Mineral resources

Mining in Antarctica would be very difficult, dangerous and expensive as the climate is so harsh, the ice is very thick and Antarctica is very remote from major centres of population.

Warm up

There are known reserves of oil and coal as well as mineral deposits in Antarctica, although detailed knowledge of these mineral deposits is sketchy. In the last 50 years of scientific research, no large deposits of mineralized rocks have been found.  Mining in Antarctica would be very difficult, dangerous and expensive as the climate is so harsh, the ice is very thick and Antarctica is very remote from major centres of population. This would make the transportation of minerals and equipment in and out of Antarctica hazardous. Drilling would also be difficult because of the vast quantities of moving ice and glaciers as well as the huge depth (5km at its thickest) that would be required to drill to reach the minerals making it too expensive to be economically viable.

Could all this change in the future? Could climate change make the Antarctic more accessible and drilling easier? Could vital supplies of oil in other areas run out, making Antarctic oil economically viable? Would the Antarctic Treaty Consultative Parties be under too much pressure to lift the ban on mining? The ban on mining, as found in Article 7 of the Protocol, can be subject to review in 2048 onwards.

What does the Antarctic Treaty say about mining?

There has never been any commercial mining in Antarctica thanks to the Antarctic Treaty which has completely banned mining under the Environmental Protocol. When the original treaty was signed in 1959, mining was not incorporated let alone formally discussed. The mining issue was first raised in 1970 by the UK and New Zealand who had been approached by mineral companies who were interested in exploration in the Southern Ocean.

Between 1982 and 1988 a set of tough environmental protection measures were set out under the Convention on the Regulation of Antarctic Mineral Resource Activities (CRAMRA). Under the convention, mining could take place if all parties agreed that there was no risk to the environment. The aim of the convention was to have a framework in place in the advance of any future mining. In 1989, France and Australia refused to sign the convention, saying that no mining should be allowed to take place in Antarctica – period. CRAMRA never entered into force but helped to provide the framework for the Environmental Protection Protocol. This entered into force in 1998.

Debate: Should the ban on mining be lifted?

Imagine it is 2047. There are calls to review the Antarctic Treaty ban on mining in Antarctica which is up for review next year.Oil reserves are almost completely depleted elsewhere and although the use of renewable resources such as solar and wind energy have increased substantially, the demand for the last remaining reserves is huge.

The price for a barrel of oil is now high which would make oil extraction in Antarctica and the Southern Ocean economically viable and profitable. In addition, climate change has led to the retreat and thinning of ice sheets, making drilling much easier and less dangerous. Arctic resources have been depleted a decade earlier. Other reserves of minerals are also almost exhausted such as iron ore and copper.

Mining companies are campaigning hard to have the ban lifted, while conservationists oppose the move. The Antarctic Treaty Consultative Parties have called an emergency meeting to discuss the future of the ban on mining in Antarctica.
