Harmony Gold is considering going further underground at the world's deepest mine.
The company is one of the few remaining SA gold producers squeezing profits from aging assets.
Harmony is backed by billionaire Patrice Motsepe's African Rainbow Minerals.
Harmony Gold Mining is considering going further underground at the world’s deepest mine as South African producers find it harder to dig for dwindling ore reserves.
The nation’s top producer is studying mining beyond the current depth of about 4 kilometers at Mponeng to potentially extend the mine’s life by 20 to 30 years, Chief Executive Officer Peter Steenkamp said. Ore reserves below that level are “massive” and Harmony is exploring ways and the investment needed to tap them, he said.
