Gold Distribution in the USA. The distribution of gold in the US is uneven. Most gold deposits are in Alaska, California, Nevada, Colorado, and Arizona. Most of the main gold-producing districts are in the mountainous areas of the United States, where folding, faulting, and igneous intrusions have deformed the rocks.
May 27, 2019 · Gold rushes occurred in the mid- to late-19th century, primarily along North America’s West Coast from California to Alaska. In Canada, key events included the Fraser River, Cariboo and Klondike gold rushes, as well as the Fraser Canyon War and the founding of British Columbia as a colony in 1858. The worldwide production of gold tripled ...

There are various ways to separate and recover gold, depending upon the nature of the ore. When gold occurs in a relatively coarse, free state, it can be recovered by mechanical means such as gravity traps and shaking tables, where the gold separates out because of its high specific gravity. Cyanidation is a chemical process used to recover gold th...
Gold is found across the Canadian Shield, in British Columbia and Nunavut, and on the island of Newfoundland. It was first discovered in Canada in 1823 along the shores of the Rivière Chaudière in the Eastern Townships of Québec. In 1858, following the famous rushes in California and Australia, gold was discovered in the sands of the Fraser River i...
The first to prospect and mine in North America were Aboriginal peoples who used minerals, including gold, copper, silver and cobalt, for tools, weapons, art and other objects. They discovered gold throughout the Pacific northwest and their attempts to defend their claims led to the Fraser Canyon War of 1858 and the formation of Indian reserves in ...
Canada's mining industry is expending tremendous effort to overcome a long history of environmental damage. One example of mining's environmental impact is gold mining's release of thousands of tonnes of toxic mercury and cyanide into the environment. In 2004, the Mining Association of Canada (MAC) began promoting a program called "Towards Sustaina...
- In the rocky sediment of Nevada’s deserts. Nevada currently produces almost 75 percent of the annual U.S. gold yield. While this is primarily through professional mining, the state still allows people to recreationally pan—or more frequently, metal detect—for pieces of gold on publicly owned land.
- Along the American River in California. Gold panning along the 119-mile American River east of Sacramento is nothing new—it’s where the California Gold Rush started.
- Throughout the Alaskan Yukon River. Alaska has been a draw for prospectors since 1896, when gold was discovered in the Canadian Yukon, beginning the Klondike Gold Rush.
- In former Colorado mining hot spots. The Cache Creek mine in Twin Lakes, Colorado, was a successful operation for over 50 years. When it closed in 1911 as a result of an environmental lawsuit, the area’s gold was far from depleted.
The U.S. Geological Survey (USGS) Mineral Resources Data System catalogs information about mineral resources around the United States and the world. Using the map tool, users can zoom in to obtain reports and data on past and present mines, mine prospects, and processing plants. All of the data can be downloaded for further use and analysis. The image above comes from the overview map focusing ...
North Carolina was the site of the first gold rush in the United States, following the discovery of a 17-pound (7.7 kg) gold nugget by 12-year-old Conrad Reed in a creek at his father's farm in 1799. The Reed Gold Mine , southwest of Georgeville in Cabarrus County, North Carolina produced about 50,000 troy ounces (1,600 kg) of gold from lode and placer deposits.
