[1] Gold occurs and has been mined throughout Alaska, except in the vast swamps of the Yukon Flats, and along the North Slope between the Brooks Range and the Beaufort Sea.

Areas near Fairbanks and Juneau, and Nome have produced most of Alaska's historical output and provide all current gold production as of 2021[update].

The Funter Bay underground lode mine produced about 500 thousand tonnes of copper-nickel-cobalt ore, without gold, from a Mesozoic gabbro-norite pipe.

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.

Pleistocene ice sheets from the Brooks Range and cirque glaciers in the Ray Mountains covered much of the higher elevations.

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.

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.

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.

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).

Placer mines in the Zane Hills on Bear Creek, a tributary of the Hogatza River, are the biggest source of gold from the district.

[30] The mine is located in the remote Kaiyuh Mountains of west-central Alaska about 40 miles (64 km) south of the Yukon River village of Galena.

The Illinois Creek lode gold-silver mine exploited a shear-hosted gold deposit which was partly expressed as color anomalies visible from aircraft.

Uplands with thousands of feet of generally mild relief are underlain by a complex metamorphic terrane intruded by a broad range of igneous rocks.

By 1939, large, deeply buried (80 to 110 feet), thawed, bench placer deposits on the northwest limit of Livengood Creek valley were defined.

Placer mining began near Fairbanks in July 1902, after Felix Pedro (real name Felice Pedroni), an Italian immigrant and Tom Gilmore discovered gold in the hills north of the Tanana and Chena Rivers in 1901.

A private 49-mile (79 km) gravel access road and power line connects the mine to the Richardson Highway near Delta Junction.

The mining boom ushered in a wave of settlement that forever changed the place, not only for its new residents but for the Athabascan Indians who occupied this region long before them.

[42] Reports of starvation and lawlessness among the miners resulted in the Army sending troops to the Eagle area to provide law enforcement in 1899.

[47][48][49][50] The KGB includes all or parts of the historic Aniak/Tuluksak, Anvik, Bethel, Goodnews Bay, Iditarod-Flat, Innoko, Marshall, McGrath, Ruby, and Tolstoi mining districts, as well as newly realized gold-rich areas.

[47] The Marshall and Anvik districts produced about 124,000 troy ounces of gold (8,500 lb; 3,900 kg) and minor amounts of platinum, mainly from Wilson Creek.

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.

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.

Extensive geochemical and geophysical surveys during the past several years have identified areas with as much as 0.1 ounce per ton platinum in the soils, but no reserve has been demonstrated.

Surveyors belonging to the 1865 Count Bendeleben expedition exploring a route across Siberia, the Bering Sea, and Alaska for a communications cable reported gold in the Fish River area of the Seward Peninsula.

[57] Placer gold deposits on Anvil Creek and on the Snake River, a few miles from the future site of Nome, were discovered in 1898 by Jafet Lindeberg, Erik Lindblom and John Brynteson, the "Three Lucky Swedes".

The mine began producing gold in September 2008, but permanently ceased in November 2008 due to difficulties with the ore crushing and grinding circuit.

The district (including Candle) produced about 600,000 ounces of gold with minor amounts of chromium, copper, lead, platinum, bismuth, tungsten, mercury, molybdenum, silver, and rare-earth elements.

Valdez Creek, a tributary of the Susitna River, is located in central Alaska northeast of milepost 81 on the Denali Highway.

Cambior's Valdez Creek Mine recovered over 75,000 ounces of gold annually, making it the largest placer operation in North America in 1992.

[70] The Hatcher Pass Public Use Area is located approximately fifteen miles north of Palmer on the Little Susitna River.
