Dioro gold output suspended on Mount Marion pit wall failure

摘要

AUSTRALIA-based Dioro Exploration NL has warned that a wall failure at the Mount Marion open-pit gold mine in Kalgoorlie where the company is extracting the remnant crown pillar has temporarily prevented access to about 13,000oz of gold. In excess of 125,000 bank cubic metres (bcm) of soft overburden material slipped from the upper portions of the pit wall, the company said. Dioro, which is processing gold contained in blasted broken ore stocks at an average grade of 4.5g/t Au at the bottom of the Mount Marion pit, said it anticipated that the remediation of the slip and making the pit walls safe for re-entry would delay gold production at the pit by two months. "Initial analysis indicates that none of the ore reserves temporarily affected by this event have been sterilised/'the company said.
