Copper-based experiment leads academic to find new way to treat cancer

Suriname's only commercial gold mine, the Rosebel Gold Mine which is majority owned by Canada's Iamgold, has been shut down by a strike by 1,100 workers protesting new longer shift hours. Rosebel is located some 118 kilometers south of Paramaribo (pictured), the capital of the South American nation. The mine produced 395,000 ounces in 2010 at cash cost of $484 per ounce. While Rosebel is the country's only commercially operated mine, there are believed to be thousands of small scale miners operating in the tiny, impoverished country.

Base metals miner Metorex is expected to delist from the JSE in early December, following the completion of a takeover by Chinese group Jinchuan which made a R9.1bn ($7.3bn) offer for Metorex last month.

The iron ore division is expected to contribute nearly 80 per cent of the net profit, lifting its performance by more than 50 per cent a year ago to about $US6.2 billion.

Australia's Treasurer Wayne Swan may soon have another foreign investment headache on his hands, as a Chinese entrepreneur says he has Beijing's backing to step around Australian investment rules and become the world's fourth force in iron ore. Liu Han, chairman Hanlong Group said the company could achieve it within 10 years, giving China ''a say'' in iron-ore price negotiations and stem as much as $80 billion in national losses flowing to the big producers.

A strike in South Africa's gold mining sector ended on Tuesday after a 2-year wage deal was clinched, unions and the Chamber of Mines said. The strike at AngloGold Ashanti , Gold Fields and Harmony began last Thursday and halted output worth up to $25 million a day at bullion's current record prices. About 100,000 gold mine workers will to return to work, starting with the Tuesday night shift.

Businessweek quotes a confidential report prepared for South Africa's mining CEOs as saying South Africa’s ruling party is closer to some form of nationalization than at any other time since the end of apartheid. A government takeover of mines could choke investments in a country with metal and mineral reserves estimated at 2.5 trillion and lead to a collapse of the currency, the rand. Firebrand Julius Malema (pictured), the leader of the youth wing of the ruling African National Congress which often acts as kingmaker in the country’s politics, is spearheading the campaign to seize mines, farms and banks. Malema is never far from headlines in the country with racially charged comments but now an anti-corruption police unit is probing a trust fund owned by him allegedly being used to funnel payments in exchange for securing government tenders.

The Korea Herald reports a Korean consortium forged an agreement with Bolivia’s state-run miner Comibol over the weekend to manufacture lithium-ion battery parts, boosting Korea’s bid to tap the largest lithium deposits in the world. A research project involving extracting lithium will begin next month at Bolivia’s Salar de Uyuni – an 11,000 square kilometers salt flat (pictured) – with plans for constructing lithium-carbonate processing facilities. The soft, silver-white metal is widely used in rechargeable batteries for mobile phones, laptops and electric cars and the price has been steadily increasing prompting talk of a Opec-style cartel to control production and prices among South American nations that together control 85% of the world's resources.
