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.

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.
