PERTH (miningweekly.com) – Junior Kingsrose Mining has resumed mining operations at its Way Linggo openpit mine, in Indonesia, following a wall failure late last month.
The company at the end of June reported a fault had been identified in the north-east pit wall and was being closely monitored by the site geotechnical team and prior to its failure, material movement had been detected for some days.
The wall slippage occurred during normal working hours, however, the mining activities had already been stood down and personnel and equipment had been removed from the mapped potential sliding zone.
Kingsrose subsequently engaged a specialist external geotechnical consultant to assist with the assessment of the fall and the optimal remediation of the pit’s north-east wall, with the miner on Monday confirming that normal mining activities have resumed.
The wall failure is expected to result in the processing plant being stopped for four to five weeks, with operations set to resume at the end of the first week of August.
The wall failure has led to an estimated 4 000 oz of gold being removed from the mine plan after the pit redesign.
