The Ruby-Poorman District lies south of the Yukon River. The district produced nearly a half million ounces of gold, all from placer mines. The largest gold nugget ever found in Alaska (294.1 troy oz) was recovered from Swift Creek in 1998. [33] The placers are mostly deeply buried, and most were originally worked with shafts and drifts.
The Independence Mines, now Independence Mine State Historic Park, is the site of a former gold mining operation in the Talkeetna Mountains, across Hatcher Pass from Palmer, Alaska. The area's mining history dates to at least 1897, when active claims were reported in the vicinity of Fishook Creek.
Gold mining is one of the most common uses for the staking of mining claims. In Alaska, state mining claims may be up to 160 acres (0.65 km 2), and there is no distinction between lode or placer claims. The boundaries of the claim must follow the 4 cardinal directions, with an exception being adjustments for existing valid claims.
This list of gold mines in the United States is subsidiary to the list of mines article and lists working, defunct and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marble and other quarries may be included in this list.
Gold-quartz-sulfide hydrothermal vein at the old Grant Mine, Fairbanks Mining District. The Fairbanks mining district is a gold-mining area in the U.S. state of Alaska. 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.
The 1910 explosion was the worst disaster in Alaska mining history. [7] The mine was still yielding gold in 1917 when the Treadwell, 700-Foot and Mexican mines (excavated to a depth of more than 500 feet (150 m) below sea level under Gastineau Channel) suddenly began leaking and were evacuated. Hours later the mines collapsed.
The Nome mining district, also known as the Cape Nome mining district, is a gold mining district in the U.S. state of Alaska.It was discovered in 1898 when Erik Lindblom, Jafet Lindeberg and John Brynteson, the "Three Lucky Swedes", found placer gold deposits on Anvil Creek and on the Snake River few miles from the future site of Nome.
The Ruby–Poorman mining district in the U.S. state of Alaska 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 along the Yukon River. [1] The placers are mostly deeply buried, and most were originally worked with shafts and drifts.
