The world's largest platinum producer also announced that it had acquired Glencore 39 percent stake in Mototolo, a mechanised platinum mine on the eastern limb of South Africa's platinum belt.

"The acquisition of Glencore’s stake in the Mototolo JV increases Amplats' interest in a mechanised, low-cost, high quality resource," Chief Executive Chris Griffith said in a statement.

The company, a unit of Anglo American, reported headline earnings per share of 1,282 cents, in line with its guidance.

It declared an interim dividend of 374 cents per share. In February, the company announced its first dividend in seven years.
