Global giant, Anglo American has pointed out that several unprotected strikes have affected production at the Anglo American Platinum (Amplats) and Kumba Iron Ore during the third quarter of the financial year.

Amplats said that unprotected strikes affected production during October and November at several facilities including Rustenburg mines, Union and Amandelbult mining operations. Amplats, in which Anglo American has a stake of 80 per cent, was able to offset the fall in production by selling pipeline stocks.

The company said that its refined platinum production during the quarter from October to December, 2012 fell 34 per cent quarter on quarter to 416,000oz. The total equivalent refined platinum production was down 8 per cent during the whole year to 2.219-million ounces.

"Production and costs for 2012 were impacted by the illegal industrial action and the subsequent ramp-up, with 273,000oz of equivalent refined platinum production lost during the fourth quarter of 2012," Amplats said.

Leaders of the African National Congress have demanded that the rights over non-operational assets should be seized and auctioned in order to save jobs. Mineral Resources Minister Susan Shabangu has assured that the department would review Amplats's and Anglo's mining rights compliance.
