Few new mines are being discovered to provide the newly wealthy in countries such as China with Western-style jewellery. Russia, Ukraine and China, among other countries, have been more active in surveying Antarctica in recent years.Īnd demand for diamonds is likely to outpace supply in coming years. Riley said there was a fine line between geological mapping and prospecting with an eye to mining. "We do not know what the Treaty parties' views will be on mining after 2041 or what technologies might exist that could make extraction of Antarctic minerals economically viable," said Kevin Hughes, of the Scientific Committee on Antarctic Research. And diamonds are already mined today in some of the world's colder reaches of northern Canada and Siberia. Gold (Other OTC: GDCWF - news), platinum, copper, iron and coal have also been found in Antarctica. "There is likely to be little opposition to an extension of this prohibition, despite the potential discovery of a new type of Antarctic 'ice'," Nature Communications said in a statement.īut another expert said the future was not so clear. Many expect the ban on mining to be extended in 2041. The Antarctic Treaty is binding only on its 50 signatories, but it has the backing of major powers, including the United States and China. "It's a big leap from here to mining," he told Reuters. Less than 10 percent of the deposits of similar kimberlite are economically viable, said Teal Riley of the British Antarctic Survey.

Others geologists doubted the find held much commercial value. "I don't think it's terribly practical that anyone could actually explore successfully and, personally, I hope that mining does not take place," Yaxley said. The 1991 environmental accord banned mining for at least 50 years. Antarctica is not only forbiddingly cold and remote but also protected by a treaty that preserves the continent for scientific research and wildlife, from penguins to seals. That does not mean Antarctica will soon see its own diamond rush. Kimberlite is a rare rock where diamonds are often found it is named after the South African town of Kimberley, the site of a late 19th-century diamond rush. Writing in the journal Nature Communications, an Australian-led team reported finding the kimberlite deposits around Mount Meredith, in the Prince Charles Mountains in East Antarctica. "It would be very surprising if there weren't diamonds in these kimberlites," Greg Yaxley of the Australian National University in Canberra, who led the research, said in a telephone interview. No diamonds were found, but researchers said they were confident the gems were there. OSLO, Dec 17 (Reuters) - A kind of rock that often contains diamonds has been found in Antarctica for the first time, hinting at mineral riches in the vast, icy continent - where mining is banned.
