South African mining stocks including Lonmin and Sibanye Gold rallied after precious-metal prices climbed as investors scaled back bets on a US interest-rate increase in September. Lonmin, the third-largest platinum producer, gained as much as 24%, the most since November 2008. Aquarius Platinum rose as much as 14%, the most since September 2012, while Sibanye Gold jumped as much as 13%, the most on record, to the highest since August 3. The ten top-performing stocks on the Johannesburg Stock Exchange were resource-related. Gold and platinum advanced to one-month highs after Fed officials signaled concern over low inflation and said they want to see the labor market improve further, according to minutes released Wednesday of central bank's July meeting. The rand's slump to a 13-year low on Thursday is also boosting miners, who sell their exports for dollars while paying costs in the local currency.
