The increase in production was supported by a surge in global commodity prices in the period and was underpinned by strong performance in gold output which surged 7.7percent in August compared to 5.8% recorded in July.
Diamond production inched up 27.7% in August compared to 16.6% in the previous month, while iron ore, which rebounded 9% compared to a decline of 5% in the previous month.
On a monthly basis, mining output went up 5.3%. John Ashbourne, an Africa economist at Capital Economics, says August mining production figures suggest that the sector remained strong in the middle of the third quarter.
“This marked the sector’s strongest growth since March. The gold, iron and diamond sectors made the largest contributions to growth.
"But output rose across almost the entire mining industry, with copper the only sub-sector in which output fell year-on-year,” Ashbourne says.
The mining production figures were the second set of positive data that took the markets by surprise, after manufacturing production data also exceeded expectations - indicating that the economy has been on a sound footing in the third quarter.
The rebound in the manufacturing sector was pretty broad-based, with seven of the 10 sub-sectors performing better in August than they did in July. At the seasonally adjusted, 3-month-on-3-month rate that aligns with official GDP figures, growth in the manufacturing sector picked up to a 22-month high of 1.3%.
