The Boddington gold and copper deposit, located 75 miles southeast of Perth, Australia, is the country’s largest gold mine. The first gold was poured in 2009, and in 2011 Newmont produced its first one million ounces from the site. The mining company has identified gold reserves of 19.5 million ounces at Boddington and plans to spend half a billion dollars to expand production.
Gold was first discovered on Papua New Guinea’s Aniolam Island in 1982, and in 1997, the first gold was poured at the Lihir project, then managed by Rio Tinto. Australia-based Newcrest acquired the gold deposit in 2010 and has since struggled to keep operation costs under control. The company recently announced that expansion will cost a lot less expensive than initially thought, owing to new processing equipment that can more easily handle sulfur.
Wholly owned by Canadian miner Goldcorp, the Peñasquinto mine is located in the State of Zacatecas. It’s the largest open pit mine in Mexico and the fifth largest silver mine in the world. Besides gold and silver, the project, in operation since March 2010, also yields zinc and lead. In 2007, Silver Wheaton entered into an agreement with Goldcorp to buy 25 percent of all silver output for the life of the mine.
Whether we’re talking about glittering Las Vegas casinos or mining, gold and Nevada are nearly synonymous. The state accounts for 75 percent 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. Much of this comes out of the state’s Carlin Trend, the most abundant goldfield in the Western Hemisphere. Along the trend is Newmont’s historic Carlin project, which consists of three open pits and four underground mines. In May 2015, the company celebrated 50 successful years of gold production at the site, which was the first in North America to generate more than one million ounces in a single year.
At more than 15,000 feet above sea level in Northern Peru, the Yanacocha project sits atop the Andean continental divide. It’s the largest gold mine in Latin America, covering some 535 square miles. Consisting of five open pit mines, it’s been producing gold since August 1993. Ownership of the mine is split among Newmont; Minas Buenaventura, a Peruvian company; and the International Finance Corporation, controlled by the World Bank.

Barrick employs 4,000 people in Nevada, or about a third of the state’s entire mining industry labor force. Many of these people work at the company’s Cortez operation, located in central Nevada. 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.
