Gold can be broken in both underground mines and outbreaks, or be a by-product of extraction of other metals, but since today we have the highest gold price for a long time, the pure gold mining makes sense for its name. Traditional gold laundering, on the other hand, is rarely commercially viable anymore than a tourist attraction.

Gold is rare, and it takes a lot of resources to extract small quantities. Therefore, it is possible to measure the value of a gold mine, not just how much gold is found in the soil, but also how much gold can be extracted per ton of pulp (as well as a number of other factors). But measured in total reserves the following gold mines are good at:

Withersrand Basin: Mine, South Africa

In Johannesburg, South Africa lies Withersrand Basin, which is the largest gold deposit throughout the ages. According to some estimates, almost half of all gold is ever recovered from here. In the 1970s, the mine represented a majority of the world's gold production - a production still underway in incredibly deep and extensive mining tunnels. It takes about two hours for miners to get back to the surface from the deepest shaft in Withers and Basin.

Grasberg: open outbreak, Indonesia

Grasberg is an outbreak at 4 500 meters high in Iran Jaya, Indonesia. The breakthrough is the world's largest gold mine and the third largest copper mine. It also produces a lot of silver. From the actual breakthrough, 225,000 tons of ore are broken daily refined into precious and industrial metals. In addition, Grasberg has underground operations. In total, 610 800 tonnes of copper, 174 458 971 grams of silver and 58 474 392 grams of gold were produced in 2006 (reported).

Murantau: Open outbreak, Uzbekistan

Murantau is run by State Navoi Mining in Uzbekistan and is located about 40 miles west of the capital Tashkent. The crash was discovered in 1955 by the then Soviet Union and still produces large amounts of gold. The exact amount produced in recent years is unknown, but the mine was formerly one-third of Soviet gold production. Today, Uzbekistan is collaborating with the US mining company Newmont Mining.

The Super Pit: Offense, Australia

The Super Pit is as the name suggests a super-sized hole in the ground - or the world's overtaking breakthrough - and is found in Kalgoorlie, Australia. The hole covers several square kilometres and is large enough to be visible from space. The history of the mine extends over 100 years in the past and has been operating both below and above ground. After the mine has been emptied around 2017 it will be filled with groundwater - a process that is estimated to take 50 years.

Yanacocha: Open outbreak, Peru

Another giant breakage is Yanacocha, which is high in the Andes of northern Peru. To the surface, the area covers 251 square kilometres, but it does not consist of an individual "big hole" like the Super Pit. So far, it has gained gold worth seven billion dollars, making the gold mine one of the world's most profitable, and because of the high gold price per gram today it's more profitable than ever.

American Newmont Mining operates the mine together with Peruanska Buenaventura, but there has been a lot of trouble about who will gain gold in Yanacocha. The state French mining company BRGM also had a part in the mine but was challenged by Newmont and Buenaventura in a sphere of espionage and intrigue. The area is also plagued by environmental problems due to the mine.
