Sibanye Gold aims to show its faith in platinum with further acquisitions while looking to benefit from a broader commodities revival by strengthening its portfolio of gold, base metals and coal assets. The South African company bought Anglo American Platinum’s (Amplats) Rustenburg mines in September for R4.5-billion ($287-million) and forked out $294-million for Aquarius Platinum a month later, expanding in a sector damaged in 2014 by a record five-month stoppage that dented Amplats’ profits.
