Based on production data made available in 2010, let’s take a look at 10 largest gold mines found in the world.

There are some variety in opinion when it comes to which gold mine deserves the ranking of Number 1. Some opinions believe that by production, the largest gold mine in the world is the Muruntau gold mine found in Uzbekistan. However, others believe that position should be given to the Gasberg gold mine found in Indonesia. At the end of the day though, most of the opinions weight towards claiming Grasberg as the largest mine found in the world.

Another problem that is causing a difference in opinion is on how much these mines below are actually producing. It is often difficult to gain figures on yearly productions, on top of the production data not being standardized as well as the data not being calculated based on the same calendar.

Besides reports that come from the mining companies themselves, the most valuable sources come from the Raw Materials Group in Sweden, the Intierra Resource Intelligence in Australia, and the Metals Economics Group in Nova Scotia.
