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.

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.

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.

California

- The most famous gold region of California is the Mother Lode Country located in the north-central part of the state and includes an area that spans approximately a hundred and fifty miles from north to south along the western slopes of the Sierra Nevada Mountains.
