Anglo Platinum said it had received an additional $1bn capital injection this month to help it cope with ongoing weakness in the platinum market, but, as it revealed first half earnings, signalled it would not need to increase its debt for at least the next 12 months.

The company, which is 80 per cent owned by London-based mining group Anglo American, has struggled to lower its costs after the platinum price collapsed from record heights of $2,230 an ounce last year.
