Gold have been mining in the United States since 1799, when it was discovered in North Carolina. California, Nevada and Alaska are famous for their gold discoveries, but many people don't realize that gold can be found in almost all 50 states.

Nevada
is the Number 1 gold producing state and at the same time the most mineral rich state in the U.S. The state accounts for 75% of total U.S. output, and it’s even estimated to be responsible for producing 3 percent of all gold ever mined in human history.Largest gold mines:

The Cortez gold mine
located 100km south-west of Elko (Lander County, Nevada) is currently the 9th largest gold mine in the world. The mine contains a gold reserve of nearly 15Moz (425 tonnes) including 2Moz of proven and 13Moz of probable gold reserves. Gold production from Cortez started in 1969. The mine employs both open-pit and underground mining methods. Cortez gold mine is owned and operated by Barrick Gold. As one of Barrick’s most promising ore bodies, the site is scheduled to receive $153 million from the company through 2020. This will help expand its underground mining capacity, allowing it to produce an additional 300,000 ounces per year.–
Carlin Trend gold mine
(operated by Newmont) in Nevada is the 8th largest in terms of contained gold reserve. The mine consists of a belt of sedimentary rock-hosted gold deposits that are about 5 miles wide and 40 miles long. Newmont started open-pit mining at Carlin in 1965. Underground mining was started in 1994. The operation includes open pit mines (Carlin main pit, Genesis, Post, Gold Quarry, Beast, Bootstrap, Sold and Lantern) and four underground mines - Carlin East, Chukar, Deep Post and Leeville. The mine’s total proven and probable reserves amount nearly 15 Moz (425 tonnes) of gold.–
Goldstrike mine
- The mine is located in north-central Nevada and is operated by Barrick since 1987. As the largest gold mine in North America, Goldstrike employs about 1700 people. Over the last couple of decades, workers have developed a new way to process ore at the site, known as “total carbonaceous matter leach,” which will allow the company to repurpose lower-grade ores.Since the purchase of
Alaska
from Russia in 1867, gold mining has played a major role in Alaska's history.It is no secret that the state is one of the great destinations that gold miners seek out to search for gold, and for good reason. Tons of gold are digged in the state over the last century, and plenty of the mineral continues to be in the ground waiting to be found.
Largest gold mines:
–
Fort Knox Mine
is located 25 miles northeast of Fairbanks and is the largest gold producer in Alaska and produces 900 ounces of gold per day.–
Crow Creek Mine
, is one of Alaska's most renowned hydraulic gold mining operation. With estimated production rate of 700 ounces per day.–
The Pogo Mine
near Delta Junction produces 400,000 ounces of gold per year and is an underground mining operation.–
