. Areas near Fairbanks, Juneau, and Nome are responsible for most of Alaska's historical and current gold production. Nearly all of the large and many of the small placer gold mines currently operating in the US are in Alaska. Six modern large-scale hard rock mines operate in Alaska in 2008; four of those are gold-producing mines (an additional gold mine suspended production in late 2007). There are also some small-scale hard rock gold-mining operations. Alaska currently produces more gold (in 2007: 673,274 troy oz from lode mines, and 53,848 troy oz from placer deposits) than any state except Nevada

Juneau district

In 1880 a local inhabitant, Chief Kowee, revealed to prospectors Joe Juneau and Richard Harris the presence of gold in what is now named Gold Creek in Silver Bow Basin. The city of Juneau was founded there that year. The strike sparked the Juneau gold rush which resulted in the development of many placer and lode mines including the largest, in their time, gold mines in the world: the Treadwell complex of lode mines on Douglas Island (across a narrow sea channel from Juneau) and the AJ lode mine, in Juneau itself.

Over 7 million ounces of lode gold and 80,000 ounces of placer gold have been recovered from the Juneau district.

Admiralty district

Most of the gold recovered from the Admiralty mining district (which consists of Admiralty Island) is a by product of silver and base metal mining. The Alaska Empire underground lode mine recovered gold from quartz veins in metamorphic rock

s. Discovered and staked in the 1920s, production of about 20,000 tonnes of 0.25 ounce-per-ton gold ore occurred in the mid-1930s. The Funter Bay underground lode mine produced about 500 thousand tonnes of copper-nickel-cobalt ore, without gold, from a Mesozoic gabbro-norite pipe. No significant placer mining was done on Admiralty. About 500,000 ounces of gold, almost all from the currently-operating Greens Creek lode silver mine, have been recovered from the Admiralty district.

Numerous lode and placer prospects and mines exist in the district. Major production came from underground lode mines exploiting gold-in-quartz veins.
Apex-El Nido mine

The Apex-El Nido produced perhaps 50,000 ounces of gold from a mile of underground workings exploiting polymetallic quartz veins.
Hirst-Chichagof mine

From 1922 to 1933 the Hirst-Chichagof produced 133,000 ounces of gold and 33,000 ounces of silver from polymetallic quartz veins assaying nearly 1 ounce of gold per ton. There are over a mile of underground workings, reaching 2000 feet (609.6 m) below the surface. Significant reserves remain, which have attracted exploration efforts in the 1980s and 1990s.
Chichagof mine

The Chichagof mine opened in 1905 and by 1942 had yielded 660,000 ounces of gold and 195,000 ounces of silver from quartz veins assaying over 1 oz gold per ton. There were several miles of workings on 5 levels. Six shafts reached a maximum of 2750 feet (838.2 m) below sea level.
Between 1981 and 1988 several thousand feet of new workings were dug, and engineering and environmental studies were done, but the project was abandoned.

 and Ketchikan districts. Many small lode deposits were located in the late 1890s and early 1900s. The most significant lode producer was the Sumdum Chief, which was discovered in 1889 and operated until exhausted in 1903. 24,000 ounces of gold were extracted from two quartz veins averaging ore of about 0.39 ounces per ton of both gold and silver. The mine reached a depth of 1200 feet (365.8 m) and had a ten-stamp mill. In Windham Bay, a cluster of mineral claim holdings were consolidated in the 1920s; the Jensen mine was the most productive of these, producing about 50 ounces of gold. Several aerial tramways, thousands of feet long, connected various adits and mills.

, and smaller islands, as well some mainland, in the southernmost-part of Alaska.
Numerous historical lode mines and prospects for base metals, uranium, rare earth elements (REE's), iron, and platinum group elements (PGE's), as well as gold exist in the Ketchikan district. Major gold production came from underground lode mines exploiting: gold-bearing quartz veins in metamorphic rocks (such as the Gold Standard, Sea Level, Dawson, Golden Fleece, and Goldstream mines); skarns (at the Jumbo and Kassan Peninsula copper-gold mines); zoned mafic-ultramafic plutons, as at the Salt Chuck silver-gold-copper-PGE mine; and VMS deposits such as Niblack.

A high-yielding mine in Ketchikan District is the Golden Fleece Mine, located about 0.2 mile north of the north end of James Lake on Prince of Wales Island, latitude: 55.152179, longitude: -132.056635. The mine was most active from 1901 to 1905.

, and extends to the crest of the Brooks Range. Discovery of placer gold in 1906 was quickly followed by lode discoveries. Most of the placer-producing creeks drain the area of lode mineralization. The district produced about 48,000 ounces of placer gold and 17,000 ounces of lode gold.
Little Squaw Creek

Little Squaw Creek drains an area cut by many auriferous veins. Some of the placers in the basin are exceptionally rich. By 1916 most of the shallow placers were playing out so miners shifted their interest to the placer drift mines (underground operations). The most notable of these is the Little Squaw Bench, including the Mellow Bench. Approximately 29,000 ounces of gold were recovered averaging 1.0 oz/cubic yard of gold in the gravels with spikes of up to 4.6 oz/cubic yard. Some individual nuggets were over 10 ounces. In 2010, gold production resumed with mining of the placer deposits by the Gold Rich Mining Company.
Little Squaw and Mikado lodes

In 1909 to 1915 development and underground gold mining occurred at the Little Squaw, with a few hundred feet of workings built and a few dozen ounces of gold recovered. The nearby Mikado mine enjoyed similar efforts around 1913. In the 1960s , 1970s and 1980s additional work was done. These later efforts probably recovered more than 10,000 ounces of gold.
Significant efforts resumed in 2006, and are ongoing, to explore the Little Squaw placer and lode deposits.

. Mining continues today in the district.
Much of the district is underlain by bedded Paleozoic rocks, a schist belt extends along the southern foothills of the Brooks Range. Cretaceous plutons intrude metamorphic rocks in the southern part of the district. Pleistocene ice sheets from the Brooks Range and cirque glaciers in the Ray Mountains covered much of the higher elevations. Glaciers are now restricted to the highest cirques of the Brooks Range.
Nolan Creek

Miners produced 135,000 ounces of gold from Nolan Creek between 1904 and 1999. Some of the placer gold is mined by underground methods in frozen gravels. A 42-troy ounce nugget, Alaska's twentieth-largest, came from Marys Bench on Nolan Creek. Placer mining activity continues, with a reserve of 114,760 ounces of gold reported in 2000.
Hammond River

Mining occurred on the Hammond River, a tributary of the Koyukuk River, from about 1900 to at least 2000. Exact production is unknown, it is estimated at about 80,000 ounces.

A rich, deep channel was struck beneath the Hammond River in 1912, and during the following 4 years, over 48,000 oz gold were produced, including a 138.8-oz nugget. (Pringel, 1921; T.K. Bundtzen, written communication, 1999)
Much of the gold was coarse: the third (146 troy oz.), fourth (139 troy oz.), 14th (61 troy ounces), and 17th (55 troy ounces) largest gold nuggets in Alaska were found on the Hammond River between Discovery claim and Vermont Creek a distance of 4 miles.
Only the richest ground was possible to mine as the Hammond River was one of the most remote placer districts in North America until 1975 when the Dalton Highway for the Alaskan Pipeline project was completed.
Historically the Hammond River is one of the largest gold producers in the Koyukuk district. Gold was discovered on the Hammond River, just above the lower canyon mouth, about 2 miles upstream from the Koyukuk River. In the early years, attempts were made to mine the modern stream gravels. At the mouth of Swift Creek a wing dam was built to divert the river for mining, but numerous cobbles and small boulders made the venture unprofitable. Approximately 500 ounces was recovered with pick and shovels in Summer of 1902. Later, shafts sunk 66 feet to bedrock at the discovery site were reported to show the presence of gold in paying quantities. The majority of the gold production on the Hammond came out of the deep channel as early miners were unable to deal with the water and cobbles in the present river channel.

The Hammond River contains deep channel, bench, and modern stream placers.
Much of the Hammond River gold is of the coarse nugget variety. Several nuggets weighing from 45 to 59 oz were found in the early days. In 1914 a 138.8 oz nugget (fourth largest in Alaska) was found in a mud-filled crack on bedrock near Gold Bottom Gulch (Engineering and Mining Journal, 1915, p. 1021; T. Bundzten, personal communication, 1999).

In 1914,on No. 4 Above, Hammond River (Goldbottom Gulch), J. C. Kinney and partners picked up nuggets from bedrock valued at about $20,000; one nugget, the second largest ever found in Alaska, was worth $2600. The rest of the dump when sluiced yielded a little less than the value of the "pickings." (Engineering and Mining Journal, 1914, p. 1062 Vol. 98 No. 24. (Gold at $20.00 per ounce.)

Placers on Slisco bench, an ancient buried channel of Hammond River near Vermont Creek on the west side of the present Hammond River contain a measured resource of 31,099 oz gold with grades of up to 0.3 oz/cy. Inferred resources on the same bench range from 50,000 to 150,000 oz. (2002) . Other benches of Hammond River between Discovery Claim and Slisco Bench have similar potential but have not been systematically prospected with modern technology.

Hughes District

The Hughes district includes the basin of the lower Koyukuk River (below the Kanuti). Much of the area is a swampy, lake-studded lowland, from which rises rounded hills to elevations of several thousand feet.

Placer mines in the Zane Hills on Bear Creek, a tributary of the Hogatza River, are the biggest source of gold from the district. Placer deposits clustered near the village of Hughes and Indian Mountain are the other significant source of placer gold from the district. The district has produced about 245,000 ounces, with traces of copper, lead, zinc, tin, silver and platinum.

Melozitna District

On the northern side of the Yukon River, between the Melotizna and Ray rivers, most of the district is rolling ridges with upmost elevations over 5000 feet (1,524 m), where now-gone Pleistocene cirque glaciers developed. Placer gold was discovered in 1907, but activity was sporadic and poorly recorded. About 10,000 ounces of gold, with significant by-product tin, was won from placer deposits by the 1960s.

. The Illinois Creek lode gold-silver mine exploited a shear-hosted gold deposit which was partly expressed as color anomalies visible from aircraft. Located on State of Alaska land, it was discovered in the 1980s. In February 1996 a feasibility study was completed, with the deposit estimated to contain about 350,000 ounces of gold and 2,500,000 ounces of silver. Construction began the next month, but was halted by winter conditions in November. By then, with the development uncompleted and six-million more than the total mine construction-and-operating budget of 26-million dollars already spent, USMX, the mining company that owned Illinois Creek, was millions of dollars in arrears on invoices and short on cash. New financing allowed construction to resume in 1997; the mine poured its first gold in June 1997. In 1998 the company entered bankruptcy. In 1999 the State of Alaska assumed control of the mine. A mine-to-reclaim arrangement between the state and a newly-involved mining contractor resulted in the reclamation and closure of the mine by 2005. A bond is in place to provide environmental monitoring for 30 years.

Ruby-Poorman District

The Ruby-Poorman District produced nearly a half million ounces of gold, all from placer mines. Some of the largest gold nuggets found in Alaska are from the district, which lies south of the Yukon River. The placers are mostly deeply buried, and most were originally worked with shafts and drifts. Dozens of creeks in the district were mined, many more bear gold prospects. Cassiterite

. In July, 1914 Jay Livengood and N.R. Hudson discovered gold on Livengood Creek. Hundreds of people arrived in the district the following winter. A post office existed at Livengood from 1915 to 1957. Only a few dozen people live at Livengood today, some only seasonally. A variety of creeks in the district were mined. Many gold lode occurrences are known and exploration continues for open pittable lode deposits. Over 500,000 ounces of gold have been recovered from placers in the district.

Early development and production was from relatively shallow pay in tributaries of Livengood Creek. By 1939, large, deeply buried (80 to 110 feet), thawed, bench placer deposits on the northwest limit of Livengood Creek valley were defined. The pay streak varied from 100 to 1000 feet (304.8 m) wide and was at least 6 miles (9.7 km) long. Gold reserves of over 1 million ounces were defined by drilling prior to 1940. A dredge operated near the town of Livengood in 1940, 1946 and probably other years.

Alaska's 12th-largest (73 troy ounces) and 16th-largest (56 troy ounces) nuggets were found in the district, on Dome Creek.

The district was and is a major producer of gold from both placer and lode deposits: placers have produced over 8 million troy ounces (250 tonnes) of gold, lodes have yielded over 4 million ounces.

Goodpaster district

Only a few thousand ounces of gold from placer mines, and a few hundred ounces from lode gold mines were produced from the Goodpaster district before the discovery of Pogo. The district is west of the Fairbanks and south of the Circle district.
Pogo mine (operating)

The recently discovered and built Pogo mine is located on a hillside above the Goodpaster River, about 85 miles (136.8 km) south-east of Fairbanks, Alaska. The deposit was discovered in 1994 by the Sumitomo companies on land owned by the State of Alaska. A private 49 miles (78.9 km) gravel road and power line now connects the mine to the Richardson Highway corridor near Delta Junction. The mine is an underground operation that exploits two large (several-meters thick) and high-grade (averaging almost 0.5 ounces of gold per ton of ore) gold-bearing quartz veins. Approximately half of the tailings are returned underground, the rest are disposed of on the surface. The mine was developed, and originally operated, by Teck-Cominco, the same company operating the world's largest zinc mine; the Red Dog mine

 in northwest Alaska. Sumitomo Metal Mining (a non-operating partner and part-owner of the Pogo deposit since discovery) bought Teck-Cominco's share of the mine in 2009 and is now the operator. The first gold dore bar at Pogo was poured on February 12, 2006. 190 people were employed at the mine in 2007.

In early 2007 Pogo contained reserves of 5.6 million ounces of gold in ore grading 0.41 opt gold. Projected mine life is ten years.

Gold was first discovered in the Chicken Creek drainage in 1896, 10 years after the gold discovery on the Fortymile River. The F.E. Company, a subsidiary of the U.S. Smelting Refining & Mining Co., acquired most of the claims during the 1940s and dredged 2 miles (3.2 km) of the creek from 1959 to 1967. Since then, several family operations have mined on the creek. It is estimated that over 100,000 ounces of gold has been produced from the Chicken Creek drainage.

Marshall-Anvik District

The Marshall and Anvik districts produced about 124,000 ounces of gold and minor amounts of platinum, mainly from Wilson Creek.
The district has the Bering Sea to the west, the Yukon River to the south, and the Iditarod and Kaiyuh districts to the east.

Aniak District

About 220,000 ounces of gold produced, mainly from the Tuluksuk River (where the town of Nyac is located) and Crooked Creek basins and with lesser production from Wattamuse and other creeks scattered around the district. Mining continues at present, but reserves are not known. Cinnabar (mercury sulfide) occurs in many of the placer mines in this district, most notably at Cinnabar Creek.
Donlin Creek (feasibility stage)

Placer mining began on benches and tributaries on the east side of Crooked Creek and its tributary Donlin Creek in 1910; a family-scale placer-mining operation continues today. Granitic dike swarms cutting the shales and sandstones of the Kuskokwim Group rocks in the hills east of upper Crooked Creek were recognized by USGS geologists in 1915 as the probable source of the placer gold.

In the 1970s Calista Corporation, an Alaska Native Corporation, as part of its land grant under ANSCA selected the land east of Crooked Creek, based on its mineral potential. In 1986 modern hardrock exploration of the Donlin area began with WestGold's efforts, which were abandoned after two years, due not to the lack of gold, but to the refractory (technically difficult to extract from the rock) nature of the gold. PlacerDome signed a lease with Calista and began exploration at Donlin in 1995. That effort continues today, having evolved to a 50:50 partnership between Barrick Gold

, in cooperation with Calista, the landowner. Over 150 million dollars have been expended on exploration, engineering, and environmental studies.

If eventually exploited, the mine will be an open pit several miles wide. Latest estimates (April 2009) report that Donlin contains 29.3 million ounces of proven and probable gold reserves (calculated at a gold price of $750) and an additional 10 million ounces of gold resource. The gold occurs within the crystal lattice of arsenopyrite associated with other metal sulfides in veins, veinlets, and disseminations mainly in the felsic dikes, but also in less common altered mafic dikes and in the sediments.

Iditarod District

The Iditarod district lies between the lower Yukon and Kuskokwim Rivers: the Aniak district abuts it to the south. A gold rush followed the discovery of gold on Otter Creek in 1909. Over 1.5 million ounces of placer gold and a few thousand ounces of lode gold have been recovered from the Iditarod area, making it one of the more important gold-mining districts in Alaska.

Tolstoi District

The drainage basin of Tolstoi Creek, a north-flowing tributary of the Dishna, roughly defines the district. The district lies between the Iditarod and Innoko districts. Placer gold and platinum were discovered by drifting in frozen gravels 35 feet deep on Boob Creek in the winter of 1915-1916. A gold rush occurred in the district the following winter. Historic production of 11,000 ounces of gold, as well as some byproduct platinum, is recorded for the district.

Innoko District

The Aniak district lies to the south, the Tolstoi district to the west. Almost 3/4 million ounces of placer gold has been won from Innoko River and its tribuaries in the district. Lode gold production of 150 ounces is also recorded. Cripple, Colorado, Yankee, Ganes, Ophir, and Little Creeks had prominent placer mines: a third of the districts production came from Ganes Creek. Gold-bearing porphyritic intrusive rocks adjacent to the Ganes Creek and Colorado Creek placers are similar in composition and age to the dike swarms at 29-million ounce Donlin Creek.
Ganes Creek

The property is located approximately 40 km west of McGrath, and 440 km northwest of Anchorage. Ganes is famous for producing spectacular gold nuggets including the 5th (122 troy ounces) and 13th-largest (62.5 troy ounce) in Alaska. The presence of cobble-size quartz with sulfide boxwork and coarse gold suggest that the placer gold is primary, originating from bedrock sources. Historic production figures from Ganes Creek are in excess of 250,000 oz. gold; an additional estimated resource of 736,000 oz. of placer gold exists on patented claims.

Ore consists of shoots of massive sulfides and native gold found with skarns along the contact of sedimentary rocks and the Mystery Creek quartz monzonite stock.The mine was reopened for exploration, permitted, and developed by Nevada Goldfields, Inc. in 1995 and operated until 1999. In 2005 resource and exploration development resumed. Gold production occurred in 2006 and 2007, production is currently suspended. Production has totaled 187,000 ounces of gold, 2,190,000 pounds of copper, and at least 11,000 ounces of silver. Two small ore bodies have proven and probable reserves of approximately 126,400 tonnes, containing 133,730 ounces of gold. An additional 116,000 tonnes of existing mill tailings are reported to contain 30,200 ounces of gold.

 in the spring of 1899. Construction of a new hardrock gold mine at Rock Creek was completed, and start-up procedures initiated in late 2008. Efforts at the new mine are suspended due to mill design inadequacies and difficulties meeting regulatory requirements. NovaGold's Rock Creek project includes the Rock Creek mine and mill complex seven miles (11 km) north of Nome, and eventual additional millfeed from the historic underground Big Hurrah mine site 42 miles (67.6 km) east. Over 3.6 million ounces of gold have been recovered from the Nome district, almost all of it from placer deposits.

 and mining using gold pans, sluiceboxes, rockers, suction dredges, and metal detectors, is enjoying a resurgence in Alaska.
There are many commercial ventures that charge fees to recreational miners located on historically-rich placer ground, some are road-accessible, many are in remote fly-in locations, most offer lodging and a complete suite of services.

Much of the State and Federal-owned land in Alaska is open to recreational mining but there are regulations governing how such mining can be done.

It is illegal to mine on public land that is closed to such activities; or to mine without permission on either public land that is already staked or leased, or privately-owned land.
