 60.9135 Quadrangle: SR D-7 

Longitude: 149.5878 

Location description and accuracy:

 Bear Creek is mainly in T. 10 N., R. 2 W., of the Seward Meridian. From its headwaters, it flows about 5 

miles north into Turnagain Arm near the town of Hope. The map site of this placer mine is in the SW 1/4 

section 35, T. 10 N., R. 2 W., of the Seward Meridian. This is location 139 and 140 of Cobb and Richter 

(1972), location 5 and 164 of MacKevett and Holloway (1977), location 10 of Cobb and Tysdal (1980), and 

location P-91 of Jansons and others (1984). 

Commodities: 

 Main: Au 

 Other: Ag, Cu 

Ore minerals: Copper, gold, silver 

Gangue minerals: 

Geologic description:

 Bear Creek drains an area underlain by graywacke and slate of the Valdez Group of Late Cretaceous age 

(Nelson, 1985). The beds strike N20E or nearly at right angles to the general course of the creek, whereas 

the cleavage strikes more nearly north (Martin and others, 1915). At the head of the creek there are numerous felsic dikes that trend in all directions, unlike those in other parts of the district, which generally trend 

north (Tuck, 1933). 

 The stream and bench gravels are very irregular in distribution. They consist almost entirely of the local 

bedrock, but also include granitic boulders. In two places, 25 to 30 feet of unstratified alluvium contains a 

large quantity of large, angular blocks mixed with sand and clay. Boulders 3 to 4 feet in diameter are common. In some places the surface wash is underlain by stratified sand and clay, which were probably deposited in small local basins where they in places abut against perpendicular rock faces or overlap sloping surfaces. The hard gray (so-called) glacial clay locally underlies the surface wash and rests on loose sand 

composed largely of slate particles. The clay contains a large amount of water (Martin and others, 1915). 

The lower portion of the creek flows over an alluvial fan consisting of fairly well sorted and washed gravels. 

 Some of the gold occurs on false bedrock. Both the creek and bench gravels are auriferous (Cobb and 

Tysdal, 1980). Gold is fairly coarse, yielding nuggets as heavy as 10 ounces (Jansons and others, 1984). 

Besides gold, native silver nuggets have been found, as well as a small amount of native copper (Moffit, 

1906).

Production Status: Yes 

Site Status: Active 

Workings/exploration:

 Mining began on Bear Creek in 1894. Early mining was by pick and shovel. Hydraulic mining was done 

in 1904 (Moffit, 1906), but was difficult because of the presence of large boulders. These boulders were 

removed from the pit by derrick or cableway and were dumped along one side of the channel. This process 

was costly and time-consuming (Moffit, 1906). 

 The U.S. Bureau of Mines collected a surface sample of channel gravel in upper Bear Creek; it contained 

0.0021 ounce of gold per cubic yard (Jansons and others, 1984). In 1994 or 1995, a 28-ounce nugget was 

recovered from the Tabatha mining claim (C. S. Huber, oral communication, 1999). Hand mining and suction dredging was still taking place in 2000. 

Production notes:

 The U.S. Bureau of Mines estimated production since 1894 at 4,000 to 6,000 ounces of gold, of which 

less than 1,000 to 1,500 ounces have been produced since 1975 (Jansons and others, 1984). 

Reserves:

 The U.S. Bureau of Mines estimated that there is greater than 3,000,000 yards of auriferous gravels in the 

Bear Creek drainage (Jansons and others, 1984).

bed of the creek, it could not be developed by drifting. Therefore, the adit was driven through slide material 

in hopes of reaching the vein, but bedrock was never encountered (Tuck, 1933). There are no reported production or assay results. The U.S. Bureau of Mines visited the prospect in 1981, but the adit was inaccessible and no samples were collected (Jansons and others, 1984).

Location description and accuracy:

 The prospect is located in the SW1/4 section 1, T. 8 N., R. 2 W., of the Seward Meridian. It is situated 

500 to 1,500 feet west of the Palmer Creek road, at an elevation of 2,050 to 3,050 feet. It is mislocated on 

the Seward D-7 topographic map. This is location 10 of Cobb and Richter (1972), location 9 of MacKevett 

and Holloway (1977), location 21 of Cobb and Tysdal (1980), and location S-293 of Jansons and others 

(1984). The location is accurate to within 300 feet. 

Commodities: 

 Main: Ag, Au

Ore minerals: Chalcopyrite, gold, pyrite 

Gangue minerals: Quartz 

Geologic description:

 The deposit at the prospect consists of two principal quartz veins and some small seams of quartz. The 

veins are in massive graywacke of the Valdez Group of Late Cretaceous age that is cut by several thrust 

faults (Tuck, 1933; Nelson and others, 1985). The thrust faults are located about 40 feet from the portal at 

the 2,700-foot level, trend N20E, and dip 15-30W. The faults contain from 2 to 8 inches of gouge in which 

there are small seams of quartz that carry visible gold. The vein that has received the most attention is at an 

elevation of 2,700 feet. It ranges from 6 to 12 inches wide, strikes generally east-west, and dips almost vertically. The other vein is 2 to 12 inches wide, horizontal, and intersects the first vein at the 2,700-adit level. 

Both veins have very tight walls and appear to be localized by originally small fractures along which quartzbearing solutions replaced the country rock. The replacement is irregular; in places the veins lose their planar form, and the quartz occurs in irregular masses (Tuck, 1933). Both veins carry small amounts of chalcopyrite, pyrite, and gold.

Workings/exploration:

 Tuck (1933) reported one 130-foot adit at an elevation of 2,700 feet. The U.S. Bureau of Mines reported 

three adits, at elevations of 2,050, 2,700, and 3,050 feet (Jansons and others, 1984). The lower level is 

caved at the portal, the middle level is reported to be 300 feet long and is caved 75 feet from the portal, and 

the upper level is accessible and 130 feet long. There are several prospect pits nearby. 

 The U.S. Bureau of Mines examined the prospect in 1980 and collected two grab samples and four chip 

samples. The grab samples assayed trace amounts of gold and a trace to 0.01 ounce of silver per ton. Four 

chip samples from the 130-foot-long adit assayed from nil to 0.73 ounce of gold per ton and nil to 0.3 ounce 

of silver per ton (Jansons and other, 1984). 

Production notes:

 An unpublished report of the U.S. Bureau of Mines, date unknown, referenced in Hoekzema and Sherman 

(1983) reported 347 ounces of gold, but Jansons and others (1984) indicated no production. It is likely that 

the published report is the accurate one. 

Reserves:

 The U.S. Bureau of Mines estimated 350 tons at 0.1 ounce of gold per ton (Jansons and others, 1984).

Location description and accuracy:

 The mine is located in the NW1/4 section 24, T. 8 N., R. 2 W., of the Seward Meridian. The mill site is 

located on the east side of Palmer Ceek near the head of Palmer Creek valley, at an elevation of 2,200 feet. 

The mine workings are located about three-fourths of a mile south of the mill site at between 3,200 and 

3,400 feet elevation. This is location 12 of Cobb and Richter (1972), location 11 of MacKevett and Holloway (1977), location 24 of Cobb and Tysdal (1980), and location S-289 of Jansons and others (1984). This 

location is accurate to within 300 feet. 

Commodities: 

 Main: Au 

 Other: Ag, Cu, Pb 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, sphalerite 

Gangue minerals: Ankerite, calcite, quartz 

Geologic description:

 The country rock in this area is slate of the Valdez Group of Late Cretaceous age (Nelson and others, 

1985). The slate strikes N35E and dips 60-80E. Near the surface the slate dips as low as 40E due to surface 

creep. Bedding in the slate is not visible underground (Hoekzema and Sherman, 1983). 

 The underground workings consist of three levels at vertical intervals of 100 feet. The upper adit is about 

30 feet below the discovery outcrop and is collapsed. This adit was about 350 feet in length. The middle 

adit was about 500 feet long; it is unsafe to enter because the ground above and below the adit has been stoped out. The lower adit was about 600 feet long and is collapsed about 100 feet from the portal (Hoekzema 

and Sherman, 1983). 

 The deposit consists chiefly of an auriferous, sulfide-bearing, quartz-carbonate vein. Parts of the vein are 

oxidized and sheared. The vein occurs in a curving and branching fracture that cuts perpendicularly across 

the cleavage of the slate, so that the strike of the vein ranges from N45W to west. The dip of the vein 

ranges from 20N on the west end of the middle level to 75NE on the east end of the middle level. The average dip is about 40N. The width of the vein ranges from a few inches to 5 feet and averages about 18 

inches. On the lower level the vein is about 300 feet long, but only locally contains ore minerals. On the 

middle level, the vein is 350 feet long; the vein is shorter on the upper level due to the slope of the hill 

(Tuck, 1933). The vein contains considerable fault gouge and, in part, consists of breccia that has been 

healed by quartz. Considerable post-mineral movement has taken place; most of the movement is parallel 

to the vein margins. The margins of the vein are clearly defined, and the quartz breaks cleanly from the 

sheared slate (Tuck, 1933). 

 The mineralolgy of the vein consists of quartz along with small amounts of calcite and ankerite. The metallic minerals, in order of abundance, are arsenopyrite, pyrite, galena, sphalerite, chalcopyrite, and free 

gold. Arsenopyrite is by far the most abundant sulfide. The porportion of sulfide to quartz varies greatly 

from place to place, ranging from less than 1 percent to more than 20 percent (Tuck, 1933). There does not 

appear to be a direct relation between sulfide content and gold grade. In fact, the richest gold ore appears to 

have the lowest sulfide content (Tuck, 1933). The gold is almost entirely in the principal vein. In some of 

the richer parts of the mine, other veins in the wallrock may carry some gold, but not enough to warrant 

SR011

mining. Assays were as high as several hundred dollars in gold per ton (gold at $20.67 per ton). The upper 

portion of the mine was rich enough to make a profit using a one-stamp mill. In general, the oxidized and 

sheared quartz, which can easily be identfied by eye, carries the highest values (Tuck, 1933).

Production Status: Yes; small 

Site Status: Inactive 

Workings/exploration:

 The deposit that became the mine was discovered in 1911 by John Hirshey. A one-stamp mill was built 

on the site, and the mine operated from 1911 to 1921, when it was sold to the Anchorage Mining Company. 

In 1921, a road was built from Hope to the mine site, and a new plant consisting of a jaw crusher, a fivestamp mill with amalagator plate, and a Wilfley table was built. The mine was productive until 1927, when 

it reverted back to John Hirshey, who sporadically mined until 1940. In 1931 a cyanide plant was used to 

rework tailings but was unsuccessful (Tuck, 1933). There has been no further production since 1940. 

 The underground workings consist of three levels at vertical intervals of 100 feet. The upper adit is about 

30 feet below the discovery outcrop and is collapsed. This adit was about 350 feet in length. The middle 

adit was about 500 feet long; it is unsafe to enter as the ground above and below the adit has been stoped 

out . The lower adit was about 600 feet long and is collapsed about 100 feet from the portal (Hoekzema and 

Sherman, 1983). 

Production notes:

 Total production from this mine is 6,094 ounces of gold and 4,699 ounces of silver from about 8,706 tons 

of ore (Hoekzema and Sherman, 1983). 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 2,000 tons with an estimated grade of 1 to 1.25 ounces 

of gold per ton and 0.65 ounce of silver per ton (Hoekzema and Sherman, 1983). 

Additional comments:

 Tuck (1933) stated that the vein continued below the lower level, but the deposit has never been drilled 

below the lower working. In addition, the 0.3 ounce of gold per ton cut-off grade in the old workings suggests that a potential gold resource may remain.

Geologic description:

 The deposit is in a fractured Eocene(?) felsic dike that strikes N15E and dips 65SE. Fractures in the dike 

are filled with quartz-calcite veins containing arsenopyrite, chalcopyrite, galena, sphalerite, and minor gold. 

In some parts of the dike, quartz may be absent; in other parts it may constitute as much as 30 percent of the 

dike. The width of the dike varies from 1 to 8 feet. It averages 2.5 feet wide and is traceable for as much as 

4 miles along strike (Tuck, 1933). The dike is commonly offset by right-lateral transverse faults having 

typical displacements of less than 20 feet. The dike is hosted by slate and graywacke of the Upper Cretaceous Valdez Group (Tysdal, 1978 [MF-880-A]).

traces of gold and silver. Nevertheless, Tuck (1933) reported that small flakes of free gold could commonly 

be seen in the vein material in the dike. 

 The U.S. Bureau of Mines collected a chip sample and a grab sample of the dike in 1982. The chip sample assayed a trace of gold and silver. The grab sample assayed 0.117 ounce of gold per ton and 0.2 ounce 

of silver per ton (Jansons and others, 1984). The Bureau suggested that large reserves are possible but that 

the grade appears to be less than 0.05 ounce of gold per ton.

Geologic description:

 The principal deposit at this mine consists of two sulfide-bearing, quartz-carbonate veins in sheared slate 

and graywacke of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]). The host rock is 

primarily slate whose foliation strikes north and dips 55E. 

 One vein is 2 to 10 inches wide, strikes N28E, dips 67W, and can be traced for 120 feet along strike in the 

upper level drift. This vein pinches and swells along a 1- to -3-foot -wide shear zone and is bounded by 

considerable fault gouge along both walls. Metallic minerals include arsenopyrite, galena, sphalerite, and 

gold (Hoekzema and Sherman, 1983). 

 The other vein is 3 to 24 inches wide, strikes N35W, dips 35NE, and is exposed at the upper portal and in 

a trench extending northwesterly from the portal. Metallic mineral include arsenopyrite, pyrite, galena, 

sphalerite, and gold. Several other northwest-trending veins occur in the area, but they appear to be less 

mineralized (Hoekzema and Sherman, 1983). The deposit has been isotopically dated at 53.2 +/- 1.6 million years (Eocene) (Mitchell and others, 1981).

 Workings consist of two adits and five open cuts. The upper-level adit, at 3,000 feet elevation, is a 290-

foot drift, and the lower-lever adit at 2,920 feet elevation, is 350 feet long. There are 120 feet of trenching 

and a 30-foot horizontal cut (Jansons and others, 1984). A test shipment was reported to assay 2.3 ounces 

of gold per ton (Roehm, 1937 [PE 95-11]). Improvements consisting of a bunkhouse, blacksmith shop and 

equipment were destroyed by an avalanche in 1941 (see Roehm references). 

 Both adits were accessible in 1982, when the U.S. Bureau of Mines examined and sampled the property 

(Hoekzema and Sherman, 1983). Four chip samples collected by the Bureau assayed from 0.07 to 28.08 

ounces of gold per ton and less than0.2 to 9.3 ounces of silver per ton. Reserves are estimated at 500 tons 

of ore at a grade of 0.5 ounce of gold per ton and 0.3 ounce of silver per ton (Jansons and others, 1984). 

Production notes:

 Recorded production is 408 ounces of gold and 24 ounces of silver (Jansons and others, 1984). 

Hoekzema and others (1983) reported the recorded production is 94 ounces of gold. 

Reserves:

 Reserves are estimated at 500 tons of ore at a grade of 0.5 ounce of gold per ton and 0.3 ounce of silver 

per ton (Jansons and others, 1984). 

Additional comments:

 Martin and others (1915) described this deposit differently from later sources. They described it as an 

acidic dike 1 to 6 feet wide that has been shattered and cemented by quartz-calcite stringers carrying arsenopyrite, galena, sphalerite, pyrite, chalcopyrite, and free gold.

Geologic description:

 The principal deposit at this prospect consists of auriferous, sulfide-bearing quartz-calcite veins that heal 

fractures in a 3-foot-wide Eocene(?) felsic dike (Kenai Star dike; see SR022) (Tuck, 1933). The veins make 

up about 2 percent of the dike, which strikes N30E and dips 45 to 60 E. and intrudes slate and sandstone of 

the Valdez Group of Late Cretaceous age (Tuck, 1933; Tysdal, 1978 [MF-880-A]). Thin quartz-calcitecemented fractures in the slate and sandstone have 2.5- to 5-inch-wide sericitic alteration envelopes (Tysdal, 

1978 [MF-880-A]). There is little alteration near the larger quartz veins. The deposit was explored by a 

69-foot adit. A sample of mineralized dike yielded a small amount of arsenopyrite and a trace of gold. 

Alteration:

 Quartz-calcite-filled hairline fractures in the slate and sandstone are bordered by sericitic alteration envelopes 2.5 to 5 inches wide. 

Age of mineralization:

 Eocene(?) or younger; the veins heal fractures in an Eocene(?) dike.

Location description and accuracy:

 The mine is located in the SE1/4 section 18, T. 9 N., R. 1 W., of the Seward Meridian. It is at elevations 

between 2,800 and 3,100 feet, on the divide between Bear and Palmer Creeks. This is location 7 of Cobb 

and Richter (1972), location 6 of MacKevett and Holloway (1977), location 12 of Cobb and Tysdal (1980), 

and location S-299 of Jansons and others (1984). The location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Ag, Au 

 Other: Pb, Zn 

Ore minerals: Arsenopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The deposit at the Nearhouse mine consists of a banded and brecciated quartz vein averaging 20 inches 

wide. The banding is dark gray and is believed to be attributed to organic material. The vein strikes N50-

80W and dips 60-90N. Metallic minerals include small amounts of arsenopyrite, galena, sphalerite, pyrite, 

and gold, which collectively make up less than one-half percent of the vein material. The vein is cut off at 

both ends by left-lateral transverse faults. However, the vein has good continuity at the surface and to a 

depth of more than 80 feet in the winze (Hoekzema and Sherman, 1983). 

 The host rock is well-bedded, slightly metamorphosed siltstone and sandstone (Hoekzema and Sherman, 

1983) of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The beds strike N15E and 

dip 60W at the 3,100-foot adit level. Abundant sedimentary features at the portal suggest that the bedding 

is overturned (Mitchell, 1979). Felsic dikes crop out nearby, and one was intersected in the east drift of the 

3,100-foot level adit. 

Alteration:

 

Age of mineralization:

 Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age.

 The workings at this mine consist of two adits: the upper adit, at 3,100 feet elevation, has 450 feet of 

workings plus an 80-foot winze; the lower adit, at an elevation of 3,050 feet, is 35 feet long (Jansons and 

others, 1984). In 1981, some old equipment at the site included a Worthington compressor. An old mine 

road leads to the workings from the Palmer Creek road. 

 Tuck (1933) visited the mine in 1931 and collected eight samples that assayed from 0.03 to 1.3 ounces of 

gold per ton and 0.3 to 3.5 ounces of silver per ton. The gold assays of the eight samples averaged 0.7 

ounce per ton. 

 In 1980 and 1981, the U.S. Geological Survey and U.S. Bureau of Mines mapped and sampled the deposit 

(Hoekzema and Sherman, 1983). The Bureau collected six chip samples that assayed from a trace to 0.45 

ounce of gold per ton and from 0.02 to 0.13 ounce of silver per ton. Reserves are estimated at 7,000 tons of 

ore containing 0.2 ounce of gold per ton and 0.3 ounce of silver per ton (Jansons and others, 1984). 

Production notes:

 Recorded production is 102 ounces of gold and 3 ounces of silver (Jansons and others, 1984). 

Reserves:

 Reserves are 7,000 tons of ore containing 0.2 ounce of gold per ton and 0.3 ounce of silver per ton 

(Jansons and others, 1984). 

Additional comments:

 Hoekzema and Sherman (1983) reported dynamite and caps in the west drift of the 3,100 foot level. The 

explosives were destroyed by the Army Explosive Ordinance Disposal Unit in 1995 (C. S. Huber, oral communication, 2000).

Geologic description:

 The Whistler deposit consists of an auriferous, sulfide-bearing, quartz vein in slate of the Valdez Group of 

Late Cretaceous age (Tuck, 1933; Nelson and others, 1985). The vein is 2 to 6 inches thick and nearly parallel to the cleavage of the slate, which strikes N25E and dips 72E. An adit was driven on this vein for a 

distance of 50 feet, but the vein is cut off by a fault that strikes N70E and dips 80N. Tuck (1933) speculated that the fault displacement was small and that the continuation could be found, but the vein proved too 

small to be mineable.

Geologic description:

 The deposit at this prospect consists of auriferous, arsenopyrite-bearing quartz-calcite veins that heal fractures in a 5-foot-wide, Eocene(?) felsic dike locally called the Kenai Star dike. The dike strikes N30E and 

dips 45-60E (Tuck, 1933) and intrudes slate and sandstone of the Valdez Group of Late Cretaceous age 

(Nelson and others, 1985). Sericitic alteration envelopes, 0.4 to 0.8 inch wide, surround tiny fractures cutting the slate and sandstone country rock, but there is little alteration near the larger quartz veins in the dike 

(Mitchell, 1979). 

 Hoekzema and Sherman (1983) refer to this prospect briefly under the name Downing mine (SR017), as a 

fractured dike occurs nearby. 

Alteration:

 Sericitic alteration envelopes 0.4 to 0.8 inch wide surround tiny fractures cutting slate and sandstone

(Tuck, 1933). Mitchell (1979) visited the property in 1977 and reported 69 feet of workings. The U.S. Bureau of Mines visited the nearby Downing mine in 1982, but did not sample the prospect described in this 

record (Hoekzema and Sherman, 1983). Tuck (1933) wrote that nowhere on the Kenai Star dike was there 

observed anything that might be considered ore. 

Production notes:

 The U.S. Bureau of Mines reported production of 150 ounces of gold from the Downing mine, which presumably included any production from the Francisco, Bonanza, and Whistler properties (Jansons and others, 

1984). None of the production is believed to have come from the prospect described in this record.

Additional comments:

 In his description of this deposit, Tuck (1933) included references to the Francisco (SR017), Whistler 

(SR020), and Bonanza (SR018) properties on Bonanza Creek. This unnamed prospect is east of those properties that are collectively known as the Downing mine (Jansons and others, 1984).

Location description and accuracy:

 This mine is located in the E1/2 section 30, T. 9 N., R. 1 W., of the Seward Meridian, at elevations between 2,200 and 2,400 feet. It is situated on the south valley wall of Coeur d'Alene Creek, about a mile 

from its mouth. It is accessible by Palmer Creek road at a point 7 miles from Hope. This is location 8 of 

Cobb and Richter (1972), location 7 of MacKevett and Holloway (1977), location 15 of Cobb and Tysdal 

(1980), and location S-296 of Jansons and others (1984). This location is accurate to within a quarter of a

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Calcite, quartz 

Geologic description:

 This deposit consists of auriferous, sulfide-bearing, quartz-carbonate veins that heal fractures in an Eocene felsic dike. The dike is as much as 6 feet wide, strikes N10E to N30E, and dips vertically. The quartz 

veins mostly strike N15W to N55W and dip steeply east . Metallic minerals in the veins are sparse and include arsenopyrite, pyrite, chalcopyrite, galena, and sphalerite (Jansons and others, 1984). The host rock is 

slate of the Valdez Group of Late Cretaceous age (Nelson and others, 1985), which stikes N30E and dips 

vertically (Tuck, 1933). 

 The dike, locally called the Kenai Star dike, has been isotopically dated at 53.2 +/- 1.6 million years 

(Siberman and others, 1981). It is very similar to other mineralized felsic dikes of the region (for example, 

see SR136). 

It strikes generally north, dips vertically, and ranges in width from 1 to 6 feet (Martin and others, 1915). 

Regionally, the dike cuts across the cleavage of the slate, but locally, owing to later movements, it may be 

parallel to the cleavage. The dike is erratically fractured and cut by quartz veins and stringers that at many 

places form as much as 30 percent of the dike rock. The sulfide minerals form only a small portion of the 

vein material and are very erratically distributed (Tuck, 1933). 

 North from this deposit, the Kenai Star dike has been traced for about a mile to the divide between Bear 

and Cub Creeks. To the south it runs along the divide between Alder and Palmer Creeks for about 4 miles 

(Tuck, 1933). 

Alteration:

 

Age of mineralization:

Workings/exploration:

 Underground workings on this mine consist of two drifts. One at 2,250 feet elevation is 60 feet long, and 

the other at 2,200 feet elevation is a 120 feet long (Jansons and others, 1984). Trenches are also present. 

Improvements include a road. At one time, a 5-stamp mill was installed, and in 1922 several tons of rock 

from the more heavily mineralized portions of the dike was mined. The operation did not prove profitable, 

and the mill was dismantled and moved to the Hirshey property (Hirshey-Lucky Strike mine, SR011) (Tuck, 

1933). 

 The prospect was sampled and mapped by Mitchell (1979) in 1977. Mitchell reported values between 0.3 

and 0.4 ounce of gold per ton. The U.S. Bureau of Mines examined the prospect in 1979. They collected 

two chip samples that assayed a trace and 0.15 ounce of gold per ton and a trace and 0.06 ounce of silver 

per ton. 

Production notes:

 Reported production is 24 ounces of gold (Hoekzema and Sherman, 1983). Jansons and others (1984), 

however, do not report any production, probably because there is no formal record of any.

Geologic description:

 Sixmile Creek flows in a broad, flat-bottomed valley in its upper half, cuts into Valdez Group bedrock of 

Late Cretaceous age for about 3 miles, and then broadens into a wider valley for about its final 3 miles 

(Tysdal, 1978 [MF-880-B]). Several bedrock canyons along its channel are separated by alluvial terraces 

and partially covered with avalanche debris (Jansons and others, 1984). 

 Jansons and others (1984) indicated that small, auriferous alluvial fan deposits are associated with several 

western tributaries to the lower reaches of Sixmile Creek These include Alder Creek, Cub Creek, and Old 

Woman Creek. The flood-plain deposits near the junction of Sixmile Creek with Canyon Creek appear to 

be fairly thick, with depths to bedrock in excess of 70 feet (Jansons and others, 1984).

 Sixmile Creek has produced only modest amounts of gold (Jansons and others, 1984). At the junction of 

SR027 
Alaska Resource Data File 

Page 57 

this creek and Canyon Creek, an attempt was made to reach bedrock by means of a hydraulic elevator, but at 

the time Paige and Knopf (1907) visited in 1906, the work had ceased. Martin and others (1915) reported 

that placer mining on Sixmile Creek was confined to a very few small hydraulic plants, worked by individuals, operating on high bench gravels bordering the stream and yielding only a small production. Tuck 

(1933) reported that prospecting on the benches in the lower reaches had picked up several old pay channels. Tysdal (1978 [MF-880-B]) indicated that the stream gravels in the lowermost part of Sixmile Creek 

contain muds from Turnagain Arm and have yielded little gold. However, in the lower 3 miles of the creek, 

some gold has been recovered from high bench gravels containing several old channels. 

 According to Jansons and others (1984), the gravels just below Canyon Creek were tested by a backhoe 

and 12-inch suction dredge, but the results are unknown. 

 Overall, the gold is fairly fine, and nuggets larger than one-quarter inch are rarely recovered (Jansons and 

others, 1984). 

 In the early 1980's, the U.S. Bureau of Mines collected a 0.1-cubic-yard sample that contained 0.0017 

ounce of gold per cubic yard. One suction dredge sample from the active stream channel of Cub Creek contained 0.0073 ounce gold per cubic yard. Two section dredge samples collected from channel deposits of 

Sixmile Creek yielded 0.002 and 0.0182 ounce of gold per hour, and one bedrock pan sample contained 

0.0214 ounce of gold per cubic yard (Jansons and others, 1984). 

Production notes:

 The total estimated production is 1,500 to 2,000 ounces of gold, of which less than 250 ounces has been 

produced since 1975 (Jansons and others, 1984). 

Reserves:

 The volume of bench and channel deposits is estimated to exceed 5 million cubic yards. There are no estimates of grade or total gold content (Jansons and others, 1984).

 Gulch Creek and lower East Fork Sixmile Creek occupy narrow bedrock canyons along most of their 

length and contain thin, discontinuous gravel deposits. The bedrock in these drainages is slate and sandstone of the Valdez Group of Late Cretaceous age(Nelson and others, 1985). 

 Gravels in a low bench, mined at the mouth of Gulch Creek, are composed of pebbles and boulders of 

slate, sandstone, and granite and have a clay matrix (Tysdal, 1978 [MF-880B]). Mining about 1.5 miles 

upstream worked old channel gravels consisting of horizontally stratified gravel having a locally compact 

clay and sand matrix (Tysdal, 1978 MF-880-B]). 

 Gravels in the active steam bed range from loose and sandy on the surface, to clay cemented, with bouldery gravel near bedrock. Some of the boulders are 5 feet or more feet in diameter. Fine gold is disseminated throughout the gravels, but the pay streak is on bedrock and in fractures and is accompanied by sticky, 

tan clay (Jansons and others, 1984). The gold is flat, smooth, and medium coarse to coarse (Johnson, 

1912). Nuggets as heavy as 5 ounces have been recovered from Gulch Creek (Jansons and others, 1984).

Workings/exploration:

 Prior to 1906, the placer was worked mainly by pick and shovel. Hydraulic mining predominated from 

1906 through 1917. Most of the gold was taken from the mouth of Gulch Creek and from East Fork SixmileCreek just below its confluence with Gulch Creek. East Fork Sixmile Creek has been worked mainly 

between Gulch Creek and Sixmile Creek (Moffit, 1906). 

 In 1911, two hydraulic plants were in operation. The lower, smaller plant operated at the junction of 

Gulch and East Fork all season using an 8-inch pipe with a 2.5-inch nozzle. A 4,000-foot-long, 2-foot-wide 

ditch provided water. The gravel was piped into two lead boxes and then into a string of nine,12-foot-long, 

1-foot-wide sluice boxes set with pole riffles (Johnson, 1912). The upper plant, situated a short distance 

above the mouth of Gulch Creek, was not in operation when Johnson visited in 1912. There, the gold-saving 

apparatus consisted of a string of 11 sluice boxes with a 3-foot- square cross section laid on bedrock 

(Martin and others, 1915). In 1917, two men were hydraulic mining at the mouth of Gulch Creek (Johnson, 

1919 [B 692-C, p. 175-176]). 

 In the early 1980's, the U.S. Bureau of Mines collected suction dredge samples at the head of Gulch 

Creek. They yielded 0.0006 to 0.0034 ounce of gold per hour. Two other samples from upper Gulch Creek 

contained 0.0008 to 0.0296 ounce of gold per cubic yard. Nine placer samples consisting of surface alluvium collected from the canyon of lower East Fork Sixmile Creek, contained 0.0019 to 0.015 ounce of gold 

per cubic yard (Jansons and others, 1984). 

 Since the early 1980's small-scale suction dredging has become a popular mining method and occurs intermittently up to the present time (C. S. Huber, oral communication, 2000). 

Production notes:

 The total estimated production is 1,000 to 2,500 ounces of gold, of which as much as 250 ounces has been 

produced since 1975 (Jansons and others, 1984). 

Reserves:

 The quantity of the gravel both on the benches and in the active stream channel is limited. No estimate of 

reserves is available.

Geologic description:

 This deposit consists of an auriferous, sulfide-bearing quartz-calcite vein in graywacke and slate of the 

Valdez Group of Late Cretaceous age (Johnson, 1916; Nelson and others, 1985). The vein is 2 to 16 inches 

wide; it strikes N28E and dips near vertically, parallel to the bedding of the graywacke and slate. Metallic 

minerals in the vein consist of chalcopyrite, galena, pyrite, sphalerite, and gold. Workings on the prospect 

consisted of a 22-foot shaft that is now below sea level. 

 A test shipment of 4,200 pounds of ore was shipped to the Tacoma smelter in 1912. This shipment contained 2.6 ounces of gold (Johnson, 1916). The U.S. Bureau of Mines visited this site in 1981and collected

Geologic description:

 The Gulch Creek No. 2 occurrence consists of at least two subparallel quartz-carbonate veins that strike 

N55-60E and dip 45-50SE. The veins average 1.5 feet thick and are locally as much as 4 feet wide. They 

can be traced for 100 to 200 feet along strike. The quartz has a well-developed ribbon structure, is highly 

fractured, and contains arsenopyrite and minor pyrite along the contact with the wallrock. Slickensides 

along the hanging wall of one vein are horizontal and indicate a right-lateral movement (Hoekzema and 

Sherman, 1983). The Valdez Group (Late Cretaceous age) host rock (Nelson and others, 1985) is mostly 

highly fractured slate and metasiltstone having foliation that strikes N30-35E and dips 55-60SE (Hoekzema 

and Sherman, 1983). Five samples were collected by the U.S. Bureau of Mines in 1982.; they assayed trace

Geologic description:

 The Gulch Creek No. 3 occurrence consists of two quartz veins as much as 2 feet thick that occur along a 

well-developed shear zone that averages 4 feet wide. The shear zone strikes roughly northeast and dips vertically and is only one of numerous faults in the area. The larger vein, exposed along strike for about 100 

feet, strikes N65W and dips vertically. The vein is offset in at least three places by northeast-trending faults 

that dip 65SE. The apparent motion of these faults is right lateral, and the displacement is about 5 feet 

(Hoekzema and Sherman, 1983). The shear zone and quartz veins are hosted by slate and metasiltstone of 

the Upper Cretaceous Valdez Group (Hoekzema and Sherman, 1983). The quartz is iron-stained and vuggy 

and contains arsenopyrite. 

 Four chip samples collected in 1981 by the U.S. Bureau of Mines contained less than 0.03 ppm gold and

Geologic description:

 This deposit consists primarily of an auriferous, sulfide-bearing quartz vein, as much as 4 feet wide, in a 

fault that cuts Valdez Group rocks of Late Cretaceosu age (Martin and others, 1915; Cobb and Tysdall, 

1980). The fault strikes NE and dips 70SE. The fault walls are commonly striated and marked by a thin 

gouge. The vein is truncated at both ends by other faults. A second quartz vein, about 3 feet thick, is less 

faulted, but it carries only low gold values. 

 The primary vein contains arsenopyrite, pyrite, chalcopyrite, sphalerite, galena, and free gold. Crystals of 

arsenopyrite are also very abundant in the country rock. 

 This deposit may be an extension of the veins on the Slate Creek No. 1 (SR038) and Slate Creek No. 2 

(SR040) prospects. All three veins are fault-controlled and are nearly on strike (Martin and others, 1915).

feet long. Improvements include an arrastre mill, erected in 1906, that was driven by water power and capable of handling two 700-ton charges per day (Moffit, 1906). Nineteen tons of picked ore was processed and 

yielded approxomately 25 ounces of gold (Hoekzema and Sherman, 1983). 

 The U.S. Bureau of Mines visited the prospect in 1982 and collected four samples from the vein where it 

is exposed in and adjacent to Sawmill Creek. The adit was inaccessible at the time. The samples assayed 

from a trace to 0.04 ounce of gold per ton and a trace to 0.04 ounce of silver per ton (Jansons and others, 

1984). 

Production notes:

 In 1906, approximately 25 ounces of gold were recovered from 19 tons of ore (Hoekzema and Sherman, 

1983). Additional production might have occurred.

Geologic description:

 Granite Creek occupies a fairly wide valley over most of its length; bedrock is exposed in only a few locations. Below Bertha Creek (SR039) the valley is from about a quarter to a third of a mile wide and in many 

places is wet and marshy (Moffit, 1906). Gravel terraces are present, and the whole region appears to have 

been occupied by a lake or series of lakes at one time. Granite Creek is one of the largest tributaries of East 

Fork Sixmile Creek. 

 Near the mouth of Bertha Creek, Granite Creek contains about 8 to 10 feet of coarse gravel. These gravels were hydraulically mined in 1903 and 1904. Some of the mining may have been of Bertha Creek, but 

most of the gold probably came from Granite Creek. About 4 to 5 feet of finer alluvium, overlying the 

coarse gravel is also auriferous (Moffit, 1906). The gold is fine, bright yellow, and fairly smooth. 

 Significant gravel deposits occur along much of Granite Creek.

Workings/exploration:

 Gravel on Granite Creek near it confluence with Bertha Creek (SR039) was hydraulically mined in 1903 

and 1904. Some of the mining may have been on Bertha Creek, but most of the gold probably came from 

Granite Creek. The value of the gold averaged about 15 cents per cubic yard (gold at $20.67 per ounce) 

(Moffit, 1906). 

 The early workings included a rock carrier driven by water power for handling the boulders and a small, 

homemade sawmill. The sawmill was an ordinary whipsaw set in a square upright frame and driven by a 

water wheel with suitable gear; it sawed three times as much in a day as two men can saw by hand (Moffit, 

1906). 

 The U.S. Bureau of Mines sampled Granite Creek in 1982 or 1983. Two suction dredge samples yielded 

0.0007 and 0.0011 ounce of gold per hour. The gold was very fine grained, requiring amalgamation to recover. 

Production notes:

 A small amount of production from the mouth Bertha Creek (SR039) (Moffit, 1906) is believed to have 

actually come mostly from Granite Creek (Cobb and Tysdal, 1980). 

Reserves:

 Jansons and others (1984) reported that significant gravel reserves occur but did not estimate an amount.

Geologic description:

 Bedrock in the area is slate and graywacke of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). Bertha Creek occupies a U-shaped valley in its upper portion and a steep, narrow canyon cut 

mostly in glacial debris and bedrock in its middle section. An alluvial fan below the canyon has been the 

source of the most of the gold recovered to date (2000). The gravels are poorly sorted and contain abundant clay and boulders. The gold occurs mostly on bedrock (Jansons and others, 1984). Moffit (1906) reported that at the mouth of Bertha Creek, 2.5 to 3 meters of coarse gravel and boulders are overlain by 

about 1.5 meters of finer material. Bedrock is not exposed. The gold is in the coarse material, which averages about 15 cents per cubic yard (gold at $20.67 per troy ounce). The gold is fine, bright yellow, and 

smooth (Moffit, 1906). 

 Hand-placer and hydraulic mining occurred between 1902 and 1904, and the area is currently (2000) used 

for recreational mining. Total gold production since 1902 is estimated to be 300 to 600 ounces, of which 

less than 35 ounces has been recovered since 1975 (Jansons and others, 1984).

Workings/exploration:

 Hand-placer and hydraulic mining occurred between 1902 and 1904. In 1983, the U.S. Bureau of Mines 

collected samples from lower Bertha Creek (Jansons and others, 1984). A dredge sample yielded 0.0142 

ounce of gold per hour. Two bench samples contained 0.0006 and 0.0129 ounce of gold per cubic yard. 

Traces of gold were recovered from surface gravels on upper Bertha Creek. A concentrate sample contained cinnabar (Jasper, 1967). Recreational suction dredging is currently popular along Bertha Creek 

within one-eighth mile of the Seward Highway (C. S. Huber, oral communication, 2000). 

Production notes:

 Total gold production since 1902 is estimated to be 300 to 600 ounces, of which less that 35 ounces has 

been recovered since 1975 (Jansons and others, 1984).

 Gold occurs throughout the channel gravels, but it is mostly concentrated on bedrock. Some small areas 

of bench gravels exist in the lower part of the creek; these contain disseminated gold that occurs in sandy, 

boulder-rich gravel resting on a 6- to 12-inch-thick clay layer (Jansons and others, 1984). The gold in both 

the bench and channel deposits is fairly fine, although particles as long as three-sixteenths of an inch have 

been recovered. 

 The U.S. Bureau of Mines collected six suction-dredge samples of bench and channel gravels in 1979.

Geologic description:

 Wolverine Creek drains a small glacier on the west side of hill 3783. Gold occurs in the active stream 

channel in small pockets of well-washed gravel and trapped under large boulders (Jansons and others, 

1984). Bedrock in this area is slate and graywacke of the Valdez Group of Late Cretaceous age (Nelson 

and others, 1985). There is evidence of hand mining about one-half mile above the junction with Igram 

Creek. There is no known production. The U.S. Bureau of Mines collected suction dredge samples in 1978 

and estimated a recovery rate of 0.0036 ounce of gold per hour (Jansons and others, 1984).

Location description and accuracy:

 The placer mine is located in T. 11 N., R. 2 E., of the Seward Meridian. Mining has occurred on two 

places on Crow Creek: (1) the lower part of the creek, and (2) the upper part of the creek, which is in the 

Anchorage A-6 quadrangle (C. S. Huber, oral communication, 2000). This is location 133 of Cobb and

Geologic description:

 Crow Creek drains an area underlain by rocks of the Valdez Group of Late Cretaceous age intruded by 

felsic dikes (Nelson and others, 1985). Placer gold occurs in four types of gravels on Crow Creek: high 

bench gravels, recent stream deposits, glacial gravels, and avalanche debris. The bench and recent stream 

deposits are the highest in grade and have historically produced most of the gold. The glacial and avalanche 

debris deposits are of low grade but may locally contain a significant concentration of gold. The highest 

grades appear to be associated with old channels in high benches, which likely consist of gravels deposited 

prior to the most recent glacial advance (Jansons and others, 1984). 

 Numerous large boulders and cemented gravels have caused mining difficulties (Jansons and others, 

1984). The gold is fairly coarse; nuggets weighing from 0.05 to 1.0 ounce having been found by recreational miners (Jansons and others, 1984).

Workings/exploration:

 Historically, mining on Crow Creek has been concentrated in two areas: (1) the lower part of the creek, 

extending from its junction with Glacier Creek to a point about 2 miles upstream, and (2) the upper basin 

(Anchorage quadrangle), which is covered by a group of patented claims known as the Girdwood property 

(U.S. Mineral Survey No. 753). Most of the production came from the lower part of the creek, primarily 

from a feature known as the (so-called) big cut that was created by hydraulic mining. The big cut is 1,800 

feet long, 600 feet wide, and has a maximum depth of 230 feet (Johnson, 1912). 

 Prior to 1903, most of the mining on Crow Creek was done by pick and shovel on the most easily accessed gold-bearing gravels, but hydraulicking subsequently became the dominant mining method. In 1915, 

four hydraulic giants were working the Crow Creek mine (Capps, 1916). Mining was more or less continuous until 1938, when hydraulic mining ceased because the amount of gold recovered no longer supported 

the mining activity. 

 A mineral patent examination (U.S. Mineral Survey No. 748) was done by R. Shirley, U.S. Forest Service, 

in 1965. Shirley's conclusion was that the property was essentially mined out and contained insufficient reserves to support any successful mining operation. 

 The Bureau of Mines collected 11 bench and alluvium samples from upper Crow Creek. The samples 

contained from 0.0013 to 1.7 ounces of gold per cubic yard (Jansons and others, 1984). Five other samples 

were collected from the active channel of lower Crow Creek. These five samples contained from 0.0021 to 

0.144 ounce of gold per cubic yard (Hoekzema and Fechner, 1986). 

Production notes:

 Crow Creek, the only important gold-producing stream on the north side of Turnagain Arm, has produced 

an estimated 45,000 ounces of gold (Jansons and others, 1984). Two operations accounted for virtually all 

of the production: the Crow Creek mine (Erickson mine) and the Girdwood mine (Anchorage quadrangle) 

(U.S. Mineral Survey No. 253). The Girdwood mine was patented. The Crow Creek mine was by far the 

larger operation. 

Reserves:

 A mineral patent examination (U.S. MIneral Survey No. 748) for the Crow Creek mine (or Erickson mine) 

was done by R. Shirley, U.S. Forest Service, in 1965. Shirley's conclusion was that the property was essentially mined out and contained insufficient reserves to support any successful mining operation. 

Additional comments:

 Crow Creek is located in both the Anchorage and Seward quadrangles. Only the deposit (Crow Creek 

mine, Erickson mine) in the Seward quadrangle is described in this record. The old Crow Creek mine, now 

on private land, is currently a tourist attraction where gold panning and small-scale mining occurs (C. S. 

Huber, oral communication, 2000).

Geologic description:

 Peterson Creek occupies a steep narrow avalanche-debris-filled valley with numerous small waterfalls and

is the Valdez Group of Late Cretaceous age (Nelson and others, 1985) and consists of massive greenstone 

and greenstone tuff, along with small amount of interbedded shale. The greenstone is typically a dense, finegrained, green rock enclosing abundant small, angular fragments of slate (Capps, 1916). 

 There has been hand mining and small-scale suction dredging from the mouth of Peterson Creek upstream 

for about 4,000 feet. Concentrate samples from near the mouth of the Creek contained scheelite, chalcopyrite, native copper, and gold . Total production is less than 800 ounces (Cobb and Tysdal, 1980).

 There are also underground workings that were driven by prospectors seeking lode gold (SR052). Two 

cabins associated with these workings are in the valley above the creek (Capps, 1916). 

Production notes:

Geologic description:

 Capps (1916) described the country rock near the prospect as a massive series of greenstones and greenstone tuffs, with small amounts of interbedded shales. The greenstones are generally a fine-grained dense 

green rock enclosing abundant angular slate fragments. Nelson and others (1985) mapped the bedrock in 

this area as undivided sedmentary strata of the Valdez Group of Late Cretaceous age. 

 The deposit consists of a 2-inch-wide quartz-calcite vein that strikes N60W and dips 75SW. The vein 

contains pyrite, galena, and chalcopyrite along with $12.60 in gold (at $20.67 per ounce) per ton. It is exposed on the northeast side of Peterson Creek at an elevation of 1,100 feet, where a 37-foot -ong drift is 

driven on it. There are numerous other adits and drifts on the prospect, but there are few details on the geology and mineralization. Assay results from these adits ranged to as much as $38.00 in gold ($20.67 per 

ounce) per ton (Capps, 1916).

 This occurrence is one of numerous quartz veins in the general area that are hosted in slate and sandstone 

of the Upper Cretaceous Valdez Group (Cobb and Tysdal, 1980). The vein is exposed for about 100 feet 

along strike and ranges in width from 3 to 12 inches. It is approximately parallel to the north to N20E strike 

of the host rock and has a vertical dip (Jansons and others, 1984). According to Johnson (1914[B 592-G, p. 

234]), the vein contains arsenopyrite, pyrite, chalcopyrite, galena, and gold. Samples of float assayed by the 

U.S. Bureau of Mines contained trace amounts of antimony, gold, and silver (Hoekzema and Sherman, 

1983).

 This occurrence is consists of two sites near the terminus of Billings Glacier, about a mile and a half north 

of Passage Canal. They are in the N1/2 sections 28 and 29, T. 9 N., R. 5 E., of the Seward Meridian. One is 

on the east side of Billings Glacier between 400 and 1,150 feet elevation; the other is along the west side of 

the glacier between 600 and 750 feet elevation. Due to the steep terrain and glacial ice, the sites are fairly 

inaccessible. This is location S-169 of Jansons and others (1984). This location is accurate to within half a 

mile. 

Commodities: 

 Main: Mo 

 Other: Cu, W 

Ore minerals: Chalcopyrite, molydbenite, pyrite 

Gangue minerals: Quartz 

Geologic description:

 The country rock in the area of this occurrence is Valdez Group sedimentary strata of Late Cretaceous age 

that has been thermally silicified at and near the contact with a biotite quartz monzonite stock of probable 

mid-Tertiary age (Hoekzema and Sherman, 1983; Nelson and others, 1985). The stock is locally exposed 

over an area measuring roughly 2,000 by 2,500 feet but much of the area is covered by ice. Its age has not 

been determined, but it probably correlates with the nearby Passage Canal pluton, which has been dated at 

36.6 +/- 1 million years (Hoekzema and Sherman, 1983). Some of the metamorphosed strata are stretched, 

boudinaged, and brecciated. 

 Alteration in the stocks associated with the mineralization consists of an increased quartz content, seriticization of potassic feldspar, destruction of biotite, and a lighter color and coarser texture (Hoekzema and 

Sherman, 1983). Sulfide minerals found to date are restriced to the southern side of the stock within 300 

feet of the contact and between 400 and 1,500 feet elevation. 

 Pyrite, molybdenite, and chalcopyrite are the most abundant sulfides. Molybdenite occurs as disseminated 

masses as much as 1 inch across in stockwork veins, as disseminated grains within the stock, and as a fracture coating on joints near the contact. Pyrite and chalcopyrite mostly form veinlets and disseminated grains 

in the quartz monzonite (Hoekzema and Sherman, 1983). 

 The U.S. Bureau of Mines discovered this occurrence in 1981; they collected 28 chip and grab samples 

(Hoekzema and Sherman, 1983). Molybdenite values ranged from less than 2 ppm to 2,000 ppm; the highest values were in visibly altered granite (2,000 ppm) and in otherwise undescribed granite (1,450 ppm). 

Copper values ranged from 0 to 150 ppm; the highest values were in quartz veins in granite. Other anomalous metal values included 8,600 ppm arsenic in a pegmatite dike and 1,416 ppm tungsten in granite 

(Hoekzema and Sherman, 1983). 

Alteration:

 Alteration of the host rock results in a lighter hue, due to increased quartz content, seriticization of potassic feldspar, destruction of biotite, and generally coarser texture (Hoekzema and Sherman, 1983).

the highest values were in visibly altered granite (2,000 ppm) and otherwise undescribed granite (1,450 

ppm). Copper values ranged from 0 to 150 ppm; the highest values were in quartz veins in granite. Other 

anomalous metal values included 8,600 ppm arsenic in a pegmatite dike and 1,416 ppm tungsten in granite.

 Main: Au 

 Other: Ag, Cu, Pb, Zn 

Ore minerals: Chalcopyrite, galena, gold, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Graphite, quartz 

Geologic description:

 The country rocks at the Portage Bay mine (labeled Portage Mine on the map) are slate of the Valdez 

Group of Late Cretaceous age and Oligocene granite dikes (Cobb and Tysdal, 1980). The deposit consists 

of sulfide-bearing, banded quartz veins in a shear zone at the contact between the slate and the granite. In 

addition to gold, the veins contain as much as about 1 percent sulfides, including pyrite, pyrrhotite, chalcopyrite, galena, and sphalerite. Graphite inclusions impart a banding to the veins. Spotty gold values occur both in the quartz and along graphitic bands (Roehm, 1936 [PE 95-5]). The principal vein is exposed 

for 150 feet, averages about 12 inches wide, strikes N60E, and dips 60NW. It is reported to average 1.5 

ounces of gold per ton (Roehm, 1936 [PE 95-5]). 

 The workings consist of 278 feet of crosscut and 345 feet of drift with 220 feet of stopes and 240 feet of 

raises. One raise, 160 feet in length, reaches the surface at about 1,700 feet above sea level. 

Alteration:

 According to Roehm (1936 [PE 95-5]), the dikes intruding the slate are altered to a greenish color, but he 

did not identify the type of alteration. 

Age of mineralization:

 Oligocene or younger; the veins cut Oligocene intrusive rock. 

Deposit model:

Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a) 

Deposit model number (After Cox and Singer, 1986 or Bliss, 1992):

36a 

Production Status: Yes; small

Workings/exploration:

 The workings consist of 278 feet of crosscut and 345 feet of drift with 220 feet of stopes and 240 feet of 

raises. One raise, 160 feet in length, reaches the surface at about 1,700 feet elevation. The equipment used 

in mining consisted of a type 40 Ingersoll-Rand compressor that delivered 150 cubic feet of air per second 

and Gardner-Denver drills with detachable bits (Roehm, 1936 [PE 95-5]). 

 In 1980, the U.S. Bureau of Mines collected 13 chip, channel, and grab samples Their assays ranged from 

a trace to 0.6 ounce of gold per ton and from a trace to 0.16 ounce of silver per ton (Jansons and others, 

1984). According to company records, there are reserves of 10,000 tons of ore with a grade of 0.6 ounce of 

gold per ton (Hoekzema and Sherman, 1983). 

Production notes:

 Total recorded production is 490 ounces of gold and 60 ounces of silver (Jansons and others, 1984). 

Reserves:

 Total resources indicated by company records are 10,000 tons of ore containing 0.6 ounce per ton gold 

(Steiner, 1965).

Geologic description:

 The prospect is hosted in sheared sandstone and slate of the Upper Cretaceous Valdez Group (Cobb and 

Tysdal, 1980). Felsic dikes occur in the area (Hoekzema and Sherman, 1983). The mineralization consists 

of a series of subparallel, locally banded quartz-calcite veins as much as 5 feet wide that generally strike 

northwest and dip southwest (Hoekzema and Sherman, 1983). The veins contain arsenopyrite, galena, pyrite, sphalerite, and gold. Sulfides occur as podiform masses and disseminated grains in the veins and in the 

shear gouge. 

 The workings on the prospect consist of an open cut about 550 feet long and minor stripping (Hoekzema 

and Sherman, 1983). The U.S. Bureau of Mines sampled this prospect in 1981 and collected four chip samples that ranged in width from 38 to 60 inches and one grab sample. The samples contained 0.03 to 4.9 

ppm gold. The best gold values (4.9 ppm gold) occurred in the 38-inch-wide chip sample, which was described as a quartz vein containing no visible sulfides (Hoekzema and Sherman, 1983).

Geologic description:

 The host rock at the Sweepstake mine is graywacke and slate of the Valdez Group of Late Cretaceous age 

(Nelson and others, 1985), which is cut by numerous Eocene felsic dikes from 6 to 48 inches thick (Johnson 

1914 [B 592-G, p. 229]). 

 The mineralization consists of a quartz-carbonate vein carrying arsenopyrite, chalcopyrite, galena, pyrite, 

sphalerite, stibnite, and gold. The vein is well exposed for about 150 feet and varies in width from 1 to 5 

feet. It strikes east and dips 85N at its upper end and strikes N84W and has a vertical dip at the lower exposure. Near the portal, the vein thins to stringers of quartz-carbonate that cement shattered dike rock 

(Johnson, 1914 [B 592-G, p. 229]. 

 The workings consist of a 170-foot adit, and surface trenches. A 1,800-foot tramway connects the mine to 

a two-stamp mill near tidewater (Hoekzema and Sherman, 1983). 

 The U.S. Bureau of Mines collected six chip and grab samples from the mine and dump that contained 

from trace to 0.08 ounce of gold per ton and from 0.01 to 0.09 ounce of silver per ton. The best sample was 

a 14-inch chip sample from about 75 feet away from the mouth of the portal. This sample consisted of a 

quartz-carbonate vein stained by malachite (Hoekzema and Sherman, 1983).

Latitude: 60.8721 Quadrangle: SR D-4 

Longitude: 148.3796 

Location description and accuracy:

 The mine is located 2,000 feet inland from the head of Pigot Bay between 400 and 700 feet elevation. It 

is located in the NW 1/4 section 15, T. 9 N., R. 6 E., of the Seward Meridian. The Lansing mine symbol is 

mislocated on the USGS topographic map. This is location 128 of Condon and Cass (1958), location 61 of 

Cobb and Richter (1972), location 85 of MacKevett and Holloway (1977), location 135 of Cobb and Tysdal 

(1980), and S-164 of Jansons and others (1984). This location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Au 

 Other: Ag, Pb, Zn 

Ore minerals: Arsenopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Calcite, chlorite, graphite, quartz, sericite 

Geologic description:

 The bedrock in the mine area is phyllite and slate of the Valdez Group of Late Cretaceous age. The rocks 

have been deformed by the Port Wells fault, which is a northeast-trending regional shear zone (Nelson and 

others, 1985). Several boulders of felsic igneous rocks occur near the mine, but there is no evidence that 

they are related to the deposit. 

 The deposit consists of several quartz veins that locally contain varying amounts of arsenopyrite, pyrite, 

galena, sphalerite, and gold. Other gaugue minerals locally include calcite, chlorite, and graphite. The principal veins are numbered 1-3. Mining has occurred on the No. 1 vein, which crops out at about 550 feet elevation, and on the No. 2 vein, which is only exposed in the workings. The No. 3 vein, exposed at an elevation of 1,600 foot, is on strike with the No. 1 vein; it may an extension of the No. 1 vein (Roehm, 1938 [PE 

95-12]). In the main drift, the No. 1 vein forms discontinuous lenses and pods. One lens in the main drift 

was 50 feet in length and ranged in width from a few inches to 18 inches. The quartz is banded, folded, and 

curled and contains graphite bands that carry the greatest gold values (Roehm, 1938). Roehm reported that 

this lens assayed $43 in gold per ton in the drift and $100.00 in gold per ton on the surface (gold at $20.67 

per ounce). Roehm (1938) examined thin sections of this vein and identified two distinct generations of 

quartz. The early quartz is milky white and forms large crystals having distinct faces. The later quartz is 

bluish and finer grained and shows indistinct crystal faces; it also contains abundant wallrock inclusions that 

have a curled appearance. Associated with the younger quartz are calcite and chlorite and extremely fine 

grained sulfides including arsenopyrite, galena, and sphalerite, along with a little gold (Roehm, 1938). 

 The No. 2 vein was discovered when the main adit was being driven and consists of 6 to 8 inches of 

quartz. This vein is not exposed on the surface. A 25-foot drift was driven on this vein, which strikes N50E 

and dips 60NW. The U.S. Bureau of Mines sampled this vein in 1979 and reported no detectable gold or 

silver (Hoekzema and Sherman, 1983). 

 The No. 3 vein is exposed at 1,600 feet above sea level and is intermittently exposed for about 700 feet. 

The general strike of the vein is northeast, and it dips 50 to 60NW. The vein is 6 to 10 inches wide; auriferous sulfides occur as pods and kidneys. Average values of $100 of gold per ton were reported (gold at 

$20.67 per ounce). A 140-foot-long crosscut was driven below the vein, but whether it intersected the vein 

is not reported (Roehm, 1938).

 The recorded production from all the workings is 81 ounces of gold and 24 ounces of silver (Jansons and 

others, 1984). 

Alteration:

 Roehm (1938 [PE 95-12]) reported that the country rock is considerably altered but did not describe 

whether the alteration is mechanical due to tectonics or hydrothermal due to veining. 

Age of mineralization:

 Tertiary or younger; the veins are associated with the Port Wells fault, which northeast of the mine cuts 

Tertiary granitic rocks. 

Deposit model:

Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a) 

Deposit model number (After Cox and Singer, 1986 or Bliss, 1992):

36a 

Production Status: Yes; small 

Site Status: Inactive 

Workings/exploration:

 The working on the various veins are as follows: A 90-foot crosscut intersects the No.1 vein, which was 

followed by drifting along strike for 110 feet. This drift was stoped upward for 5 to 10 feet. The No. 2 vein 

was followed by drifting for 30 feet. A crosscut was started to intersect the No. 3 vein, but not driven far 

enough to intersect it. There are also numerous open cuts and shallow shafts on the No. 1 and No. 3 veins 

(Hoekzema and Sherman, 1983). 

 During the 1930's, Superior Mines, Inc. constructed a small mill complex below the workings. It consisted of a crusher, 3 x 4 ball mill, hydraulic classifier, flotation cells, and a Gibson amalgamator. The ore 

was transported to the mill by a jig-back aerial tram. Power was supplied to the mill by a 20-horsepower 

Fairbanks-Morse diesel motor. The mine was powered by a R40 Ingersoll-Rand 3-stage compressor run by 

a 40-horsepower Fairbanks-Morse diesel motor (Roehm, 1938 [PE 95-12]). 

 During 1979, the U.S. Bureau of Mines visited the mine and collected eight grab samples from the workings. These samples assayed from 0 to 3.9 ppm gold, the best values coming from the stope on the No. 1 

vein. 

Production notes:

 Recorded production from this property is 81 ounces of gold and 24 ounces of silver (Jansons and others, 

1984). 

Reserves:

 The U.S. Bureau of Mines estimated a geologic resource of 500 tons of ore with a grade of 0.1 ounce of 

gold per ton and 0.02 ounce of silver per ton (Hoekzema and Sherman, 1983). 

Additional comments:

 The recorded production from this mine shows a gold-to-silver ratio of 3.4:1, whereas assay results are 

closer to 10:1. Most of the mines in this district also show gold-to-silver ratio of about 10:1.

 Main: Au 

 Other: Ag, Cu, Pb 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite 

Gangue minerals: Carbonate, quartz 

Geologic description:

 The deposit at the Tomboy Ledge mine consists of a single 1- to 28-inch-wide quartz-carbonate vein in a 

shear zone that strikes N35E and dips 65W. The host rock is slate and siltstone of the Valdez Group of Late 

Cretaceous age, which here strikes N20E and dips 65NW (Nelson and others, 1985). Although not directly 

associated with the mineralization, numerous felsic dikes occur in the area (Hoekzema and Sherman, 1983). 

The vein contains arsenopyrite, pyrite, chalcopyrite, galena, and gold. 

 Johnson (1916) reported workings consisting of a 40-foot adit with a 20-foot winze, and a 35 -oot adit. 

The U.S. Bureau of Mines found a 105-foot adit (crosscut) with 40 feet of drift (Jansons and others, 1984). 

 The U.S. Bureau of Mines collected seven chip samples that contained a trace to 1.05 ounces of gold per 

ton and a trace to 0.02 ounce of silver per ton. They estimated reserves of 300 tons of ore containing 0.3 

ounce of gold per ton and 0.06 ounce of silver per ton. 

 Recorded production is 219 ounces of gold and 9 ounces of silver (Jansons and others, 1984).

Workings/exploration:

 The deposit at this mine was discovered in 1912 by I. Westburg and J. Domenzet. In 1914 they drove a 

40-foot adit with a 25-foot winze and a 35-foot adit (Johnson, 1914 [B 592-G, p. 233]). In 1982, an adit at 

2,000 feet elevation was open (Jansons and others, 1984). 

 The U.S. Bureau of Mines visited the mine in 1981 (Hoekzema and Sherman, 1983). They mapped and 

sampled the adit located at 2,000 feet elevation. They collected a total of seven chip samples, three from 

the adit, and four from elsewhere on the property. The samples contained a trace to 1.05 ounces of gold per 

ton and a trace to 0.02 ounce of silver per ton. 

Production notes:

 Total recorded production is 219 ounces of gold and 9 ounces of silver (Jansons and others, 1984). 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 300 tons of ore having a grade of 0.3 ounce of gold per

Geologic description:

 The Mineral King mine is along the sheared contact between fine-grained dark-gray graywacke and argillite of the Valdez Group of Late Cretaceous age and a large Tertiary granitic dike (Nelson and others, 

1985). The sedimentary strata strike N56E and dip NE. The dike strikes northeast, and the dip is nearly vertical (Hoekzema and Sherman, 1983). The deposit consists of quartz-cemented shattered country rock in a 

shear zone that strikes N26W and dips 45E. The deposit is traceable along strike for about 200 feet. The 

mineralized breccia, which fills the shear zone, is 2 to 6 feet wide and averages about 3 feet wide. The 

quartz contains arsenopyrite, sphalerite, chalcopyrite, galena, pyrite and gold (Johnson, 1914 [B 592-G, p. 

231-232]). 

 There are 1,488 feet of underground workings, consisting of a tunnel and a 780-foot-long adit with stopes 

and winzes. The workings are 450 feet above sea level; a mill is near sea level. The adit provided haulage 

from the vein to the tramway that fed the mill. 

 A 16-inch-wide quartz vein is about 360 feet from the portal. The vein contains considerable shattered 

country rock along with calcite. The vein was stoped from the 450-foot level to the surface at 650 feet elevation. The length of the stope varies from 230 feet to less than 100 feet near the surface (Hoekzema and 

Sherman, 1983).

 The vein was stoped from the 450 level to the surface at 650 feet elevation. The length of the stopes varies from 230 feet to less than 100 feet near the surface (Hoekzema and Sherman, 1983). 

 The mill consisted of a jaw crusher, two 1,350-pound stamps, a Wilfley concentrating table, and an 9 by 

8 Ingersoll Rand air compressor. The compressor was driven by water taken from Eaton Creek (not named 

on the topographic map) under a head of 200 feet. A 7 by 6 compressor powered by a gas engine was situated at the portal for use when water was not available for the pelton-driven compressor (Pilgrim, 1933). 

 The U.S. Bureau of Mines collected nine grab and chip samples, which contained from a trace to 0.15 

ounce of gold per ton and from 0.01 to 0.13 ounce of silver per ton (Hoekzema and Sherman, 1983). 

Hoekzema and Sherman (1983) speculated that the high-grade portions of the vein may have been mined 

out. 

Production notes:

 The U.S. Bureau of Mines estimates that total production was 2,783 ounces of gold and 629 ounces of 

silver from 3,500 tons of ore (Hoekzema and Sherman, 1983). 

Reserves:

 The U.S. Bureau of Mines estimates a resource of 500 tons of material with a grade of 0.012 ounce of 

gold per ton and as much as 5,000 tons of untested tailings (Hoekzema and Sherman, 1983).

Geologic description:

 This prospect is hosted by slate and graywacke of the Valdez Group of Late Cretaceous age (Jansons and 

others, 1984). The deposit consists of numerous irregular quartz stringers in a folded and faulted shear 

zone. The shear zone strikes between S10W to S40W and dips 60NW (Johnson, 1914 [B 592-G, p. 232]). 

 The quartz stringers are generally parallel to each other and to the strike of the shear zone. The longest 

stringer is traceable for about 60 feet; its width varies between 3 and 12 inches. A winze is sunk on this 

stringer. 

 The ore consists of quartz, cream-colored carbonate (ankerite or calcite), chalcopyrite, galena, and pyrite, 

but the ore minerals are not abundant (Johnson 1914 [B 592-G, p. 232]). 

 Workings on the prospect consist of a 40-foot-long adit and a winze of unknown depth. No assay results

 This prospect is located near sea level on the south shore of Bettles Bay, a northwest-trending bay in Port 

Wells. It is located in the NW1/4 section 24, T. 10 N., R. 6 E., of the Seward Meridian. This is location 

location 125 of Condon and Cass (1958), location 64 of Cobb and Richter (1972), location 83 of MacKevett 

and Holloway (1977), location 130 of Cobb and Tysdal (1980), and location S-157 of Jansons and others 

(1984). The location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Au 

 Other: Pb, Zn 

Ore minerals: Arsenopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Carbonate, quartz 

Geologic description:

 The prospect is hosted in slate and sandstone of the Valdez Group of Late Cretaceous age that is intruded 

by Oligocene felsic dikes (Tysdal, 1978 [MF-880-A]). The sedimentary rocks strike N48E and dip 66N. 

The felsic dike is 18 inches wide, strikes N43E, and dips vertically. The deposit consists of two intersecting 

quartz-carbonate veins that, at the portal, respectively strike N15W and N20W and dip 72W and 86W. The 

veins merge underground and continue along a 4-foot-wide, N20W shear zone. The veins are banded with 

quartz and carbonate that carries arsenopyrite, galena, sphalerite, and gold (Johnson 1914 [B 592-G, p. 

232]). The U.S. Bureau of Mines assayed five samples from the workings; they contained a trace to 0.77 

ounce of gold per ton and a trace to 0.41 ounce of silver per ton (Jansons and others, 1984). 

Alteration:

 

Age of mineralization:

 Oligocene or younger; quartz veins cut an Oligocene dike.

Production Status: None 

Site Status: Inactive 

Workings/exploration:

 Workings consists of a single 45-foot adit with a 40-foot-deep winze and some stripping (Johnson, 1914 

[B 592-G, p. 232]). A rotten log structure is located immediately above the portal (Hoekzema and

Sherman, 1983). 

 Jansons and others (1984) assayed five samples; these contained a trace to 0.77 ounce of gold per ton and 

a trace to 0.41 ounce of silver per ton. They described the workings as very hazardous and did not attempt 

to map them. 

Production notes:

 

Reserves:

 The U.S. Bureau of Mines estimates a resource of 500 tons of ore grading 0.3 ounce of gold per ton and 

0.24 ounce of silver per ton (Hoekzema and Sherman, 1983). 

Additional comments:

 U.S. Bureau of Mines reports a 47-foot adit with a 20- to 30-foot winze (Jansons and others, 1984). This 

differs from Johnson's (1914 [B 592-G, p. 232]) description of the workings.

Geologic description:

 The host rock at this prospect is slate and graywacke of the Valdez Group of Late Cretaceous age intruded by an Oligocene felsic dike (Tysdal, 1978 [MF-880-A]). The dike, which ranges from 1 to 8 feet 

wide and averages 3 feet wide, is cemented with numerous quartz stringers that contain arsenopyrite, 

sphalerite, galena, and gold. The dike is traceable across the ridge from Bettles Bay to Hummer Bay, where 

it crops out about 2,000 feet above the head of the bay. 

 A 400-foot-long adit was driven between 1914 and 1919 along the mineralized dike, but, except for a test 

shipment, there is no reported production (Johnson, 1919 [B 692-C, p. 143-151]). Jansons and others

Location description and accuracy:

 The mine is located in the SE1/4 section 9, T. 10 N., R. 7 E., of the Seward Meridian. The mine and mill 

complex extend from sea level to 700 feet elevation, just inland from the shore of Port Wells between 

Harrison Lagoon and Hobo Bay. This is location 117 of Condon and Cass (1958), location 71 of Cobb and

Commodities: 

 Main: Ag, Au 

 Other: Cu, Pb, Zn 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite, sphalerite, stibnite 

Gangue minerals: Calcite, chlorite, graphite, quartz 

Geologic description:

 The Granite mine is hosted in slate and graywacke of the Valdez Group of Late Cretaceous age that has 

been cut by a large mass of Tertiary biotite granite. The granite is altered near the main vein to a light-gray 

to greenish-gray rock ( Hoekzema and Sherman, 1983). 

 Most of the production has come from the main vein, which has a general strike of N50W to N70W and a 

dip of 43 to 55 N, although there is considerable variation in strike and dip in the workings (Johnson, 1915). 

The main vein is cut in numerous places by small normal faults. The main vein ranges from 3.5 inches to 

more than 14 feet in width and averages about 3.5 feet wide. The character of the vein varies with the country rock. In the sedimentary rocks, it consists of shattered slate, graywacke, and argillite cemented by veins 

and networks of sulfide-bearing, porous white crystalline quartz, accompanied by minor graphite, calcite, 

and chlorite. In the granite, the vein is a single structure, although at its widest part it consists of numerous 

shattered masses of altered granite cemented by quartz veinlets (Johnson, 1915). 

 The ore minerals consist of arsenopyrite, chalcopyrite, galena, pyrite, sphalerite, stibnite, and gold. Gold 

occurs as flakes and nuggets associated with graphite bands in the quartz veins (Roehm, 1936 [PE 95-6]). 

Generally the veins appear to have been higher in grade and more extensively stoped where hosted by metasedimentary rocks than by granite (Hoekzema and Sherman, 1983). 

 Total production from this mine was 31,919 tons of ore that contained 24,440 ounces of gold and 2,492 

ounces of silver (Jansons and others, 1984). 

Alteration:

 Granite is altered to a light-gray to greenish-gray rock (Johnson, 1915). 

Age of mineralization:

 Tertiary or younger; the veins cut Tertiary granite.

Site Status: Inactive 

Workings/exploration:

 The Granite mine consists of about 8,200 feet of workings that produced 31,919 tons of ore that contained 

24,440 ounces of gold and 2,492 ounces of silver (Jansons and others, 1984). Most of the production occurred between 1914 and 1922. The ore was crushed in a 17-stamp mill to minus 40 mesh and passed over 

an amalgamator plate and concentrated on Wilfley and Deister tables. Power to the mine was provided 

originally by an oil-fired steam boiler that furnished steam for a 180-horsepower electric generator (Smith, 

1917 [BMB 142, BMB 153]). 

 In 1982, the 350-foot-level adit was accessible, but the 200-foot-level adit was caved at the portal. The U.

S. Bureau of Mines collected 25 samples from the mine and two samples of tailings (Hoekzema and 

Sherman, 1983). The mine samples contained from nil to 6.1 ppm gold. The tailing samples contained 

0.18 and 0.19 ounce of gold per ton. The tailing samples were tested both by fire assay and cyanide bottle 

rolls. Bottle rolls and simulated heap leach tests indicated that 80 percent of the gold could be recovered by 

cyanidation. 

Production notes:

 The U.S. Bureau of Mines visited the Granite mine on several occasions during the RARE II study in the 

early 1980's (Hoekzema and Sherman, 1983). On the basis of past mining history and on low but persistent 

gold values present in samples collected by the Bureau, additional work appears to be warranted. The existing workings, however, appear to have nearly exhausted the deposit. Additional work thus should include 

drilling to identify possible vein extensions. Generally, the veins appear to have been higher in grade and 

more extensively stoped where hosted by metasedimentary rocks rather than by granite. However, high values were identified in samples of a granite-hosted portion of the vein located at the face of the 350-foot 

level (sample 5740A). 

 A 200-pound sample of the tailings was collected in 1982. This sample was sent to the Bureau of Mines 

laboratory in Juneau and to Helner Lindstrom Associates Inc. in Nevada. Both labs analysed the tails and 

obtained assays of about 0.18 to 0.19 ounce of gold per ton. The Bureau lab attempted to recover gold by 

amalgamation, but only 29 percent was recovered. Heiner Lindstom Associates Inc. performed bottle roll 

and simulated heap leach tests of the tailings. Both tests indicated that about 85 percent gold recovery 

could be obtained by cyanidation. The simulated heap leach test recovered 80 percent of the gold after 7 

days. Apparently, amalgamation alone would not be sufficient to recover gold from the tailings, possibly 

because much of the gold is stained due to oxidation of sulfides. 

 The Bureau concluded that there is moderate mineral development potential for small to medium-size lode 

operation and high potertial for a cyanide leaching operation (Hoekzema and Sherman, 1983). 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 1,860 tons of ore containing a grade of 0.78 ounce of 

gold per ton and 30,000 tons of tailings containing 0.18 to 0 0.19 ounce of gold per ton (Hoekzema and 

Sherman, 1983).

with the Esther granite of Tertiary age (Cobb and Tysdal, 1980). The deposit consists of stringers and 

masses of sugary quartz along a 5- to 6-foot-wide shear zone that strikes N40E and dips 85NW. 

 Workings on the prospect consist of an 8-foot-long adit. A poorly defined zone of bluish quartz along the 

west wall of the adit contained considerable free gold, along with chlorite, chalcopyrite, pyrite, galena, and 

pyrrhotite (Roehm, 1938 [PE 95-14]). Three channel samples collected in 1937 contained 0.11, 0.08, and 

0.75 ounce of gold per ton, along with traces of silver (Roehm, 1938 [PE 95-14]).

Location description and accuracy:

 The prospect is located at an elevation of 800 feet, above the west shore of Esther Lake in the southwest 

portion of Esther Island. (It is reported to be one mile from shore.) The prospect is in the W1/2 section 31, 

T. 9 N., R. 8 E., of the Seward Meridian. This is location 89 of Condon and Cass (1958), location 85 of 

Cobb and Richter (1972), location 105 of MacKevett and Holloway (1977), location 168 of Cobb and Tysdal (1980), and location S-125 of Jansons and others (1984). This location is accurate to within half a mile.

Geologic description:

 The prospect consists of a 40-foot adit in contact-metamorphosed slate and sandstone of the Valdez 

Group of Late Cretaceous age near the margin of the Esther pluton of Tertiary age (Cobb and Tysdal, 

1980). The adit was driven on a 4- to 5-foot-wide shear that strikes N14E and dips 85W. The margin of the 

shear zone is well defined with abundant clay gouge. Quartz veins in the shear zone range in size from less 

than 4 inches to more than 2 feet in width and consists of bluish-white quartz containing chalcopyrite, pyrrhotite, and gold (Johnson, 1914 [B 592-G, p. 234-235]). 

 Fieldwork by the U.S. Bureau of Mines in 1979 failed to locate the adit. Their sample of a vertical, 

N25E, 40-inch-wide, pyrite-bearing quartz vein in the vicinity did not contain any significant metals values 

(Hoekzema and Sherman, 1983). 

Alteration:

 A 40-foot adit was driven in 1912 (Johnson, 1914 [B 592-G, p. 234-235]). The U.S. Bureau of Mines 

searched for the prospect in 1979, but did not locate any workings. In the vicinity, they found and sampled 

a 40-inch-wide pyrite-bearing quartz vein striking N25E and dipping vertically. The vein assayed at 0.04 

ppm gold, 0.2 ppm silver, 75 ppm copper, 5 ppm lead, 50 ppm zinc, and 30 ppm arsenic (Hoekzema and 

Sherman, 1983).

Geologic description:

 The prospect consists of a single, shattered-appearing quartz vein that ranges from 3 to 6 feet-wide, hosted 

in sedimentary rocks of the Valdez Group of Late Cretaceous age (Jansons and others, 1984). The vein is 

exposed for 40 feet along strike and contains quartz, arsenopyrite, and pyrite. Free gold was panned from 

the vein (Johnson, 1914 [B 592-G, p. 223-224]); Johnson reported no assay results. However, the U.S. Bureau of Mines collected a stream-sediment sample in the area that contained 0.06 ppm gold and 10 ppm silver (Hoekzema and Sherman, 1983).

Additional comments:

 The U.S. Bureau of Mines searched unsuccessfully for the prospect in 1979 (Hoekzema and Sherman, 

1983). The prospect was located in 1991 by Forest Service and U.S. Bureau of Mines personnel. There 

was abandoned dynamite in a short adit. The adit and dynamite were destroyed in 1994 by the U.S. Army 

explosives disposal personnel (C. S. Huber, oral communication, 2000).

Geologic description:

 The country rocks at this prospect are sheared graywacke and slate of the Valdez Group of Late Cretaceous age. The deposit consists of lenses and stringers of quartz carrying arsenopyrite, galena, and gold 

(Cobb and Tysdal, 1980). The workings on the prospect consist of a 10-foot adit and surface stripping. 

 The mineralization is in a shear zone that can be traced for more than 1,000 feet. The zone strikes N60E 

and dips 70N and varies in width from 2 to 4 feet. It contains shattered and sheared graywacke and slate 

and quartz veins that parallel the walls (Johnson, 1914 [B 592-G, p. 222]). 

 The quartz veins in the adit range in width from 1 to 6 inches and are bluish in color. An early assay of 

the quartz veins showed as much as $96.00 of gold per ton (gold at $20.67 per ounce); the sheared host rock 

contained $4 to $5 of gold per ton (Johnson, 1914 [B 592-G, p. 222]). Estimated production is less than 

769 fine ounces of gold (Tysdal, 1978 [MF-880-A]), but there is no formal record of any production 

(Jansons and others, 1984).

sheared host rock contained $4 to $5 of gold per ton (Johnson, 1914 [B 592-G, p. 222]). 

 The U.S. Bureau of Mines searched for the prospect in 1979 but did not find it. They collected a sediment sample from what appeared to be tailings. The sample contained 162 ppm arsenic (Hoekzema and 

Sherman, 1983). 

Production notes:

 One ton of ore was shipped in 1912 through 1913 (Johnson, 1914 [B 592-G, p. 215]). Other than this

Geologic description:

 The deposit at the Golden Eagle mine consists of stringers and lenses of sulfide-bearing quartz as much as 

10 feet wide in a shear zone that is traceable for 400 to 500 feet (Johnson, 1914 [B 592-G, p. 224]). The 

principal sulfide is pyrrhotite, and the quartz is accompanied by calcite and chlorite. The host rock is slate 

and sandstone of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). The shear strikes 

S20W and dips vertically. 

 Workings consist of a 155-foot drift at 500 feet elevation, two 50- to 60-foot stopes, and a 60-foot crosscut. There is also a 45-foot drift at 600 feet elevation (Hoekzema and Sherman, 1983). Improvements include a five-stamp Vulcan Iron Works mill (Hoekzema and Sherman, 1983). 

 Assay results range from nil to $175 in gold per ton; a chip sample from the mouth of the tunnel assayed 

$9.20 of gold per ton (gold at $20.67 per ounce) (Johnson, 1914 [B 592-G, p. 224]). The U.S. Bureau of

of gold per ton (Johnson, 1914 [B 592-G, p. 224]). The U.S. Bureau of Mines sampled this prospect in 

1979, and five chip samples from the workings contained 0 to 2.1 ppm gold (Hoekzema and Sherman, 

1983). 

Production notes:

 Recorded production is 28 ounces of gold and 1 ounce of silver. The U.S. Bureau of Mines estimated a 

resource of 21,000 tons of ore at a grade of 0.1 ounce of gold per ton (Hoekzema and Sherman, 1983).

Geologic description:

 The prospect is hosted in sheared sandstone and slate of the Upper Cretaceous Valdez Group. The deposit 

consists of one or more sulfide-bearing quartz veins in a shear zone that strikes N40E and dips 80 NW 

(Cobb and Tysdal, 1980). The workings on the prospect consist of a 160-foot adit at an elevation of 1,740 

feet above sea level, a shallow shaft at an elevation of 1,800 feet, and surface trenches. The main vein, 

where exposed in the 1,740-level adit, ranges from 4 to 20 inches wide; it strikes N80E and dips 75N. 

Here, the shear zone is 4 to 30 inches wide. The vein contains some calcite and chlorite and is locally 

banded. Metallic minerals include chalcopyrite, galena, pyrite, and pyrrhotite (Johnson, 1914 [B 592-G, p. 

220-221]). 

 The U.S. Bureau of Mines examined this property in 1979 and 1980 and collected 15 samples. The best 

assays were from the face of the 1,740-level adit and from a surface exposure at 1,800 feet elevation. The

Geologic description:

 The host rock at this prospect is sedimentary strata of the Valdez Group of Late Cretaceous age. Bedding 

or foliation in this area generally strikes N35E and dips 85NW. Several quartz veins are exposed at this 

prospect. The principal vein is in a well-developed shear zone in slate and sandstone. This vein is 1 to 3 

inches thick, strikes N75E, and dips steeply north. The shear zone strikes N65E and dips 70NW 

(Hoekzema and Sherman 1983). In addition to quartz, the vein contains disseminated grains of galena, 

sphalerite, arsenopyrite, pyrite, and gold. 

 The main working located is at 1,390 feet elevation and consists of a 270-foot drift driven on a quartz 

vein. 

 Four samples were collected by the U.S. Bureau of Mines in 1980. Three chip samples contained from a 

trace to 0.06 ounce of gold per ton and from 0.01 to 0.10 ounce of silver per ton. A select grab sample contained 0.24 ounce of gold per ton and 0.27 ounce of silver per ton (Jansons and others, 1984). Jansons and 

others (1984) reported that small amounts of gold were probably removed from this deposit, but there is no

Geologic description:

 The host rock at this prospect is sedimentary strata of the Valdez Group of Late Cretaceous age (Cobb and 

Tysdal, 1980). The deposit consists of quartz veins containing arsenopyrite, pyrite, pyrrhotite, chalcopyrite, 

and gold. Minor gangue minerals include brown-weathering carbonate, feldspar, and chlorite. 

 The workings consist of a 110-foot adit at 1,600 feet elevation, a shaft at 1,630 feet elevation, a 22-foot 

adit at 1,700 feet elevation, and a shaft at 1,800 feet elevation. Improvements included a two-stamp mill. 

 The upper shaft was sunk on a 5-foot-wide shear zone with a 16- to 18-inch-wide quartz vein. The shear 

strikes N65W and dips 45W. About 20 feet northwest of the shaft, the vein pinches out to four inches wide 

and occurs along the hanging wall of the shear (Johnson, 1914 [B 592-G, p. 219-220]). The veining in the 

lower working is described as thin, discontinuous, quartz veins generally parallel to the shear margins. 

Some ore was shipped from the lower shaft in 1912 (Johnson, 1914 [B 592-G, p. 219-220]). No assay results are reported. 

Alteration:

 Sulfides locally altered to limonite. 

Age of mineralization:

 Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age. 

Deposit model:

Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a) 

Deposit model number (After Cox and Singer, 1986 or Bliss, 1992):

Workings/exploration:

 The workings consist of a 110-foot adit at 1,600 feet elevation, a shaft at 1,630 feet elevation, a 22-foot 

adit at 1,700 feet elevation, and a shaft at 1,800 feet elevation. 

 A Hammond two-stamp mill crushed ore, which then passed across three face plates and then on to a concentrate table (Hoekzema and Sherman, 1983). The U.S. Bureau of Mines collected seven chip samples in 

1979 and 1980. The samples contained from nil to 35 ppm gold. The 35-ppm chip sample was taken from a 

surface outcrop near the shaft (Hoekzema and Sherman, 1983). 

 The U.S. Bureau of Mines sampled the exposed vein and short adit in 1979 and 1980. Five grab samples 

contained as much as a trace of gold and silver. A select grab sample contained 1.02 ounces of gold per ton 

and 1.05 ounces of silver per ton. A 24-inch chip sample contained 0.25 ounce of gold per ton and 0.24 

ounce of silver per ton (Jansons and others, 1984). 

Production notes:

 Several tons of ore of the best ore were shipped about March of 1912 (Johnson, 1914 [B 592-G, p. 219]), 

but the returns were not made public. Tysdal (1978 (MF-880A]) estimated a total recovery from this deposit of less than 769 ounces of gold. 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 500 tons of ore with a grade of 0.3 ounce each of gold 

and silver per ton (Hoekzema and Sherman, 1983).

Geologic description:

 The Gray Brothers prospect is near the Contact Fault, which separates sedimentary rocks of the Valdez 

Group of Late Cretaceous age from sedimentary rocks of the Orca Group of early Tertiary age (Cobb and 

Tysdal, 1980). The deposit is a sulfide-bearing quartz vein in a shear zone in green-gray slate and phyllite of 

the Valdez Group. The shear zone is 10 to 20 feet wide; it strikes N30E and dips vertically. The vein is exposed for about 1,000 feet along strike and pinches and swells from 2 inches to 10 feet in width. Pyrite, arsenopyrite, and pyrrhotite have been identified in the vein, but overall, it contains very sparse sulfides. 

Seven samples collected by the U.S. Bureau of Mines in 1979 contained as much as 1,100 ppm arsenic and 

less than 1 ppm gold (Hoekzema and Sherman,1983). Workings consist of a 40-foot adit at 1,550 feet elevation, a 15-foot trench at 1,750 feet, and various prospect pits.

Longitude: 149.6596 

Location description and accuracy:

 This placer mine is located in SE1/4 section 20, T. 5 N., R. 2 W., of the Seward Meridian. Hargood 

Creek (named by the mine owner and not shown on the 1976 revised C-8 quadrangle) is about one-quarter 

mile northwest of and parallel to Crescent Creek. It flows west into Quartz Creek, which flows into Kenai 

Lake near Cooper Landing. This is location P-82 of Jansons and others (1984). This location is accurate to 

within a quarter of a mile.

Geologic description:

 Hargood Creek occupies an abandoned channel in a narrow valley, possibly formerly occupied by a 

stream draining a lateral moraine or esker. Lower Hargood Creek has developed a braided stream channel 

fan that is truncated by Quartz Creek (Jansons and others, 1984). Gold has been concentrated by reworking 

of glacial-fluvial sediments; it is concentrated within certain horizons within each braided stream channel. 

The gold occurs both in active and abandoned channels and as flakes and small nuggets less than threesixteenths of an inch (Jansons and others, 1984). 

 The local bedrock is Valdez Group of Late Cretaceous age (Nelson and others, 1985).

 The U.S. Bureau of Mines collected three samples from the mouth of the creek that yielded 0.0004 to 

0.0315 ounce of gold per cubic yard. The sample size is unknown (Jansons and others, 1984). 

Production notes:

 The U.S. Bureau of Mines estimated the production at less than 350 ounces of gold, of which as much as 

150 ounces have been produced since 1980 (Jansons and others, 1984). 

Reserves:

 The volume of the alluvial fan gravels is estimated to exceed 350,000 cubic yards (Jansons and others, 

1984). No estimates of grade are available.

Location description and accuracy:

 This record is a summary description of several gold placer mines along Canyon Creek and the section of 

Mills Creek below Juneau Creek. All of Canyon Creek and the lower section of Mills Creek (below Juneau 

Creek) are located in T. 7 and 8 N., R. 1 W., of the Seward Meridian. Canyon Creek flows north into Sixmile Creek; Mills Creek joins Canyon Creek 8 miles south of its confluence with Sixmile Creek. The map 

site representing this record is in the NE1/4 section 28, T. 8 N., R. 1 W., of the Seward Meridian. This is 

locations 142, 143, and 145 of Cobb and Richter (1972), location 156, 167, 168, 189, and 206 of 

MacKevett and Holloway (1977), locations 16 and 18 of Cobb and Tysdal (1980), and location P-76 of Jansons and others (1984). This location of the creeks is accurate to 300 feet.

Geologic description:

 Bedrock in this area is Upper Cretaceous Valdez Group slate and graywacke (Nelson and others, 1985). 

Along Canyon Creek the bedrock cleavage generally strikes parallel to the course of the stream. 

 For most of its length Canyon Creek occupies a narrow canyon in a U-shaped valley. The canyon ranges 

in depth from 100 to 200 feet for more than 8 miles, extending from just below Mills Creek to its confluence with Sixmile Creek. Above Mills Creek the valley is open, and the creek has not yet cut deeply into 

the gravels. 

 The gravels in Canyon Creek are rounded and composed primarily of the local bedrock, although a few 

granitic boulders are present near its confluence with Sixmile Creek. Placer gold occurs in alluvial gravels 

in the current channel of Canyon Creek and in bench gravels at elevations as high as at least 100 feet above 

the present stream level. The bench gravels are locally compacted, cemented by iron oxide, and contain considerable clay (Moffit, 1905). Channel gravels are generally low in volume, but by far the greatest production has come from them (Moffit, 1906). Rich pockets of gold have been found behind some rock points 

and large boulders. Some of the gold is distributed throughout the gravel, but it mostly is on or near bedrock. Gold in the channel gravels generally is coarser in size than the gold in the bench gravels. Nuggets and 

flakes greater than three-sixteenths of an inch are common in the channel gravels, whereas the gold in the 

bench gravels is commonly smaller and flaky (Jansons and others, 1984). 

 Mills Creek is nearly 5 miles long, but the important gold-bearing gravels are in a narrow canyon threequarters of a mile above its confluence with Canyon Creek (Moffit, 1906). The bedrock and gravels are 

similar to those in Canyon Creek; high gravel benches are also present. In contrast to Canyon Creek, gravels in Mills Creek contain a minor amount of limestone pebbles (Moffit, 1905). 

 A gold-bearing, gravel-filled channel near the mouth of Juneau Creek was discovered in 1904 (Moffit, 

1906). The gold is partly scattered through the brownish, cemented gravel, but the best pay lies on top of a 

blue clay. The gold generally is fairly coarse and flattened, but that from the cemented gravel is finer, averaging perhaps one-eighth inch in diameter.

Workings/exploration:

 Early discoveries were made in 1895 on Canyon and Mills Creeks (Tuck, 1933). On Canyon Creek, mining has been carried on with great difficulty because of the narrow channel and swift current. The more extensive operations have involved the construction of wing dams to confine the water to one side of the channel while the other side is being worked. Beginning in 1904, a hydraulic plant operated with some success 

on the bench gravels near the mouth. Paige and Knopf (1907) visited in 1906, a season in which 50,000 cubic yards of gravel was moved by hydraulic methods. In 1911, as in previous years, hydraulic operations 

continued, nearly working out a rock-cut channel about 650 feet long, 100 feet wide, and 30 feet deep 

(Moffit, 1906; Martin and others, 1915). Several other, much smaller hydraulic plants have been worked at 

intervals on the bench gravels of Canyon Creek. A significant amount of work has been done on the high 

bench gravels near the mouth of Pass Creek (Martin and others, 1915). Tuck (1933) reported that all of the 

bench gravels contain gold, but the tenor was low and recovery was costly, owing to the thickness of overburden. 

 Moffit (1906) reported that work on Mills Creek at the mouth of Juneau Creek showed an old channel 

filled with gravels. The channel was mined in 1904, 1905, and 1906. An open cut 650 feet long, 150 feet 

wide, and 100 feet deep was made by a small hydraulic plant (Martin and others, 1915). The plant consisted of 1,400 feet of 12-inch hydraulic pipe and a No. 1 giant piping into a flume 2 feet wide and 650 feet 

long. The cut, reported to have nearly paid for itself, had uncovered only a part of the old channel when 

operations stopped (Martin and others, 1915). 

 Several small mechanized and hydraulic operations mined intermittently from 1955 to 1961 and from 

1977 to 1982 (Jansons and others, 1984). 

 The active stream channels on both Canyon and Mills Creek are now being worked by small suction 

dredges (C. S. Huber, oral communication, 2000). One operation on Canyon Creek has applied for patent, 

but a patent moratorium prevents its processing (C. S. Huber, oral communication, 2000). 

 The U.S. Bureau of Mines collected three samples from bench deposits in the old hydraulic pit below the 

junction of Mills and Canyon Creeks. The samples contained from 0.0001 to 0.14 ounce of gold per cubic 

yard. 

Production notes:

 Canyon and Mills Creeks contained the most productive placer deposits in the entire district. The U.S. 

Bureau of Mines has estimated total production at 35,000 to 40,000 ounces of gold since 1895 (Jansons and 

others, 1984). 

Reserves:

 Channel gravels are generally low in volume. Bench gravels are estimated to exceed 2 million cubic yards 

(Jansons and others, 1984).

Geologic description:

 The two lode deposits described in this record are auriferous quartz veins, lenses, or stringers that contain 

varied, small amounts of arsenopyrite, chalcopyrite, galena, pyrite, pyrrhotite, and sphalerite. The host rock 

is sedimentary rock of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). 

 The Buster prospect is on the left bank of Quartz Creek about one-eighth of a mile below Devils Creek. 

The country rock consists of sheared slate and graywacke that generally strike northeast and dip northwest. 

Little or no fault gouge occurs on either the footwall or hanging wall of the vein. The vein consists of vuggy 

quartz and massive or crystalline arsenopyrite. Some small stringers of quartz are in the footwall slate. 

These stringers, when crushed and panned, contained free gold (Martin and others, 1915). No assay results 

are reported for the main vein. 

 The Kaffir Ledge prospect on the east bank of Quartz Creek is about 100 yards above the mouth of Devils 

Creek about 40 feet above the stream level. The vein was discovered in 1911 and explored by numerous 

surface cuts and a 20-foot-long crosscut. The deposit consists of quartz lenses as much as 1 foot thick in 

slate and sandstone of the Valdez Group (Nelson and others, 1985). 

 In addition to the two deposits described in this record, numerous other, similar deposits have been identified on Quartz Creek during placer mining, but none have contained appreciable gold values (Tuck, 1933).

Geologic description:

 Quartz Creek drains an area underlain by slate and graywacke of the Valdez Group of Late Cretaceous 

age (Nelson and others, 1985). 

 Quartz Creek is about 16 miles long and drains into Kenai Lake. Upper Quartz Creek (east of the Seward 

Highway) occupies a steep, narrow, avalanche-debris-filled valley partially cut into bedrock. An alluvial 

fan has developed between the mouth of the canyon and about mile 42 of the Seward Highway. The alluvial 

fan deposits are poorly washed and stratified; fine gold is distributed throughout the deposits but is concentrated on bedrock. Gold as much as one-eighth inch in diameter has been recovered (Jansons and others, 

1984). 

 The remainder of Quartz Creek occupies a broader, more gentle valley, with a bedrock canyon along a 

half-mile stretch above Devils Creek. Bedrock crops out in many places in this canyon where interbedded 

slate and graywacke strike N17W and dip 60W (Johnson, 1912). The character of the unconsolidated material covering the bedrock is shown in a ditch that extends along the east side of the valley. It consists of 

compact clay-matrix gravel that contains a few, waterworn, rounded and striated boulders. Small, gravelcovered benches are at different elevations on the canyon sides and along the stream course. High-grade 

channel and bench deposits have been successfully mined in this part of the canyon. 

 The bench gravels are locally stratified and typically compacted. They have a high clay content and commonly contain boulders as large as 3 feet in diameter (Jansons and others, 1984). Bench gravels, containing 

rounded slate and sandstone boulders and varying in thickness from 12 to 22 feet due to the undulating bedrock surface, were mined in 1911. The bench gravels yielded $0.26 to $0.32 per cubic yard, when gold was 

worth $20.67 per troy ounce (Johnson 1912). The gold is mostly flakes, and nuggets coarser than onequarter inch in diameter are rare. 

 The creek gravels are reported to carry coarse gold and to have paid well (Johnson, 1912).

Workings/exploration:

 In 1911, a hydraulic plant operated on Quartz Creek a short distance above the mouth of Devils Creek 

(Johnson, 1912). In this portion of its course, Quartz Creek winds southward in a narrow, steep-sided canyon cut in the bedrock floor of a broad glaciated valley. The plant obtained water from Quartz Creek a 

short distance below the mouth of Johns Creek by a 1.5-mile-long ditch with a grade of one-fourth of an 

inch to the rod (Johnson, 1912). The intake was situated on the west bank of the creek, and the ditch follows the west side of the valley to a point about one-half mile below the intake, where the water was carried 

across Quartz Creek on a 160-foot flume. The pipeline from the penstock to the giants decreased gradually 

from 14 inches to 10 inches at the giant. Two No. 2 Kendall giants with No. 3 nozzles operated under heads 

of 95 to 120 feet. The gold-saving apparatus consisted of 10 sluice boxes. Most ot the gold was captured in 

the first two boxes. Ten men were at work in early 1911; later this force was much reduced (Johnson, 1912). 

 On upper Quartz Creek, pits and trenches were dug in the early 1900's and in the 1950's and 1960's 

(Jansons and others, 1984). 

 In the early 1980's the U.S. Bureau of Mines collected two samples from upper Quartz Creek that assayed 

0.0024 and 0.0384 ounce of gold per cubic yard (Jansons and others, 1984). They also collected several 

samples of untested bench gravels, which contained a trace to 0.0024 ounces of gold per cubic yard. One 

sample of mine-run gravels contained 0.0384 ounce of gold per cubic yard as averaged through 4 feet of 

gravel resting on bedrock. 

 From 1971 to the present (2000), small-scale sluicing and dredging have occurred in and above the canyon of Quartz Creek (C. S. Huber, oral communication, 2000). 

Production notes:

 The U.S. Bureau of Mines estimated production at 1,000 ounces of gold, of which as much as 400 ounces 

have been produced since 1975 (Jansons and others, 1984). The U.S. Bureau of Mines estimated less than 

25 ounces of gold have been produced from upper Quartz Creek. 

Reserves:

 Jansons and others (1984) estimate that there are more than 750,000 cubic yards of bench and channel 

gravels between Devils Creek and Johns Creek.

Geologic description:

 The deposit at the McMillan mine consists of auriferous, sulfide-bearing quartz veins in sheared graywacke and slate of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]). These quartz 

veins are 3 inches to 2 feet wide ard are exposed in at least four locations in a half-mile-wide belt near the 

top and along the southeast flank of the divide south of Slate Creek. 

 The adit is at 3,300 feet elevation. A caved trench is located a quarter of a mile southwest of the adit at an 

elevation of 3,400 feet. A second trench is located 500 feet west of the adit at an elevation of 3,200 feet. 

 Three veins are exposed in the McMillan adit. The best exposed ore is at the intersection of two veins 

approximately 75 feet from the portal. One vein, which strikes north and dips 75E, contains considerable 

galena, sphalerite, and visible gold throughout a thickness ranging from 1 to 2 feet over a 6-foot strike 

length. This vein assayed 0.739 ounce of gold per ton and 0.55 ounce of silver per ton. The second vein, 

which strikes N20W and dips 55E, averages 3 inches thick and contains arsenopyrite, galena, and considerable free gold. This vein assayed as much as 5.04 ounces of gold per ton and 1.2 ounces of silver per ton. 

Both veins are terminated at their southern ends by a fault that strikes N40E and dips 80SE (Hoekzema and 

Sherman, 1983). Gold production is estimated at 769 ounces (Cobb and Tysdal, 1980). 

 These veins are similar to those in a 1.0- to 1.5-mile-wide belt that parallels the Gilpatrick dike and extends from south of Slate Creek to Frenchy Creek.

Workings/exploration:

 Undergroung workings consist of a 170-foot-long adit at 3,300 feet elevation. It strikes N55W and terminates in a 60-foot-long crosscut that strikes N55E. A caved trench is 0.25 mile southwest of the adit at 

3,400 feet elevation, and a second trench is 500 feet west of the adit at an elevation of 3,200 feet. There are 

also several prospect pits (Jansons and others, 1984). A small prospect mill was installed sometime between 1910 and 1917, and several tons of ore were milled at it (Tuck, 1933). 

 The U.S. Bureau of Mines collected 18 samples between 1979 and 1980 and mapped the workings 

(Jansons, 1981). A grab sample from the N20W vein in the adit assayed 5.04 ounces per ton. The best chip 

sample, also from the N20W vein in the adit, assayed 1.485 ounces of gold per ton. Of the 18 samples, three 

had no detectable gold, and the remaining samples contained 0.05 ppm to 14 ppm gold (Hoekzema and 

Sherman, 1983). 

Production notes:

 A small mill was installed sometime between 1910 and 1917, and several tons of ore were milled by it 

(Tuck, 1933). The total gold production is estimated at 769 ounces (Cobb and Tysdal, 1980). 

Reserves:

 The U.S. Bureau of Mines inferred reserves of 250 tons of ore having an estimated grade of 0.2558 ounce 

of gold per ton (Hoekzema and Sherman, 1983).

Geologic description:

 This occurrence consists of two dikes, the Mascot and Iron Mask (Martin and others, 1915). The deposits 

in both dikes are auriferous, sulfide-bearing, quartz-calcite veins similar to those at the Gilpatrick Dike mine 

(SR136). The Mascot dike crops out at the head of the creek on a ridge between Colorado and Fox Creeks. 

This dike strikes north, dips vertically, and is traceable for several hundred feet. At the discovery monument, the dike is 40 inches wide; 3 feet to the east is a smaller dike that ranges from 3 inches to 1 foot wide 

(Martin and others, 1915). On the spur to the north, the main dike has split into six distinct stringers. 

 The Iron Mask dike crops out on the Colorado Creek slope between the Mascot dike and the Gilpatrick 

dike. It is 4 feet wide at the discovery monument. The mineralization of both dikes is similar to that in the 

Gilpatrick dike. 

 The quartz-calcite veins heal fractures in the felsic dikes and contain gold, arsenopyrite, galena, sphalerite 

and possibly chalcopyrite. The dikes are probably Eocene; the country rock is sedimentary strata of the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880-A]).

Geologic description:

 The deposit at the Gilpatrick Dike mine consists of a mineralized Eocene felsic dike (the so-called Gilpatrick dike) and of quartz veins in graywacke and slate of the Valdez Group of Late Cretaceous age adjacent 

to the dike (Mitchell and others, 1981). The dike contains quartz-filled fractures that carry native metals 

and sulfides, including gold, arsenopyrite, galena, and sphalerite and some chalcopyrite, molybdenite, and 

pyrrhotite. These veins and veinlets range in width from a fraction of an inch to 8 or 10 inches (Tuck, 

1933). 

 The slate and graywacke 2 to 10 feet from the dike contain quartz veins that are parallel to the dike. The 

veins are 2 to 12 inches wide and contain the same ore minerals as those in the dike (Tuck, 1933). 

 The dike and adjacent veins are offset by several dextral faults. The presence of gouge on one wall of the 

dike indicates post-mineralization movement along another fault parallel to the dike. The dike continues for 

several miles (see Fresno Creek, SR145), but development at this site is restricted to a few thousand feet of

 This record summarizes the description of several prospects in the SW1/4 section 13, T. 6 N., R. 2 W., of 

the Seward Meridian, including the Slate Creek and Hatcher properties (called mines on the C-7 topographic map). The deposit at the Slate Creek prospect typifies those at the other properties and is described 

in this record. The map site is at an elevation of 2,300 feet on Slate Creek, three-fourths of a mile west of 

the Seward Highway. The workings are on both sides of the creek and southwest of a collapsed mill building. This is location 28 of Cobb and Richter (1972), location 38 of MacKevett and Holloway (1977), location 55 of Tysdal (1978 [MF-880-A]), and location S-252 of Jansons and others (1984). This location is

Commodities: 

 Main: Ag, Au 

 Other: Pb, Zn 

Ore minerals: Arsenopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The deposit at the Slate Creek prospect consists of several auriferous, sulfide-bearing quartz veins of varied thickness and attitude hosted by metamorphosed sandstone and slate of the Valdez Group of Late Cretaceous age (Jansons and others, 1984). The sulfide minerals are arsenopyrite, galena, pyrite, and sphalerite. 

The veins are spatially associated with the southern extension of the Gilpatrick dike (Hoekzema and 

Sherman, 1983). The schistosity of the country rock strikes N15E and dips 60W. One vein, reported to be 4 

to 12 inches wide, assayed 0.04 ounce of gold per ton and 0.2 ounce of silver per ton (Tuck, 1933). 

 In 1980, the U.S. Bureau of Mines collected two grab samples from trenches at 3,100 and 3,400 feet elevation. One sample was lost, but the other assayed 0.08 ounce of gold per ton and 0.31 ounce of silver per 

ton (Jansons and others, 1984).

 Workings on the south side of Slate Creek southwest of the mill include a 75-foot trench at 3,100 feet elevation and a 25-foot trench oriented N45E at 3,400 feet elevation (Jansons and other, 1984). 

 One vein, reported to be 4 to 12 inches wide, assayed 0.04 ounce of gold per ton and 0.2 ounce of silver 

per ton (Tuck, 1933). A U.S. Bureau of Mines sample from one of the trenches assayed 0.08 ounce of 

gold per ton and 0.31 ounce of silver per ton (Jansons and others, 1984). 

 A mill was installed in 1940 by United Mining and Development Company. The equipment consisted of a 

jaw crusher, 25-ton Denver Ball mill, a Denver jig, assay equipment, and a new portable compressor. 

Twelve men were reported to be working on the property in 1940 (Roehm, 1941?). Production records confirm that the mill was also used to treat ore obtained from the Gilpatrick property (SR136) (Tysdal, 1978 

[MF-800A]).

 Main: Au 

 Other: Cu, Mo, Pb, Zn 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, molybdenite, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The deposit at this mine consists of an auriferous, sulfide-bearing, quartz-carbonate vein in locally sheared 

graywacke and slate of the Upper Cretaceous Valdez Group of Late Cretaceous age (Tuck, 1933; Tysdal, 

1978 [MF-880-A]). Tuck (1933) described the vein as striking N15E with an average dip of 60W. Where 

exposed in the lower workings, its width ranges from a few inches to 3 feet, averaging about 13 inches over 

a length of 175 feet. The ore pinches out at the north end of those workings. 

 The vein occupies a fault along which some movement took place before ore deposition and some of it 

after, as is shown by slickensides and sheared quartz (Tuck, 1933). The fault in general parallels the bedding of the graywacke and slate. Graywacke forms the footwall, and slate forms the hanging wall. 

 The sulfide minerals are mainly arsenopyrite, pyrite, galena, and sphalerite and total about 5 percent of the 

ore (Tuck, 1933). The gangue minerals are quartz and minor carbonate. Chalcopyrite, pyrrhotite, and molybdenite have also been reported. Gold occurs both free and with the sulfides. 

 The main workings consist of 900 feet of crosscut, 550 feet of drift, 215 feet of raise, 25 feet of winze, 

and considerable stoping (Hoekzema and Sherman, 1983). There are two caved portals. One is on the north 

side of the creek at an elevation of 1,800 feet, 200 feet west of the mill. The other is on the south side of the 

creek at an elevation of 1,900 feet, 1,000 feet west of the mill. 

Alteration:

 The vein is weathered to a depth of 50 to 75 feet. The quartz is friable and iron stained in this zone. 

Age of mineralization:

 Cretaceous or younger; vein cuts rocks of the Valdez Group of Late Cretaceous age.

Workings/exploration:

 The main workings consist of two levels totaling 900 feet of crosscut, 550 feet of drift, 215 feet of raise, 

25 feet of winze, and considerable stoping (Hoekzema and Sherman, 1983). One portal is on the north side 

of the creek at an elevation of 1,800 feet, 200 feet west of the mill. The other portal is on the south side of 

the creek at an elevation of 1,900 feet, 1,000 feet west of the mill (Hoekzema and Sherman, 1983). Both 

portals were caved when the U.S. Bureau of Mines visited in 1980 (Hoekzema and Sherman, 1983). 

 The U.S. Bureau of Mines collected five samples. One channel sample on a vein exposed above the caved 

1,900-foot-level portal assayed 1.64 ounces of gold per ton and 0.71 ounce of silver per ton. Two chip samples of wallrock assayed trace to 0.05 ounce of gold per ton and 0.01 to 0.09 ounce of silver per ton. Two 

grab samples from nearby dumps assayed 0.02 and 0.04 ounce of gold per ton and 0.02 and 0.04 ounce of 

silver per ton (Jansons and others, 1984). 

Production notes:

 Total recorded production is 1,274 ounces of gold and 256 ounces of silver (Jansons and others, 1984).

 Tuck (1933) reported a 20-foot adit at an elevation of 2,200 feet and open cuts at 2,240 and 2,350 feet. 

Exposures in the adit and open cuts indicate that the quartz-calcite veins and stringers make up about 20 

percent of the dike. The workings were accessed from the Seward Highway by a 2-mile trail on the south 

side of Colorado Creek.

 At the 20-foot adit, two 5-foot-long channel samples yielded respectively, 0.05 ounce of gold and 0.2 

ounce of silver per ton, and 0.01 ounce of gold, 0.2 ounce of silver per ton (Tuck, 1933). The U.S. Bureau 

of Mines visited the prospect in 1979 and found three adits, two of which were caved, and numerous pits 

and trenches (Jansons and others, 1984). They collected three grab samples and a chip sample. One grab 

sample assayed a trace of gold and 0.15 ounces of silver per ton. Two other grab samples and the chip sample assayed a trace of gold and 0.01 ounces of silver per ton (Jansons, 1981).

Location description and accuracy:

 The prospect is at an elevation of 3,800 to 4,250 feet in the NE1/4 section 25, T. 7 N., R. 2 W., of the Seward Meridian. It is on the divide between two south tributaries of Fresno Creek and is designated the Shell 

Mine on the 1994 U.S. Geological Survey Seward C-7 topographic map. This location is accurate to within 

a quarter of a mile. This is location 30 of MacKevett and Holloway (1977), location 43 of Cobb and Tysdal 

(1980), and location S-266 of Jansons and others (1984). 

Commodities: 

 Main: Ag, Au 

 Other: As, Pb 

Ore minerals: Arsenopyrite, galena, gold, pyrite 

Gangue minerals: Quartz 

Geologic description:

 The Shell prospect consists of several quartz veins and at least two mineralized(?) felsic dikes. One of the 

dikes is a continuation of the Gilpatrick dike of Eocene age. The main vein strikes N10 to 15E, dips 

steeply, and carries arsenopyrite, galena, pyrite, and gold. The quartz veins and felsic dikes cut slate and 

graywacke of the Valdez Group of Late Cretaceous age (Tysdal, 1978). 

 Workings consist of an adit at an elevation of 4,100 feet that is caved 70 feet from the portal, a shaft at 

4,150 feet, and numerous dozer trenches and prospect pits (Hoekzema and Sherman, 1983). 

Alteration:

 

Age of mineralization:

 Eocene or younger; the dike is probably Eocene.

Site Status: Inactive 

Workings/exploration:

 Prospect pits in the area were reported as early as 1931 (Tuck, 1933). In the 1950's, there was caterpillar 

prospecting and possible construction of a cabin. The U.S. Bureau of mines examined and sampled the 

prospect in 1979 and 1981. They found an adit at an elevation of 4,100 feet that is caved 70 feet from the 

portal, a shaft at 4,150 feet, and numerous dozer trenches and prospect pits (Hoekzema and Sherman, 

SR146 
Alaska Resource Data File 

Page 298 

1983). Improvements included two standing buildings and a cat trail. 

 The adit was driven to intersect the shaft and is caved at that intersection (Jansons and others, 1984). The 

Bureau could not sample the main vein underground due to caving or on the surface because of snow cover. 

Pits along the trend of the vein indicate a strike length of at least 100 feet. Other quartz veins were examined briefly, but none contained significant ore minerals. Visible gold occurs in quartz piled on the surface 

near the shaft. The deposit appears to be of low grade. 

Production notes:

 

Reserves:

 Reserves were estimated by the U.S. Bureau of Mines at 440 tons at 0.4 ounce of gold per ton and 0.3 

ounce of silver per ton (Hoekzema and Sherman, 1983).

Geologic description:

 Colorado Creek drains an area underlain chiefly by slate and graywacke of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The creek occupies a steep, narrow, avalanche-debris-filled valley 

floored with poorly stratified gravels containing considerable clay. Gold is disseminated throughout the 

gravels; there are minor concentrations on bedrock. The gold generally is fine, although nuggets as large as 

three-eighths of an inch in diameter are reported (Jansons and others, 1984). A small mechanized operation 

mined sporadically on Colorado Creek from 1977 to 1982 with little success. Total production is less than

1985). The strata generally strike N45E and dip 80NW, but considerable faulting causes local variation in 

this attitude. The veins pinch and swell along strike; they are locally hematite stained and contain minor pyrite. One piece of quartz float contained minor disseminated galena.

Site Status: Inactive 

Workings/exploration:

 Claims were located in 1976. One 90-foot shaft was sunk in an unnamed glacier in 1982 (Jansons and 

others, 1984). The U.S. Bureau of Mines visited the site in 1982 and collected two grab samples that contained a trace of gold (Hoekzema and Sherman, 1983). They sampled in a gully, south of the prospect on the 

south side of the divide. 

 In 1988, several structures, explosives, equipment, hazardous materials, and fuel drums were abandoned. 

The U.S. Army Explosive Ordinance Disposal unit destroyed the explosives. From 1995 to 1997 the U.S. 

Forest Service contracted removal of abandoned hazardous materials and burned the structure debris (C. S.

Location description and accuracy:

 The placer mine is located near the east bounary of section 6 in T. 7 N., R. 1 E., of the Seward Meridian. 

The mine is about a mile upstream from the junction of Silvertip Creek with East Fork Sixmile Creek. This 

is location 146 of Cobb and Richter (1972), location169 of MacKevett and Holloway (1977), location 19 of 

Tysdal (1978 [MF-880-B]), location 146 of Cobb and Tysdal (1980), and location P-75 of Jansons and others (1984). This location is accurate to within 300 feet.

Geologic description:

 The upper portion of Silvertip Creek occupies a steep, narrow, bedrock canyon partially filled with avalanche debris. The lower sections occupy a slightly wider channel, where bedrock near the surface is covered by poorly washed and stratified clay-rich gravels containing gold. The lowermost section flows over 

an alluvial fan consisting of moderately well stratified and washed gravels. Bedrock of the area is the Valdez Group of Late Cretaceous age (Nelson and others, 1985). 

 Silvertip gold has been reported to be similar to Gulch Creek gold (see SR029), but the nuggets were not 

so large. Most of the larger nuggets had quartz attached (Johnson, 1912). Scheelite has been found in the 

concentrate (Jasper, 1967).

Production Status: Yes; small 

Site Status: Active 

Workings/exploration:

 Pick and shovel operations occurred between 1897 and 1904. In 1911, a small hydraulic operation was 

attempted about a mile above the point where Silvertip Creek joins East Fork Sixmile Creek (Moffit, 

SR154 
Alaska Resource Data File 

Page 314 

1906). This operation worked the shallow creek gravels, 3 to 4 feet deep, for about six weeks before the 

work was abandoned (Johnson, 1912). The gold was reported to be similar to that at Gulch Creek (see 

SR029), but the nuggets were not so large. Most of the larger nuggets had quartz attached (Johnson, 1912). 

 Small mechanized operations have mined sporadically since 1950 and suction dredges since 1975 

(Jansons and others, 1984). 

 The U.S. Bureau of Mines collected one sample, which yielded .0019 ounce of gold per cubic yard 

(Jansons and others, 1984). 

Production notes:

 The U.S. Bureau of Mines estimated the production at 750 to 1,000 ounces, of which 50 to 100 ounces are 

estimated to have been recovered since 1975 (Jansons and others, 1984). 

Reserves:

 The inferred placer gold reserve base is estimated at greater than 1,000,000 cubic yards (Jansons and others, 1984).

Ore minerals: Arsenopyrite, gold, chalcopyrite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The country rock at this prospect is slate and sandstone of the Valdez Group of Late Cretaceous age 

(Nelson and others, 1985). The deposit consists of auriferous, sulfide-bearing, quartz veins, 6 inches to 2 

feet thick. The veins are in a 3- to 10-foot-wide shear zone that strikes north to N10W, nearly parallel to the 

slaty cleavage of the country rocks (Paige and Knopf, 1907; Tysdal, 1978 [MF-880-A]). The veins contain 

podiform masses of chalcopyrite accompanied by pyrrhotite and pyrite. Pyrite also occurs in the altered 

wall rock (Paige and Knopf, 1907). The deposit has an exposed strike length of about 110 feet. 

Alteration:

 Altered wall rock contains pyrite. 

Age of mineralization:

 Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.

Production Status: None 

Site Status: Inactive 

Workings/exploration:

 Workings include two adits and a prospect pit. The prospect pit is situated above the upper adit. The upper adit, at an elevation of about 2,900 feet, consists of 335 feet of crosscut, 110 feet of drifts, a winze, and 

some minor stope development. The lower adit, at an elevation of about 1,800 feet, is 800 feet long but 

caved (Paige and Knopf, 1907).

 Access is provided by a 4-wheel-drive road that begins at the Bench Lake trailhead, crosses Center and 

Bench Creeks, and leads to an old roadhouse building. From there, an unmaintained trail continues up the 

east side of Lynx Creek to the collapsed mine buildings (Hoekzema and Sherman, 1983). 

 In 1981, the U.S. Bureau of Mines located the massive sulfide outcrop and reopened, mapped, and sampled the upper adit (Hoekzema and Sherman, 1983). Average grades of samples are 2.5 percent copper, 0.1 

percent zinc, 0.01 ounce of gold per ton, and 0.3 ounce of silver per ton. Samples assayed 0.002 to 4.4 percent copper, trace to 0.41 percent zinc, a trace to 0.116 ounce of gold per ton, and a trace to 0.75 ounce of 

silver per ton (Jansons and others, 1984). 

Production notes:

 

Reserves:

 Reserves are estimated at 6,000 tons of ore containing 300,000 pounds of copper, 12,000 pounds of zinc, 

1,800 ounces of silver, and 60 ounces of gold (Hoekzema and Sherman, 1983). 

Additional comments:

 Although this copper deposit was one of the earliest lode discoveries in the Moose Pass-Hope District, the 

Ready Bullion remains the only copper prospect in the district (Tuck, 1933).

Gangue minerals: Calcite, quartz 

Geologic description:

 The deposit consists of auriferous, sulfide-bearing, quartz-calcite veins that fill fractures in a shear zone in 

slate of the Valdez Group of Late Cretaceosu age. The zone is 5 to 6 feet wide and extends S80E between 

two pale-greenish porphyritic dikes (Johnson, 1912). Much of the quartz is coarsely crystalline and is accompanied by a small amount of calcite, along with arsenopyrite, galena, sphalerite, and gold. The vein material is weathered and decomposed and has been traced about a hundred feet. The vein dips steeply south, 

nearly vertically. A narrow streak of fault gouge lies along the hanging wall at the shear zone. The gold is 

free-milling or in the arsenopyrite and galena. Specimens from the outcrop contain visible free gold 

(Johnson, 1912). 

 The workings on this prospect consist of trenches and7 a 90-foot adit with 23 feet of winzes, a 12-foot 

crosscut, and a 15-foot shaft (Johnson, 1912). The adit collapsed in 1911 (Martin and others, 1915).

Geologic description:

 Lynx Creek drains an area underlain by sedimentary rocks of the Valdez Group of Late Cretaceous age 

and by mafic dikes that intrude the strata (Nelson and others, 1985). For most of its length, Lynx Creek 

flows in a steep, narrow canyon filled with glacial till, glacial-fluvial gravels, and avalanche debris. Placer 

gold occurs in both the main channel and in benches. The deposits consist of poorly stratified and sorted, 

partly cemented gravels. Most of the production has come from the lower 15 feet of gravel that rests on 

bedrock, although gold also occurs near the mouth of the creek (Janson and others, 1984). Along with gold, 

native copper nuggets have been found in this creek. Production has totaled 7,692 ounces of gold (Cobb 

and Tysdal, 1980).

Workings/exploration:

 Mining methods have included pick and shovel along with both hydraulic and mechanical operations. In 

1905-06, a 600-foot-long underground timbered tunnel was driven from East Fork Sixmile Creek to the upSR157 
Alaska Resource Data File 

Page 320 

per part of Lynx Creek. From there, the gravel was dumped into a 25-foot shaft, run through sluice boxes in 

the tunnel, and the tails deposited into East Fork Sixmile Creek (Paige and Knopf, 1907). Hydraulic mining began in 1915 and continued sporadically until 1980 (Jansons and others, 1984). Small-scale suction 

dredgers are currently (2000) working this creek ( C. S. Huber, oral communication, 2000). 

Production notes:

 Total gold production through 1980 is estimated at 7,692 ounces of gold (Cobb and Tysdal, 1980). Production from 1975 to 2000 is estimated at less than 200 ounces (C. S. Huber, oral communication, 2000). 

Reserves:

 The U.S. Bureau of Mines estimated 5,000 cubic yards of gold-bearing gravels having a grade of 0.015 to 

0.02 ounce of gold per yard (Jansons and others, 1984).

Gangue minerals: Quartz 

Geologic description:

 The host rock at the Brewster mine is slate and graywacke of the Valdez Group of Late Cretaceous age 

(Cobb and Tysdal, 1980). Bedding of the sedimentary country rock strikes S20W. 

 This deposit consists of discontinuous sulfide-bearing pods and stringers of quartz that are localized along 

a fault that strikes N15 to20E and dips vertically. The hanging wall of the fault is slate and the footwall is 

graywacke. The quartz in the wider pods is coarsely crystalline and includes small cavities lined with interlocking quartz crystals. The sulfide minerals are sparse and include chalcopyrite, galena, sphalerite, and pyrite. Some specimens contain visible gold, and select ore yields some free gold on panning (Wimmler, 

1926). 

 Workings consist of a 65-foot adit and a 10-foot drift. A small prospector mill was erected on the site in 

1926.

 Workings consist of a 65-foot adit and a 10-foot drift. The adit bears N20W and the drift bears N70W 

(Wimmler, 1926). A small prospector mill was erected on the site in 1926. The mill consisted of a laboratory-size jaw crusher, an Ellis Independence ball mill, and an amalgamator. A two-horsepower gasoline 

engine provided the power to run the mill. 

 No assay results are reported, although in 1926 ten tons of ore was estimated to contain $150 of gold 

(Wimmler, 1926) or about 5 to 10 ounces of gold (Jansons and others, 1984). 

 The U.S. Bureau of Mines searched for the prospect in 1980 and 1982 but did not find it (Hoekzema and 

Sherman, 1983).

Geologic description:

 The mine is in the Contact Fault zone; this major thrust fault juxtaposes the Valdez Group of Late Cretaceous age with the Orca Group of Tertiary age. The Contact Fault zone formed 65 million to 35 million 

years ago and ranges from 1 to 6 miles wide. Within this zone are numerous discrete shears. The general 

trend of the Contact Fault is northeast, but the strike of individual shears may vary widely (Nockleberg and 

others, 1994). 

 The country rock at the prospect consists of Valdez Group schistose sandy slate that strikes S30W and 

dips 80W (Cobb and Tysdal, 1980). The deposit consists of closely grouped quartz lenses and stringers 

that parallel the schistosity of the country rock in strike and dip. The width of the quartz lenses ranges from 

4 to 59 inches, and the maximum exposed length of any lens or stringer is about 15 feet. The area of quartz 

veins is about 200 feet in length and has an apparent width of at least 15 feet (Johnson, 1914 [B 592-G, p. 

236]). 

 The workings on this prospect consist of a single 100-foot adit, a 15-foot-long open cut, and several prospect pits. The U.S. Bureau of Mines collected 11 samples that contained less than 0.005 ounce of gold per 

ton. Other results included a 9-foot-wide chip sample containing 0.086 ounce of gold per ton and a 2-footwide chip sample of a quartz vein containing 0.374 ounce of gold per ton (Jansons and others, 1984). There 

is no reported production, although a test shipment of ore was made (Johnson, 1918 [B 662-C, p. 183-

192]).

Geologic description:

 The Thomas-Culross mine is within the Contact Fault zone, a major thrust fault that juxtaposes the Valdez Group of Late Cretaceous age with the Orca Group of Teriary age. The Contact Fault zone formed 65 

million to 35 million years ago and ranges from 1 to 6 miles wide. Within this zone are numerous discrete 

shears. The general trend of the Contact Fault zone is northeast, but the strike of individual shears may 

vary widely. 

 The country rocks at the mine consist of sheared Orca Group greenstone, which is rehealed by quartz 

veins that contain arsenopyrite, chalcopyrite, galena, pyrrhotite, sphalerite, and gold. Slate and graywacke 

outcrop about 50 feet north of the portal. The shear zone is traceable for about 900 feet and strikes N10E 

with a vertical dip (Johnson, 1914 [B 592-G, p. 235-236]). The quartz veins within the zone range from 1 

to 14 inches wide and show banding; some arsenopyrite is disseminated in the surrounding wall rock 

(Johnson, 1914 [B 592-G, p. 235-236]). The extensive workings on the property were developed over a 

period of about 30 years. There are a total of 720 feet of adits and drifts, along with a 180-foot raise. A 

1,350-foot-long aerial tramway connected the mine to a 10-foot Chilean mill (Jansons and others, 1984). 

Estimated production from this mine is 62 ounces of gold and 52 ounces of silver (Jansons and others,

Geologic description:

 Sediments of the upper Kenai River contain minor amounts of gold in a section of the river that runs from 

Cooper Creek to Schooner Bend. The metasedimentary bedrock in the area is mapped as Valdez Group of 

Late Cretaceous age (Cobb and Tysdal, 1980). Tysdal (1978 [MF-880-B]) reported that production has 

come, mainly, from just below Cooper Creek where the river has incised about 190 feet into a glaciolacustrine delta. At this site, most of the gold is fine flakes found in point bars and in bedrock fractures. Coarser 

gold, flat but not flaky, has been introduced into the river gravels from Cooper Creek. Tysdal (1978 [MF880-B]) estimated production at less than 769 fine ounces. The U.S. Bureau of Mines estimated production 

at less than 200 ounces (Jansons and others, 1984).

Kenai River about a mile below Cooper Creek. A small bucket line dredge operated during 1911 and 1912. 

Production grade from this operation was 0.004 ounce of gold per cubic yard. The dredge operation was 

not economic. Prospecting using dozers and drilling occurred between 1935 and 1956. Only recreation 

panning has occurred recently. 

 The U.S. Bureau of Mines collected three point bar gravel samples just above Schooner Bend that assayed 

from 0.0135 to 0.0449 ounce of gold per cubic yard (Jansons and others, 1984). Jansons and others (1984) 

estimated total production at less than 200 ounces of gold. 

Production notes:

 Tysdal (1978 [MF-880-B]) estimated production at less than 769 fine ounces. The U.S. Bureau of Mines

Geologic description:

 Cooper Creek is 10 miles long and occupies a narrow bedrock canyon nearly to its junction with the Kenai 

River. Bedrock in the area is slate and graywacke of the Valdez Group of Late Cretaceous age (Nelson and 

others, 1985). 

 Near its mouth, Cooper Creek has cut through stratified gravels of a glacial delta deposit of the Kenai 

River valley. A bench gravel deposited by Cooper Creek on the east side of the stream is between 100 and 

200 feet above the current creek level (Moffit, 1906). The gold content of the glacial delta gravels was low, 

but the Cooper Creek bench gravels averaged about $0.40 per cubic yard (with gold at $20.67 per ounce) 

(Cobb and Tysdal, 1980 ). Cooper Creek bench gravels are 8 to 10 feet thick and are composed of lenses of 

pebbly gravel resting on a sand and clay false bedrock. 

 Even richer bench gravels in the canyon lay on bedrock and contained both coarse and fine gold. The 

largest reported nugget produced from the canyon bench gravels was worth $3.80 (gold at $20.67) 

(Johnson, 1912). 

 Gravels of the active stream channel are loose and easily handled and composed of pebbles of black slate 

and graywacke interspersed with some boulders of fine-grained felsic dike rocks (Hoekzema and Sherman, 

1983). Boulders larger than 3 feet are rare; most boulders are between 1.5 to 3 feet. The stream gravels of 

the both the canyon and the delta have been worked and produced gold. The stream gravels vary considerably in thickness and, in general, are richer in the canyon than near the mouth (Johnson, 1912). 

 The gold is derived from three sources: from the delta deposits that flank the stream flat, from the auriferous glacial and fluvioglacial deposits in the glaciated valley of Cooper Creek, and to a slight extent, probably by post-glacial erosion of gold-bearing lodes in the bedrock of the valley (Johnson, 1912). The gold is 

small, flat, heavy, and not flaky (Johnson, 1912). Gold fineness is 85 percent. Gravel concentrates also 

contain pyrite, arsenopyrite, and magnetite (Johnson, 1912).

Workings/exploration:

 Between 1899 and 1917, creek gravels were worked by hand placer methods and hydraulic mining, both 

in the canyon and on the flat at the lower end of the creek (Johnson, 1912). Only minor production has occurred since. 

 Hydraulic operations were in progress in 1911 on the stream flat at the mouth of the creek. On account of 

the low stream gradient, a Ruble elevator with a 48-foot body, 10 feet wide, and a 12-foot expansion at the 

lower end was installed. The gold-saving attachments consisted of four sluice boxes, 12 feet long by 4 feet 

wide, set on a grade of 8 inches to the box length. The three lower boxes were set with steel-capped 

wooden cross riffles, 4 inches by 2 inches by 4 feet in size, 2 inches apart with 1-inch spaces between the 

steel straps (Johnson, 1912). Water for hydraulicking was obtained from Stetson, and two other nearby 

creeks by an upper ditch 4 miles long, a lower ditch 1.75 miles long, and 1,300 feet of flume. Two No. 2 

Hendy giants with 4-inch nozzles were available, but only one giant with a 5-inch nozzle operating under a 

200-foot head was in use in June 1911 (Johnson, 1912). The usual operation was to strip the soil down to 

the gravel layer and then to wash all the gravel down to the false bedrock over the elevator. Most of the 

gold was caught in the upper boxes. 

 The U.S. Bureau of Mines collected four 0.1-cubic-yard samples from the bench and bar deposits near the 

mouth of Cooper Creek. These contained 0.0018 to 0.019 ounce of gold per cubic yard (Jansons and others, 1984). 

 Current mining, consisting of small-scale suction dredging in the active stream channel, occurs intermittently at and just below Cooper Creeks juncture with Stetson Creek. 

Production notes:

 Moffit (1906) reported that most of the pay from Cooper Creek was taken from a single claim in a single 

year and a profit of 14 pounds of gold was made that year. 

 The U.S. Bureau of Mines estimated total production to have exceeded 1,000 ounces, of which less that 

50 ounces has been produced since 1975 (Jansons and others, 1984). 

Reserves:

 The U.S. Bureau of Mines indicated that only limited quantities of unmined gravel remain (Jansons and 

others, 1984).

Geologic description:

 Stetson Creek occupies a steep, narrow valley with a bedrock gorge developed along its lower section. 

Bedrock is mapped as Valdez Group of Late Cretaceous age (Nelson and others, 1985). The placer section 

extends from the confluence of Stetson and Cooper Creeks upstream for about 1.5 miles (Tysdal, 1978 

[MF-880-B]). Gravel deposited below a series of falls is reported to contain coarse gold (Jansons and others, 1984). Bench gravels along the lower creek just above its confluence with Cooper Creek are as much 

as 50 feet thick and moderately stratified and have a high clay content. In the 1950's high bench deposits 

near the confluence with Cooper Creek were hydraulically mined. Suction dredging has occurred sporadically since that time. 

 Total production is estimated to be less than 300 ounces of gold (Jansons and others, 1984). Two samples 

from the stream channel contained a trace to 0.0043 ounce of gold per cubic yard (Jansons and others, 

1984).

Workings/exploration:

 Historically, work on this creek has consisted of small hydraulic operations and hand mining. In more 

recent time, small-scale suction dredges have worked the active stream channel. Gold recovered in the 

creek consists of both coarse nuggets as heavy as about 2 ounces and fine gold (Cobb and Tysdal, 1980). 

Total production is estimated to be less than 300 ounces of gold (Jansons and others, 1984). Two samples 

from the stream channel of Stetson Creek contained a trace to 0.0043 ounce of gold per cubic yard (Jansons 

and others, 1984). 

Production notes:

 Cobb and Tysdal (1980) estimated total production from this creek as less than 769 fine ounces. Jansons

Site type: Prospect 

ARDF no.: SR181 

Latitude: 60.4531 Quadrangle: SR B-8 

Longitude: 149.6717 

Location description and accuracy:

 This prospect is located on the northeast side of Kenai Lake, 2.5 miles southeast of Quartz Creek at an 

elevation of about 1,450 feet. It is in the NW1/4 section 8, T. 4 N., R. 2 W., of the Seward Meridian. This 

is location 64 of Tysdal (1978 [MF-880-A]) and location S-236 of Jansons and others (1984). This location 

is accurate to within 300 feet. 

Commodities: 

 Main: Sb 

 Other: Au 

Ore minerals: Pyrite, pyrrhotite, stibnite 

Gangue minerals: Quartz 

Geologic description:

 The K and T prospect consists of a fractured and altered felsic dike averaging 2 feet wide and traceable 

for at least 500 feet along strike. The dike strikes N5W and dips 70E. Williams (1952) described the dike 

as being siliceous and containing large amounts of pyroxene. It is recemented by quartz-sulfide veins. Sulfides occur as disseminated grains of stibnite and pyrite and as massive stringers of stibnite (Hoekzema and 

Sherman, 1983). The dike intrudes slate and sandstone of the Upper Cretaceous Valdez Group of Late Cretaceous age (Nelson and others, 1985). The country rock strikes N30E and dips 60NE (Williams, 1952). 

The age of the dike is unknown, but similar dikes 15 to 25 miles east of this location have been dated as 

Tertiary (Nelson and others, 1985). 

 Workings on the prospect consist of surface trenching and sampling. Two samples collected in 1952 contained from 1.7 percent to 4.38 percent antimony and no precious metals (Williams, 1952). Samples collected by the U.S. Bureau of Mines in 1980 contained from 38 ppm to 4.38 percent antimony (Hoekzema 

and Sherman, 1983). 

Alteration:

 The felsic dike is reported to be altered, but the alteration is not described (Hoekzema and Sherman, 

1983). 

Age of mineralization:

 Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.

Longitude: 149.6610 

Location description and accuracy:

 Crescent Creek placer mine is located in T. 5 N., R. 2 W., of the Seward Meridian. The creek flows generally north from Crescent Lake into Quartz Creek, which flows into Kenai Lake. The placer extends for 

about half a mile from the mouth of the creek to about 1.5 miles below Crescent Lake. The map location in 

the NE1/4 section 29 marks the center of the area where most of the mining has occurred. This is location 

P-83 of Jansons and others (1984). This location is accurate to within 300 feet. 

Commodities: 

 Main: Au

Ore minerals: Gold 

Gangue minerals: 

Geologic description:

 Crescent Creek occupies a fairly steep-walled, narrow, avalanche-debris-filled valley. The creek descends 

in a series of steps; auriferous gravels were deposited below each drop. The gravels are clay-rich and contain numerous boulders as much as 3 feet in diameter. Bedrock in the Crescent Creek drainage is metasedimentary rock of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). 

 Gold is disseminated throughout the gravels but is concentrated on bedrock. Bench gravels contain 

anomalous (higher) gold values. Gold occurs as flakes and is fine in the lower part of the creek,but both 

coarse gold and nuggets have been found in the upper section (Jansons and others, 1984). Production has 

been estimated at less than 500 ounces of gold, of which as much as 200 ounces have been produced since 

1975 (Jansons and others, 1984).

creek since 1978 (Jansons and others, 1984). Numerous prospect pits have been dug on the alluvial fan below the lower canyon. Suction dredging has been tried with some success on the upper portion of the creek. 

Small-scale suction dredging has occurred intermittently up through 2001. Gold panning is popular near the 

Crescent Creek campground. No permit is required for panning there. 

 Production is estimated at less than 500 ounces of gold, of which as much as 200 ounces have been produced since 1975 (Jansons and others, 1984). Jansons and others (1984) estimated production grades of 

0.015 ounces of gold per ton. 

 The U.S. Bureau of Mines collected three samples from the lower portion of the creek; they yielded from 

0.01 to 0.03 ounce of gold per cubic yard (Jansons and others, 1984). The section sampled has since been 

mined.

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The prospect consists of quartz stringers and pods as much as 6 inches wide in a 2- to 4-foot-wide shear 

zone. The zone strikes N10E and dips 70E (Hoekzema and Sherman, 1983). The host rock is slate and sandstone of the Valdez Group of Late Cretaceous age (Cobb and Tysdal, 1980). The host rock strikes N18E 

and dips vertically (Martin and others, 1915). Mineralization consists of abundant arsenopyrite and lesser 

amounts of chalcopyrite, galena, pyrite, sphalerite, and gold. Gold occurs free in the quartz and in the sulfide minerals (Martin and others, 1915). The sulfide mineralization appears to pinch out completely in the 

adit (Hoekzema and Sherman, 1983). 

 Workings on the prospect consist of a 5- by 30-foot open cut and a 28-foot-long adit at its north end 

(Hoekzema and Sherman, 1983). Two samples assayed 3.5 ounces of gold per ton and 10.3 ppm gold along 

with 3,500 and 6,500 ppm arsenic, respectively (Hoekzema and Sherman, 1983). The first sample was a 4-

Longitude: 149.4131 

Location description and accuracy:

 The mine is located on Porcupine Creek at an elevation of 1,000 feet and about 3 miles from trailhead at 

the Primrose Creek campground (Primrose Landing). It is in the NW1/4 section 35, T. 3 N., R. 1 W., of the 

Seward Meridian. This is location 81 of Cobb and Tysdal (1980) and location S-214 of Jansons and others 

(1984). This location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Au 

 Other: Ag 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite, pyrrhotite, sphalerite, sphalerite, stibnite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The bedrock at the mine is the slate and graywacke of the Valdez Group of Late Cretaceous age (Cobb 

and Tysdal, 1980). The bedrock strikes N17W and dips vertically (Martin and others, 1915). The mineralization consists of quartz-sulfide stringers and veins in a shear zone that strikes N30E and dips nearly vertically (Martin and others, 1915). The veins range from less than 1 inch to 3.2 feet wide and consist of 

quartz, calcite, arsenopyrite, chalcopyrite, galena, gold, pyrite, stibnite, and sphalerite (Cobb and Tysdal, 

1980). Workings at the site reportedly consist of three levels totaling 450 feet (Byram, 1932). Only the adit 

at the creek level is open. 

 Grab samples from the portal of the upper adit contained 1.572 and 1.166 ounces of gold per ton and 0.6 

ounce of silver per ton (Hoekzema and Sherman, 1983). The adit was collapsed when the portal was sampled. Production from the mine consisted of numerous test shipments of 12 to 15 tons that contained a total 

of 659 ounces of gold and 138 ounces of silver (Hoekzema and Sherman, 1983).

 In 1911, development consisted of surface trenching and a 22-foot-long adit (Martin and others, 1915). In 

1912, the Primrose Mining company was formed; it developed two adits and a 75-foot inclined shaft. The 

mine was sporadically operated from 1913 to 1932. Three levels of workings were developed totaling 450 

feet (Byram, 1932). 

 One of three cabins is still standing. There was a mill on the creek below the cabin. A road was constructed from Kenai Lake to the mine; it is currently the Primrose Creek Trail and is still passable by allterrain vehicles (ATVs). Grab samples from the upper portal assayed 1.572 and 1.166 ounces of gold per 

ton and 0.6 ounce of silver per ton (Hoekzema and Sherman, 1983). 

 Production from the mine consisted of numerous test shipments of 12 to 15 tons that contained a total of 

659 ounces of gold and 138 ounces of silver (Hoekzema and Sherman, 1983). This is recorded production 

that can be substantiated. 

Production notes:

 Recorded production for the mine was 659 ounces of gold and 138 ounces of silver but reported production was 4,000 ounces of gold by 1931 (Jansons and others, 1984; Burnette, 1932). 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 1,300 tons of ore containing 1.42 ounces of gold per 

ton and 0.6 ounce of silver per ton (Jansons and others, 1984). 

Additional comments:

 Burnette (1932) and Byram (1932) are unpublished company reports available at the Alaska State Office, 

BLM, from the minerals department. 

 Jansons and others (1984) described the site as being on Porcupine Creek at an elevation of 1,000 feet in 

the NW1/4 of section 35 T. 3 N., R. 1 W.. Tysdal (1978 [MF-880-A]) also located the site in section 35, T.

Geologic description:

 Porcupine Creek occupies a deep, narrow, bedrock-walled canyon along most of its course; a small alluvial fan is developed along its lower portion. Gold is disseminated throughout the gravels and concentrated 

on bedrock. Bench gravels also contain anomalous gold values. Gold occurs as flakes and is fine in the 

lower part of the creek, but nuggets and coarse gold has been found in the upper section (Jansons and others, 1984). Bedrock in the Porcupine Creek drainage is metasedimentary rock of the Valdez Group of Late 

Cretaceous age (Nelson and others, 1985). 

 Production has been estimated at less than 25 ounces of gold (Jansons and others, 1984). Two samples

Location description and accuracy:

 This placer is located in T. 4 N., R. 1 E., sections 16, 17, and 18 and S1/2 section 13, T. 4 N., R. 1 W. of 

the Seward Meridian. From its headwaters this creek flows westwardly into Trail Creek. The lower 2 miles 

of the creek has produced placer gold; upstream, in another 2-mile section of the creek, the stream gravels 

contain small amounts of gold. The map location is in the center of the lower canyon, in SE1/4 section 18. 

This is location 163 of Cobb and Richter (1972), location 175 of MacKevett and Holloway (1977), location

Geologic description:

 Bedrock in the drainage is slate and sandstone of the Upper Cretaceous Valdez Group (Nelson and others, 

1985). Most of the Falls Creek valley is narrow and steep sided. From its headwaters, Falls Creek descends 

in a series of steps. The uppermost section descends rapidly along a bedrock canyon below which is a relatively gentle portion with a narrow flood plain. Another canyon area begins just below the Falls Creek mine 

(lode) and continues to within a mile of its junction with Trail Creek. Below the second canyon a broad alluvial fan has developed. 

 Small amounts of gold have been found in the silty gravels a half mile above the Falls Creek mine 

(SR206) and in the alluvial fan gravels below the lower canyon (Jansons and others, 1984). Coarse gold has 

been recovered by suction dredges in the lower canyon.

Workings/exploration:

 Martin and others (1915) reported that all gold recovered had been taken from low benches in the canyon 

in the lower part of the creek and at the mouth of the canyon; they reported that the amount of gold in the 

canyon small, not sufficient to pay wages on pick and shovel work. In 1911, the gravel in the flats along 

Falls Creek between Kenai and Lower Trail Lakes was prospected by drilling. Twenty holes were drilled; 

depth to bedrock ranged from 10 to 23 feet. No definite pay streak was located (Martin and others, 1915). 

Drilling and prospect pits were dug in the 1950's on the alluvial fan below the lower canyon (Jansons and 

others, 1984). A small, mechanised operation worked alluvial gravel near the mouth of the lower canyon in 

1980 without significant success. Suction dredging has occurred in the lower canyon area during each year 

since at least 1977 (Jansons and others, 1984). 

 In 1995, a mining claimant unsuccessfully attempted to patent the BBK #2, a 9-acre placer mining claim 

in the lower canyon. This was a small suction dredge operation that recovered coarse nuggets. 

 The U.S. Bureau of Mines collected two 0.1-cubic-yard samples that yielded 0.0022 and 0.0077 ounce of 

gold per cubic yard. A dredge sample near the Falls Creek mine (SR206) yielded only traces of mercurycoated gold (Jansons and others, 1984). Two suction dredge samples collected by the mining claimant for 

the patent examination at the BBK #2 yielded .075 and .028 ounces of gold per hour. 

 An estimated 400,000 cubic yards or better of auriferous gravels are present in the alluvial deposits below 

the lower canyon (Jansons and others, 1984). 

Production notes:

 The U.S. Bureau of Mines has estimated total production to be between 200 and 300 ounces (Jansons and 

others, 1984). 

Reserves:

 An estimated 400,000 cubic yards or better of auriferous gravels are present in the alluvial deposits below

Additional comments:

 Carl Persson and Carol S. Huber conducted a mineral patent examination in 1995 and concluded that no 

discovery within the meaning of the 1872 Mining Law had been made. The patent application was subsequently dropped. A patent report is available at the Chugach National Forest office in Anchorage, Alaska.

Geologic description:

 The rock at the mine consists of a sheared quartz vein that ranges between 1.5 and 5 feet wide; it averages 

2.5 feet wide (Martin and others, 1915). The vein strikes N60E and dips 80N. It is exposed for 300 feet 

above the main adit (a 200-foot-long adit at an elevation of 1,680 feet ) and can be traced along strike for 

about a mile to the 5,000 foot elevation where there is another adit (65 feet long). At an elevation of 5,000 

feet, the vein is 2.5 inches wide. The vein is cut twice by well-defined north-south vertical faults that are 

exposed in the main adit. The country rock consists of slate of the Valdez Group of Late Cretaceous age that 

strikes N30-40E and dips 80W (Nelson and others, 1985; Hoekzema and Sherman, 1983). Metallic minerals are concentrated along fractures in the vein and consist of arsenopyrite, chalcopyrite, galena, pyrite, and 

sphalerite; gold is also present (Martin and others, 1915). Nine grab samples collected from the lower adit 

assayed between a trace and 0.14 ounce of gold per ton and 0.02 to 0.73 ounce silver, along with as much as

and others, 1915). One nearly vertical vein is 15 inches wide and has been traced for 75 feet along its 

N80W strike. The other vein has a width of 4 to 8 inches. Both carry arsenopyrite and were prospected for 

gold. Workings include several open cuts and surface stripping (Hoekzema and Sherman, 1983). The 

Lakeside prospect consists of a 4- to 10-inch-wide quartz vein that strikes north and dips 50E (Martin and 

others, 1915). Minor arsenopyrite and pyrite occur in this vein. Workings on this prospect consist of surface stripping only (Hoekzema and Sherman, 1983). There are no assay results reported in the literature for

Longitude: 149.3106 

Location description and accuracy:

 The mine is located in the NE1/4 section 29, T. 5 N., R. 1 E., of the Seward Meridian, on the north side of 

Grant Lake; the workings extend into the south half of section 20, T. 5 N., R 1 E., in the C-7 quadrangle. 

The workings are accessible from Moose Pass by the Grant Lake trail that begins either at the railroad 

bridge on the west shore of Upper Trail Lake or half a mile south of the railroad bridge on the west shore of 

Upper Trail Lake. (The public is not allowed to walk across to the trail (northern entrance) on the railroad 

bridge. The southern entrance to the trail is accessed by boat.) The mine camp is at an elevation of 700 

feet. The mine workings are about half a mile north-northeast of the camp between elevations of 1,500 and 

1,600 feet. This is location 36 of Cobb and Richter (1972), location 45 of MacKevett and Holloway 

(1977), location 66 of Cobb and Tysdal (1980), and location S-231 of Jansons and others (1984). Cobb and

Gangue minerals: Quartz 

Geologic description:

 The deposit at this mine consists of quartz veins in interbedded slate and graywacke of the Valdez Group 

of Late Cretaceous age (Cobb and Tysdal, 1980). The veins occur in three orientations. One set generally 

parallels the north-northwest strike of the country rock and dips about 70 west. This set of veins contains 

pods and lenses within a shear zone that follows bedding. The hanging wall of the veins is slate, and the foot 

wall is graywacke. The veins range from 12 to 36 inches wide and average about 16 inches. The strike 

length varies, but in the adit at 1,540 feet elevation, this vein was more than 100 feet long. Ore minerals include arsenopyrite, chalcopyrite, galena, and pyrite; gold is also present. 

 The second set of veins strikes roughly east-west and dips 80S. These veins range in width from less than 

a foot to more than 5 feet. A majority of the material mined came from these veins. They are hosted in 

graywacke and are truncated on both ends by left lateral faults (Hoekzema and Sherman, 1983). Samples 

collected by the U.S. Bureau of Mines in 1980 assayed as much as 1.11 ounces of gold per ton (Hoekzema 

and Sherman, 1983). 

 The third set of veins strikes northwest and dips 65 NE. These veins appear to be discontinuous and barren (Hoekzema and Sherman, 1983).

Workings/exploration:

 The mine workings consist of three adits, at elevations of 1,500,1,540, and 1,600 feet. The 1,500-level 

adit is 12 feet long and follows a quartz vein that pinches out at the face. The 1,540-level adit is the main 

working. It is 170 feet long and has two 30- to 40-foot-long crosscuts that follow the east-west-trending 

veins. The western crosscut is stoped to the surface (Hoekzema and Sherman, 1983). The 1,600-foot adit is 

about 40 feet long and follows the northwest-trending vein (Hoekzema and Sherman, 1983). 

Samples collected by the U.S. Bureau of Mines in 1980, assayed as much as 1.11 ounces of gold per ton 

(Hoekzema and Sherman, 1983). Sampling by the U.S. Forest Service as part of a patent examination 

showed sporadic gold grade as much as 2.10 ounces per ton, interspersed with barren samples. 

Production notes:

 Production is estimated at 972 ounces of gold and 123 ounces of silver (Jansons and others, 1984). 

Reserves:

 The proven reserves at this mine are reported to be 270 tons of ore having a grade of 0.78 ounce of gold 

per ton and 0.2 ounce of silver per ton (Hoekzema and Sherman, 1983). The U.S. Bureau of Mines suggested that this deposit has a moderate potential for development as a small mine. 

 The mine was examined both by a private consulting geologist and by a government mineral examiner as 

part of the patent process. U.S. Government mineral examiners concluded in 1993 that mineralization exposed to that date would not support a small-scale mining operation. The private consulting geologist suggested that further work could define a down-dip extension of the known deposit. 

Additional comments:

 There are abundant references to this mine in the literature, but most of them refer only to ongoing work 

and give no details.

Gangue minerals: Calcite, quartz 

Geologic description:

 The host rock in the mine area is slate and sandstone of the Valdez Group of Late Cretaceous age (Nelson 

and others, 1985). The mineral deposit consists of a quartz vein along a shear zone that strikes northeast 

and dips vertically. The zone formed during or after folding of the surrounding slate and graywacke 

(Hoekzema and Sherman, 1983). On the surface, the vein has been traced for more than 1,500 feet. The 

width of the zone is from 5 to 48 inches wide, the average width is 25 inches (Johnson, 1915). The zone is 

terminated on the east side of the workings by a northeast-trending fault (Hoekzema and Sherman,1983). 

The zone consists of crushed and sheared country rock with numerous lenses and stringers of vuggy quartz 

that contains gold, arsenopyrite, galena, sphalerite, and calcite (Johnson, 1915). 

 The mine produced 1,273 ounces of gold and 206 ounces of silver from 1935 to 1941 (Hoekzema and 

Sherman, 1983). Grab and chip samples collected from the workings and surface exposures contained from 

trace to 65 ppm gold and from 1.6 to 19.5 ppm silver (Hoekzema and Sherman, 1983).

Workings/exploration:

 The workings on the property are on four levels: 4,170, 4,320, 4,450, and 4,550 feet elevation. Extensive 

stoping has occurred on the upper three levels, and the lowest level was used mainly for haulage (Hoekzema 

and Sherman, 1983). The deposit was discovered in 190, and development started in 1910-11 with the installation a 5-stamp mill and a 630-foot aerial tram. The mine, owned by Kenai Alaska Gold Company since 

1910, produced 1,852 ounces of gold and 428 ounces of silver from 1911 to 1916 (Hoekzema and Sherman, 

1983). The mine was reopened in 1935 by the Crown Point Mining Company and produced 1,273 ounces of 

gold and 206 ounces of silver from 1935 to 1941 (Hoekzema and Sherman, 1983). Grab and chip samples 

collected from the workings and surface exposures contained from trace to 65 ppm gold and from 1.6 to

1,852 ounces of gold and 428 ounces of silver from 1911 to 1916 (Hoekzema and Sherman, 1983). The 

mine was reopened in 1935 by the Crown Point Mining Company and produced 1,273 ounces of gold and 

206 ounces of silver from 1935 to 1941 (Hoekzema and Sherman, 1983). Production totalled 3,145 ounces 

of gold and 634 ounces of silver (Hoekzema and Sherman, 1983). 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 30,000 tons containing 0.363 ounce of gold per ton and 

0.1 ounce of silver per ton (Hoekzema and Sherman, 1983).

Site type: Mine 

ARDF no.: SR206 

Latitude: 60.4295 Quadrangle: SR B-7 

Longitude: 149.2784 

Location description and accuracy:

 The mine is located on Falls Creek at an elevation of 2,100 feet. It is situated near the north boundary of 

the NE1/4 section 21, T. 4 N., R. 1 E., of the Seward Meridian. This is location 72 of Cobb and Tysdal 

(1980) and location S-224 of Jansons and others (1984). This location is accurate to within 300 feet. 

Commodities: 

 Main: Ag, Au 

 Other: Pb, Zn 

Ore minerals: Arsenopyrite, chalcopyrite, galena, gold, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The mine worked a quartz-calcite vein in a shear zone that also contains gouge. The vein is between 8 

inches and 4 feet wide within a 5-foot-wide shear zone that strikes N50E and dips northeast. The host rock 

consists of tightly folded slate and graywacke that strike north to northeast and dip 75 to 90E (Brooks, 1911 

[B 480-B, p. 32]). Nelson and others (1985) mapped this area as shale and graywacke of the Valdez Group 

of Late Cretaceous age. 

 The vein is composed of massive white quartz with a minor amount of calcite. Arsenopyrite is the principal sulfide in the wall rock and in the vein. Other sulfides include chalcopyrite, galena, pyrrhotite, pyrite, 

and sphalerite. Brooks (1911 [B 480-B]) noted that gold appeared to be concentrated in a bluish quartz. 

 Recorded production totalled 65 ounces of gold and 13 ounces of silver (Hoekzema and Sherman, 1983). 

Alteration:

 

Age of mineralization:

 Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age. 

Deposit model:

Production Status: Yes; small 

Site Status: Inactive 

Workings/exploration:

 Workings total about 860 feet of adit, drift, and winze. Hoekzema and Sherman (1983) reported that the 

workings were inaccessible; however, the portal below the falls was opened in the early 1990's by the current mining claimants. It is only a few feet above the creek level. Improvements consisted of two 2-stamp

mills, a Chilean mill, and a crusher powered by a Pelton water wheel operating under 80-foot head of water 

from Falls Creek (Brooks, 1911 [B 480-B, p. 32]). The remains of a ball mill can be seen several hundred 

feet upstream from the stamp mills. The 3.5-mile-long mine road was usable by all-terrain vehicles (ATVs) 

in 2000; the road begins at Crown Point, across the highway from the Trail River campground road. 

 The gold was reported to be free milling and averaged between $30 and $40 to the ton in gold (gold at 

$20.67 per ounce) (Brooks, 1911 [B 480-B]). A 6-foot chip sample collected by the U.S. Bureau of Mines 

from the vein exposed on the surface assayed 0.09 ounce of gold per ton and 0.07 ounce of silver per ton 

(Jansons and others, 1984). 

Production notes:

 Total recorded production is 65 ounces of gold and 13 ounces of silver (Hoekzema and Sherman, 1983). 

Some of this may have come from the Skeen-Lechner mine, SR207, because both were operated by the 

same company.

Site type: Mine 

ARDF no.: SR207 

Latitude: 60.4382 Quadrangle: SR B-7 

Longitude: 149.2780 

Location description and accuracy:

 The mine is located approximately 3 miles east of the Seward Highway on the north side of Falls Creek at 

an elevation of 3,200 feet. On the 1994 USGS Seward B-7 topographic map it is misnamed the Falls Creek 

mine. It is situated in the NE1/4 section 16, T. 4 N., R. 1 E., of the Seward Meridian. This is location 71 of 

Cobb and Tysdal (1980) and location S-225 of Jansons and others (1984). This location is accurate to 

within 300 feet. 

Commodities: 

 Main: Au 

 Other: Ag, Pb 

Ore minerals: Arsenopyrite, galena, gold, pyrite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The deposit at the mine consists of two quartz veins that have been developed by three levels of workings 

at elevations of 2,140, 3,210, and 3,260 feet. The upper vein occupies a fracture in massive graywacke 

mapped as part of the Valdez Group of Late Cretaceous age (Nelson and others, 1985); it strikes N15W and 

dips 45E. The upper vein is 20 to 45 inches wide and is surrounded by 1 to 4 inches of fault gouge (Martin 

and others, 1915). The lower vein lies about 90 feet southwest of the upper vein and strikes N45W and dips 

65NE. It measures 46 inches in width at the upper tunnel and varies from 1 to 4 feet in the lower adit. Both 

veins are offset by a series of N55E-trending shear zones that dip vertically. The movement of the faults is 

right lateral, and the throw is about 30 feet (Hoekzema and Sherman, 1983). 

 Both veins are composed of shattered white quartz with faint indications of secondary banding. A small 

amount of calcite occurs with the quartz. Sulfide minerals are of arsenopyrite, pyrite, and galena. Sulfides 

are also found disseminated in the wall rock and tend to be concentrated on vein margins (Martin and others, 1915). Native gold is associated with arsenopyrite and galena. 

 Workings total about 2,000 feet (Jansons and others, 1984). Most of the production came from the lower 

vein. Total production was 1,786 ounces of gold and 502 ounces of silver (Hoekzema and Sherman, 1983). 

Samples collected from the workings and surface exposures contained from trace to 360 ppm gold, and 

trace to 30 ppm silver (Hoekzema and Sherman, 1983).

Workings/exploration:

 The property was discovered in 1907, and development started on the 3,210 level in 1910 (Jasper, 1958). 

By 1912, when the property was abandoned, about 1,000 feet of workings were completed. In 1938, the 

Falls Creek Mining Company (owner of the Falls Creek mine and mill ) acquired the property, and intermittent development occurred through 1950 (Jasper, 1958). The workings total about 2,000 feet, including 

1,259 feet of drifts and stopes on the lower vein and 741 feet of drifts and stopes on the upper vein 

(Hoekzema and Sherman, 1983). Samples collected from the workings and surface exposures contained 

from trace to 360 ppm gold and from trace to 30 ppm silver (Hoekzema and Sherman, 1983). 

Production notes:

 Production totalled 1,786 ounces of gold and 502 ounces of silver (Jansons and others, 1984). Some of 

this may have come from the Falls Creek mine, SR206. 

Reserves:

 The U.S. Bureau of Mines estimated a resource of 10,000 tons containing 0.82 ounce of gold per ton and 

0.3 ounce of silver per ton (Hoekzema and Sherman, 1983).

Geologic description:

 The occurrence consists of an iron-stained, laminated, siliceous mudstone that is locally cut by quartfeldspar veinlets near a granite contact. Traces of chalcopyrite and as much as 2 percent pyrite occur as disseminations and fracture fillings in the mudstone (Kurtak and Jeske, 1986). The mudstone is Orca Group of 

early Teriary age (Nelson and others, 1985). The granite belongs to the informally named Nellie Juan granite, which has been dated as 35.5 +/-0.9 my old (Lanphere, 1966). 

 One random chip sample across siliceous mudstone and quartz-feldspar veinlets contained 96 ppm copper 

(Kurtak and Jeske, 1986). A sample collected by Tysdal (1978 [MF-880-A]) contained 300 ppm chromite, 

85 ppm copper, 100 ppm nickel, 50 ppm tin, and 90 ppm zinc.

Geologic description:

 The prospect consists of a single, 20- to 28-inch-wide, mineralized quartz vein. The center of the vein is a 

6- to 11-inch-wide zone of massive to semi-massive sulfide minerals consisting of arsenopyrite, galena, pyrite, sphalerite, and gold (Grant, 1909). The vein strikes N52W and dips 67W; it is exposed for about 15 

feet (Grant, 1909). The bedrock in this area slate and graywacke of the Orca Group of early Teriary age 

(Nelson and others, 1985). 

 An 8-foot-long open cut was driven on the vein in 1908. Six samples were collected from the open cut; 

three were taken across the outer part of the vein, and three were taken across the central sulfide zone. Assays of the outer quartz zone averaged 0.5 ounce of gold per ton, and the inner sulfide zone averaged 2.5 

ounces of gold per ton (Grant, 1909).

Commodities: 

 Main: Au, Cu 

 Other: 

Ore minerals: Chalcopyrite, gold, native copper, pyrite, pyrrhotite 

Gangue minerals: Quartz 

Geologic description:

 The deposit consists of auriferous, sulfide-bearing quartz veinlets hosted in sheared greenstone and 

sheeted basalt of the Orca Group of early Teriary age (Cobb and Tysdal, 1980). The main shear zone is 

approximately 20 feet wide; it strikes N35-80E and dips 60-70NW. The shear zone is cut by a series of 

smaller shear zones that trend west to northwest and dip steeply. These smaller zones vary from 1 foot to 

more than 5 feet in width and contain quartz veinlets. They are intermittently exposed along the bluff for 

approximately 200 feet. The bluff is the footwall of the main shear zone. Sulfide minerals, primarily pyrrhotite and pyrite, occur as dissemination and stringers within the shear zone. Traces of gold, chalcopyrite, 

and native copper also occur in the zone. Four random chip samples and two chip samples collected from 

the prospect by the U.S. Bureau of Mines in the early 1980's contained between 21 ppm and 2.0 percent 

copper and as much as 3.32 ppm silver (Kurtak and Jeske, 1986).

Ore minerals: Chalcopyrite, pyrrhotite 

Gangue minerals: Epidote, quartz 

Geologic description:

 The prospect is hosted in a moderately sheared, medium-grained greenstone lens within fine-grained 

greenstone and finely laminated, tuffaceous sedimentary rock. Nelson and others (1985) identified the 

greenstone as Orca Group of early Teriary age. Several shear zones, as much as 10 feet wide, cut the greenstone. They are part of a larger shear zone system that trends north-northeast and dips nearly vertically. 

This system is about half a mile wide and 5 miles long (Nelson and others, 1985). Chalcopyrite and pyrrhotite occur as blebs in a basalt dike and within quartz-epidote veins. The relationship between shearing 

and mineralization is unclear. Sulfide minerals are found in numerous quartz veins in shears zones and impregnating the country rock (Cobb and Tysdal, 1980). Pyrrhotite is the dominant sulfide; traces of chalcopyrite and pyrite are also present. 

 Two adits were driven along shear zones; the 10-foot-long south adit is at an elevation of 860 feet, and the 

63-foot-long north adit is at an elevation of 830 feet. The U.S. Bureau of Mines collected a total of nine 

samples, seven from the adits and two from within 80 feet east of the south adit. They contained between 

75 ppm and 0.24 percent copper and as much as 0.7 percent nickel Kurtak and Jeske, 1986).

Site type: Mine 

ARDF no.: SR236 

Latitude: 60.3123 Quadrangle: SR B-3 

Longitude: 147.7749 

Location description and accuracy:

 The mine is located on the southeast shore of Drier Bay about half a mile southwest of Barnes Cove at an 

elevation of about 500 feet. This is in the NE1/4 section 31, T. 3 N., R. 10 E., of the Seward Meridian. 

This is location 230 of Cobb and Tysdal (1980) and location S-50 of Jansons and others (1984). This location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Cu 

 Other: Zn 

Ore minerals: Chalcopyrite, covellite, cubanite, pyrrhotite, sphalerite 

Gangue minerals: Epidote, quartz 

Geologic description:

 According to Kurtak and Jeske (1986), the mine workings expose an iron-stained shear zone that trends 

N15W and dips 40 to 80 NW. It averages 4 feet in width. The host rock is sheared greenstone that exhibits 

various degrees of chloritization (Kurtak and Jeske, 1986). Nelson and others (1985) mapped this area as 

Orca Group of early Tertiary age. Massive sulfide lenses composed mainly of pyrrhotite and chalcopyrite as 

much as 6 inches thick occur throughout the greenstone. They can be traced for about 240 feet along strike 

(Kurtak and Jeske, 1986). Other minor sulfide minerals include cubanite, covellite, and sphalerite. A 60-

foot-long adit at 518 feet elevation was driven S10E along the shear zone. Massive sulfide mineralization 

consisting mostly of pyrrhotite with some chalcopyrite occurs along both the hanging wall and footwall. 

Samples from this zone contained from 280 ppm to 13 percent copper along with trace amounts of silver 

and gold. Samples from the open cut at 453 feet elevation contained 0.15 percent to 1.6 percent copper 

(Kurtak and Jeske, 1986). 

Alteration:

 Kurtak and Jeske (1986) reported the greenstone shows various degrees of chloritization. 

Age of mineralization:

 Tertiary or younger; the occurrence is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 Workings at the mine consist of two adits and an open cut. A 60-foot adit at 518 feet elevation strikes 

S10E. A 6-foot adit at 435 feet elevation strikes N60W. The open cut is at 560 feet elevation. The U.S. 

Bureau of Mines visited the prospect in the early 1980's and found both adits but only one open cut (Kurtak 

and Jeske, 1986). Improvements consisted of a small wharf, two cabins on the beach, a wire tram, and a trail 

leading to the workings. Eight samples from the adits contained from 280 ppm to 13 percent copper along 

with trace amounts of silver and gold (Kurtak and Jeske, 1986). 

Production notes:

 In July 1908, the Russell Ball Copper Company shipped a small amount of copper ore (Johnson, 1918 [B 

662-C, p. 184, 216-217]). 

Reserves:

 Chugach Alaska Corporation estimated a reserve of 5,900 tons of ore containing 2.4 percent copper, 0.3 

ounce of silver per ton, and 0.03 ounce of gold per ton (Hoyt and Rogers, 2000).

This location is accurate to within 300 feet. 

Commodities: 

 Main: Cu 

 Other: 

Ore minerals: Chalcopyrite, pyrrhotite 

Gangue minerals: Actinolite, chlorite, quartz 

Geologic description:

 The mine workings follow a 60-foot-wide shear zone in massive greenstone and chlorite schist. The zone 

strikes N-S and dips steeply east (Kurtak and Jeske, 1986). Nelson and others (1985) mapped the greenstone and schist as Orca Group of early Teriary age. Post-mineralization basalt dikes are present; these are 

unmetamorphosed and appear unrelated to mineralization (Kurtak and Jeske, 1986). The age of the dikes is 

unknown. 

 The mineralization consists of massive, stringer, and disseminated pyrrhotite and chalcopyrite, mostly in 

the hanging wall of the shear zone (Kurtak and Jeske, 1986). This mineralized zone ranges from 1 to 10 

feet in width (Kurtak and Jeske, 1986). 

 The workings consist of an adit with 245 feet of crosscuts and drifts, two stopes, each about 30 feet high, 

and a water-filled winze of unknown depth (Kurtak and Jeske, 1986). A rough estimate of the stope volume 

suggest that about 330 tons of material was removed (Kurtak and Jeske, 1986). A single 4-foot-wide chip 

sample collected from the adit contained 3.3 percent copper, 0.15 ppm gold, and 3.8 ppm silver ( Kurtak

 The workings consist of 245 feet of crosscuts and drifts, two stopes each about 30 feet high, and a waterfilled winze of an unknown depth (Kurtak and Jeske, 1986). Grant and Higgins (1909) reported an aerial 

tramway, several buildings, a wharf, and a steam plant located near tidewater. A rough estimate of the stope 

volume suggests that about 330 tons of material was removed (Kurtak and Jeske, 1986). A single 4-footwide chip sample collected from the adit contained 3.3 percent copper, 0.15 ppm gold, and 3.8 ppm silver 

( Kurtak and Jeske, 1986). 

Production notes:

 Production is estimated at 330 tons of unknown grade (Kurtak and Jeske, 1986). This estimate was arrived at from the volume of the stope. 

Reserves:

 Inferred reserves are 1,300 tons of ore, containing 3.3 percent copper. A few tons of ore is stockpiled on 

the beach below the prospect (Kurtak and Jeske, 1986).

 The mine is located between the elevations of 300 and 1,100 feet about three-quarters of a mile south of 

Northeast Cove at the head of Drier Bay. It is in the NE1/4 section 32, T. 3 N., R. 10 E., of the Seward Meridian. This is location 25 of Condon and Cass (1958), location 107 of Cobb and Richter (1972), location 

135 of MacKevett and Holloway (1977), location 229 of Cobb and Tysdal (1980), and location S-52 of Jansons and others (1984). This location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Cu 

 Other: 

Ore minerals: Chalcopyrite, pyrite, pyrrhotite 

Gangue minerals: Calcite, quartz 

Geologic description:

 Two major rock types occur at the mine site: a light-gray, aphanitic, intermediate volcanic rock, and a porphyritic, dark gray-green greenstone. Some thin layers of slate are interbedded with the volcanic rock 

(Kurtak and Jeske, 1986). The prospect is within the Nellie shear zone, which is a northeast-trending, nearly 

vertical zone exposed for about 5 miles (Kurtak and Jeske, 1986). The greenstone and slate are Orca Group 

of early Teriary age (Nelson and others, 1985). 

 The mine workings consist of three adits and several open cuts. The mineralization consists of several 

massive sulfide lenses within several shear zones that are from 1 to 10 feet wide. One lens of massive sulfides is 30 feet wide by 40 feet high and consists of massive chalcopyrite and pyrrhotite. This lens is exposed above the upper adit (Grant, 1906). In the middle adit, the mineralization consists of a 1- to 5-footwide shear zone containing 1 to 5 percent disseminated chalcopyrite and pyrrhotite (Kurtak and Jeske, 

1986). 

 Samples from the workings and surface exposures contained from 15 ppm to 1.6 percent copper and from 

less than 1 ppm to 5.1 ppm silver (Kurtak and Jeske, 1986). A one-ton bulk sample shipped in 1911 contained 240 pounds of copper, 2 ounces of gold, and 3 ounces of silver (Kurtak and Jeske, 1986).

Geologic description:

 The prospect consists of a N25E-trending shear zone that dips 75SE, cutting greenstone country rock 

(Johnson, 1918 [B 662-C, p. 217-218]). Nelson and others (1985) have mapped the country rock as Orca 

Group of early Teriary age. The workings on the prospect consist of five open cuts, a 6-foot-deep shaft, and 

a 36-foot adit. At the adit face, the shear zone is 9 feet wide and has a 2-inch-wide band of pyrrhotite and 

chalcopyrite near the footwall (Johnson, 1918 [B 662-C, p. 217-218]). This zone can be traced along strike 

for about three-quarters of a mile. At an elevation of 1,200 feet, a 6-foot-deep shaft exposes a 10-foot-wide 

shear zone containing chalcopyrite (Johnson, 1918 [B 662-C, p. 217-218]). Tysdal (1978 [MF-880-A]) 

summarizes the prospect as a limonite-stained sheared greenstone containing chalcopyrite, pyrrhotite, cubanite, and quartz. Samples collected from the prospect contained from 9 to 150 ppm copper and 25 to 150 

ppm zinc (Kurtak and Jeske, 1986).

Geologic description:

 Nelson and others (1985) mapped bedrock in this area as greenstone of the Orca Group of early Teriary 

age. The prospect consists of a weakly developed shear zone that contains a fine network of quartz-sulfide 

stringers (Johnson, 1914 [B 592-G, p. 237-243]). The shear zone is between 20 to 55 feet wide, but the 

margins are poorly defined; it strikes N15E and dips vertically. The zone is only slightly mineralized as a 

whole, and in some places short lenses of solid or nearly solid sulfide minerals occur in the sheared greenstone (Johnson, 1914 [B 592-G, p. 237-243]). The sulfide minerals consist of chalcopyrite, chalmersite, 

sphalerite, and pyrrhotite (Johnson, 1914 [B 592-G, p. 237-243]). Kurtak and Jeske (1986) reported the 

presence of malachite staining and a trace of native copper. 

 Samples collected from the adit and the surface trenches contained between 50 ppm and 1.3 percent copper and 0.3 to 11 ppm silver (Kurtak and Jeske, 1986).

 Workings on the prospect consist of a 742-foot-long adit at 950 feet elevation, with 160 feet of crosscuts 

and a winze. There are also two surface trenches located at 1,200 feet elevation (Johnson, 1914 [B 592-G, 

p. 237-243]). There is a collapsed cabin below the adit (Kurtak and Jeske, 1986). Samples collected from 

the adit and surface trenches contained between 50 ppm and 1.3 percent copper and from 0.3 to 11 ppm silver (Kurtak and Jeske, 1986). In 1911, a test shipment of ore was sent to the smelter in Tacoma, Washington, but results are not known (Kurtak and Jeske,1986). There are 200 tons of ore on the dump. 

Production notes:

 

Reserves:

 Kurtak and Jeske (1986) reported that 200 tons of ore was stockpiled on the dump in 1911.

Site type: Prospect 

ARDF no.: SR251 

Latitude: 60.4174 Quadrangle: SR B-2 

Longitude: 147.7253 

Location description and accuracy:

 The prospect is located in the S1/2 section 21, T. 4 N., R. 10 E., of the Seward Meridian on the southeast 

side of the south end of Herring Bay between sea level and 110 feet elevation. This is locations 203 and 

204 of Cobb and Tysdal (1980) and location S-76 of Jansons and others (1984). This location is accurate 

to 300 feet. 

Commodities: 

 Main: Cu 

 Other: Zn 

Ore minerals: Chalcopyrite, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Epidote, quartz 

Geologic description:

 The prospect consists of several short adits and a prospect pit that explored thin, discontinuous sulfide 

veins, stringers, and lenses hosted in sheared greenstone of the Orca Group of early Teriary age. Sulfide 

minerals are chalcopyrite, pyrite, pyrrhotite, and sphalerite (Cobb and Tysdal, 1980). A 50-foot adit was 

driven into fractured greenstone healed with quartz, pyrite, sphalerite, and chalcopyrite (Grant and Higgins, 

1909). The prospect pit exposed irregular mineralization consisting of chalcopyrite, sphalerite, and pyrite. 

Epidote stringers occur in the country rock, but there is no well-defined vein or shear zone associated with 

these stringers. 

Alteration:

 Greenstone is altered to epidote. 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 Four workings are described in the literature. Grant and Higgins (1909) described a 25-foot adit that is a 

quarter of a mile south of the camp and a 50-foot adit. Johnson (1918 [B 662-C, p. 212]) described a 30-

foot adit with a 10-foot drift to the north driven at an elevation of 110 feet. He also mentioned a 15-footSR251

wide open cut, west of the 30-foot adit. When the U.S. Bureau of Mines searched for this prospect in the 

early 1980's, they found none of these workings, and they did not collect samples from the area. Improvements on the property were two bunk and mess houses on the beach and a floating dock (Grant and Higgins, 

1909). No other information is available.

Geologic description:

 The prospect consists of a shear zone in slate and graywacke of the Orca Group of early Teriary age; the 

shear zone contains lenses of massive sulfide along with quartz veins (Nelson and others, 1985; Kurtak and 

Jeske, 1986). The shear zone is 3 to 5 feet wide; it trends N20E and dips steeply northwest. The surface 

exposure is strongly iron-stained. Sulfides consist of pyrrhotite, chalcopyrite, and sphalerite that are, along 

with quartz, in fractures and brecciated zones (Kurtak and Jeske, 1986). Workings on the prospect consist 

of a 70-foot-long adit that appears to parallel the trend of the mineralized zone for 55 feet, then crosscuts it. 

A single sample from the adit contained 110 ppm copper and 53 ppm zinc. An 8-foot chip sample collected from the iron-stained shear zone at the mouth of the adit contained 0.37 percent copper and 0.82 percent zinc (Kurtak and Jeske, 1986).

Jeske, 1986). Individual zones as much as 15 feet wide enclose lenses of unsheared greenstone and form an 

aggregate width of 90 feet. The shear zones are traceable for about 6 miles along strike. The sheared rock 

is chloritized greenstone schist that is locally brecciated (Kurtak and Jeske, 1986). The greenstone is 

mapped as Orca Group of early Teriary age (Nelson and others, 1985). Sulfide minerals in the zone are 

chalcopyrite, pyrite, pyrrhotite, cubanite, and sphalerite (Cobb and Tysdal, 1980). Workings on the prospect consist of a 96-foot-deep shaft, an adit with two drifts totalling more than 150 feet, and a 100-foot-long 

open cut near the collar of the shaft. Poy (1926) reported that the mineralization averaged 2.2 percent copper over a width of 18 feet in the underground drifts. Samples from the surface cut contained from 38 ppm 

to 4.0 percent copper and from trace to 6.0 ppm silver. Some ore was shipped from the property in 1908 

(Kurtak and Jeske, 1986). 

Alteration:

 Greenstone has been chloritized. 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 The property was developed by a 96-foot-deep shaft, an adit with two drifts totalling more than 150 feet, 

and a 100-foot-long open cut near the collar of the shaft (Johnson, 1916; Kurtak and Jeske, 1986). Poy 

(1926) reported that the mineralization averaged 2.2 percent copper over a width of 18 feet in the underground drifts. The shaft is currently flooded (Kurtak and Jeske, 1986). Samples from the surface cut contained from 38 ppm to 4.0 percent copper and from trace to 6.0 ppm silver (Kurtak and Jeske, 1986). 

Production notes:

 In 1908, a small but unknown amount of ore was shipped (Kurtak and Jeske, 1986). 

Reserves:

 Poy (1926) inferred a reserve of 85,000 tons of ore containing 1.31 percent copper and 5.4 percent iron. 

Rogers and Hoyt (1999) reported a reserve of 85,000 tons containing 2,040,000 pounds of copper, 425 

ounces of gold and 8,500 ounces of silver. 

Additional comments:

 Patent was applied for in 1924.

 Other: Ag?, Pb, Zn 

Ore minerals: Chalcopyrite, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Chlorite, epidote, quartz 

Geologic description:

 The country rock in the area of the prospect is greenstone and pillow basalt of the Orca Group of early 

Teriary age (Cobb and Tysdal, 1980). The greenstone strikes N20 to 45E and dips nearly vertical. The 

workings consist of two adits that follow a north-trending, 4-foot-wide shear zone that dips nearly vertical. 

The lower adit is at about 640 feet elevation, and the upper adit is at about 1,000 feet elevation. Pyrrhotite 

and chalcopyrite are the dominant sulfides in the zone; pyrite and sphalerite are subordinant. Gangue minerals identified include quartz, chlorite, and epidote (Kurtak and Jeske, 1986). 

 Nine samples collected from all four adits by the U.S. Bureau of Mines contained between 25 ppm and 

3.25 percent copper and from 0.3 to 14 ppm silver. The highest grade copper sample was a 10-foot-wide 

chip sample of a massive sulfide lens that is exposed in the 1,000 foot elevation adit. It contained 3.25 percent copper and 12.4 ppm silver (Kurtak and Jeske, 1986).

lower adit is collapsed; it was 165 feet long (Grant and Higgins, 1909; Kurtak and Jeske, 1986). The upper 

adit is about 75 feet long and has a 15-foot crosscut and a flooded winze of unknown depth (Kurtak and 

Jeske, 1986). There also two short adits west of the main shear zone; they follow another north-trending vertical shear zone. A 28-foot adit is at 1040 feet elevation, and there is a 6-foot adit at the 680 foot elevation. 

Improvements include a small steam sawmill, an electric plant, and a main camp near the beach (Moffit and 

Fellows, 1950). 

 Nine samples collected from all four adits by the U.S. Bureau of Mines contained between 25 ppm and 

3.25 pervent copper and from 0.3 to 14 ppm silver. The highest grade copper sample was a 10 foot-wide 

chip sample of a massive sulfide lens that is exposed in the 1,000 foot elevation adit; it contained 3.25 percent copper and 12.4 ppm silver (Kurtak and Jeske, 1986).

Ore minerals: Chalcopyrite, malachite, pyrite 

Gangue minerals: Epidote, quartz 

Geologic description:

 The prospect consists of three shear zones that strike N50E and dip 65-75S. The shear zones cut greenstone and are cemented by quartz-epidote-sulfide veins (Kurtak and Jeske, 1986). The greenstone is part of 

the Orca Group of early Teriary age (Nelson and others, 1985). Two 10-foot-long adits are driven on two of 

the shear zones, which are about 20 feet apart. An 14-foot-long open cut follows the third shear zone. 

 The southernmost adit follows a 2- to 8-inch-wide quartz vein for 15 feet. The vein contains epidote, pyrite, and a small amount of chalcopyrite. The north adit follows a 6- to 8-inch-wide breccia zone for 12 feet. 

It contains chalcopyrite, malachite, and pyrite. The open cut exposes a 6-inch-wide breccia zone that is cemented by quartz, pyrite, and chalcopyrite. The hanging wall of this zone is silicified for about 2 feet. Random chip samples collected from the adits and surface exposures contained from 200 ppm to 1.9 percent 

copper and from 0.3 to 6.3 ppm silver. The random chip sample containing 1.9 percent copper was from 

greenstone breccia with quartz epidote veins and visible chalcopyrite and a trace of malachite. (Kurtak and 

Jeske, 1986).

Location description and accuracy:

 The prospect is located in the NW1/4 section 35, T. 5 N., R. 10 E., of the Seward Meridian. It is situated 

at sea level on the southwest shore of Disk Island. This is location 92 of Cobb and Richter (1972), location 

120 of MacKevett and Holloway (1977), location 196 of Cobb and Tysdal (1980), and location S-084 of 

Jansons and others (1984). This location is accurate to within a quarter of a mile. This description includes 

other copper-stained breccia zones near the prospect and exposed along the beach for about 2 miles. 

Commodities: 

 Main: Cu 

 Other: 

Ore minerals: Chalcopyrite, pyrite, pyrrhotite 

Gangue minerals: Epidote, quartz 

Geologic description:

 The prospect consists of a 10-foot-long adit driven on a greenstone breccia zone that is as much as 4.5 feet 

wide, strikes N55W, and dips 75E (Johnson, 1918 [B 662, p. 211]). The zone is traceable for about 50 feet. 

It is healed by quartz and epidote and contains as much as 5 percent pyrite and traces of chalcopyrite 

(Kurtak and Jeske, 1986). Several other mineralized zones within greenstone and pillow basalt of the Orca 

Group (of early Teriary age) occur on the south side of Disk Island (Cobb and Tysdal, 1980; Nelson and 

others, 1985). Sulfide minerals in these zones are pyrite, pyrrhotite, and a trace of chalcopyrite, which is 

irregularly distributed throughout the breccia, shear, and fracture zones. The largest of these zones is a 15- 

by 40-foot exposure of intensely fractured pillow flow containing an estimated trace of chalcopyrite and 5 

percent pyrite; the pyrite occurs as blebs, fracture fillings, and fine disseminations. Copper-stained, fractured and brecciated zones are exposed along the beach in this general area for about 2 miles. Nine samples 

collected from the adit and from various zones along the beach contained from 58 ppm copper to 0.43 percent copper and from 50 ppm to 0.81 percent zinc (Kurtak and Jeske, 1986). The adit sample contained the 

highest copper value. 

Alteration:

 Silicification and epidotization are reported, but no details are provided (Johnson, 1918 [B 662, p. 211]). 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Commodities: 

 Main: Cu 

 Other: 

Ore minerals: Chalcopyrite, pyrite, pyrrhotite 

Gangue minerals: Epidote, quartz 

Geologic description:

 The country rock in the area is composed of mafic rock that varies in composition and texture from finegrained greenstone to diabase or gabbro. Some of the gabbro contains pyrrhotite, and a massive pyrite pod 

was found in a diabase dike. The pyrite pod is 0.2 by 2 feet in size. In another area gabbo enclosed a quartz 

pod about 10 feet in diameter that contains pyrrhotite and epidote stringers. Nelson and others (1985) 

mapped the bedrock as Orca Group of early Teriary age. 

 Workings on the prospect consist of a 30-foot-long adit that trends N20W and is a few feet above sea 

level (Richter, 1965). The U.S. Bureau of Mines did not locate the reported adit, so they collected samples 

from the rock in the area. One sample was collected from gabbro and one from greenstone containing pyrrhotite blebs and quartz and epidote veinlets. Each contained less than 100 ppm base metals (Kurtak and 

Jeske, 1986).

Latitude: 60.3524 Quadrangle: SR B-2 

Longitude: 147.6498 

Location description and accuracy:

 The prospect is located on the north side of an unnamed creek that drains into Rua Cove. There are workings present from an elevation of 170 feet to an elevation of 1,200 feet. The prospect is in the NW1/4 section 13, T. 3 N., R. 10 E., of the Seward Meridian. This is location 213 of Cobb and Tysdal (1980) and location S-67 of Jansons and others (1984). This location is accurate to within 300 feet. The mine symbol on 

the 1:63,360-scale B-2 topographic map is this prospect. 

Commodities: 

 Main: Ag, Au, Cu 

 Other: Zn 

Ore minerals: Chalcopyrite, pyrrhotite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 Bedrock at this prospect is greenstone surrounded by shale and graywacke; all thse rocks are part of the 

Orca Group of early Teriary age (Cobb and Tysdal, 1980). The greenstones are cut by a N15E-trending 

shear zone that dips from 60W to 80E but in most places is vertical to 80W (Stefansson and Moxham, 

1946). Massive sulfide bodies consisting of pyrrhotite and chalcopyrite occur within the zone and along the 

walls. Within the zone, greenstone contains disseminated sulfides with lenses of massive sulfides 

(Stefansson and Moxham, 1946). Most of the largest sulfide lens is 30 to 50 feet wide, and parts of it reach 

100 feet wide. The strike length of the largest sulfide lens is about 400 feet. Its down-dip extension determined by drilling is more than 500 feet (Stefansson and Moxham, 1946). A magnetic survey indicated that 

there are two large unexplored anomalies, one to the north and one to the south (Richter, 1965). Both bodies 

are on strike with the deposit. 

 Bedrock exposed in the workings consists of three distinct types of greenstone. The results of a thinsection study by Stefansson and Moxham (1946) indicated that probably the most abundant type is finegrained, greenish to black rock. That rock originally consisted of feldspar microlites, small grains of augite, 

and perhaps some ilmenite. These minerals have been altered to chlorite, prehnite, clinozoisite, and leucoxene. The second type is a blocky dark-gray porphyritic rock that locally shows pillow structures. In thin section this greenstone consists of large phenocrysts of labradorite in a groundmass of altered glass 

(palagonite). The rims of the pillows are glassy. The third type of greenstone is a medium-grained, graygreen rock with a composition of quartz diorite. Euhedral augite is distributed in a groundmass of labradorite or andesite and quartz. 

Alteration:

 Basalt is altered to greenstone. 

Age of mineralization:

 Tertiary or younger; the occurrence is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 Development on the prospect consists of two adits. The main adit at an elevation of 320 feet has a total of 

2,420 feet of drifts and crosscuts. The second adit is 600 feet southeast of the main adit at an elevation of 

170 feet; it is 590 feet long. 

 Several buildings were built on the site over the years, but only one is still standing (Kurtak and Jeske, 

1986). Power was generated onsite by both a water-powered generator and by diesel generators (Kurtak 

and Jeske, 1986). 

 The property was explored by drilling in 1929-30, 1948-49, 1972-73, and 1976. Some drill core remains 

on the site (Kurtak and Jeske, 1986). Geophysical exploration in 1964 by the U.S. Bureau of Mines delineated two untested anomalies (Kurtak and Jeske, 1986). Geochemical surveys were done by Texasgulf in 

1976-77. Sampling and drill results indicated a resource of 1,988,000 tons of ore with a grade of 0.57 percent copper, 42.4 percent iron, 0.005 ounce of gold per ton, and 0.1 ounce of silver per ton. (Kurtak and 

Jeske, 1986). Production consisted of 1,000 pounds of ore shipped for testing in 1909. 

Production notes:

 Grant and Higgins (1909) reported 1,000 pounds of ore shipped for testing. The test shipment contained 

1.68 percent copper, 47.9 percent iron, 31.5 percent sulfur, and 15 percent SiO2 (Grant and Higgins, 1909). 

Reserves:

 Stefansson and Moxham (1946) reported measured reserves are 25,000 tons of 1.25 percent copper and 

indicated and inferred resources of 1.3 million tons of ore at a grade of 1.25 percent copper. Rutledge 

(1953) calculated indicated and inferred resource of 592,000 tons at 1.24 percent copper or 1,988,000 tons 

of ore with a grade of 0.57 percent copper. Additional commodities include 42.4 percent iron, 0.005 ounce 

of gold per ton, and 0.1 ounce of silver per ton (Kurtak and Jeske, 1986). Rogers and Hoyt (1999) estimate 

a reserve for the prospect of 1,320,000 tons of ore containing 1.2 percent copper and 132,000 ounces of silver. 

Additional comments:

 This prospect is owned by Chugach Alaska Corporation.

the portals of the two short adits, contained between less than 0.1 ppm and 28.5 ppm gold (Hoekzema and 

Sherman, 1983). 

Production notes:

 

Reserves:

 The U.S. Bureau of Mines estimated 1,100 tons of ore containing 0.3 ounce of gold per ton and 0.3 ounce 

of silver per ton ( Hoekzema and Sherman, 1983). 

Additional comments:

 The gold to silver ratio in the eight samples collected by the U.S. Bureau of Mines is 1:1 (Hoekzema and 

Sherman, 1983). An indicated resource with a 1:1 gold to silver ratio is suspect.

Location description and accuracy:

 The prospect is on the east shore of Whale Bay at Bebe Point (triangulation station Bebe) about 10 feet 

above the high tide line in the SE1/4 section 14, T. 1 N., R. 7 E., of the Seward Meridian. The Seward A-4 

quadrangle 1:63,360 topographic map (1988 revision) identifies this site as a mine, but there has been no 

production. This is location S-25 of Jansons and others (1984). This location is accurate to within 300 feet. 

Commodities: 

 Main: Au 

 Other: Ag, Cu, Pb, Zn 

Ore minerals: Chalcopyrite, galena, gold, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The deposit consists of auriferous, sulfide-bearing, quartz stringers and lenses as much as 4 inches wide in 

a 2- to 6-foot-wide shear zone that is traceable for 35 feet along its N28E trend. The host rock is silicified 

mudstone that strikes N28E and dips 41NW (Kurtak and Jeske, 1986). Nelson and others (1985) mapped 

bedrock in this area as Orca Group of early Teriary age. 

 Workings on the prospect consist of a 50-foot adit driven on a N28E-trending shear zone that dips 30NW. 

In the adit, the shear zone consists of (from the hanging wall to footwall) a 3- to 4-inch-wide sulfide-bearing 

quartz vein; 0.125 inch of fault gouge; 3 to 4 feet of silicified mudstone breccia that contains approximately 

15 percent quartz veining; and as much as 2 feet of shear gouge. Minerals associated with the quartz veins 

include pyrrhotite, pyrite, chalcopyrite, galena, sphalerite, and gold (Kurtak and Jeske, 1986). Samples collected from the adit and float on the beach assayed as much as 0.727 ounce of gold per ton and 0.3 ounce of 

silver per ton (Kurtak and Jeske, 1986).

Gangue minerals: Asbestos, calcite, quartz 

Geologic description:

 Grant and Higgins (1909) described the prospect as a 370-foot-long adit that followed quart-calcite veins 

in greenstone and slate. The veins contained pyrite, pyrrhotite, chalcopyrite, quartz, and asbestos (Tysdal, 

1978 [MF-880-A]; Grant and Higgins, 1909). Some of the veins were 3 inches thick, and asbestos was perpendicular to the wall of the veins. Bedrock in this area is Orca Group of early Teriary age (Nelson and 

others, 1985). 

 In 1980 and 1981, the U.S. Bureau of Mines examined this area but did not find the adit reported by Grant 

and Higgins (1909) and Tysdal (1978 [MF-880-A]). They sampled barren quartz-calcite veins that contained no asbestos (Kurtak and Jeske, 1986).

Site type: Mine 

ARDF no.: SR301 

Latitude: 60.0149 Quadrangle: SR A-3 

Longitude: 147.9244 

Location description and accuracy:

 This mine is located in the SW1/4 section 9, T. 2 S., R. 9 E., of the Seward Meridian. It is about 0.5 mile 

southeast of Horseshoe Bay at an elevation of 125 feet. This is location 259 of Cobb and Tysdal (1980) and 

location S-3 of Jansons and others (1984). This location is accurate to within 300 feet. 

Commodities: 

 Main: Cu 

 Other: Ag, Au 

Ore minerals: Chalcopyrite, gold, pyrite, pyrrhotite, silver 

Gangue minerals: Quartz? 

Geologic description:

 The deposit at the Duke mine consists of massive sulfide lenses in northeast-striking, interbedded slate 

and graywacke of the Orca Group of early Teriary age (Kurtak and Jeske, 1986). The lenses vary from 4 to 

27 feet wide and have a strike length of as much as 151 feet. The deposit occurs on the northwest limb of a 

shallowly northeast-plunging antiform (Stejer, 1956). The sulfide minerals are mostly pyrite with minor 

amounts of chalcopyrite and pyrrhotite (Stejer, 1956). The typical mineralization consists of a disseminated 

halo of pyrite surrounding massive pyrite with some chalcopyrite (Stejer, 1956). The footwall of the massive sulfide lenses is in many places a slate bed, and the highest grade of copper mineralization is under the 

footwall (Kurtak and Jeske, 1986). 

 Within or near the massive sulfide lenses, the country rock shows varied degrees of silicification, sericitization, and kaolinization (Stejer, 1956). Some faulting occurs that is generally parallel to bedding. Surface 

outcrops located about 100 feet from the shaft indicate that the mineralized belt has a width of 200 to 250 

feet. It appears to be on the same trend as the Duchess (SR302) mineralized zone, which lies 2,400 feet 

north of this deposit (Kurtak and Jeske, 1986). 

Alteration:

 There is strong asymmetric sericite-chlorite alteration associated with the massive sulfide mineralization 

(Rogers and Hoyt, 1999). 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 The initial claims were staked in 1898, and by 1907, a two-compartment shaft had been sunk on the 

property. In 1908, the shaft was deepened to 110 feet, but the site abandoned when the shaft flooded. In 

1918, the shaft was pumped out, and a total of 311 feet of crosscuts and drifts was completed. The property 

was abandoned until 1970, when Northwest Exploration drilled several core holes (Kurtak and Jeske, 1986). 

Production notes:

 An unspecified amount, believed to be small, of production was reported in 1907 (Kurtak and Jeske, 

1986). 

Reserves:

 There are measured reserves of 68,800 tons of ore containing 1.32 percent copper, 0.06 ounce of gold per 

ton, and 0.05 ounce of silver per ton (Kurtak and Jeske, 1986). Indicated reserves are 200,000 tons of ore 

containing 1.32percent copper, 0.06 ounce of gold per ton and 0.06 ounce of silver per ton (Rogers and 

Hoyt, 1999).

Longitude: 147.9194 

Location description and accuracy:

 The mine is located a half-mile east of Horseshoe Bay at an elevation of 380 to 470 feet. This is in the 

NW1/4 section 9, T. 2 S., R. 9 E., of the Seward Meridian. This is location 258 of Cobb and Tysdal (1980) 

and location S-4 of Jansons and others (1984). This location is accurate to within 300 feet; a mine is shown 

at the location on the 1:63,360-scale, A-3 topographic map. 

Commodities: 

 Main: Cu, Pb, Zn 

 Other: 

Ore minerals: Arsenopyrite, chalcopyrite, cubanite, galena, pyrite, pyrrhotite, sphalerite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The mineralized zone at the Duchess mine trends N30E and is parallel to the bedding of the slategraywacke host rock that dips steeply northwest (Stejer, 1956). Nelson and others (1985) have mapped the 

bedrock in this area as Orca Group of early Teriary age. The mine is on the northwest limb of a shallowlydipping, northeast-plunging antiform (Stejer, 1956). 

 The mine workings consist of two major levels with portals at elevations of 380 feet and 470 feet and a 

10-foot prospect adit at an elevation of 630 feet. The underground workings, which were developed from 

1905 to 1918, aggregate about 3,000 feet of drifts and crosscuts and explore the mineralized zone for a distance of 500 feet along strike (Kurtak and Jeske,1986). Lenses of massive sulfides occur throughout the 

workings. They range from a few inches to as much as 60 feet wide and from less than one foot to at least 

490 feet long. The mineralization typically consists of a disseminated halo of pyrite surrounding massive 

pyrite, with some chalcopyrite (Stejer, 1956). Other minor sulfides present include cubanite, sphalerite, 

pyrrhotite, aresenpyrite, and galena (Kurtak and Jeske, 1986). The footwall of the massive sulfide lenses is 

in many places a slate bed; the highest grade of copper mineralization is near the footwall (Kurtak and 

Jeske 1986). Within or near the massive sulfide lenses, the country rock shows varied degrees of silicification, sericitization, and kaolinization (Stejer, 1956). Sixteen samples collected from the 400-foot level contained trace to 1.48 percent copper, 0.1 to 0.8 percent zinc, trace to 0.02 ounce of gold per ton, and 0.4 to 

0.7 ounce of silver per ton (Stejer, 1956). 

Alteration:

 The wallrock alteration of the deposit at the Duchess mine consists of silicification, sericitization, and 

kaolinization. The alteration is zoned; silicification near the hanging wall grades into argillic and sericitic 

alteration toward the footwall (Stejer, 1956). 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Workings/exploration:

 The mine workings consist of two major levels with portals at elevations of 380 and 470 feet and a 10-

foot prospect adit at an elevation of 630 feet. The underground workings, which aggregate about 3,000 feet 

of drifts and crosscuts, explore the mineralized zone for a distance of 500 feet along strike (Stejer, 1956). 

The workings were intially developed in 1905 with all of the production occurring in 1906. From 1907 to 

1916 about 2,850 feet of drift and crosscuts were driven in an attempt to deliniate additional ore bodies. 

Sixteen samples collected from the 400-foot level contained trace to 1.48 percent copper, 0.1 to 0.8 percent 

zinc, trace to 0.02 ounce of gold per ton and 0.4 to 0.7 ounce of silver per ton (Stejer, 1956). 

Production notes:

 The deposit was initially staked in 1899, and by 1905 as much as 300 feet of exploration adits had been 

driven. All of the production from the Duchess mine occured in 1906. Production totalled 215,000 pounds 

of copper from 2,850 tons of ore (Rogers and Hoyt, 1999). 

Reserves:

 Chugach Native Corporation, the current property owner, estimates a reserve of 2,700,000 tons with 3.8 

percent copper (Rogers and Hoyt, 1999).

 Grant and Higgins (1909) reported that the Chicago-Latouche Mining and Power Company installed a 

pipeline and an electric power plant. They were then also engaged in driving an east-southeast adit to intersect a continuation of the Bonanza orebody, which is about 0.6 mile to the north. In 1908, the adit was 

1,400 feet long but had encountered no mineralization. The U.S. Bureau of Mines visited the prospect in 

1984 and 1985; they found the adit but did not enter it because it was flooded and the water was too deep 

(Kurtak and Jeske, 1986).

Ore minerals: Chalcopyrite, cubanite, galena, gold, pyrite, pyrrhotite, silver, sphalerite 

Gangue minerals: Ankerite, calcite, quartz, sercite 

Geologic description:

 The country rock in the mine area consists of a north-trending, interbedded sequence of west-dipping slate 

and graywacke, with graywacke predominating (Kurtak and Jeske, 1986). Nelson and others (1985) 

mapped this rock as Orca Group of early Teriary age. The major structural feature in the mine area is the 

Beatson fault, which cuts slightly across bedding, strikes about N12E and dips (on average) 60W. On the 

footwall of the fault, ore occurs as a massive and disseminated sulfide zone. The highest grade ore occurs 

adjacent to the fault (Kurtak and Jeske, 1986). The ore body is roughly 400 feet wide by 500 feet vertical 

and extends for 1,000 feet along strike. Sulfide minerals consist of pyrite, pyrrhotite, chalcopyrite, cubanite, galena, silver, and sphalerite; gold and silver are also present. Gangue minerals consist of quartz, sercite, and ankerite. The average ore grade was 1.7 percent copper and 0.27 ounce of silver per ton. Total 

production was 5,992,941 tons of ore grading 1.65 percent copper and 0.279 ounce of silver (Kurtak and 

Jeske, 1986). 

Alteration:

 There is strong silicification of the footwall rock . There is chloritic alteration of the hanging wall rock 

(Rogers and Hoyt, 1999). 

Age of mineralization:

 Tertiary or younger; the mineralization is in rocks of the Orca Group of Tertiary age.

Geologic description:

 The prospect consists of a shear zone that trends N29E and dips 75W; it is roughly parallel to the strike 

of the graywacke (Kurtak and Jeske, 1986) Nelson and others (1985) mapped this area as Orca Group of 

early Teriary age. Within the shear zone, pyrrhotite, pyrite, and chalcopyrite occur in a massive zone as 

much as 1 foot wide and in stringer zones as much as 5 feet wide. The mineralization can be traced for 200 

feet along the zone trend. Drag folds affect both the graywacke and massive sulfide stringers associated 

with the shear zone (Hoekzema and Sherman, 1983). 

 Workings on the prospect consist of a 100-foot adit that is mostly submerged at high tide. A shaft was 

sunk on a cliff at 60 feet above high tide; it later flooded (Bateman, 1928). The U.S. Bureau of Mines visited the prospect in 1985 but found no signs of workings (Kurtak and Jeske, 1986). They collected three 

chip samples from the shear zone and one from mineralized graywacke. The samples contained from 0.7

with the graywacke. There is no mineralization associated with the diorite (Kurtak and Jeske, 1986). Several shear zones, as much as 5 feet wide, trend northeast, but most dip more steeply than the graywacke. 

The shear zones, which are confined to the graywacke, contain 1- to 5-foot-wide sulfide-bearing zones consisting of as much as 5 percent chalcopyrite stringers, as much as 2 percent pyrite with minor amounts of 

bornite, and some quartz veinlets and lenses as much as 6 inches wide (Kurtak and Jeske, 1986). Four chip 

samples were collected by the U.S. Bureau of Mines (Kurtak and Jeske, 1986); three samples contained 

0.78 percent, 0.89 percent, and 0.99 percent copper, respectively, and from 2 to 4 ppm silver. One sample 

contained 2.2 percent copper and 8.6 ppm silver.

Geologic description:

 The prospect consists of a zone of iron-stained, sheared greenstone of the Orca Group of early Teriary age 

(Nelson and others, 1985). A 71-foot-long adit was driven to intersect the shear zone. The shear zone is 

30 feet wide; it trends N2E and dips 80E. There is a shallow open cut above the adit. The mineralization 

consists of thin lenses of massive chalcopyrite, pyrrhotite, pyrite, and some bornite. Thin quartz-rich lenses 

within the shear zone also carry sulfide minerals (Kurtak and Jeske, 1986). Two chip samples, 2.5 and 1.5 

feet wide, from the adit contained 1,650 ppm and 0.16 percent copper, and 1,250 and 1,550 ppm zinc. A

Geologic description:

 The prospect is hosted in graywacke near the contact with greenstone. Both units are the Orca Group of 

early Teriary age (Nelson and others, 1985). Three adits were driven to explore the prospect: a 680-footlong adit at the 315-foot elevation, a 70-foot-long adit at the1,000-foot elevation, and a short adit above 

the 1,000-foot elevation (Grant and Higgins, 1909). The first 200 feet of the lower adit cuts greenstone, 

then it crosses a sheared contact into slate. 

 The mineralization consists of quartz-chalcopyrite stringers and disseminated chalcopyrite lenses that occur mainly in shear zones. Mineralization in the 70-foot adit is thin stingers of pure chalcopyrite (Grant and 

Higgins, 1909). Random chip samples collected from the lower adit contained from 35 to 75 ppm copper 

and no precious metals values (Kurtak, and Jeske, 1986). The U.S. Bureau of Mines did not find the other 

two workings that are described in the literature.

 In 1908, four substantial long buildings were built on the property by James Mullins Coal Company. 

Three adits were driven to explore the prospect: a 680-foot-long adit at 315-foot elevation, a 70-foot-long 

adit at the 1,000-foot elevation, and a short adit above 1,000-foot elevation (Grant and Higgins, 1909). 

Random chip samples collected from the 680-foot adit by the U.S. Bureau of Mines in 1981 contained from 

35 to 75 ppm copper and no precious metals values (Kurtak, and Jeske, 1986).

Geologic description:

 The host rock at the Copper Queen mine is graywacke and greenstone of the Orca Group of early Teriary 

age (Nelson and others, 1985). Bedrock strikes generally northwest and dips 42SW (Kurtak and Jeske, 

1986). Two types of sulfide mineralization occur at the mine. The first is a 1- to 4-foot-wide quartz vein 

that contains chalcopyrite, pyrrhotite, pyrite, and sphalerite. The other is a brecciated massive sulfide in 

sheared graywacke and greenstone containing pyrrhotite, pyrite, and chalcopyrite (Grant and Higgins, 

1909). The shear zone contained a fault gouge and breccia unit that is from 3 inches to 1 foot wide. Sulfides within the zone consist of massive pyrite, 5 to 10 percent chalcopyrite, 1 to 2 percent covellite, and 

traces of malachite (Kurtak and Jeske, 1986). Samples collected from the upper adit by the U.S. Bureau of 

Mines contained as much as 7.5 percent copper and between 2.3 and 9.0 ppm silver (Kurtak and Jeske, 

1986).

 The workings at the mine consisted of three adits. A lower adit at the 40-foot elevation was driven for 

1,100 to 1,200 feet; it did not reach the vein type mineralization that outcrops uphill (Johnson, 1918 [B 662-

C, p. 219-220]). The middle adit is at the 398-foot elevation and that is about 450 feet long including drifts 

and crosscuts (Grant and Higgins, 1909). The upper adit is at the 535-foot elevation and is 85 feet long. 

Only the adit at the 535-foot elevation is still accessible; it was driven along a shear zone that strikes S25E 

and dips 60W (Kurtak and Jeske, 1986). 

 Improvements associated with the mine consisted of steam plant, office, and living quarters (Kurtak and 

Jeske, 1986). Samples collected from the upper adit by the U.S. Bureau of Mines contained as much as 7.5 

percent copper and between 2.3 and 9.0 ppm silver (Kurtak and Jeske, 1986). Production from the mine is 

57 pounds of copper from 110 tons of ore that was shipped in 1917 (Kurtak and Jeske, 1986). 

Production notes:

 Patton Mining Company reported that the mill on the property ran from March 15 to September 1, 1917, 

and processed 110 tons of ore containing 57 pounds of copper (0.026 percent copper) (Kurtak and Jeske, 

1986).

Additional comments:

 Internal reports by Kennecott Copper Corporation in 1924 stated that the Patton Mining Company, whicht 

ran the property in 1917, was more or less a promotion scheme (Kurtak and Jeske, 1986). 

 The mine is also known as the Happy Jack Copper Mining and Development Company.
