Jun 9, 2022Gold mining is a global business with operations on every continent, except Antarctica, and gold is extracted from mines of widely varying types and scale. At a country level, China was the largest producer in the world in 2021 and accounted for around 9 per cent of total global production. Our interactive gold mining map provides a breakdown of the top gold producing countries in the world, which demonstrates the geographical dispersion of gold mining operations and the gold supply.

On June 2, 1988, 33 nations agreed to a framework to regulate mining exploration and development in all Antarctica. A key to the convention's approval is that, like all the Antarctic treaties, it sidesteps the issue of whether the seven nations who assert sovereignty over different regions of Antarctica have a rig-htful claim.

The minerals found in Antarctica are silver, copper, molybdenum, lead, zinc, gold, chromium, manganese, titanium, cobalt, iron, nickel and uranium. The countries that are owners of the land in Antarctica are not allowed to mine the minerals as they have signed a treaty saying they are not allowed to. This means no one owns the minerals but they do take care of the land that covers the minerals and metals.
