In a statement, Zimplats said ground conditions had been deteriorating along a fault line that was detected in 2011.
Bimha Mine, located more than 200km southeast of Harare, is the biggest of four Zimplats platinum mines in Zimbabwe.
“"As a result, production from the Bimha Mine has been down-scaled by 50 percent equating to 45,000 ounces of platinum in matte production," Zimplats said.
It was not immediately clear what action the company had taken to counter the deterioration in ground conditions that culminated in the collapse.
Zimbabwe has the world’s largest known platinum resources after South Africa.
Zimplats is part of the South Africa-based Implats, which recently came out of a 19-week industrial job action that resulted in the loss of 2,800 ounces of platinum.Post published in: News
